Caucasiana 2: 9-13 The invasion of alien plants into the territory of Georgia started in ancient times and continues today. Sicyos angulatus L., a species of North American origin, is an example of such an invasion. The first established populations of S. angulatus occurrence in Georgia were observed in 2012. Since then, new localities have been recorded, both in agricultural and disturbed natural communities. The species, which has easily adapted to local soil and climatic conditions, is expanding every year and is already widely spread in west Georgia. The plant is characterized by fast and intense growth and a climbing habit using other plants as a support. In this contribution, the peculiarities of its distribution in Georgia and the morphological features and life-history characteristics of Georgian populations are provided. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e96039 https://doi.org/10.3897/caucasiana.2.e96039 https://caucasiana.pensoft.net/article/96039/ https://caucasiana.pensoft.net/article/96039/download/pdf/ en

Parasite ecology of Carassius gibelio (Bloch, 1782) in Jandari Lake (Georgia) Murvanidze,Lali Nikolaishvili,Ketevan Lomidze,Tsitsino Japoshvili,Bella Arabuli,Lela Asatiani,Ketevan Protozoa Monogenea Nematoda Trematoda Copepoda eutrophic lake fish Caucasus Caucasiana 2: 15-23 The aim of the investigation was to study the current structure of the parasitic fauna of the gibel carp (Carassius gibelio) population in the Georgian part of Jandari Lake. In total, 423 young gibel carp collected during 2014-2018 years from Jandari Lake have been subject to parasitological examination. The 20.3% (n=86) of examined fish were invaded by 11 species of parasites belonging to 5 taxonomic groups. The dominant taxonomic groups were discovered to be Protozoa and Monogenea. The eight species were registered for the first time in the gibel carp of freshwater reservoirs in Georgia. In general, young fish were more invaded by the monoxenic species of the direct life cycle. None of the revealed parasites were specific to gibel carp. The parasitic fauna of Jandari Lake is relatively poor, though it is comparatively rich and diverse in spring. Trichodina sp. from Protozoa, Ancyrocephalus sp., Dactylogyrus vastator, Gyrodactylus elegans from Monogenea, and Contracaecum sp. from Nematoda were revealed as the species most sensitive to annual changes. The main factor determining the parasite fauna of gibel carp in Lake Jandari is anthropogenic eutrophication, which changes the qualitative and quantitative composition of zooplankton, the main food source of juvenile fish and intermediate hosts of helminths. The difference in invasion indices between female and male gibel carp was insignificant. The synergetic relationship between some parasitic protozoans and monogeneans was marked. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e95777 https://doi.org/10.3897/caucasiana.2.e95777 https://caucasiana.pensoft.net/article/95777/ https://caucasiana.pensoft.net/article/95777/download/pdf/ en

Georgia is situated in the middle of this area, between the ranges of the Greater and Lesser Caucasus, a position providing exceptionally balanced environmental conditions for its flora and fauna. Animal groups of low mobility, such as land snails, are important indicators of the past and present geographic and climatic events shaping these unique ecosystems. We give an overview of the land snail family Clausiliidae in Georgia that includes 30 species, among which eight are endemic to this country. Their distribution areas are reassessed in the light of novel georeferenced occurrence data resulting from recent field work. Aspects of the origin, diversity, habitat requirements and conservation status of the Georgian Clausiliidae fauna are discussed. Additionally, Mucronaria (Mucronaria) kartvelica sp. n. is described from the Racha-Lechkhumi and Kvemo Svaneti Region. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e101013 https://doi.org/10.3897/caucasiana.2.e101013 https://caucasiana.pensoft.net/article/101013/ https://caucasiana.pensoft.net/article/101013/download/pdf/ en

Due to the taxonomic uncertainty, the recorded specimens were considered potentially new taxa. Since then, no other record of Ametropus has been documented from the whole South Caucasus and its nearby regions further south. In the present contribution, we provide a new record of Ametropus from the Alazani River (Kura River Basin, Georgia). Morphological and DNA barcoding of the COI gene fragment showed that the species belongs to the widespread Holarctic species A. fragilis. Morpho-anatomical characteristics also confirmed the high degree of similarity between the newly recorded specimens and those once recorded 80 years ago. In addition, the COI barcode showed a strikingly closer relationship between Caucasian A. fragilis and North American A. neavei (3.54% divergence) compared to Caucasian and European A. fragilis populations (4.3% divergence). The observed pattern clearly indicates the need for further and more thorough revision of the Ametropus species complex in the Holarctic region. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e102622 https://doi.org/10.3897/caucasiana.2.e102622 https://caucasiana.pensoft.net/article/102622/ https://caucasiana.pensoft.net/article/102622/download/pdf/ en

Ground beetles (Coleoptera, Carabidae) from a winter excursion to Georgia, Southern Caucasus ecoregion Trautner,Jürgen Fritze,Michael-Andreas Schröter,Asmus Chaladze,Giorgi Faunistics biodiversity inventory new records survey methods Caucasiana 2: 113-125 Abstract In winter 2019, an excursion to the central and eastern parts of Georgia was conducted, focusing on arboreal species and other carabids overwintering under bark or at the base of trunks. Other habitat structures were also investigated. The work was done as part of ongoing studies in preparation of a new checklist of Georgian Ground Beetles and to contribute to the faunistic as well as ecological knowledge base for the main natural areas of this country. Forty-three taxa were recorded. The arboreal species Dromius agilis (Fabricius, 1787), the plant-dwelling species Demetrias imperialis (Germar, 1823), and Paradromius suturalis (Motschulsky, 1844), and another six species (Microlestes corticalis (Dufour, 1820), M. fissuralis (Reitter, 1901), M. fulvibasis (Reitter, 1901), M. luctuosus Holdhaus in Apfelbeck, 1904, Pterostichus leonisi Apfelbeck, 1904, and P. strenuus (Panzer, 1796)) are new for Georgia. In some sites, the number of recorded specimens under bark, in litter, or in the upper soil was very low, probably due to specific climatic conditions (e.g., very low humidity). It is supposed that in these areas, most of the individuals reside deeper in the soil during periods of low activity or hibernation. The number of Dromius individuals overwintering under bark near the stem base increased with altitude. The relevance of special survey methods in the winter for ground beetles is emphasized. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e102280 https://doi.org/10.3897/caucasiana.2.e102280 https://caucasiana.pensoft.net/article/102280/ https://caucasiana.pensoft.net/article/102280/download/pdf/ en

Here, we record the greater horseshoe bat (Rhinolophus ferrumequinum) and the lesser mouse-eared bat (Myotis blythii) as hosts of C. lectularius from two Georgian and one Armenian sites. A summary of all known published records of bat-associated populations of C. lectularius shows they are both scattered and restricted to the Palearctic only. Observations of C. lectularius from bat colonies in Georgia and Armenia were made in old buildings or ruins, like churches or monasteries, but not in caves, despite a specific search. This supports previous studies suggesting that 1) bat-associations of common bed bugs are very rare outside Central Europe and 2) almost never occur in caves. We discuss climatic conditions and host preferences as possible factors for these findings and the implications for the origin of the human bed bug interaction. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e104244 https://doi.org/10.3897/caucasiana.2.e104244 https://caucasiana.pensoft.net/article/104244/ https://caucasiana.pensoft.net/article/104244/download/pdf/ en

Species elevational richness gradient and species-area relationship in mountain vegetation of Javakheti highland (Georgia) Mumladze,Levan Shetekauri,Shamil Barnaveli,Nana Chelidze,Davit Asanidze,Zezva Caucasus species diversity distribution plants species-area relationship Caucasiana 2: 127-135 Elevational gradients in species richness and species-area relationships are among the most interesting patterns in ecology and biogeography. Both patterns can be characteristic of the same system; however, current knowledge of how these patterns co-exist and how we can disentangle their contributions to biodiversity structure is insufficient. In this article, we tested the effect of elevation and area on the formation of plant species diversity patterns in the forest-free Javakheti Highlands (Georgia). Samples (170 plots) were collected within elevations of 1400-3100 m, and the diversity distribution was examined in relation to altitude, available band area, and sampling. In total, 564 species from 67 families were recorded. Plant species richness was highest at mid-elevations (1900–2200 m), irrespective of area and sampling effort. This was in line with other studies from the Caucasus indicating the generality of plant elevational diversity patterns in the region. Area was not an important predictor of species richness; however, this may be considered a result of insufficient sampling. Our study shows that more research is needed to understand the effect of area on patterns of elevational biodiversity distribution. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e103599 https://doi.org/10.3897/caucasiana.2.e103599 https://caucasiana.pensoft.net/article/103599/ https://caucasiana.pensoft.net/article/103599/download/pdf/ en

Comparison of tree species diversity, deadwood volume and regeneration of managed and old-growth Oriental beech (Fagus orientalis L.) forests in Eastern Georgia Droessler,Lars Wolff,Tobias Caucasus coarse woody debris forest characteristics forest management old-growth forest regeneration density Caucasiana 2: 171-176 Abstract Main stand characteristics and tree species composition were studied in managed and old-growth Oriental beech (Fagus orientalis L.) forests in eastern Georgia (Caucasus). Oriental beech dominates both the regeneration layer and the upper story in old-growth forest. In managed forests, Caucasian hornbeam (Carpinus orientalis) and Oriental beech co-dominate the tree layer as well as the regeneration layer. Tree species diversity and deadwood proportion are higher in managed forests than in old-growth forests. However, the absolute deadwood proportion is similar in both studied forest types. Hence, deadwood proportion is not a suitable indicator to assess the naturalness or management intensity of forests in the study area. The observed proportions of Caucasian hornbeam in managed forests raise concerns about the sustainable use of beechwood in the long term. Harvesting hornbeam and smaller removals of beech are recommended to maintain the uneven-aged forest ecosystem, with Oriental beech as the dominant tree species. The established long-term study plots are important to observe and improve future stand development and forest management. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e106898 https://doi.org/10.3897/caucasiana.2.e106898 https://caucasiana.pensoft.net/article/106898/ https://caucasiana.pensoft.net/article/106898/download/pdf/ en

Checklist of Georgian centipedes (Myriapoda: Chilopoda) Kiria,Eleonora Barjadze,Shalva Tuf,Ivan H. South Caucasus endemic species species inventory review Caucasiana 2: 177-188 Abstract The Caucasus ecoregion is distinguished by its biodiversity. The flora and fauna of the ecoregion became the study area of many zoologists and botanists. Georgia, as a part of it, is important for its valuable and impressive diversity. However, despite many years of scientific research, certain groups, among them centipedes, are not so well studied. This is the first comprehensive summary of current knowledge about centipedes distributed in the territory of Georgia, based on literature data. It provides information about 59 taxa (57 species and two subspecies) known from Georgia, belonging to 16 genera in seven families from four orders. Nineteen species are endemic to the Caucasus, eight of which are Georgian endemics. Among them, two species: Cryptops datviensis Tuf, Barjadze, and Maghradze, 2022, and Harpolithobius birsteini Zalesskaja, 1972, are troglobiotic. Another four species (Lithobius caucasicus Sseliwanoff, 1881; Lamyctes coeculus (Brölemann, 1889); Lithobius semperi (Haase, 1887); and Scolopocryptops nigridus McNeill, 1887) are considered doubtful records. An overview of local and global distribution for each taxon is included. Lithobius fasciatus Muralevitch, 1929, syn. nov. is formally synonymized with Lithobius striatus Muralevitch, 1926. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Checklist text/html info:doi:10.3897/caucasiana.2.e108535 https://doi.org/10.3897/caucasiana.2.e108535 https://caucasiana.pensoft.net/article/108535/ https://caucasiana.pensoft.net/article/108535/download/pdf/ en

Soil mite (Acari: Oribatida) communities in the limestone quarry of Saskhori (Gerogia) Arabuli,Tea Gogshelidze,Mariam Caucasus Kartly Region Liacaridae Liacarus oribatelloides Caucasiana 2: 189-197 Abstract The present publication provides a review of the soil mite (Acari; Oribatida) community’s structure and the connection between changes in environmental factors and oribatid mite diversity in the limestone quarry of Saskhori and its adjacent areas. Overall, 52 species were recorded during the study. The most abundant oribatid mite species were Steganacarus carinatus, Aleurodamaeus setosus, Xenillus tegeocranus, Ceratoppia bipilis, Oribatula tibialis, and Punctoribates punctum. Interestingly, 23 species of oribatid mites were recorded for the first time from the limestone quarry of Saskhori, and one species (Liacarus oribatelloides) was a new record for the Caucasus fauna. The following indices were analyzed: abundance (N), species diversity (S), Shannon’s diversity index (H), and Pielou’s evenness index (J’). Regarding the obtained results, the highest density of oribatid mites was recorded in the habitat with Shibliak shrubbery (332 inds/m2), while the forest habitat was characterized with the highest value for Shannon’s diversity index (2,64). In the publication, we also provide a detailed morphological description of the newly recorded species L. oribatelloides, with the respective illustration, as no figures are given in its original description. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Research Article text/html info:doi:10.3897/caucasiana.2.e110495 https://doi.org/10.3897/caucasiana.2.e110495 https://caucasiana.pensoft.net/article/110495/ https://caucasiana.pensoft.net/article/110495/download/pdf/ en

Two-headed parthenogenetic lizard embryo from southern Georgia Iankoshvili,Giorgi Tsikolia,Nikoloz Barateli,Natia Gabelaia,Mariam Seropian,Armen Tarkhnishvili,David Axial bifurcation hybridogenous parthenogenesis Squamata Darevskia Caucasiana 2: 199-203 Abstract Visual inspection of several embryos of the parthenogenetic lizard Darevskia armeniaca revealed the presence of an embryo with axial bifurcation (“two-headed”) on the stage of pigmented eyes and plate-like limb buds with a distinct border at the edges. This is the third recorded case of axial bifurcation in D. armeniaca, although two previous cases were mentioned without further discussion. Here the bicephalic embryo is described in detail and the potential reasons are discussed. The analysis of the literature on axial bifurcation in lacertids suggests that this type of developmental disorder may be particularly common in this parthenogenetic form. Hybridization may cause multiple developmental disorders, including incomplete separation of twin embryos; all parthenogenetic Darevskia have a hybrid origin, and this may cause the disorders rather than parthenogenetic reproduction by itself. The hypothesis needs further study with more representative samples of parthenogenetic and sexually reproducing Darevskia. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2023 Short Communication text/html info:doi:10.3897/caucasiana.2.e111452 https://doi.org/10.3897/caucasiana.2.e111452 https://caucasiana.pensoft.net/article/111452/ https://caucasiana.pensoft.net/article/111452/download/pdf/ en

They were collected from shallow and deep waters of the southwestern Caspian Sea using various methods, including beach seining, scuba diving, and deepwater bottom beam trawls. The slope (b) of LWRs ranged from 2.874 for B. baeri, to 3.408 for H. bergi with coefficient of determination higher than 0.918. The b values showed significant differences between the sexes of all species. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2024 Short Communication text/html info:doi:10.3897/caucasiana.3.e118074 https://doi.org/10.3897/caucasiana.3.e118074 https://caucasiana.pensoft.net/article/118074/ https://caucasiana.pensoft.net/article/118074/download/pdf/ en

Which species of water frogs inhabit ponds of the Caucasus? Taxonomic mess with Pelophylax ridibundus species complex Tarkhnishvili,David Todua,Mariami Iankoshvili,Giorgi mitochondrial DNA Pelophylax ridibundus Pelophylax bedriagae water frog taxonomy Caucasiana 3: 31-39 Two nominal species of water frogs of the genus Pelophylax, P. ridibundus and P. bedriagae, are found in Central and Eastern Europe, the Middle East, Western Asia, Western Kazakhstan, and Siberia. So far, the taxonomic status of Pelophylax in most of the Caucasus has remained unknown. Sequencing of the Cytochrome Oxidase 1 mitochondrial gene attributed the frogs throughout Georgia to the P. ‘bedriagae’ lineage, bringing them very close to the specimens from Kazakhstan and Greece. Simultaneously, the current nomenclature of water frogs appears to be formally incorrect since western Kazakhstan, the type locality for P. ridibundus, has frogs genetically closer to nominal P. bedriagae, than to nominal P. ridibundus from Europe. Because there is no evidence that the frogs from Central Europe, Kazakhstan, and the Caucasus, as well as from Anatolia and Iran, are biological species with individual evolutionary pathways, we suggest a conservative approach and synonymize nominal P. bedriagae from most of West Asia with P. ridibundus. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2024 Research Article text/html info:doi:10.3897/caucasiana.3.e117215 https://doi.org/10.3897/caucasiana.3.e117215 https://caucasiana.pensoft.net/article/117215/ https://caucasiana.pensoft.net/article/117215/download/pdf/ en

Successions of terrestrial invertebrate communities during the Tsey Glacier retreat, Central Caucasus Makarova,Olga Antipova,Maria Babenko,Anatoly Bushueva,Irina Chulei,Artemii Golovatch,Sergei Doroshina,Galina Kolesnikov,Vasiliy Mazei,Yuri Makarov,Kirill Palatov,Dmitry Ponomarev,Alexandr Popov,Konstantin Rapoport,Irina Semionenkov,Oleg I. Snegovaya,Nataly Sheftel,Boris I. Tsyganov,Andrey Turbanov,Ilya Zuev,Roman chronosequence climate warming endemic models of succession pioneer species species extinction Caucasiana 3: 41-87 In the Caucasus, the total area taken up by glaciers is known to have reduced by 23% over the last 20 years. This natural experiment allows for additive and replacement models of autogenic succession of biocoenoses within paraglacial landscapes to be tested. A certain risk of the extinction of cryophilic species also exists. However, montane paraglacial successions of invertebrate assemblages have hitherto been studied neither in the Caucasus nor in Russia as a whole. Structural changes of taxocoenoses were traced in a spatial and temporal sequence of ten properly dated paraglacial sites in the Tsey Gorge, North Ossetia − Alania (1–170-years old) among the testate amoebae, earthworms, molluscs, myriapods, mites, spiders, harvestmen, pseudoscorpions, collembolans, and beetles. As the glacier retreats, in place of bare paraglacial wastelands, grassland communities are formed that, after 10–14 years, are replaced by shrub vegetation and, on 30–35-year old surfaces, by forest communities. Most of the invertebrate groups, once “appearing” along a postglacial transect, were recorded from most older plots as well. Yet, their taxocoenoses underwent considerable transformations through increasing (or an increase turning into some decline in beetles) the species diversity and a strong, often complete change in the taxonomic composition and dominance structure. The most considerable transformations were observed at all major vegetation changes. The “appearance” of some groups in the transect was determined not only by dispersion capacities but mainly by the environmental conditions of particular habitats. When comparing the composition of the pioneer postglacial species complex of the study region with that in the mountains of Europe’s south and north, its high-degree regional specificity was noted, sometimes shown at the family level (in spiders). Spatial β-diversity of all larger taxa studied was mainly attributed to turnover (due to “the replacement model” of succession). The general level of change diminished towards the later succession stages. Endemic arthropod species were revealed both in pioneer grassland and developed forest communities. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2024 Research Article text/html info:doi:10.3897/caucasiana.3.e117332 https://doi.org/10.3897/caucasiana.3.e117332 https://caucasiana.pensoft.net/article/117332/ https://caucasiana.pensoft.net/article/117332/download/pdf/ en

Findings from our most recent survey in 2024 revealed a 40% increase in the number of White Stork nesting pairs in settlements previously surveyed during the 2018–2020 census. However, this increase was not statistically significant. The 2024 survey expanded its scope to include 36 additional settlements that had not been surveyed or reported in prior assessments, resulting in the documentation of 55 new nesting pairs within 22 settlements. Among the 23 settlements surveyed in both 2018–2020 and 2024, fluctuations in the number of White Stork nesting pairs were observed in 14 settlements, with a general increase and slight declines noted in four settlements. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2024 Research Article text/html info:doi:10.3897/caucasiana.3.e141157 https://doi.org/10.3897/caucasiana.3.e141157 https://caucasiana.pensoft.net/article/141157/ https://caucasiana.pensoft.net/article/141157/download/pdf/ en

In total, 19 specimens of small mammals were examined, of which 10 gastrointestinal helminth species were detected. Five out of eight specimens of Apodemus uralensis were infected with three nematode species: Heligmosomoides polygyrus, Syphacia obvelata, and Trichuris muris. Notably, the liver of a single individual of A. uralensis was also infected with cestode—Echinococcus multilocularis, (larvocysts) —a novel host record for this parasite in Georgia. All eight exeminated Microtus daghestanicus specimens were infected with both cestode (Paranoplocephala omphalodes and Rodentolepis asymmetrica) and nematode (Heligmosomum costellatum and Syphacia sp.) parasites. Similarly, all three exeminied specimens of Mustela nivalis were infected with cestodes (Versteria mustelae) and nematodes (Molineus patens, Syphacia sp.). For Syphacia sp., M. nivalis is a new host record in Georgia. Only one specimen of A. uralensis was simultaneously infected by two species of nematodes (Syphacia sp., T. muris) and also a single individual of M. nivalis was infected with three species of helminths (V. mustelae, M. patens, Syphacia sp.).

DNA barcoding of some Anura species from Rize Gür,Başak Ergül Kalaycı,Tuğba COI Anura Caucasian biodiversity Caucasiana 4: 15-24 The use of COI barcodes for specimen identification and species discovery has proven to be a functional molecular approach in the study of Anura. In this study, we evaluated the genetic status of Bufo bufo, Hyla orientalis, and Rana macrocnemis from different parts of Rize, Türkiye, using the COI gene marker, a popular method known as DNA barcoding. The Caucasus region is known to host a substantial amount of global biodiversity; however, limited barcoding studies are available for vertebrate taxa within this region. We have submitted all generated sequences to the BOLD data system, with the majority representing the first data from Rize in this database. Our analysis revealed four distinct barcode index numbers belonging to members of three different families. We observed a genetic distance of 0.038 between B. bufo specimens from İyidere and Çamlıhemşin. Within R. macrocnemis, genetic distances ranged from 0.018 to 0.020, and within H. orientalis, they ranged from 0.01 to 0.02. Our findings indicate that COI sequencing is a useful tool for the identification of anuran species present in Rize. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2025 Research Article text/html info:doi:10.3897/caucasiana.4.e144670 https://doi.org/10.3897/caucasiana.4.e144670 https://caucasiana.pensoft.net/article/144670/ https://caucasiana.pensoft.net/article/144670/download/pdf/ en

Distribution, community composition and vulnerability of fish species in the Algeti River Basin (Georgia) Epitashvili,Giorgi Ramazashvili,Giorgi Japoshvili,Bella Mumladze,Levan Artificial barriers Freshwater HPP dam Invasive Reservoirs South Caucasus Caucasiana 4: 45-58 This study presents the first comprehensive survey of fish species’ diversity and distribution in the Algeti River and its reservoir in Georgia, a region within the Caucasus biodiversity hotspot. The research, conducted between 2016 and 2022, identified 19 fish species, including nine native to the Kura River basin and ten introduced or invasive species. The construction of a hydro power plant (HPP) dam in the 1980s and other subsequent anthropogenic activities have significantly altered the river ecosystem, creating distinct upstream, reservoir, and downstream sections with varying fish communities. The study reveals a concerning ongoing impact of anthropogenic factors on the Algeti River's fish fauna and whole ecosystem. The dam impedes fish migration; in addition, pollution, particularly in the mid-downstream section, has led to habitat degradation and a decline in native species. The introduction of non-native species, including predatory and bioturbator species, poses a substantial threat to the native fish populations. Our findings highlight the urgent need for conservation action to mitigate these threats. While the river's headwaters are within a protected area and some species are on the Red List of Georgia, alone these designations are insufficient safeguard. Effective conservation strategies must include stricter enforcement against illegal activities like poaching, as well as better pollution control and habitat management to preserve the Algeti River's biodiversity. This baseline study provides critical data for future research and conservation planning in this ecologically important region. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2025 Research Article text/html info:doi:10.3897/caucasiana.4.e155494 https://doi.org/10.3897/caucasiana.4.e155494 https://caucasiana.pensoft.net/article/155494/ https://caucasiana.pensoft.net/article/155494/download/pdf/ en

Yodelling death – on interspecific aggression in overwintering Black-throated Divers (Gavia arctica) (Aves: Gaviidae) Schröter,Asmus arctic diver arctic loon black-throated loon concurrence ethology food competition Gavia immer overwintering Southern Caucasus ecoregion Caucasiana 4: 81-94 Two cases of interspecific aggression by overwintering black-throated divers directed at great crested grebes Podiceps cristatus, are for the first time described from Georgia and the South Caucasus. In one case, the attack on a pair of great crested grebes had a fatal outcome for one grebe. The reasons for interspecific aggression outside the breeding season and the biological basis of this behaviour is discussed and observations compared with available literature. Due to the anecdotal nature of current knowledge of this puzzling issue no explanation for interspecific aggression per se is provided. The previously published hypothesis that competition for fish prey might play a role is supported. Observed interspecific aggression included adopting the aggressive display postures and performing actions used in territorial defence typical for the black-throated diver and the four larger Gavia species, such as fencing, crouching, bill-dipping, rushing, bow-jumping, and wing-flapping. Calls uttered during attack are a characteristic shortened form of the territorial yodel. A previously unpublished behaviour possibly linked to interspecific aggression of black-throated divers is described. Observation data obtained from 2021-2025 show that the black-throated diver is a regular passage migrant and winter guest at Tbilisi reservoir, emphasising the importance of the reservoir as a migration stop-over for the species in inland Georgia. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2025 Review Article text/html info:doi:10.3897/caucasiana.4.e151878 https://doi.org/10.3897/caucasiana.4.e151878 https://caucasiana.pensoft.net/article/151878/ https://caucasiana.pensoft.net/article/151878/download/pdf/ en

Barn Owl (Tyto alba) Pellet Analysis Reveals Wider Distribution of the Pygmy White-toothed Shrew (Suncus etruscus) in Georgia Kitel,Denis Buknikashvili,Alexander Suncus etruscus barn owl pellet analysis small mammals Georgia distribution Caucasiana 4: 97-104 The pygmy white-toothed shrew (Suncus etruscus), one of the smallest mammals globally, has long been considered rare and poorly studied in Georgia. Traditionally under-recorded due to its small size and elusive behaviour, the species' presence has remained uncertain, with only a few historical or unverified records. In this study, we analysed barn owl (Tyto alba) pellets collected across eastern Georgia between 2023 and 2025 to assess the presence of S. etruscus in the region. From a total of 6,627 prey items extracted and identified, 41 individuals of S. etruscus were found in pellets from 12 different locations in Kakheti and Kvemo Kartli regions. These findings significantly expand the known distribution of the species in Georgia and suggest that it is more common in lowland habitats than previously believed. Given the barn owl’s relatively small foraging range, the occurrence of S. etruscus remains in pellets is a reliable indicator of its local presence. Our results highlight the value of raptor pellet analysis in detecting elusive small mammals and suggest that S. etruscus may have been previously overlooked due to methodological limitations in traditional trapping surveys. This study provides a new foundation for understanding the distribution and habitat preferences of this poorly known species in the Caucasus. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2025 Research Article text/html info:doi:10.3897/caucasiana.4.e162106 https://doi.org/10.3897/caucasiana.4.e162106 https://caucasiana.pensoft.net/article/162106/ https://caucasiana.pensoft.net/article/162106/download/pdf/ en

The diet of Barn Owl (Tyto alba) in Georgia Kitel,Denis Javakhishvili,Zurab Barn Owl diet pellets prey rodents shrews pest control Caucasiana 4: 105-118 The Barn Owl (Tyto alba) has only recently colonized Georgia, yet has rapidly expanded throughout the country's lowland agricultural landscapes. Despite its increasing presence, no prior comprehensive study has examined its diet in Georgia. We analyzed 6627 prey items from Barn Owl pellets collected between 2023 and 2025 at 34 sites across five Georgian regions. After sterilization and dissection, prey remains were identified to the lowest possible taxonomic level and biomass was estimated. The results show that mammals dominate the diet, accounting for 98.6% of all prey items, with rodents (53% by number, 75% by biomass) and shrews (45% by number, 23% by biomass) being the most common prey groups. Other prey included birds, bats, amphibians, reptiles, and invertebrates. Notably, Mus macedonicus, Microtus socialis, and Crocidura spp. were the most frequent mammalian prey. Geographic variation in diet composition was observed, with some sites showing a predominance of shrews. This study provides novel insights into the Barn Owl’s feeding ecology in Georgia and offers the first regional data on several small mammal species, including updated records for Micromys minutus and Suncus etruscus. Given the owl’s preference for rodents, it may serve as a valuable component of sustainable rodent control strategies in Georgian agriculture. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2025 Research Article text/html info:doi:10.3897/caucasiana.4.e162505 https://doi.org/10.3897/caucasiana.4.e162505 https://caucasiana.pensoft.net/article/162505/ https://caucasiana.pensoft.net/article/162505/download/pdf/ en

Occurrence of gregarine parasites of Tenebrio molitor (Coleoptera: Tenebrionidae) in Georgia and Türkiye Yaman,Mustafa Kereselidze,Manana Sağlam Güvendik,Tuğba apicomplexan protists Caucasian coleoptera distribution infection rate Caucasiana 4: 119-124 Gregarines, which belong to the parasitic protozoa, have a variety of negative effects on their hosts. Therefore, it's important to report this pathogen for the first time from a new insect population in Tbilisi, Georgia. Several life stages of the gregarine were found in the midgut lumen of the yellow mealworm, Tenebrio molitor, a pest species of grain and stored food products, which is also gaining attention as a potential sustainable food source. Forty samples from both larvae and adults were dissected, and their intestines were examined under a microscope, demonstrating that both were infected by the parasite. Several life stages of the gregarine parasite were found in the midgut lumens of these mealworms, with the largest trophozoite observed being 67.9 µm in length. Gregarine infection rates in T. molitor larvae were found to be higher than in the adults. Twenty-nine of the 40 examined larvae were infected (72.5%) compared to seven of the 40 examined adults (17.5%). These results suggest that T. molitor larvae are more susceptible to gregarine parasite infection than adults. Our study contrasts with a similar study in Antalya, Turkey, where no gregarine infection was observed in either larval or adult T. molitor. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2025 Research Article text/html info:doi:10.3897/caucasiana.4.e164996 https://doi.org/10.3897/caucasiana.4.e164996 https://caucasiana.pensoft.net/article/164996/ https://caucasiana.pensoft.net/article/164996/download/pdf/ en

Karyotype characteristics and COI gene data of Chironomus degelenus Seisebaev, Bakhtin & Siirin, 2001 (Diptera, Chironomidae) from the Eastern Caucasus (Dagestan) and its relationship with the Nearctic species Chironomus atrella (Townes, 1945) Karmokov,Mukhamed Akkizov,Azamat mitochondrial DNA phylogeny polytene chromosomes Caucasiana 4: 173-194 This study provides new details on the karyotype characteristics, chromosomal polymorphism, and COI gene data of the Dipteran species Chironomus degelenus from the Eastern Caucasus. This is the first record of Ch. degelenus in the Eastern Caucasus (and Russia in General). The Caucasian population of this species shows eight banding sequences and low polymorphism. We discovered a new banding sequence, degC2, in Ch. degelenus. Only arm C showed an inversion polymorphism. There are striking similarities between the polytene chromosome banding patterns of Ch. degelenus and Ch. atrella. Therefore, we propose including Ch. degelenus in the Ch. atrella group of closely related species. Phylogenetic analysis of COI gene sequences reveals two distinct entities referred to as “Ch. atrella”, with a higher-than-average K2P distance of 6.2%. This pattern is attributed to “dark taxa”; genetic information in databases from unknown and taxonomically challenging species. We also discuss the potential link between the emergence of the species Ch. degelenus and Ch. atrella and Pliocene climate changes. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2025 Research Article text/html info:doi:10.3897/caucasiana.4.e165329 https://doi.org/10.3897/caucasiana.4.e165329 https://caucasiana.pensoft.net/article/165329/ https://caucasiana.pensoft.net/article/165329/download/pdf/ en

Succession of soil microarthropods during leaf litter decomposition in two contrasting broadleaved tree stands: A litterbag study Murvanidze,Maka Abuladze,Mariam decomposition feeding mode litterbag Mesostigmata Oribatida soil microarthropods Caucasiana 5: 1-14 Here, we present the results of a litterbag experiment performed in a natural broadleaved forest to study the patterns of microarthropod succession in decomposing litter and the level of adaptation to local vs. spatially distant microhabitats. Ten oak and ten beech leaf-filled, defaunated litterbags were placed under an oak tree, and the same were placed under a beech tree (forty litterbags in total). Five litterbags of each type were collected six and twelve months after the beginning of the experiment, in June and December, respectively. Microarthropod fauna differed between the two sampling events, showing higher diversity and abundance in winter, reflecting the progress of colonization. Microarthropod faunal abundance and species numbers in litterbags filled with oak leaves and placed under the oak trees were significantly higher than those in the other types of litterbags, suggesting the adaptation of the local microarthropod community to this type of litter. The trophic composition of microarthropods showed a higher diversity at the end of the experiment, with increased ratios of predatory and fungivorous taxa, indicating more diverse and easily accessible food resources. Litter dry mass declined continuously for beech litter, while the rate of decline slowed in oak litter between the first and the second sampling events, probably due to the more robust structure of oak leaves compared to beech. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2026 Research Article text/html info:doi:10.3897/caucasiana.5.e169526 https://doi.org/10.3897/caucasiana.5.e169526 https://caucasiana.pensoft.net/article/169526/ https://caucasiana.pensoft.net/article/169526/download/pdf/ en

Avian mortality associated with medium-voltage distribution lines in selected regions of Armenia: results of a pilot survey Harutyunyan,Levon Kovalev,Vitalij Markosyan,Astghik Tarasyan,Narek Aghajanyan,Lusine Gudkov,Mark anthropogenic mortality biodiversity impact bird mortality human–wildlife conflict infrastructure effects South Caucasus utility poles wildlife conservation Caucasiana 5: 41-57 Electrocution on medium-voltage distribution lines is a globally recognized threat to birds, yet data from the South Caucasus remain scarce. In Armenia, the magnitude and spatial distribution of this impact have not previously been assessed through systematic field surveys. This pilot study evaluated bird electrocution in selected regions of the country during the 2024 breeding and autumn migration periods. Surveys covered approximately 114 km of 10 kV overhead power lines (OPLs) (2,071 poles) across Armavir, Ararat, Kotayk, and Shirak provinces. Transects were walked along a 40 m search belt, and all carcasses discovered were documented, with species identification, pole type, and geographic coordinates being recorded. Given resource constraints, following initial surveys, the study prioritised concrete poles over wooden ones as the former were identified as presenting a potentially higher mortality risk. In total, 252 electrocuted birds representing 15 identified species were recorded. Mortality was markedly higher during autumn migration in Shirak (228 cases) than during the breeding season in other surveyed regions (24 cases), although this contrast may reflect both seasonal patterns and regional landscape differences. Corvids and small- to medium-sized diurnal raptors comprised the majority of recorded casualties. Spatial mapping revealed distinct mortality clusters, particularly around Arpi Lake National Park and in open steppe–agricultural landscapes with limited natural perching structures. Informal carcass persistence observations suggested prolonged detectability of large raptor remains. The results indicate that electrocution on medium-voltage lines represents a concentrated and potentially significant source of avian mortality in parts of Armenia, underscoring the need for targeted mitigation and systematic monitoring. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2026 Research Article text/html info:doi:10.3897/caucasiana.5.e188959 https://doi.org/10.3897/caucasiana.5.e188959 https://caucasiana.pensoft.net/article/188959/ https://caucasiana.pensoft.net/article/188959/download/pdf/ en

An Annotated Checklist of the Amphibians and Reptiles of Georgia with DNA Barcoding Data and Taxonomic Remarks Tarkhnishvili,David Iankoshvili,Giorgi Seropian,Armen Kachlishvili,Nino Todua,Mariami Amphibia Reptilia species list taxonomy Caucasiana 5: 59-138 Despite the publication of numerous papers, spanning the period from the 19th century to recent times, that have been devoted to the faunistics and taxonomy of the herpetological fauna of the Caucasus Biodiversity Hotspot, the actual species diversity of the region still remains unclear. Some formally described taxa lack comprehensive validation based on integrative phylogenetic and biogeographic evidence, whereas other nominal species have been questioned or synonymized in subsequent studies. In this paper, we present an annotated checklist of 12 amphibian and 56 reptile species recorded from Georgia, accompanied by taxonomic remarks based on current molecular, morphological, and biogeographic knowledge. Most taxa are represented by DNA barcodes (COI) generated within the Caucasus Barcoding of Life (CaBOL) project and deposited in institutional collections and international databases. We explicitly distinguish between biologically confirmed species, effectively isolated from their closest relatives, and candidate species whose status requires further validation; particularly in cases where contact zones and potential clinal variation remain insufficiently studied. The checklist is supplemented with specimen photographs and generalised distribution maps. Overall, we aim to contribute to a more transparent and critically evaluated taxonomic framework for the herpetofauna of Georgia and the broader Caucasus region. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2026 Checklist text/html info:doi:10.3897/caucasiana.5.e189214 https://doi.org/10.3897/caucasiana.5.e189214 https://caucasiana.pensoft.net/article/189214/ https://caucasiana.pensoft.net/article/189214/download/pdf/ en

A melanistic Eirenis modestus (Martin, 1838) from the Anatolian mainland: first record outside island populations KORKMAZ,Ahmet Gökay Candan,Kamil Hastürk,Ecem Büşra Gül,Serkan Şahin,Mehmet Yıldırım,Elif Kumlutaş,Yusuf Colubridae color polymorphism Gloger's rule thermal melanism Caucasiana 5: 139-146 Melanism is among the most ecologically significant chromatic anomalies reported in squamates, and yet its evolutionary drivers remain a topic of debate. Two principal hypotheses have been proposed: thermal melanism, which holds that darker individuals heat more rapidly in cool climates, and Gloger's rule, which predicts greater melanin deposition in warm, humid environments. Melanistic individuals of Eirenis modestus are a rarely documented phenomenon given the species' characteristically pale dorsal coloration; to date, every previously published record of this dark morph had come from island populations. Here we report the first mainland record of melanism in E. modestus, based on a single specimen collected on 9 May 2024 near Çağman–Demre, Antalya Province, southwestern Türkiye. The individual exhibited entirely black dorsal coloration from head to tail, with greyish-white ventral scales darkening progressively towards the tail. Pholidotic characters were consistent with those previously documented for the species. The Çağman–Demre locality, like all previously reported sites, is characterised by relatively high humidity and a Mediterranean coastal climate, a pattern more consistent with Gloger's rule than with thermal melanism. Further sampling across the Anatolian mainland and adjacent islands is needed to assess the frequency and geographic distribution of this morph. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2026 Short Communication text/html info:doi:10.3897/caucasiana.5.e204607 https://doi.org/10.3897/caucasiana.5.e204607 https://caucasiana.pensoft.net/article/204607/ https://caucasiana.pensoft.net/article/204607/download/pdf/ en

Vegetation of Ski Pistes in the Lesser Caucasus (Bakuriani, Georgia): Species Composition, Functional Traits, and Temporal Dynamics Tedoradze,Giorgi Bakhia,Arsena Jugeli,Tamar Khuskivadze,Dimitri Meghvinetukhutsesi,Nutsa Mikeladze,Giorgi Rasran,Leonid Sikharulidze,Shalva Kikvidze,Zaal biomass disturbance mountain vegetation plant community phytosociology Caucasiana 5: 147-166 Ski piste construction and maintenance are recognised as significant drivers of vegetation change in mountain ecosystems. The Caucasus has a rapidly developing ski tourism and at the same time is an important hotspot of global biodiversity; the impact of this form of land use on vegetation has not yet been studied in the area. We examined plant community structure, species composition and cover, functional-group biomass, and temporal dynamics along an elevation gradient (1,884–2,685 m a.s.l.) spanning montane to alpine zones at the Didveli ski piste within the Bakuriani ski resort (Lesser Caucasus, Georgia). We compared 36 ski piste plots (18 standard-track and 18 eroded) with 25 adjacent undisturbed control plots using ordination (PCA and CCA), cluster analysis, Indicator Species Analysis, and linear mixed-effects models. We analysed the occurrence of 103 species with a frequency ≥ 5 in these plots. PCA clearly separated control plots from disturbed plots along the axis associated with soil depth, species richness, and aboveground biomass. CCA confirmed that species distributions closely followed this human-impact gradient. Cluster analysis identified floristically distinct groups that broadly corresponded to control, track, and eroded conditions. Indicator Species Analysis revealed that undisturbed plots supported typical alpine meadow species (Gentiana septemfida, Bromus variegatus, Veratrum lobelianum), while eroded plots were associated with disturbance-tolerant taxa (Draba hispida, Arctium lappa) and track plots with the compaction-tolerant grass Calamagrostis pseudophragmites. Mean aboveground biomass on control plots (2,526 kg ha–1) was 2.1–3.0 times higher than on track (1,175 kg ha–1) and eroded plots (833 kg ha–1). Graminoids and forbs declined sharply under disturbance, whereas legume biomass was resilient across all land-use types, likely owing to nitrogen-fixation capacity. Temporal monitoring (2020–2023) showed stable or increasing biomass on control plots but limited and short-lived recovery on piste plots. These findings demonstrate that ski piste development substantially reduces biodiversity and productivity in the Caucasus Mountain grasslands and underlines the need for targeted restoration and sustainable management strategies. info:eu-repo/semantics/altIdentifier/eissn/2667-9809 info:eu-repo/semantics/openAccess CC BY 4.0 Pensoft Publishers 2026 Research Article text/html info:doi:10.3897/caucasiana.5.e207119 https://doi.org/10.3897/caucasiana.5.e207119 https://caucasiana.pensoft.net/article/207119/ https://caucasiana.pensoft.net/article/207119/download/pdf/ en
