Caucasiana is an international peer-reviewed, open-access, and free-of-charge online journal that covers all research branches related to biodiversity in the Caucasus region and adjacent areas. Thanks to an effort made by Ilia State University (Georgia) and Pensoft Publishers, the Caucasiana was launched in 2022 in order to widen and enhance biodiversity research and publishing in the poorly studied Caucasus biodiversity hotspot. While there is no bias with regards to the branches of biodiversity sciences or manuscript size, the journal only considers manuscripts related to the biodiversity of the Caucasus and adjacent areas, given sufficient novelty and high quality of research.
