Caucasiana is an international peer-reviewed open-access, free-of-charge online journal that covers all research branches related to biodiversity in the Caucasus region and adjacent areas. The journal is a successor of the "Proceedings of the Institute of Zoology", which was the Georgian zoological print only journal for a long time. The Caucasiana was, however launched (thanks to an effort made by Ilia State University (Georgia) and Pensoft publishers) in order to widen and enhance biodiversity research and publishing in the poorly studied Caucasus biodiviersity hot-spot and surroundings. 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.
