Introduction
I am broadly interested into biodiversity of the Caucasus biodiversity hotspot. This includes biodiversity inventory (including DNA barcoding technology), invasive species, systematics, community ecology, pylo- and biogeography etc. At some extent, I am also involved in a studies from the fields of conservation biology. As a model taxa I am mostly focused on several invertebrate taxa (such as molluscs, mites, crustaceans, etc).

Article
Aquatic invasions are one of the major threats for freshwater ecosystems. However, in developing countries knowledge of biological invasions essential for the implementation of appropriate legislation is often limited if not entirely lacking. In this regard, the identification of potentially invasive non-native species by risk screening, followed b...
Article
Full-text available
Electronic decision-support tools are becoming an essential component of government strategies to tackle non-native species invasions. This study describes the development and application of a multilingual electronic decision-support tool for screening terrestrial animals under current and future climate conditions: the Terrestrial Animal Species I...

This study provides the first attempt to investigate the molecular diversity of South Caucasian freshwater molluscs (Mollusca, Gastropoda) and lay down the first bricks to build up a DNA-barcode library. In total 289 CO1 barcode sequences were obtained from 34 morpho-species belonging to 24 molluscan genera and 10 families that represent nearly 30%...
Article
Full-text available
Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals and the mobilisation of substantial resources. While the reasons are varied, investments in both research and conservation of freshwater biodiversity lag far behind those in the terrestrial and marine realms. Inspired by a global...

Chromosome number data on the Hygromiidae (Gastropoda: Stylommatophora) are summarized and reviewed briefly in the context of the phylogeny of the family. In hygromiids, the haploid chromosome numbers range from 21 to 26. It is supposed that n = 21 is the ancestral chromosome number in the family. The modal haploid number for Hygromiidae is 23. Des...

The Caucasus region is a meeting point for culture and nature, lying at the nexus of Europe, the Middle East, Central Asia, and Africa, and identified as one of 36 global biodiversity hotspots. The Republic of Georgia, the center of the Caucasus biodiversity hotspot, encompasses a geographically diverse landscape inhabited by a remarkable, endemic,...

The South Caucasus (SC) region is recognized for its high biological diversity and various endemic animal taxa. The area has experienced many fish introductions over the years, but the overall information about non-native fishes in the three SC countries, Armenia, Azerbaijan, and Georgia did not exist. Although these three countries belong to the K...
Article
Full-text available
The Serrulinini, a small relict group of clausiliids occurring in coastal regions of the Black and Caspian Seas and the Caucasus, are currently classified within the Phaedusinae, however paraphyletic origin of the Serrulinini is also widely debated with Pontophaedusa funiculum (Mousson) being most phylogenetically distinct from other taxa. As life...
Article
Full-text available
Several taxa that are distributed in the Caucasus and/or the adjacent Pontic Mountains also have representatives in the East Mediterranean region. These disjunctions could have been caused by long‐distance dispersal or be the result of extinctions in Central Anatolia caused by the aridification of the Anatolian Plateau during the Pliocene. We studi...

The diversity and distribution of freshwater molluscs is poorly studied in the Republic of Georgia, due to the scarcity of field studies during the last 50 years. Here, we present the results of the first concerted investigation of freshwater mollusc biodiversity in the Javakheti Highlands, in the southern, mountainous region of Georgia. In total,...
Article
Oribatid mite diversity was investigated in the most understudied region of Georgian South-Eastern Caucasus – open arid ecosystems, which are under heavy natural and anthropogenic disturbance. Field sampling was performed in three geographical units and in each unit three types of ecosystems with different disturbance classes were studied: (1) Arab...

Environmental changes due to non-native species introductions and translocations are a global concern. Whilst understanding the causes of bioinvasions is important, there is need for decision-support tools that facilitate effective communication of the potential risks of invasive non-native species to stakeholders.

The phylogeny of European crayfish fauna, especially with respect to Eastern European species, is still far from being completely resolved. To fill this gap, we analysed most of the European crayfish species focussing on the phylogenetic position of the endemic crayfish Astacus colchicus Kessler, 1876 inhabiting Georgia. Three mitochondrial and one...

Georgia is a country of great diversity of freshwater fish species that is facilitated due to the landscape diversity and richness of water resources. As an area of global biological importance, measuring biodiversity and the conservation of species is a significant issue. Recent taxonomic research found 96 freshwater fish species, from which sever...

The dominance of sex in Metazoa is enigmatic. Sexual species allocate resources to the production of males, while potentially facing negative effects such as the loss of well-adapted genotypes due to recombination, and exposure to diseases and predators during mating. Two major hypotheses have been put forward to explain the advantages of parthenog...
