Contribution to the knowledge of distribution and diversity of lacertid lizards in Serbia

Abstract

In this study, we present updated distributional data for all Serbian lacertids, having taken into account the available previously published information, and the so far unpublished authors' field records and evidence from other sources. According to our current knowledge, eight lacertid species inhabit Serbia. Analysis of lacertid diversity within the country showed that biogeographic regions with highest species diversity are Metohija (eight species) and Kosovo (seven species). Regions in Serbia are mutually similar concerning lacertid faunas (average Bray-Curtis dissimilarity index is 0.82). Comparative analysis of lacertid faunas among all Balkan countries showed that Serbian lacertid fauna is the most similar to those of Albania and the FYR of Macedonia, and then to faunas of Romania and Bulgaria. Zoogeographic analysis showed that Serbian lacertids belong to three distinct chorotypes, with the East-Mediterranean being the richest (four species). Generally, diversity of lacertids in Serbia is most strongly determined by topographic diversity, habitat heterogeneity, and climatic peculiarities, with the inflow of the sub-Mediterranean climate along several river valleys in the south being especially important. This paper is intended to serve as a basis for further research, since data on distribution of lacertid species in Serbia are far from complete, with large distributional gaps of recorded species and with unconfirmed presence of two species.
