Abstract

Žuta poljarica, Dolichophis caspius (Gmelin, 1789) ugrožena je vrsta koja u Hrvatskoj dolazi u izoliranim i odvojenim populacijama na tri poznata lokaliteta. Rasprostranjena je na kopnu u Baranji te na otoku Olibu i Lastovskom otočju. Do sad nisu rađena sustavna istraživanja ove vrste u Hrvatskoj i stanje populacija nije poznato. Cilj ovog istraživanja bio je utvrditi morfometrijske i merističke značajke te razlike po dobi, spolu i lokalitetu populacija žute poljarice u Hrvatskoj. Ukupno je ulovljeno 116 jedinki žute poljarice na sva tri poznata lokaliteta. Premjereno je 14 morfometrijskih, a izbrojane tri merističke značajke te je izvagana masa jedinki. Utvrđeno je postojanje razlika u morfometrijskim i merističkim značajkama između populacija te između mužjaka i ženki unutar populacija. Mužjaci su veći od ženki unutar populacije, a najveći mužjaci, kao i ženke, su u Baranji, dok su najmanji na Lastovskom otočju. Mužjaci imaju manji broj trbušnih ljusaka od ženki unutar populacije, ali imaju veći broj podrepnih. Mužjaci i ženke s Lastovskog otočja imaju više trbušnih i podrepnih ljusaka nego mužjaci i ženke iz Baranje.

Abstract (english)

The Caspian whip snake, Dolichophis caspius (Gmelin, 1789) is an endangered species that lives in Croatia in three isolated and separated populations in three known localities. It is found on the mainland in Baranja and on the islands of Olib and Lastovo archipelago. So far, no systematic research has been carried out in Croatia and the population status is unknown. The aim of this study was to determine the morphometric and meristic characteristics and differences in age, sex, and locality of the populations. Altogether, 116 individuals were captured within three known sites in Croatia. Fourteen morphometric, three meristics characteristic and mass of individuals were recorded. Differences in morphometric and meristic characteristics between populations and between males and females within the populations have been confirmed. Males are larger than females within a population, and the largest males and females are in Baranja while the smallest are on Lastovo archipelago. Males have a smaller number of ventral scales than females within a population but have a greater number of subcaudal scales. The males and females of Lastovo archipelago have more ventral scales and subcaudal scales than males and females from Baranja.
