Abstract

Euroazijski ris (Lynx lynx) reintroduciran je u Sloveniju i Hrvatsku 1973. godine sa slovačkih Karpata. Veličina današnje populacija risa u Hrvatskoj se procjenjuje na 30 do 60 jedinki. Kod risa se uzorci na krznu mogu javljati u obliku pjega i rozeta, prema čemu je 95 obrađenih fotografija krzna svrstano u četiri tipa: krzno s velikim točkama, malim točkama, rozetasto krzno te jednolično krzno bez uzoraka. Zastupljenost pojedinog tipa krzna nije bila specifična za određene dobne skupine. Usporedbom rezultata istraživane populacije s podatcima za karpatsku (izvorne) populaciju zaključeno je da ne postoji povezanost u raspodjeli tipova krzna, čemu je pridonijela smanjena genska raznolikost hrvatske populacije, te činjenica da se ista razvijala izolirano u posebnom staništu. Objektivnom metodom u računalnom programu dobiven je broj, gustoća i raspored točaka na krznu, iz čega je zaključeno da je kod svih tipova područje stražnje noge najbogatije uzorcima dok su na trupu manje zastupljeni. Dobiveni rezultati bili su u sukladnosti s podatcima ostalih autora, koji su rezultate dobivali subjektivnom metodom promatranja i prebrojavanja uzoraka.

Abstract (english)

Eurasian lynx (Lynx lynx) was reintroduced to Slovenia and Croatia in 1973 from the Slovakian Carpathian Mountains. Today lynx population in Croatia is estimated at 30 to 60 individuals. Lynx fur is characterized by spots and rosettes, while 95 photographs of lynx fur analyzed in this research were divided into four categories: fur with large spots, small spots, fur with rosettes and uniformed fur without any pattern. Frequency of each type of fur was not specific for any age group. There is no similarity among the frequency of fur patterns in lynx from Croatia and Carpathian lynx population, probably as a result of lower genetic variability of Croatian lynx population and the fact that these two populations evolved in separate habitats. Number, density and spot pattern for each lynx fur were analyzed with software. Results revealed that hind legs had the highest frequency of spots in each fur category. This is according to results gained by other authors which used subjective methods and analyzed the furs by themselves not buy using computer programs.
