Extensive sampling across an altitudinal span of 200 to 1,100 m a. in the study area revealed 62 localities with populations of both or either species. At 11 of these localities (18%) species occurred in syntopy, at 42 locations (68%) only common wall lizards were found, while at 9 locations (14%) only Horvath%s rock lizards were recorded. Both species occurred across the entire altitudinal span but exhibited an opposite pattern of relative abundances and frequencies, which increased with increasing altitude in Horvath%s rock lizard and with decreasing altitude in common wall lizard. The habitat use of common wall lizard was more general (it was found in seven habitat types) than Horvath%s rock lizard that was registered only in three habitat types with rocksV raziskavi smo pridobili skupno 62 novih podatkov o razširjenosti dveh vrst kuščaric na Kočevskem: za pozidno kuščarico (Podarcis muralis) in velebitsko kuščarico (Iberolacerta horvathi). Od vseh 62 lokacij sta se vrsti pojavljali sintopično na 11 lokacijah (18 %), na 42 lokacijah (68 %) je bila zabeležena le pozidna kuščarica, na 9 lokacijah (14 %) pa izključno velebitska kuščarica. Obe vrsti sta na Kočevskem razširjeni čez celotni višinski gradient, ki se razteza med 200 m n.m. v dolini reke Kolpe do 1100 m n.m. na najvišjih vrhovih planot. Vendar pa se vrsti pojavljata v višjih relativnih gostotah na različnih nadmorskih višinah, in sicer je velebitska kuščarica pogostejša v višjih legah, pozidna kuščarica pa v nižjih. Kar zadeva rabo prostora, smo ugotovili, da je pozidna kuščarica nagnjena bolj k splošni rabi prostora kot velebitska kuščarica. Pozidna kuščarica je bila najdena v sedmih različnih habitatnih tipih, medtem ko je bila velebitska kuščarica najdena le v treh, in sicer: v naravnih in umetnih ostenjih in presvetljenem gozduTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaNacionalni inštitut za biologijo
