Črna točka za dvoživke na cestnem odseku Račeva-Smrečje pri Žireh : diplomsko deloGartnar, AnaDvoživke (Amphibia) veljajo za ogroženo živalsko skupino vretenčarjev. Vzroke za njihovo zmanjšanje populacij lahko iščemo tudi v posegih človeka v okolje. Z urbanizacijo in izgradnjo infrastrukture ... prihaja do fragmentacije naravnih prebivališč dvoživk. V zadnjih leti opažamo bistven dvig ozaveščenosti ljudi o pomenu dvoživk. Vendar se še vedno zasipavajo "nepotrebne" mlake, močvirja itd. Drugi vzrok ogroženosti dvoživk je povezan s povozi na cestah. Mreža cest je vedno gostejša in dejstvo je, da se danes zaradi večje gostote prometa na cestah povozi mnogo več dvoživk. Namen diplomskega dela je popisati vrste ter število živih in povoženih dvoživk, ki prečkajo cesto na območju cestnega odseka Račeva-Smrečje, in sicer v okolici Račevskega jezera v dolžini 500 m. Rezultati moje raziskave so pokazali, da so v okolici Račevskega jezera prisotne tri vrste dvoživk: sekulja (Rana temporaria), navadna krastača (Bufo bufo) in navadni pupek (Triturus vulgaris). Ugotovila sem, da je razmeroma velik delež dvoživk žrtev prometa. Od skupno 6956 dvoživk je povoženih 1245 živali, kar predstavlja 18 % spolno zrelih živali. Na podlagi tega lahko preiskovani cestni odsek označim kot črno točko.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Maribor : [A.
