Abstract:Doživke spadajo med eno izmed najbolj ogroženih skupin vretenčarjev. Velik del krivde za to gre pripisati človeku. Ta v naravni habitat dvoživk in tudi drugih živali posega na več različnih načinov. Izgradnja cest in cestni promet je eden izmed vzrokov, ki lahko drastično vpliva na lokalno populacijo dvoživk. Pri dvoživkah ta največkrat prečka pot selitve do mrestišč. Takšno točko, kjer cesta prečka selitveno pot in kjer prihaja do množičnih povozov imenujemo črna točka. Ozaveščenost ljudi o ogroženosti dvoživk narašča, zato je tudi informacij o črnih točkah in akcij reševanja dvoživk vedno več. Namen diplomske naloge je popis vrst in število živih dvoživk, ki prečkajo cesto, se ustavijo ob zaščitni mreži in uporabljajo podhode na cestnem odseku Cankova-Kuzma ob Ledavskem jezeru. V raziskavi sem ugotovila, da je na raziskovalnem področju prisotnih šest vrst dvoživk: navadna krastača (Bufo bufo), rosnica (Rana dalmatina), sekulja (Rana temporaria), zelena žaba (Phelophylax spp.), zelena rega (Hyla arborea), navadni pupek (Lissotriton vulgaris) in veliki pupek (Triturus carnifex). Ugotovila sem, da se je število dvoživk, ki se ustavijo ob mreži in ki uporabljajo podhode povečalo, v letu 2005 sem ob mreži popisala 3934 dvoživke v letu 2011 pa kar 6294. Prav tako sem popisala večje število dvoživk, ki za prečkanje ceste uporabljajo podhode. V letu 2005 je podhode uporabilo 1483 dvoživk, v letu 2011 pa 1706 dvoživk. Na podlagi teh rezultatov lahko sklepam, da začasna zaščitna mreža in podhodi pomagajo pri ohranitvi populacije.

Title:Attention, amphibians on the road - Monitorin of amphibians on the black spot along the lake Ledavsko jezero
Abstract:Amphibians (Amphibia) are among one of the most endangered species in the world due to man’s interference affecting their natural habitat in several different ways. Road building can dramatically hurt the population because it usually intersects the migration route to the breeding waters. Such a spot, where a road crosses a migration route resulting in mass amphibian road mortality, is called a »black spot«. Awareness about the threats to amphibians is rising thus making the information about the ‘black spots’ and ways of rescuing the amphibians to be on the rise as well. The purpose of this graduation thesis is to list the species and the number of live amphibians that cross the road, stop at the protective net and use passages at the road section Cankova – Kuzma by the lake Ledavskojezero and determine the effect of the nets on the number of the amphibians between the years 2005 and 2011. The results showed that there are six different species present in the area around the lake Ledavsko jezero: European Common Toad (Bufobufo), Agile Frog (Rana dalmatina), European Common Frog (Rana temporaria), Water Frog (Phelophylax spp.), European Tree frog (Hylaarborea), Smooth Newt (Lissotriton vulgaris) and the Italian Crested Newt (Trituruscarnifex). The results also showed that the number of amphibians which stopped at the net increased from 3934 in the year 2005 to 6294 in the year 2011. Moreover, the number of the amphibians which used the passages to cross the road increased from 1483 in the year 2005 to 1706 in the year 2011. Based on these results I can conclude that the temporary protective net along with the passages help to maintain the population of the amphibians
