Validity of the prey-trap hypothesis for carnivore-ungulate interactions at wildlife-crossing structures.
Wildlife-exclusion fencing and wildlife-crossing structures (e.g., underpasses and overpasses) are becoming increasingly common features of highway projects around the world. The prey-trap hypothesis posits that predators exploit crossing structures to detect and capture prey. The hypothesis predicts that predation events occur closer to a highway after the construction of fences and crossing s...
متن کاملPerformance indices to identify attributes of highway crossing structures facilitating movement of large mammals
Studies assessing the efficacy of wildlife crossing structures often lead to spurious results because of their failure to address masking effects of confounding variables. Confounding variables include variation in human activity, density of crossing structures along the highway corridor, and equality of species’ perceived access to each crossing structure. We investigated these issues for wide...
متن کاملStable isotopes reveal rail-associated behavior in a threatened carnivore
Human-wildlife conflict is a leading cause of adult mortality for large carnivores worldwide. Train collision is the primary cause of mortality for threatened grizzly bears (Ursus arctos) in Banff National Park. We investigated the use of stable isotope analysis as a tool for identifying bears that use the railway in Banff. Rail-associated bears had higher δ(15)N and δ(34)S values than bears sa...
متن کاملBlack bear (Ursus americanus) survival and demography in the Bow Valley of Banff National Park, Alberta
We studied survival and demography of black bears, Ursus americanus, in Banff National Park (BNP) from 1994 to 2000 to test the efficacy of National Park protection. We monitored 25 radiocollared bears an average of 1.9 years each for a total of 51.8 bearyears. Eighty-two percent of all mortality {n= \\) was human-caused, composed of highway mortality (36%), management mor tality (27%) and man...

organisation KuzeyDog ̆a has for the past few years led studies of the carnivores in northeastern Turkey. With the first wolf-tracking project in Turkey, the research showed that these predators move much more widely than the confines of the protected areas. Within just two months they covered an area that was 13 times larger than the national park where they were caught and fitted with GPS/GSM ...
