In mammalian predators, prey size typically increases with body size, such that most carnivores weighing .21.5 kg specialize on prey weighing 45% of their own mass. By hunting in packs, endangered African wild dogs (Lycaon pictus) are able to feed primarily on ungulates weighing .100% of their own individual mass and, in most populations, wild dogs specialize on such large prey. However, we sho...

Bovine tuberculosis (bTB) caused by Mycobacterium bovis or M. caprae has recently (re-) emerged in livestock and wildlife in all countries bordering Switzerland (CH) and the Principality of Liechtenstein (FL). Comprehensive data for Swiss and Liechtenstein wildlife are not available so far, although two native species, wild boar (Sus scrofa) and red deer (Cervus elaphus elaphus), act as bTB res...

Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an "escape" from predation, but trade-offs can also occur at finer spatial scales. Previous authors suggest that ungulates will avoid predation risk at the largest scale, although few studies have ...

Juvenile mortality of inbred young was higher than that of noninbred young in 15 of 16 species of captive ungulates. In 19 of 25 individual females, belonging to ten species, a larger percentage of young died when the female was mated to a related male than when she was mated to an unrelated male.

Aim Global warming is threatening species survival worldwide. Cold-adapted montane ungulates may be among the first to affected by global warming. Here, we investigate behavioural thermoregulation hypothesis that buffer effects of climate through adjustment. Location Foping National Nature Reserve (FNNR) on southern slopes Qinling Mountains, Shaanxi, China. Methods We used infrared camera traps...
