Low cognitive competence as a vulnerability factor for behavioral despair in rats.

abstract：:Many animal species hoard food by carrying it to their home area. In this experiment we evaluated the interaction between persistent (formalin) pain and food-hoarding behaviour. A food-hoarding apparatus, consisting of a home cage connected with an alley at the end of which were placed food pellets, was used to test (...

abstract：:Aposematic prey advertise their toxicity to predators using conspicuous warning signals, which predators learn to use to reduce their intake of toxic prey. Like other types of prey, aposematic prey often differ in body size, both within and between species. Increasing body size can increase signal size, which make lar...
