Male vulnerability explains the occurrence of sexual cannibalism in a moderately sexually dimorphic wolf spider.

abstract：:Unrestrained, naı̈ve cats (Felis silvestris catus) (n=48: 28 males and 20 females), living in a natural domestic environment, were studied for paw preferences using a food reaching test. A total of 46% were right-preferent, 44% were left-preferent and 10% were ambilateral. 60% of the cats in our sample used one paw 10...

abstract：:It has been shown that duration of tonic immobility (TI) reflects predation risk and levels of fearfulness. Since the chances of escaping predation are higher in larger groups, birds from these groups should have shorter TI duration. On the other hand, increased competition between birds in larger groups might lead to...
