Inferences about food location in three cercopithecine species: an insight into the socioecological cognition of primates.

abstract：:The ability to compute probability, previously shown in nonverbal infants, apes, and monkeys, was examined in three experiments with pigeons. After responding to individually presented keys in an operant chamber that delivered reinforcement with varying probabilities, pigeons chose between these keys on probe trials. ...

Intraspecific signaling by male cuttlefish has been well documented but studies on signaling by females are lacking.

In response to an approaching threat, a chameleon on a vertical pole moves so as to keep itself away from the threat. In so doing, it shifts between monocular and binocular scanning of the threat and of the environment. We analyzed...
