Social transmission of Pavlovian fear: fear-conditioning by-proxy in related female rats.

abstract：:Assessing the amount of rivals is crucial to optimally adjust investment into a contest. If laboratory animals show numerical abilities, little is known about the ecological implications particularly in young animals. The two to nine barn owl (Tyto alba) siblings vocally compete for priority of access to food resource...
