 | For thousands of years, human beings have relied on commodity barter as an essential aspect of their lives. It is the behavior that allows specialized professions, as one individual gives up some of what he has reaped to exchange with another for something different. In this way, both individuals end up better off. Despite the importance of this behavior, little is known about how barter evolved and developed. ...> Full Article |
 | Monkeys living on an island without big cat predators do not show any particular alarm when recorded tiger growls are played to them, according to research by a UC Davis graduate student. The pig-tailed langurs do, however, flee in a hurry from the sound of human voices. ...> Full Article |
 | With the aid of various alarm calls the Siberian jay bird species tells other members of its group what their main predators-hawks-are doing. The alarm calls are sufficient for Siberian jays to evince situation-specific fleeing behaviors, which enhances their chances of survival. This discovery, being published by Uppsala University researcher Michael Griesser in the journal Current Biology, shows for the first time that animals can assess and communicate about the behavior of predators. ...> Full Article |

 | Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones. When seen in the lab, they are nothing like the long upper arm bones of any other mammal, says Samantha Hopkins, a paleontologist at the University of Oregon. ...> Full Article |
 | When resources are scarce, who you know and where you're positioned on the social totem pole affects how far you'll go to search for food. At least that's the case with African elephants, according to a study led by ecologists at the University of California, Berkeley, who collaborated with researchers at Save the Elephants, a non-profit research organization based in Kenya, and at the University of Oxford in England. ...> Full Article |
 | Scientists from the University of Exeter have shown that birds with higher stress levels adopt bolder behaviour than their normally more relaxed peers in stressful situations. The research team studied zebra finches, which had been selectively bred to produce three distinct types - 'laid-back', 'normal' and 'stressed' - based on their levels of stress hormone. The group was surprised to find that the 'stressed' birds were bolder and took more risks in a new environment than the group that was usually more laid-back. Their findings are published today (26 October) in the journal Hormones and Behaviour. ...> Full Article |
 | Research by the University of St Andrews shows that chimpanzees vary their screams depending on the severity of the attack and that they can exaggerate the nature of the attack, but only if higher ranking group members are in the audience. The way they scream provides nearby listeners with important cues about the nature of the attack. ...> Full Article |
