Infant handling in wild Cebus capucinus: testing bonds between females?

Article Abstract:

Research undertaken among wild Cebus capucinus monkeys has failed to support a number of widely held hypotheses about infant handling (IH). Parous females undertook a large proportion of all IH, and parous females engaged in more IH than did nulliparous females when juvenile females were individually recognizable. This indicates that practice for motherhood is not the only purpose of IH. It was possible to obtain partial support for the prediction from the bond-testing hypothesis that mothers will tolerate longer IH episodes from females that they had groomed at higher rates before the birth of their child.

Guidelines for the capture, handling, and care of mammals as approved by the American Society of Mammalogists

Article Abstract:

The American Society of Mammalogists has issued an updated and expanded version of its 1987 guidelines on the capture, handling and care of mammals for research. These guidelines include specimen collection methods, techniques for sampling tissues from live mammals, caring for dependent offspring, euthanasia methods, transportation of captured mammals and the maintenance of wild-caught mammals in captivity.

Experimental demonstration of an Allee effect in American ginseng

Article Abstract:

Studies done for reproductive limitation due to small population size using 4-year-old cultivated plants are presented. Results reveal that it is unreasonable to assume that reproductive parameters will remain constant when populations are reduced by harvest. The detrimental effects of harvest on population viability can be greater with the inclusion of Allee effects.
