Experiment 2 used the same methodology with 18- to 36...

Parasitism is widely viewed as the primary cost of sociality and a constraint on group size, yet studies report varied associations between group size and parasitism. Using the largest database of its kind, we performed a meta-analysis of 69 studies of the relationship between group size and parasite risk, as measured by parasitism and immune defenses.

متن کاملTransforming potential is detectable in arteriosclerotic plaques of young animals.
The carcinogen-treated cockerel is a model for studying the early stages of arteriosclerotic plaque development. Carcinogen administration accelerates arteriosclerotic plaque development in cockerels, and transforming elements are present in DNA from advanced human plaques. In this study, we asked whether transforming elements could also be detected at early stages of plaque development in cock...
