New PNAS Paper


A new study by Shark Bay researchers, published in Proceedings of the National Academy of Sciences, shows that female calving success is better explained by their social bonds than their genes. The study also looks at the interaction between social and genetic factors and finds that the interaction of the two is the most powerful way to explain why some dolphin females are successful at raising calves and why others are not. Who your friends or associates are matters, but it matters even more between non-relatives than relatives. This is the first animal study to examine the interaction of genetic and social impacts on reproduction in a wild population.
