Data from: Facial width predicts male fitness and rank but not survival in Second World War Finnish soldiers

John Loehr & Robert B. O'Hara
We investigated fitness, military rank and survival of facial phenotypes in large scale warfare using 795 Finnish soldiers who fought in the Winter War (1939-40). We measured bizygomatic facial width vs. height - a trait known to predict aggressive behaviour in males - and assessed whether facial morphology could predict survival, lifetime reproductive success (LRS) and social status. We found no difference in survival along the phenotypic gradient, however, wider-faced individuals had greater LRS, but...

Data from: Social learning of migratory performance

Thomas Mueller, Robert B. O’Hara, Sarah J. Converse, Richard P. Urbanek & William F. Fagan
Successful bird migration can depend on individual learning, social learning, and innate navigation programs. Using 8 years of data on migrating whooping cranes, we were able to partition genetic and socially learned aspects of migration. Specifically, we analyzed data from a reintroduced population wherein all birds were captive bred and artificially trained by ultralight aircraft on their first lifetime migration. For subsequent migrations, in which birds fly individually or in groups but without ultralight escort,...
