Foundations of gregariousness: a dispersal polymorphism among the planktonic larvae of a marine invertebrate.

Theory predicts that selection should favor genotypes that can vary their tendency to disperse in habitats that are spatially or temporally variable or those that remain near their carrying capacity. Although many marine habitats appear to fit these criteria, confirmed examples of dispersal polymorphism among marine invertebrates are exceedingly rare. Competent larvae of the gregarious tubeworm...

Sex differences in human gregariousness

Research on human sociality rarely includes kinship, social structure, sex, and familiarity, even though these variables influence sociality in non-human primates. However, cross-cultural ethnographic and observational studies with humans indicate that, beginning after age 5 years, males and females form differing social structures with unrelated individuals in a community. Specifically, compar...

Gregariousness, Interactive Jobs and Wages

Gregariousness is an important aspect of human life with implications for labour market outcomes. The paper examines, to the best of our knowledge for the first time for Germany, gregariousness and social interaction at the workplace and associated wage differentials. Our empirical findings with samples from the German Socio-Economic Panel (SOEP) demonstrate that gregarious people more often wo...
