No sex-biased dispersal in a primate with an uncommon social system-cooperative polyandry. [PDF]
, 2014 An influential hypothesis proposed by Greenwood (1980) suggests that different mating systems result in female and male-biased dispersal, respectively, in birds and mammals.

Population genetic structure and direct observations reveal sex-reversed patterns of dispersal in a cooperative bird [PDF]
, 2014 Sex-biased dispersal is pervasive and has diverse evolutionary implications, but the fundamental drivers of dispersal sex biases remain unresolved. This is due in part to limited diversity within taxonomic groups in the direction of dispersal sex biases,

Perspectives on the Effect of Incubation Temperature on Pine Snake Hatchlings
Ethology, EarlyView.Effect of timing of egg‐laying and incubation temperature on the possible phenology of events for early egg‐laying females (laying June 15, the earliest laying date), the mid‐laying date (July 4), and late egg‐laying females (July 17, the latest egg‐laying date). Based on data from many papers.

The evolution of female social relationships in nonhuman primates [PDF]
, 1997 Considerable interspecifc variation in female social relationships occurs in gregarious primates, par- ticularly with regard to agonism and cooperation be- tween females and to the quality of female relationships with males.

Collectivism–Individualism, Family Ties, and Philopatry [PDF]
, 2014 As predicted by the parasite-stress theory of values, variation in parasite stress correlated with collectivism–individualism across nations, USA states, and indigenous societies. In regions with high adversity of infectious diseases, human cultures are characterized by high collectivism, whereas in regions of low parasite stress cultures are highly ...

Fish and Fisheries, EarlyView.ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.

Variable social organization and breeding system of a social parrot revealed by genetic analysis
Ibis, EarlyView.Social organization and contributions to reproduction vary widely within and between species that breed in groups. Such variation often arises from the process of group formation, which drives patterns of relatedness and hence the degree of social conflict and co‐operation between group members.
