Social relationships have profound effects on health in humans and other primates, but the mechanisms that explain this relationship are not well understood. Using shotgun metagenomic data from wild baboons, we found that social group membership and social network relationships predicted both the taxonomic structure of the gut microbiome and the structure of genes encoded by gut microbial species. Rates of interaction directly explained variation in the gut microbiome, even after controlling for diet, kinship,...

Data from: Quantification of mesocosm fish and amphibian species diversity via eDNA metabarcoding

Nathan T. Evans, Brett P. Olds, Cameron R. Turner, Mark A. Renshaw, Yiyuan Li, Christopher L. Jerde, Andrew R. Mahon, Michael E. Pfrender, Gary A. Lamberti & David M. Lodge
Freshwater fauna are particularly sensitive to environmental change and disturbance. Management agencies frequently use fish and amphibian biodiversity as indicators of ecosystem health and a way to prioritize and assess management strategies. Traditional aquatic bioassessment that relies on capture of organisms via nets, traps and electrofishing gear typically has low detection probabilities for rare species and can injure individuals of protected species. Our objective was to determine whether environmental DNA (eDNA) sampling and metabarcoding analysis...

Data from: Sequential divergence and the multiplicative origin of community diversity

Glen R. Hood, Andrew A. Forbes, Thomas H. Q. Powell, Scott P. Egan, Gabriela Hamerlinck, James J. Smith & Jeffrey L. Feder
Understanding how new life forms originate is a central question in biology. Population divergence is usually studied with respect to how single lineages diverge into daughter taxa. However, populations may not always differentiate in isolation; divergence of one taxon could create new niche opportunities in higher trophic levels, leading to the sequential origin of many new taxa. Here, we show that this may be occurring for three species of parasitoid wasps attacking Rhagoletis fruit flies....

Data from: Rapid and repeatable shifts in life-history timing of Rhagoletis pomonella (Diptera: Tephritidae) following colonization of novel host plants in the Pacific Northwestern United States

Monte Mattsson, Glen R. Hood, Jeffrey L. Feder & Luis A. Ruedas
Host shifts of phytophagous insect specialists to novel plants can result in divergent ecological adaptation, generating reproductive isolation and potentially new species. Rhagoletis pomonella fruit flies in eastern North America underwent a host shift ~160 ya from native downy hawthorn (Crataegus mollis) to introduced, domesticated apple (Malus domestica). Divergent selection on diapause phenology related to the earlier fruiting time of apples versus downy hawthorns resulted in partial allochronic reproductive isolation between the fly races. Here,...

Data from: Social status, immune response, and parasitism in males: a meta-analysis

Bobby Habig & Elizabeth A. Archie
In male vertebrates, two conflicting paradigms—the energetic costs of high dominance rank and the chronic stress of low rank—have been proposed to explain patterns of immune function and parasitism. To date, neither paradigm has provided a complete explanation for status-related differences in male health. Here, we applied meta-analyses to test for correlations between male social status, immune responses, and parasitism. We used an ecomimmunological framework, which proposes that males should re-allocate investment in different immune...
