The effects of body mass on immune cell concentrations of terrestrial mammals

Cynthia J. Downs, Ned A. Dochtermann, Ray Ball, Kirk C. Klasing & Lynn B. Martin
Theory predicts that body mass should affect the way organisms evolve and use immune defenses. We investigated the relationship between body mass and blood neutrophil and lymphocyte concentrations among 250+ terrestrial mammalian species. We tested whether existing theories (e.g., Protecton Theory, immune system complexity, and rate of metabolism) accurately predicted the scaling of immune cell concentrations. We also evaluated the predictive power of body mass for these leukocyte concentrations compared to sociality, diet, life history,...

Data from: Agriculturally dominated landscapes reduce bee phylogenetic diversity and pollination services

Heather Grab, Michael G. Branstetter, Nolan Amon, Katherine R. Urban-Mead, Mia G. Park, Jason Gibbs, Eleanor J. Blitzer, Katja Poveda, Greg Loeb & Bryan N. Danforth
Land-use change threatens global biodiversity and may reshape the tree of life by favoring some lineages over others. Whether phylogenetic diversity loss compromises ecosystem service delivery remains unknown. We address this knowledge gap using extensive genomic, community, and crop datasets to examine relationships among land use, pollinator phylogenetic structure, and crop production. Pollinator communities in highly agricultural landscapes contain 230 million fewer years of evolutionary history; this loss was strongly associated with reduced crop yield...

Data from: The heritability of behavior: a meta-analysis

Ned A. Dochtermann, Tori Schwab, Monica Anderson Berdal, Jermey Dalos & Raphael Royaute
The contribution of genetic variation to phenotypes is a central factor in whether and how populations respond to selection. The most common approach to estimating this influences is via the calculation of heritabilities, which summarize the contribution of genetic variation to phenotypic variation. Heritabilities also indicate the relative affect of genetic variation on phenotypes versus that of environmental sources of variation. For labile traits like behavioral responses, life-history traits, and physiological responses, estimation of heritabilities...
