Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Ecological Entomology, EarlyView.Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Range expansion of an already widespread bee under climate change
Global Ecology and Conservation, 2019 Climate change is a key threat to pollination networks and has already caused shifts in the distribution and phenology of many bee species. Predictions based on species distribution models forecast that most bee species will continue to decline as ...

Relationships Between Shared Group Properties: Theory, Measurement, Estimation, and Adjustment
Personnel Psychology, EarlyView.ABSTRACT Teams researchers, meta‐analysts, and others often study relationships between group‐level constructs measured by aggregating individual‐level variables, but it is well‐known that group‐mean correlations are influenced by individual‐level relationships.
