Abiotic variables drive different aspects of fish community trait variation and species richness across the continental United States

Journal of Animal Ecology, EarlyView.
Trait distributions provide insight into how niches overlap within a broader trait space. By integrating individual‐level trait observations from different communities, we can explore how facets of trait dimensionality vary across environmental conditions.

Data reconciliation in multi‐trait experiments with kinship ordination

Methods in Ecology and Evolution, EarlyView.
Abstract A central aim in biology is understanding the heritability of traits and how trait interactions contribute to success in diverse environments. Experiments that record multiple traits from individuals of known pedigree or genetic relatedness in distinct environments are key to addressing this aim.
