Functional and phylogenetic convergence of winter and breeding bird communities in the northeastern US

open access: yesEcography, EarlyView.
Around the world, ecological communities are becoming more similar to one another in a process known as biotic homogenization – an increase in similarity among communities over time. While biotic homogenization has been widely studied among spatial communities, very little attention has been paid to beta diversity between seasonal communities ...

Evolutionary trajectories of multiple defense traits across phylogenetic and geographic scales in Vitis

open access: yesEcography, EarlyView.
The processes driving defense trait correlations may vary within and between species based on ecological or environmental contexts. However, most studies of plant defense theory fail to address this potential for shifts in trait correlations across scales.

Assessing benthos through predator stomach contents: spatiotemporal modeling of abundance and habitat use

open access: yesEcography, EarlyView.
In shelf ecosystems, benthic invertebrates facilitate nutrient recycling and the transfer of energy to higher trophic levels. However, large‐scale monitoring through direct sampling (e.g. using benthic grabs or bottom trawls) can be costly in terms of time and labor.
