Major axes of variation in tree demography across global forests

This study identifies key sources of variation in tree demography across global forests using a variance partitioning framework, finding species differences as a major driver of demographic variance.

Effects of disease emergence on invasive grass impacts

This study examines how an emerging fungal disease affects the invasive grass Microstegium vimineum and its native competitor Elymus virginicus, finding that disease does not reduce invader abundance but may suppress competitor abundance over time.

Diversification of ergot alkaloids and heritable fungal symbionts in morning glories

The paper shows that ergot alkaloids in morning glories are concentrated in specific clades and correlate with seed mass, suggesting defensive symbiosis benefits larger seeds.

Lizard feeding enhances Ixodes pacificus vector competency

This study shows that feeding Ixodes pacificus larvae on lizards increases their likelihood of becoming infected with Borrelia burgdorferi compared to feeding on mice, and alters gene regulation.

Novel genome characteristics contribute to the invasiveness of Phragmites australis (common reed)

This study identifies genomic features of invasive Phragmites australis that contribute to its invasiveness compared to native genotypes.

Invasive grass litter suppresses native species and promotes disease

This study shows invasive grass litter suppresses native plants and promotes disease in a greenhouse experiment with Microstegium vimineum and Elymus virginicus.
