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.

A multi‐source remote sensing approach to identify and predict delayed succession in human‐dominated tropical landscapes

Journal of Applied Ecology, EarlyView.
Our study challenges the view that fire prevention alone is sufficient for restoring degraded landscapes. We show successful natural regeneration hinges on nearby remnant woodlands acting as crucial seed sources. This research provides a remote sensing framework to quantify the risk of delayed succession where ecosystems fail to recover within a short ...

Soil inoculation improves tree seedling growth in substrates containing bitumen, but the effect varies by species and inoculum source

Journal of Applied Ecology, EarlyView.
Soil inoculation improved tree seedling growth in some substrates containing bitumen, but the effect varied by species and inoculum source. Inoculum from extreme environments, such as the abandoned ore pile, may harbour microbes effective in supporting pine seedling growth in soils with residual hydrocarbons.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, EarlyView.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still
