Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Solar farms can mitigate negative impacts of whiplash weather on plant communities in a dryland ecosystem

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Utility‐scale solar energy (USSE) development generates novel questions regarding coupling clean energy production with terrestrial ecosystem services (e.g., forage production, pollinator support). We found that a USSE array sited in a fallowed cropland maintained a reseeded native plant community even a decade post‐restoration and that the array ...

The most threatened plants receive the least scientific attention

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.
