Wildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.
