Aim In response to warming, species are shifting their ranges towards higher elevations.
These elevational range shifts have been documented in a variety of taxonomic groups across …

Fire regimes are a major agent of evolution in terrestrial animals. Changing fire regimes and
the capacity for rapid evolution in wild animal populations suggests the potential for rapid, …

Rapid species turnover in tropical mountains has fascinated biologists for centuries. A
popular explanation for this heightened beta diversity is that climatic stability at low latitudes …

Laboratory techniques for high‐throughput sequencing have enhanced our ability to
generate DNA sequence data from millions of natural history specimens collected prior to the …

Predictable trait variation across environments suggests shared adaptive responses via
repeated genetic evolution, phenotypic plasticity or both. Matching of trait–environment …

In the painted bunting (Passerina ciris), a North American songbird, populations on the Atlantic
coast and interior southern United States are known to be allopatric during the breeding …

The extent to which species ranges reflect intrinsic physiological tolerances is a major question
in evolutionary ecology. To date, consensus has been hindered by the limited tractability …

The Mariana islands have a species-poor but functionally diverse and largely endemic bird
assemblage that varies due to biogeographic legacy and anthropogenic impacts. The largest …

Janzen's seasonality hypothesis predicts that organisms inhabiting environments with
limited climatic variability will evolve a reduced thermal tolerance breadth compared with …
