Species that respond to ecosystem change in a timely, measurable, and interpretable way
can be used as sentinels of global change. Contrary to a pervasive view, we suggest that …

Bobcats Lynx rufus and coyotes Canis latrans are two widespread mesopredators with a
complex history of sympatry. The competitive interactions between these species are of …

Assessing the spatiotemporal overlap amongst animal species living in sympatry helps to
shed light on mechanisms of interspecific coexistence. We analysed the spatiotemporal …

Mesocarnivores fill a vital role in ecosystems through effects on community health and
structure. Anthropogenic-altered landscapes can benefit some species and adversely affect …

The competitive exclusion principle states that ecologically similar species will be unable to
coexist due to competition for resources, however, similar species coexist across a variety of …

Background Spatial behavior, including home-ranging behaviors, habitat selection, and
movement, can be extremely informative in estimating how animals respond to landscape …

A bstract Perturbations in ecological processes can occur when wildlife alter their
spatiotemporal activity patterns to avoid human activities that they perceive as a risk. Such …

Individuals that inhabit broad elevational ranges may experience unique environmental
challenges. Because temperature decreases with increased elevation, the ectotherms living …

Anthropogenic activities can profoundly affect ecological communities. This is true of the
most ubiquitous type of anthropogenic land-use, livestock grazing. While livestock grazing is …

The jaguarundi (Puma yagouaroundi) is a small felid with a historical range from central
Argentina through southern Texas. Information on the current distribution of this reclusive …
