Research Interest
Dr. Erik Beever has published over 75 articles in diverse scientific journals and in numerous subdisciplines of biology. He has performed field research on plants, soils, amphibians, birds, reptiles, fishes, and insects, as well as small, medium, and large mammals. His work has spanned salt-scrub, sagebrush-steppe, alpine, subalpine, subarctic, riparian, primary and secondary temperate and tropical forest, and coastal ecosystems of the western hemisphere. In addition to seeking to understand mechanisms of biotic responses to long-term weather patterns and variability, he has also focused on disturbance ecology and monitoring in conservation reserves, all at community to landscape scales, as well as other topics of conservation ecology, wildlife biology, and landscape ecology. He is interested in questions at the nexus of basic and applied science, especially those that also inform management and conservation efforts for species, communities, and ecosystems. He is a member of the IUCN Protected Areas Specialist Group, the IUCN Lagomorph Specialist Group, as well as The Wildlife Society, Society for Conservation Biology, American Society of Mammalogists, and Sigma Xi.

Status: Active Adaptive Capacity: The Linchpin for Understanding and Addressing Species Vulnerability to Climate Change Impacts
Different species have different ways of coping with changing climate conditions. Some species may move to more-favorable habitats, others may change their behavior (such as by shifting their diets), and still others may change the timing of life-cycle events (such as migration). The ability of a species to accommodate changing conditions is known as its “adaptive capacity”. Understanding the...

Status: Active Adaptive Capacity: the linchpin for understanding and addressing species vulnerability to climate-change impacts
When prioritizing natural resource management activities, managers need to understand how plant and animal species differ in terms of their vulnerability to variation in environmental conditions caused by climate change. Species vulnerability to climate change is controlled by (1) exposure to changing environmental conditions, (2) sensitivity to direct and indirect effects of those changing...

Design, Analysis, Monitoring, and Conservation of Ecological Dynamics at Broad Scales
There is increasing recognition that the spatial context in which any ecological process or phenomenon occurs has great bearing on the outcome of that process. Since 1994, we have been working on numerous field investigations and conceptual developments to inform how ecological resources can be managed and conserved across jurisdictional boundaries and broad spatial extents. Because such...

Grazing, Ungulate, and Disturbance Ecology
We work with a diverse collection of other researchers and resource managers, at local to national and international levels, to address ways in which herbivory and grazing systems interact with the broader ecosystems in which they occur. We investigate whether long-term weather patterns may interact synergistically to affect how soils, vegetation, and other animals respond to grazing or...

We work with a diverse collection of researchers, resource managers, and conservation practitioners to address the “how” and “why” questions that underlie species-and ecosystem-level responses to long-term weather patterns. Although it is more challenging, this level of more-mechanistic understanding is critical for informing climate-adaptation actions and strategies. We use a diversity of...

Freezing in a warming climate: Marked declines of a subnivean hibernator after a snow drought
Recent snow droughts associated with unusually warm winters are predicted to increase in frequency and affect species dependent upon snowpack for winter survival. Changes in populations of some cold‐adapted species have been attributed to heat stress or indirect effects on habitat from unusually warm summers, but little is known about the...

Persist in place or shift in space? Evaluating the adaptive capacity of species to climate change
Assessing the vulnerability of species to climate change serves as the basis for climate‐adaptation planning and climate‐smart conservation, and typically involves an evaluation of exposure, sensitivity, and adaptive capacity (AC). AC is a species’ ability to cope with or adjust to changing climatic conditions, and is the least understood and most...
