Erik Beever, Ph.D.
Erik 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.
Research Interest
Dr. Erik Beever has published over 100 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 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.

Predictors of current and longer-term patterns of abundance of American pikas (Ochotona princeps) across a leading-edge protected area Predictors of current and longer-term patterns of abundance of American pikas (Ochotona princeps) across a leading-edge protected area
American pikas (Ochotona princeps) have been heralded as indicators of montane-mammal response to contemporary climate change. Pikas no longer occupy the driest and lowest-elevation sites in numerous parts of their geographic range. Conversely, pikas have exhibited higher rates of occupancy and persistence in Rocky Mountain and Sierra Nevada montane ‘mainlands’. Research and monitoring...

Microrefuges and the occurrence of thermal specialists: implications for wildlife persistence amidst changing temperatures Microrefuges and the occurrence of thermal specialists: implications for wildlife persistence amidst changing temperatures
Background Contemporary climate change is affecting nearly all biomes, causing shifts in animal distributions, phenology, and persistence. Favorable microclimates may buffer organisms against rapid changes in climate, thereby allowing time for populations to adapt. The degree to which microclimates facilitate the local persistence of climate-sensitive species, however, is largely an open...
