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.

Species and Ecosystem Responses to Global Change

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 study...

Hoary Marmot Abundance in North Cascades National Park 2007-2008 and 2016-2017 Hoary Marmot Abundance in North Cascades National Park 2007-2008 and 2016-2017

USGS and NPS biologists used distance sampling to estimate abundance of hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2007-2008 and 2016-2017. Biologists resurveyed hoary marmots in 2016 and 2017 at 78 point-count stations across 19 sites surveyed by NPS in 2007-2008. Data include marmot detection distances and survey conditions used to estimate

Combining past and contemporary species occurrences with ordinal species distribution modeling to investigate responses to climate change Combining past and contemporary species occurrences with ordinal species distribution modeling to investigate responses to climate change

Many organisms leave evidence of their former occurrence, such as scat, abandoned burrows, middens, ancient eDNA or fossils, which indicate areas from which a species has since disappeared. However, combining this evidence with contemporary occurrences within a single modeling framework remains challenging. Traditional binary species-distribution modeling reduces occurrence to two...

Evaluating ecosystem protection and fragmentation of the world's major mountain regions Evaluating ecosystem protection and fragmentation of the world's major mountain regions

Conserving mountains is important for protecting biodiversity because they have high beta diversity and endemicity, facilitate species movement, and provide numerous ecosystem benefits for people. Mountains are often thought to have lower levels of human modification and contain more protected area than surrounding lowlands. To examine this, we compared biogeographic attributes of the...

Geographic and taxonomic variation in adaptive capacity among mountain-dwelling small mammals: implications for conservation status and actions Geographic and taxonomic variation in adaptive capacity among mountain-dwelling small mammals: implications for conservation status and actions

Contemporary climate change is modifying the distribution, morphology, phenology, physiology, evolution, and interspecific interactions of species. Effects of climate change are mediated not only through the magnitude of change experienced (exposure) and an animal's sensitivity to such changes, but also through the ability of the population or species to adjust to climatic variability...

Spatio-temporal variability in the strength, directionality, and relative importance of climate on occupancy and population densities in a philopatric mammal, the American pika (Ochotona princeps) Spatio-temporal variability in the strength, directionality, and relative importance of climate on occupancy and population densities in a philopatric mammal, the American pika (Ochotona princeps)

Species distribution models (SDMs) have been widely employed to evaluate species–environment relationships. However, when extrapolated over broad spatial scales or through time, these models decline in their predictive ability due to variation in how species respond to their environment. Many models assume species–environment relationships remain constant over space and time, hindering...
