Terrestrial Mammals

Research in this focal area is centered on (i) collecting data on a variety of systems that help determine and mediate polar bear health and energetics, and (ii) developing monitoring and surveillance programs for detecting changes in population health over time. Additionally, this work will allow us to develop an understanding of how polar bear populations will respond to a variety of stressors...

Most national parks interact with adjacent lands because their boundaries fail to encompass all regional habitats, species pools, and migration routes. Activities planned for adjacent lands can have adverse effects on park resources and visitor experiences. For example, fragmentation of adjacent habitat into smaller and more isolated remnants may influence the suitability of park habitat for a...

Maintaining a current understanding of ecological conditions is fundamental to the National Park Service in meeting its mission to preserve park resources in an unimpaired state for future generations. Ecological monitoring establishes reference conditions, which over time help to define the normal limits of natural variation, determine standards for comparing future changes, and identify the need...

Citizen scientists can now help dig into San Diego's urban wildlife mysteries. Join WERC ecologists as they track wild badgers and explore the connectivity of Southern California's natural landscapes.

National parks and other protected areas are key components of the wildlife conservation landscape. The goal of wildlife managers in national parks is to preserve the ecological integrity and authenticity of natural systems for future generations. Wildlife populations of national parks, however, are in continuous flux as a result of changing land uses outside their boundaries, climate variability...

This research theme informs adaptive management and siting decsions in relation to bats at wind and solar power-generation facilities.

Special status species and habitats are often sentinels of accelerated ecosystem change and, by definition, are priorities for protection, restoration, or focused management.

WERC's Dr. Amy Vandergast and colleagues merge genetic data with mapping and modeling tools to inform biodiversity conservation efforts. They define evolutionary significant units within species, reveal evolutionary mechanisms responsible for diversification, and identify regions with high genetic diversity for protection.

The primary goal of this bat research program is to develop projects that increase our understanding of basic ecology and natural history of western bat species, while simultaneously providing needed data to inform conservation measures and management decisions in the West. Dr. Brian Halstead, together with Gabriel Reyes, studies the habitat and resource selection, movement ecology, demography...

Dr. Kathleen Longshore’s goal is to understand how predator/prey relationships, disease and human-caused disturbance work separately and synergistically to impact bighorn sheep populations under variable ecological stress. Information from this project will provide managers with an understanding of specific and regional impacting factors that contribute to impact variation in population trends.

The terrestrial biota of the Central Pacific is primarily defined by its degree of isolation. At the center lies the Hawaiian Archipelago, which is more than 3,200 km from any continental land mass. After tens of millions of years of evolutionary isolation from all mammals except bats, islands of the Central Pacific were quite suddenly besieged by a number of alien rodents, carnivores and both...

The Habitat Dynamics Project examines how short and long-term changes in the environment affect the distribution and survival of wildlife populations.
