Expanding a Dynamic Model of Species Vulnerability to Climate Change for Hawai‘i and Other Pacific Island Ecosystems
Initial studies suggest terrestrial Hawaiian plant species may be vulnerable to climate change. However, these models lack information on species-specific traits that affect ecological and evolutionary responses of species to climate change. Research is needed to refine current vulnerability models and apply these to Pacific Islands outside Hawai‘i.
Interagency Grizzly Bear Study Team
The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 as a direct result of controversy surrounding the closure of open pit garbage dumps within Yellowstone...
Wildlife Responses to Climate, Land Use, and Invasive Species
Wildlife issues drive many federal and state land management decisions, either because of litigation or mandates to protect habitat and limit extinction risks. We conduct applied research to meet this need, particularly related to the effects of natural (disease, predation) and anthropogenic (habitat loss, invasive species) stressors on wildlife populations and communities. Research on the effects...
Effects of Climate Change and Other Environmental Stressors on Water Birds and Their Habitats
Predicted climate impacts on arid U.S. Great Basin wetlands will alter their number, distribution, and quality (e.g., salinity). The scarcity and isolation of these wetlands make them essential not only to wildlife but to ranchers, farmers, and urban areas that rely on their ecosystem services. Great Basin wetlands are important habitats for migratory birds at high volumes, but they become...
Coastal Ecosystem Response to Sea-level Rise
USGS WERC’s Dr. Karen Thorne, her team of reseachers, and her partners are currently taking a local site network approach to describe current and future conditions and projected responses of coastal ecosystems to sea-level rise and other stressors. The Coastal Ecosystem Response to Climate Change (CERCC) program’s goal is to understand how ecosystems vary in their ability to keep up with sea-level...
Ecology and Population Dynamics of Ridgway's Rails along the West Coast of the U.S.
The Ridgway’s rail is a federal and state listed endangered species that occurs in wetlands along the Pacific Coast and from the Lower Colorado River drainage to southern Baja California. Three subspecies of Ridgway’s rail are found within the United States: the California Ridgway’s Rail, Yuma Ridgway’s rail, and Light-footed Ridgway’s rail. All three subspecies have declined since 1900 as a...
Environmental Stressors and Wildlife Health
Environmental stressors such as contaminants and disease can cause physiological imbalance in all types of wildlife. WERC’s Drs. Lizabeth Bowen and A. Keith Miles develop gene transcription profiles to detect organisms’ physiological responses to environmental stressors and provide resource managers with early warnings for potential effects on wildlife and ecosystem health.
Habitat Dynamics
The Habitat Dynamics Project examines how short and long-term changes in the environment affect the distribution and survival of wildlife populations.
Sea-Level Rise and Tsunami Vulnerability of Habitat and Wildlife of the Northwestern Hawaiian Islands
Low-elevation Pacific islands are vulnerable to inundation from sea-level rise and sudden flooding events. The largely low-lying islands of Northwestern Hawaiian Islands (NWHI), that extend 1,930 km beyond the main Hawaiian Islands, are a World Heritage Site and part of the Papahānaumokuākea Marine National Monument. The NWHI support the largest tropical seabird rookery in the world, provide...
Managing the Extinction Risk of the Shenandoah Salamander
The Shenandoah salamander is an endangered salamander that is at risk of extinction due to its small, high-elevation range, competition with the co-occurring red-backed salamander, and the predicted future climate in the Appalachian mountain range. We are working with multiple partners to understand the current status of the species, predict future extinction risk, and continually engage...
Improving Our Ability to Forecast Tidal Marsh Response to Sea Level Rise
Our overall objective is to understand what controls the vulnerability of coastal marshes to risks associated with global change drivers and rising sea levels. Fundamental questions pertaining to coastal wetland vulnerability still need to be addressed. What factors explain spatial and geographic variation in tidal wetland vulnerability? How do short term climatic events (storms) influence the...
