Impacts of climate change on habitat quality: plant phenology interactions with animal use and fitness

Weather and climate impact terrestrial wildlife habitat through their influences on plant productivity. Plant phenology – the timing of life-history events such as green-up, flowering and senescence – provides one indicator of the timing and magnitude of productivity. Changes and variability in plant phenology in space and time are indicators of habitat quality, which is a driver of fitness...

Identification of Fire Refugia in Rocky Mountain Ecosystems of the U.S. and Canada: Development and Application of the Refugium Concept for Biodiversity Conservation over Large Spatial and Temporal Scales

We described the climate space of fire regimes in northwestern North America (Whitman and others 2015), and we are refining an approach to identify fire refugia – areas that do not burn or burn with lower severity through multiple fire events. We continue our collaboration to test the function of refugia for biodiversity conservation under current and future climate and fire scenarios. We...

Yellowstone Volcano Observatory (YVO)

Monitors and studies the active geologic processes and hazards of the Yellowstone Plateau volcanic field and its caldera. Yellowstone National Park contains the largest and most diverse collection of natural thermal features in the world. YVO also monitors volcanic activity in Montana, Wyoming, Colorado, Utah, and New Mexico.

Amphibian Research and Monitoring Initiative: Rocky Mountain Region

Decline of amphibian populations worldwide has prompted an international effort to determine causes of decline in various locations and ecosytems. Some causes which have been suggested include habitat alteration, introduced species, disease, and environmental stressors such as ultraviolet radiation, agricultural chemicals in groundwater, and contaminants in atmospheric deposition. The ...

The U.S. Geological Survey (USGS) released a report today describing salinity levels in streams and ground water in parts of Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming. The report concludes that although salinity varies widely throughout the region, levels have generally decreased in many streams during the past two decades.
