An investigation of aquatic invasive species in pristine sites in the Greater Yellowstone Area

Aquatic invasive species (AIS) are aquatic organisms that move into ecosystems beyond their natural, historic range and cause severe and irreversible damage to the habitats they invade. Most AIS arrive as a direct result of human activity, such as boating and angling. The threat of AIS introduction is especially high in the Greater Yellowstone Area, as humans from all over the world come to...

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...

Dust deposited on snow cover in the San Juan Mountains, Colorado, 2011-2016: Compositional variability bearing on snow-melt effects

Light-absorbing particles in atmospheric dust deposited on snow cover (dust-on-snow, DOS) diminish albedo and accelerate the timing and rate of snow melt. Identification of these particles and their effects are relevant to snow-radiation modeling and thus water-resource management. Laboratory-measured reflectance of DOS samples from the San Juan...
