As the origin of three major basins that drain the Columbia, Missouri, and Saskatchewan rivers, Montana is the hydrologic apex for North America. The Northern Rocky Mountain region is home to some of the last remaining interconnected habitats for many native fishes, including the threatened bull trout and native westslope cutthroat trout. The Northern Rockies are also experiencing...

Fire size, frequency, overall area burned, and severity are increasing across many vegetation types in the southwestern U.S. In many cases, large contiguous areas are burning repeatedly at high severity, triggering vegetation type conversions (VTC), where once-dominant coniferous forests fail to return to their pre-fire state, often transitioning to shrub- or grass-dominated systems...

Climate change represents one of the foremost drivers of ecological change, yet its documented impacts on biodiversity remain uncertain and complex. Although there have been many published studies on species shifting their geographic ranges in response to climate change, it is still challenging to identify the specific mechanisms and conditions that facilitate range shifts in some...

Different species have different ways of coping with changing climate conditions. Some species may move to more-favorable habitats, others may change their behavior (such as by shifting their diets), and still others may change the timing of life-cycle events (such as migration). The ability of a species to accommodate changing conditions is known as its “adaptive capacity”...

The Mediterranean ecosystems of southern California are some of the most ecologically diverse systems in the world. The diversity of plants and animals, as well as high rates of endemism, make the area a biodiversity hotspot. High diversity in plant and animal species contributes greatly to the health and productivity of ecosystems, and plays an important role in the local and state...

Hydrologic drought and declining water availability are among the foremost stressors of stream ecosystems in the Red River basin. Resource managers face the challenge of apportioning scarce water resources among competing uses, but they lack a systematic framework for comparing the costs and benefits of proposed water management decisions and conservation actions. In 2016, Co-PIs Neeson...

Invasive species have increasingly severe consequences for ecosystems and human communities alike. The ecological impacts of invasive species are often irreversible, and include the loss of native species and the spread of disease. Implications for human communities include damaged water transportation systems, reduced crop yields, reduced forage quality for livestock, and widespread...

Estuaries are located at the interface where rivers meet the sea, creating unique ecosystems with complex physical and biological processes. Coastal wetlands provide essential ecosystem services to people, including flood protection from high tides and storm surges, commercial fisheries, carbon sequestration, improved water quality, and wildlife food and habitat. Coastal wetlands are...

Fruit-producing shrubs such as huckleberries, salal, and hazelnut are an important component of social history and traditional tribal diets in the Pacific Northwest. The fruits of these shrubs are also an important food source for foraging wildlife and pollinators, and serve as the basis for both non-tribal harvesting and small-scale commercial operations. Among land managers and tribes...

Migratory birds are responding to changes in climate in complex and sometimes unpredictable ways. The timing of breeding and migration typically coincide with the periods of peak food availability; however, these peaks are shifting as temperatures and precipitation patterns change, resulting in a mismatch in the timing of key events. The degree to which this mismatch is impacting...

The Climate Change Response Framework is an example of a collaborative, cross-boundary approach to create a set of tools, partnerships, and actions to support climate-informed conservation and land management. Historically, this effort has focused on the needs of forest managers and forestry professionals. In recent years, however, there has been increasing demand for science and tools...

During the severe drought of 2010-2015, several communities in southeast Oklahoma almost ran out of water. Some of these communities rely on streams and rivers as their sole source of water and when these sources almost ran dry, it left them searching for alternatives and wondering how to continue growing, economically, with this water uncertainty. The possibility of climate change has...
