The onset of spring, represented by first leaf and first bloom, is a critical indicator of the health and growth of ecosystems. Studies have shown that the timing of first leaf and first bloom has shifted to earlier in the year across the U.S., impacting species that time their own life history events based on spring onset. False springs occur when temperatures briefly warm and “trick”...

Hawaiian forest birds play important roles in many ecological processes. For example, 61% of native flowering Hawaiian plant species are either bird pollinated or dispersed through ingestion by birds. However, native bird communities across Hawaiʻi continue to decline despite efforts to control predators and enhance habitat. These declines are, in part, due to the mosquito-borne avian...

The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that...

Freshwater mussels are an important component of freshwater ecosystems. They can filter a large amount of water, affecting both water clarity and water chemistry. Their shells provide physical habitat for other organisms, they re-direct necessary nutrients to the bottom of the water column, and their excreted material can enhance the growth of algae and macroinvertebrates. However...

Hundreds of millions of dollars of public funding are invested annually in projects that aim to deliver research that can improve people’s lives and safeguard the environment. To invest that money wisely, we need to know how to design projects so that they will successfully address the information needs of natural resource managers. By using a process of systematic evaluation to assess...

The NE CASC consortium convenes three workshops that explore high-priority adaptation research topics emerging from our stakeholder networks and current DOI priorities. Workshops provide a platform to foster a collaborative community of scientists and managers, invite sharing and discussion of partner needs, and cross-disciplinary development and application of NE CASC-supported research

Climate change is likely to impact erosion rates, the magnitude and frequency of extreme rainfall/mass wasting events, and the accumulation of sediment in coastal areas. However, long-term rates of erosion and sediment delivery to coastal systems are poorly constrained and there is limited understanding of the relative effects of climate change versus land-use change on these processes

Some areas of the U.S. Affiliated Pacific Islands (USAPI) are experiencing a decline in precipitation and streamflow and an increase in the number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. As ecosystems become altered by invasive species and as

The South Central CASC supports Communities of Practice who are dedicated to finding solutions to the challenges of a changing climate. The Communities of Practice comprise researchers and stakeholders who share a common interest and choose to invest their time in learning from others and developing new collaborations. As of March 2021, the South Central CASC is actively supporting six...

Scientific information about the risks of climate change to important natural and cultural resources is crucial for developing and implementing climate adaptation plans and management actions. Tools that incorporate both science and expert knowledge on adaptation actions can greatly benefit municipal, regional, and other decision makers, as they develop and implement their adaptation...

The impacts of climate change are widespread and accelerating. As natural resource managers are tasked with maintaining and protecting species and ecosystems, options for minimizing the impacts of climate change are needed. One option for climate adaptation focuses on resistance, which seeks to preserve, as much as possible, the historical structure, composition, and function of an...

Overview A changing regional climate in the northeastern US has significant implications for the fundamental bioenergetics of fish species, with implications for their population resilience and their ability to provide critical ecosystem services, with particularly important implications for tribal communities. For example, warming soil and water temperatures may increase the...
