The rapid loss of arctic sea ice is forcing a larger proportion of the Southern Beaufort Sea polar bear (Ursus maritimus) population to spend more time on land, increasing chances of negative interactions between people and bears. In the United States, the Marine Mammal Protection Act (MMPA) protects polar bears from incidental disturbance from human activities. For the remote and roadless areas of northern Alaska, USA, effective management of small aircraft activity is necessary to limit disturbance, but effects of overflights on polar bear behavior are largely unknown. During 2021 and 2022, we intentionally exposed polar bears (n = 115) to systematic aircraft activity (helicopter, fixed-wing) until we observed...

NC State University (NCSU) has largely met target objectives described in the Term Sheet (provided by NCASC) for the Phase 2 reporting period from August 1, 2017 - August 1, 2024. Over this period, NCSU has augmented the scope of work due to leveraged activity, new partnerships across the university, and new consortium members. We welcomed five new consortium members at the start of this phase. This includes four university partners – Auburn University, Duke University, University of Florida, and University of Tennessee – that have specific contractual activities associated with the new host agreement; University of South Carolina continued research and development on partner projects initiated in Phase I. This...

As climate change accelerates, understanding which species are most vulnerable and why they are vulnerable will be vital to inform conservation action. Climate change vulnerability assessments (CCVAs) are tools to assess species' responses to climate change, detect drivers of vulnerability, and inform conservation planning. CCVAs are commonly composed of three elements: exposure, sensitivity, and adaptive capacity. Incorporating all three elements can be challenging, and including only two of the three elements may be a more feasible approach in many systems. Although two-element CCVA approaches have become more common, their utility and procedures remain poorly documented. We conducted a literature review to explore...

The primary goal of the Nicholas Institute’s work under the SE CASC host award was to advance the integration of ecosystem services concepts into natural resource management practices that are relevant to SE CASC. Their activities addressed both state and federal needs, driven by two key workstreams: (1) regional ecosystem services mapping and the development of pilot ecosystem accounts for the southeastern U.S., and (2) opportunity mapping and benefits quantification for natural and working lands in North Carolina.

Climate change is altering the thermal habitats of freshwater fish species. We analyze modeled daily temperature profiles from 12,688 lakes in the US to track changes in thermal habitat of 60 lake fish species from different thermal guilds during 1980-2021. We quantify changes in each species’ preferred days, defined as the number of days per year when a lake contains the species’ preferred temperature. We find that cooler-water species are losing preferred days more rapidly than warmer-water species are gaining them. This asymmetric impact cannot be attributed to differences in geographic distribution among species; instead, it is linked to the seasonal dynamics of lake temperatures and increased thermal homogenization...

The purpose of our project was to identify needs and provide support for states in the North Central region and Idaho to integrate climate science and adaptation into their State Wildlife Action Plans (SWAPs). Our objectives were to: 1) engage with state wildlife agencies in the North Central region and Idaho to identify their needs for climate-informed planning support and 2) collaboratively develop products that will help them better integrate climate adaptation strategies into SWAPs.

The Native Nations Climate Adaptation Program (NNCAP) was founded in 2015 with the mission to build capacity to work collaboratively with Native American tribes and indigenous populations in the western United States and Mexico. NNCAP received funds from the DOI Southwest Climate Science Center to carry out a “Tribal Adaptation Initiative.” One of the objectives of this initiative was to conduct a preliminary assessment of tribal interest and capacity for adaptation across the Southwest. Twenty-six Native Nations participated in the NNCAP tribal climate change assessment and reported a wide array of involvement in climate change initiatives. This report highlights various strengths and capacity needs for climate...
