Overview Fishes of the Adirondack Park face numerous challenges. Summer Suckers are the only endemic vertebrate yet have suffered major range reductions, so we are analyzing their genome, body shape, and spawning timing to verify their uniqueness and current range. Warming patterns are expected to shift their spawning earlier, potentially intersecting with their recent ancestor (White Suckers) to create hybridization and reduced reproductive success. Minnows are more diverse in the Adirondacks, and our analyses suggest that they show three major distributional patterns that reflect post-glacial colonization and temperature preferences. We are analyzing data from hundreds of lakes to discern the rules that structure...

The Pacific Islands Climate Adaptation Science Center (PI CASC) supports sustainability and climate adaptation in communities across the Pacific Islands by providing natural and cultural resource managers with access to actionable science specific to the region. PI CASC is hosted by the University of Hawaiʻi at Mānoa (UHM) with consortium partners at the University of Hawaiʻi at Hilo (UHH) and the University of Guam (UOG). During the period of 2019 - 2024, the PI CASC consortium will strive to i) build resiliency and sustainability in ecosystems and communities to climate change impacts; ii) strive to develop the best actionable climate science, while maintaining a non-advocacy stance; and iii) apply the elements...

Fire has always been a part of life in southern California. Climate change and current fire management practices have led to catastrophic losses and impacts to human health, infrastructure and ecosystems, as seen, for example, in the 2018 Montecito debris flow. Indigenous wisdom instructs that rather than suppressing fire, we should seek to be in good relationship with fire. This project centers the voices of Chumash people by revitalizing their good relationship with fire in Chumash homelands. This revitalization comes at a critical time for both fire management and revitalization of Indigenous cultural burning practices in the southwest. The project will enable the recovery and documenting of Chumash knowledge...

This project is an annual communicating memo explicitly designed to inform the Alaska Migratory Bird Comanagement Council and related partners of the survey results and subsequent population index for emperor geese (Anser canagicus) for incorporation of the data into the harvest management strategy and regulatory processes. This memorandum is additionally shared widely with partners outside the USFWS. The major products are an annual report in .pdf format and the associated R Markdown generating code.

Combined population indices of ducks and loons (YKD) and geese and swans (YKG) for the USFWS Region Migratory Bird Management Alaska Yukon-Kuskokwim Delta Aerial Survey study area in a combined csv format. The survey consists of low-level aerial observations of waterfowl on a stratified strip transect design. The resulting data frame is several indices combined over observers (or single observer in years where estimates were not combined) and calculated using a standard ratio estimator. These data are output from the R package AKaerial and are also available within that package, see https://github.com/USFWS/AKaerial.

Dusky Canada geese (Branta canadensis occidentalis) comprise one of the smallest populations of geese in North America and their breeding range is limited to Prince William Sound, primarily the Copper River Delta, and Middleton Island, Alaska. The Alaska Region of Migratory Bird Management initiated an aerial breeding pair survey on the Copper River Delta in 1986 after reported declines in the abundance of dusky Canada geese on their nesting and wintering grounds. Since 2008, the Pacific Flyway Council uses results of the aerial breeding pair survey, together with Middleton Island ground counts conducted by the Alaska Department of Fish and Game, as a management index to determine optimal hunting regulations. Survey...
