Swan Research
USGS research on swans in Alaska has focused on pathogens, contaminants, and demographic rates in each of the different breeding areas of Alaska. The vastly different migration patterns of swans in Alaska means that there are multiple factors on the wintering grounds and during migration that may influence population size and trends.Spatial and Temporal Maps of Population Change of Waterbirds on Alaska's North Slope
A main objective of the USGS Changing Arctic Research Initiative is to quantify and provide projections of the responses of wildlife species and their habitats to ecosystem change in the Arctic. The following project provides information for Department of Interior agencies, industry, and other stakeholders related to this objective.Changing Arctic Ecosystems
Arctic regions of Alaska are important for cultural and economic sustainability and host a wide variety of wildlife species, many of which are of conservation and management interest to the U.S. Department of the Interior. The USGS and collaborators provide information about Arctic ecosystems that are used by Arctic residents, management agencies, and industry.Goose Research
The USGS Alaska Science Center has had a focus on addressing science questions related to geese in Alaska for decades. Information on these species is critical because all are important resources for subsistence and sport hunters in the state and outside of Alaska where these birds spend the winter. The large majority of goose populations in Alaska breed on national wildlife refuges (managed by...Sea Duck Research
USGS research on sea ducks is designed to anticipate and address priority information needs of management agencies. Additionally, work is focused on individual species biology, migration and population status and trends because until just recently, very little was known about sea ducks in Alaska.Dabbling and Diving Duck Research
Dabbling and diving ducks, such as mallards, pintails and scaup, are widespread species throughout North America. Additionally, their migratory flyways pass through Asia and North America overlap in Alaska. Population trends of these species are closely tracked through aerial surveys by management agencies. Results from these and other surveys are then used to formulate management actions to...Wildlife Disease and Environmental Health in Alaska
Environmental health is defined by connections between the physical environment, ecological health, and human health. Current research within the U.S. Geological Survey (USGS) recognizes the importance of this integrated research philosophy, which includes study of disease and pollutants as they pertain to both wildlife and humans. Due to its key geographic location and significant wildlife... - Data

Filter Total Items: 126Effects of mass capture on survival of greater white-fronted geese in Alaska
Mass capture of flightless geese during the summer is a common trapping technique to obtain large numbers of individuals for research and marking, but few studies have assessed the impacts of this method on the survival of after-hatch-year geese. We evaluated the effects of holding time and captured flock size on the survival of >26,000 subadult (second yr) and adult (≥third yr) greater white-fronGrowth of greater white-fronted goose goslings relates to population dynamics at multiple scales
The abundance of greater white-fronted geese (Anser albifrons frontalis) on the Arctic Coastal Plain (ACP) of northern Alaska, USA, has more than tripled since the late 1990s; however, recent rate of annual population growth has declined as population size increased, which may indicate white-fronted geese on the ACP are approaching carrying capacity. We examined rates of gosling growth in greaterNegligible evidence for detrimental effects of Leucocytozoon infections among Emperor Geese (Anser canagicus) breeding on the Yukon-Kuskokwim Delta, Alaska
Emperor Geese (Anser canagicus) are iconic waterfowl endemic to Alaska and adjacent areas of northeastern Russia that are considered to be near threatened by the International Union for Conservation. This species has been identified as harboring diverse viruses and parasites which have, at times, been associated with disease in other avian taxa. To better assess if disease represents a vulnerabiliTemporal variation in genetic structure within the threatened spectacled eider
We examined the genetic structure of the threatened spectacled eider 14–18 years after the initial assessment to evaluate the influence of population recovery on diversity. Concordant with the initial assessment, spectacled eiders were highly structured at mitochondrial (mt) DNA and lacked differentiation at microsatellite loci. The degree and spatial pattern of structure has changed at mtDNA; aThe black brant population is declining based on mark recapture
Annual survival and recruitment in black brant (Branta bernicla nigricans) have declined since the 1990s, yet aerial surveys of the global population have been stable or even increasing over the past decade. We used a combination of a Lincoln estimator based on harvest information and band recoveries, and marked‐unmarked ratios in bag checks in 1 harvest area in Mexico to estimate the number of adSpatial distribution of band recoveries of black brant
On average, band recovery rates of adult black brant (Branta bernicla nigricans) more than doubled between the 2000s and 2010s. However, the spatial distribution of band recoveries of black brant has not been reported. Our objective was to describe the spatial distribution of band recoveries of black brant since 1990. We found that Alaska, California, and Mexico accounted for ≥89% of band recoveriNon‐linear effect of sea ice: Spectacled Eider survival declines at both extremes of the ice spectrum
Understanding the relationship between environmental factors and vital rates is an important step in predicting a species’ response to environmental change. Species associated with sea ice are of particular concern because sea ice is projected to decrease rapidly in polar environments with continued levels of greenhouse gas emissions. The relationship between sea ice and the vital rates of the SpeSpring temperature, migration chronology, and nutrient allocation to eggs in three species of arctic‐nesting geese: Implications for resilience to climate warming
The macronutrients that Arctic herbivores invest in their offspring are derived from endogenous reserves of fat and protein (capital) that females build prior to the period of investment or from foods they consume concurrently with investment (income). The relative contribution from each source can be influenced by temporal and environmental constraints on a female's ability to forage on Arctic brPhenological mismatch in coastal western Alaska may increase summer season greenhouse gas uptake
High latitude ecosystems are prone to phenological mismatches due to climate change- driven advances in the growing season and changing arrival times of migratory herbivores. These changes have the potential to alter biogeochemical cycling and contribute to feedbacks on climate change by altering greenhouse gas (GHG) emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) throughLong‐term trends in fall age ratios of black brant
Accurate estimates of the age composition of populations can inform past reproductive success and future population trajectories. We examined fall age ratios (juveniles:total birds) of black brant (Branta bernicla nigricans; brant) staging at Izembek National Wildlife Refuge near the tip of the Alaska Peninsula, southwest Alaska, USA, 1963 to 2015. We also investigated variation in fall age ratiosGenetic structure among greater white-fronted goose populations of the Pacific Flyway
An understanding of the genetic structure of populations in the wild is essential for long-term conservation and stewardship in the face of environmental change. Knowledge of the present-day distribution of genetic lineages (phylogeography) of a species is especially important for organisms that are exploited or utilize habitats that may be jeopardized by human intervention, including climate chanBiochemical and clinical responses of Common Eiders to implanted satellite transmitters
Implanted biologging devices, such as satellite-linked platform transmitter terminals (PTTs), have been used widely to delineate populations and identify movement patterns of sea ducks.
