Breeding Biology, Behavior, and Morphology of Emperor Geese and Other Waterfowl near Kokechik Bay, Yukon Delta National Wildlife Refuge, Alaska during 1982-1988

This data package presents legacy data on Emperor Goose, Cackling Goose, Black Brant, and Greater White-fronted Goose, breeding biology, behavior, and morphology collected at study sites near Kokechik Bay on the Yukon Delta National Wildlife Refuge (previously Clarence Rhodes National Wildlife Refuge), Alaska during the summers of 1982 through 1988. These data were collected to provide a basis for the evaluation of long-term changes in Emperor Goose and other waterfowl biology on the Yukon-Kuskokwim Delta, Alaska.

Waterfowl Lead Exposure Data in Alaska and Russia

This dataset identifies lead (Pb) concentration found in the blood of waterfowl sampled in western and northern Alaska and eastern Russia between 1993 and 2022. Data include age, sex, body measurement, capture location, presence or absence of lead shot on x-rays, and blood lead levels. Because the study took place over a number of years at the same study sites, many of the same birds were sampled in multiple years.

Results from local knowledge of berry resources surveys administered to community experts in four villages of the Yukon-Kuskokwim Delta, Alaska

A trichotomous choice survey was used to document local expert observations of five berry species locally known as: salmonberry (Rubus chamaemorus), blackberry (Empetrum nigrum), cranberry (Vaccinium vitis-idaea), blueberry (Vaccinium uliginosum), and red berry (Rubus arcticus). The survey consisted of propositions concerning importance of specific berry species within Indigenous households; observations of changes in berry abundance, phenology, habitat, or availability; attribution of potential drivers of change; and instance of changes in behavior in response to changing berry resources. Respondents were asked to agree (yes) or disagree (no) with propositions or state that they were unsure of an answer (don’t...
