Strong evidence for two disjunct populations of Black Scoters Melanitta americana in North America Strong evidence for two disjunct populations of Black Scoters Melanitta americana in North America
Black Scoters Melanitta americana were marked with satellite transmitters on Atlantic and Pacific coasts of North America to examine continental-scale population delineation. Scoters marked on the different coasts did not overlap at any stage of the annual cycle, suggesting that birds in the two regions could be monitored and managed as separate populations: 1) an Atlantic population...

Ecosystem response persists after a prolonged marine heatwave Ecosystem response persists after a prolonged marine heatwave
Some of the longest and most comprehensive marine ecosystem monitoring programs were established in the Gulf of Alaska following the environmental disaster of the Exxon Valdez oil spill over 30 years ago. These monitoring programs have been successful in assessing recovery from oil spill impacts, and their continuation decades later has now provided an unparalleled assessment of...

High site fidelity does not equate to population genetic structure for common goldeneye and Barrow's goldeneye in North America High site fidelity does not equate to population genetic structure for common goldeneye and Barrow's goldeneye in North America
Delineation of population structure provides valuable information for conservation and management of species, as levels of demographic and genetic connectivity not only affect population dynamics but also have important implications for adaptability and resiliency of populations and species. Here, we measure population genetic structure and connectivity across the ranges of two sister...

Reliability of external characteristics to age Barrow’s goldeneye Reliability of external characteristics to age Barrow’s goldeneye
Accurate assignment of age class is critical for understanding most demographic processes. For waterfowl, most techniques for determining age class require birds in hand, reducing utility for quickly and efficiently sampling a large portion of the population. As an alternative, we sought to establish an observation‐based methodology, achievable in the field with standard optics, for...

A synthesis of ten years of chemical contaminant monitoring data in National Park Service - Southeast and southwest Alaska networks A synthesis of ten years of chemical contaminant monitoring data in National Park Service - Southeast and southwest Alaska networks
With the exception of PAHs and trace metals, which were detected at 100% of the sites, all of the other contaminants were detected at varying frequencies. PBBs, Mirex and Endosulfans were not detected in any of the samples and Chlorpyrifos was only detected in five samples across four sites. Chlordanes were present at 79% of the sites while Butyltins were only detected at 20% of the...

Annual winter site fidelity of Barrow's goldeneyes in the Pacific Annual winter site fidelity of Barrow's goldeneyes in the Pacific
Coastal regions on the Pacific north coast of North America provide important wintering habitat for many species of sea ducks. Although winter range and habitat preferences are well described for most species, fidelity to coastal wintering sites is generally undocumented. Fidelity is an important factor necessary for understanding interactions with coastal developments and activities and
