Observations of Migrating Golden Eagles ( Aquila chrysaetos) in Eastern Interior Alaska Offer Insights On Population Size and Migration Monitoring
Migratory Golden Eagles ( Aquila chrysaetos) from Alaska winter across a vast region of western North America, much of which is undergoing rapid change from a diversity of indirect and direct human activities. To address recent conservation concerns, we are studying the year-round movements of migratory Golden Eagles from interior and northern Alaska to identify and evaluate potential risks to their survival. We are also developing new survey techniques to estimate population size and trends. As part of our ongoing studies, we observed migrating Golden Eagles in spring and autumn 2014 during field investigations to locate Golden Eagle capture sites in eastern interior Alaska, and in spring 2015 during capture activities....

Remote Sensing of 2000–2016 Alpine Spring Snowline Elevation in Dall Sheep Mountain Ranges of Alaska and Western Canada
Life history variability includes phenotypic variation in morphology, age, and size at key stage transitions and arises from genotypic, environmental, and genotype-by-environment effects. Life history variation contributes to population abundance, productivity, and resilience, and management units often reflect life history classes. Recent evidence suggests that past Chinook salmon (Oncorhynchus tshawytscha) classifications (e.g., ‘stream’ and ‘ocean’ types) are not distinct evolutionary lineages, do not capture the phenotypic variation present within or among populations, and are poorly aligned with underlying ecological and developmental processes. Here we review recently reported variation in juvenile Chinook...
What Came First, the Nest or the Egg? An Unusual Golden Eagle Nest Observed in Denali National Park and Preserve, Alaska
The article presents the result of monitoring conducted on nests built by Golden eagle, Aquila chrysaetos, at Denali National Park and Preserve in Alaska. The observation includes territory occupancy and breeding activities of the eagle, rate of nesting success and production. The types of tree and plant branches used, the estimated age of the nests and the relations of egg with the nest are also monitored.
