    “…We evaluated these three hypotheses using mark-recapture data from an 8-year study of hoary marmot (Marmota caligata) population dynamics in the Yukon. Annual variation in breeding probability was modeled using multi-state mark-recapture models, while other reproductive life-history traits were modeled with generalized linear mixed models. …”

    “…We found that deciduous trees removed 17.8–20.9 billion m(3) of snowmelt water, which is equivalent to 8.7–10.2% of the Yukon River’s annual discharge. Deciduous trees transpired 2–12% (0.4–2.2 billion m(3)) of the absorbed snowmelt water immediately after leaf-out, increasing favorable conditions for atmospheric convection, and an additional 10–30% (2.0–5.2 billion m(3)) between leaf-out and mid-summer. …”

    “…The most northern population (Arctic Coastal Plain) migrated westward to East Asia and traveled approximately 2,000 km farther to wintering sites than the three more southerly populations (Seward Peninsula, Yukon-Kuskokwim Delta, and Copper River Delta) which migrated south along the Pacific coast of North America. …”

    “…This paper documents a mass en route mortality event of adult summer chum salmon (Oncorhynchus keta) returning to the Koyukuk River, Alaska in the Yukon River basin. In response to reports from local communities, a small team of researchers (including the author) surveyed ca. 275 km of river on July 26 and 27, 2019 and counted 1,364 dead salmon. …”

    “…Because a major element of the threat from climate change stems from its novel geographic patterns, we examined, as an example, the implications for climate‐adaptation planning of latitudinal, longitudinal (continental to maritime), and elevational gradients in climate‐change exposure across the Yellowstone‐to‐Yukon region, the locus of an iconic conservation proposal initially designed to conserve wide‐ranging carnivore species. …”
