The Arctic is one of the fastest‐warming marine regions in the world, which is changing the timing of seasonal sea‐ice dynamics. The annual summer breakup of sea‐ice coincides with resource pulses, which provide critical food sources for consumers to exploit. Marine organisms respond behaviourally to exploit these resources, with some migrating to presumably maximize feeding opportunities, whereas others remain resident, provi...

Stable isotopes are commonly used to characterize food web structure and resource use by aquatic organisms. White muscle is generally preferred for stable isotope analysis of fishes. However, obtaining white muscle tissue typically requires lethal take or invasive sampling techniques, which are undesirable for small-bodied species or those of conservation concern. We assessed the use of fish fin as a nonlethal alternative to m...

Although drones are a promising alternative to traditional wildlife monitoring methods, validation efforts are needed to quantify the accuracy of abundance and distribution estimates obtained from using drones. We used drones equipped with high‐resolution Red‐Green‐Blue (RGB) and thermal cameras, coupled with machine learning techniques, to assess the abundance and thermal physiology in northern elephant seals ( Mirounga angus...

Fire–vegetation feedbacks potentially maintain global savanna and forest distributions. Accordingly, vegetation in savanna and forest ecosystems should have differential responses to fire, but fire response data for herbaceous vegetation have yet to be synthesized across biomes. Here, we examined herbaceous vegetation responses to experimental fire at 30 sites spanning four continents. Across a variety of metrics, herbaceous v...

Fisheries bycatch is the greatest current source of human-caused deaths of marine mammals worldwide, with severe impacts on the health and viability of many populations. Recent regulations enacted in the United States under the Fish and Fish Product Import Provisions of its Marine Mammal Protection Act require nations with fisheries exporting fish and fish products to the United States (hereafter, “export fisheries”) to have o...
