Nearshore Marine Ecosystem Research
Nearshore ecosystems include many resources that are of high ecological, recreational, subsistence, and economic value. They also are subject to influences from a wide variety of natural and human-caused perturbations, which can originate in terrestrial or oceanic environments. Our research is designed to evaluate sources of variation in the nearshore and how they influence resources of high...

Lack of strong responses to the Pacific marine heatwave by benthivorous marine birds indicates importance of trophic drivers
The Pacific marine heatwave (PMH) of 2014-2016 was an intense, long-lasting environmental disturbance expressed throughout the north Pacific. While dramatic consequences of the PMH on pelagic food webs have been well documented, effects on nearshore food webs, i.e., those based on macroalgae primary productivity, benthic invertebrate intermediate consumers, and specialized benthivorous top predato

Revealing the extent of sea otter impacts on bivalve prey through multi-trophic monitoring and mechanistic models
Sea otters are apex predators that can exert considerable influence over the nearshore communities they occupy. Since facing near extinction in the early 1900s, sea otters are making a remarkable recovery in Southeast Alaska, particularly in Glacier Bay, the largest protected tidewater glacier fjord in the world. The expansion of sea otters across Glacier Bay offers both a challenge to monitoring

Where land and sea meet: Brown bears and sea otters
In Katmai National Park, Alaska, USA, we have seen changes in the number of brown bears and sea otters. The number of animals of a species a habitat can support is called carrying capacity. Even though bears live on land and sea otters live in the ocean, these two mammals share coastal habitats. Bears eat salmon, other fish, plants, clams, and beached whales. Sea otters feed on clams and other mar

Divergent gene expression profiles in Alaskan sea otters: An indicator of chronic domoic acid exposure?
An opportunistic investigation into ecosystem instability in Kachemak Bay (KBay), Alaska, has led us to investigate exposure to toxic algae in sea otters. We used gene expression to explore the physiological health of sea otters sampled in KBay in May 2019. We found altered levels of gene transcripts in comparison with reference sea otters from clinically normal, oil-exposed, and nutritionally cha

Timelines and mechanisms of wildlife population recovery following the Exxon Valdez Oil Spill
In March 1989, the T/V Exxon Valdez ran aground in Prince William Sound (PWS), Alaska and spilled an estimated 42 million liters of crude oil (Wolfe et al. 1994). This oil subsequently spread over more than 26,000 km2 of water surface in PWS and the Gulf of Alaska and landed on more than 1000 km of shoreline (Spies et al. 1996, Short et al. 2004; see Fig. 1 in Esler et al., this report).
