About 62,000 dead or dying common murres (Uria aalge), the trophically dominant fish-eating seabird of North Pacific, washed ashore between summer 2015 and spring 2016 on beaches from California to Alaska. Most birds were severely emaciated and, so far, no evidence for anything other than starvation was found explain this mass mortality. Three-quarters in Gulf Alaska remainder along West Coast. Studies show that only a fraction die at sea typically wash ashore, we estimate total mortality...
Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, abundance, quality, distribution to explain distributions three co-occurring predator species breeding on islands southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed murres (Uria lomvia), northern fur seals (Callorhinus ursinus). Predictions statistical models were tested using movement patterns obtained from satellite-tracked...
Abstract Some of the longest and most comprehensive marine ecosystem monitoring programs were established in Gulf Alaska following environmental disaster Exxon Valdez oil spill over 30 years ago. These have been successful assessing recovery from impacts, their continuation decades later has now provided an unparalleled assessment responses to another newly emerging global threat, heatwaves. The 2014–2016 northeast Pacific heatwave (PMH) was lasting globally past decade, with some cooling,...
Abstract During the Pacific marine heatwave of 2014–2016, abundance and quality several key forage fish species in Gulf Alaska were simultaneously reduced throughout system. Capelin ( Mallotus catervarius ), sand lance Ammodytes personatus herring Clupea pallasii ) populations at historically low levels, within this community abrupt declines portfolio effects identify trophic instability onset heatwave. Although compensatory changes age structure, size, growth or energy content observed to...
Highly-threatened seabirds connect many countries and the high seas therefore depend on coordinated ocean governance.
Marine heatwaves are global phenomena that can have major impacts on the structure and function of coastal ecosystems. By mid-2014, Pacific Heatwave (PMH) was evident in intertidal waters northern Gulf Alaska persisted for multiple years. While offshore marine ecosystems known to respond these warmer waters, response rocky this warming is unclear. Intertidal communities link terrestrial their resources important predators human food recreation, while simultaneously supporting a growing...
Among the varied adaptations for avian flight, morphological traits allowing large-bodied albatrosses to capitalize on wind and wave energy efficient long-distance flight are unparalleled. Consequently, biogeographic distribution of most is limited windiest oceanic regions earth; however, exceptions exist. Species breeding in North Central Pacific Ocean (Phoebastria spp.) inhabit lower speed height than southern hemisphere genera, have large intrageneric variation body size aerodynamic...

Marine protected areas (MPAs), particularly large MPAs, are increasing in number and size around the globe part to facilitate conservation of marine megafauna under assumption that large-scale MPAs better align with vagile life histories; however, this alignment is not well established. Using a global tracking dataset from 36 species across five taxa, chosen reflect span home range highly mobile megafauna, we show most too small encompass complete ranges species. Based on alone, 40% existing...

Surface and subsurface moored buoy, ship-based, remotely sensed, reanalysis datasets are used to investigate thermal variability of northern Gulf Alaska (NGA) nearshore, coastal, offshore waters over synoptic century-long time scales. NGA sea surface temperature (SST) showed a larger positive trend 0.22 ± 0.10 °C per decade 1970–2021 compared 0.03 1900–2021. Over scales, SST covariance between two stations is small (<10%) when separation exceeds 100 km, while separated by 500 km retain 50%...
In the high seas, Pacific salmon (Oncorhynchus spp.) stocks exhibit considerable mixing across North Pacific, which increases potential for inter- and intra-species resource competition. Stock origin stock-specific phenotypic differences in feeding may therefore be an important factor understanding density dependence other drivers of nutritional quality. Evidence north have been shown from stable isotope analysis sockeye returns (Welch Parsons 1993; Johnson Schindler 2012), growth rates...
We investigated the efficacy of management to reduce impact Caspian tern (Sterna caspia) predation on survival juvenile salmonids (Oncorhynchus spp.) in Columbia River estuary. Resource managers sought relocate approximately 9,000 pairs terns nesting Rice Island (river km 34) East Sand 8), where were expected prey fewer salmonids. Efforts attract nest included creation habitat, use social attraction techniques, and predator control, with concurrent efforts discourage from Island. This...
Abstract We studied the diets, foraging strategies, and reproduction of Black-legged Kittiwakes (Rissa tridactyla) during five years at two colonies within Prince William Sound, Alaska. Years with reduced occurrence 1-year-old Pacific herring (Clupea pallasi) in kittiwake diets were associated increased trip duration, distance, travel time both colonies. Foraging range was consistently greater large, fjord colony an annual mean duration 4 hr distance to farthest feeding location 40 km when...

We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla) have caused shifts habitat use with direct implications population trends. To test this, we compared at-sea distribution, breeding performance, and nutritional stress of three years (2008-2010) at two sites the Pribilof Islands, where has either declined (St. Paul) or remained stable George). Foraging were assessed from (1) bird diets, (2) biomass distribution juvenile...
