Biogeography of pelagic food webs in the North Pacific Biogeography of pelagic food webs in the North Pacific
The tufted puffin (Fratercula cirrhata) is a generalist seabird that breeds throughout the North Pacific and eats more than 75 different prey species. Using puffins as samplers, we characterized the geographic variability in pelagic food webs across the subarctic North Pacific from the composition of ~10,000 tufted puffin meals (~56,000 prey items) collected at 35 colonies in the Gulf of...

Avian predator buffers against variability in marine habitats with flexible foraging behavior Avian predator buffers against variability in marine habitats with flexible foraging behavior
How well seabirds compensate for variability in prey abundance and composition near their breeding colonies influences their distribution and reproductive success. We used tufted puffins (Fratercula cirrhata) as forage fish samplers to study marine food webs from the western Aleutian Islands (53°N, 173°E) to Kodiak Island (57°N, 153°W), Alaska, during August 2012–2014. Around each colony...

Tracing biogeochemical subsidies from glacier runoff into Alaska's coastal marine food webs Tracing biogeochemical subsidies from glacier runoff into Alaska's coastal marine food webs
Nearly half of the freshwater discharge into the Gulf of Alaska originates from landscapes draining glacier runoff, but the influence of the influx of riverine organic matter on the trophodynamics of coastal marine food webs is not well understood. We quantified the ecological impact of riverine organic matter subsidies to glacier-marine habitats by developing a multi-trophic level...

Best practices for assessing forage fish fisheries-seabird resource competition Best practices for assessing forage fish fisheries-seabird resource competition
Worldwide, in recent years capture fisheries targeting lower-trophic level forage fish and euphausiid crustaceans have been substantial (∼20 million metric tons [MT] annually). Landings of forage species are projected to increase in the future, and this harvest may affect marine ecosystems and predator-prey interactions by removal or redistribution of biomass central to pelagic food webs...

Puffins reveal contrasting relationships between forage fish and ocean climate in the North Pacific Puffins reveal contrasting relationships between forage fish and ocean climate in the North Pacific
Long-term studies of predator food habits (i.e., ‘predator-based sampling’) are useful for identifying patterns of spatial and temporal variability of forage nekton in marine ecosystems. We investigated temporal changes in forage fish availability and relationships to ocean climate by analyzing diet composition of three puffin species (horned puffin Fratercula corniculata, tufted puffin...

Influence of glacier runoff on ecosystem structure in Gulf of Alaska fjords Influence of glacier runoff on ecosystem structure in Gulf of Alaska fjords
To better understand the influence of glacier runoff on fjord ecosystems, we sampled oceanographic conditions, nutrients, zooplankton, forage fish and seabirds within 4 fjords in coastal areas of the Gulf Alaska. We used generalized additive models and geostatistics to identify the range of glacier runoff influence into coastal waters within fjords of varying estuarine influence and...
