A Red-throated Loon swimming in a small lake

Does fish prey influence red-throated loon productivity?

This study will evaluate the nearshore marine feeding areas of breeding adult red-throated loons and assess the response of loon reproductive success to differences in the relative abundance, composition, and nutritional content of nearshore fish communities that vary in space and time.

Tracing Mercury Through Lake Food Webs

Mercury concentrations in fish likely reflect different energy sources in lake food webs. Species, populations, or individuals may contain higher and variable concentrations of mercury, which may relate directly to prey mercury content, diets of fish, and fish foraging strategies.

Energetic value of Arctic forage-sized fish with implications for a nearshore seabird predator Energetic value of Arctic forage-sized fish with implications for a nearshore seabird predator

Arctic cod (Boreogadus saida, also called polar cod) are considered the single most important Arctic forage fish due to their high abundance and nutritional quality. Because Arctic cod are strongly ice associated and prefer colder waters, their frequency in coastal waters has declined with warming, decreasing availability to nearshore predators. To consider the nutritional quality of...

Arctic fishes reveal patterns in radiocarbon age across habitats and with recent climate change Arctic fishes reveal patterns in radiocarbon age across habitats and with recent climate change

Climate change alters the sources and age of carbon in Arctic food webs by fostering the release of older carbon from degrading permafrost. Radiocarbon (14C) traces carbon sources and age, but data before rapid warming are rare and limit assessments over time. We capitalized on 14C data collected ~ 40 years ago that used fish as natural samplers by resampling the same species today...

Differential heat shock protein responses in two species of Pacific salmon and their utility in identifying heat stress Differential heat shock protein responses in two species of Pacific salmon and their utility in identifying heat stress

Rapid and accelerating warming of salmon habitat has the potential to lower productivity of Pacific salmon (Oncorhynchus species) populations. Heat stress biomarkers can indicate where warming is most likely affecting fish populations; however, we often lack clear classifications that separate individuals with and without heat stress needed to make these tools operational. We conducted a...

Borealization of nearshore fishes on an interior Arctic shelf over multiple decades Borealization of nearshore fishes on an interior Arctic shelf over multiple decades

Borealization is a type of community reorganization where Arctic specialists are replaced by species with more boreal distributions in response to climatic warming. The process of borealization is often exemplified by the northward range expansions and subsequent proliferation of boreal species on the Pacific and Atlantic inflow Arctic shelves (i.e., Bering/Chukchi and Barents seas...
