Pacific Salmon in Hot Water: Applying Aerobic Scope Models and Biotelemetry to Predict the Success of Spawning Migrations
Concern over global climate change is widespread, but quantifying relationships between temperature change and animal fitness has been a challenge for scientists. Our approach to this challenge wasExpand

Energetics and morphology of sockeye salmon: effects of upriver migratory distance and elevation
Depending on population, wild Fraser River sockeye salmon Oncorhynchus nerka travel distances of 1100 km and ascend elevations ranging from near sea-level to 1200m to reach spawning areas.Expand

Corticosterone Predicts Foraging Behavior and Parental Care in Macaroni Penguins
Corticosterone has received considerable attention as the principal hormonal mediator of allostasis or physiological stress in wild animals. More recently, it has also been implicated in theExpand

Upper ocean carbon export, horizontal transport, and vertical eddy diffusivity in the southwestern Gulf of Maine
The naturally occurring radionuclides 234Th and 7Be were used to investigate the magnitude of upper ocean particulate organic carbon export and the rate of vertical eddy di!usion in the southwesternExpand

Exposure to high temperature influences the behaviour, physiology, and survival of sockeye salmon during spawning migration
Since 1996, some populations of Fraser River sockeye salmon (Oncorhynchus nerkaWalbaum in Artedi, 1792) have begun spawning migrations weeks earlier than normal, and most perish en route as a result.Expand

Effect of water temperature, timing, physiological condition, and lake thermal refugia on migrating adult Weaver Creek sockeye salmon (Oncorhynchus nerka)
We coupled physiological biopsy and positional telemetry to examine survival to reach spawning grounds in re- lation to water temperature, timing, physiological condition, and holding location (riverExpand

Biological carryover effects: linking common concepts and mechanisms in ecology and evolution
The term 'carryover effect' originally arose from repeated measures clinical experiments. However, the term has more recently been applied to ecological and evolutionary studies, often in migratoryExpand

Coupling non‐invasive physiological assessments with telemetry to understand inter‐individual variation in behaviour and survivorship of sockeye salmon: development and validation of a technique
Approximately 200 km from the mouth of the Fraser River, British Columbia, Canada, adult sockeye salmon Oncorhynchus nerka, were gastrically implanted with radio transmitters without anaesthetic.Expand

Pollution, habitat loss, fishing, and climate change as critical threats to penguins.
Cumulative human impacts across the world's oceans are considerable. We therefore examined a single model taxonomic group, the penguins (Spheniscidae), to explore how marine species and communitiesExpand

A Nonlethal, Rapid Method for Assessing the Somatic Energy Content of Migrating Adult Pacific Salmon
Abstract Traditional methods for determining the energy content of fish involve either chemical assays of lipid and protein levels (proximate analyses) or tissue combustion (bomb calorimetry). InExpand
