Oxidative damage is predicted to be a mediator of trade-offs between current reproduction
and future reproduction or survival, but most studies fail to support such predictions. We …

Energy expenditure in wild animals can be limited (i) intrinsically by physiological processes
that constrain an animal's capacity to use energy,(ii) extrinsically by energy availability in the …

Timing reproduction to overlap with peak prey availability is vital to success for many
species. This may be especially true for species that rely on one or a few prey species that …

The ability to efficiently measure the health and nutritional status of wild populations in situ is
a valuable tool, as many methods of evaluating animal physiology do not occur in real-time …

Seabird parents during chick rearing is hypothesized to regulate body mass to reduce flight
costs and invest energy in current reproduction. Alcids have 2‒4 times higher wing-loading …

DNA metabarcoding and stable isotope analysis have significantly advanced our
understanding of marine trophic ecology, aiding systematic research on foraging habits and …

The Coats Island field station in northern Hudson Bay, Canada, was established by the
Canadian Wildlife Service in 1984 to monitor the thick-billed murre (Uria lomvia, akpa,) …

The ability to store energy endogenously is an important ecological mechanism that allows
animals to buffer predictable and unpredictable variation in allostatic load. The secretion of …

Energy is a common currency for any living organism, yet estimating energy expenditure in
wild animals is challenging. Accelerometers are commonly used to estimate energy …

Thyroid hormones affect in vitro metabolic intensity, increase basal metabolic rate (BMR) in
the lab, and are sometimes correlated with basal and/or resting metabolic rate (RMR) in a …
