Forced into an ecological corner: Round-the-clock deep foraging on small prey by elephant seals
Small mesopelagic fishes dominate the world’s total fish biomass, yet their ecological
importance as prey for large marine animals is poorly understood. To reveal the little-known …

Lightscapes of fear: How mesopredators balance starvation and predation in the open ocean
Like landscapes of fear, animals are hypothesized to strategically use lightscapes based on
intrinsic motivations. However, longitudinal evidence of state-dependent risk aversion has …

Fine-scale whisker growth measurements can reveal temporal foraging patterns from stable isotope signatures
Stable isotope analysis of slow-growing, metabolically inert tissues is a common method for
investigating foraging ecology in migratory animals, as direct observations of feeding are …
