Summing the strokes: energy economy in northern elephant seals during large-scale foraging migrations. [PDF]
, 2015 BackgroundThe energy requirements of free-ranging marine mammals are challenging to measure due to cryptic and far-ranging feeding habits, but are important to quantify given the potential impacts of high-level predators on ecosystems.

Fuelling on the wing: sensory ecology of hawkmoth foraging [PDF]
Journal of Comparative Physiology A, 2019 Hawkmoths (Lepidoptera, Sphingidae) comprise around 1500 species, most of which forage on nectar from flowers in their adult stage, usually while hovering in front of the flower. The majority of species have a nocturnal lifestyle and are important nocturnal pollinators, but some species have turned to a diurnal lifestyle.

Multidimensional nutritional ecology and urban birds
Ecosphere, 2018 There is growing interest in the question of how urbanization affects the ecology of birds, across timescales from relatively short‐term physiological responses to long‐term evolutionary adaptation.

Fine-scale foraging ecology of leatherback turtles
Frontiers in Ecology and Evolution, 2015 Remote tracking of migratory species and statistical modeling of behaviors have enabled identification of areas that are of high ecological value to these widely distributed taxa.

Foraging mode affects extinction risk of snakes and lizards, but in different ways
Conservation Letters, 2023 What factors render a species more vulnerable to extinction? In reptiles, foraging mode is a fundamental ecological dimension: some species actively search for immobile prey, whereas others ambush mobile prey. Foraging mode is linked to diet, morphology,

Decision ecology: Foraging and the ecology of animal decision making [PDF]
Cognitive, Affective, & Behavioral Neuroscience, 2008 In this article, I review the approach taken by behavioral ecologists to the study of animal foraging behavior and explore connections with general analyses of decision making. I use the example of patch exploitation decisions in this article in order to develop several key points about the properties of naturally occurring foraging decisions. First, I

Ecological Consequences of Foraging Mode [PDF]
Ecology, 1981 Desert lizards are typically either widely foraging or sit—and—wait predators, and these foraging modes are correlated with major differences in ecology. Foraging mode is related to the type of prey eaten by lizards. Widely foraging lizards in the Kalahari desert, the Western Australian desert, and the North American desert generally eat more prey that

How animals distribute themselves in space: energy landscapes of Antarctic avian predators
Movement Ecology, 2021 Background Energy landscapes provide an approach to the mechanistic basis of spatial ecology and decision-making in animals. This is based on the quantification of the variation in the energy costs of movements through a given environment, as well as how
