How animals distribute themselves inspace: energy landscapes of Antarctic avian predators

[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 agiven environment, as well as how these costs vary in time and for different...

Descripción
Sumario:[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 agiven environment, as well as how these costs vary in time and for different animal populations. Organisms asdiverse as fish, mammals, and birds will move in areas of the energy landscape that result in minimised costs andmaximised energy gain. Recently, energy landscapes have been used to link energy gain and variable energy costsof foraging to breeding success, revealing their potential use for understanding demographic changes.
