Exaptation and emergence as mechanisms to cross fitness valleys during evolution: an example using simulated homing behaviour [PDF]

open access: yes, 2008
Evolution is often considered a gradual hill climbing process, slowly increasing the fitness of organisms. I investigate the evolution of homing behaviour in simulated intertidal limpets.

Optimal Foraging Theory and the Psychology of Learning

open access: yesAmerican Zoologist, 1983
The development of optimization theory has made important contributions to the study of animal behavior. But the optimization approach needs to be integrated with other methods of ethology and psychology. For example, the ability to learn is an important component of efficient foraging behavior in many species, and the psychology of animal learning ...

Predator Cues Reduce American Beaver Use of Foraging Trails

open access: yesHuman-Wildlife Interactions, 2017
Herbivores must balance energy needs with avoiding risks, using various cues to assess predation risk. The American beaver (Castor canadensis) is a semi-aquatic herbivore vulnerable to predation on land by wolves (Canis lupis).

The Advantage of Foraging Myopically

open access: yes, 2018
We study the dynamics of a \emph{myopic} forager that randomly wanders on a lattice in which each site contains one unit of food. Upon encountering a food-containing site, the forager eats all the food at this site with probability ...

Spatial clustering of hosts can favor specialist parasites

open access: yesEcology and Evolution
Generalist parasites seem to enjoy the clear ecological advantage of a greater chance to find a host, and genetic trade‐offs are therefore often invoked to explain why specialists can coexist with or outcompete generalists. Here we develop an alternative

Dietary divergence is associated with increased intra-specific competition in a marine predator

open access: yesScientific Reports, 2018
Optimal foraging theory predicts that when food is plentiful all individuals should take a small range of preferred prey types, but as competition increases less preferred prey will be included in the diet. This dietary switching may not be uniform among

Good Fences Make Good Neighbors: Adjacent Honey Bee Colonies Locally Partition Their Foraging Across Landscapes

open access: yesEcology and Evolution
Optimal foraging theory (OFT) predicts that animals employ foraging strategies that maximize a particular currency, such as net energetic efficiency, to meet their nutritional demands. Two nonexclusive patterns that arise from OFT are convergence on high‐

Do eagle owls select larger water voles?

open access: yesFauna Norvegica
Optimal foraging theory predicts that a hunter should hunt the energetically most profitable prey, often the larger size classes. The eagle owl is a formidable hunter of water voles.

Relationship between foraging behavior and predatory gain of Neoseiulus bicaudus under different prey densities

open access: yesBiological Control
Foraging behavior determines natural enemies’ predation capacity and biological control efficacy. Prey density significantly affects their foraging behavior. Studying predator foraging under different prey densities with movement process analysis reveals
