Learning to Cope With Two Different Food Distributions: The Performance of House Mice (Mus musculus domesticus)
Search abilities of mice ( Mus musculus domesticus ) were evaluated using an arena closed by a ceiling in which 9 food sources (which mice could reach standing on their hind legs) could be arranged according to 2 configurations: a 3×3 square matrix and 3 clusters each containing 3 food sources. Testing conditions prevented olfactory […]
Spatial navigation strategies in Peromyscus: a comparative study
A male advantage in spatial abilities is predicted to evolve in species where males rely on expansion of home territory to locate dispersed mates during the breeding season. We sought to examine mechanistic underpinnings of this evolved trait by comparing spatial navigational abilities in two species of Peromyscus that use widely different reproductive strategies: deer […]
Must marine predators always follow scaling laws? Memory guides the foraging decisions of a pursuit-diving seabird
Foraging animals are expected to adapt their movement patterns to their environment in a way that maximizes efficiency. The search strategies they rely on to achieve this is an enduring question in ecology. Scale-free Lévy and Brownian search strategies have received particular attention as both strategies are considered effective when prey are abundant and Lévy […]
