Temperature effects on Florida applesnail activity: implications for snail kite foraging success and distribution [PDF]

open access: yes, 2002
The endangered Florida snail kite (Rostrhamlls sociaiJilis) feeds exclusively on applesnails (Pomacea pailiclosa), yet we lack direct observations that link applesnail behavior to snail kite foraging success.

The importance of termites (Isoptera) for the recycling of herbivore dung in tropical ecosystems: a review

open access: yesEuropean Journal of Entomology, 2008
While the key role of termites in the decomposition of litter in the tropics has been acknowledged for a long time, much less information exists on their importance in the recycling of dung of primary consumers, especially herbivores.

Foraging Behavior of Tetramorium Caespitum in an Urban Environment: the Effect of Food Quality on Foraging [PDF]

open access: yes, 2016
Animals\u27 foraging strategies are directly related to their fitness. Proposed models of optimal foraging assume that animals strategize in terms of maximizing benefits over the cost of acquiring resources. Ants are social insects that are comparable in

Why do many animals move with a predominance of roughly forward directions? [PDF]

open access: yes, 2010
Animal movements can influence their ecology and demographics. Animal movements are often characterized by path structures with directional persistence.

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 ...

Complex Behavior in Simple Models of Biological Coevolution

open access: yes, 2006
We explore the complex dynamical behavior of simple predator-prey models of biological coevolution that account for interspecific and intraspecific competition for resources, as well as adaptive foraging behavior.

Free-range pigs foraging on Jerusalem artichokes [PDF]

open access: yes, 2013
Free-range pig production in Northern Europe is characterized by high inputs of concentrate on grassland. This increases risk of nutrient leaching, increases feed costs and puts a pressure on land resources.
