Effects of predator confusion on functional responses

Article Abstract:

The first functional response model that considers confusion and compare it qualitatively as well as quantitatively to empirical data from two predator prey systems namely Aeshna cyanea-Daphnia magna and Chaoborus obscuripes-Daphnia obtusa. Since predator confusion is similar to other swarming effects that reduce predator foraging success, the models may not only reveal ecological evolutionary, and ethological consequences of predator confusion but of defense functions of gregariousness in general.

Interpatch movement and edge effects: The role of behavioral responses to the landscape matrix

Article Abstract:

A study of the role of behavioral responses to the landscape matrix by tracking the individual movements of planthoppers released at the edge of brome- mudflat-bordered cordgrass patches, and within homogeneous habitats of each type is presented. Dispersal success may be higher in brome matrix because tortuous movement through this matrix increases the planthopper's rate of encounter with cordgrass patches.

Intraspecific variation in movement patterns: modeling individual behavior in a large marine predator

Article Abstract:

The locations for 52 grey seals fitted with satellite-linked recorders on Sabe Island are used, and movement as a correlated random walk (CRW) for individual animals at two temporal scales is developed. The importance of intraspecific variation in the movement behavior in the grey seal's foraging ecology is stressed.
