Although many descriptive studies of foraging mode have been performed, the factors that underlie the evolution of foraging mode remain poorly understood. To test the hypothesis that foraging mode evolution is affected by ...

1. In environments in which resources are distributed heterogeneously, patch choice and the length of time spent on a patch by foragers are subject to strong selective pressures. This is particularly true for parasitoids ...

Three fundamental foraging patterns in air-breathing marine vertebrates have been described: epipelagic, mesopelagic and benthic. Many sea lion species with access to extensive continental shelves have been described as ...

Studies of the foraging behaviour of birds allow exploration of the mechanisms that structure species assemblages. The major objective of this study was to describe relationships among various components of foraging behaviour ...

The choice of foraging strategies implies an attempt at gaining energy by predators. Supposedly, the difference in employing the "sit and wait" or "active foraging" behavior lays in hunter skills, experience and the kind ...

Specimens of Tropidurus jaguaribanus were collected as part of a study of their use of microhabitats, activity period, body temperature, diet, foraging, sexual dimorphism (in size and in form), reproductive biology, and ...

We studied the availability and use of breeding habitat by Red-legged Cormorants (Phalacrocorax gaimardi) to identify the factors involved in habitat selection. The species nests on cliff-faces. We identified cliffs suitable ...

Wave exposure and habitat complexity have been used to explain variations in the distribution patterns and behavior of many reef fishes. This study analyzed the influence of both factors on density and foraging ...
