TLDR
A simple model shows that maximal energetic efficiency is associated with immediate consumption, whereas (under the field conditions studied) carrying items to the safety of trees provides for minimal exposure to predation.

Behavioral decisions made under the risk of predation: a review and prospectus

TL;DR: This work has shown that predation is a major selective force in the evolution of several morphological and behavioral characteristics of animals and the importance of predation during evolutionary time has been underestimated.
Journal ArticleDOI

Patch use as an indicator of habitat preference, predation risk, and competition

TL;DR: In this paper, a technique for using patch giving up densities to investigate habitat preferences, predation risk, and interspecific competitive relationships is theoretically analyzed and empirically investigated, and the technique was applied to a community of four Arizonan granivorous rodents (Perognathus amplus, Dipodomys merriami, Ammospermophilus harrisii, and Spermophilia tereticaudus).
Journal ArticleDOI

Predator vigilance and group size in mammals and birds: a critical review of the empirical evidence

TL;DR: Most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behaviour and group size, but many studies reveal interesting features of the relationship between Vigilance and Group size that should provide fruitful avenues for future research.

Habitat Selection Under Predation Hazard: Test of a Model with Foraging Minnows.

James F. Gilliam, +1 more
- 01 Dec 1987 - 
TL;DR: A model that specifies the choice of foraging areas ("habitats") that would minimize total mortality risk while allowing collection of some arbitrary net energy gain is presented and tested.

Food supplementation experiments with terrestrial vertebrates: patterns, problems, and the future

TL;DR: The typical population response to food supplementation was two- to three-fold increase in density, but no change in the pattern of population dynamics, which points to the need for researchers to conduct food supplementation experiments in tropical environments.

An Experimental Test of the Effects of Predation Risk on Habitat Use in Fish

TL;DR: Methods to predict the additional mortality expected on a cohort due to a reduction in growth rate are developed, and the potential for predation risk to enforce size—class segregation is discussed, which leads de facto to resource partitioning.

Introduction to Probability and Statistics

TL;DR: The twelve edition of the Introduction to Probability and Statistics (INTRODUCTION TO PROBABILITY and STATISTICS) as discussed by the authors has been used by hundreds of thousands of students since its first edition.

Foraging Efficiency and Body Size: A Study of Optimal Diet and Habitat Use by Bluegills

TL;DR: Habitat use of large bluegills was shown to maximize foraging return as fish switched from utilizing vegetation- living prey to utilizing open-water zooplankton as relative foraging profitabilities in the two habitats changed across the summer.
Journal ArticleDOI

Optimal behavior: can foragers balance two conflicting demands?

TL;DR: A backswimmer, Notonecta hoffmanni, was capable of balancing these two conflicting factors adaptively and was able to compare the observed behaviors with predictions derived from fitness considerations.
