On territorial behavior and other factors influencing habitat distribution in birds
TLDR
In this article, the Dickcissel sex ratio is employed as an indirect index of suitability and a sex ratio index was found to be correlated positively with density, consistent with the hypothesis that territorial behavior in males of this species limits their density.Abstract:
This example is provided so that non-theorists may see actual applications of the theory previously described. The Dickcissel sex ratio is employed as an indirect index of suitability. A sex ratio index was found to be correlated positively with density. This is consistent with the hypothesis that territorial behavior in the males of this species limits their density. This study provides a valid example of how the problem can be approached and offers a first step in the eventual identification of the role of territorial behavior in the habitat distribution of a common species.read more

Evolutionary factors influencing the nature of parasite specificity
TL;DR: How specificity patterns are shaped during the course of parasite evolution is considered, which suggests that parasites may act as host generalists in hosts that act as trophic channels to the final host.

Fear factor: do dugongs (Dugong dugon) trade food for safety from tiger sharks (Galeocerdo cuvier)?
TL;DR: Dugongs appear to adaptively manage their risk of death by allocating time to safe but impoverished foraging patches in proportion to the likelihood of encountering predators in profitable but more dangerous areas, which has important implications for seagrass community structure in Shark Bay.

Breeding habitat selection in cliff swallows: the effect of conspecific reproductive success on colony choice
TL;DR: Cliff swallows probably use conspecific breeding performance in selecting colonies, one component of habitat selection that also includes attraction to Conspecifics and assessment of an individual's own success.

Is the home range concept compatible with the movements of two species of lowland river fish
TL;DR: In this paper, a radio-tracking study of golden perch (Macquaria ambigua) and carp (Cyprinus carpio) in the Broken River, Australia that aims to assess the home range concept as a means of describing the movements of these species.

Foraging in a fractal environment: Spatial patterns in a marine predator-prey system
TL;DR: Fractal geometry is explored as a possible tool for quantifying this view and for describing spatial dispersion patterns that result from foraging behavior and data on an Alaskan seabird and its zooplanktonic food resources suggest that fractal approaches can yield new ecological insights into complex spatial patterns deriving from animal movements.

Animal dispersion in relation to social behaviour
TL;DR: Wynne-Edwards has written this interesting and important book as a sequel to his earlier (1962) Animal Dispersion in Relation to Social Behaviour, and reviewing it has proven to be a valuable task for one who normally is only at the periphery of the group selection controversy.
