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

Does tiger shark predation risk influence foraging habitat use by bottlenose dolphins at multiple spatial scales
TL;DR: The results suggest that predation risk and prey availability influence dolphin habitat use at multiple spatial scales, but intrinsic habitat risk, and not just predator encounter rate, is important in shaping dolphin space use decisions.

The effect of conspecifics on habitat selection in territorial species
TL;DR: The results refute the commonly held assumptions that prospective territory owners avoid entering relatively full habitats, and that they prefer to settle in relatively unsaturated habitats.

TL;DR: Several multistratum capture-recapture models were used to test various hypotheses about possible geographic and temporal variation in survival, movement, and recapture/resighting probabilities of Roseate Terns (Sterna dougallii) color-banded from 1988 to 1992 at the sites of the four largest breeding colonies in the northeastern USA.

Foraging in a Hierarchical Patch System
TL;DR: The model suggests that tracking efficiency, defined as the forager's mean position within the system, increases for increasing prey abundance and maximum tracking efficiency is found at intermediate prey aggregations and thattracking efficiency decreases for aggregations above and below this point.

Choices and consequences of habitat occupancy and nest site selection in sage sparrows
TL;DR: In this article, the authors examined consequences of habitat choice in Sage Sparrows (Amphispiza belli) in southern California and found that the mean score of unsuccessful territories on a discriminant function describing the habitat gradient from unoccupied to occupied areas was significantly higher than the mean for successful ones.

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.
