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

Habitat selection by dispersing yellow-headed blackbirds: evidence of prospecting and the use of public information.

TL;DR: This study suggests that individuals prospect for potential breeding sites late in the breeding season when they can use information gathered from the reproductive success of other individuals (i.e., public information) to select a breeding site.

Transient dynamics of invasive competition: barred owls, spotted owls, habitat, and the demons of competition present.
TL;DR: A strong, negative association between Barred Owls detections and colonization rates and a strong positive effect of Barred Owl detections on extinction rates of Spotted Owls are observed.

Stochasticity in Bird Habitat Selection: Year-to-Year Changes in Territory Locations in a Boreal Forest Bird Assemblage
TL;DR: In this paper, the authors studied the degree of apparently stochastic variation in the location of the breeding territories of 17 species of birds in a 36-ha study plot in a heterogeneous coniferous forest in southern Finland over six consecutive years.

The foraging benefits of information and the penalty of ignorance
Ola Olsson,Joel S. Brown +1 more
TL;DR: This paper reconciles Bayesian foraging with cost–benefit theories and defines the difference between potential and instantaneous quitting harvest rates as the foraging benefit of information, FBI, for clumped prey.

The Role of Density Dependence in a Marine Infaunal Community
TL;DR: A spacing hypothesis is proposed which predicts that Pygospio relocates as often as necessary to minimize contact with Pseudopolydora, and Static spatial data from the field provide some support for the hypothesis.

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.
