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.

Habitat selection at low population densities

TL;DR: The results show that many of the patterns currently construed as supporting negative density-dependent habitat-selection models are also predicted by models that incorporate Allee effects or settlement costs and, more generally, suggest new approaches to habitat selection at low population densities.

Models of interference and their consequences for the spatial distribution of ideal and free predators

TL;DR: This paper compares the various ways applied so far of incorporating interference in Holling's functional response model and shows that the different models of interference result in qualitatively different predictions for 'ideal' and 'free' predators on the form of the aggregative response.

Consequences of adaptive behaviour for the structure and dynamics of food webs

TL;DR: Current knowledge supports ATB as an essential ingredient for models of community dynamics, and future research that incorporates ATB will be well positioned to address questions important for basic ecological research and its applications.

Emergent properties of conspecific attraction in fragmented landscapes

TL;DR: It is suggested that attraction can improve fitness when animals cannot directly assess habitat quality, and conspecific attraction influenced distributions by generating patch size effects and weak edge effects, highlighting that attraction is one potential, yet previously unappreciated, mechanism to explain the widespread patterns of animal sensitivity to habitat fragmentation.

Larval performance and oviposition site preference along a predation gradient

TL;DR: Experiments investigating both oviposition preference and larval performance in pinewoods treefrogs (Hyla femoralis) along a density gradient of predatory fish found that ovipositing H. Femoralis behaviorally partition available habitats into those with and without fish, largely matching the associated fitness consequences.

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.
