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

Delayed dispersal: living under the reign of nepotistic parents
TL;DR: Although that association between delayed dispersal and cooperative breeding indicates that delayed disperseal is a permissive factor for the maintenance of cooperative breeding, there is not necessarily a causation going in the opposite direction.

Fire is a key element in the landscape-scale habitat requirements and global population status of a threatened bird: the Mallee Emu-wren (Stipiturus mallee).
TL;DR: The Mallee Emu-wren (Stipiturus mallee) is a threatened, narrow-range passerine endemic to south-eastern Australia as discussed by the authors, which is a habitat specialist, primarily occurring in mallee-Triodia vegetation.

Effects of sex-associated competitive asymmetries on foraging group structure and despotic distribution in Andean condors
José A. Donázar,Alejandro Travaini,Olga Ceballos,Alejandro Rodríguez,Miguel Delibes,Fernando Hiraldo +5 more
TL;DR: The results support most of the assumptions and predictions of the phenotype-limited distribution model, although a spatial truncated distribution between phenotypes was not observed and asymmetric feeding pay-off, unequal parental roles and sexual selection constraints could favour sexual divergence in body size in Andean condors.

Bird behaviour and environmental planning: approaches in the study of wader populations
TL;DR: Behaviour is the main way in which birds respond to environmental changes and compete for limited resources, such as diminishing habitat, and is likely to provide insights when making predictions about the responses of birds and populations to habitat loss.

Conspecific Attraction and Shelter Selection in Gregarious Insects
TL;DR: This study examined the interactive influence of conspecific attraction on individual resource preferences on refuge choice in groups of cockroaches and proposed a general framework for understanding how similar mechanisms can promote the skewed distribution of organisms at different spatial scales.

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.
