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

Lifetime reproductive success and density- dependent, multi-variable resource selection
TL;DR: LRS was inversely associated with local density, which was highest along the coast, and reproductive benefits of selecting Agrostis/Festuca grassland diminished with increasing density, and the relevance of these results to the understanding of the spatial distribution of red deer abundance is discussed.

Prey distribution and patchiness: factors in foraging success and efficiency of wandering albatrosses
TL;DR: The unpredictability of the location of prey and the type of prey caught by Wandering Albatrosses indicate that the species has a unique foraging strategy compared to most seabirds, which generally concentrate in more predictable foraging areas.

Evolution restricts the coexistence of specialists and generalists: the role of trade-off structure.
TL;DR: It is demonstrated that ecological coexistence is less likely for species facing a trade‐offs between per capita reproduction in different habitats than when the trade‐off acts on carrying capacities alone and that coexistence cannot be reached through gradual evolution.

Seascapes of fear: evaluating sublethal predator effects experienced and generated by marine mammals
TL;DR: It is suggested that future studies quantify patterns of time allocation to measure sub lethal effects of predators on marine mammals, as well as the capacity of marine mammals to have sublethal effects on their own prey.

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.
