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

Can models of presence‐absence be used to scale abundance? Two case studies considering extremes in life history
TL;DR: Results from the two-process models suggest that distribution and abundance may be a function of different processes, and environmental factors influencing abundance may differ from those limiting distribution.

Social information trumps vegetation structure in breeding-site selection by a migrant songbird
TL;DR: It is hypothesized that post-breeding song is a pervasive and reliable cue for species that communicate vocally, inhabit temporally autocorrelated environments, produce young asynchronously and/or abandon territories after reproductive failure.

TL;DR: This work emphasizes the communication of the conceptual simplicity and underlying unity of ideas inherent in continuous-trait game theory and the development of new applications to biological questions.

Long-term reproductive output in western gulls: consequences of alternate tactics in diet choice
TL;DR: A strong, positive relationship existed among the amount of fish taken, breeding life-span, and reproductive performance, and the principal trait influencing both survival and reproduction was individual diet, which consisted of a mix of human refuse and fish.

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.
