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

Individual-based models and the individual-based approach to population ecology
TL;DR: The need for clear distinctions between individual variation, skewness, asymmetric competition and monopolization of resources is discussed in this paper, since these concepts are fundamental to understanding population stability.

Time sharing between host searching and food searching in parasitoids: state-dependent optimal strategies
Etienne Sirot,Carlos Bernstein +1 more
TL;DR: The results suggest that under conditions of very low food availability, parasitoids should never search for food and that optimal time sharing between food searching and host searching may promote the stability of the host-parasitoid system.

Modeling zooplankton dynamics
TL;DR: The chapter aims to present detailed, specific applications of models on bioenergetics or demography of zooplankton, rather than a general mathematical study of modeling.

Where to catch a fish? The influence of foraging tactics on the ecology of bottlenose dolphins (Tursiops truncatus) in Florida Bay, Florida

TL;DR: This study demonstrates how foraging behavior can be an ecological determinant of overall dolphin habitat use patterns and works to create spatial structure within a population due to consistent mapping of tactics onto environmental variation.

Population Biology of the Yellow-Breasted Chat (Icteria Virens L.) in Southern Indiana

TL;DR: A population of color—banded Yellow—breasted Chats was studied during the breeding seasons of 1966 through 1970 on 18 ha of upland deciduous scrub habitat near Bloomington, Monroe County, Indiana, with low productivity resulted from a combination of nest predation and early cessation of reproductive activities in some years.

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.
