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

Evolutionary consequences of asymmetric dispersal rates.
TL;DR: The model predicts that the population will be most likely to adapt to that habitat if the dispersal rates in both directions are high, highlighting the general message that the effect of gene flow upon local adaptation should depend profoundly on the demographic context of selection.

Long‐Term Demographic Responses of Trout Populations to Habitat Manipulation in Six Colorado Streams
Charles Gowan,Kurt D. Fausch +1 more
TL;DR: This research shows that log weirs increase trout abundance, but only if other management activities assure that fish dispersal remains unimpeded within the drainage, and detected a high degree of concordance in fish abundance fluctuations within and among streams.

Tests of density-dependent habitat selection in a patchy environment'
TL;DR: Regression and fitness tests were used to explore the pattern of density-dependent habitat use in two temperate-zone rodents and found habitat selection models appeared to be much less capable of predicting variation in population density.

Effects of social group size on information transfer and task allocation
TL;DR: Stochastic models show, at least in some cases, that the results described here occur even in small groups of approximately ten individuals.

Managing threatened species: the ecological toolbox, evolutionary theory and declining-population paradigm
TL;DR: It is argued that evolutionary theory underpins Caughley's declining-population paradigm, and that it needs to become much more widely used within mainstream conservation biology to help conservationists examine critically the reliability of the tools they have traditionally used to aid management decision-making.

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.
