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

Incentives for sustainable hunting of bushmeat in Rio Muni, Equatorial Guinea
TL;DR: Kumpel et al. as mentioned in this paper investigated the complex and dynamic interactions between market, hunter and prey along an entire bushmeat chain in continental Equatorial Guinea, thus enabling evaluation of the sustainability of the system under different policy scenarios.

Interspecific competition in small rodents: from populations to individuals
Jana A. Eccard,Hannu Ylönen +1 more
TL;DR: Recent research approaches to interspecific competition in rodents are reviewed based on census data and species assemblages, that use regression analysis, time series analysis, removal and exclusion experiments, and showcase their own experimental research on the effects of inter specific competition on individual life-history traits in boreal voles.

Interterritorial Habitat Variation in Grasshopper and Savannah Sparrows
TL;DR: Although these species occupied similar habitat situations after breeding populations stabilized in mid—June, they initially established territories in quite different portions of the habitat spectrum, with considerable inter—territorial variation in habitat features in both species.

Maladaptive Habitat Selection of a Migratory Passerine Bird in a Human-Modified Landscape
TL;DR: A case of maladaptive habitat selection in a farmland bird expanding its breeding range to human-created open habitats in plantations is demonstrated and the possible consequences for the population dynamics and persistence are discussed.

Deleting species from model food webs
TL;DR: In this paper, the authors used an evolutionary model to assemble many independent simulated food webs, and studied their dynamical behaviour when one species was deleted, finding that the larger the proportion of the deleted species in the predator's diet, the greater its probability of extinction.

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.
