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

A risk-balancing trade off between foraging rewards and predation hazard in a shoaling fish
TL;DR: In controlled experiments, shoaling European minnows fed in equal numbers on two equally-rewarded food patches, and likewise on unequal patches the numbers feeding reflected food levels.

Getting beneath the surface of marine mammal – fisheries competition
TL;DR: It is argued that a pragmatic approach, which considers the effect of ecological complexity while avoiding the indiscriminate addition of detail to mathematical models of competition, is the best way to provide scientific advice on issues that require urgent action.

A new optimal transport distance on the space of finite Radon measures
TL;DR: In this article, a new optimal transport distance between nonnegative finite Radon measures with possibly different masses is introduced based on non-conservative continuity equations and a corresponding modified Benamou-Brenier formula.

Optimal diving under the risk of predation.
TL;DR: Diving behavior under the risk of predation at the surface is modeled to influence the optimal surface interval, regardless of whether foragers accumulate energy at a constant rate while at the food patch, deplete food resources over the course of the dive, or must search for food during the dive.

TL;DR: The lack of variance in vegetation structure across patch size during the early seres suggests that small mammal distributions were responding in large part to features of the system other than variance in Vegetation structure and composition acrossPatch size.

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.
