On the value of information: Studying changes in patch assessment abilities through learning

Article Abstract:

Some animals acquire and use prior information, particularly for Bayesian patch assessment strategies, as different patch assessment strategies rely upon distinct capabilities to obtain information. The results suggest that assessment abilities can change when exploiting novel but predictable patches, when degus can incorporate adequate environmental information, prior and current information may become accurate enough to make animals exploit patches efficiently.

How important is the statistical approach for analyzing categorical data? A critique using artificial nests

Article Abstract:

The statistical tests used to analyze artificial nest data within the framework of the generalized linear model are discussed. It is seen that the logistic regression is the most appropriate and flexible statistical test for analyzing binary data-sets.

Spite: altruism's evil twin

Article Abstract:

The evolution of spite is explained with the help of a game theory model. The conditions for the evolvement of spite are parallel to the conditions allowing the evolution of altruism.
