Concepts

The finite time and energy budget forcing organisms to trade off between competing activities like foraging and vigilance

Natural selection that favors behaviors that benefit relatives, even at a cost to the individual performing the behavior

Correlations between multiple repeatable, individually distinct behaviors that form consistent behavioral patterns across situations

Fitness benefits that include both direct fitness (individual's own reproductive success) and indirect fitness (fitness gained by helping relatives reproduce), weighted by coefficient of relatedness

Signals that meet criteria of stimulus-class specificity and contextual independence, where alarm calls are said to be functionally referential when there is tight association between predator type an...
