 As a result, animals have certain environmental and social cues that they can use to decide when is the most beneficial time to show such behaviours; they use these triggers to minimize cost (predator avoidance) and maximize gain (mate attraction).The first factor is temporal.Depending on the time of the season, animals (more specifically, tropical frogs, in this study) show strong seasonal trends in display behaviour favouring times closer to the beginning of the mating season.
