Understanding the structural complexity and the main drivers of animal
search behaviour is pivotal to foraging ecology. Yet, the role of uncertainty as a generative mechanism of
movement pattern is poorly understood. According to traditional views,
the lack of resource information result in the assumption that foraging
strategies are ballistic. On the contrary, novel insights from search
theory suggest that before resolving to relocate to another area,
organisms could also collect and assess new information from the
environment, unfolding complex exploratory strategies. Based on an
extension of the first passage time theory, we unveil elelmentary random
search principles that can be useful to frame the study of foraging
behaviour under uncertainty.
