When exploiting the environment, animals have to discriminate, track, and integrate salient
spatial cues to navigate and identify goal sites. Actually, they have to know what can be …

We present the theoretical and practical difficulties of inferring the cognitive processes
involved in spatial movement decisions of primates and other animals based on studies of …

Seed dispersal by frugivores is thought to play an important role in the maintenance of
tropical forest diversity. Spider monkeys (Ateles spp.) are amongst the most frugivorous …

Many wild primates occupy large home ranges and travel long distances each day.
Navigating these ranges to find sufficient food presents a substantial cognitive challenge …

Studies of interspecific competition and niche separation have formed some of the seminal
works of ecology. I conducted an 18-mo study comparing the feeding ecologies of 2 …

The first comprehensive field study of wild spider monkeys was undertaken in Panama in the
early 1930s by CR Carpenter. In discussing the diet of Ateles geoffroyi, Carpenter (1935) …

The multilevel society of hamadryas baboons, consisting of troops, bands, clans, and one‐
male units (OMUs), is commonly perceived to be an effective means of adapting to variable …

Mineral licks—also known as “salados,”“saladeros,” or “collpas”—are specific sites in
tropical and temperate ecosystems where a large diversity of mammals and birds come …

Ruffed lemurs (genus Varecia) are often described as having a flexible social organization,
such that both cohesive (low fission–fusion dynamics) and fluid (high fission–fusion …

Investigations of coevolutionary relationships between plants and the animals that disperse
their seeds suggest that disperser-plant interactions are likely shaped by diffuse, rather than …
