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 …

A focus of socioecological research is to understand how ecological, social, and life history
factors influence the variability of social organization within and between species. The …

Megaherbivores have pervasive ecological effects. In African rainforests, elephants can
increase aboveground carbon, though the mechanisms are unclear. Here, we combine a …

The question of whether any species except humans exhibits culture has generated much
debate, partially due to the difficulty of providing conclusive evidence from observational …

INTRODUCTION Relative to other great apes, humans have large brains, long life spans,
higher fertility and larger neonates, and protracted periods of childhood dependency and …

Animal foraging movements are shaped by sensory-motor abilities, availability and
distribution of resources and cognitive skills (memory of where, and possibly what and …

The earliest stone tool types, sharp flakes knapped from stone cores, are assumed to have
played a crucial role in human cognitive evolution. Flaked stone tools have been observed …

A bstract Spatial memory allows animals to retain information regarding the location,
distribution, and quality of feeding sites to optimize foraging decisions. Western gorillas …

Primate foraging is influenced by the spatial and temporal distribution of foods, which may
facilitate or constrain optimal nutrient intakes. Chimpanzees are frugivorous primates that …

The ecological-constraints model posits that living in larger groups is associated to higher
travel costs and reduced nutritional intake due to within-group feeding competition setting …
