How do meerkats use vocal signaling to maintain cohesion, coordinate and make decisions while on the move?  more

How does life in the canopy shape the evolution of the mind? The foraging decisions of kinkajous - an elusive species that forages in neo-tropical forest canopies at night - may offer some clues. The central aim of this project is to identify the processes of learning and memory that allow kinkajous to keep track of when and where to find their favorite food: fruit. By comparing our findings to what is known about primates, which also live in the canopy and eat fruit, we can gain a better understanding of the general ecological factors that lead to the evolution of greater intelligence. In turn, we may be able to identify how certain habitats facilitate the emergence of complex societies by selecting for brains that are better able to learn about relationships, be they social or spatial. more

To stay together, group-living animals must reach consensus about where to go and what to do. Because individuals differ in their needs and capabilities, group members’ preferences will not always align. Resolving such conflicts of interest is a key challenge to living in stable, socially complex societies. How is influence exerted? How is consensus achieved? more

Sleep is an inherently risky behavioral state, defined by decreased sensitivity to environmental stimuli. Sleeping together with other individuals offers a variety of advantages, including protection from predators and buffering against cold nighttime temperatures. However, group members also compete with each other over access to the safest, warmest, most comfortable sleeping spots, or the chance to sleep next to their preferred co-sleeping partners. Decisions about where to sleep are important, but assessing the options is complicated: the availability and quality of each position within the sleep site depends on the choices made by other group members. more
