Research Interests

The Cook lab takes a holistic approach to understand social behavior. We aim to explain why and how collective behavior occurs at every level; from the collective, to individual behavior, to the physiology and genetics of the individual. Ecological context is critical for understanding social behaviors, so we also explore the environmental conditions that elicit many social behaviors, such as the need for food or a change in temperature.

General research framework in the Cook Lab

Honey bees are an excellent model system to explore questions about collective behavior. Honey bees perform many collective behaviors, including foraging and thermoregulation. Individual honey bees are incredibly smart and can be trained just like dogs! The mechanisms of behavior are well defined in honey bees, and the genome is well mapped. Finally, honey bee colonies exist in many different environments, which allows for us to understand the ecological importance of collective behaviors, and how information may be communicated as environmental conditions shift. Right now, we are focused on two main research areas:

Honey Bee Thermoregulation: Honey bees strictly regulate the temperature of their colony. When it is cold, honey bees shiver to keep developing brood and the queen warm. When it is hot, honey bees and circulate cool air into the colony by fanning. Fanning is performed by a relatively small task group (3-50 bees) but is critical behavior for the survival of the colony, as overheated larvae can die. When bees are in larger groups, they are more likely to fan, and fan at lower temperatures, compared to when bees are in small groups or in isolation. A major question that we aim to answer is what information are bees using and communicating to know when to fan?

 

Social Isolation: From egg to death, honey bees constantly interact with other bees. Anecdotal evidence shows that when bees are isolated for too long, even with all the food and water they need, they will die. Research in our lab will focus on exploring the physiology and behavioral implications of social isolation.

 

The Cook lab commits to developing an inclusive and supportive space to do the best science we can.
