The physiological mechanisms underlying animal group dynamics. The project aims to provide novel insights into how individual differences in muscle biomechanics and metabolism constrain group assemblages, and the extent to which these constraints can cause fission and fusion of populations in changing environments. This research is significant because most ecological and evolutionary processes and their management occur at the level of groups.

The project aims to provide novel insights into how individual differences in muscle biomechanics and metabolism constrain group assemblages, and the extent to which these constraints can cause fission and fusion of populations in changing environments. This research is significant because most ecological and evolutionary processes and their management occur at the level of groups. The project expects to yield a theoretical model calibrated against empirical data to predict group dynamics of natural populations in changing environments, and of human crowds as diseases and lifestyle change physiological capacities.Read moreRead less
