Symposium 4: Phylogeny and Evolution of Bees: A Tribute to Charles Michener
Bees are one of the largest and most important groups of social insects. Bee social behavior spans a wide range, including solitary nesting, communal and semisocial interactions, cleptoparasitism, social parasitism, primitive and advanced forms of eusociality. Phylogenies provide the comparative framework for understanding social evolution in bees. The application of DNA sequencing and molecular systematics to bee phylogenetic studies has shed new light on bee phylogeny at all levels, from the relationships among families to relationships among closely related species. This symposium will present talks on new insights gained from these studies, and will honor the contributions of Dr. Charles Michener to studies of bee phylogeny and social evolution.
