Evolutionary community ecology of biological invasion: a lesson from social insects

Organizer: Kazuki Tsuji (Univ. Ryukyus)

Dispersal of organisms plays a key role in ecology and evolution, from individual to ecosystem levels. Biological invasion, initially caused by human-mediated long-distance migration, provides an ideal opportunity to directly study ecological and evolutionary dynamics in action. We primarily focus on social insects as a model system because of their ecological dominance. We show that many other interesting biological processes, such as sex, altruism, symbiosis, competition, life history evolution and speciation, are included in tangled and fascinating ways in the dynamical processes caused by dispersal.
