Population biology of wild/feral honey bee colonies (Apis mellifera) in German forests (PhD project, sponsored by DBU)
The honey bee is usually considered as the domesticated insect managed for honey production and crop pollination, but Apis mellifera has generally always been a wild bee species, too. After our finding that wild/feral honeybee colonies still occur in German forests (Kohl and Rutschmann 2018) the critical question is whether these colonies form a self-sustaining population (as opposed to the feral "population" being maintained by the recurrent immigration of swarms from apiaries). To clarify this, we are monitoring in detail the population demography of feral colonies in several forest areas over multiple years. Furthermore, we investigate how feral honey bees relate to managed honeybees in terms of colony abundances, heritage, and health status.
