Intrafamilial resource competition and mate competition shaped social-group-specific natal dispersal in the 18th and 19th century Krummhorn population

We describe the natal dispersal patterns of the Krummhorn population as the outcome of intrafamilial competition. Depending on the affiliation with a specific social group and the sex of the individual, this competition is driven by different factors and obeys a different functional logic: The dispersal patterns of the daughters of landless workers allow a mate competition scenario to be detected, whereas the dispersal behavior of the children of farmers (especially of the sons) is driven by a resource competition scenario.
