Habitat Selection of Two Sibling Species, Drosophila melanogaster and D. simulans : A Further Survey in the Bonin Islands(Ecology)

概要

A survey of the microdistribution of Drosophila in the Bonin Islands reconfirmed the earlier finding that D. melanogaster concentrated inside the building, while its sibling species, D. simulans, was abundant outside. A capture, mark, release and recapture study showed the unidirectional movement of each species ; from outside into the laboratory building for D. melanogaster and opposite direction for D. simulans. A comparative study between the laboratory building and farmer's storage sheds indicated the importance of human habitation for the concentration of D. melanogaster in man-made constructions. A multiple regression analysis of distribution data showed that the abundance of D. melanogaster was closely related with temperature and radiation factors at trapping sites and that of D. simulans was with luminosity.
