No trade-off between high and low temperature tolerance in a winter acclimatized Danish Drosophila subobscura population

摘要

Coping with cold winter conditions is a major challenge for many insects. In early spring we observed newly emerged Drosophila subobscura, which had overwintered as larvae and pupae. As temperatures increase during spring these flies are faced with higher minimum and maximum temperatures in their natural microhabitat Thus, there is a potential costly mismatch between winter and early spring acclimatization and the increased ambient temperatures later in adult life.
