Heat-hardening effects on mating success at high temperature in Drosophila melanogaster
Reproduction is strongly influenced by environmental temperature in insects. At high temperature, mating success could be influenced not only by basal (non-inducible) thermotolerance but also by inducible plastic responses. Here, mating success at high temperature was tested in flies carrying contra...

Reproduction is strongly influenced by environmental temperature in insects.
