Critical photoperiods of the mosquito W. smithii

Graph: Critical photoperiods of the mosquito W. smithii

Caption: Critical photoperiods of the mosquito W. smithii collected during the overwintering generation from 1972 to 1996 (presentation version of the data figure from PNAS article). The genetic shift towards shorter,more southern critical photoperiods represents an adaptive response to longer growing seasons as a consequence of recent, rapid global warming. This genetic shift is detectable over as short a time as five years. "This is evolution at breakneck speed!"
