WING MORPHOLOGY OF A FOREST DAMSELFLY IS RELATED TO LANDSCAPE STRUCTURE

We demonstrate that, after correcting for the effects of size, the win g lengths, wing widths and thoracic weights of the forest damselfly Ca lopteryx maculata differ between populations along forested streams, a nd those along streams through pasture. Pasture landscapes can be cons idered as fragmented forest landscapes; forest landscapes are continuo us. In the fragmented landscapes some C. maculata fly across interveni ng pasture to reach foraging sites in forest. We propose that there is morphological plasticity within the species that is revealed through the landscape process of habitat fragmentation and that there is micro -scale selection within the fragmented landscapes for individuals that are better suited to make these flights.
