Hawaiian picture-winged exhibit adaptive population divergence along a narrow climatic gradient on Hawaii Island.

Anthropogenic influences on global processes and climatic conditions are increasingly affecting ecosystems throughout the world.Hawaii Island's native ecosystems are well studied and local long-term climatic trends well documented, making these ecosystems ideal for evaluating how native taxa may respond to a warming environment.This study documents adaptive divergence of populations of a Hawaiian picture-winged , that are separated by only 7 km and 365 m in elevation.
