Climate change isolates Rocky Mountain butterflies
...on for the alpine butterflies, said Jens Roland, a biological
scientist at the University of Alberta. The alpine Apollo butterfly (Parnassius) inhabits open meadows because they, like other types of butterflies, need sunlight to generate enough body heat in order to fly, and forests are generally too shady fo...
Unravelling new complexity in the genome
