Since that time, various prey-immobilizing toxins have evolved from innocuous proteins that were normally produced in other body tissues. Scientists believe that snakes, rather than simply tweak...

Expanding forests darken the outlook for butterflies, study shows

...student Nusha Keyghobadi used samples of butterfly dispersal and genetic variability taken from the Kananaskis region in Alberta to show a correlation between less genetic diversity and smaller meadows.

Diverse tropical forests defy metabolic ecology models

Some butterflies travel farther, reproduce faster
