The research compares rates of species evolution in three types of aquatic stream insects—mayflies (Ephemeroptera), stoneflies (Plecoptera) and caddisflies (Trichoptera) - in temperate and tropical mountain areas. The findings have implications for similar patterns in other tropical mountain species.

An interdisciplinary team of physiologists, geneticists and genomics specialists, population biologists and taxonomists from four universities gathered samples and data from mountain streams in the Colorado Rocky Mountains and in the Ecuadorian Andes over a two-year period.
