'Shoebox' Satellites Help Scientists Understand Trees and Global Warming

As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental ...

Older Trees Accumulate More Mutations Than Their Younger Counterparts

A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived ...

The Other Side of the Story: How Evolution Impacts the Environment

Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas.
