Study shows how aspen forests maintain the diversity needed to adapt to changing environments

A new decade-long study by University of Wisconsin­–Madison researchers, including Botany’s Ken Keefover-Ring, reveals how aspen stands change their genetic structure over the years as trees balance defending themselves from pests with growth to compete for sunlight. The findings are valuable for conservation biologists who want to preserve diverse forest ecosystems in the face of global warming, invasive species and other environmental changes.
