Local scientists are using DNA to track evolution's progress against climate change, which is killing some of the planet's most vital ecosystems, such as California's towering redwoods and seagrass meadows. The issue is particularly acute as climate change accelerates due to extreme temperatures, record wildfires, and coastal development. Scientists are using conservation genomics, which can identify individuals with traits suited to survive drought, disease, and other climate extremes, to guide restoration efforts. Coral reefs are among the first ecosystems where these tools are being used. Researchers have identified colonies that naturally withstand higher temperatures and are beginning to test whether selectively breeding and growing these more resilient corals can support reef recovery. Researchers are applying the approach to eelgrass, a type of seaggrass, as traditional restoration methods falter.
