Scientists Use DNA Sequencing to Help Ecosystems Adapt to Rapid Climate Change
Climate change is occurring far faster than natural evolution can accommodate, threatening vital ecosystems such as California’s redwoods and coastal seagrass meadows. To address this mismatch, scientists are employing conservation genomics, an emerging discipline that sequences organisms' genetic blueprints to identify individuals with traits suited for surviving drought, disease, and extreme heat. Researchers at the Salk Institute for Biological Studies in San Diego are applying these techniques to eelgrass, which plays a crucial role in carbon storage and marine habitat support. Traditional restoration efforts for eelgrass often fail due to warming waters and sediment disruption from king tides. By pinpointing resilient genetic variants, scientists aim to guide more effective restoration projects. Similar genomic tools are being used globally to help coral reefs recover from mass bleaching caused by marine heat waves. This approach represents a critical intervention to prevent the extinction of approximately one million species currently at risk due to human activities and accelerating environmental changes. The integration of advanced DNA sequencing technology offers a promising strategy to bolster ecosystem resilience against the rapid impacts of global warming.
