Genomic offsets in Macrocystis tenuifolia strongly predicted observed population declines along the British Columbia and Washington coasts, enabling a risk-of-extirpation metric under global change.
- Why it matters: Genomic tools can forecast responses to warming, but predictions are rarely validated against field outcomes, limiting conservation use.
- What they did: Using whole-genome data from 598 individuals across 94 sites and 37 environmental variables, the authors applied seascape genomics with gradient forests to model genetic turnover and estimate genomic offsets under projected conditions.
- The result: Offsets varied greatly among regions and explained contrasting local vulnerability; for Macrocystis tenuifolia they validated the genomic-to-outcome link, while for Nereocystis luetkeana offsets did not predict declines well, and models suggest short-distance assisted migration could attenuate vulnerability.
