      "excerpt": "The study continuously monitored the tsunami-created Otsuchi population from 2012 through 2020, collecting 2,698 sticklebacks across changing numbers of ponds. Purging was analyzed at 667 species-diagnostic loci: 65 linked to reproductive-isolation QTL, 591 genomic-background loci, and 11 potentially advantageous loci. The generation produced in 2011 was defined as the first generation; the 2020 sample represented the tenth. Two other tsunami-struck habitats showed greater retained Gasterosteus nipponicus ancestry, and the study could not distinguish adaptive introgression from drift at some retained loci.",

  "searched": "Read the primary Nature Ecology & Evolution study’s abstract, time-series results, figures, discussion, and sampling/methods sections. Checked the focal population, sampling years and sizes, diagnostic-locus denominator, barrier-locus versus genomic-background comparison, generation definition, and replication in other tsunami habitats. The headline pattern is specific to the Otsuchi tsunami-created population; other tsunami habitats retained more marine ancestry, and the study reports unresolved alternatives at some retained loci."
