Whole-genome sequencing of 26 Finnish Aquila chrysaetos across 136 years shows drastic post-bottleneck genetic erosion, including an 82% reduction in genome-wide heterozygosity.
- Why it matters: Human persecution caused a mid-20th-century bottleneck, but the long-term genomic consequences during demographic recovery in Finland were unclear.
- What they did: The study analyzed whole-genome data spanning before, during, and after the 1950–1960s low point, using diversity metrics (heterozygosity, nucleotide diversity, Watterson’s theta), site frequency spectrum, Tajima’s D, and runs of homozygosity.
- The result: Diversity loss and elevated post-bottleneck inbreeding indicate strong genetic erosion despite census recovery, supporting genomic indicators and regional assessments for conservation monitoring.
