The heterozygosity decline is Britain-wide, while the accompanying inbreeding signal is specifically emphasized for England and Wales and is not uniform across Britain. MEASUREMENT

Exact excerpt

Across Britain as a whole, the genetic diversity of moss carder bumblebees has declined steadily since the late nineteenth century, falling by around a quarter over the past 100 years. In England and Wales, this has been accompanied by an almost three-fold increase in the proportion of the genome affected by inbreeding. In contrast, populations in the Scottish Highlands appear to be less impacted by habitat fragmentation.
