Specimens used in the study came from the Natural History Museum, Oxford University Museum of Natural History, Tullie - Art Gallery, World Museum and National Museums Scotland. They were collected between 1890 and 2019.",

      "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.",
