Long-term monitoring tells a story of change. For 80 years scientists have monitored Windermere and nearby lakes in Cumbria, tracking how climate change and pollution are reshaping our freshwater ecosystems.

We sequenced the genome of the Phytophthora infestans from that particular historical sample back in 2013 to characterize the genetic makeup of the strain that cause the pandemic outbreak of potato late blight. elifesciences.org/articles/00731 @kamounlab.bsky.social
The rise and fall of the Phytophthora infestans lineage that triggered the Irish potato famine
The strain of Phytophthora infestans that caused the Great Famine in the late 1840s was caused by a single genotype that is distinct from, but closely related to, the most prevalent modern genotype.

A carved Welsh slate model bureau
North Wales circa 1880
Similar pieces of folk art were carved by quarrymen of North Wales and most date from the late 19th century. Many were probably made to decorate their own homes and were given as gifts or entered into competition at local eisteddfodau.
