Historic plant collections offer a window into genetic change
A McGill University-led study published in BioScience demonstrates how digitized herbarium records can be used to reconstruct historical plant populations and monitor genetic diversity over centuries. The researchers argue that these collections are vital for understanding extinction risks and advocate for increased funding and digitization to support biodiversity conservation.

“Pressed plant specimens collected centuries ago and stored in herbaria around the world could play a key role in facilitating the tracking of genetic change and extinction risk in plants, a McGill University-led study indicates.”
SINGLE SOURCE
While web search results confirm that herbarium specimens are used to track ecological changes (e.g., heavy metals, climate change), there is no specific evidence in the provided results confirming a 'McGill University-led study' with these specific conclusions. The evidence is too general to corroborate the specific study attribution.
