Phys.org: Century-old botany records may hold key to monarch butterfly survival

Phys.org: Century-old botany records may hold key to monarch butterfly survival. “Naturalists’ records dating back more than 100 years may be instrumental in determining the fate of the monarch butterfly in the 21st century. Jack Boyle, a Mellon Postdoctoral Fellow of Environmental Science and Policy at William & Mary, has been using the web to mine millions of century-old botany records to track abundance patterns of milkweed in America. His hope is to solve the puzzle of how innovations in agriculture have affected the natural habitat for monarch butterflies. Using recently digitized herbaria records to get a picture of the past, Boyle aims to predict what the future may look like for milkweed.”
