On the Trails: A green world

Five decades ago, some well-known ecologists looked around and noted that their terrestrial world was very green. Why didn’t herbivores demolish the greenery? The observers… Continue reading

This photo shows a so-called "mummy berry." "The best-studied type of Monilinia attacks a blueberry species that is native to eastern North America but is also widely cultivated (e.g., in Pacific Northwest and British Colubmia)." writes Mary F. Willson. "When Monilinia vaccinii-corymbosi infests Vaccinium corymbosum, the vegetative parts are blighted and the fruits become hard, wizened 'mummy berries.'"
