From 1851 to 1858, Henry David Thoreau noted a number of natural occurrences in detail, including the first flowering dates for over 500 species of wildflowers in Concord. Additionally, Alfred Hosmer, a botanist in the same area
, had recorded the flowering dates
of over 600 species of wild plants in 1878 and from 1888 to 1902. With that data, Richard Primack
, a biology professor at Boston University, and fellow researcher Abraham Miller-Rushing
spent years aligning old plant names with current names to study the change flowering patterns
from the recorded past to present. Their phenological
study concluded that plants in Concord, on average, are now flowering 10 days earlier than they were in Thoreau's time

Gregory Colbert's Ashes and Snow
has been linked to twice before on Metafilter. However, you can now view 10 minutes
of his film as part of his Ted Talk--it's the most stunning nature footage I've ever seen. In the talk he also mentions a new concept he's developing called Animal Copyright
, which I think is long overdue.
