Evaluating the definition & distribution of spring ephemeral #wildflowers#AJB@ajyancy.bsky.social@benrlee.com@jmheberling.bsky.socialdoi.org/10.1002/ajb2...#botany#biodiversity
![On the left, a picture of a white wildflower (Trillium erectum) in early spring. A drop of water hangs from its lowest petal and blue skies can be seen in the background. On the right, the outline of eastern North America is overlaid with square grid cells shaded either red or blue, with 72 red cells (indicating regions where T. erectum was not found to be a spring ephemeral) and 7 blue cells (where it was found to have a spring ephemeral phenological strategy). Text on the image notes that the ephemerality index value assigned by the authors for this species is therefore 7/79 = 0.089.

Perfect timing as ephemerals come and go in the north temperate world! NSF REPS project of @ajyancy.bsky.social 😊🌸

Ok *now* it's starting to really look like an early spring - we are seeing plant response to the really warm winter and early spring, esp in the middle of the country. This is the 6-day forecast for the "start of spring," with some locations 4wks early now #phenologywww.usanpn.org/data/maps/spring
sad news - Duke University decided to dump their herbarium, which has over 800,000 plant specimens, one of the largest among in America, and includes many type specimens of Lady Gaga ferns. What a shame. Please stop Duke admins for making this horrible mistake!!
