Date

Data from ten papers were uploaded to the PREDICTS database today - our busiest day yet. During the day, we reached several landmarks - the 200th dataset, the 7,000th site, but perhaps the best were seeing the 2,000th beetle and the 1,000th true fly (Dipteran) go in. Despite having the lion's share of the world's species, arthropods are under-represented in many biodiversity indicators, largely because vertebrate species are so much better known. Of the 13,000 species in our database so far, nearly 8,000 are arthropods, 2,500 are higher plants, and under 2,000 are vertebrates, so hopefully our results will be a reasonable representation of what's happening; also, our sample sizes are large enough for us to test whether responses to human impacts differ among major clades.
