A new paper in Proceedings of Royal Society B uses a massive data compilation of 162 datasets across the globe on fish, bird, and plant assemblages to ask how taxonomic and phylogenetic diversity has changed over time. Check it out here.
Also, the NASA bioXgeo working group co-led by Sydne has another publication out in a new book on remote sensing of plant diversity. The whole book is open access to promote open science! Check it out here.
