We can finally release the first version of SPECTRE: standardized global spatial data on terrestrial SPECies ThREats. 24 layers at 1km2 resolution now available for all the world. https://t.co/Kol0XWXiSc Work developed @luomus, @CE3CResearch, @lasige with support @KoneenSaatio.
Take a look at SPECTRE, an #OA spatial database on global threats to terrestrial species and ecosystems. SPECTRE facilitates global change studies, species distribution modelling, threat assessments, among multiple other uses. https://t.co/7arXMUtR3z

The Late Pleistocene-Early Holocene saw massive human-linked #extinctions among #megafauna - but what happened to survivors? Based on genomics data for 139 extant megafauna, we show they experienced severe parallel declines as well @NatureComms 🦬🐘🐫🦒🦁

Nature Communications - Extinction of megafauna is a defining trend of the last 50,000 years. Here, the authors use genomic data to infer population histories of 139 extant megafauna, suggesting...

Continuing focused on the diversification team we studied also how dispersal modes affect Rhamnaceae diversification rates. Now out in Proceedings of the Royal Society B: Biological Sciences

Abstract. The evolution of dispersal modes has been proposed to promote the diversification of angiosperms. However, little is known about the relative imp

Overpublishing puts enormous stress on students and PIs. And brings tons of money to publishers in STEM. A new study shows that the number of papers is increasing FASTER than the number of #PhD graduates. It’s an amazing work with very useful statistics. Huge kudos to the

Our study on #butterfly #evolution, #hostplants & #ranges is now formally out! We built a phylogeny of 2000 sp and found butterflies originated in N. America 100M years ago, likely fed on legumes. ~100 scientists from 28 countries contributed. Thanks all!
