    Happy to have contributed to a new estimate of the number of tree species on our planet, just out in @PNASNews. Our updated number is 73000 species, 14% more than currently known, w/ 9,200 species yet to be discovered 🌲🌳🌴🌍 pnas.org/content/119/6/… #trees #forests #macroecology

    One of the most fundamental questions in ecology is how many species inhabit the Earth. However, due to massive logistical and financial challenges...

    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 🦬🐘🐫🦒🦁

    The diversity & functioning of Europe's #mammal #fauna are strongly degraded relative to recent prehistoric baselines at similar climate - see our new @TERRANOVA4EU study @GEB_macro, led by @MarcoDavoli3 onlinelibrary.wiley.com/doi/10.1111/ge… 🐎🐘#defaunation #megafauna #Pleistocene #allometry

    Time to re-think what is a natural forest: Check our new study in @ScienceAdvances: Substantial light #woodland & open vegetation characterized the temperate #forest #biome before Homo sapiens science.org/doi/10.1126/sc… 🌳🌿🐘🦬🍃🌼 #Pleistocene #vegetation #megafauna

    Landscape reconstruction using pollen data shows that European temperate forests were open and heterogeneous before modern humans.

    Curious about the massive #extinction of #megafauna - eg #mammoth, #mastodon, #sabercats & #sloths - in recent #prehistory, as we show in a new synthesis, the pattern is strongly coupled to Homo sapiens & w/out any consistent link to #climatechange cambridge.org/core/journals/… 🦣🐘🦣

    What happened to #mammoths & #sabercats? Over the last ~50,000 years, #megafauna suffered severe #extinctions, e.g. only 11 of 57 #megaherbivores survived. Our review shows strong & increasing support for human causation + strong #ecosystem consequences rb.gy/17dlyx🦣

    Our new study showing that animal losses have severely reduced plants' capacity to track #climatechange worldwide is just out in @ScienceMagazine (& on the front page) 🐎🐾🌿🌴🌦️ Big thx @ecfricke for leading! #plants #dispersal #extinction #biodiversitycrisis #mammals #birds

    A key way plants adapt to climate change is through migration. But about half of plant species rely on animals for dispersal. Our (w @anordonez1 @haldre1 @JCSvenning) new paper asks how seed disperser losses impact plants' ability to track climate change. science.org/doi/10.1126/sc…
