Although many ecosystems can weather several years of moderate drought, consecutive years of extreme dryness push them past a tipping point, resulting in dramatic declines in plant growth, researchers report in Science. https://scim.ag/4ogN9I8
Drought intensity and duration interact to magnify losses in primary productivity
As droughts become longer and more intense, impacts on terrestrial primary productivity are expected to increase progressively. Yet, some ecosystems appear to acclimate to multiyear drought, with cons...

Working with individual trait data and functional trait spaces and bored about means?

With @cpcarmona.bsky.social, Agnese Bissi and @etordoni.bsky.social, we put together a perspective to test the effect of individual observations on trait space properties 👇👇

Excited to share our new open-access review led by Francesco de Bello in Ecological Monographs! With a fantastic international team, we identify key challenges (“Raunkiæran shortfalls”) in trait-based ecology.

Dark diversity made its way to Nature!🥳🥳

Led by Meelis Pärtel (@MacroecologyUT), we show that dark diversity - species locally absent but suitable - can reveal hidden effects of human impact on plant biodiversity, opening new pathways for conservation.

Important new study in @nature.com on how #darkdiversity can give insights on the diversity in local #plant communities that observed #diversity can't. With contributions from me, my two @au.dk colleagues @tokehoye.bsky.social & Signe Normand and many others. www.nature.com/articles/s41...

New study in @nature.com: we focus on the diversity that's missing - “dark diversity.” Human impact means only 1 in 5 species persist in disturbed areas versus 1 in 3 in pristine ones. My summary of the project & its implications: the3dlab.org/2025/04/03/g...

#Biodiversity has many facets - some might be less apparent, such as the absence of species in locations that would normally be suitable for them. Important reminder that human activity impacts the biosphere in many ways!
Happy to have contributed to the 2nd northernmost dataset in this study :)

🌿 The first article of our DarkDivNet consortium, led by Meelis Pärtel, has been published in Nature. Our dataset from 5500 sites in 119 world regions, collected specially for this purpose, shows that plant diversity is negatively affected not only by direct human impact such as local disturbance.
