Yet another study finds that diverse forests store far more carbon than monoculture plantations. Previous research in the tropics showed it could be 40x more. Natural forests also help stabilise the climate in other, equally vital ways. WHEN will this penny drop? scienceblog.com/tree-diversi...

A century of rising CO₂ has increased photosynthesis of mature trees in tropical forests. This is our conclusion in study led by Sophie Zwartsenberg in @newphyt.bsky.social. We did novel isotope analyses in tree rings from Australia, Thailand & Bangladesh. nph.onlinelibrary.wiley.com/doi/full/10....

🌳New study exploring the importance of tree diversity for C cycling and climate change mitigation in tropical forests. From a great team, brilliantly led by @mixedforests.bsky.social. Results are nicely discussed in the press release: uni-freiburg.de/en/tree-dive...

A new study from Colorado State University reveals that tree ranges in the interior US West are contracting due to climate change, with limited expansion into cooler, wetter areas. The study highlights the potential need for human-assisted tree migration. phys.org/news/2025-02...

Hi bluesky! I will only share news on my research here. My main topics are microbial ecology and biogeochemistry. My current research digs into the functioning of root-soil system in deep horizons of agroforestry systems and the global life history strategies of soil bacteria. Recent publications 👇

Our new @pnas.org paper shows a previously unrecognized mechanism by which climate warming reduces beech growth: more frequent seed production depletes tree resources, causing a 28% decline in radial growth. www.pnas.org/doi/10.1073/... Funded by @ncngovpl.bsky.social

How does variation in ectomycorrhizal fungal diversity affect tree growth? What are the knowledge gaps to more fully answering this question? See my review out today in Fungal Ecology: doi.org/10.1016/j.fu...

Have a species list and want to get a phylogeny for them? Try this R package: nsojournals.onlinelibrary.wiley.com/doi/10.1111/... Feedbacks are welcome.

Previous research showed tree growth to be temporally decoupled from GPP, but what about biomass? Here we find that the fraction of GPP allocated each year to woody biomass widely varies across sites and years, notably as a function of climate. Shout out to Steve Kannenberg for leading this work!

We are reading this paper - again! - for lab meeting this week. It’s so good and essential that it requires periodic revisiting, esp. as new folks join my group. Generates great discussion and introspection. The authors also approach the topic with refreshing humility. doi.org/10.1002/ecy....

There is an idea that we can simply step away from degraded ecosystems & they will recover But truly biodiverse, resilient ecosystems are complex So, in degraded landscapes, we will often need to intervene to guide systems towards complexity besjournals.onlinelibrary.wiley.com/doi/10.1111/...

To my dear Ecologists: do you know about the Vendi Scores? They are a family of diversity metrics that account for species similarity. They are simple to compute. We provide code for computing them in both Python & R. #EvoSky Python: github.com/vertaix/Vend... R package: github.com/vertaix/Vend...

The earth gets drier and warmer, and #megadroughts have been increasing for 40 years and will do so in the future. Substantial negative impacts on #water supply, #agriculture and all #ecosystem services are to be expected. www.science.org/doi/10.1126/...

New paper in @science.org ! Where and when did the #multiyear-droughts occur around the world? Have they become more prevailing? We identified over 10,000 such events and found that they have been increasingly occupying the terrestrial land. (1/6) www.science.org/doi/10.1126/science.ado4245
