This meta-analysis finds that planting nitrogen-fixing species increases soil carbon compared with non-nitrogen-fixing species, potentially offering a nature-based solution to mitigate climate change for forestation, agriculture and land regeneration 🧪🌳

Impact of emerging compound droughts on forests: A water supply and demand perspective This review examines the physiological and ecological responses of trees to emerging compound droughts from a water demand and supply perspective, as well as the role of acclimation and consequences ...

🌳🔥Out now: Our review on compound droughts and forest responses - from leaf to ecosystem. Featuring a stunning 20-yr map of canopy temperatures variation across European forests. @chriswernerlab.bsky.social @simonhaber.bsky.social @vallicrosah.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

Pantropical tree rings show small effects of drought on stem growth Increasing drought pressure under anthropogenic climate change may jeopardize the potential of tropical forests to capture carbon in woody biomass and act as a long-term carbon dioxide sink. To evalua...

Yes, many tropical trees have annual rings! Great to contribute to this global synthesis led by @pieterzuidema.bsky.social, indicating stronger droughts w climate change may shift observed more resilient responses toward more widespread decreases in productivity www.science.org/doi/10.1126/... 🧪🌾🌐

Limited carbon sequestration potential from global ecosystem restoration - Nature Geoscience The maximum carbon sequestration potential from global terrestrial ecosystem restoration efforts until 2100 is 96.9 Gt, which is equivalent to 3.7–12.0% of anthropogenic emissions until then, accordin...

This paper is getting attention for suggesting ecosystem restoration won't help with mitigation, but restoration is still *critical* for adaptation.

Restoring coastal wetlands helps reduce risks from sea level rise and hurricanes, restoring urban forests helps reduce risks from extreme heat, etc...

A very comprehensive analysis of lagged precipitation effects in terrestrial ecosystems. Tree rings, flux, grassland ANPP, satellite remote sensing, and DGVMs. Climate memory is an important driver of global plant productivity.

"if we plan restoration targets to match future climatic conditions and consider state transitions of currently natural ecosystems due to climate change, the potential for natural climate solutions related to ecosystem restoration is close to zero." www.nature.com/articles/s41...

Also in GCB: a meta-analysis of precipitation pulse-responses in C and water cycling (doi.org/10.1111/gcb....). *Huge* effort by @ecophysism.bsky.social. We characterized both the size of response to pulses, and also the shape (do we even see a hump?). Future C-water coupling shifts are possible 🌐🌍

Cool results from the #funpotential project presented by @mikkopel.bsky.social today at the biodivclim final event @biodiversa.eu.
They help understand how and why tree diversity can help to adapt forest to climate change.

The objective of the scanners developed by the team “Emma Belaud, Christophe Jourdan, Mickael Hedde and Philippe Gallet ” is monitoring root dynamics and soil macrofauna.

The “Brazil team” Agnès Robin, Daniel Poultney, Joannès Guillemot and Guerric Le Maire @umr-ecosols.bsky.social @cirad.bsky.social installed buried scanners (paper link below) in the MataDIV Experiment (TreeDivNet) with the teams from Floragro and the Itatinga experimental station (ESALQ-USP).

Natural disturbances are often invoked as an argument against creating new forest reserves. But are reserves more affected by disturbances than managed forests? For C Europe the answer is no, in fact reserves have lower disturbance rate & severity than managed forests! doi.org/10.1111/1365...

This French company has designed an e-bike that doesn’t need a battery The brainchild of French entrepreneur Adrien Lelièvre, the Pi-Pop e-bike uses a supercapacitor to store energy rather than rely on batteries.

French designed bicycle that uses supercapacitors instead of batteries to power the bike, only paper, aluminium and carbon used in the capacitor so it's easy to recycle.

Pretty neat

Habitat connectivity is important for bats too! Many bat species like to fly along forest edges, inside forests or just near some kind of safe cover. Open expanses can fragment habitat for these species. #AirspaceIsBatSpace

Species turnover does not rescue biodiversity in fragmented landscapes - Nature An analysis of habitat fragmentation using a dataset of more than 4,000 species worldwide shows that fragmentation reduces biodiversity at all scales, and that increases in β diversity do not compensa...

“Fragmented landscapes consistently have both lower α diversity and lower γ diversity [but higher β diversity]

Our findings refute claims that habitat fragmentation can increase biodiversity at landscape scales”
