Tropical forests are not all the same: they show many shades of geographical variation. Our new paper in Nature led by @jeaggu.bsky.social combines field and satellite data to make a first map the canopy functional traits of the world’s tropical forests: www.nature.com/articles/s41...

Canopy functional trait variation across Earth’s tropical forests - Nature

Data from a variety of sources—including satellite, climate and soil data, as well as field-collected information on plant traits—are pooled and analysed to map the functional diversity of tropical fo...

How are disturbances shaped across the world’s #forests and how are humans influencing these patterns? We built a global map of forest disturbance structures to explore these questions. Check out my first paper in Nature Sustainability @natureportfolio.bsky.social www.nature.com/articles/s41...

Landscape patterns in stand-replacing disturbances across the world’s forests - Nature Sustainability

Forests are subject to natural and human-induced disturbances, which can be important in shaping their form and function. In this study, the authors examine the landscape patterns of global forest dis...

Are you a scientist that analyses/creates models using data from cameras, acoustics, drones or satellites to understand biodiversity? Join the Biodiversity Monitoring starter pack. Point me to your research to be added. ECRs and PhDs welcome! 🧪🌏 #AI #conservation go.bsky.app/eFMQQX

📢 18-month postdoc in my lab doing drought modelling with either the UK land surface model JULES or machine learning. Up to you which. Please share widely (thanks) www.bristol.ac.uk/jobs/find/de... Closes: 18th January

We had a great morning at #AGU24 today with lots of exciting stable isotopes studies investigating the Critical Zone. People showed interesting water, carbon and nitrate isotope application in various environments. Fortunately, we allocated sufficient time for discussion which was well received. 👇

I am excited to announce that we are organising again the #treering session at #EGU25. 🌲💍Abstract submission is now open until Jan 15. tinyurl.com/sbdt4ezp KerstinTreydte Jernej Jevšenak Annemarie Eckes-Shephard and Pieter Zuidema #dendrochronology

Nice mix of fieldwork in Finland & pollen and nectar chemistry 🐝🌼🌳🌲 🧪🌍 Apply by 20 Jan www.trees-dla.ac.uk/projects/eff...

I've made a starter pack of those with interests in tree-ring science e.g. dendroclimatology, dendrochronology, dendroecology. Please let me know if you'd like to be added (or removed!) or to suggest others to add go.bsky.app/LXrT3xb

🌎🧪Forest Ecology Starter Pack now available for those studying various aspects of forest 🌲🌳🌴ecosystems. The starter pack is limited to 150 names & it is now full. To grow your network: follow folks, get followed, re-post, & enjoy! go.bsky.app/8ZNK9jy

I know we have a million starter packs right now, but I think we need one for forest management & policy! I know I missed a ton of people, so if you'd like to be added, please message me (particularly you tropical foresters). Or, if you don't want to be on this list, lmk!

First things first!! Our simple but efficient method for the simultaneous determination of #carbon, #oxygen, #hydrogen in a sample, e.g. #cellulose, #sugar and organic material, is now published in Rapid Communications in #Mass #Spectrometry: doi.org/10.1002/rcm..... Happy reading and measuring!
