📢 Funded PhD opportunities for UK candidates in beautiful Edinburgh. Get in touch if you're interested in a PhD on understanding the mechanisms of soil carbon cycling and the role of microbes. We work in different ecosystems: peatlands, forests and agricultural soils. Please repost/spread the word.

New paper in diamond open-access @peercomjournal.bsky.social Reducing mineral fertilizer use in mountain grasslands could improve the ability of their soil to maintain their multifunctionality during drought.

Hi there, my student is making a survey about the use of R packages in Ecology, could you please spend two mins on filling it 🥹 Very appreciated! And if you could spread it further (RT), that would be just awesome. ❤️ docs.google.com/forms/d/e/1F...

docs.google.comExploring R Package Usage in AcademiaI am running a quick survey to find out which R packages academics use the most in their research and teaching. The goal is to see which tools are essential, spot any gaps, and maybe even discover som...

This gorgeous creature is the prickly stick insect (Acanthoxyla prasina), one of New Zealand's 23 species of stick insect. Huge thanks to @morganemerien.bsky.social for pointing this out on a recent University of Canterbury field trip - it's great fun teaching entomology! #Invertebrate 🧪

Dear colleagues, If you use "Greetings of the day!", "distinguished speaker", or "your valuable submission" in your emails, my new bespoke spam filter will mark is as read and delete it. Works like a charm for now. I eagerly await for your valuable spam-filtering term suggestions. 🙏⤵️

Introducing New Zealand's latest Bug of the Year- the magnificent Ngāokeoke / Velvet Worm! NZ has two genera: one lays eggs (Ooperipatellus, 1st photo) and another gives live birth (Peripatoides, 2nd). They also deposit sperm which burrow through their partner's skin, but that's another story! 🧪

Notre unité a mis au point des scanners enterrés pour étudier la dynamique racinaire puis plus largement les interactions biologiques dans le sol. La chaine "écran de savoir" des universités de l’Occitanie-Est, présente en vidéo cette innovation technologique : www.youtube.com/watch?v=GgDe...

We're all on tenterhooks waiting for the results to be announced tomorrow for the NZ Bug of the Year competition! Here's a few of my favourite contenders. Now voting is over I'll admit I have been quietly rooting for the velvet worm too - they're amazing animals! Good luck #TeamGiantSpringtail!

Hello, Bluesky! ☀️ We fund frontier research in Europe—bold ideas, unexpected discoveries and science that shapes the future. So it’s only fitting we’ve landed here. Sorry for being late. Follow us for updates on ERC funding, research policy, and our grantees' discoveries.

Tough but essential debate for our labs. Aude Valade from our unit and Tamara Ben Ari, call for a convention on the environmental ethics of research: How do we decide what research to continue? What criteria to evaluate energy-consuming research? How can we distribute reductions? Paper in French 🇫🇷

Eco&Sols has now moved to bluesky! Our research unit works on functional ecology and biogeochemistry in agroecosystems, from the biodiversity in soil aggregates, to plant-soil interactions and global C cycle. This account will share publications, project updates, job opportunities and more.

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 👇

What a great demonstration of the importance of permanent grasslands for soil carbon sequestration!

François-Xavier Joly@fxjoly.bsky.social

Using four regional chronosequences, we found that converting permanent grasslands to Scots pine forests significantly reduces soil carbon stocks: in ca. 60 years, the bulk soil C stocks in the organic layer and the top 20 cm of mineral soil decrease by half compared to unforested grasslands.

These findings highlight the need to consider soil carbon stock changes in tree-planting projects to accurately assess their carbon sequestration potential. Simply accumulating biomass in vegetation does not guarantee a net carbon gain for the ecosystem.

Using four regional chronosequences, we found that converting permanent grasslands to Scots pine forests significantly reduces soil carbon stocks: in ca. 60 years, the bulk soil C stocks in the organic layer and the top 20 cm of mineral soil decrease by half compared to unforested grasslands.

The net carbon sink of 60-year-old pine forests was reduced by 1/3 compared to estimates based on tree biomass alone. Notably, this soil carbon loss was primarily driven by a reduction in mineral-associated organic matter, a fraction considered relatively stable.

Tree planting is presented as a nature-based solution to mitigate climate change as trees store carbon in their biomass. But most terrestrial carbon lies in the soil, so soil carbon changes must be taken into account to determine the direction and magnitude of changes in ecosystem carbon stocks.

No later than last week, colleagues and I were asking how effectively do some "biodegradable" materials actually degrade. Useful answers, albeit not what we'd hope.

François-Xavier Joly@fxjoly.bsky.social

🚨Biodegradable waste does not always degrade faster than plastic🚨 Here, we compared the degradation rates of 7 single-use items made of biodegradable material or plastic, on land and at sea. In most cases, there was no difference between plastic and biodegradable material... ⬇️ tinyurl.com/mrye9x8s

Slime molds may resemble fungi, but are in fact a distinct group of unrelated organisms. Although they're single-celled organisms, they'll also perform an astonishing feat of cooperation - gathering together as a collective ‘organism’ to form amazing fruiting bodies. Which is your favourite? 🧪🍄
