Toxic metals may be spreading through wildfire smoke as Canadian peatlands burn A thick cloud of smoke from hundreds of wildfires in Canada is carrying more than just carbon, as scientists warn that arsenic, lead, and other toxic metals trapped in soil could be released into the ...

Our toxic dystopian world @1.5C

“It’s a bad-news scenario. It’s quite scary.”

Decades of mining have left northern Canadian soils contaminated with metals like arsenic and lead, which are now being released as wildfires burn through peatlands and old industrial zones

Coring lakes in Šumava forests in Czech Republic to study ecological processes linked with bark beetle outbreaks.
Thanks @damienrius.bsky.social and @petrkunes.bsky.social for this very nice and interesting fieldwork!
Can't wait to see what we'll discover 🧐🌲🪳😲🤩

Returning to Šumava's lakes to study recent <200 years bark beetle disturbances with @damienrius.bsky.social and @cecileremy.bsky.social 🌲🪲

Coring lakes un the Sumava mountains, Czech Republic, with @petrkunes.bsky.social and @cecileremy.bsky.social, to track past bark beetles outbreaks!

Hi #sedaDNA community! We are looking for a postdoc to join our team @chrono-env.bsky.social in developing qPCR and ddPCR methods to reconstruct past insect outbreaks. This 2 yr position will be part of a larger @agencerecherche.bsky.social project that
that integrates paleoecology, sedaDNA and

voila où mènent les ZRR. Chers collègues de

, il faut vraiment continuer à refuser ça !

High-intensity wildfires increase with timber plantations in many temperate countries (orange), and will only continue to grow if the climate keeps warming

d'une hypocrisie insupportable quand on vit au quotidien ce qu'est la réalité de la recherche française. In other words for US colleagues : the level of bullshit here is through the roof!

Chironomid assemblages in surface sediments from 182 lakes across New England and Eastern Canada: Development and validation of a new summer temperature transfer function

Congrats to T. Suranyi for his excellent first paper ! this is going to advance our understanding of climate change, both past, present and future, but it's also crucial for a lot of projects in disturbance ecology, coupling paleo & modeling ! @chrono-env.bsky.social @cnrsecologie.bsky.social

Ravi de t'accueillir !

Coring by -15/-20°C is quite challenging, but the scenery is amazing!

Today we cored the first lake for the RETROPEST ANR project in the Pipmuakan area, west of Manicouagan, Québec, in collaboration with the Canadian Forest Service and Conseil des Innus de Pessamit! @cnrsecologie.bsky.social @chrono-env.bsky.social @chrono-env.bsky.social

French research system: go big, go international. French administration: hold my beer. If you want to fund international partners for fieldwork they'll have to fill in 472 forms and provide 876 documents that only exists...in France. Then we'll reimburse your international partners. Well, maybe...

We are dedicated to supporting the wildland fire community and making it clear that the global fire crisis will not be solved by lack of funding, resources, or people. Read AFE’s statement on recent US federal actions here: fireecology.org/news/afe-sta...

Paleorecords Reveal Biological Mechanisms Crucial for Reliable Species Range Shift Projections Amid Rapid Climate Change Climate change has created an urgent need for reliable projections of species distributions. By hindcasting forest tree range shifts across Europe over the last 12,000 years, we show that process-exp...

Interesting work by van der Meersch et al. out in Ecology Letters, nicely illustrating that process-based models are more robust than correlative models for predicting species distributions under novel climatic conditions doi.org/10.1111/ele....

la recette miracle de l'ESR : réunir toutes les conditions pour que les agents fassent des burn-out et ensuite dégrader leur indemnisation en cas d'arrêt-maladie. Du grand art.

On peut également ajouter que dans la première liste qui a fuité, l'Institut Écologie et Environnement du CNRS était celui avec le moins de keylabs, en proportion, par rapport aux autres instituts (18% vs 25% au global). Un peu désastreux comme message...

New paper! Forest disturbance through drought, windthrow, pest outbreaks and fire is increasing in Europe, driven by past planting decisions and climate change. In Germany alone, more than 500,000 ha of mostly Spruce died back in 2018-2022. Led by Anne Graser, we studied biodiversity responses...

Hi Graciela, i'd like to be added!

My bad, it was more ca 2400-2500m. Still crazy for January

Their majesties Dent Blanche & Matterhorn, yesterday. Better enjoy the mountains in winter before there is no winter left: isotherm 0° was >3000m today🤯
