What do SIBECOLogist do? New research led by researchers at IEO-CSIC shows that southern bluefin tuna 🐟 larvae are growing faster than 30 years ago 📈 but warming 🌡️ oceans may push them close to their thermal limits.

Dissolved organic matter released by phytoplankton (i.e., acidic polysaccharides) or of terrestrial origin (humic and fulvic acids) can coagulate to form particles by the intervention of cations such as calcium and iron. These particles can be stored for a long time in the sediments affecting the global carbon cycle or be directly consumed by protozoa and zooplankton, forming the particulate loop.
Happy to share our new paper:"Calcium and iron promote reversible self-assembly of dissolved organic matter into particles" Open access: lnkd.in/dpQZHcRS
We dedicated this paper to the memory of our mentor, colleague, and friend, Jonathan Cole, who always had time to listen and inspire us.
Love these numbers. This issue worries me since many years
just out of the press…maybe the last single author publication in my career….

¡NON STOP estes días no #SIBECOLAEET2025! 🙌
Pósters, workshops e charlas sobre os nosos proxectos e traballo no #GOB.
Parabéns aos organizadores e grazas a todas as persoas que compartiron experiencias e coñecemento connosco 😃

Un gran grupo de #biodiversos han estado esta semana en Pontevedra en #SIBECOL2025 Especial mención a Adrián Escudero por su premio Luis Balaguer, a Silvia Matesanz por impartir una de las plenarias y a Ester Hernández por su premio al mejor póster @sibecol-aeet-25.bsky.social @sibecol.bsky.social
At the SIBECOL conference, besides meeting old and new colleagues and learning a lot, my friend @ylndmc.bsky.social and I won a best poster award for our study on trait distributions - thanks to the organisers for such a nice conference!!

💚✨ Thank you.
After an intense, inspiring and unforgettable week, the III SIBECOL & XVII AEET Meeting comes to an end — and yes, we’re already feeling nostalgic.
Very interesting finding: photochemical formation of N2O in freshwater and marine waters.
The N cycle gets more complex. 🧐

Exciting! And likely occurring in soils as well to help explain the rapid reduction of 15N-nitrate to N2O we observe in sunny California deserts. www.science.org/doi/10.1126/...
All hail the resilient rotifer! All-female and able to survive 24,000 years on ice - the bdelloid rotifer in the running for The Guardian's 2025 invertebrate of the year!

Some bacteria and archaea make nitrous oxide during ammonia oxidation to nitrite in well-oxygenated waters, whereas denitrifying bacteria produce it during reduction of nitrate in oxygen-poor waters. None of these, however, could fully explain the observed increase. ‘It was just this weird conundrum that in many cases the mechanism that was being used to explain most of these emissions didn’t seem to be there,’ says Jennifer Glass at the Georgia Institute of Technology in Atlanta, US.
![Scott Wankel of Woods Hole Oceanographic Institute in Massachusetts believes that the ‘exciting’ findings could solve a key mystery: ‘For a long time we’ve known that whatever nitrous oxide was getting out into the atmosphere was made in the upper [ocean] layer, and we thought that was nitrification by ammonia-oxidising bacteria and archaea – but they don’t like light,’ he says. ‘Here all you need is for the upper metre of seawater to have some organic matter in it, and the nitrous oxide will be quickly released to the atmosphere … it really could be driving the entire bus of the oceanic flux of nitrous oxide to the atmosphere, or at least a very large part of it.’](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:j3jocydwe4cpivirfuw47mhg/bafkreic2dwimpjer575f5snd4mv5bhdrqs2j7vp7hz6ovjhoevt3kd7lqe)

I am truly amazed by the reception our discovery has received in the scientific community 🥰🥰🥰

La microbiota de los mosquitos juega un papel clave en su biología y capacidad de transmisión de patógenos.

Interestingly, the CO2 respired from incubations of these same soils was closest in age to the most labile ramped oxidation fraction - indicating that the respired CO2 was from a thermally labile organic carbon pool.
