Nuevo artículo con la participación del #biodiverso @ignasiarranz.bsky.social "Invasive Fishes Interact With Temperature to Reshape Community Size Structure Across Climatic Zones"

🐟 A raíz de la publicación del paper "Season and human footprint weaken the negative effect of temperature on the intraspecific metabolic scaling exponent of wild brown trout populations" de Ignasi Arranz Urgell (@ignasiarranz.bsky.social), investigador del IICG y @biodiversosurjc.bsky.social,... 👇

New paper out 🚀 masterfully led by Tao Xiang What drives fish invasions globally? We show that being different pays off: non-native species are more likely to establish when they are functionally or phylogenetically distinct from native ones. onlinelibrary.wiley.com/doi/10.1111/...

No hesitate to join this PhD position in aquatic ecology! A great environment, nice people, and great place overall!

A really amazing experience being part of this symposium organized by AquaSync on Synthesis Research!

🚨 Recruiting! I’m looking for two graduate students (MSc or PhD) already based in Canada to join my lab and work on biodiversity research - broadly defined. Based at Concordia University (Montreal) - competitive stipends will be offered. communityandquantitativeecology.weebly.com

El #biodiverso @ignasiarranz.bsky.social ha estado en Copenhage y he dado una charla explicando los diversos proyectos (MacroSize y SexSixe) en los que está trabajando. La charla ha sido en la real academia de ciencias y letras de Copenhage, un lugar espectacular.

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

Another publication also part of the Thematic Network on Biological Invasions (InvaNET) @ignasiarranz.bsky.social @biodiversosurjc.bsky.social @greco-udg.bsky.social @iea-udg.bsky.social @univgirona.bsky.social #InvaNET invasiber.org/InvaNET/2025... doi.org/10.1002/ece3...

New global data ready for assessing macroecological body size patterns across ecosystems! With @zzeynepersoy.bsky.social and @chaevangelista.bsky.social leading this effort plus 40 more researchers! Funded by @sibecol.bsky.social

🗣️Varios medios de comunicación han cubierto el artículo de @ignasiarranz.bsky.social  que pone de manifiesto la importancia de factores macroeconómicos, como el Producto Interior Bruto, en las invasiones biológicas. 👀Léelo👇

📖Adrián Escudero, director del IICG, acaba de publicar un nuevo libro en @tundraediciones.bsky.social "Biodiversidad. Entre la urgencia por frenar su pérdida y su complejidad". ⚠️Puedes pedirlo ya en preventa👇

New paper out assessing trophic ecology between native vs non-native species in two Iberian lakes! Great work lead by Javi and other amazing coauthors!

👀 Have a look at this new exciting PhD opportunity! Dive into macroecology, body size, and biodiversity while collaborating with an international research network!

New paper out in @ecol-evol.bsky.social ! We assess the variable importance of several ecological, economic and population drivers in shaping the global distribution of alien-species introductions across multiple taxa. Great collaboration with @garciaberthou.bsky.social and Ralph!

Enhorabuena #biodiversos por el artículo liderado por J.Sánchez-Hernández "Variations of plerocercoid infection rates in fish communities across Spanish mountain lakes" en Aquatic Ecology @guillegargomez.bsky.social @ignasiarranz.bsky.social @iicg-urjc.bsky.social link.springer.com/article/10.1...

💡Un poco de inspiración para fomentar los espacios de brainstorming No te pierdas la infografía que realizó @jmalumbresolarte.bsky.social en nuestro primer Workshop de la convocatoria Forward Thinking, #MACROsize

Look at one of the amazing outcomes from the last workshop organized at the @iicg-urjc.bsky.social made by the brilliantly scientific illustrator @jmalumbresolarte.bsky.social! It summarizes key aspects in how to foster workshops, framing a space for brainstorming, and planning future strategies

I'm hiring, two fully funded PhD positions! Come work in Umeå in Arctic Sweden, a leading place for high-latitude ecosystem ecology and carbon biogeochemistry

📢 Please repost: Two @treesdla.bsky.social PhD positions in #tropical #ecology going with me and Dan Perkins (+V Saito & @gqromero.bsky.social ): Pollution across aquatic-terrestrial realms: bit.ly/4g9wXow Land use change & river food webs: bit.ly/4fcisPH Get in contact, deadline Jan. 20th.

Newbie here and curious to see how it works—taking a break from the other! Postdoctoral researcher at IICG and URJC, exploring biodiversity and ecosystem functioning in freshwater habitats. Interested in body size scaling, biological invasions, macroecology, food webs and more!
