📰Ignasi Arranz Urgell, is co-author of the new article "Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities", published in @animalecology.bsky.social. 👀Read it here👇 doi.org/10.1111/1365... @ignasiarranz.bsky.social

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Our study shows that non-native species alter the relationship between the size-spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic nic...

📰Clara Sáez, Ignasi Arranz Urgell, Guillermo García Gómez and Javier Sánchez Hernández, IICG researchers, are authors of the new article "A simple index for assessing cumulative human impacts on mountain lakes", published in Limnology and Oceanography Methods. 👀Read it here👇 doi.org/10.1002/lom3...

A simple index for assessing cumulative human impacts on mountain lakes

Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we devel...

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/...

Increasing Functional or Phylogenetic Distance From Native Fish Communities Promotes Non‐Native Fish Invasions in Global Rivers

Freshwater fish invasions severely threaten ecosystems and their underlying drivers remain a subject of ongoing inquiry in ecology. Here, we leveraged a comprehensive database with taxonomic, functio...

📢 GLOSSAQUA is out in Ecology @esajournals.bsky.social. Big collaboration w/40+ coauthors led by myself, @chaevangelista.bsky.social & @ignasiarranz.bsky.social. It compiles global size spectra parameters from aquatic ecosystems globally👉: doi.org/10.1002/ecy.... #datapaper #aquaticecology 🌍🧪🧵(1/4)

Locations of aquatic studies included in the dataset (n = 135 studies) classified within eight biogeographic realms. The sizes of the circles are proportional to the number of studies per country in each biogeographic realm.

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

Juan Carvajal-Quintero@juancarvq.bsky.social · last yr.

PhD project alert! 🚨 I'm recruiting a PhD student to join my lab and the MacroSize network to investigate the trends, patterns, and processes driving intraspecific variation in fish body size in the Anthropocene. Exciting opportunity to explore ecological dynamics in a changing world! :) 🌎🐟🐠🐡

PhD Advertisement that reads: I am recruiting a PhD student to join MacroSize, a new international research network advancing hypotheses and theories on intraspecific body size variability in fish. The selected candidate will co-develop the project, analyze large datasets, and collaborate closely with MacroSize members, including co-leads Pablo Tedesco, Ignasi Arranz, Xingli Giam, and Juan Carvajal-Quintero. To apply, Send your CV and a motivation letter to juan.carvajal@dal.ca. Applications are open now and will be reviewed on a rolling basis. Start date September 2025 (flexible).
