A cool way to look at size spectrum!
New study out! 🌐🧪
Human pressures are boosting invaders, cutting fishery value by over 50%.
A 21-year study led by Dieison Moi shows how invasions reshape ecosystems and threaten vital services.

Our study ‘The global human impact on biodiversity’ is out in Nature!

Through an unprecedented synthesis (2133 studies!) we show that humans are not only shrinking species numbers—but reshaping entire communities across the planet. 🌍🌐🐟🌿🪲

Can semi-aquatic insects track the quality of terrestrial subsidy ? We found that predators responded the most, followed by shredders. Dispersal traits did not respond at all. In brief, predators and shredders are transmission belts of cross-ecosystem perturbations (see 🧵for more). 🧪💧🌎

NEW PAPER, JUST OUT! 👀

Insects from the '70s and '80s were already collecting microplastic, decades before the term microplastic even existed. 🤯

A thread on the surprising history of this pollutant and the incredible insect larvae that helped us uncover it. 🐛

Estimating infection prevalence at landscape-scale can be tricky. In this study led by Juliane Vigneault we explored spatial scaling effects with sampling effort, we compared different sampling methods and their biases and we identified some key local drivers (a short 🧵👇). 🌎🧪💧

Salmon are an archetypal spatial subsidy transporting marine-derived nutrients and contaminants to inland freshwater and terrestrial food webs. When considering past and present ecosystems in Aotearoa, we should appreciate the role of diadromy in connecting multiple ecosystems #metaecosystems

This paper was a massive team effort that culminated in a simple story:
More biodiverse communities of invertebrates, in both terrestrial and aquatic ecosystems, have a higher content of "good fats" that are available for predators (e.g. bird, bats, fish, etc...).

In a new study, we develop a framework to identify nutrient hotspots in the landscape. We also discuss how nutrient spatial distribution can be indicative of underlying ecological processes. This could thus be useful to identify target habitats for conservation purpose (🧵👇) 🧪🌎 tinyurl.com/577jajvm

Nice to see so many people joining bluesky. I am not the most active, but I love finding about new research I might not have seen/heard about otherwise. As such, I will mainly use my account here to promote the work done by the students in my group and to sometime comments/share env. related news.

Out now @NatureEcoEvo: our review on how #invasive #species drive #cross-#ecosystem effects #worldwide.

Invasive species have globally profound impacts. These extend beyond ecosystem invaded, e.g. by altering flow of materials across the boundaries.

Reminder that work atmosphere and work location are also super important. I have the privilege to work in a place where I can grab my skis in my office and walk out the door...this has had tremendous impacts on my wellbeing, which I think are then reflected in my teaching and student supervision.

Hi all - this place seems great! I am planning to use this account mainly to advertise the nice work by students and ECR in the lab, share nice research from others, and comment on local and more regional environmental issues (in french and english). Looking forward to interact with you all !
