thank you to all my co-authors for this nice paper, mostly birthed during a workshop in 2023 with even more colleagues. It is so nice to see published the result of many brainstorming and various working sessions!
It was very stimulating work during, and after.
Thank you all!

We propose a simple, standardised measure to quantify and communicate the magnitude of biological invasions: total biomass of non-native species. This metric approximates the amount of native biomass co-opted, displaced, consumed, or replaced by the populations of invasive species.

How do we know the extend of biological invasions?
Is it a large invasions? A small one?
How do we compare invasions of tiny organisms (e.g., ants) and of larger ones (e.g., rabbits)?
How do we quantify objectives, or efficiency of management?

Derrière les invasions biologiques, un remodelage silencieux des écosystèmes Les invasions biologiques ne touchent pas seulement les espèces, mais également les sols et les écosystèmes au sens large. Un nouvel outil propose de mieux prendre en compte ces impacts.

How biological invasions are silently remodelling ecosystems:

our paper in @plosbiology.org about the extension of the #EICAT impact classification of biological invasions has now an outreach piece!

Read the (shorter and easier) version of the story here:

EEICAT will allow more complete and precise impact assessments, especially for species that affect communities, habitats, ecosystem functions and abiotic conditions. These include ecosystem engineers such as many invasive plants, bivalves or ants, for example.

It keeps the 5 (Minimal to Massive) severity categories, only adding three ecological levels (individual-population, species-assemblage, ecosystem-abiotic).
All assessments previously made with EICAT thus remain valid, but can be updated to incorporate hitherto missed impact types.

It also focuses on the invasion rather than on the invasive species, meaning that each invasion species can be attributed several impact severities within an invasion, or globally. This allows a more complete invasion description, and accounts for variability across invasions.

It now takes into account all 19 types of ecological impacts (vs. less than half previously), including those at the species assemblage, trophic web, ecosystem and abiotic levels (including soil composition, water quality, microclimate, fire regimes, etc).

Expanding invasive species impact assessments to the ecosystem level with EEICAT This Consensus View introduces EEICAT, a framework for assessing how biological invasions affect species, ecosystems, and the environment. It covers 19 types of impacts and aims to help scientists and...

In our new @plosbiology.org study, we introduce #EEICAT, an evolution of the #EICAT framework to include communities, ecosystems and abiotic habitat components into biological invasions impact assessments.

thank you Shengyu for helping make this mission smooth and enjoyable. Thank you also for contributing to the success of #InvaPact IV in Beijing!

Thank you to the AXA Research Fund for supporting #InvaCost. Thank you to @cnrsecologie.bsky.social for supporting my salary and giving me total research freedom, to @univparissaclay.bsky.social for hosting me, and to my colleagues at ESE & @ideevl.bsky.social for making this job so enjoyable 🤗

Of note, this exceptional #InvaPact program, on which over 140 colleagues now contribute from 33 countries, was started 3 years ago, and I still have found no source of research funding for it... If you are a sponsor or a rich philanthropist... 😉

This is mostly the work of the #InvaCost program (invacost.fr), which yielded 79 published studies.
We have now the new project #InvaPact coming up, which will be even better and more impactful.

Such ranking is rather meaningless in science, but it is nonetheless a recognition for dedicated, hard and creative work, not only by myself, but by my entire team, among whom those who were my postdocs at the time: Christophe Diagne, @bleroyecology.bsky.social, ElenaAngulo and AnnaTurbelin.

Highly Ranked Scholar Award

As we approach the happy times of end of the year, I couldn't resist sharing the award I received this morning: first scholar in the world in the field of Sciences of Invasions. For the second year.

InvaPact III workshop is now over: WHAT A WEEK! ~60 experts from 30 countries putting their brainpower together for an unique collaborative project.
Work hard, play hard: they really followed my motto!
Powerful publications on the way!

Thank you to the sponsors of this fifth workshop: @AXAResearchFund, @ofbiodiversite.bsky.social @cnrs.fr @FondationLuciole

Today we start the InvaPact III Workshop in Barcelona Spain! 60 experts from 30 countries to work 6 days on the standardisation of ecological impacts of #BiologicalInvasions.
This (largely) new crew is fantastic, this is going to be amazing!
Please give your BlueSky handle if you're part of it!

Just received my fresh copy of @franckcourchamp.bsky.social's new biodiversité comic! Only in French, but other languages, including English, coming out soon.

When plants or animals move, or are moved, to a place they don't belong, there is a risk of damage to natural habitats and an economic cost too.
@franckcourchamp.bsky.social talks to @talknormal.co.uk about how we estimate the size of this risk and what we can do about it

Workshop format

Focused data analysis sessions in small groups
Mix of plenary sessions & independent/group work
Strong spirit of collaboration, mentoring & knowledge sharing
