🙀Invasive species cause such diverse ecological impacts that we needed to broaden the lens used to classify their effects. Very happy with the collaborative and progressive nature of this work, integrating previous efforts and helping fill key gaps after years of worldwide effort!

Hey hey this is free and open to all - come make plans with us!

Lovely to meet the team at Stirling and get a sneaky look around their awesome aquaculture centre last week.

Note to self to stop dressing like I’m about to rob the gaff 🌚

"Leadbitter et al. 2025 calculates that replacing wild-caught seafood protein with the current mix of livestock protein would cost the Earth roughly 5 million km2 in land, about the size of the Amazon rainforest, an apt comparison since most land cleared for food comes from tropical forests." 🌏🐟

Dimensions of Tamazirt thinking

Many Indigenous philosophies acknowledge respect & reciprocity between people & nature. Affective ties to land & home are also at the heart of Tamazirt thinking of Amazigh communities in Morocco. Tamazirt could serve as an Indigenous anchor point for rural revitalisation.

For the first time ever I’ve had someone (a senior co-author in fact) complain about the inclusion of an acknowledgment statement recognising the indigenous displaced people of the region we focus on in our manuscript.

Poor form & baffling behaviour/reasoning from someone who should be better.

No Free Lunch: Sustainable Aquaculture Requires Recognizing Past Science, Improvements, and Comparative Assessment Aquaculture has become an established and important part of the global food system. Several critiques of aquaculture continue to resurface, seemingly ignoring past research and improvements of (1) aq....

A recent Science Advances special issue focused on #aquaculture, but seemed to have missed the mark in a multitude of ways. My incredible colleagues and I wrote this sweeping Open Access opinion article (with 80 citations!) in response. Hope it's useful! 🐟 🦐 🎣 doi.org/10.1111/raq....

Google Scholar tool gives extra credit to first and last authors Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.

New rules for a rat-race. I my opinion, all this micro-accounting (= internal author struggles), inhibits effective collaboration. Science increasingly turns to a goal-oriented bureaucracy, away from an open art-like exploration, curiosity and thruth-seeking.

& we ran a workshop on how to upscale conclusions in invasion science with a team of biomechanics, network ecologists, engineers & invasion scientists

This week was full of training, workshops and seminars. @leopoldadrianus.bsky.social taught the group ecomorphology, @ecoinvasions.bsky.social gave an insightful lecture on context dependent invasion impacts

@leopoldadrianus.bsky.social teaching @universityofleeds.bsky.social post grads the ins and outs of fish eco morphology

Indonesians fight to save peat land from being converted for agriculture Indonesia has more tropical peatland than any other country, but it is also quickly losing this poorly understood ecosystem.

Indonesia's peatlands are home to endangered orangutans, as well as economically important fish species. They also help prevent flooding and drought, lower local temperatures and minimise saltwater intrusion.

New OA paper: www.sciencedirect.com/science/arti...

An isolated stream pool above a culvert (not visible, where the photographer is standing) with a dry bed upstream. The pool is turbid and surrounded by dry steppe, with mountains visible in the distance under a mostly sunny sky.

Our search for invasive crayfish barriers includes more than just dams or irrigation diversions. Because the virile crayfish is intolerant of stream drying (doi.org/10.1086/725318), intermittent reaches could present barriers to upstream spread to permanent streams in the mountains.

Furthermore - we are a close knit community of friends & colleagues- where disagreement & critique are key to developing ideas. We continue to work together in a positive manner.

Misrepresenting our response as villainising is - as you say - a lack of fidelity to the original works

Villainising was never the premise of our response, rather a commentary from the invasion science and global migration network regarding shallow analyses & sensitive commentary - you can mean well but represent yourselves in a way that disadvantages both disciplines & maligns your points

My problem with the original paper is its reckless application of invasion concepts to human migration. That would've been fine had it unambiguously showed how scientifically inappropriate such comparisons were, rather than offer weak critiques & claim that insights were to be gained from them.
