Ecological resilience is the ability of a system to resist or recover from perturbations

It’s a mystery to me why so many think the term suffers from a definition problem

and why we get more & more papers seeking to define it

Focussing on the carbon capture & storage potential of ecosystems

distorts conservation decisions towards those habitats thought to store more carbon than others

and perpetuates the idea that we can simply balance our emissions against (poorly quantified) sequestration in these ecosystems

18/ Fantastic synthesis by @matthiasschmelzer.bsky.social-

Scientists responsibilities are 3 fold.

1. Traditional role of responsible research, teaching & truth telling.

2. Activist-scholars acting alongside civil society to push for social change.

3. Defending the university & academic freedom

I often hear the argument that environmental scientists don’t understand how businesses financiers make decisions

What that really means is we can’t understand decisions that are made purely for short-term return on investment

rather than for maintaining a liveable future for people & nature

But the report has been delayed

Worrying numbers

Again, it’s not the actuality of rewilding, but how some talk about rewilding as some sort of magic solution that will work just by invoking it

But more importantly just waving the magic rewilding wand, and assuming all will be well, is dangerous

James Bullock @jmbecologist.bsky.social · 4d

I agree

But I’m concerned when people confuse the metaphor with reality

And believe that just by invoking ‘rewilding’ or ‘regenerative agriculture’ the job is done

James Bullock @jmbecologist.bsky.social · 4d

And that is a bad thing…

James Bullock @jmbecologist.bsky.social · 4d

Rewilding & regenerative agriculture can be subject to semi-mystical musings

about nature healing itself, or suchlike

The only way they will help achieve nature recovery is by taking a hard-nosed approach to evidence about what works, in what circumstances

James Bullock @jmbecologist.bsky.social · 5d

Reintroductions of species are often framed around ‘hope’ in the media

In reality they are often the last resort after other conservation approaches have failed

But it is easier to get attention for reintroductions of charismatic animals rather than boring old habitat conservation

Reintroductions can be sensible, especially under a rewilding ethos

But de-extinction is not!

James Bullock @jmbecologist.bsky.social · 7d

“It worries me that we humans prefer to be interested in shiny, high-tech projects as with the mammoth [‘de-extinction’]

People are running stats on LLM-generated participants and think they’re being social scientists when in fact they’re technically just playing a very strange video game. This is like saying you’re doing math research because you’re playing sudoku.

www.science.org/content/arti...

AI-generated ‘participants’ can lead social science experiments astray, study finds

Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings

That does relate to the idea of top down control, which is also debated. So those are the stories told, but it is rarely that simple - eg the Yellowstone wolves story

Yup

Technically that means they are ecosystem engineers

I’m saying that to illustrate the problem with such designations
