I embarrassingly let a super minor revision that I had no intention of sending back to reviewers sit with me for 3 months until the EiC contacted me personally after getting notified by the authors. I searched my email. Zero notifications in my inbox including spam.

So I think it is Wiley's new system. I'm an editor at 2 journals a big one that uses the old system and a small one that is forced to be one of the many guinea pigs over the next few years. Definitely some pluses to the new system software but overall it is a big miss.

Matthew Holden 🏳️‍🌈 @matthholden.bsky.social · 05/03/2026

At some point the EiC needs to take over as editor or reassign an editor to make a decision. We get that sometimes editors become unavailable but that is why the EiC exists, and usually is paid (even if quite little). Also Wiley's new system sucks. Doesn't even send editors reminder emails.

This isn’t just strategic, it’s responsible science: • Full model first ⇒ scrutiny & feedback • Applied results later + confidence it’s right • Two citable papers • Science people actually read Full models belong in modelling journals (bonus points for society journals like NRM)

For those who have never had Ethiopian. It's amazing. Lots of stews, eaten with a fermented flat bread called enjira. It's like a sourdough pancake made from a mix of teff & wheat flour. This place has a mild one that isn't as sour as the Eritrean version I'm more familiar with from back home.

It's baffling why the Go8 (a group of 8 leading universities in Australia) endorsed a position to weaken environmental laws. Not only do we, the researchers at these universities, disagree, but our research shows it is a bad idea. In just one day, 90 Go8 researchers documented our opposition.

This is excellent. I once reviewed a grant in a European scheme that had 12 while men on the team. I used similar framing to critique the issues, even though EDI was not included in the criteria. I also followed up with the scheme to ask why no EDI.

the answer to the trolley problem is not to pick who to sacrifice, it’s to dismantle the system that led to an unsafe trolley crossing. if any part of your morality strategy involves picking a group to let die on a hill, throw the entire strategy out. it’s wrong.

Yes, where nuclear plants exist they should continue and be maximised to produce relatively clean energy. Of course, in Australia, and other sunny locations building new nuclear plants is extremely costly compared to solar, even accounting for storage and would be wildly irresponsible.

010

Matthew Holden 🏳️‍🌈 @matthholden.bsky.social · 16/06/2025

The latter (sorry character limits created the ambiguity). Agree with you, given that accounting for species protection only adds 2-3%cost, it would be interesting to see what the cost contribution of the renewables are alone. Would help to put that 2-3% in context.

010

Matthew Holden 🏳️‍🌈 @matthholden.bsky.social · 16/06/2025

He accounted for infrastructure to go the longer distance from the network when avoiding threatened species. Don't think there would be a difference in storage requirements with the increased distance. Storage is mostly about the baseline cost of renewables the % increase is on top of that.

Bycatch reduction interventions are effective for improving marine species populations but very few studies report the impacts on fisher safety, and other fisher objectives. This is a major barrier to adoption. Great talk by Cindy Vargas @arizonastateuni.bsky.social at #iccb2025.

Matthew Holden 🏳️‍🌈 @matthholden.bsky.social · 16/06/2025

We can achieve 100% renewable energy in Australia & also protect threatened species impacted by wind and solar developments with only 2-3% increase in electricity bills compared to if we didn't consider threatened species. #iccb2025 great talk by A Rogers

I really dislike this sentiment re: AI impacts on education: If an assignment can be completed by AI then it is clearly just busy work; educators need to create better assignments. Absolutely not true. Just because AI can do something too doesn't mean that doing it doesn't have pedagogical value.
