While 'flashy' papers are great, analyses are ephemeral. It's the data, its preservation and organization that will persist. Honored to be involved with this amazing team on what I think are some of the most important biodiversity data out there. BioTime v 2.0.

You have my support!!

Jonathan Chase @jon-chase03.bsky.social · Mar 18

It's the 'replicability' part that worries me more, as we all know how many seemingly arbitrary choices can dramatically influence outcomes.

Jonathan Chase @jon-chase03.bsky.social · Mar 18

100% agreed. And these people are absolutely phenomenal, doing the hard (often thankless) work to ensure the next level of reproducibility.

Jonathan Chase @jon-chase03.bsky.social · Mar 17

I like the idea. A lot. But to be honest, I would be very afraid of the outcome.

I will use it in my classes

Is fragmentation bad or good for biodiversity? Yes!

We use a classical competition-colonization metacommunity model to show that fragmentation can increase or decrease diversity depending on the total amount of habitat in the landscape. 🧪

How biodiversity responds to habitat fragmentation per se is debated. Here the authors combine metacommunity simulations with reanalysis of empirical metacommunities to show that the amount of habitat...

Jonathan Chase @jon-chase03.bsky.social · Jun 12

After 6 years of postdoc-ing with us at iDiv, the Synthesis group says goodbye to Emma Ladouceur. She had such an incredible influence on us all, scientifically and personally. We will miss her, but wish her well and onto bigger and better things at the University of Prince Edward Island!

Jonathan Chase @jon-chase03.bsky.social · Jun 11

For those following the ongoing saga of Priyanga Amarasekare—a major update. She speaks out, addressing all charges! This would make for a dramatic novel or Netflix series. But no, it’s the life of our brilliant and deeply caring colleague and friend.

Congrats to all!

But super pleased to see the early career list has Melissa Guzman, whom I was privileged to help nominate (and work with; she’s a 🌟) and Diogo Provete, who is spending the next year at IDiv in my research group, on a Humboldt foundation sabbatical!

Congrats to Zhonghan Wang for leading this great study in Ecology looking at habitat fragmentation effects on the Thousand Island Lake islands across multiple trophic levels. Was great having him visit iDiv on a CAS scholarship from China.

Higher trophic levels and species with poorer dispersal traits are more susceptible to habitat loss on island fragments

Just to say the editor (*ahem*) also was nervous about this. But I’m glad they got the message out there in an appropriate venue. Still have no idea where the publishing landscape is going to take us.

Jonathan Chase @jon-chase03.bsky.social · Mar 21

"Amarasekare knows she could get in trouble for talking about any of this, especially to a reporter. But she said she’s tired of feeling muzzled by confidentiality rules and wants to restore her reputation."

www.chronicle.com/article/ucla...

UCLA Punished a Prominent Scientist for ‘Destructive and Harmful Conduct.’ She Says It’s ‘Unjust Persecution.’

Priyanga Amarasekare was suspended and later put on involuntary leave for breaching the Faculty Code of Conduct. She hopes that speaking out will help clear her name.

As director of CESAB, I'm incredibly proud to share the latest article of our postdocs today in Ecology Letters. 👏

They call for a more ethical academic publishing landscape but also ask to not let only the Early Career Researchers pay the price of this paradigm shift !

doi.org/10.1111/ele....

🧪🌍

The publish-or-perish culture in academia has catalysed the development of an unethical publishing system. This system is characterised by the proliferation of journals and publishers unaffiliated with learned societies or universities— that maintain extremely large revenues and profit margins diverting funds away from the academic community. Early career researchers (ECRs) are particularly vulnerable to the consequences of this publishing system because of intersecting factors, including pressure to pursue high impact publications, rising publication costs and job insecurity. Moving towards a more ethical system requires that scientists advocate for structural change by making career choices that come with risks, many of which disproportionately impact ECRs. We illuminate major issues facing ECRs in Ecology and Evolution under the current publishing system, and propose a portfolio of actions to promote systemic change that can be implemented by ECRs and established researchers.

🚨New paper! Is homogenization really that more common than differentiation? - not really, our latest work shows that one pattern can be as common as the other.

Another great work and collaboration led by this amazing team👇

Jonathan Chase @jon-chase03.bsky.social · Feb 22

The lack of evidence for declining local diversity through time must be because everything is homogenizing, leading to larger-scale losses.

Right?!

Nope, says our analysis of 500+ meta-communities through time just published in Science Advances

Synthesis reveals approximately balanced biotic differentiation and homogenization

Homogenization is most common at large temporal and spatial scales but is balanced by differentiation at smaller scales.
