Decline in body mass in adult (left) and nestling great tits. In the nestling plot, the purple line represents all nestling and the green line those that recruited to the population as breeders. Their different slope suggest an increase in the strength of selection on nestling mass something confirmed in the MS by analysing the temporal trends in selection differentials (see link for further information)

We have published a new pre-print showing a decline in great tit adult and nestling mass of around 1 gram in 47 y. [rate of approx. -0.040 Hadanes] With @ellafcole.bsky.social, @devisatarkar.bsky.social, Sam. Crofts, @mcmahok.bsky.social & @sheldonbirds.bsky.social www.biorxiv.org/content/10.6...

When studying animal physiology we carefully control temperature, oxygen…but often ignore who animals live with.

Social context such as parents (1), social environment (2), litter mates (3) can shape physiology and later plasticity (4). We discuss it in this commentary 👉 doi.org/10.1242/jeb....

With headlines that the University of Alberta will "abandon race-based" admissions policies, remember that anti-EDI framing is designed to make it seem like the pre-EDI status quo is somehow 'neutral'. In reality, by abandoning sensible EDI policies, institutions are *doing* race-based admissions.

Replication studies: a win-win for early-career training and behavioral ecology Replicating previous research builds confidence that results are real and meaningful. But close replications are rare due to limitations in resources and d

How do we know our research results are REAL? We replicate them! Most folks agree but lament on how hard it is to publish these replications.

My dearest gentle reader, lament no more! Delighted to unveil: Replication Studies, a new section of Behavioral Ecology 1/

This is great! And I love the suggestion of using replication studies as a training opportunity for graduate students.

iDiv Leipzig is organizing a symposium for early career researchers from all fields interested in scientific integrity & reproducibility.
Some good stuff, e.g.: @haesleinhuepf.bsky.social on generative AI for science, @rmcelreath.bsky.social on a guerilla approach to scientific workflow.>

I hope to see some of you in Bielefeld for this upcoming workshop on measuring and modeling plasticity. ECRs in and around Germany with a penchant for statistics should consider applying while spots remain available!

I am looking for a PhD student to join my new Socio-Eco-Evo group, hosted in Katie Peichel's Evolutionary Ecology Division @ University of Bern. We're offering a fully funded 4-year position, studying social plasticity and behavioral adaptation among stickleback in Greenland. Please share around!

network showing more diverse connections over time for editors and reviewers

cover of the paper with title and authors

last paragraph of the abstract: Synthesis and applications. Our results show that editorial diversification is a practical lever for making peer review more inclusive and better aligned with the global distribution of ecological research. These changes make the publication process fairer and improve the quality and global impact of the papers published.

New paper, Great news:
We have been saying for years that making the editorial board more diverse was needed
We now show that diverse team of editors makes for more diverse reviewers
More Inclusive=Better Science
Things are getting better on this❤️

Sharing reliable public opinion polls that illustrate the unpopularity of the government's policy moves also helps demonstrate that "the people" aren't really on their side.

That's why the UCP continually refuses to release their own govt polling on the pension plan and police force.+

Back in school, I wrote an essay about how two-tier healthcare would improve access for everyone.

It makes intuitive sense: create a second line and the original one gets shorter, right?

A better look at the evidence and arguments like Picard's changed my mind. 🧵
