Our newest paper is out in Methods in Ecol Evol @methodsinecoevol.bsky.social :) amazing team effort - we show that the traditional way of analyzing comparative data lacks finesse. besjournals.onlinelibrary.wiley.com/action/oidcS... w/ @itchyshin.bsky.social Yefeng Yang, Losia Lagisz & Ayumi Mizuno

of heteroscedastic variance to meta-analytical heterogeneity can uncover hidden patterns in variability, including systematic trends in between-study variation. Stay tuned for our future papers where we will keep convincing y’all to adopting location-scale modelling as your default approach to data.

Our recent paper looks at location-scale interfaces in comparative data. But predicting variance in variance extends much further - if you still have not have a look here onlinelibrary.wiley.com/doi/full/10.... (another recent paper in @globalchangebio.bsky.social). We show how extending the idea

Location‐Scale Meta‐Analysis and Meta‐Regression as a Tool to Capture Large‐Scale Changes in Biological and Methodological Heterogeneity: A Spotlight on Heteroscedasticity

Meta-analyses are widely used to understand how species and ecosystems respond to global change, but most assume that variability among studies is constant. This assumption can hide important biologi....

Are we doing simulations wrong? This paper convinced me we are. doi.org/10.1098/rstb... Usually we run 2 sets of "worlds" w and w-out intervention. Gives large uncertainties that include negative (harm) effects of interventions that are actually always positive (beneficial)!

Figure 5. Time series showing cumulative number of cases averted at each time caused by the intervention calculated using our method (single-world) and a
standard method. Shaded regions denote 90% confidence intervals. Note that there is more variation in the middle of the epidemic, so it may seem as though the
number of cases averted is large during those times. (Online version in colour.)

I’m sad to hear the news that the wonderful Jane Goodall is no longer in the world. Her work with chimpanzees at Gombe in Tanzania taught us to look at other apes - and ourselves - differently. I was privileged to meet her later in life and tell her what an inspiration she was to me.

The models are notably more complex but fittable with modern Bayesian GLMM routines. Think of them as looking at mean and scale (usually variance) evolution along the tree, here in an example of two concurrent Brownian Motion dynamics driving diversification of both variance and means.

By extending the comparative model we can assay the evolutionary signal in evolvability itself and test a number of biologically interesting trait configurations (codivergence, contra-divergence, ceiling effects, phenotypic integrations and more!)

I am just back from a wonderful few days in Sweden where I visited the incredible Lars Jonsson exhibition in Stockholm, and then his museum on Gotland. Absolutely mind blowing, the selection and range of work was just unbelievable!

like to contribute to a potential art&sci symposium at some next meeting (eseb or other) - let me know, I’m always happy to chat with art-inclined folk. Also don’t miss EvoKE conference in Athens! evokeproject.org/evoke2025-at... and join @evokeproject.bsky.social if outreach is ur thing;)

I keep saying scientists are amazing artists and again this tuned out to be true :) the art corner at @eseb2025.bsky.social organised by @evokeproject.bsky.social went great, I’m thrilled to see all your amazing pieces! If you’re interested in discussing art&sci in science communication or would

@eseb2025.bsky.social art corner goes well, it will be available throughout the conference. Join us, draw your science :) @evokeproject.bsky.social I get asked - what if I can’t draw? That’s even better! Trust me - your art will be more honest, and awesome. And we want to see it:)

At @eseb2025.bsky.social please go and visit the art corner organised by @evokeproject.bsky.social (6th Eseb art&sci corner!:)) It’s in the far back-right of the poster area. You don’t have to be an artist! No prior art knowledge required ;) just go there & draw/paint whatever portrays your science!

The art corner has been present at Eseb congresses since the 2015 Lausanne meeting, always receiving positive and lively feedback from all of you:) below some artworks from the Prague 2022 meeting. @eseb.bsky.social As always done with the amazing @evokeproject.bsky.social

At @eseb2025.bsky.social - as during previous eseb conferences, we will try to express our artistic selves. The art&science corner available to all and ready to take your artistic visions of science will be live starting from Tuesday morning. More details soon, here and in the conference app.
