Flying past Mars, slaloming through the asteroid belt, then frontally towards Jupiter. This is how I'd imagine a soundtrack for such a trip. www.youtube.com/watch?v=dIww...
Fantastic discussion lecture at @mpidr.bsky.social by @rmcelreath.bsky.social π
I cannot agree more with @ezagheni.bsky.social who introduced the guest as a true renaissance scientist of today π
Very thought provoking. I hope it will add to the collection of those "embarrassing" YouTube footage π
This is figure 3, which shows Queensland rainforest plot locations, long-term climate, and causal diagram of the hypotheses relating climate variations over time to ΞAGB.
A study in Nature reports that a transition from carbon sink to source for the aboveground woody biomass of moist tropical Australian forests has occurred, driven by increasingly extreme climate anomalies. go.nature.com/4ndWLmg βοΈ π§ͺ
Wow! A paper on Wheatear plumage evolution in @science.org - unforeseen collision of interests here

#sortee2025 conference is on! Excited to see all amazing talks :) sortee.org/upcoming/
As always with priceless support from @jagiellonskiuni.bsky.social @ioes-ju.bsky.social @unsw.edu.au , with amazing @itchyshin.bsky.social and other non-bsky-ers ;)
data structure (make sure your categorical data is sufficiently balanced and all categories are represented at the key intersection of predictorsβ values); data complexity: collapse/merge levels if itβs reasonable to increase parameters identifiability.
unordered ordinal. Categorical data pose many challenges but they are as tractable with comparative methods as more well-behaved Gaussian models. The most important issues to keep in mind are: data availability (attempting to fit multinomial models with small datasets may lead to spurious results);
Continuing our series on difficult comparative models - and how to address them properly - weβre happy to showcase another study, this time in @jevbio.bsky.social academic.oup.com/jeb/advance-... We will guide you through a series of increasingly complex models, from binary, through ordered to

Follow us (incl @itchyshin.bsky.social and other co-authors not yet on Bsky ;)) for more useful methodological tips applicable to synthetic data. With support of @unsw.edu.au @jagiellonskiuni.bsky.social @ioes-ju.bsky.social @ncn.gov.pl @ualberta.bsky.social )
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 yβall 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
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.)
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)!
Iβm 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!)
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

Iβve recently had my Swarovski cleaned, adjusted and resleeved free of charge. I request the front lens covers almost yearly (their rubber attachments break easily) - wondering when theyβll lose patienceβ¦
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!
Our recent paper now live in Frontiers in Zoology @springernature.com - we show how climatic trends affect reproductive success of flycatchers in the Gotland population (nearing 50 yrs of continued monitoring ;)) link.springer.com/article/10.1... @ioes-ju.bsky.social @jagiellonskiuni.bsky.social
It's been a busy summer for our scientists. Several of them attended the #ESEB2025 conference in Barcelona.
With #eseb2025 coming to a close, it is time to start making plans for 2026. Interested in the interface of evolution 𧬠and ecology π³? Come to our #ExE conference hosted by @uniexecec.bsky.social in beautiful #Cornwall. Leave your email address at tinyurl.com/EvolxEcol to join our mailing list!
like to contribute to a potential art&sci symposium at some next meeting (eseb or other) - let me know, Iβm always happy to chat with art-inclined folk. Also donβt 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, Iβm thrilled to see all your amazing pieces! If youβre 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 canβt draw? Thatβs even better! Trust me - your art will be more honest, and awesome. And we want to see it:)
