Simulated trait distributions for two groups with different shapes. Top left: distinct skewness. Top right: distinct kurtosis. Bottom: different correlations between two traits for two groups.

Differences between M & F are pervasive, but we often focus on #SexDifferences in the mean. @pietropollo.bsky.social @danielwanoble.bsky.social @itchyshin.bsky.social &co present #stats tools that allow comparison of #skewness, #kurtosis & correlations b'n groups @plosbiology.org 🧪 plos.io/4093nJs

A comprehensive meta-analysis of exogenous estrogen, progesterone, and testosterone in animal models of ischemic and hemorrhagic stroke - Biology of Sex Differences Background Exogenous sex hormones have been extensively studied for their influence on stroke risk and outcome. This meta-analysis served to update the pre-clinical acute ischemic stroke (AIS) literat...

So excited to announce my most recent project is now in press!

Our meta-analysis looks at the effects of exogenous #estrogen, #progesterone, and #testosterone in pre-clinical models for 3 subtypes of #stroke: AIS, ICH, and SAH.

Does human disturbance disrupt predator-prey temporal niche partitioning? Today in @natcomms.nature.com
we show that while there is no overall effect, the larger species of the dyad "loses" the temporal response race to humans.

Continuing our series on difficult comparative models - and how to address them properly - we’re 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

We have an updated version of this preprint, available at:

Fingers crossed the formal, final version will be out soon.

We think this highlights a major issue in how we study behavior (& more).

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....

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

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!)

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.

Have you always thought about running simulations to make sure your models work the way you want them to? The new squidSim can help!

I'm very impressed with how @joelpick.bsky.social led this project and with the amazing final result!

Casual Chat with Dr. James Steele YouTube video by AASPT

Clearly I'm grumpy about the state of research in the field atm, particularly how power analyses are performative and hypothesis testing is butchered... so resharing this chat I had with @runbabyo.bsky.social et al. where we talk about these topics www.youtube.com/live/b0rXmtx...

Please consider applying to our open faculty position call that includes Ecology!
