Excited to share our new preprint on noise and determinism in Trinidadian guppy population dynamics! Thanks to all collaborators: Ron, Joe, Arshed, Dave & Simon. We develop a framework for quantifying how stochasticity alters equilibrium structure, stability and vulnerability to perturbations. 1/5

Our new preprint on the stochastic population dynamics of Trinidadian guppies is out! Proud to have been part of this collaboration, led by @harmanjaggi.bsky.social www.biorxiv.org/content/10.6...

Here is a blog post on our recently published paper on collective movement with stopping: arshednabeel.github.io/blog/flockin... (Short thread follows)

Our work on collective movement of individuals who can stop is now out in Physical Review E! We show that stopping can lead to ordered collective movement through a surprising new mechanism. go.aps.org/4aJrftm

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

Google's NotebookLM is one of the few times that AI has pleasantly surprised me. Especially with its new feature of creating slide-decks from sources you upload, it's an incredible tool for self-study.

This week, we are highlighting Rohini Balakrishnan, a @jexpbiol.bsky.social author, Editorial Advisory Board member and a part of the first cohort of JEB Travelling Fellowship recipients, as an extraordinary biologist. #100biologists

How Randomness Can Flip Evolution: New Study Uncovers Surprising Role of Population Noise Summary & Analysis by Tahirah Williams of “Eco-Evolutionary Dynamics for Finite Populations and the Noise-Induced Reversal of Selection” by Bhat et al. www.amnat.org/an/newpapers...

Full House brainstorming about Projects at the Konstanz School of Collective Behavior . What an amazing group of Students . Each student works on a project to be presented at the end of the school @cbehav.bsky.social

I recently learned that people may be using em-dashes (—) as one of the tell-tale signs for AI generated text. Now I have to consciously avoid using them in emails etc. I liked my em-dashes! 😞

Nabeel et al. present a method to derive models of theoretical ecology from stochastic time series data. This data-driven method may help empirical tests of ecological theories and to discover unknown principles. Read now ahead of print! www.journals.uchicago.edu/doi/10.1086/...

After languishing in the peer-review purgatory for over two years, our work on discovering dynamical models from time series data is finally out in @asn-amnat.bsky.social! www.journals.uchicago.edu/doi/10.1086/...

We finally got a ChatGPT generated review on a manuscript. So I wrote about how we handle these reviews is a sign of whether we have given up on peer review altogether.

So elegant! Back in the day when I was a CS masters student, streaming algorithms were of my favorite things in our graduate algorithms course.

Do you work with individual-based models of birth, death and movement? We have a review paper for you, part of a special collection for the journal Interface’s 20th birthday! doi.org/10.1098/rsif...

This past week, I had a pleasure to attend and teach a tutorial session at the ICTS-ICTP Winter School on Quantitative Systems Biology. Fascinating school, opened my eyes to the amazing world of theoretical community ecology.
