Super excited to share the first preprint from my PhD! In this, we couple species range maps with daily-scale climate records over the last 80 years to produce the ClimLimits database, a record of 44 realized climate limits for ~55,000 terrestrial and freshwater species. (1/4)

It's kind of like GeoGuessr but instead of images, you see a bird list :) You can play older days in the archive, and there's also "free play" where you can play this infinitely with random checklists! There's also shareable scores so you can compete with your friends, here's mine from today -

(4) As a user, you can control what exactly is visible, with private collections, and choosing which shelves to display. (5) You can also make shared collections with friends; any paper added here auto-syncs to the shelves of all users- perfect for group reads or collaborative projects!

It’s still in beta, so I’ll keep building new features over the coming weeks (next up: seeing friends’ paper reviews), but I’m really excited to bring this into the world! I’ve always loved hearing about my friends’ research, and it’s fun seeing what people are reading and getting excited about.

Marginalia is full of features to streamline your trails of academic papers, and see what your friends are up to. Think of it as GoodReads but for papers! Here's some features I think are cool - (1) Look up papers by doi or title to add them to three shelves - read, up-next, and to-read.

(2) For papers you've read, you can track what you liked/disliked about them, and give them ratings. You can also sort papers across into sub-collections based on different projects you're doing! (3) By adding friends' usernames, you can see a social feed of what your friends are reading.

I was interviewed by @plosclimate.org's Latitude blog about my PhD research and the nexus of climate change and ecology - where do we train our eyes, and what do we still need to know to think about the future of biodiversity? Thanks to PLOS Climate & @jamiemales.bsky.social for this opportunity!

New on the Latitude blog: the latest in our series of interviews with climate PhD students! This time, we speak to @krishnasg.bsky.social of @isemevol.bsky.social about his work on tipping points, biodiversity & ecosystems within the @climtip.bsky.social consortium latitude.plos.org/2026/09/plos...

New in PNAS today: we projected how climate change will reshape the body size of marine life across the entire ocean. 23,329 mollusc species, every ocean basin. The headline everyone expects is "life shrinks." The real answer is far stranger. 🧪 #marinelife www.pnas.org/doi/10.1073/...

My brilliant friends Saismit and Satavisha wrote an article for Times High Education about being a more effective and active ally to women and underrepresented minorities in academia! Synthesizing evidence across different aspects, they then trace out actionable steps as to what to do to address it.

As I & @satavisha-de.bsky.social , move up the career ladder, the tampons in the bathroom may increase, but the women around us do not. Despite policies meant to patch its cracks, academia continued to sieve out women. We saw it, we heard it from our peers. So we looked for the literature.

It’s been a lot of fun working with Vasilis and Claire on this! We hope that the ClimLimits database will be a useful tool for physiological or macroecological syntheses of realized niche limits, and to assess how these limits may be changed or breached in the future. (4/4)

We find climate limits for each species as the most extreme historical conditions experienced across several aspects of temperature/precipitation - maxima/minima at different timescales and thresholds, max. annual variability, and maximum frequency, intensity, and duration of extreme events. (2/4)
