Second dissertation chapter just dropped at Ecology Letters! doi.org/10.1111/ele.70441 Across theory, stochastic models, and protist microcosms, we show how rising temporal autocorrelation drives predictable increases in extinction risk under warming (ft. coauthor @mtkummel.bsky.social!)

I am recruiting a PhD student interested in the disease ecology of cavity nesting birds to start Fall 2027! Interested applicants can contact me by filling out the linked form. I will also be at ESA 2026 and am happy to meet! More info on my website: sauerlab.com Please share!

I guess I'm Dr. Cody Limber now!

I'm defending my PhD this week! If you're interested in coming and hearing about the latest and greatest in feather research, send me a message and I can send you a zoom link!

#Evol2026 I’m launching a new research group at UNC Charlotte in January 2027. Prospective students, postdocs, and collaborators are welcome to get in touch: [email protected] More at jakeberv.com, lab website coming soon.

#NewPaperAlert! This one has a massive author list and has been a LONG time in coming, but is SO COOL! First, check out the first figure to get you interested! Manakins! Fruit! Sexual-selection in action (displays and Z:A chromosomal diversity)! Read on for the back story & link 1/n

Big milestone completed last week! Happy to share that my PhD dissertation has been successfully defended (ft. my fanciest PowerPoint yet and the longest LaTeX document I have ever had the (dis)pleasure of compiling)

One of my favorite parts of writing is reading old texts. Tiedemann 1810 wrote that feathers are of a vegetable nature since they are basically skin plants that sprout, grow, wither, and fall out each year. I'm pretty much convinced he was onto something

Some excellent (brown) naturalist finds recently! Never thought I'd see Eastern Hognose in CT but managed to find 2 while looking for butterflies

Hard to beat good looks at a Blackburnian Warbler

Lifer Swainson's Warbler this morning in Connecticut! First state record and I'm super glad it stuck around for a second day so that I could get to see it!

Interested in a PhD working on sexual selection in tropical shorebirds? I'm recruiting a student for Fall 2027! I'm happy to support an applicant writing a Simons Graduate Fellowship in Ecology & Evolution: www.simonsfoundation.org/grant/simons...

Sunbirds don’t drink nectar like hummingbirds. They use intralingual suction: the tongue acts like a straw, moving nectar via pressure differences rather than capillarity. A clear case of biomechanical divergence despite ecological convergence. doi.org/10.1016/j.cu... @CurrentBiology #ornithology

Second author on this paper is the incredible former Prum Lab undergrad Molly Hill!!!! Amazing stuff

I made a little android app to better explore what species are around! It's called Manakin (play on the Merlin app) and it lets you download and explore iNat data. It can also help you plan out trips and remind you when your target species is active.

This is a pretty fun read

Obsessed with the photos coming from Artemis II but haven't seen this one shared too widely yet, it might be my favorite! (Tons of other cool pics here: www.nasa.gov/gallery/luna...)

Not only is this language disgusting, but so are their actions. I'm really not enjoying answering every question from friends and family about my future with "hopefully I'll have more job prospects during the next administration..."

This is one of the most unhinged things I've ever read but also invents the field of gravitational ornithology so net positive I guess? arxiv.org/pdf/2603.29064

Excited to share a new paper doi.org/10.1098/rsbl... We suggest that tradeoffs between infection costs and the benefits of sociality are dynamic, context-dependent, and likely asymmetric within dyads. We then propose hypotheses about how these tradeoffs might shape social responses to parasites...

My new favorite paper: doi.org/10.1901/jaba...

I only have two science notes for the Project Hail Mary movie. 1) he doesn't balance the centrifuge and 2) the Hail Mary doesn't need solar panels, it's got astrophage for energy and is mostly flying in interstellar space. Other than that, it's a perfect film

For the past few years, I've been playing with the idea of creating a "naturalist calendar" which reminds you when its the best time of year to look for certain animals. I made a little test using iNat data today; codylimber.github.io/ct-butterfli...

Sometimes you just get that shot. Anna's hummingbird with a little friend, in my yard. Davis, CA. #birds #ants

Now with pages @systbiol.bsky.social ! "Social Environment and the Evolution of Delayed Reproduction in Birds" with @pseudacris.bsky.social and Rick Prum Some comparative support for the hypothesis that the evolution of complex social contexts restructure life histories doi.org/10.1093/sysb...

Anyone know a way to search my eBird photos for passeriformes? I know I could sort taxonomically and scroll all the way down but there has to be a better way right?

Warm weather and rain produced a pretty epic night of salamanders and frogs last night! Highlights were several huge Spotted Salamanders, 10 Four-toed Salamanders, and a single A. unisexual hybrid!

Submitted my 4000th complete checklist to eBird today! ebird.org/checklist/S3... Pretty wild to think of all the birds I've seen in that time. The birds today were nothing too remarkable, plenty of singing cardinals, some flyover geese, and the invasive trio!

Accepted at ESA's Front. Ecol. Env.! Prebreeding populations and the importance of life history for conserving imperiled seabirds with @ejgnam2.bsky.social Or, why juveniles, subadults, immatures (whatever you call them) are important even when critters have a """slow""" life history!

Thrilled to share that my first dissertation chapter is now published at Ecology! dx.doi.org/10.1002/ecy.... We embed TPCs into population dynamics to show how changing temperatures' ordering — not just its distribution — increases extinction risk (i.e. heatwaves matter!) @esajournals.bsky.social

Eastern Skunk Cabbage actually heats up to melt its way through snow and attract pollinators! I've always wanted to see this in action so I borrowed a thermal camera to photograph some plants this weekend. Sure enough, the spadix is glowing hot and plant was able to melt its way out of the snow

Some lovely snow around Yale University today!

Happy birthday to one of my favourite haters, Charles Darwin

Evolution of manakin plumage maturation now out early look @sse-evolution.bsky.social (Phylo-)Devo-evo, plumage, and social signaling Bonkers system that reshaped how I think about both development and evolution. doi.org/10.1093/evol...

I'm officially coining the term "cell type natural history" where the goal is to describe what cell types are out there, what they're up to, and how did they evolve

Come see me talk about feather coloration tomorrow at 11:30 at #SICB2026 Plus, you might learn the punchline to this joke!

It’s happening!! #SICB2026 Tomorrow, from 8AM to 3:30PM come to C120/121/122 for ✨Sex Across Origins: Questioning animal-centric assumptions and developing integrative frameworks.✨ Also! 3 fantastic complimentary sessions Tuesday in B113, with a special focus on education in the morning.

If you're bored and use iNaturalist, here's a link to a tool that displays which of your observations were the first recorded for a taxon. I apparently have 16 (out of 3,395). I need to get out more. 🌿 #inaturalist #nature #insects #spiders glauberramos.github.io/inat/first-o...

I posed recently about my recent obsession with Hooke's Micrographia (1665) and the incredible feather drawings it has. I really wanted to see an original copy and luckily, Yale has two! So, earlier this week, I headed down to the Beinecke Library with @mylestogo.bsky.social to check it out

I bumped into a very cool reference today! Micrographia by Robert Hooke was published in 1665 and is basically a bunch of descriptions of things seen while looking through a microscope

One of my favorite parts of writing is remembering that the perfect citation exists and even remembering what one of the figures looks like but not remembering any of the key words that make finding the paper possible

My feather cell type paper is finally out! doi.org/10.1111/ede.... We’ve packed a ton of stuff into this paper but I’ll go through some highlights in this thread!

🪶 Feathers are complex, each one an elegant structure crafted through millions of years of evolution. As habitats shrink and climates continue to warm, understanding the why and how of colorful bird feathers could help us better protect them into the future: go.nhm.org/feathers-work

Presenting tomorrow at #Evol2025, swing by to hear about feathers, cell types, and a little teaser about pigmentation patterns!

I hope to take a PhD student in the coming application cycle. Please reach out if you are interested in joining our lab in EEB at Yale, especially if interested in working on the natural history/ phylogenetics/ morphology/ population biology/ development/ genomics of siphonophores. dunnlab.org
