How should the discipline of ecology and the community of ecologists respond to the ecological crisis? Is it time that these were put on something more akin to an emergency footing? www.cell.com/action/showP...

🔈 CALL FOR PAPERS IBIS Special Issue Collections-Based Ornithological Research in a Changing World Submission deadline: 30 June 2026 onlinelibrary.wiley.... #ornithology 🪶

NEW METHODS ARTICLE: Phylogenetic GLMMs open doors to study evolution of discrete traits. We show how binary models extend to ordinal & nominal traits, using bird data, and provide tutorials to make these methods accessible to evolutionary biologists: doi.org/10.1093/jeb/... Mizuno et al.

Have you ever wondered what you would find if you could keep your eyes on a bee for more than a few meters? Us, too! preprint (with videos!) + thread 🧵 Precise, individualized foraging flights in honey #bees 🐝 revealed by multicopter drone-based tracking www.biorxiv.org/content/10.6... 1/9

Preprint! Ever wondered why individuals within the same species migrate differently? Or what drives some animals to become partial migrants? Then, this paper is for you! Our new paper synthesizes the ecological and evolutionary mechanisms that shape partial migration. Link: doi.org/10.22541/au....

I have a new preprint demonstrating a genome-architecture-aware approach to inferring species trees and introgression landscapes from a small number of genomes. If you are interested in phylogenomics, birds, or hybridization, this is for you! www.biorxiv.org/content/10.1...

A quick reminder for everyone registered for SSB2026: please take a moment to complete the survey to submit lightning talks, sign up for workshops, and indicate your interest in other meeting activities. If you haven’t filled it out yet, today’s the day! We're excited to see you all in January!

We got published in Ecology&Evolution! We propose an equation from which we derive the fundamental equations of population ecology and evolutionary biology (the Price equation). #evobio #philbio onlinelibrary.wiley.com/doi/10.1002/...

Wutt!? New ecosystem service just dropped. Birds are fungi dispersers! And, even better, tapaculos are truffle dispersers! My week is complete.

Our special issue on Evolutionary Functions of Consciousness, coedited with Tecumseh Fitch and Adina Roskies, now online royalsocietypublishing.org/toc/rstb/202... Contributions by (1) Irina Mikhalevich; (2) Eva Jablonka and Simona Ginsburg; (3) Nicholas Humphrey; (cont'd)

I am extremely happy to see that our review on fossil tip-dating is out in early view in Systematic Biology! A huge thanks to all the authors of this massive project (@heckeberg.bsky.social, @basantakhakurel.bsky.social, Gustavo Darlim, and @hoehna.bsky.social)! academic.oup.com/sysbio/advan...

Our synthesis on patterns of bird diversity and diversification dynamics in South America is available online: books.google.com/books?id=lyi...

Our paper on tinamou evolution is finally out in @systbiol.bsky.social. academic.oup.com/sysbio/advan...

Yes - isometric scaling as a way to understand the benefits and costs of being small versus large. Haldane's Harpers article from 1926 is an amazing example of popular science writing.

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

This looks to be a fundamental theoretical advance by @jpodwyer.bsky.social et al. Using linkage disequlibrium-based Ne to back out σ² and then predict fluctuation sizes from a single temporal snapshot is a real advance for broad application 🧪🌐https://www.science.org/doi/10.1126/science.adu6396

Juncos and ginkgos! 🐦 🍂

Excited to share our new paper where we find that the rise, decline and fall of clades is not explained by the usual suspects (diversity-dependence, ecological opportunities) but rather by species' insidious loss of macroevolutionary fitness: www.nature.com/articles/s41... 1/3

New review out! With students in my lab, we explore how population size shapes speciation—from drift in small populations to selection in large ones. Do small or large populations speciate faster? The answer is more nuanced than you might think. esj-journals.onlinelibrary.wiley.com/doi/full/10....

Large citizen science datasets are powerful tools for biodiversity science, but they may have biases. Nice new paper from @louisbackstrom.bsky.social et al. showing that for eBird and Birdtrack lists there is a tendency for rare species to be over-represented onlinelibrary.wiley.com/doi/epdf/10....

Sad news: Jane Goodall has died. She did more than any other human for our understanding and appreciation of our closest relatives, the chimpanzees. That chimpanzees are Endangered tells you everything about our species and about what made her so exceptional. www.nytimes.com/2025/10/01/o...

Our new paper @asn-amnat.bsky.social develops a Grand Unified Theory including both exploitative and interference competition doi.org/10.1086/737628. The R* rule of ecology (that 2 species cannot coexist on a single resource), is widely broken, including via a new trade-off we describe. 1/9

super excited to share this big project with @daeaton.bsky.social out now in Systematic Biology! We derived distributions for -- given an arbitrary species tree model -- how far you have to move along a genome before observing a change in the underlying genealogy: doi.org/10.1093/sysb...

Unsolicited listicle: My list of the most criminally underused/underappreciated phylogenetic comparative methods. Note, I am not involved in ANY of these methods; but I see them as things people are often asking of comparative data but have been surprised at how infrequently they have been cited.

Excited to share our new paper on flight morphology and migration in North American wood warblers. Surprisingly, ground-dwelling warblers may be better adapted for migration than aerial ones!!! link.springer.com/article/10.1...

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!
