Our new preprint On a global scale, plants did not experience a catastrophic mass extinction during the Permian–Triassic boundary (PTB). However, they still suffered losses, with extinction rates reaching around 30%. doi.org/10.64898/202...

Better late than never 😅 Happy to share that the final paper of my PhD was out this February in @journalofecology.bsky.social ! We asked: what drives the functional recovery of seed rain as tropical forests regnerate after disturbances? 🫘🌿 @reassemblynet.bsky.social #restoration #forestecol

Deadline this Sunday!

Deadline this Sunday!

I'm excited to see @taphonomist.bsky.social's newest paper out @royalsociety.org. Our analytical investigations reveal an important cautionary tale about decay: what was believed to be the worlds oldest octopus remains (Pohlsepia) - is in fact, a highly decomposed nautiloid! Congrats again, Thomas!

I am so unbelievably proud to present 8 years of hard work: the worlds oldest octopus is not an octopus... Pohlsepia is actually a really rotten Nautiloid (but oldest soft tissue nautiloid ever found!). 🐙❌ royalsocietypublishing.org/rspb/article...

In March, Matt Ridley gave the inaugural "Scientific Freedom Lecture" at NIH, on a lab leak origin of COVID-19. The talk was so full of misrepresentations, omissions, falsehoods and lies that I will need several blog posts to debunk it. Here's Part I: pandemonium.hypotheses.org/995 🧪 #covidorigin

We have expanded our target capture dataset of the Senecio inaequidens - S. madagascariensis complex to a global scale. More clarity on the areas of origin of invasive madagascariensis, but also raising new questions. doi.org/10.1007/s105... @biolinvasions.bsky.social #asteraceae #compositae #weeds

Polypterids (bichirs + ropefish) are the sister lineage of all other living ray-finned fishes. Restricted to Africa today, fragmentary fossils show they inhabited South America until at least the Paleocene. Now Late Cretaceous finds add Madagascar to the list: www.sciencedirect.com/science/arti...

We are recruiting ! ... the second PhD position available with us at University of Manchester: www.findaphd.com/phds/project...

Come join us for a PhD at the University of Manchester :

Last month I attended the @tibsaarhus2026.bsky.social conference where I presented a poster on some of my DPhil thesis work and enjoyed discussing all things biodiversity with fellow biogeographers. Can't believe it's been four years since my first TIBS conference as a nervous 1st year PhD student!

Offering a few free commissions to improve my sci comm skills & portfolio. I can do hand-painted illustrations for figures, design infographics, and even sound design and music for research promotion or podcasts. jenisidwell.com #sciencecommunication #marinemammals #lifesciences #datavisualization

PGRs Amy Shipley (@sauropodlets.bsky.social) & Lydia Woods recently published a review in @globalchangebio.bsky.social showing that while today’s extinction rates aren't yet at "Big Five" mass extinction levels, they’re likely the highest seen in the last 66myrs. amdunhill.co.uk/2025/11/17/n...

New paper in Nature Scientific Data! 🌵 We introduce CactEcoDB, an open database integrating trait, spatial, environmental, phylogenetic, and diversification data for the #cactus family. We hope it enables research and grows as new data are made available. www.nature.com/articles/s41...

I've seen fossils in some remarkable places, but this takes the prize: the benthic foram Nummulites in the base of the Great Pyramid of Giza. These massive blocks were quarried from the Eocene Mokkatam Formation when a relictual population of woolly mammoths still lived on Wrangel Island.

Congrats Yago :D

Ancient Neotropical mountains are often framed as isolated “sky-islands". But are they? Using 13 plant lineages from the campos rupestres of eastern South America, we uncover extensive lineage sharing with surrounding lowlands driven by climate. Open access: doi.org/10.1111/geb....

Great thread on a cool animal and a major problem: where do sturgeon come from? I still wish we could find a Triassic acipenseriform, there are a few candidates. But, the Triassic presents a daunting challenge to parsing out lineages that are gave rise to the fishes we have today.

Great thread!

Out now in Contributions from me and @gilespalaeo.bsky.social, a deep dive into an early member of the sturgeon and paddlefish lineage. Bear with me, but there’s a long backstory highlighting uncertainty about the anatomy of living species and how well-studied fossils can still yield new insights.

New paper out from @hoehna.bsky.social Lab, led by the brilliant @bjorntko.bsky.social! We applied the Pesto software (Kopperud & Höhna, 2025) to look at lineage-specific shifts in diversification rate on large, densely-sampled phylogenies across the Tree of Life doi.org/10.1093/evle...

Our new paper is now out showing how time perception in animals is linked to their ecology. Using data from 237 species we show temporal perception is faster in species that fly and pursuit predators www.nature.com/articles/s41... 🌐

We know that marine fishes 🐠 have an inverse gradient of speciation compared to that of spp richness, with higher speciation at higher latitudes. But, what about freshwater 🐟? Find out in the new PhD paper by Juliana Herrera-Pérez and friends (not just colleagues) 🤿 👇 shorturl.at/zgKfA

Our new paper revealing major patterns of diversification across the Tree of Life is here! doi.org/10.1093/evle... Congratulations to @bjorntko.bsky.social for leading this ambitious effort, it was a pleasure to contribute alongside @acapomorphic.bsky.social, @hoehna.bsky.social & Luis Palazzesi.

Our new paper 'A covarion model for phylogenetic estimation using discrete morphological datasets,' is out in SysBio! We introduce the "covariomorph" model in RevBayes to capture character and lineage specific rates of morphological traits. 🔗 doi.org/10.1093/sysb...
