Alt EN: Image shows a large green and brown American bullfrog partially submerged in bright green duckweed, with only its head and eyes above the water. Text on image: “Inform invasive species management. Sequencing invasive amphibians, like the American bullfrog, helps track introductions, spread, and rapid adaptation.” Alt ES: Imagen de una rana toro americana grande, verde y marrón, parcialmente sumergida entre lentejas de agua verde brillante, con la cabeza y los ojos sobre la superficie. Texto en la imagen: “Informan la gestión de especies invasoras. Secuenciar anfibios invasores, como la rana toro americana, ayuda a rastrear introducciones, expansión y adaptación rápida.”

Alt EN: Image shows a smooth, legless caecilian lying on wet soil and leaf litter in a forest floor setting. Text on image: “Fill major gaps in the Tree of Life. Amphibians remain underrepresented in genomic databases. Sequencing them strengthens phylogeny and comparative research across vertebrates.” Alt ES: Imagen de una cecilia lisa y sin patas sobre suelo húmedo y hojarasca en el suelo del bosque. Texto en la imagen: “Llenan grandes vacíos en el Árbol de la Vida. Los anfibios siguen poco representados en las bases de datos genómicas. Secuenciarlos fortalece la filogenia y la investigación comparativa en vertebrados.”

🧩 From #salamanders with some of the largest, most complex genomes to #invasive species like the American #bullfrog, #amphibian genomics is pushing #sequencing forward — while filling major gaps in the #vertebrate Tree of Life.🧬💻

Big thanks to @crawfordaj.bsky.social for helping shape this post! 🧬✨

Dems scapegoating again rather than taking a good long look in the mirror. Or looking at data 📊
like # of Dems that voted Green vs # of Dems that voted Republican in Florida in 2000. Dig it. 🪏

Time to publish responsibly: DAFNEE, a database of academia-friendly journals in ecology and evolutionary biology Abstract. The current economics of scientific publishing reveal a profound imbalance: academia pays prices far exceeding the actual costs of publication. R

Responsible publication of your research!

To help you do this @nicolasgaltier.bsky.social and coauthors have put together a handy database of academia-friendly journals, DAFNEE. You can read about it in their article recently published in @jevbio.bsky.social:

That’s still true today … depending on what country you live in ;-)

“Dictador” (or ‘dictator’ in English) brand rum from Colombia— this variety is labeled ‘Orange’.

Could it be that the popularity of the Orange Dictator brand is falling sharply?

🍹 cheers.

Rudolf Meier paraphrases a post from @rdmpage.bsky.social : as ~ 2/3 of the records in GBIF are birds, @gbif.org is primarily a Global Bird Information Facility. To correct this bias, we need to focus on the “ugly” biodiversity. 🪰 🪱 🪳 🦟 @mfnberlin.bsky.social #LivingData2025 x.com/rdmpage/stat...

Songbirds play optical tricks to make their feather colors ‘pop’ Concealed black or white bands on feathers boost the vibrancy of bird plumage

Pick an idiom: "more than meets the eye", "beauty more than skin [feather] deep" etc.

In work led by Rosalyn Price-Waldman, we describe a hidden (and ignored!) black or white layer found below the visible surface of bird feathers which helps make bird colours so striking!

That frog in the photo is the famous Red-eyed Tree Frog (_Agalychnis callidryas_) from the Caribbean side of Costa Rica — yet no one (!) is currently working on a reference genome 🧬 for this 🐸. However, we have a group of researchers trying to make this happen. If you’d like to help out, DM me. 🤗

Damn the fascist and complicit GOP.

“We've gained notoriety
And caused much anxiety
In the Audubon Society
With our games
They call it impiety
And lack of propriety
And quite a variety
Of unpleasant names
But it's not against any religion
To want to dispose of a pigeon.”

‘Half the tree of life’: ecologists’ horror as nature reserves are emptied of insects A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides

The legendary Janzen & Hallwachs on the collapse of insects. “It’s the same sheet, same lights same place, looking over the same vegetation. Same time of year, same time of the moon cycle, everything about it is identical... There’s just no moths on that sheet.” www.theguardian.com/environment/...
