Here’s another plant that stumped the @inaturalist.bsky.social model.

It’s natural position and s hanging straight down. Also from Amazonia, namely Putumayo, Colombia. Anyone know what this might be? 🌱 🧪

This crazy plant 🌱 stumped the @inaturalist.bsky.social AI model.
Can anyone help me with an ID?

Lovely. But don’t kid yourself. Toucans will also “make a snack” of baby birds right outta the nest. 😋

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:

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

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. 🤗

“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.”

Farewell to the master satirist and lyricist.
