Do I know any journalists interested in covering a story about a highway and the last population of a frog? Please message me
Part of our work was highlighted here: "Animals that eat poisons and don’t die". Take a look and enjoy the great Amazonian snakes that feed on poisonous frogs 🐸🐍!! @rdtarvin.bsky.social knowablemagazine.org/content/arti...
Animals that eat poisons and don’t die
Critters consuming species that contain deadly toxins have evolved a suite of clever strategies to keep out of harm’s way

The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.
Why are amphibian genomes soooo big? Let’s ruminate at 4pm #Evol2025
Dr. Rebecca (Becca) Tarvin@rdtarvin.bsky.social · last yr.Later that day I’ll tell you about why dendrobatid poison frogs have the largest and smallest anuran genomes measured to date! 🐸🧬 Tues June 24 4:00 pm Parthenon 2 7/7 #Evol2025 link to paper: doi.org/10.1093/evol...

Two more! 🐸 The activity involved both building dating profiles and then SPEED DATING among participants. It was very funny. 4/4
I really loved the creativity of the participants & look forward to doing the activity again with different groups! At some point we will post it on @amphibiaweb.bsky.social for everyone to use! 🐸 Warnings: some content is for adults only. Some content not scientific or validated! 3/4
