Why are amphibian genomes soooo big? Let’s ruminate at 4pm
#Evol2025

After lunch, come digest and think about frogs eating toxins — 2:45 today #Evol2025

Tonight! Toxic flies?! Come to the poster session to chat about flies adapting to nicotine

#Evol2025

In 20min ! #Evol2025

Hoy! Today!

No herp skills required !
Come at 5:30 and do some fun networking & win prizes. See you there froggos 😎

if you're thinking of going to the science in solidarity event, which is at the same time, I think we can squeeze bingo into the first 30 min of the time slot :) come by!

Calling all herpetologsts and friends at #Evol2025 — @amphibiaweb.org is hosting a meetup on Saturday from 5:30-6:30 in Oconee River 1. Come play herpetology bingo with us 😂 and win amazing prizes! 😮

please share or I will have to take all the prizes myself 🥹

🐸🧬

Later that day I’ll tell you about why dendrobatid poison frogs have the largest and smallest anuran genomes measured to date! 🐸🧬

Tuesday we have two talks. First is Adri Jeckel who will provide an enticing first look at toxin feeding experiments in Epipedobates poison frogs. Can juveniles 👶 sequester as much toxins as adults? Come find out!

Tues June 24 2:45 pm Parthenon 2

Monday evening during the poster session Sophie Draper will share some of the results from our mad scientist project to evolve chemical defense in fruit flies 🤯🪰

Mon June 23 5:45 pm Grand Hall 2-7 D17 (23rd)

5/7 #Evol2025

Then in the same session María José Navarrete Méndez will present NEW data exploring the evolution of chemical defenses in the increíble harlequin frogs 🐸and the possible involvement of bacteria 🤔🧫

Drosophila Genetic Database The Drosophila Genetic Database, FlyBase, is on the brink of collapse due to the sudden termination of the FlyBase NIH grant, which includes salaries for 5 literature curators based at the University ...

Flybase lost all of the NIH support overnight - it is a disaster for the community. Please consider donating. I just did! www.philanthropy.cam.ac.uk/give-to-camb...

"Your reps (esp. dems) are cut off from info. coming from fed agencies under the executive branch. They are learning about science cuts from us, or from the media, so when you learn about terminated grants, interference in free speech, etc, call or mail your reps to inform them."

4/4

"Focus your letter writing and phone calling wisely, on those in power (GOP), and on those who need to be persuaded (GOP). So those of you in “red states” are most important in advocating for science. Find common ground with opponents of science funding to try to persuade them."

3/4

"Send your representatives specific, personal, heart-warming stories of the benefits of science funding, and also examples of the harm done by cuts to science. Be sure it connects with everyday lives in ways anyone can relate to."

Being a field biologist means embracing uncertainty, rolling with the punches, and keeping up a positive demeanor. That's why field biologists are so fun!! Cheers to y'all <3 🐸🌿🧪
