Packard Fellow and Johns Hopkins University scientist Dr. Jasmina Wiemann is working to understand how living organisms respond to planetary change by developing innovative ways to read molecular “memories” preserved in ancient organisms—helping fill some of the blank pages in the history of life.

New paper from my lab @cudenverclas.bsky.social, led by HIGH-SCHOOL student Serene Park! We studied a moth that migrates from the Great Plains to the Rocky Mts (and back) each year and tested if they are harmed more by extreme heat or low O2 🧪🌍🐙 resjournals.onlinelibrary.wiley.com/doi/10.1111/...

‘tis the season to celebrate the many animal species that reproduce via parthenogenesis - or reproduction from an unfertilized egg. Pictured here are 3 species of all-female, parthenogenetic gecko: Mourning Gecko; Bynoe's gecko; & Indopacific slender gecko #MerryChristmas #Herpetology 🎄🧪🦎

New paper out today in @royalsocietypublishing.org Biology Letters, led by undergrad superstar Laina Weiss! An experimental test of theory on the effects of temperature and resources on carrying capacity. So proud 🥹 tinyurl.com/yvmzmt9a @integrativebiology.bsky.social

On the fifth day of Christmas, Linnaeus gave to me...FIVE ANOLES! Well, more like anoles adapting to temperature change in the Andes, as taught to us in this lunchtime lecture! Kicking off the journal series, it contributed to the 1000+ lecture attendees this year! 🌍🧪Check it out👇 buff.ly/Tgjn9Pk

True toads (Bufonidae) originated in South America and invaded Africa via the Antarctic in the Cenozoic! (which was temperate/sub-tropical at the time). Super cool. 🐸🐸🐸 royalsocietypublishing.org/rspb/article...

I love Letters to a Pre-Scientist week! This round, my pre-scientist pen pal (whose stem interest was "not at all") asked me about cool lizards. I doubt they've ever seen this buff worm! (Mexican worm lizard, Bipes biporus)

Excited to share our new Fire Ecology study! 🌲🔥 Terrestrial lidar can rapidly and accurately measure crown scorch 20x faster than traditional methods. Our R package, CrownScorchTLS, helps make this method accessible for large-scale forest monitoring. doi.org/10.1186/s424...

Curly-taileds are some of my favorite lizards, but unfortunately we don’t have them in Georgia… or do we?? One of the best things I’ve found in a cracker barrel parking lot! Check it out now in Reptiles & Amphibians journals.ku.edu/reptilesanda...

12/12 What's clear: we handicap ourselves by studying organisms in environments dramatically simpler than where they evolved. What other fundamental discoveries await scientists willing to bring ecology into the lab?

By combining mark-recapture and genetic parentage data from wild #lizards, we show that the offspring of older parents do not have lower survival or reproductive success than the offspring of younger parents: doi.org/10.1093/jeb/... Crain et al. 2025

Always repost brown anoles but especially if it's a Miami brown anole 🦎🦎🦎

Applications are currently being accepted for UBC's ✨️ Biodiversity Postdoctoral Fellowship ✨️ (two positions!!), due Jan. 15 Please share far and wide 🚀 (See thread)

New paper out today in Ecology Letters! In this synthesis we dive into the equilibrium assumption in ecology - why it's everywhere in ecological theory, the evidence for it in nature, when meeting the assumption is important, how to achieve it in empirical research, and more! tinyurl.com/yh6kyysm

How did the study of little brown lizards lead to advocacy for more engaging science communication? Anole Annals was an important stepping stone along this path.

Congrats @raularayadonoso.bsky.social !! 🦎🦎🦎

I wrote about an absolute diva defector.com/fat-and-sass...

Remember remember the 5th of...December? Islands are central to our understanding of ecology & evolution, from the theory of natural selection to community ecology. This special issue promises to provide a synthesis of the latest research, and there's still time to submit! 🌍 🧪 👇

Always love working down in Fairchild Tropical Botanic Garden. Catching some great lizards all day every day and teaching high school students how we use them to study ecology and evolution. Can’t imagine a better gig!

Bumping this up one last time. I'm looking to hire graduate student(s) to work on an NSF-funded project to study elevational range shifts among dragonflies here in Colorado. @cudenverclas.bsky.social 🧪🌍🐙 Applications will be considered until Nov 1. See post below for more details

Great time talking to 50 10th graders from Miami's BioTECH high school about lizards and how we study them for our ecological and evolutionary research! 🦎🦎🦎 @gtresearch.bsky.social @gtsciences.bsky.social

Darwin's Darwin finches (the island is called Darwin, that's not a typo) have been variably described as either two species, or combined into just one. But what's right? As part of our #SpecialIssue on Evolution on Islands, Peter & Rosemary Grant took to answering this...(1/2) 🌍🧪

Had the most amazing morning talking to the next generation of lizard biologists in Miami, Florida! Hopefully inspired some future lab members! 🦎🦎🦎

I’m beyond honored and thrilled to have been selected in the 2025 class of #PackardFellows - what a dream!! 😀 No better way to spend it than right here on Lizard Island with an A+ lizard catching team!! 🦎🦎🦎 Honored to be such an amazing cohort: www.packard.org/2025fellows @packardfdn.bsky.social

Such a cool paper. And, fascinating to think about in the context of aging organisms that compensate for deteriorating abilities with age and *thrive*

Neat study on the other type of limb loss. Also, under the right conditions, apparent disabilities may not be disabling!

@cudenverclas.bsky.social PhD student @sarahnalley.bsky.social was featured on the local news talking about her dragonfly research in @natclimate.nature.com! 🧪🌍🐙 www.9news.com/video/tech/s...

Congratulations to @jameststroud.bsky.social for being selected for a 2025 David and Lucile Packard Foundation @packardfdn.bsky.social Fellowship in Science & Engineering! Its a wonderful organization and a well deserved recognition!

My colleague @jameststroud.bsky.social is a fantastic scientist and an even better guy -- congrats James on this richly deserved recognition and research support!!

Congratulations to @jameststroud.bsky.social on being named a 2025 #PackardFellow by @packardfdn.bsky.social. Stroud will receive $875,000 over 5 years to fund his pioneering research in evolutionary biology — studying 1,000 backpack-wearing lizards in South Florida. Read more: bit.ly/3KNrVU5

We’re thrilled to announce the 2025 class of Packard Fellows for Science and Engineering — 20 innovative early-career scientists who will each receive $875,000 over five years to pursue their research. Meet the 2025 Packard Fellows ⬇ www.packard.org/2025fellows

Welcome to all the new Packard Fellows- this is an incredible community. I look forward to meeting you at the reunion! Also, huge congrats to my colleague @jameststroud.bsky.social! Can't wait to see what you discover in your long-term eco/evo experiment, Lizard Island!

Great detailed thread on evolution (and lizards)

Supercool 🧵 on lizards missing limbs, some ways they adapt and how this relates to our understanding of evolution. Once again, biology is more complicated

In my long career of catching anoles, it was not unusual to sometimes see lizards missing whole limbs. It was awesome to be part of this huge collaboration to study this phenomenon broadly!

👇 an interesting thread on this study, led by @jameststroud.bsky.social and emerged after long discussions about the limits of morphological performance in lizards with @jblosos.bsky.social. A beautiful example of how natural history observations generate relevant debates in evolutionary biology.

🦎THREAD: We just published something wild in @asn-amnat.bsky.social - lizards missing entire limbs not only survive, but some appear to actually thrive in the wild?! Let me tell you about the "three-legged pirate" lizards 🏴‍☠️ [Paper: www.journals.uchicago.edu/doi/10.1086/... ] (1/n)

122 cases of limb loss in lizards revealed that these these rare survivors of traumatic injuries can run just as fast, maintain healthy body weight, reproduce successfully & live surprisingly long lives. Article: www.journals.uchicago.edu/doi/10.1086/... Summary: theconversation.com/3-legged-liz...

Some fun chameleon and Anolis contributions from the Anderson Lab to this work!

Three-legged lizards across diverse species can maintain healthy body weight, reproduce, and even match or exceed the speed of fully-limbed individuals, challenging assumptions about evolutionary constraints. doi.org/g96qz6
