- Reposted by Judith A.H. SmitBreaking News 🚨: Our #bioacoustics 🔉🐬🦇lab seeks a permanent new colleague in a tenure-track assistant professor 🥷position. Excited? Then join our vibrant group of 15 researchers, postdocs and PhD students at AU who work with #marinemammal #acoustics, #conservation #physiology and #effectsofnoise!
- Reposted by Judith A.H. SmitHappy to share that our paper on the #evolution and #genomics of the most common #color polymorphism in #frogs is now out in @pnas.org! My favorite frogs even made the cover of this week’s issue! 🎉🐸🎉 Read the paper here: www.pnas.org/doi/10.1073/...
- Reposted by Judith A.H. SmitI'm looking for PhD students to join the lab starting August 2026. We study the evolution of insect chemical signals so if you're interested in evolutionary biology, chemical ecology, molecular biology, behavior, or genetics, this could be a good fit for you!

- Reposted by Judith A.H. SmitHow do light and noise pollution impact selection on sexual signals? We tested mate attraction and bat predation on túngara frogs in the field.

- Beautiful #treehoppers (Umbonia crassicornis or thorn bugs) in our garden in Panama! 😍 With a body length of ~1cm one of the biggest species around! #treehopper #membracids #insects

- Awesome study, check it out!!
- Why do treehoppers look so weird?! Our latest paper, out this week in @pnas.org, suggests a perhaps unexpected reason - static electricity ⚡ We show that treehoppers can detect the electrostatic cues of predators and that their crazy shapes may boost their electrosensitivity! doi.org/10.1073/pnas...
- Reposted by Judith A.H. SmitIn some species, the function of the treehopper's pronotum (the body part that forms the crazy structures) is intuitive - for example, there are species that look like thorns, which presumably helps them hide from predators or injure attackers. But in many species, a function is not obvious...

- Decided to become a member of @sortee.bsky.social! Excited to learn more about and be involved with open science in ecology & evolutionary biology!
- Reposted by Judith A.H. SmitA recent preprint from us. Tungara frogs use multifaceted cues to social context to guide adaptive flexibility in calling strategies. Cues involve conspecific stimulation patterns experienced between calls, and how these patterns interact with endogenous call rhythms. www.biorxiv.org/content/10.1...

[This post could not be retrieved] - Reposted by Judith A.H. SmitMy NSF PRFB on the genetics of female polymorphism in hummingbirds was terminated yesterday. I don't have much to say, I'm just sad. We've discovered so much, and could have gone so much further. If anyone else is in the same boat, esp postdocs, please reach out, it would be good to connect.
- Three different moments in the life of a treehopper (Campylenchia hastata). They look totally different after each of their five molts! #treehoppers #membracids #insects

- Found this treehopper (Calloconophora pinguis) guarding her eggs! She will later defend her hatched offspring against predators. So cool to see maternal care in insects! #treehoppers #membracids #insects
- Really cool to see a short piece out in @jexpbiol.bsky.social titled 'Picky city frogs: urban noise and light indirectly affect mate choice' highlighting our recent paper! 🐸🌃🎤 doi.org/10.1242/jeb.... Link to our paper: academic.oup.com/beheco/artic... #urbanization #behavior #evolution
- Doing some exploratory fieldwork looking for different #treehoppers, these creatures are very cool and weird and interesting!!! Found aggregations of Guayaquila (?) adults and nymphs in Santa Fe, Panamá. #insects #bugs
- Today I officially started my postdoc in Panama. I'm very excited to be studying vibrational duetting in tropical treehoppers!!!! (photo below is the office at the Smithsonian Tropical Research Institute)
