@bkoskella @JohnStinchcombe @ME_Frederickson Thanks Britt! Would love to hear your thoughts 😀

[Tia Harrison 🌿🦠 @tialeneharrison]

New preprint on my molecular evolution work with @JohnStinchcombe and @ME_Frederickson! Inspired by work in parasite literature, we looked for evidence of increased rates of molecular evolution in mutualistic interactions. What did we find?

Elevated rates of molecular evolution genome-wide in mutualist legumes and rhizobia https://t.co/FPPZpwvKtA #biorxiv_evobio

[Tia Harrison 🌿🦠 @tialeneharrison]

Although we find high rates of molecular evolution across mutualist genomes, symbiosis genes do not show evidence of ongoing coevolution. We would be happy to hear your feedback and ideas on our work!

[Tia Harrison 🌿🦠 @tialeneharrison]

We observed the same pattern in bacteria genomes. Genome wide, nodulating bacteria had higher dN/dS ratios compared to non-symbiotic bacteria.

I'm going to be presenting at #TAGC24 tomorrow at 12:00 in the Plant Evolutionary Genetics session. Come check it out if you're interested in plant ecological genetics, GxE for complex traits, or if you would like to hear about some snowy Arabidopsis!

I am thrilled to share our work on ants from the #Galapagos! By combining fieldwork and museum specimens, we studied more than 382,000 introduced and endemic ants in the islands. Thanks to @EspochRio, @DarwinFound, @Galapagospark and @BelgianNatural! https://t.co/heklundNep

Surprisingly, we saw a decrease in diversity and increase in abundance of anaerobic taxa in treatments with high concentrations of organic de-icers. The drastic shift in the bacterial community suggests that organic de-icers may not be as “eco-friendly” as initially anticipated!

[Tia Harrison 🌿🦠 @tialeneharrison]

The impacts of traditional, inorganic, and organic de-icers were tested on lake water bacterial community assembly in a mesocosm experiment at @QUBioStation. After 6 weeks, the 16S rRNA locus was sequenced in bacterial community samples.

Our team combines perspectives from molecular biologists, microbiologists, and ecologists including @troymartinlimno, Collin Juurakko, @ShelleyArnott, and Virginia Walker

[Tia Harrison 🌿🦠 @tialeneharrison]

Do you use salt on your icy driveway? There are lots of de-icer options currently available. Before you make your choice, check out this work I had the opportunity to contribute to as part of a collaborative team at @QueensUBio https://t.co/1AzlycyWBe

One of my PhD projects with @JohnStinchcombe and @ME_Frederickson is now published in Molecular Ecology! We uncovered a latitudinal diversity gradient in non-rhizobia microbes associated with C. nictitans plants but not in rhizobia. https://t.co/tUddGhXuvf

[Julia Kreiner @jmkreiner]

I too am recruiting graduate students, postdocs, and a lab technician for my group at UChicago, starting fall 2024! We will be doing exciting work to uncover the limits of plant adaptation in changing environments.

Twinning at #SMBE2023 with @maddie_e_james 😂

[Tia Harrison 🌿🦠 @tialeneharrison]

Tonight (July 25) I will be presenting my poster #724 in the San Paolo Cloisters for #SMBE2023! Come by to see how symbiosis with rhizobia impacts rates of molecular evolution in legumes

[Tia Harrison 🌿🦠 @tialeneharrison]

My microbes and I have moved! I officially started as a postdoc in the @George_diCenzo lab @QueensUBio this month. Excited to be continuing my work on legume-rhizobium interactions while learning some new molecular biology techniques 😀
