Soaring Systematics: an evaluation of biogeography and flight behavior in dragonflies and damselflies (Insecta: Odonata) using phylogenomics Abstract. Dragonflies and damselflies (Insecta: Odonata) are descended from what were most likely the first winged animals, which flew ∼320 million years a

Years of fun collaboration, led by Dr. Lacie Newton together with our #GEODE #NSF #DRAGONFLY #phylogeny #systematics team, Seth Bybee, John Abbott, Rob Guralnick, Vincent Kalkman, and rest of #GEODE community!

GhostParser: A highly scalable phylogenomic approach for the identification of ghost introgression A growing body of empirical research shows that interspecific gene flow is a widespread biological force that shapes evolutionary histories across the Tree of Life. Computational approaches designed t...

My very first post on here.
I am stoked to share lab's latest paper led by @ethantolman.bsky.social. Ethan developed a highly scalable pipeline to differentiate between various gene flow models, including ghost introgression in phylogenomic datasets. Check it out! www.biorxiv.org/content/10.1...

Meet the Beautiful Dragonfly That Thrives in Your Pollution

Excited to have this #entomology #dragonfly paper out! Congratulations to @ethantolman.bsky.social Ellie Gamett and team! bmcecolevol.biomedcentral.com/articles/10....

@gracie-castillo.bsky.social, @harrisonpardue.bsky.social, @eredman3.bsky.social and Liam Williams found alarmingly high levels of inbreeding in Trout, and discuss what this means for the Odonata they live with!

@isaaclevesque.bsky.social @jiaweiz.bsky.social, Sam Gallafent, Randy Li, and Atharva Tripathi found that insects sampled from the same habitat have responded differently to anthropogenic change and past climate change!

Maleah Wei and @bengallafent.bsky.social shared an awesome talk about urban adaptation and migration in the blue dasher dragonfly, as well as the importance of community science engagement, with their advisor Dick Jordan!

Thanks to @jessicalwarelab.bsky.social @chrisdbeatty.bsky.social and @annaeichert.bsky.social for helping with the research projects!
