You ❤️ Science

You hate writing papers and dealing with reviewers…

It does not need to be like this.

GBE | The Genome Sequence of the Hemlock Woolly Adelgid, Adelges tsugae Annand 1924

@bryanbrunet.bsky.social @nphavill.bsky.social et al. present the genome of the hemlock woolly adelgid, one of eastern North America's most destructive and invasive forest pests. The 216 Mbp genome is highly complete (97.7% BUSCO).

How the yellow fever mosquito conquered the world Aedes aegypti further adapted to life around humans when it arrived in the Americas, study of hundreds of mosquito genomes reveals

The invasive form of Ae. #aegypti mosquito evolved within the Americas, after arriving from Africa ~320 ya. Our most recent paper is out @science.org. Years of work with collaborators all around led by J. Crawford! Great resource for the Vector Research community!.

Interested in joining our lab (dunnlab.org) as a postdoc to work on siphonophores, processes that structure diversity in the open ocean, or natural history? If so, please reach out to discuss a nomination for the Donnelley Postdoctoral Fellowship - yibs.yale.edu/donnelley-fe...

Join us! The Division of Invertebrate Zoology at the American Museum of Natural History is hiring a curatorial associate! For more information : careers.amnh.org/postings/4529

More creative and fun. Yay, drift!

I hope to take a PhD student in 2026 to study siphonophores. Please reach out if you are interested in applying this fall. For examples of recent lab projects see www.sciencedirect.com/science/arti... and academic.oup.com/gbe/article/...

Unusual Galls Trigger National Survey of Adelgids and Their Predators in Bhutan Forests When aphid-like insects appeared in Bhutan forests, local researchers collaborated with USDA Forest Service experts to identify species, including four new to science.

Thank you, Entomology Today @entsocamerica.bsky.social, for covering our work on adelgids of Bhutan. If we want to prevent #bioinvasions, we need to know what’s out there. Also, adelgids are super cool insects 😁

I have created a feed "plant insect ecology" for posts on the biology, ecology, evolution, & natural history of plants & insects... to post, simply include #plant-insect. Please post images, opportunities, academic articles w/ links, etc.

DM w/ suggestions, it will take some days to optimize

We put together a fact sheet for #Aedes #aegypti. You can access the corrected proof from the link below.

It’s going to be a while before it’s ready, but it’s highest on my list of priorities!

😁 The 2016 paper that Chris cites above is by me and colleagues. Working on an update with new info and updated methods.
