Great to have our caddisfly silk review now included in an issue in Trends in Genetics. And, I might be biased, but that sure is a beautiful cover ;)!

The June issue is live!

Two Opinion articles challenge the way we think about the genomic code, and Reviews cover topics ranging from human handedness to caddisfly silk (the latter of which is featured on the cover, courtesy of @paulbfrandsen.bsky.social).

In this issue of Trends in Genetics, Frandsen and colleagues review the current state of caddisfly silk genetics research and outline future directions aimed at linking the genotype and phenotype of this extraordinary biomaterial.

Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution.

🚨Postdoc opportunity🚨: LepEU postdoc: comparative population genomics of European scale adaptation in butterflies

2 year, full-time PD in my group, Stockholm Univ.

Applications assed on rolling basis, deadline: 23 August 2025. Planned start 1 Oct.

Details:
christopherwheatlab.wordpress.com
The aim of this proposal is to place population genomic insights into a comparative framework to gain fundamental insights into the determinants of evolutionary outcomes. The project will work within LepEU, the European Lepidopteran Population Genomics Consortium (https://lepeu.github.io/). LepEU provides access to field samples from European populations of diverse species. Chromosome-scale reference genomes are provided by Project Psyche (https://www.projectpsyche.org/). Networking during the postdoc will be facilitated by participation in the 10kLepGenomes COST Action (https://10klepgenomes.eu/). Existing datasets await analysis, while additional samples need DNA extraction and submission for sequencing. Functional validation capability (CRISPR/Cas9 gene manipulations) is also available to test emergent hypotheses of allele-to-phenotype impacts. Personal research interests of the postdoc will be important to determine the exact project, as the project has a generous sequencing budget. The successful applicant should have a PhD (obtained within 6 years of the application deadline) in a suitable subject area, such as evolutionary biology or population genomics. A strong interest in population genomics, local adaptation, comparative analyses, and experience working with genomic-scale data is essential. The candidate must have a documented publication record demonstrating relevant skills. Experience working with bioinformatic pipelines (e.g., Snakemake), or working with butterflies is welcome but not essential. The net salary is 28,000 SEK/month (~2,430 Euro, not subject to Swedish income tax) and comes directly from the Carl-Trygger Foundation stipend, which is paid out directly to the postdoc. Only PhD candidates acquired outside of the host department can apply. Currently, the lab of Prof. Wheat consists of 3 postdoctoral researchers, while the Dept. of Zoology provides a vibrant and excellent research environment of active, dynamic researchers. Applications should include: i) a succinct description of research interests and experience, detailing your contribution to any relevant publications (max 1 page), ii) why you are the ideal candidate for this position in the lab (max 1 page); iii) a CV including a list of publications, and iv) the name and contact information of two personal references. Applications will be reviewed on a rolling basis with a deadline of 23 August 2025. The project is planned to start on 1 October, but flexibility in the starting date can be provided for a suitable candidate. Please contact Prof. Wheat for additional information.

Phylogeny and placement of two unique case-making caddisflies, Limnocentropus and Phryganopsyche. The cases of both Limnocentropus and Phrgyanopsyche are illustrated, showing the characteristic stalk on Limnocentropus cases and the "floppiness" of the Phryganopsyche case.
