Day 2 of the #GuardIAS meeting was all about our 11 case studies!

Great to see the nitty-gritty of using eDNA & drones for detection, modelling population spread, and launching new citizen science projects.

Also got a preview of upcoming online events from at @invasivesnet.bsky.social.

Christopher Wheat @chriswheat.bsky.social · Jun 22

🚨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.
