We know that the role of nocturnal moths as pollinators has been greatly underestimated in Europe, but this impressive new study shows that tiger moths (Arctiinae) are important generalist pollinators in a lowland rainforest in Ecuador #teammoth 🌎

Blüten, Bestäuber und ihre Bakterien – eine Dreiecksbeziehung - BIOspektrum The plant-microbe-pollinator triangle represents a mutualistic tripartite interaction network among plants, microbes, and insects. Microbes do not only support pollinator health but influence pollination success directly by altering the scent of nectar. Pollinators, in turn, can serve as microbial vectors, and transfer microbes between flowers and across species. Understanding these complex interaction networks is crucial to sustain ecosystem service by wild pollinators for future generations.

Can´t dm you. So I put it here.

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.

🚨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.

(1/4) 🦋 From May 12–16, 21 researchers from across Europe met in Montpellier for the 1st LepEU Workshop, coordinated under the COST Action @10klepgenomes.bsky.social

The goal: build a roadmap for collaborative butterfly and moth #PopulationGenomics to advance biodiversity research & conservation 👇

That was indeed a net-working event! 😅🦋 #LepEU

The European Lepidoptera Population Genomics Consortium is a group focused on unveiling patterns of differentiation and local adaptation in butterfly and moth populations across Europe 🦋🌍

First #LepEU meeting in Montpellier was a great success. Thanks to all organizers #CNRS #COST10KLepGenomes for making this happen

Two great #postdoc opportunities! #insect #microbe #mutualism

Only few butterflies around... but a Halictus was very cooperative.
