📢 Paper out! We show that the oak leaf miner outbreak in Sweden is not caused by Acrocercops brongniardella, but by a cryptic species, A. andreneli — both sharing an entire parasitoid community.

A cryptic moth species drives major outbreak dynamics on oak without escaping its natural enemies

Global forest ecosystems are experiencing increasingly frequent and severe insect outbreaks, driven by complex interactions among climate change, land…

Stigmella sp.! Imposible (o casi) de criar en laboratorio, a diferencia de otros minadores del roble, que son ideales para estudios de especies multivoltinas.

Habrá más abundancia de arañas en árboles donde hay mas bellotas con melazo?

Alvaro Gaytan @agaytan.bsky.social · Jul 7

Me encantó la idea de la transmisión del microbioma entre la bellota y el insecto. Incluso podría tener una huella en las arañas como depredadoras de los comedores de melazo.

I will happily spend the summer at @eawag.bsky.social 🇨🇭. Not really in aquatic research but in multilayer network analyses with my terrestrial ecology stuff.

Pues te dejo una teoría rocambolesca a ver si ilumina algo (jajaja): por la noche baja la temperatura y los ungulados se mueven más buscando recursos de encina en encina... si esos escarabajos son del grupo que yo digo, son coprófagos.

🚨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.

Sí, genial! Más aún este año, que estoy escapando del calor con un par de congresos en el norte y una estancia en Lucerna. Un abrazo, Fernando!

Loving natural history as we do makes it difficult for us to feel lost, but keeps us in constant learning. But I'm agree... is not possible to attend many histories simultaneously.

Clouds darkening over NOAA research. We are slated for elimination in next years budget. Astonishing loss to the nation and the world if it happens.

BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency.

Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.
