Genetic erosion and projected habitat loss in the protected Alpine moth Actias isabellae galliaegloria (Lepidoptera: Saturniidae) https://www.biorxiv.org/content/10.64898/2026.02.19.706775v1

Project Psyche: reference genomes for all Lepidoptera in Europe Project Psyche is a transnational initiative to generate and study chromosome-level reference genomes of all ~11 000 species of Lepidoptera (butterflies and moths) found in Europe. Here, we describe t...

(1/5)Thrilled to announce our paper on #ProjectPsyche is out! 🦋We describe how we’ve generated 1000+ high-quality genomes for European Lepidoptera, providing an unprecedented resource for biodiversity, conservation, and evolutionary research.

Conservation strategy insights for three protected Phengaris butterflies combining population genomics and landscape analyses Phengaris butterflies depend on specific wetland habitats, host plants and ant species, making them highly vulnerable and protected across Europe. Population genomics and resistance mapping combined.....

Capturing diversity below the species level using HyRAD : a nuclear-DNA enrichment-based capture method (HyRAD) applied to environmental DNA. Post provided by Stéphanie Manel. Why use HyRAD for eDNA capture? Traditional population genetics approaches require sampling tissue from individuals, which is problematic in aquatic environments w…
