Its whole-genome resequencing strategy takes advantage of the growing availability of reference genomes for Lepidoptera. LepEU supports scalable, standardized sampling and sequencing to quantify genetic diversity and population resilience. These data will allow addressing long-standing questions about geographic patterns of biodiversity in this iconic clade for evolutionary ecology, while also filling critical gaps in biodiversity monitoring and conservation. The consortium's first in-person workshop was held in Montpellier (France) in 2025 and was supported by the COST Action 10kLepGenomes. It gathered 23 researchers from 10 countries, including experts in Lepidoptera ecology, evolution, and population genomics. Building on 2 years of video conferencing, the workshop enabled participants to draw a roadmap for trans-continental standardized sampling, isolate DNA of specimens collected during 2024, outline key research questions for LepEU, and discuss an outreach strategy to engage additional stakeholders. LepEU is coordinating with other international networks and consortia to develop a collaborative platform for tracking European lepidopteran biodiversity and evolution. Looking ahead, LepEU is focused on training and mentoring the next generation of scientists, empowering them to integrate genomic analyses with phenotypic and ecological data to address ecological, evolutionary, and conservation questions.</p>","PeriodicalId":168,"journal":{"name":"Evolutionary Applications","volume":"19 ","pages":"e70246"},"PeriodicalIF":3.2,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13161756/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147925051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs comparative transcriptomic and genomic analyses to elucidate the molecular mechanisms underlying crustacean responses to cold stress across five economically significant species: <i>Litopenaeus vannamei</i>, <i>Penaeus indicus</i>, <i>Eriocheir sinensis</i>, <i>Cherax quadricarinatus</i>, and <i>Macrobrachium rosenbergii</i>. We identified 4711 conserved orthogroups and analyzed differential gene expression under low-temperature conditions. Results revealed species-specific responses, with 25 orthogroups shared across all five species and 113 orthogroups common to at least four species. Functional enrichment highlighted pathways such as oxidation-reduction, hormone metabolism, immune regulation, and spliceosomes. Key genes, including <i>EcKL</i>, <i>CYP2W1</i>, <i>HSPA5</i>, and <i>SLCs</i>, were implicated in signaling, metabolic, immunological, and developmental adaptations. Phylogenetic analysis was used to trace the evolutionary origins of stress-responsive genes, enabling the identification of both ancient conserved genes and lineage-specific genes. The results indicated that \"younger\" genes tend to exhibit greater transcriptional plasticity than ancient conserved genes. These findings provide critical insights into shared and species-specific low-temperature adaptation mechanisms, offering a foundation for breeding cold-tolerant crustacea strains to enhance aquaculture resilience.</p>","PeriodicalId":168,"journal":{"name":"Evolutionary Applications","volume":"19 ","pages":"e70254"},"PeriodicalIF":3.2,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13163145/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147925059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is currently assumed to represent a single biological population. In coastal waters, both in Northern Norway and down to mid-Norway during the spawning season, NEAC overlaps with another cod ecotype, the conspecific coastal cod (CC), which is managed as a separate stock. Here, we analysed otoliths and conducted genotyping of 3900 cod to investigate population structure and potential ecotype mixtures in the Barents Sea. The annual surveys cover both the spawning and feeding areas of the NEAC stock with the purpose of collecting data for the annual stock assessment. While classification of individual cod to population-of-origin with the genetic markers currently available remains challenging, we-for the first time-infer the presence of CC and potential NEAC × CC hybrids also far offshore in the Barents Sea. Moreover, the CC were not homogenously distributed in the Barents Sea, but were higher in the west (including Svalbard) and in the far east, as well as near the Norwegian coast. Most of these putatively identified CC fish carried NEAC-type otoliths. Thus, cod otolith type seems a poor indicator of genetic ancestry and instead reflects environmental conditions. Many questions remain on the temporal stability of the NEAC and CC mixing in the Barents Sea, and not least, the management implications of such stock mixing. More generally, further studies are needed on the connection between within-species genetic differences and the implications of such differences for stock dynamics in a management context.</p>","PeriodicalId":168,"journal":{"name":"Evolutionary Applications","volume":"19 ","pages":"e70250"},"PeriodicalIF":3.2,"publicationDate":"2026-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13158372/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147925048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
