However, the specific nature of these mutations and the ways in which they impact fitness remain poorly understood. We exploited recent advances in genomics to predict deleterious mutations in the black grouse (Lyrurus tetrix), an iconic lekking species. Analysis of 190 whole genomes alongside comprehensive life-history data including repeated measures of behavioural, ornamental and fitness traits revealed that deleterious mutations identified through evolutionary conservation and functional prediction are associated with reduced male lifetime mating success. Both homozygous and heterozygous deleterious mutations reduce fitness, indicating that fully and partially recessive mutations contribute towards an individual’s realized mutation load. Notably, deleterious mutations in promotors have disproportionally negative fitness effects, suggesting that they impair an individual’s ability to dynamically adjust gene expression to meet context-dependent functional demands. Finally, deleterious mutations impact male mating success by reducing lek attendance rather than by altering the expression of ornamental traits, suggesting that behaviour serves as an honest indicator of genetic quality. These findings offer insights into the genetic architecture of male fitness and illuminate the complex interplay between genetic variation and phenotypic expression. Analysis of whole genomes and life-history data of male black grouse shows that deleterious mutations, especially those in promotors, reduce lifetime reproductive success.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"9 10","pages":"1924-1937"},"PeriodicalIF":13.9,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41559-025-02802-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144812933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present a spatial description of the global, bathymetric and taxonomic extent of the benthic marine class Asteroidea using a compiled dataset of ~200,000 species-level occurrence records. We used these data to produce comparisons of sea-floor richness between hemispheres and oceans. We show that species richness is significantly correlated with temperature and nutrient flux despite markedly different distributional patterns across oceans and latitudes that suggest further influence from a combination of additional geographic, taxonomic and environmental factors. The relative importance of temperature and nutrient levels also varies greatly with depth. Species richness peaks in the shallow-water tropics, closely matching sea-floor temperature variation, but at bathyal and abyssal depths it is higher at temperate latitudes, where nutrient flux levels are of greater importance. We show that richness in the deep benthos is restricted below ~1.5 °C, with this strong thermal threshold consistent among oceans irrespective of other factors. Global trends in species richness in the deep sea are poorly explored. This study uses occurrence records of Asteroidea to show that species richness in the deep benthos is restricted below ~1.5 °C but correlated with temperature and nutrient flux, despite different patterns across oceans and latitudes.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"9 10","pages":"1910-1923"},"PeriodicalIF":13.9,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41559-025-02808-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144796990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SSWD killed billions of the most susceptible species, sunflower sea stars (Pycnopodia helianthoides), initiating a trophic cascade involving unchecked urchin population growth and the widespread loss of kelp forests. Identifying the causative agent underpins the development of recovery strategies. Here we induced disease and subsequent mortality in exposure experiments using tissue extracts, coelomic fluid and effluent water from wasting sunflower sea stars, with no mortality in controls. Deep sequencing of diseased sea star coelomic fluid samples from experiments and field outbreaks revealed a dominant proportion of reads assigned to the bacterium Vibrio pectenicida. Fulfilling Koch’s postulates, V. pectenicida strain FHCF-3, cultured from the coelomic fluid of a diseased sunflower sea star, caused disease and mortality in exposed sunflower sea stars, demonstrating that it is a causative agent of SSWD. This discovery will enable recovery efforts for sea stars and the ecosystems affected by their decline by facilitating culture-based experimental research and broad-scale screening for pathogen presence and abundance in the laboratory and field. The causative agent of sea star wasting disease has been elusive. This study used genetic datasets and experimental exposures to demonstrate that a strain of the bacterium Vibrio pectenicida caused disease and mortality in sea stars.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"9 9","pages":"1739-1751"},"PeriodicalIF":13.9,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144777995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
