Plants in these environments have evolved adaptive strategies to enhance water-use efficiency and ensure reproductive success, two of which are annuality and C4 photosynthesis. However, life history variation is rarely included in large-scale studies of plant diversity, and the extent to which these traits coevolve and are jointly selected for is not known. To address this, we used Pagel's models of independent and correlated evolution for over 4000 species of grasses (Poaceae), while accounting for evolutionary rate heterogeneity and potential type I statistical errors. We found that there are more C4 than C3 annuals and that C4 origins predate evolution of annuality, but no support for correlated evolution between the two traits. Our results indicate that any habitat or trait similarities (e.g. small seeds, fast growth) between annuals and C4 species reflect independent adaptations to similar environmental conditions or are contingent on the two traits themselves, rather than the result of evolutionary or functional links between them. Our results further highlight the importance of appropriate null model specification for testing evolutionary hypotheses across large, old clades.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"22 4","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147687972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined how contest skill influences contest success, costs and whether skilful behaviour enhances welfare. We measured skill across three domains: accuracy, appropriateness (selecting suitable agonistic tactics when the optimal choice varies) and efficiency, alongside vigour, sex and body weight. Skill was weakly correlated across domains. Winners were heavier relative to their opponent, displayed greater vigour and were more skilful at blocking, but other skill measures did not predict contest win/loss outcome. Appropriate blocking by winners reduced the number of lesions received by reducing exposure to attacks, suggesting it can both reduce costs and improve competitive success, with potential welfare benefits. Losers received more lesions when they adopted appropriate postures after submission; however, this unambiguous submission may have resulted from more costly contests. For winners, being heavy relative to the opponent tended to reduce skin lesions received, but otherwise, having a weight advantage did not reduce contest costs. Fighting with increased vigour led to a considerable increase in contest costs, particularly in losers. Compared to other resource-holding potential traits, skill has moderate effects on winning and injuries but nevertheless modulated energetic costs of fighting.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"22 4","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147687938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The duration of the nestling period (DNP) depends on the hatching synchrony of eggs and the speed at which chicks acquire these abilities but may be indirectly affected by parental behaviour and temporal variations in temperature and predation. We assessed the effects of incubation strategy (bi- or uniparental), hatching start time, incubation initiation date and predation risk on the DNP in Arctic-breeding sandpipers. We found that the DNP was longer in biparental species (29.75 ± 8.95 h) compared with uniparental ones (25.82 ± 6.87 h) and was extended in nests where chicks began hatching during the colder 'night' hours. No effect of incubation initiation date or predation pressure was found on the DNP. We suggest that parental investment strategies and constraints related to circadian variations in temperature in chicks drive the DNP in Arctic-breeding sandpipers. These results help us better understand how different species may exhibit different behavioural responses during nesting to impending climate change.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"22 4","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147688020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although progress has been made focusing on polymorphisms at major-effect genes, our understanding of how genome background modulates phenotypic expression remains limited. To address this, we focus on two female postmating responses-egg laying and remating rate, both primarily triggered by sex peptide (SP) transfer from males-across different genome backgrounds and yeast environments. Using 10 Drosophila melanogaster Drosophila Genetic Reference Panel lines carrying an identical SP allele, we found significant effects of both genome background and yeast on egg laying and remating behaviour. SP expression analysis revealed no significant differences among lines, suggesting that the observed phenotypic variation is not driven by transcriptional regulation of the focal gene. However, a genome-wide association analysis of remating under yeast supplementation identified genetic variants non-randomly distributed across chromosomes and implicated potential effectors to this complex trait. Together, our results highlight how genome background can contribute substantially to phenotypic variation that is commonly ascribed to allelic differences at major regulators of reproductive success.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"22 4","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147632377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These challenges can intersect when molecular tools uncover hidden diversity and inadvertently confound efforts to trace species origins. In marine systems, environmental DNA (eDNA) has transformed biodiversity monitoring, but reliance on short, single-locus markers makes it vulnerable to false-positive detections of cryptic sibling species with markers lacking sufficient taxonomic resolution. Extending previous investigations into the occurrence and spread of Chondria tumulosa, we conducted eDNA screening in multiple island regions to evaluate possible range connectivity. A quantitative polymerase chain reaction assay developed from a Northwestern Hawaiian Islands barcode produced a novel eDNA detection at Majuro in the Marshall Islands. However, subsequent multilocus sequencing (cytochrome c oxidase subunit I, ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit, 18S small subunit ribosomal RNA, Universal Plastid Amplicon) of collected material revealed consistent sequence divergence, suggesting independently evolving lineages. Our findings suggest that the Hawaiian C. tumulosa and the Majuro lineage are sibling taxa with a broader Pacific distribution, shaped by historical allopatry and possible human-mediated dispersal. This case highlights the need to confirm eDNA matches using informative multilocus barcoding regions and emphasizes the need to integrate genetic, morphological and ecological data to resolve the identity and origins of cryptogenic taxa.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"22 4","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147632489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of approximately 1350 described nemertean species, only approximately 35 are known from below 500 m, and only six species are genetically confirmed as eurybathic. In 2022, we reported the Costa Rican material but withheld a species description because its cytochrome c oxidase subunit I (COI) closely matched that of T. lutescens. Here, we re-examined serial sections of the holotype plus its COI vouchers and generated mitochondrial genomes and hundreds of single-copy nuclear orthologues from one Costa Rican and one Swedish specimen using low-coverage whole-genome sequencing. Morphological and genome-scale comparisons support a single species spanning shallow to bathyal habitats across both the Atlantic and Pacific. This establishes T. lutescens as the first confirmed eurybathic palaeonemertean, exhibiting the widest geographic and bathymetric range among nemerteans and an exceptional range even among benthic marine invertebrates. Because one population inhabits a deep-sea seep, anthropogenic dispersal is unlikely.
