However, the paternal genetic landscape of its sub-branches coupled with its migration history has never been uncovered. In this study, 37 Y-chromosomal short tandem repeat (Y-STR) loci of three Qiang ethnic groups (N = 564) were investigated to shed light on their paternal genetic landscape. The phylogenetic reconstruction among 29 populations was conducted based on their Y-chromosomal haplotypes. The genetic affinities of the four different Qiang subgroups exhibited obviously variant when compared with Han, Yi or Tibetan in Tibetan-Yi corridor. Based on machine learning method, the predicted Y chromosome haplogroups demonstrated the predominance of O2a1 and O2a2. The haplogroup distributions were compared among 40 contemporary ethnic groups in West China and DNA samples of 214 ancient humans from 59 archaeological sites. The results supported that Wenchuan Qiang had historical links with the ancients in West Liao River (WLR) region. Moreover, intrapopulation gene flow was analysed using Migrate-n. Bidirectional migration was proved to be the most frequent model among the Qiangic populations while the unidirectional migration was only observed from Wenchuan to Li County.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 5","pages":"242046"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12092108/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144120448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider three types of network games: the majority game, the minority game and the best-shot public goods game. For any proposed Nash equilibrium, we identify the conditions and constraints of the network structure necessary to achieve that equilibrium in each game. Acceptable networks-i.e. networks that satisfy the assumed Nash equilibrium-are not unique, and their numbers grow exponentially based on the number of players and the combination of strategies. We provide mathematical relationships to calculate the exact number of networks that can create the specified Nash equilibrium in the best-shot public goods game. Additionally, in the majority and minority games, the relationships presented under special conditions specify the number of networks. We also investigate the distribution of acceptable networks as microsystems associated with the existing Nash equilibrium and their probability of occurrence. Our simulations indicate that the distribution of acceptable networks according to density follows a normal distribution, and their probability of occurrence increases. In other words, denser networks are more likely to lead to the desired Nash equilibrium.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 5","pages":"241928"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12092136/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144120508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Δ'17OBW is promising, but its relationship to organismal variables such as metabolic rate and water intake have not been validated. Here, we continuously measured oxygen influxes and effluxes of captive deer mice (Peromyscus maniculatus), and manipulated their water intake and metabolic rate. We used these oxygen flux data to predict Δ'17OBW for the mice and compared these model predictions with Δ'17OBW measured in blood plasma samples. As expected, Δ'17OBW positively correlated with drinking water intake and negatively correlated with metabolic rate. All predicted Δ'17OBW (based on measured oxygen fluxes) values differed from measured Δ'17OBW values by <30 per meg (mean absolute difference: 11 ± 9 per meg), suggesting high accuracy for this modelling approach because studies currently report a range of 300 per meg for Δ'17OBW among mammals, birds and fish.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 5","pages":"241942"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12092135/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144120667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, mathematical models integrating its social and ecological dynamics are rare. Here, we use complex adaptive systems theory to develop a model where individuals rely on labour exchange driven by reciprocity and normative reasoning that can lead to sanctions. Our results identify three emergent regimes: low-intensity swidden, sustainable high-intensity swidden that maximizes ecosystem services and harvest returns, and deforestation. We show that sustainable high-intensity swidden evolves if labour reciprocity and normative reasoning are balanced: helping behaviour should be significantly conditioned by normative reasoning to prevent over-harvesting, while reciprocity is necessary to prevent excessive sanctioning. We find that the sustainable high-intensity swidden regime is robust to changes in group size, is resilient to environmental shocks, can evolve under various models of forest ecology and is most productive for both forests and farmers when the balance of labour reciprocity and normative reasoning results in an intermediate scale of forest disturbance. Overall, we illuminate the importance of Indigenous social norms and customary practices related to swidden labour in maintaining sustainable and intensive swidden agriculture.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 5","pages":"242197"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12096101/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144128537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, musculoskeletal models used in simulation studies are typically simplified, meaning that their efficacy must first be demonstrated on living animals. Here, we evaluate a workflow for forward-dynamics simulations of maximum-effort vertical jumping, using simplified human and guineafowl models built with muscle masses from either measured data or estimated with methods previously applied to fossils. Predicted human performance was approximately 10% below experimental averages when known muscle masses were used, while the error ranged between +3 and -10% with palaeobiological methods. The simulations also correctly replicated the kinematic strategies (countermovement or squat jump) used across different starting postures. In contrast, predicted guineafowl performance was around 50-60% experimental values, irrespective of reconstruction method. Guineafowl model underperformance likely reflects simplifications related to foot mobility, muscle activation speeds and muscle fibre lengths, with the latter potentially being adaptively important to exceptional avian jumping performance. These findings emphasize that current muscle reconstruction and simulation approaches are most suited for evolutionary analyses where broad changes in body morphology and posture may significantly impact vertical jumping through pronounced qualitative differences in kinematic strategy.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 5","pages":"242109"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12092134/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144120198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, Corumbella werneri from the Tamengo Formation (Corumbá Group, Brazil) has been variously interpreted as affiliated with cnidarians or bilaterians. Using synchrotron imaging and machine learning, we analysed new specimens of C. werneri to reconstruct their original skeletal organization. Our findings reveal that Corumbella's tubes were originally conico-cylindrical. Large individuals of Corumbella, including less compacted specimens, and compression experiments with modern annelid tubes all indicate that previous reconstructions of a quadrate outline and midline features were misled by taphonomic artefacts. We also show that the wall of Corumbella is composed of a single layer of ring-shaped elements. Unlike the fourfold symmetry of scyphozoans or the complex cataphract-like structures of Cambrian bilaterians (e.g. halkieriids, tommotiids and wiwaxiids), Corumbella displays structural similarities with other late Ediacaran corumbellomorphs, such as Costatubus. These taxa exhibit a distinctive barrel-on-barrel tube construction, with modular elements stacked on each other rather than nested. Our findings redefine Corumbella's morphology and phylogenetic affinities, contributing to a broader understanding of early biomineralizing metazoans and their ecological roles in the Ediacaran biosphere.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 5","pages":"250206"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12092125/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144120502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental motion data and ground forces were input into biomechanical models to calculate joint angles and moments, then transformed into principal components and input into a feature selection pipeline. Ten main biomechanical features were identified for each limb, i.e. the pivot limb and the swing limb, that could discriminate between symptomatic and control groups with p < 0.05. In symptomatic individuals, the main features were as follows: pivot limb: smaller hip flexion and knee extension angles, delayed initiation of hip flexion and increased ankle dorsiflexion moment; swing limb: reduced hip flexion moment, increased hip internal rotation moment, delayed hip adduction and knee extension moments, and reduced ankle dorsiflexion angle. The largest group differences occurred during the transitions from step-down to pivot, and pivot to step-forward, supporting a potential role for multi-phase and/or multi-planar tasks when assessing biomechanical impairments due to hip/groin pain.

However, the adoption of open science practices may depend on the fit between researchers' perceptions of open science and the social dynamics of their field. For example, if researchers understand open science as primarily a means of cooperating with other researchers, its adoption may be faster and more effective among researchers who see their field as less competitive and less hierarchical. The present studies operationalize open science attitudes as plans to publicly share manuscripts/preprints, code, stimuli/instruments and data, as well as participants' perceptions of the importance of these practices. In Study 1, researchers perceived the social dynamics of their field (competition and hierarchy) as distinct from the traits of individuals in their field (warmth and competence). In Study 2, neither researchers' perceptions of social dynamics, nor their view of open science as motivated by cooperation, predicted their attitudes to open science practices. However, attitudes about open science were generally very positive among researchers who opt-in to a study about open science, limiting the variance to be explained. Moreover, people's self-reported motivations for sharing manuscripts and materials differed from their perceptions of why others share manuscripts and materials.

This is because asexual parthenogenesis is a more efficient mode of reproduction, and all-else-being-equal, should predominate over sex. Asexual reproduction is not without its disadvantages though, the lack of genetic recombination can render parthenogenetic lineages vulnerable to extinction under environmental change, or compromise fitness owing to the buildup of deleterious recessive mutations. Facultative sex, where individuals retain the ability to reproduce sexually and asexually, has been touted as 'the best of both worlds', providing the long-term genetic benefits of sex without the short-term costs. In this study, I found that parthenogenetic females of the sexually polymorphic aphid parasitoid Lysiphlebus fabarum readily engage in facultative sex, but facultative sex was not the 'best of both worlds' owing to elevated rates of reproductive failure compared to obligate sex and parthenogenesis. By contrast, obligately sexual females had increased fecundity compared to asexual females. In L. fabarum, it seems that all is not equal; the fecundity advantage that obligate sex provides, along with the costs of occasional facultative sex by asexuals must be factored in when attempting to understand why and how different reproductive modes coexist in nature.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 5","pages":"242162"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12092129/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144120452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
