This provides a unique opportunity to assess the potential for markets to benefit biodiversity. We assessed the extent to which projects under the ACCU scheme overlap potential threatened species habitat, compared that to overlap afforded by protected areas, and compared the ability of different project types to deliver potential benefits to species most impacted by habitat loss. Projects are primarily located in low-cost, marginal arid lands, a pattern that reflects that of the protected area estate. Projects are smaller and fewer in number in more productive lands close to human populations. These lands also overlap most threatened species habitat, hence those species most in need of habitat restoration are the least likely to have their habitat restored under the ACCU scheme. Projects, however, do overlap the geographic range of 32% of the 1,660 threatened species assessed, including for 275 species with <17% of their range in protected areas. Biodiversity markets must incentivize actions in areas of high biodiversity value underpinned by regulations that align with national priorities for biodiversity conservation. An assessment of the Australian carbon credit units scheme finds that most current projects under the scheme overlap the habitats of few threatened species. The findings generate lessons for the planned development of a national biodiversity market based on the ACCU scheme.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"9 1","pages":"134-141"},"PeriodicalIF":13.9,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637053","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}

Here, to better understand this dual role of environment in the production and selection of phenotypic variation, we determined genotype–phenotype–fitness relationships for mutant strains of Saccharomyces cerevisiae in four environments. Specifically, we measured how promoter mutations of the metabolic gene TDH3 modified expression level and affected growth for four different carbon sources. In each environment, we observed a clear relationship between TDH3 expression level and fitness, but this relationship differed among environments. Mutations with similar effects on expression in different environments often had different effects on fitness and vice versa. Such environment-specific relationships between phenotype and fitness can shape the evolution of phenotypic plasticity. We also found that mutations disrupting binding sites for transcription factors had more variable effects on expression among environments than those disrupting the TATA box, which is part of the core promoter. However, mutations with the most environmentally variable effects on fitness were located in the TATA box, because of both the lack of plasticity of TATA box mutations and environment-specific fitness functions. This observation suggests that mutations affecting different molecular mechanisms contribute unequally to regulatory sequence evolution in changing environments. Measuring how mutations in the promoter of a metabolic gene modified its expression level and affected growth of Saccharomyces cerevisiae in four environments, the authors show that the effects of mutations on gene expression and the relationships between expression levels and fitness vary among environments.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"8 12","pages":"2184-2194"},"PeriodicalIF":13.9,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41559-024-02582-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601079","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}

How the increased frequency and intensity of warm extremes affect NEE variations remains unclear. Here, we combined multiple NEE datasets from atmospheric CO2 inversions, Earth system models, eddy-covariance data-driven methods and climate datasets to show that the terrestrial carbon sequestration capacity is weakened during warm extreme occurrences over the past 40 years, primarily contributed by tropical regions (81% ± 48%). The underlying mechanism can be rooted in the overwhelmingly decreased trend of gross primary productivity compared with terrestrial ecosystem respiration. Additionally, the weakened terrestrial carbon sequestration capacity is mainly driven by the transition from temperature or soil moisture control to vapour pressure deficit control, which is associated with the increasing intensity of warm extremes. Our findings suggest that warm extremes threaten the global carbon sequestration function of terrestrial ecosystems. Therefore, more attention should be given to the evolution of the increasing intensity of warm extremes in future climate projections. Extreme weather events are becoming more frequent and may have disproportionate effects on carbon cycling. Here, the authors quantify the impact of warm extreme occurrences on terrestrial carbon sequestration capacity over the past 40 years.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"9 1","pages":"124-133"},"PeriodicalIF":13.9,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597545","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}
