Despite the well-recognized shifts in selective pressures accompanying transitions among environments, the conditions driving innovation and the consequences for life-history evolution remain outstanding questions. Here we compare the traits of vertebrates that occupy aquatic or terrestrial environments as juveniles to infer shifts in evolutionary constraints that explain differences in their life-history traits and thus their fundamental demographic rates. Our results emphasize the reduced potential for life-history diversification on land, especially that of reproductive strategies, which limits the scope of viable life-history strategies. Moreover, our study reveals differences between the evolution of viviparity in aquatic and terrestrial realms. Transitions from egg laying to live birth represent a major shift across life-history space for aquatic organisms, whereas terrestrial egg-laying organisms evolve live birth without drastic changes in life-history strategy. Whilst trade-offs in the allocation of resources place fundamental constraints on the way life histories can vary, ecological setting influences the position of species within the viable phenotypic space available for adaptive evolution.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"52 1","pages":""},"PeriodicalIF":16.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143598774","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}

The evolution of background matching in camouflaged phenotypes partly depends on the genetics of the camouflage trait, but this has received little attention in plants. Here we clarify the genetic pathway underlying the grey-leaved morph of fumewort, Corydalis hemidicentra, of the Qinghai-Tibet Plateau that by being camouflaged escapes herbivory from caterpillars of host-specialized Parnassius butterflies. Field experiments show that camouflaged grey leaves matching the surrounding scree habitat experience reduced oviposition by female butterflies and herbivory by caterpillars, resulting in higher fruit set than that achieved by green-leaved plants. The defence is entirely visual. Multi-omics data and functional validation reveal that a 254-bp-inserted transposon causes anthocyanin accumulation in leaves, giving them a rock-like grey colour. Demographic analyses of plant and butterfly effective population sizes over the past 500 years indicate that plant populations have been more stable at sites with camouflage than at sites with only green-leaved plants. In the recent past, populations of Parnassius butterflies have declined at sites with camouflaged plants. These findings provide insights into the genetics of a plant camouflage trait and its potential role in the rapidly changing dynamics of plant–herbivore interactions.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"8 1","pages":""},"PeriodicalIF":16.8,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583021","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}

The law recognizes customary rights, assures compensation and resettlement for expropriated people, and guarantees the rights of Mozambicans to land and natural resources, while promoting sustainable and profitable investments1,2. However, since 2017, the World Bank and the US Agency for International Development (USAID) have been pushing for the Mozambican government to revise this law with the aim of promoting a more ‘business friendly’ form of land governance. The government has collaborated in the revision process, but these proposals have been refuted by Mozambican civil society organizations1. Although it remains uncertain whether this issue will be prioritized on the agenda of the new legislative body inaugurated in January 2025, the revised land law proposal can be brought to discussion by members of parliament at any point. The proposed revision will seriously risk rural livelihoods, the environmental sustainability that is closely connected to them, and the country’s biodiversity.Investments in large-scale extractive industries, forestry and industrial agriculture have intensified over recent decades in Mozambique, which has transformed the country into an extractive economy3. Numerous communities have been displaced by this development, but demands for compensation under the land law have been ignored. The intensifying flow of investments has stirred up serious conflicts, particularly in the northern part of the country4. According to the government, the proposed revision aims to solve such land conflicts.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"30 1","pages":""},"PeriodicalIF":16.8,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143569811","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}

Climate change is intensifying disturbances, posing risks to ecosystem services. To assess those risks, we develop a flexible, functional trait-based approach to quantify ecological, ecosystem service and economic impacts from disturbance regimes. Our broadly applicable approach integrates knowledge from disturbance ecology and ecosystem service valuation, and we highlight the pitfalls of using either perspective in isolation. We demonstrate our approach by quantifying impacts to timber and recreational enjoyment from extreme windstorms in a midlatitude forest. While we predict large potential losses to these services under historical and future disturbance regimes, common ecological metrics of compositional and biomass stability are inadequate for predicting these impacts. We then provide a roadmap for applying our approach across different social-ecological systems, illustrating the approach for crop pollination, flood hazard mitigation and cultural values from coral reefs—which all face intensifying disturbances. This study highlights and provides tools to address the pressing need to consider disturbances in future ecosystem service assessments. A generalizable, functional-trait-based approach for quantifying the effects of disturbances to ecosystem services and economic outcomes, including under climate change, highlights the need for incorporating disturbances in ecosystem services assessments.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"9 3","pages":"436-447"},"PeriodicalIF":13.9,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545994","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}

Current leading hypotheses propose that a symbiosis between an asgardarchaeal host cell and an alphaproteobacterial endosymbiont represented a crucial step in eukaryotic origin and that metabolic cross-feeding between the partners provided the basis for their subsequent evolutionary integration. A major unanswered question is whether the metabolism of modern eukaryotes bears any vestige of this ancestral syntrophy. Here we systematically analyse the evolutionary origins of the eukaryotic gene repertoires mediating central carbon metabolism. Our phylogenetic and sequence analyses reveal that this gene repertoire is chimeric, with ancestral contributions from Asgardarchaeota and Alphaproteobacteria operating predominantly in glycolysis and the tricarboxylic acid cycle, respectively. Our analyses also reveal the extent to which this ancestral metabolic interplay has been remodelled via gene loss, transfer and subcellular retargeting in the >2 billion years since the origin of eukaryotic cells, and we identify genetic contributions from other prokaryotic sources in addition to the asgardarchaeal host and alphaproteobacterial endosymbiont. Our work demonstrates that, in contrast to previous assumptions, modern eukaryotic metabolism preserves information about the nature of the original asgardarchaeal–alphaproteobacterial interactions and supports syntrophy scenarios for the origin of the eukaryotic cell.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"46 1","pages":""},"PeriodicalIF":16.8,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532594","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}
