Although each female can reproduce both sexually (producing sons and daughters from fertilized eggs) and asexually (typically producing only daughters from unfertilized eggs), these animals often form distinct sexual and asexual populations. We hypothesized that asexual populations are maintained through female resistance as well as the decay of male traits. We tested this via experimental crosses between individuals descended from multiple natural sexual and asexual populations of the facultatively parthenogenic stick-insect Megacrania batesii. We found that male-paired females descended from asexual populations produced strongly female-biased offspring sex-ratios resulting from reduced fertilization rates. This effect was not driven by incompatibility between diverged genotypes but, rather, by both genotypic and maternal effects on fertilization rate. Furthermore, when females from asexual populations mated and produced sons, those sons had poor fertilization success when paired with resistant females, consistent with male trait decay. Our results suggest that resistance to fertilization resulting from both maternal and genotypic effects, along with male sexual trait decay, can hinder the invasion of asexual populations by males. Sexual conflict could thus play a role in the establishment and maintenance of asexual populations.</p>","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142876686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their ability to transport pollutants makes them particularly dangerous, underscoring the urgent need for effective removal methods. Herein, we report the synthesis of an environmentally friendly material that enables the magnetic removal of polystyrene nanoparticles (PSNPs) from aqueous solutions by green chemistry approach. The material synthesized by using pine resin extract as a reducing and capping agent is iron oxide magnetic nanoparticles (PR@Fe₃O₄ MNPs). Spectroscopic (UV–Vis, FTIR) and microscopic (EFSEM, EDXS) techniques were used to characterize the nanoparticles and confirm the adsorption of PSNPs on the PR@Fe₃O₄ MNPs. X-ray diffraction (XRD) patterns indicated the crystalline nature of the nanoparticles and confirmed the preservation of the structure of PR@Fe₃O₄ MNPs after adsorption. The adsorption of PSNPs (with a diameter of 100 nm) was performed under varying conditions, including different contact times, dosages of PR@Fe₃O₄ MNPs, and concentrations of PSNPs. It was observed that the removal efficiencies of PSNPs (100 mg/L) ranged from 95.45% to 99.13% when the dosage of PR@Fe₃O₄ MNPs increased from 2.5 mg to 10.0 mg after 24 h, reaching the maximum adsorption capacity at 454.55 mg/g. Kinetic and isotherm studies indicated that the adsorption process fits best to a pseudo-second-order kinetic model and Langmuir isotherm, suggesting monolayer adsorption on homogeneous surfaces. Finally, the results of this study concluded that the green-synthesized PR@Fe₃O₄ MNPs can be used as effective and eco-friendly materials to remove PSNPs from aquatic environments.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":628,"journal":{"name":"Journal of Environmental Health Science and Engineering","volume":"23 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While rare in Earth’s early continental crust, the eastern Kaapvaal Craton in southern Africa may harbor the oldest known tin-bearing granites. Here we present a perspective of early continental evolution from the study of Archean detrital cassiterite from the volcano-sedimentary continental cover succession of the Dominion Group of the western Kaapvaal Craton. The cassiterites yield a concordia age of 3084.7 ± 2.3 million-year-old, representing the oldest detrital cassiterite ever found. They are enriched in hafnium, zirconium, niobium, and tantalum, depleted in tungsten, and have overall consistent δ18O values (mostly 3‒5‰) but heterogeneous δ122/118Sn values (−0.59 to 0.79‰). They likely originated from erosion of peraluminous granites, forming immediate basement of the Dominion Group. The occurrence of ~3.08 billion-year-old detrital cassiterite suggests widespread tin mineralization in the granites, the intrusion of which led to stabilization of the Kaapvaal craton. A detrital cassiterite found in the Kaapvaal Craton, South Africa, implies widespread tin mineralization and stabilization of granitic cratons approximately 3.08 billion years ago, as shown by U-Pb geochronology, trace element and oxygen and tin isotopes.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":" ","pages":"1-9"},"PeriodicalIF":8.1,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43247-024-01971-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving this goal with green processes and fully bio-based materials remains challenging, placing significant strain on the environment and energy resources. The key lies in mastering the appropriate material matching strategy and its mechanism for the forming of membrane structure. Here, ethyl cellulose (EC) / tea polyphenol (TP) / betaine (BT) bimodal nanofibrous membranes were fabricated by blended electrospinning using green solvents. The synergistic interaction between TP and BT termed the \"small molecule mutual support mechanism\", is particularly compelling. TP could prevent polymer chains from being difficult to deform because of BT, making it good spinnable even under high BT loading. In this case, the cations of BT were sufficient to cause jet splitting, forming a bimodal structure. Consequently, high-performance antibacterial air filtration had been achieved under ultra-light and ultra-thin conditions (15% and 8% of N95 masks, respectively). The filtration efficiency for 0.3 μm NaCl particles, pressure drop, and quality factor were 99.79%, 58.7 Pa, and 0.1050 Pa^-1, respectively. The antibacterial rates for <em>Escherichia coli</em> and <em>Staphylococcus aureus</em> were all 99.99%.

Circular economy (CE) principles provide a promising framework by emphasizing resource optimization, waste reduction, and the extension of asset life cycles while emerging digital technologies such as the Internet of Things (IoT), artificial intelligence (AI), blockchain, and 3D printing are instrumental in driving this transition by enhancing resource flow optimization, predictive maintenance, and real-time decision-making. This study uses the PRISMA methodology to critically analyze the existing literature and propose a theory-supported framework through a systematic literature review. The conceptual framework and theoretical propositions present the triad interaction between circular economy (CE) practices and digital technologies within the context of transportation infrastructure. This integration of relevant theories is key to enhancing practical applications for improved efficiency, while also promoting circular economy practices in transportation using these technologies. This study provides a foundation for future research and practical applications, contributing to a more sustainable and resource-efficient transportation sector.

The experimental results show that rock and concrete are damaged to different degrees under the action of wet and dry circulation. The micropore content of the whole sample increased and the medium and macro pores expand continuously during the dry–wet cycle action. The cracks development with the increase of number of dry–wet cycles intensify the damage of the sandstone-concrete connection surface.

Short-term load forecasting can provide crucial utility for effective energy transition and optimal energy management with informed decision-making at grid-level. The existing forecasting models predominantly implement deep learning techniques targeting individual buildings. This reduces the model’s tendency to account for the inter-building effect while forecasting demand across multiple buildings simultaneously. Also, the existing models often overlook instantaneous peaking patterns of the buildings, leading to sub-optimal learning and predictions. Thus, to address these challenges, this study introduces a novel dual-channel encoded bi-directional long short-term memory (LSTM) load forecasting model. The proposed model is fortified with attention mechanisms, residual connections, and quantile-based metrics that specifically target the erratic peaking patterns across multiple buildings simultaneously. The proposed model is purposely architectured following an encoder-decoder scheme to extract critical local and global temporal patterns and predict electrical demand across multiple buildings simultaneously. The proposed model is tested utilizing the demand data from a Canadian university and the results are compared to the recurrent neural network-based LSTM models. The proposed model improves the average root mean square error ranging from 1.8% to 10.9% and the average mean absolute error ranging from 33.6% to 59% as compared to the existing models.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"32 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interconnected river-lake systems feature multiple lake regions, wherein numerous rivers interconnect various lake regions. Their intricate hydrological conditions and interactions distinguish them from conventional lakes, which typically have a single and relatively static water body. However, the greenhouse gas emission characteristics, as well as the driving forces of the interconnected river-lake systems, are still under-researched. Here, we carried out bi-seasonal in situ surveys across a typical interconnected river-lake system, Dongting Lake, along with a meta-analysis derived from 168 lakes spanning six continents, to elucidate this issue. We found that interconnected river-lake systems exhibit a unique temporal variation in carbon dioxide and nitrous oxide fluxes, with positive fluxes during the wet season but transitioning to sinks during the dry season. Greenhouse gas fluxes in conventional stable lakes are frequently correlated with abiotic factors, such as hydro-climatological conditions and trophic status. While in Dongting Lake, specific microbial species that are important to the cycling of macronutrients and other less common nutrients, alongside microbial predatory behaviour, can better predict greenhouse gas fluxes. Our study highlights the importance of biotic predictors in prospective greenhouse gases flux estimates. River-lake ecosystems act as carbon dioxide and nitrous oxide sources in the wet season and sinks in the dry season, according to an analysis of greenhouse gas emissions from Dongting Lake, China, combined with a global-scale meta-analysis.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":" ","pages":"1-13"},"PeriodicalIF":8.1,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43247-024-01912-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
