Here we test the hypothesis that, early in the speciation process, female promiscuity promotes a reduction in overlap in sperm length distributions among songbird populations. We assembled a data set of 20 pairs of populations with known sperm length distributions, a published estimate of divergence time, and an index of female promiscuity derived from extrapair paternity rates or relative testis size. We found that sperm length distributions diverged more rapidly in more promiscuous species. Faster divergence between sperm length distributions was caused by the lower variance in the trait in more promiscuous species, and not by faster divergence of the mean sperm lengths. The reduced variance is presumably due to stronger stabilizing selection on sperm length mediated by sperm competition. If divergent sperm length optima in allopatry causes conspecific sperm precedence in sympatry, which remains to be shown empirically, female promiscuity may promote prezygotic isolation, and rapid speciation in songbirds.</p>","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"134-143"},"PeriodicalIF":3.1,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142557429","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}

Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) like citalopram, are frequently detected in European surface waters. Acute laboratory studies have demonstrated that citalopram can inhibit algal growth, immobilise <em>Daphnia magna,</em> and may result in foot detachment (i.e. the inability to adhere to a substrate) in snails. However, research on long-term citalopram exposure is scarce, and our understanding of its effects on aquatic community- and ecosystem-level is limited. Therefore, we investigated the impact of 13-week exposure to 0.01, 0.1, 1, 10 and 100 μg/L citalopram in outdoor freshwater mesocosms, focusing on water quality variables (i.e. pH, dissolved oxygen, electrical conductivity, temperature, algal chlorophyll-a, turbidity) and the structure of aquatic communities, with a special focus on mollusc foot detachment (<em>Lymnaea stagnalis, Planorbis</em> sp. and the total snail population).We found that environmentally relevant citalopram concentrations did not affect water quality variables, bacterial composition, zooplankton and macroinvertebrate communities. In contrast to expectations based on literature, snail foot detachment was not observed while the tested concentrations overlapped with the reported effect concentrations. This is in line with the absence of indirect adverse effects of foot detachment, such as population changes that could be the result of an increased vulnerability to predation or the inability to feed or reproduce. Reported sublethal effects in the literature, as found in laboratory studies, do not appear to lead to population- or community-level impacts in a semi-field experiment within the concentration range tested in this study. The experimental outcomes suggest that environmentally relevant concentrations of citalopram might not pose a threat to water quality variables, bacterial composition, zooplankton and macroinvertebrate communities, and snail foot detachment.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"14 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870014","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}

Recent work by Fry has used quantitative genetic models to argue that in many cases, including when there are direct benefits (a fecundity advantage to mating with the preferred male), direct and indirect selection may be of similar magnitude. Here, I use population genetic models, in which the strength of the genetic correlation is an emergent property of evolution at mating preference and display trait loci, to assess the relative contributions of direct and indirect selection to the evolution of mating preferences. For the cases of direct benefits and of indirect benefits with fixed and frequency-dependent search costs, I outline parameter values of fecundity benefits, preference strengths, and search costs for which indirect selection on female preferences can potentially predominate. I also analyze male mate choice under polygyny, showing that direct selection will always outweigh indirect selection except when there are direct benefits.</p>","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"51-64"},"PeriodicalIF":3.1,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142344232","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}

Genome-wide screening has proven to be a powerful tool in identifying critical genes associated with the toxicity of exogenous substances. To identify undiscovered key genes involved in AAI-induced renal toxicity, a genome-wide CRISPR library screen was conducted in the human kidney-2 (HK-2) cell line. Among the altered sgRNAs, a significant enrichment of those targeting the E2F transcription factor 1 (E2F1) gene was observed in surviving HK-2 cells in the AAI-treated group. Interestingly, the role of E2F1 had not been previously explored in studies of AAI nephrotoxicity. Further investigations revealed that E2F1 promotes apoptosis by activating the p53 signaling pathway and upregulating pro-apoptotic genes, such as BAK and BAX. Additionally, using the high-throughput experiment- and reference-guided database of traditional Chinese medicine (HERB), cannabidiol (CBD) was identified as an inhibitor of E2F1 by suppressing the activity of NF-κB pathway. In vitro and in vivo models confirmed that CBD inhibits AAI-induced upregulation of E2F1, thereby suppressing p53-mediated apoptosis. In conclusion, this study highlights the crucial role of E2F1 in AAI-induced renal cell apoptosis and identifies CBD as a novel therapeutic candidate for mitigating AAI nephrotoxicity.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"31 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870074","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}

According to the results, the modified PA with powder activated carbon (PAC) could successfully reduce the level of total suspended solids (TSS), turbidity, polycyclic aromatic hydrocarbons (PAHs), oil and grease to below the DW standards but failed to efficiently remove some heavy metals (HMs) and nutrient pollutants. The results revealed that the treated stormwater was an appropriate medium for microalgae cultivation. <em>Chlorella sorokiniana</em> cultivation in the treated stormwater reduced the concentration of HMs and nutrients to below the DW standard: Cr = 9.45 μg/L, Pb = 0.17 μg/L, Cd = 0.003 μg/L, COD = 1.18 mg/L, total nitrogen (TN) = 0.04 mg/L and total phosphate (TP) = 0.006 mg/L. In addition, microalgae could completely consume CO₂ and increase dissolved oxygen (DO) when different concentrations of CO₂ (natural air, traffic air and tunnel with and without ventilation) were injected into the culture medium. A final biomass concentration of 2.6 mg/L was achieved under the optimal conditions which contained 41%, 35% and 22% of carbohydrate, protein, and lipid, respectively. Based on the results, the PA permeability was reduced by 27.3% after 12 times filtration due to the PA blockage phenomena. However, with defined maintenance, the BGI system could have proper workability for several years (i.e. 80% efficiency after 5 years). Our findings suggested that the BGI system can be implemented in both centralized and decentralized fashions which results in clean water, CO₂ bio-fixation and high-value bioproducts from stormwater.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"82 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870076","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}

Despite the importance of integrating ecology and evolution in models of host-pathogen dynamics, there are few wild populations for which long-term ecological datasets have been coupled with genome-scale data. Tasmanian devil (Sarcophilus harrisii) populations have declined range wide due to devil facial tumor disease (DFTD), a fatal transmissible cancer. Although early ecological models predicted imminent devil extinction, diseased devil populations persist at low densities, and recent ecological models predict long-term devil persistence. Substantial evidence supports the evolution of both devils and DFTD, suggesting coevolution may also influence continued devil persistence. Thus, we developed an individual-based, eco-evolutionary model of devil-DFTD coevolution parameterized with nearly 2 decades of devil demography, DFTD epidemiology, and genome-wide association studies. We characterized potential devil-DFTD coevolutionary outcomes and predicted the effects of coevolution on devil persistence and devil-DFTD coexistence. We found a high probability of devil persistence over 50 devil generations (100 years) and a higher likelihood of devil-DFTD coexistence, with greater devil recovery than predicted by previous ecological models.

In COP26, most countries pledged to reduce carbon emissions from different business operations to achieve the net zero (NZ) mission. Many SCL organizations struggle to identify major roadblocks and strategic roadmaps for improving NZ challenges through innovative business frameworks. Therefore, this paper explores the NZ barriers from the theoretical lens of institutional theory (IT) and resource-based view (RBV) theory to analyse the NZ challenges. The proposed framework consists of <em>six</em> major dimensions based on IT and RBV and is further extended into <em>thirty-two</em> sub-dimensions. Two-stage multi-criteria decision-making methods, such as fuzzy Delphi and the best-worst method, are used to solve the proposed framework. The proposed hierarchical framework has been validated by Indian SCL organizations. The computational results show that operational and organizational factors are significant roadblocks to adopting NZ practices. The infancy and anxiety of carbon-capturing technology are major concerns for organizations dealing with NZ practices. The lack of technological maturity in carbon-neutral technologies is found as major challenge for SCL organizations to implement NZ practices in SCL operations. The managerial implications and recommendations for improving NZ barriers are proposed with an innovative operational, organizational, technological, and human (O2TH) framework. The O2TH-based strategies are presented to improve the adoption of NZ practices. The future scope is also presented in the conclusion section.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"275 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870017","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}
