The bioclimatic, edaphic, elevation, and slope variables were obtained from specialized platforms. Thus, to generate species distribution models, Support Vector Machine, Random Forest and Generalized Linear Model algorithms were used. All predictions of the model for a species were combined to obtain its final model (Ensemble) for the present and future scenarios. As a result, definitive hosts of the parasites showed high climatic suitability. The broad niche of these species indicated that these organisms can show certain opportunistic and generalist characteristics. Unlike their parasites that revealed a more restricted distribution than their host. Also, in a future scenario, endoparasite species will generally reduce 99% of their populations, ectoparasites 93%, while some hosts will increase their populations. In conclusion, the study assumed that future climatic events can influence parasites and their hosts differently, whereas anthropization can influence parasite extinction even without directly affecting their hosts.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"58 3","pages":"999 - 1011"},"PeriodicalIF":1.7,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141612023","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}

To gained a comprehensive understanding of the response strategies existed by the leaf traits of <i>Aegiceras corniculatum</i> and to identity the key factors that drive leaf traits variation in the response to shrimp aquaculture wastewater, we sampled leaves of <i>A. corniculatum</i>, sediments and interstitial water from non-discharge area (CK), direct discharge area (DDA) and landfill restoration area (LRA) in Qinzhou Bay in southeast coast of China. We established a correlation between leaf vein traits and stomatal traits and abiotic conditions such as pH, nutrient content in sediment. In comparison to CK and LRA, leaf vein traits (primary vein diameter, secondary vein diameter, tertiary vein diameter, enclosed circular area, vein spacing, and tertiary vein density) exhibited a decrease in DDA. This observation suggests that the persistent discharge of shrimp aquaculture wastewater exerts a detrimental impact on the leaves’ mechanical support, nutrient, and water transport capacity. Furthermore, a marked negative correction emerges between stomatal density and length. In contrast, within LRA, an increase in stomatal density and a corresponding reduction in stomatal length indicate a heightened transpiration function of the leaves, thereby enhancing the efficiency of water and inorganic salt transport. Subsequently, the leaf vein traits in LRA are observed to be higher than in CK, suggesting that the leaf traits of <i>A. corniculatum</i> has undergone pre-adaptation to DDA and possesses high phenotypic plasticity. Through the analysis of leaf vein and stomatal traits in diverse shrimp aquaculture wastewater discharge habitats, this study demonstrates that such pre-adaptation and elevated phenotypic plasticity facilitates the adaptation of <i>A. corniculatum</i> to the challenging shrimp aquaculture wastewater environment.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"58 4","pages":"1033 - 1048"},"PeriodicalIF":1.7,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141567180","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}

In the present study, a hybrid model, Extreme gradient boosting (XGBoost)-Artificial neural networks (ANN), was applied to forecast the distribution of <i>P. modestus</i> larvae and juveniles collected from a large estuary in northern Vietnam, which are driven by temperature and mangrove changes. Present results demonstrate the usefulness and applicability of ANN-XGBoost model in ecological studies, with an excellent estimation accuracy.
