The seasonal pattern of energy allocation among the different organs was evaluated in the snail <i>Zidona dufresnei</i>. The somatic indexes, energy density and energy content of the gonads, digestive gland, foot, and secondary sexual glands of <i>Z. dusfresnei</i>. The lowest foot index (FI), energy density and energy content were found in winter. The high digestive gland index (DI) and energy content (EC<sub>DIG</sub>) observed in spring likely coincide with the peak of productivity. The male’s gonads did not show seasonal energetic variation, although the gonadosomatic index (GI) of males was lower in summer than in other months. The mass and energy content of the albumen and capsule glands exhibited a decreasing pattern from spring to winter. The foot is suggested as the main energy reservoir in <i>Z. dufresnei</i>, the digestive gland as an energy reservoir that contributes to the gonadal maturation, whereas the energy of the capsule and the albumen glands contributes to the spawning. This study highlights seasonal variations in the energy content of the foot (edible compartment) and the significance of secondary sexual glands in understanding the bioenergetics of <i>Z. dusfresnei</i> and offspring fitness. These findings should be taken into consideration in fisheries management decisions for this ecologically and commercially important species.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"58 4","pages":"1097 - 1106"},"PeriodicalIF":1.7,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141947732","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}

The dominant phyla identified were <i>Proteobacteria</i>, <i>Actinobacteriota</i>, <i>Bacteriodota</i>, and <i>Cyanobacteria</i>. The presence of the <i>Alphaproteobacteria</i> and <i>Gammaproteobacteria</i> indicates that the Seine River water nutrient profile is mainly determined by the recalcitrant organic compounds present in WWTP effluents. Bacterial diversity showed significant temporal variability with a highly significant difference in bacterial composition between 2020 and 2021, probably due to variations in water flow favoring <i>Cyanobacteria</i> growth. Summer displayed higher microbial activity and abundance than autumn, attributed to temperature and orthophosphate content. Spatial variation in bacterial composition was observed between sites upstream and downstream of Paris, as well as before and after of the Seine Valenton-WWTP, subject to an accumulation phenomenon and impacted by wastewater treatment. Further assessment of emerging contaminants and other pollutants is required to better understand these variations.

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}
