Though a designated Ramsar site, Sasthamkotta Lake has been exposed to various anthropogenic stressors, which in recent years have caused a sudden decrease in its productivity. The study therefore aimed to delineate the present ecological health of the lake in terms of its trophic dynamics and ecosystem efficiency using ecosystem modeling approach. The estimated trophic level (TL) of the lake ranged between 1 (detritus) to 3.76 (fish-eating birds), indicating a skewed structure towards lower carnivorous groups. The ecosystem maturity indices (connectance index, and system omnivory index) revealed the lake to be immature and in the developing stage, though the origin of the lake has been traced back to the quaternary era. The higher value of system overhead (66%) denotes that this ecosystem has been resisting ecological perturbations, in spite of its age is noteworthy. Though the study indicates that the lake’s trophic structure is well-established, a variety of anthropogenic stressors reduce ground water levels and diminish aquifer recharge into the lake. This would significantly reduce the lake’s catchment area, affecting the entire biota. The results presented here is a pioneering attempt to understand the current ecological condition and impact of future possible stressors that need to be monitored for ensuring ecosystem integrity of the lake.</p>","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"45 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140939106","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}

Within the regulation services, wetlands soils have an important role in regulating the water cycle through water retention and the climate through carbon storage and sequestration. The objective of this research was to estimate the water retention capacity and the soil organic carbon content in the superficial portion of Ramsar wetlands soils in Quintana Roo, Mexico, to provide elements to the ecologic and economic valuation of regulation ecosystem services. A total of 268 soil samples were collected from the upper 20 cm soil layer, soil samples were processed and analyzed to obtain edaphic properties and organic carbon. We assessed the effect of 1) seasonality, 2) vegetation structure, and 3) soil type in the response variables water retention and organic carbon storage. The results indicate that the volumetric content and saturation degree were different among wetlands. Seasonality was not a significant factor in the assessment of these two regulation ecosystem services. The mean water storage capacity was 0.65 g water/cm³ of soil, representing from 500 to 1000 L water/m³ soil. The greatest carbon storage values were associated with mangroves established on Solonchak, with values between 5 and 8 Mg C/ha.

Understanding how marsh communities are influenced by their environment is critical in determining their ability to respond to environmental stressors. Plants harbor microbes that colonize and inhabit their tissues without causing apparent harm (‘endosymbionts’). These endosymbionts provide benefits to host plants including mediation of salinity stress response, thus it is important to understand the factors influencing the diversity of endosymbiont communities. We examined the relative influences of biotic (host-related) and abiotic (local environment) factors on the endosymbiont communities associated with the dominant saltmarsh halophyte, <i>Batis maritima</i>. Using culture-based and genetic approaches, we characterized both fungal and bacterial endosymbionts from <i>B. maritima</i> roots in Oso Bay, Texas, along the Gulf of Mexico. Isolation frequency of endosymbionts significantly differed between fungi and bacteria, and the overall diversity was low. Belowground plant biomass and salinity correlated with decreased diversity in fungi, while shifts in fungal composition varied according to light availability. Overall, these findings highlight the relative influences of both biotic and abiotic factors in shaping the root endosymbionts and might differ between fungi and bacteria. Understanding these processes is fundamental to determining the resilience of both endosymbionts and host plants, with implications for ecosystem functions amidst environmental pressures. As anthropogenic-driven environmental changes continue to rise, insights gained from these results can inform future coastal restoration and management especially of at-risk coastal ecosystems.</p>","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"44 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140826856","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}

A multitemporal analysis of land cover maps was conducted, utilizing visual interpretation of aerial orthophotos from the summer seasons of 1996, 2008, 2015, and 2021. Landscape changes were evaluated by transition matrices and chord diagrams. Maps were classified in accordance with CORINE land cover types at a fourth level of detail. The multitemporal analyses provided a comprehensive overview of landscape changes within the reserve over the past 25 years. The most notable changes were the increase of wetland areas and the reduction of agricultural and artificial areas. Moreover, seminatural vegetation constantly extended over time. These changes reflected the continuous management activities within the nature reserve, encompassing agreements for water supply, restoration projects, and measures to counteract illegality. These operational actions induced fine-grained ecological changes (outcomes at ecosystem level). This study highlighted the importance of remote sensing and landscape analysis, matched with fine-grained management data, as tool for long-term monitoring.

The study further reveals that Ghana is a signatory to many international environmental conventions and treaties irrespective of the required obligations and commitments. However, the translation of the obligations of these conventions and treaties into local laws and policies, their implementation and enforcement have been woefully inadequate. Institutions mandated to oversee these processes are under-resourced or undermined by a multitude of issues. Whilst the Kumasi Metropolitan Assembly and its planning and hydrological units have the personnel and technical competence to deal with wetland issues, the National Disaster Management Organisation, on the contrary, has the financial and logistical support without the needed technical competence to manage wetland and flood challenges.

At a freshwater mitigation wetland, built in a former agricultural field to compensate for development-related wetland losses elsewhere, we conducted a manipulative field experiment using organic matter amendments to identify the effects different types and loading rates had on the development of soil (organic matter, bulk density, and hydric soil indicators), vegetation (root and shoot biomass, floristic quality), and methane (CH₄) emissions. The amendments included cow manure, composted wood chips, and hay at various loading rates, and municipal wastewater Class A biosolids. We found that there were trade-offs in desired restoration outcomes. Experimental loading rates of hay (226 m³ ha⁻¹) and manure (339 and 678 m³ ha⁻¹) produced more CH₄ (78–92 g m⁻² year⁻¹) than unamended plots (28 g m⁻² year⁻¹). These same amendments had little effect on hydric soil indicators (e.g., redox potential and reduced iron). Manure almost doubled vegetation biomass (937 g m⁻² versus 534 g m⁻²) compared to the unamended control, largely due to the growth of <i>Typha</i> sp. (cattail), an undesired plant at this site that resulted in lower floristic quality. Compared to unamended soils, only wood chips appeared to increase soil organic matter after one growing season. All amendments tended to reduce soil bulk density and penetration resistance, but these were not correlated with root growth. Unexpectedly, hydrology varied considerably due to patchy soil characteristics, despite little variation in elevation – this strongly influenced on our results. We qualitatively observed that constantly inundated plots had lower CH₄ emissions than areas with wet-dry cycles and that cattail proliferated mostly in wetter areas. Contrary to the prescription of organic matter amendments as a method for accelerating soil and vegetation development in wetland restoration projects, our findings demonstrate that amendments may not be necessary to support vegetation and hydric soil development and might unnecessarily exacerbate atmospheric warming and contribute to invasive species spread.</p>","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"20 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140044349","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}
