Special Issue Information

Dear Colleagues,

Global climate change, as one of the most critical issues in ecosystem sustainability, is recognized as a major threat to wetlands. Climate change will cause significant changes to temperature regimes and precipitation patterns, which may pose serious risks for aquatic and wetland ecosystems. The UN reported that 85% of wetlands present in 1700 were lost by 2000, disappearing three times faster than forests. Increased wetland water temperatures will cause a shift in the thermal suitability of aquatic habitats for resident species, seasonal shifts in runoff will negatively impact on many aquatic ecosystems, patterns of greenhouse gases emission and carbon sink and source will be altered, etc. Alterations in the temperature, hydrological regime, biota matrix, and elements’ biogeochemical processes have caused and will continue to cause massive damage to the ecosystem service functions that aquatic and wetland ecosystems can provide. However, wetlands can also help to mitigate the impact of climate change. Therefore, there is an urgent need to fully understand the sustainability of aquatic and wetland ecosystems under climate change.

This Special Issue of Sustainability focuses on the effects of climate change on aquatic and wetland ecosystems. We invite the submission of papers dealing with ecological risk assessment for wetland ecosystems, patterns and dynamics of community structures, ecosystem processes’ functional sustainability, ecosystem restoration, etc. New approaches to derive risk assessment and management in wetlands are also of interest. New research papers, reviews and case reports are welcome, as well as methodological papers, brief reports, and commentaries. 

We look forward to receiving your contributions.

Wetlands are vital ecosystems in the Tibetan Plateau that play a crucial role in water conservation, flood storage, and biodiversity maintenance. They are sensitive to climate change and typically have high ecological and environmental quality levels due to minimal human disturbance. This study aimed to quantify landscape pattern changes within the Nagqu Hangcuo National Wetland Park (NNWP) and identify the impact of climate on wetland change. Using remote sensing data from six periods (1990, 1995, 2000, 2005, 2010, and 2015), dynamic change analysis, landscape pattern analysis, and correlation analysis were employed to determine the evolutionary features of the wetland landscape and explore their relationship with climatic factors. The results showed that the total wetland area increased from 15.11 km2 in 1990 to 15.23 km2 in 2015. The meadow area increased the most among landscape types, primarily converted from swamps. Over 25 years, the fragmentation of the NNWP’s landscape increased while diversity decreased and its shape became more complex. Meadows were more sensitive to climatic factors than other landscape types, with correlation coefficients between wetland separation and sunshine duration being more significant than other climatic factors. Therefore, it is imperative to monitor landscape pattern changes and the effects of climate change to better protect wetland parks through long-term planning, suitable mechanisms, and advanced technology.

Many phosphorus release experiments have been conducted in the water level fluctuation zone (WLFZ). However, the effects of rhizospheres on the risk of soil phosphorus release remain unclear. In this study, twenty-four soil samples were collected from the WLFZ of the Pengxi River, the largest tributary of the northern Three Gorges Reservoir. Physicochemical properties, phosphorus forms and phosphatase activity in rhizosphere and near-rhizosphere soils were investigated. Both the total phosphorus (TP) and water-extracted organic phosphorus (H2O-Po) contents were significantly higher in rhizosphere soils than in near-rhizosphere soils (p < 0.05). Enrichment rates (ER) of TP and H2O-Po were 42.4% and 180.3%, respectively. Significant increases were also found in activities of acid phosphatase, alkaline phosphatase, and phosphodiesterase in the rhizosphere, and corresponding ERs were 95.3%, 76.1%, and 22.0%, respectively. Environmental factors, such as pH, organic matter, and amorphous manganese, made significant contributions to the variations of phosphorus forms and phosphatase activities. The risk of phosphorus release to water in the rhizosphere soils of the study area increased slightly, according to the water-extracted phosphorus index. This risk may further increase due to flooding, as plant uptake of soil phosphorus would be inhibited while inorganic phosphorus is still generated by phosphatase. Full article

Climate change, river pollution and loss of biodiversity are increasing and becoming global environmental concerns. The Yellow River is China’s mother river, providing water for about 114 million residents in towns and cities along its route. Yet in 2012, the Yellow River received 4.474 × 109 tons of sewage containing a large number of exogenous pollutants, posing a huge ecological and public health threat. Water quality safety is not only a matter of ecosystem health but also of human survival and social development. Therefore, the effects of pollutants on water quality safety should be carefully studied, which is important to ensure the sustainability of the Yellow River and the surrounding cities and towns. In this study, water and sediment samples from the Jishan River of the Juancheng, a typical city in the lower reaches of the Yellow River, were collected and evaluated by integrating the traditional physicochemical water indicators, benthic Index of Biological Integrity (B-IBI) and zebrafish embryotoxicity test. The results showed that water dissolved oxygen, pH, total nitrogen and total phosphorus were strongly correlated with zebrafish embryonic teratogenicity, lethality, abundance index and Shannon Winner index. A total of 21 benthic species were collected, including mollusks, arthropods and annelids, with the upper reaches having the largest biomass and B-IBI values indicating the urban reaches have better biological integrity than rural reaches. The teratogenic rate of zebrafish embryos in raw water was greatest in rural rivers and was significantly different from the negative control (p < 0.05). When exposed to 100 mg/mL sediment samples, embryo hatching rates were inversely correlated with teratogenic rates, with lethal rates reaching over 96% in all rural reaches. The results showed that the water quality safety at the rural farms in the Yellow River transfer-type towns is poor, and they especially recommended that the river near the farms in rural areas should be monitored with emphasis.
