Abstract:

Urbanization is among the largest threats to wildlife populations through factors such as fragmentation, isolation, and habitat destruction. Urban open spaces, such as parks and golf courses, have the potential to provide wildlife with suitable habitat within an urbanized matrix. These refugia may be particularly important for amphibians, which represent one of the most endangered and least vagile vertebrate groups on earth. During the spring and summer of 2018, we conducted surveys to determine the presence of anurans at 51 wetland sites within the Piedmont ecoregion of South Carolina. Nearly

Abstract:

Urban wetlands play a significant role in the sustainable development of the urban eco-environment. However, accelerated urbanization has caused rapid changes in urban wetland landscape patterns, which may seriously affect their functions. Based on land-use maps, TM images, and field data from the Wuhan wetlands, the spatiotemporal evolution and wetland landscape pattern were quantitatively analyzed, with reference to landscape ecology indices of diversity, fragmentation, dominance, shape, and dimension. The results showed that: (1) the natural wetland area decreased: lake wetlands and marsh w

Abstract:

Though microbial transformations are the primary mechanism of contaminant attenuation in wetlands, much remains to be known about microbial communities in urban wetlands. In this study, the microbial communities from urban wetlands with different runoff regimes (i.e., a contaminated remnant wetland, a constructed wetland, and a remnant wetland) were assessed for their capacity to attenuate and tolerate typical urban runoff pollutants. Results from denaturing gradient gel electrophoresis of 16S rRNA genes showed relatively high similarity in community composition among the wetlands. Community-l

An urban heat island (UHI) refers to urban areas that experience higher temperatures due to heat absorption and retention by impervious surfaces compared to the surrounding rural areas. Urban wetlands are crucial in mitigating the UHI effect and improving climate resilience via their cooling effect.

In western Texas, most wetlands are fed from precipitation runoff, making them sensitive to drought regimes, anthropogenic land-use activities in their surrounding watersheds, and the interactive effect between these two factors. We surveyed adult odonates in 133 wetlands (49 in grassland settings, 56 in cropland, and 28 in urban areas) in western Texas from 2003–2020; 33 species were recorded. Most species were widespread generalists, but urban wetlands had the highest species richness, as well as the most unique species of any of the three wetland types.

Rapid urbanization has drawn some aquatic environments into the urban texture from the outskirts of cities, and the composition and distribution of plant species in urban wetlands along the urban gradient have changed. Understanding the drivers of these changes will help in the conservation and utilization of urban wetlands.

Wetlands provide various ecosystem services to urban areas, which are crucial for sustainable urban management. With intensified urbanization, there has been marked loss of urban natural wetland, degradation, and related urban disasters in the past several decades. Rapid and accurate mapping of urban wetland extent and change is thus critical for improving urban planning toward sustainability. Here, we have developed a rapid method for continuous mapping of urban wetlands (MUW) by combining automatic sample migration and the random forest algorithm (SM&RF), the so-called MUW_SM&RF. Usi

Abstract:

Urban wetlands are ubiquitous landscape elements that affect the spatial pattern and functions of cities. Despite being rich and important habitats for a variety of birds, they are continually being isolated or lost. Isolation and loss negatively impact on the integrity of the urban landscape pattern and compromises on biophilic planning and development. Since urbanization is a continuous cultural process, it is important to investigate how its impacts, which are invariably in conflict with nature, would portend for aquatic bird communities in urban areas.

Urban constructed wetland, effectively used in sewage disposal and ecological restoration, has unique advantages in urban ecological construction. With the development of the ecological landscape concept, constructed wetland gradually has become an important urban ecological landscape. Based on ecological concepts, ecological principle, technical principle and aesthetic principle of planning and the layout, process, landscape, plants and other key issues of design were discussed for the constructed wetland.

Abstract:

Constructed floating wetlands (CFWs) are a highly efficient ecosystem restoration technology that can be used to improve stormwater quality and reclaim degraded urban shorelines to provide a wide variety of wetland ecosystem services. The concept of CFWs has its origins from naturally-occurring floating wetlands found around the world. They consist of a buoyant substrate that supports wetland plants growing hydroponically, with roots suspended below the water surface. They have the capacity to tolerate fluctuating water levels and variable nutrient loading and can be designed for a number of p

Wetlands play a number of roles in the environment, which are also considered the most biologically diverse of all ecosystems. Utilizing RS and the GIS software, remote datum were matched and classified. By these transactions, the temporal and spatial changes of wetland landscape are explored in Wuhu, combining qualitative analysis and quantitative methods. This paper analyzed the time-spatial revolution process which indicated that, firstly the area of wetland reduced rapidly from remote sensing image in 1988, 2001 and 2005, secondly the exterior of urban changed acutely and the interior were

Abstract:

The Sweetwater Authority's urban runoff diversion system (URDS) comprises constructed wetlands on a hillside between the town of Spring Valley and the Sweetwater Reservoir, California, USA. The URDS were designed to divert dry-weather and first-flush urban runoff flows from the Sweetwater reservoir. However, these constructed wetlands have developed into ecologically valuable habitat. This paper evaluates the following ecological questions related to the URDS: (1) the natural development of the species present and their growth pattern; (2) the biodiversity and pollutant stress on the plants an

Abstract:

Urban wetlands in Chilean cities are one of the urban ecosystems most affected by real estate developments. Despite their importance for recreation and biodiversity, they are constantly shrinking due to deficient urban planning processes. However, with the recent boom of green and sustainable cities, wetlands are being revalued through restoration projects and open urban parks, with natural value for the well-being of habitats and the urban population. In this sense, promoting accessibility through suitable infrastructure will contribute to improving the quality of life of inhabitants and the

Abstract:

Wetlands are valuable but threatened natural resources worldwide. While providing a wealth of environmental benefits, wetlands play a vital role in temporarily storing flood waters and thereby reducing the risk of damaging floods. This is important given the predicted impacts of climate change, especially along the world’s coastline and coastal cities. The continued expansion of urban areas is posing a risk to wetlands in and around metropolitan areas. In this article we examine wetland trends in urban areas in three Latin American countries – Chile, Colombia, and Peru.

China has experienced dramatic economic growth and social development, especially in the period between 1978 and 2008. The biodiversity and the socioeconomic sustainability in China were under threat, and the loss of wetlands was a significant aspect of ecological deterioration in the country at that time. However, the driving factors for the loss of wetlands are not well understood, probably due to a lack of accurate country-scale data. This study analyzes the changes in China’s wetland area between 1978 and 2008 (1978, 1990, 2000, and 2008) and the interchange between different wetland types

Abstract Urban lakes and wetlands are being more commonly used for the purpose of storing and treating stormwater. In some instances, a combination of both constructed wetlands and lakes are designed to further improve the efficiency of the system. The main aim of this paper is to compare the water quality between two urban stormwater lakes. A standalone lake system and a combined wetland/lake system were monitored for water quality. The results indicate that an integrated wetland and urban lake performs better than the urban lake alone. The improved performance was particularly significant in
