Urban wetlands are increasingly being used to manage stormwater, provide valuable resources for biodiversity, and to improve public amenity and wellbeing. However, community concern regarding an increase in the abundance of mosquitoes that pose risks to public health can severely undermine support for these habitats. Our limited understanding of relationships between wetlands, aquatic biodiversity,...
This paper aimed to explore the effects of Spartina alterniflora invasion on the contents and structure of soil dissolved organic matter (DOM, including dissolved organic carbon (DOC), dissolved organic nitrogen (DON), dissolved organic phosphorus (DOP), and dissolved organic sulphur (DOS)) in the Yanghe estuary, by the aid of ultraviolet-visible spectrum, three-dimensional fluorescence spectrum,...
Alterations to Louisiana’s river systems and local hydrology have resulted in reduced freshwater, sediment, and nutrient inputs to wetland landscapes, causing significant negative impacts on marsh productivity and stability. This study set out to assess regional- and basin-scale impacts of river connectivity and sediment availability on wetland productivity. Satellite data were used in conjunction...
Sphagnum wetlands in subtropical high-mountain regions have been severely destroyed by human activities, necessitating restoration efforts. We studied the effects of substrate and planting method on Sphagnum palustre L. growth and the underlying mechanisms to determine the optimal conditions for S. palustre restoration. S. palustre collected from natural wetlands was grown on nine substrates and with...
Hydric soil identification utilizes diagnostic morphologic features, including iron transformations, resulting from anaerobic conditions. However, soils derived from some red parent materials (RPM) fail to develop characteristic hydric soils morphologies, confounding hydric soil and wetland delineation. Laboratory and field methods addressing resistant RPM soils exist, but application remains limited...
Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases in Typha abundance in wetland ecosystems throughout North America at a cost to native floral and faunal biodiversity. As demonstrated by three regional case studies, Typha is capable of rapidly colonizing habitats and forming monodominant vegetation stands due to traits such...
The interactions between soil organic matter (SOM) and micro-topography and vegetation drive the ecology of wetland ecosystems. We investigated the distribution pattern of SOM and its relationships with elevation, slope, aspect, topographic wetness index (TWI), and normalized difference vegetation index (NDVI) in Poyang Lake, the largest freshwater lake of China. The local parameters were obtained...
The recovery of wetland function after tidal flow restoration may be influenced by water pollution and sea level rise. Our objective was to examine the effects of tidal flow restoration on denitrification potential and carbon (C) mineralization across an urban coastal landscape. Soil cores were collected from 32 tidal wetlands in Connecticut, U.S.A., spanning a wide range of salinity (0.3–29 ppt)...
Coastal wetlands are receiving basins for inland runoff that contains numerous compounds such as nutrients and herbicides, which may have negative effects on wetland plants. Spartina patens is a dominant emergent macrophyte in low salinity wetlands whose biomechanical properties contribute to wetland stability against erosive forces and herbivore grazing. We conducted two greenhouse experiments with...
Spotted salamanders (Ambystoma maculatum) require vernal pools for breeding habitat. Limited protection and preservation of vernal pools makes suitable habitat creation important. Differences in corticosterone levels, a hormone associated with growth, development, and stress in amphibians, could indicate population health and habitat quality. Our objective was to determine if habitat characteristics...
Cranberry agriculture once represented over a third of wetlands in the New Jersey pinelands, but many bogs have been abandoned as the industry has declined. The purpose of this study was to examine succession dynamics of cranberry bogs post abandonment in the New Jersey pinelands and also provide data on the association of local species in various ages of abandoned cranberry bogs in order to inform...
The Oribatida is the most abundant and diverse group of mites and one of the most abundant groups of invertebrates in bogs, important for the decomposition of organic matter. These mites are relatively poorly studied in bogs and their seasonal dynamics have never been investigated in detail throughout the year. The study was performed on the periphery of a bog pond located in north-eastern Poland...
Wetland construction can mitigate the biodiversity and water quality losses associated with reduced natural wetland coverage. While beneficial effects of wetland construction for bats have been observed in natural and rural settings, the effects of wetland construction on bats in an urban ecosystem are less understood. We used passive acoustic monitoring to measure bat activity levels and diversity...
Crustacean community structure and dynamics are very well studied in lakes, rivers and oceanic systems but wetlands, where moisture conditions fluctuate, have not received equal attention in research. For example, cladoceran communities in peatland systems in the subarctic region have not been fully investigated. We used paleolimnological and paleoecological methods to study plant and cladoceran assemblages...
The Shallow Lakes Restoration Project aims to restore eutrophic shallow lakes throughout the Iowa Prairie Pothole Region (PPR). We compared the vegetation taxa richness and frequency of taxa in three vegetation groups surveyed in 2016 and 2017 across non-restored sites, younger restorations, and older restorations. We also assessed the impact of these groups on numbers of breeding marsh birds. Restored...
This study aims to understand the effects of recent tree encroachment on plant richness and diversity of Sphagnum-dominated bogs isolated in an agricultural landscape. A nested paired sampling design was used to compare plant species richness and beta diversity between open and forested habitats of 14 bogs in southern Québec, Canada. We evaluated the impact of tree encroachment at regional and local...
Although landscape indicators are widely used to assess wetland ecological condition, how they capture the spatial arrangement of land cover is not well addressed. We conducted a Level 1 Landscape Assessment to revise strengths and weaknesses of landscape indicators when links to ecological conditions are strong. Wetland sites mapped by the National Wetlands Inventory were defined as 1-km radius circles...
