Physical vegetation management has shown deep and diverse impacts on fauna diversity and abundance. However, it is still unclear to what degree management influences Odonata (dragonfly and damselfly) in urbanized ecosystems. In order to understand the crucial factors among Odonata (adults and larvae) and physical vegetation management in a highly urbanized environment, this study investigated the response

The ecological effects of tropical cyclones on mangrove forests are diverse and highly location- and cyclone-dependent. Ecological resistance, resilience, and enhancement are terms that describe most mangrove forest responses to tropical cyclones. However, in the most extreme cases, tropical cyclones can trigger abrupt and irreversible ecological transformations (i.e., ecological regime shifts). Here

With projected increase in storms, sea-level rise and saltwater intrusion in low-lying terrestrial areas, compositional changes that favor more salt tolerant species are likely to occur. Wetland species are expanding into declining forested communities, primarily dominated by trees. Higher salinities for germination may preclude establishment of tree species. We examined the capacity for coastal tree

For providing a better understanding of the quantitative relationship between typical wetland vegetation and their tidal creek habitats in the Yellow River Estuary, the tidal creeks and three wetland vegetation types of Spartina alterniflora, Phragmites australis and Suaeda salsa were selected to analyze their distribution characteristics and explore the correlation between their spatial distributions

Bacteria are important soil components that function as both decomposers and plant symbionts and play a major role in plant–microbe interactions. However, little is known about the diversity of bacterial communities in the rhizosphere of the native invasive plant Echinochloa caudata. In this study, we used high-throughput sequencing to investigate bacterial communities in the rhizospheres of Echinochloa

We use the maps elaborated within the Mexican Mangrove Monitoring System (MMMS) project of the National Commission for Knowledge and Use of Biodiversity (CONABIO) to analyze the changes in mangrove area distribution during the last 45 years, within the framework of the coastal regional characteristics in Mexico. We found that 19% of the primary mangrove area identified in 1970/1980 was lost and that

Mangroves are known to sequester carbon at rates exceeding even those of other tropical forests; however, to understand carbon cycling in these systems, soil-atmosphere fluxes and gas exchanges in mangrove-adjacent shallow waters need to be quantified. Further, despite the ever-increasing impact of development on mangrove systems, there is even less data on how subtropical, greenhouse gas (GHG) fluxes

Based on retrieved results of literature and patents related to international wetland ecological restoration, the current status and development of ecological restoration techniques for degraded wetlands in both China and international states were analyzed synthetically. The results showed that the United States was the pioneering country in studies on the wetland ecological restoration, while China

Dredged materials from navigation channel maintenance represent a potentially valuable resource for wetland creation and restoration. In the northern Chesapeake Bay, fine-grained sediments from Baltimore Harbor approach channels are transported by barge southward for creation of wetlands on the site of an eroded island. High concentrations of ammonium, soluble reactive phosphorus, dissolved iron, and

Nitrogen pollution in wetland ecosystems has become a pressing global issue in recent years. The effects of redox potential on the environmental behavior of nitrogen remain elusive. In the present work, both field experiments and laboratory analyses have been carried out to characterize the spatial-temporal changes of dissolved inorganic nitrogen (NO3−, NO2−, NH4+) and redox potential in the riparian

In natural tidal marshes, nutrient fertilization stimulates complex responses, bringing into question the suitability of nutrient-rich dredged material as a substrate for tidal marsh restoration. We examined vegetation and elevation trends in the constructed tidal marshes at Poplar Island, Maryland where fine-grained dredged material (high nutrient) and locally dredged sand (low nutrient) were used

Beach ridges and wetland swales formed in embayments along Great Lakes shorelines during Holocene lake-level changes. Vegetation differences among swales suggested influence from differing groundwater flow systems. We characterized the hydrology across 79 ridge/swale wetlands in the Manistique/Thompson embayments of Lake Michigan using chemical and physical methods. Cross-sections were built from geologic

Potential impacts of climate change on the position of the wetland-hydrology boundary were estimated for four sites in the Eastern U.S. Precipitation and temperature predictions were obtained from the Hadley general circulation model (UKMO-HadCM3) because it most closely approximated observed precipitation for the period 1950–2000. The DRAINMOD hydrologic model was used to compute daily water table

We evaluated two rake-enclosure sampling methods for estimating biomass of submersed aquatic vegetation (SAV) within managed tidal impoundments (MTIs) in the Ashepoo-Combahee-Edisto Rivers Basin, South Carolina. We collected SAV using a modified rake within 0.086 m2 cylindrical sampler (CS), a non-modified rake within 0.2-m2 quadrat (QS), and after raking, hand-collected remaining SAV within each enclosure

Determining the economic value of wetlands is essential while creating sustainable wetland development plans and market-based ecological protection strategies. This paper studies the value of Begnas Watershed System by assessing the economic values of its selective ecosystem servicees. We conducted household surveys, multiple focus group discussions, stakeholder consultation, indepth interviews and

Elevated atmospheric CO2 may create greater methane (CH4) emissions from subarctic wetlands. To date such ecosystem feedbacks remain poorly understood, particularly in relation to how different wetland plant species will control such feedbacks. In this study we exposed plant-peat mesocosms planted with four Cyperaceae species to 400 and 800 ppm atmospheric CO2 concentrations and measured plant and

The invasion by emerald ash borer (Agrilus planipennis) of extensive black ash wetlands in the upper Great Lakes region of North America is expected to alter plant community structure and composition and, therefore, abiotic factors like temperature and hydrology. We conducted two experiments to examine how changes in leaf litter could alter ecosystem function via 1) changes in litter breakdown and

Wetlands are mapped across the USA for compliance with §404 of the Clean Water Act using field-collected data and protocols in the 1987 Federal Wetlands Delineation Manual (3-factor method). The National Wetlands Inventory (NWI) maps wetlands and deepwater habitats for management and policy-making using aerial image analysis with limited field verification. There have been few comparisons of maps other

It’s significant to probe hydrological connectivity within the estuarine area for implementing the ecological restoration experiment on the damaged coastal wetland and the methodology development of wetland eco-hydrology. We established the Integrated Accessibility Index to Marine and Freshwater (IAIMF) to evaluate the hydrological connectivity based on the accessibility principles. 1 km grid was setup

To investigate the spatial and temporal variations of sulfur (S) in plant-soil systems of Phragmites australis (PA, native invasive species) and Cyperus malaccensis (CM, common native species) marshes, in situ filed sampling was conducted in the two marshes at different seasons. Results showed that the variations of total sulfur (TS) contents in soils differed among seasons or marshes. Higher levels

Paddy fields play an important role as alternative habitats for various wetland-dependent species. Agricultural intensification in paddy fields, however, presents serious threats to these species. Here, we examined the environmental factors, including those related to modern farming practices, affecting the distribution of the Sado wrinkled frog (Glandirana susurra) in paddy fields on Sado Island,

The nematofauna of the Seekoeivlei Wetland in the north-eastern Free State province of South Africa was studied in order to determine its ecological status. Nematodes were collected in three different surveys, in October 2011, and in February and May 2012. Samples were taken from three sites within the reserve, each representing a different habitat. A total of 37 genera belonging to 21 nematode families

Tropical peatlands are an important carbon store and source of greenhouse gases, but the microbial component, particularly community structure, remains poorly understood. While microbial communities vary between tropical peatland land uses, and with biogeochemical gradients, it is unclear if their structure varies at smaller spatial scales as has been established for a variety of peat properties. We

Tidal salt marshes, as “blue carbon” ecosystems, play a critical role in mitigation of global climate change since their large soil organic carbon (SOC) pool. Drying-rewetting cycles induced by periodic tides have profound influence on soil carbon cycling in tidal salt marshes. However, the magnitude and mechaanism of the effects of drying-rewetting frequency on SOC loss in tidal salt marshes is still

We explored how a geographic information system modeling approach could be used to quantify supporting ecosystem services related to the type, abundance, and distribution of landscape components. Specifically, we use the Integrated Valuation of Ecosystem Services and Tradeoffs model to quantify habitats that support amphibians and birds, floral resources that support pollinators, native-plant communities

Vegetation changes in the Poyang Lake wetland related to the construction of the Three Gorges Dam (TGD) and climate change have received increasing attention in recent decades. However, due to the high spatial heterogeneity, the changes in wetland vegetation have not been well quantified at a large spatial scale. We addressed this challenge by using Moderate Resolution Imaging Spectroradiometer (MODIS)

Vallisneria natans is often used for the ecological restoration of aquatic vegetation. V. natans thalli were cultured under ambient (400 ppm) and increased carbon supply, with low (18 °C) and high temperature (25 °C). The thalli were used to examine the effects of increased carbon and high temperature on the growth, nitrogen metabolism and photosynthetic characteristics of this plant. At 18 °C, the

The assessment of wetland changes on the Tibetan Plateau (TP) is an important component of global change research. The Damqu River Basin (DRB) lies within the southern source of the Yangtze River and is part of the core wetlands area of the Three Rivers Source Region (TRSR). We examined the distribution of wetlands across this region based on remote sensing image interpretations. The results revealed

The oriental river shrimp (Macrobrachium nipponense), an exotic species, has been well adapted and dispersed in Iranian freshwater ecosystems. The feeding ecology and trophic level of this species in the Anzali Wetland, southwestern Caspian Sea, was investigated by both a traditional method and the carbon and nitrogen stable isotope technique. The highest feeding index (FI) was seen in mollusca at

Earth hummocks are widely distributed in arctic, sub-Arctic and alpine regions and have important roles in determining plant diversity and the nutrient content of soils. We investigated the impact of the spatial heterogeneity on soil properties and plant communities caused by the hummocks on the Tibetan Plateau. The results indicated alpine hummocks created higher plant diversity and soil fertile island

Habitat heterogeneity in the Pantanal results from flood dynamics and vegetation characteristics. Considering that these impacts affect landbird nesting conditions and food resource availability, species turnover and richness should respond to them. We conducted this study in the northeastern Pantanal, in two dominant habitats, savanna and forest, covering two annual cycles. The objectives were: (1)

As sea levels rise, coastal wetlands are encountering physical barriers to inland migration in a phenomenon known as “coastal squeeze.” Specifically, wetlands are being squeezed between sea-level rise on one side and human development on the other preventing their natural ability to adapt by moving to higher ground. State and local coastal governments have legal and policy tools available to adapt

Despite their high diversity and degree of endemism in the southeastern US, little is known about population genetic structure of most crayfishes. This is because of their cryptic morphology and elusive behavior, particularly burrowing species. We compared population genetic structure of 2 burrowing crayfish species (Creaserinus burrisi and C. byersi) from bogs in Washington, Baldwin, and Mobile counties

In early successional stages, seedlings serve as a link between past and future wetland plant assemblages. Our objectives were to 1) enumerate seedling density in soil exposed to various hydrologic treatments 2) determine similarities between standing vegetation, germinated seedlings, and early successional stage assemblages, and 3) better understand effects of landscape-level factors on overall wetland

Integrated Constructed Wetlands (ICWs) are potentially effective tools in the effort to restore aquatic ecosystems, and also they incorporate multiple co-benefits. An ICW was constructed in Norfolk, UK, to address the degradation of a stream and lake receiving treated effluent from a small Sewage Treatment Works (STW). Results demonstrated that: (1) nutrient concentrations significantly reduced from

Scientific evaluation of tourist satisfaction could contribute to the sustainable development of wetland ecotourism. With the development of Web 2.0, online travel reviews increase significantly which provide valuable information for evaluating tourist satisfaction. Hence, this study aims to evaluate the tourist satisfaction of wetland ecotourism in Zhalong National Nature Reserve (ZNNR) based on online

Macroinvertebrate and fish metrics are an essential tool in freshwater biomonitoring. Yet, many well-known stream metrics do not perform well as indicators of anthropogenic stress in lakes and wetlands, and there is a need to better understand the role of potential confounding factors such as latitude or environmental variables acting at regional scales. We attempt to untangle the relationships among

Habitat destruction caused by human activities is threatening wetland plants. Based on Landsat 5 TM, Landsat 8 OLI, and Google Earth images, we analysed the spatiotemporal dynamics of plant populations in a degraded wetland in the Minjiang River Estuary from 2009 to 2019. Field survey records, tasselled cap transformation, and supervised classification were used for the image interpretation. The results
