Past waste disposal practices have left large volumes of sulphidic material stockpiled in a Ramsar wetland site on the Atlantic coast southwestern Spain, leading to severe land degradation. With aim addressing this legacy issue, soil core samples were collected along two transects extending from abandoned stockpiles adjacent marshland and subjected XRD, SEM-EDS, ICP-OES ICP-MS analyses. Sulphid...

Sea level rise (SLR) poses a significant threat to shorelines and the environment in terms of flooding densely populated areas associated coastal ecosystems. Scenario analysis is often used investigate potential SLR consequences, which can help stakeholders make informed decisions on climate change mitigation policies or guidelines. However, scenario requires considerable geospatial data analyt...

In ad 1362, a major storm surge drowned wide areas of cultivated medieval marshland along the north-western coast Germany and turned them into tidal flats. This study presents new methodological approach for reconstruction changing coastal landscapes developed from site in Wadden Sea North Frisia. Initially, we deciphered long-term as well event-related short-term geomorphological changes, usin...

In response to climatic warming, eustatic sea level has been predicted to rise by about 50 cm in the next century. While feedbacks between vegetation growth and sediment deposition tend to allow marshes to maintain their morphology under a constant rate of sea level rise, recent observations of marsh deterioration suggest that changes in the rate of sea level rise may induce loss of economicall...

Abstract Freshwater wetlands are widely recognized as biodiversity hotspots for many organisms, including birds. Climate change and the projected increased risk of wetland fires may pose a major threat to in future. There is urgent need assess short- long-term effect on avian establish relevant management implications. We analysed short-term (first 3 months after fire) large (5 500 ha) spring w...

The landscape of the Mesopotamian floodplain is mainly structured by channel processes, including formation levees, meanders, scrollbars, oxbow lakes, crevasse splays, distributary channels, inter-distributary bays, and marshes. Moreover, several human-made features also form shape this landscape, such as canals, roads, trenches, farms, settlement sites ranging in size from villages to cities. ...

Abstract Many urban water bodies in Chennai, India receive untreated sewage that pollutes their waters. An example is the Sembakkam lake, which reaches Pallikaranai marshland, a proposed Ramsar site. In 2019, city experienced worst crisis 30 years, and many lakes were extremely dry, favoring peaks of heavy metals. Therefore, this study focuses on analysing metal pollution evaluating its potenti...

Abstract Segmentina nitida Müller 1774 is a rare European freshwater snail of drainage ditches and marshland, which has seen marked decrease in range (~ 80%) over the last 100 years UK. This been attributed to over-dredging for land management, conversion grazing marshes arable farmland, as well eutrophication. identified priority species UK Biodiversity Action Plan (UKBAP) that recommends furt...

Plant species establishment and survival along environmental gradients have commonly been attributed to different environmental niches, life-history and adaptive traits [1]. Effective phenotype adaptation of alder species to extreme soil conditions allows them to form canopy-closed forest vegetation on alluvial and marshland localities. Alder forests represent azonal plant communities developed...
