摘要:Abstract(#br)Screening of potential pollutants in surface sediments revealed that almost all persistent organochlorine pesticides were not detected in the newly flooded Mesopotamian wetlands of southern Iraq. This observation suggests that there has been minimal input of org...

摘要:Abstract(#br)Isotope and elemental composition of carbon (C) and nitrogen (N) as well as its mass loss were measured for Sphagnum fuscum litter after one and two years of incubation in three different soil zones defined by the position of water table in a pristine Sphagnum -...

摘要:Non-directional re-flooding of the wetlands in southern Iraq, which were extensively drained during the 1990s, started in 2003. The change in species composition and abundance of rotifer and cladoceran communities together with their abiotic environment were studied for 15 m...

摘要:Abstract(#br)Vegetation, testate amoebae, and metal concentrations in water and soil (mostly peat) were studied in two copper-rich treed swamps located north of Sackville, New Brunswick, Canada. One of the sites is partly disturbed, characterized by bare soil nearly devoid o...

摘要:Abstract(#br)We report natural abundance of 15 N content in a suite of plants and lichens from a sloping open peatland in coastal northern British Columbia, Canada. A wide range of δ 15 N values varying between −11 and +3‰ were observed in the studied species. Herbs, mo...

摘要:The relationship between vegetation gradients and temporal variation of groundwater table depth, groundwater pH and electrical conductivity was studied in Bekanbeushi peatland, northern Japan. These environmental factors were expressed using four statistical parameters: maxi...

摘要:Abstract(#br)Testate amoebae (Protozoa) were studied in spring, summer, and fall from the same microhabitats in a small Sphagnum -dominated peatland in southern Ontario, Canada. A total of 32 sampling stations were established in two wetland plant communities, 19 in an open Erica...

摘要:Abstract.(#br)Knowledge about the biodiversity of Canada’s vast peatlands is poor largely because peatlands have not been routinely differentiated from other types of habitats. Plants are better known than the animals. Systematic surveys of peatland plants began in the late ...

摘要:Abstract(#br)A vast ecosystem of wetlands and lakes once covered the Mesopotamian Plain of southern Iraq. Widespread drainage in the 1990s nearly obliterated both components of the landscape. This paper reports the results of a study undertaken in 1972–1975 on the vegetation...

摘要:Abstract(#br)A multi-proxy paleolimnological record obtained from a small, lowland closed-drainage basin located in the Peace-Athabasca Delta (Alberta, Canada), 10 km northwest of the present-day shore of Lake Athabasca, captures evidence of pronounced hydroecological change...
