Summer hydroclimatology of an extensive low-gradient wetland: Polar Bear Pass, Bathurst Island, Nunavut, Canada

Polar Bear Pass (PBP) (75°40′N, 98°30′W) is considered a critical wetland area for migratory birds, caribou and muskox. Little is known of its climatology and hydrology. Here we evaluate both the short-term and long-term summer climatic record for this wetland. A 10 m high automatic weather station (AWS) was established here 27 years ago, and in 2007 this centrally located AWS was supplemented by ...

Microbial degradation of N-methyl-2-pyrrolidone in surface water and bacteria responsible for the process

Due to widespread utilization in many industrial spheres and agrochemicals, N-methyl-2-pyrrolidone (NMP) is a potential contaminant of different surface water ecosystems. Hence, investigation was made into its aerobic microbial degradability in samples of water from a river, wetland area and spring. The results showed that the compound was degradable in all water types, and that the fastest ...

Copper and nickel effects on survival and growth of Northern Leopard Frog (Lithobates pipiens) tadpoles in field‐collected smelting effluent water

Trace metals can have subtle, yet chronic impacts on organisms by inducing physiological stress that reduces their survival or impedes their ability to tolerate additional environmental stressors. However, toxicity literature indicates that aquatic organisms react differently to trace metals depending on the environments in which they reside. The objective was to understand the response of ...

Comparison on soil organic carbon within two typical wetland areas along the vegetation gradient of Poyang Lake, China

Poyang Lake is an important wetland with international significance in biodiversity conservation and local carbon cycle. A study was conducted to investigate the effects of vegetation communities on seasonal and spatial variations of soil organic carbon (SOC) and dissolved organic carbon (DOC) in two dominant wetlands (dish-shaped pit wetland and delta wetland) of Poyang Lake, China. Results ...

Factors Influencing Mercury in Freshwater Surface Sediments of Northeastern North America

We report on an inventory and analysis of sediment mercury (Hg) concentrations from 579 sites across northeastern North America. Sediment Hg concentrations ranged from the limit of detection ca. 0.01–3.7 g g–1 (dry weight, d.w.), and the average concentration was 0.19 g g–1 (d.w.) Sediment methylmercury concentrations ranged from 0.15 to 21 ng g–1 (d.w.) and the mean concentration was 3.83 ng g–1 ...

Integrated Constructed Wetlands: concept, design, site evaluation and performance

'Integrated Constructed Wetlands' (ICW) are a joined-up approach to land and water management. Significant synergies were achieved by explicitly combining environmental, ecological and aesthetic objectives. Intercepted precipitation was found to be the main factor determining treatment efficacy. Soil infiltration and evapo-transpiration combined to enhance hydraulic residence time. A wetland area ...
