Studies of surface-water pH and bryophyte assemblages in 440 plots from five peatland regions across northern North America reveal a very distinct, two-fold division into fens with a pH mode at 6.76-7.00, in which Amblystegiaceae are prominent, and b

Exposure to parental depression and anxiety is known to heighten the risk of internalizing symptoms and disorders in children and adolescents. Ample research has focused on the influence of maternal depression and anxiety, but the contribution of psy

Frullania selwyniana Pearson was historically recorded from only two localities in Minnesota, and was last seen in 1925. The species became listed on the Region 9 Sensitive Species List (USDA Forest Service 2007) as it is a North American endemic and

Summary 1 Groundwater‐peatland interactions were assessed by a regional survey in the Hudson Bay Lowlands, where the rapid rate of isostatic uplift has perturbed hydrological flow systems across a 6000-year chronosequence. 2 A 24 000 km 2 study are

The structure and level of water tariffs have a great impact on the poor – as well as on the sustainability and coverage of water utilities. This article explains how, and suggests that subsidies n...

Peatlands often have readily apparent gradients of plant species distributions, biogeochemistry, and hydrology across several spatial scales. Many inferences have been drawn about the colinearity of these gradients, and these assumptions have become

The most important environmental gradients of Maine peatlands are geologic substrate and alkalinity. Other gradients are coastal-inland climate, moisture content of the peat, P and K concentrations, and shade. Abundance weighted means of pH, Ca, and

The hitherto longest found lake sediment sequence on Byers Peninsula, Livingston Island, South Shetland Islands, was analysed with respect to lithology, chronology, diatoms, Pediastrum, pollen and spores, mosses, mineralogy, and sediment chemistry. D
