Growth in length and weight of three species of Sphagnum (S. fuscum, S. magellanicum and S. fallax) was studied in a glasshouse experiment. The Sphagnum mosses were cultivated at natural density on cores of five different peat types, representing a grad ...
This paper presents the development of a practical tool to evaluate the required width of a hydrological buffer zone, in order to maintain the effects of subsurface drainage within reasonable limits. A simple mathematical formulation describing the lateral ...
The spatial and temporal processes of secondary vegetation development on abandoned cutover bog surfaces in the Jura region of northwest Switzerland have been examined. Descriptions of post-abandonment development of peatland based on the vegetation compos ...
Vegetation responses to environmental gradients in peatlands are well documented but little is known about how these patterns compare with those of soil organisms. We studied the vegetation, testate amoebae, and abiotic variables (depth of the water table ...
Stratigraphy, radiocarbon dating and analyses of pollen, plant macrofossils and testate amoebae were used to reconstruct the development and ecology of a small raised bog in a karst-dominated landscape in the Swiss Jura Mountains. Special focus was on past ...
Testate amoebae (Protozoa) living in Sphagnum peatlands are important environmental and paleoecological indicators. The distribution of these animals is closely related to soil moisture variables. This study examines the ecology of sphagnicolous testate am ...
The sampler extracts uncompressed cores of 13.3 cm in diameter, up to 70 cm long, from the surface layers of peat. It has two close-fitting concentric cylindrical tubes, the outer one acting as a cutter and the inner one as a collector. As the outer tube i ...
A description of the bog-pine (Pinus uncinata var. rotundata) dominated vegetation of uncut oligotrophic mires affected by drainage is given. Surveys were carried out at 17 sites along the Jura Mountains (Switzerland and France) in 1993, 1994, and 1995. Ra ...
