Long fire rotation, high levels of precipitation, and acidic nature of the bedrock are factors contributing to the dominance of Sphagnum in many upland and peatland communities in southeastern Labrador. Vegetation development induced by local or regional environmental change frequently involves replacement of species assemblages of various bryophytes and lichens by species assemblages dominated...

The carbon sequestration potential of peatlands has led to increasing interest in the restoration bogs previously subjected plantation forestry. However, little information exists about effects on hydrological processes what become known as forest-to-bog restoration. functioning three afforested, two intact and four sites was compared at a raised bog blanket location. For location, annual runof...

Raised bog pools are extremely nutrient poor and rich in humic substances, and these features limit primary production. To assess the base of the invertebrate food web in bog pools we measured the stable-isotopic signatures of primary producers, dead organic matter, and invertebrates, and the composition and stable-C-isotope ratio of their phospholipid-derived fatty acids (PLFAs). The stableiso...

Entropy production (σ) is a measure of ecosystem and landscape stability in a changing environment. We calculated the σ in the radiation balance for a well-drained spruce forest, a paludified spruce forest, and a bog in the southern taiga of the European part of Russia using long-term meteorological data. Though radiative σ depends both on surface temperature and absorbed radiation, the radiati...

The lake and bog deposits of Cedar Creek Forest, Isanti and Anoka counties, Minnesota, consist of a multiple-facies accumulation of marl, peat, copropel, and sapropel. Chromatographic analyses of the lipoid extracts of samples of the sediments show measurable amounts of saturated and aromatic hydrocarbons as well as large proportions of asphalts and polar lipoid compounds. In general compositio...

This paper presents the distribution of the terrestrial isopod Hyloniscus adonis (Verhoeff, 1927) in croatia. It was recorded for the first time at the edge of Dubravica peat bog and the adjacent forest. Additionally, it was collected at the edges of Đon močvar peat bog. Revision of the terrestrial isopod collection of the Croatian Biospeleological Society revealed that this species also occurs...

The vegetation recovery at Kaimaumau gumland was monitored in seven permanent plots from 1988 to 1999 following a large fire in 1988 in order to determine rates and patterns of vegetation recovery. A succession profile for the key vegetation types that are currently developing is suggested. Schoenus brevifolius was the first species to colonise from rhizomes after the fire, and has remained the...

This study examined the effects of agricultural runoff on the vegetation structure of Franklin Bog, a priority conservation area located in a rapidly developing region of northwestern Vermont. Forested and agricultural runoff from the mixed land use watershed created differential vegetation patterns in the wetland, including weedy species introductions. Concentrations of nitrogen and phosphorus...
