Piston corers for peat and lake sediments
Two pistons corers are described which are successful in cuting the wood or undecomposed fibrous peat that characterizes many peat deposits. These modified corers are equipped with a serrated cuttingExpand

THE RESPONSE OF VEGETATION TO CHEMICAL AND HYDROLOGICAL GRADIENTS IN THE LOST RIVER PEATLAND, NORTHERN MINNESOTA
SUMMARY (1) Two peat mounds have developed in the Lost River peatland of northern Minnesota. One has the chemical and physical properties of an extremely rich fen and the other has the properties ofExpand

Raised bogs in eastern North America - regional controls for species richness and floristic assemblages
The vascular flora of 65 raised bogs was determined across climatic gradients in eastem North America. The major geographic patterns in species richness and floristic composition were analysed usingExpand

Groundwater flow in a bog- fen complex, Lost River peatland, northern Minnesota.
(1) The hydrogeology of a spring-fen mound, water track, and raised bog in the remote Lost River peatland, northern Minnesota, was investigated by measurements of the groundwater levels and chemistryExpand

Raised bogs in eastern North America: transitions in landforms and gross stratigraphy
A regional survey of 60 raised bogs was made in eastern North America to determine the geographic patterns of bog landforms and gross peat stratigraphy. Three major types of bogs were identified: (i)Expand

Tectonic drivers for vegetation patterning and landscape evolution in the Albany River region of the Hudson Bay Lowlands
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 aExpand

Climate-driven flushing of pore water in peatlands
NORTHERN peatlands can act as either important sources or sinks for atmospheric carbon1,2. It is therefore important to understand how carbon cycling in these regions will respond to a changingExpand

Regional linkages between raised bogs and the climate, groundwater, and landscape of north-western Minnesota
1 Landsat imagery was used to map the distribution of 127 raised bogs in northwestern Minnesota. Bogs collectively cover 1236 km2 (16% of the study area) despite the relatively dry regional climateExpand

The Development of Streamlined Bog Islands in the Continental Interior of North America
Boreal peatlands within the interior of North America have developed vegetation landforms that simulate the shape of geologic landforms, such as islands and river channels. The genesis andExpand
