Influence of weather extremes on the water levels of glaciated prairie wetlands Influence of weather extremes on the water levels of glaciated prairie wetlands
Orchid Meadows is a long-term wetland research and monitoring site on the Coteau des Prairie in extreme east-central South Dakota, USA. It is a 65-ha Waterfowl Production Area with numerous temporary, seasonal, and semi-permanent wetlands. Ground water and surface water have been monitored at the site from 1987 to 1989 and from 1993 to the present. Vegetation has been monitored since...

Seasonal methane emissions by diffusion and ebullition from oligohaline marsh environments in coastal Louisiana Seasonal methane emissions by diffusion and ebullition from oligohaline marsh environments in coastal Louisiana
Methane is an important atmospheric greenhouse gas that is emitted from many natural and anthropogenic sources. In order to evaluate the global methane budget, precise data are needed from the diverse sources including coastal wetlands. Over 100 time-series determinations of methane emissions from an oligohaline wetland (brackish marsh) in coastal Louisiana show large variability during...

An integrated analysis of the effects of past land use on forest herb colonization at the landscape scale An integrated analysis of the effects of past land use on forest herb colonization at the landscape scale
A framework that summarizes the direct and indirect effects of past land use on forest herb recolonization is proposed, and used to analyse the colonization patterns of forest understorey herbaceous species in a 360-ha mixed forest, grassland and arable landscape in the Dijle river valley (central Belgium). Fine-scale distribution maps were constructed for 14 species. The species were...

Differences in distribution of modified basins and ducks relative to roadside transects Differences in distribution of modified basins and ducks relative to roadside transects
Wetland basins in the Prairie Pothole Region of the U.S. are commonly modified by excavation (e.g., roadside ditches, stock dugouts), partial drainage (ditching), and diking. Differences in the distribution of modified wetlands may affect the predictive accuracy of waterfowl survey data if such wetlands are not distributed randomly in the landscape and if waterfowl are not distributed...

Preface: Phragmites australis: A sheep in wolf's clothing? Preface: Phragmites australis: A sheep in wolf's clothing?
A. problem with national priorities for control or prevention of aquatic nuisance species is that we often do not know the full extent of the problem, if there is one. To address this issue, we hosted a technical forum and workshop-Phragmites australis: A Sheep in Wolf's Clothing?--with a focus on new research and critical reviews that address the role of Phragmites as a noxious weed....
