Riparian vegetation: Degradation, alien plant invasions, and restoration prospects
Rivers are conduits for materials and energy; this, the frequent and intense disturbances that these systems experience, and their narrow, linear nature, create problems for conservation of
Invasiveness in wetland plants in temperate North America
A review of published literature found few studies that compare the growth and dynamics of invasive populations in their new range versus those in historic ranges, but there is evidence that hydrologic alterations could facilitate invasions by Typha × glauca and Phalaris arundinacea and that increased salinity promoted spread of Typha angustifolia.
Effects of Phalaris arundinacea and nitrate-N addition on the establishment of wetland plant communities
The results demonstrate that if P. arundinacea is present, the restored sedge meadow community will not achieve levels of abundance that are possible when this species is absent, regardless of NO 3 -N enrichment conditions.
Consequences of habitat loss and fragmentation for wetland amphibian assemblages
Landscape-level variables operating at multiple spatial scales likely influence wetland amphibian assemblages but have not been investigated in detail. We examined the significance of habitat loss
Anthropogenic effects on the biodiversity of riparian wetlands of a northern temperate landscape
Land uses such as forestry and agriculture are presumed to degrade the biodiversity of riparian wetlands in the northern temperate regions of the United States. In order to improve land use decision
Riparian scrub recovery after clearing of invasive alien trees in headwater streams of the Western Cape, South Africa
Headwater rivers are the predominant kind of aquatic ecosystem in South Africa’s Cape Floristic Region. Invasion by alien woody taxa (especially Acacia longifolia and Acacia mearnsii) have altered
The Vegetation of Wet Meadows in Relation to Their Land-use
Wetland biomonitoring approaches are needed to determine when changes in response to stressors are occurring and to predict the consequences of proposed land-use changes. These approaches require an
Regional climate change adaptation strategies for biodiversity conservation in a midcontinental region of North America
Scenario planning should be an effective tool for developing responses to climate change but will depend on ecological assessments of broad enough scope to support decision-making. Using climate
Carbon Offsets as Ecological Restorations
The explosive growth of carbon markets is creating unprecedented opportunities for landscape-scale restoration worldwide. Most mandatory and voluntary greenhouse gas reduction programs allow use of
Differences in wetland plant community establishment with additions of nitrate-N and invasive species (Phalaris arundinacea and Typha ×glauca)
To explore the impacts of NO3-N enrichment, suppression by invasive species, and the interaction of these factors on restored communities, native sedge meadow communities were grew from seed in greenhouse mesocosms and subjected to NO2-N and invasive species for 4 months.
