JENNIFER LEA BISHOP. Mapping the Boulder City Wetlands Using a Global Positioning System (GPS) and a Geographic Information System (GIS) (Under the Direction of Krystyna A. Stave and Shawn Gerstenberger) The Boulder City Wetlands is a constructed wetlands park located in Boulder City, Nevada, approximately 23 miles southeast of Las Vegas, Nevada. Currently, a baseline study of water quality is ...

Wetlands are an important natural resource in the biosphere. Traditional terms used to describe wetlands are marshes, bogs, and swamps. Early European settlers considered these areas as wastelands and did not appreciate their values. For a number of years, many of these areas were drained and used as farmland, since these lands were found to be productive. Over a 200-yr time span (1780-1980), t...

We studied patterns in avian cholera mortality, the presence of Pasteurella multocida in the water or sediment, and water chemistry characteristics in 10 wetlands at the Sacramento National Wildlife Refuge Complex (California, USA), an area of recurrent avian cholera epizootics, during the winters of 1997 and 1998. Avian cholera outbreaks (>or=50 dead birds) occurred on two wetlands during the ...

5 A constellation of saline wetlands in the Spanish Monegros Desert is currently 6 subjected to increasing agricultural pressure. Until now, no systematic study of their 7 degradation status has been performed, and no comprehensive map of these wetlands 8 has been available. Both subjects are addressed for the first time in this study. In 9 addition, we set up a conceptual tool for assessing sa...

1. Wetlands as Grazing Grounds 1.1. Wetlands and Traditional Seasonal Grazing: La Puna, Argentina–Bolivia–Chile– Peru 2. Grazing in Wetlands: Should this Threat be Prohibited? 2.1. Maintaining Biodiversity through Semi-Extensive Grazing: Palo Verde National Park, Costa Rica 3. Integrated Grazing Management in Wetlands: New Approaches 3.1. Combining Biodiversity Conservation with Livestock Reari...

We compared plant diversity in four restored and four natural wetlands in the glaciated interior plains to evaluate how quickly plant biodiversity develops following cessation of agriculture and reintroduction of wetland hydrology. After approximately ten years, restored wetlands had plot and site richness comparable to natural wetlands; 6.2 + 0.5 species per plot and 33.8 + 2.3 species per sit...

Wetlands are valuable ecosystems because they harbor a huge biodiversity and provide key services to societies. When natural or human factors degrade wetlands, ecological restoration is often carried out to recover biodiversity and ecosystem services (ES). Although such restorations are routinely performed, we lack systematic, evidence-based assessments of their effectiveness on the recovery of...

every year a large number of migratory wintering water birds, rest in the wetlands situated in the northern provinces of iran. the wetlands are very important ecosystems for these creatures. due to ecological importance of water birds, the results of this study (the birds’ populations and their changes) are helpful to monitor them and are especially important to manage the wetlands. in this stu...
