Approaches to wildflower meadow establishment
Several aspects of wildflower meadow establishment using native Virginia herbaceous perennial species were investigated. The initial task lay in identifying the truly native species from those European introductions which have successfully naturalized in the state. Germination testing was conducted …

Turbulence structure of a model seagrass meadow
… study of the hydrodynamics of a seagrass meadow was conducted to investigate the effect of water depth and velocity variations during a tidal cycle on the mean and turbulent velocity fields in and above the vegetation layer. The principal goal was to characterize the turbulence structure …

Grazing and Climate Effects on High Elevation Meadow Resources
… grazing and climatic gradients in high-elevation meadows. The methods include both on the ground and remotely sensed tools, and the correlations between them are assessed. The results suggest that field determined phenology, phenocam Green Chromatic Coordinate (GCC), Phenocam Normalized Difference …

Exploring connections between seagrass ecosystem services and meadow hydrodynamics
Meadows of aquatic vegetation, such as seagrass, modify the flow of water and transport of sediment in the environment. The hydrodynamic drag generated by a seagrass meadow contributes to the numerous ecosystem services it provides, which includes quiescent habitat for other species, wave damping, …

Created Ponds as Indicators of Restored Sierra Nevada Meadow Hydrology
… has led to extensive restoration of wet-meadow systems in the Sierra Nevada. Pond-and-plug restoration reconnects the stream with its historic floodplain and dams eroded gullies, which then fill with water, creating a series of ponds. Elevated groundwater tables and stream flooding return …

Hydrologic Response to Conifer Removal from an Encroached Mountain Meadow
<p>Meadows in the Sierra Nevada Mountains are an important ecological resource that have degraded in quality and distribution due to several environmental and anthropogenic stressors. The encroachment of conifers beyond forest meadow ecotones is largely responsible for the decline of meadow habitat …

Carbon fluxes of an extensive meadow and attempts for flux partitioning
In times of climate change and increasing carbon dioxide concentrations, three questions arise for ecosystem sciences: At first, which ecosystems can contribute to mitigate those processes? Secondly, how will ecosystems react on the changing conditions? And finally, is the performance of our …

A theater and amphitheater for chamber music on a mountain meadow
… music, upon a beautiful site-- a mountain meadow. The site, context and program which serve as a starting point for the new design are based on a real site and context: that of an existing center for chamber music, situated high in the mountains, housed in the buildings of an old estate. In …

Sedge/Grass Meadow Restoration on Former Agricultural Land: Analysis of Establishment Success
Sedge/grass meadow wetland restoration was conducted at three study sites located in about 4 ha of agricultural land recently acquired by New York State Department of Environmental Conservation (NYSDEC) adjacent to West Creek at its confluence with Braddock Bay in Hilton, Monroe County, New York. …

The nutritonal ecology of meadow voles (Microtus pennsylvanicus) under differing environmental conditions
… gastrointestinal morphology and physiology in meadow voles (Microtus pennsylvanicus) were investigated. Voles were randomly divided (10 in each group) and placed in 15-day treatment regimes [cold (5 C) and warm (21 C), daylengths long (18L:6D) and short (6L:18D), and diets of high fiber (50% …

Vegetation-environment relationships in a subalpine wet meadow and a brackish tidal marsh
… in the Squamish estuary and asubal pine wet meadow in Garibaldi Park in southwestern British Columbia. Vegetation abundance, soil variables, and ground elevation data were collected from 225, 0.5 X 0.5 m quadrats systematically located at five metre intervals in a 40 X 120 m sampling grid in …

Hydrologic Response to Conifer Removal and Upslope Harvest in an Encroached Montane Meadow
<p>Meadows are crucial components to larger river watersheds because of their unique hydrologic and ecological functions. Due to climate change, over grazing, and fire suppression, conifer encroachment into meadows has accelerated. In some western regions, nearly half of all meadow habitat has been …

Influence of increased sediment exposure on suspension-feeder assemblages in a temperate seagrass meadow
… research was conducted within Posidonia sinuosa meadows near Woodman Point (32◦7’S, 115◦44’E), south of Fremantle, Western Australia. At this location, persistent sediment plumes from a cement manufacturer’s wash plant provided an opportunity to study the mechanisms through which increased …

Estimating and Modeling Transpiration of a Mountain Meadow Encroached by Conifers Using Sap Flow Measurements
<p>Mountain meadows in the western USA are experiencing increased rates of conifer encroachment due to climate change and land management practices. Past research has focused on conifer removal as a meadow restoration strategy, but there has been limited work on conifer transpiration in a …

An Investigation into the successful establishment of a hay meadow community on clay capped landfill.
… to what extent the established principles of hay meadow creation are transferable to clay capped landfill. This thesis considers the creation of a hay meadow community and focuses on three properties that are influential in their development and that can be manipulated in experimental conditions: …
