Examining Implicit Price Variation for Lake Water Quality
… models are used to estimate implicit prices for water quality in housing markets. Recent studies aggregate sales across large spatial areas in scaled-up models leading to a concern that these models may overlook regional heterogeneity in water-quality preferences. We estimate scaled-up hedonic …

Land Use Effects On Lake Water Quality In Central Florida
Land use affects the water quality of lakes. Different land use types yield different effects due to varying amounts and constituents of runoff. In this study, the effects of surrounding land use on the water quality of 50 lakes in Seminole County, Florida was assessed. Using GIS, I placed buffers …

Assessing the influence of geological and land-use gradients on zooplankton and phytoplankton biodiversity in the land between ecotone
… The goal of this study was to investigate water quality and plankton community patterns in lakes across TLB as a function of geological and spatial drivers. Lake water quality profiles were differentiated based on calcium concentrations, and increased watershed land-use was related to …

The Roles of Local Organizations in Collaborative Resource Governance: A Qualitative Case Study of Lake Associations
… the globe are currently facing an epidemic of lake water quality degradation, primarily resulting from resource and land-use decisions that introduce excessive amounts of nutrients into the lake system. In many of these communities, local volunteer groups called lake associations work to …

The effects of lake dynamics on the water quality of Abel Lake Reservoir
The Abel Lake Reservoir in Stafford County, Virginia, was investigated to evaluate the lake's temporal and spatial dynamics with respect to water quality and water treatment problems. A limnological survey was conducted. The survey included all conventional parameters for the characterization of …

The influence of sediment nutrient dynamics on the response of lake ecosystems to restoration and climate change
… and recreation, have caused deterioration of water quality in many freshwater lakes worldwide. Apart from anthropogenic impacts, it is also recognized that climate has a direct influence on lake water temperature, nutrient loads, phytoplankton abundance and chemistry. However, little is known …

Development of bio-optical algorithms to estimate chlorophyll in the Great Salt Lake and New England lakes using in situ hyperspectral measurements
<p>Chlorophyll is widely used to evaluate lake water quality, effectively integrating the chemical, physical and biological state of a lake. Assessment of chlorophyll conditions in lakes can be greatly enhanced by the use of remote sensing, allowing information to be gathered at spatial and …

Relationships between water quality, species composition, biodiversity and ecosystem function in lakes and flooded pits exposed to uranium mining activities in Northern Saskatechewan
… and the release of treated effluent into nearby watersheds. Such anthropogenic exposure can lead to elevated concentrations of metals and major ions, which may impact aquatic biota. Previous studies have looked at the effects of water quality on aquatic biota within flooded pit lakes and natural …

Essays on Water Policy and Coupled Human and Natural Systems
Human and freshwater ecosystems are intrinsically interconnected. To better design effective policies, modeling tools and valuation methods are necessary to help understanding the complex reciprocal linkages between ecosystem processes and human actions, and coupled human and natural systems (CNHS) …

Investigating the potential of remote sensing for long-term limnological analysis at pan-continental scales
Lakes are key indicators of environmental change and major repositories of biodiversity and ecosystem services. However, studies of lake response to drivers of change at a pan-European scale are exceptionally rare. The need for such studies has been given renewed impetus by concerns over climate …

Restoring freshwater quality: an integrated environmental, economic and ecosystem services assessment of reducing nutrient loads to Lake Rotorua
The management of freshwater resources is a global concern as anthropogenic pressures on these resources have intensified. A decline in the quantity and quality of freshwater urgently requires concerted restoration actions to reverse the decline. Restoration of lakes is impacted by complex …
