Book excerpt: Algal biomass in streams is influenced by a combination of bottom-up (nutrients) and top-down (gazers) effects. The objective of the current study was to investigate the relationship between snails and algal biomass through a survey and an in situ experiment. In Ozark streams, prosobranch snails are important grazers, and perhaps buffer the effects of eutrophication. During summer 2006, I surveyed eight streams in the James River watershed (Southwest Missouri) for snail density, species richness, and algal biomass. My survey showed a significant difference in algal biomass among the streams, with Wilson's Creek having the highest mean chlorophyll-a (172 mg/m2) and James River having the lowest (28 mg/m2). My survey also showed a negative correlation between snail (Elimia potosiensis) and algal biomass. A 1-month enclosure experiment was conducted in Wilson's Creek to test the relationship of snail density (zero, low, high, and ambient) on algal biomass through time. As time progressed, algal biomass decreased in all treatments. Snail density had no statistically discernable effects on algal biomass. The contrasting results from the survey and experiment may be due to high nutrient levels, which stimulate a high replacement rate of algae, and relatively low snail densities in Wilson's Creek.

This book was released on 2014-04-16 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The City of Baltimore, Maryland, and parts of five sur- rounding counties obtain their water from Loch Raven and Liberty Reservoirs. A third reservoir, Prettyboy, is used to resupply Loch Raven Reservoir. Management of the water- shed conditions for each reservoir is a shared responsibility by agreement among City, County, and State jurisdictions. The most recent (2005) Baltimore Reservoir Watershed Management Agreement (RWMA) called for continued and improved water-quality monitoring in the reservoirs and selected watershed tributaries. The U.S. Geological Survey (USGS) conducted a retrospective review of the effective- ness of monitoring data obtained and analyzed by the RWMA jurisdictions from 1981 through 2007 to help identify possible improvements in the monitoring program to address RWMA water-quality concerns.
