Continuing Studies Of Water Quality In Farmington Bay And The Great Salt Lake, Utah, Wayne A. Wurtsbaugh
Continuing Studies Of Water Quality In Farmington Bay And The Great Salt Lake, Utah, Wayne A. Wurtsbaugh
Wayne A. Wurtsbaugh
For the past three years, an Aquatic Ecology Practicum class at Utah State University has conducted research examining the limnology of Farmington Bay. In 2000, our class discovered that Farmington Bay could be classified as hypereutrophic, and had significantly higher levels of chlorophyll and phytoplankton than the Great Salt Lake proper (Marcarelli et al. 2001). In 2001, individual student projects identified high phosphorus loading into Farmington Bay from surrounding sewage treatment plants, brine shrimp biomass five times lower than in the Great Salt Lake, and that the water in the bay lost all oxygen on a windy night in October …

Effects Of The Frog Eleutherodactylus Coqui On Invertebrates And Ecosystem Processes At Two Scales In The Luquillo Experimental Forest, Puerto Rico, Karen H. Beard
Karen H. Beard
Determining the ubiquity of top-down control effects of predators on their prey and ecosystem processes is important for understanding community and ecosystem-level consequences that may result from predator loss. We conducted experiments at two spatial scales to investigate the effects of terrestrial frogs (Eleutherodactylus coqui) on aerial and litter invertebrates, plant growth and herbivory, and litter decomposition. At both scales, frogs reduced aerial invertebrates and leaf herbivory, but had no effect on litter invertebrates. At the smaller scale, frogs increased foliage production rates, measured as the number of new leaves and new leaf area produced, by 80% and decomposition rates …
