We explored N2 fixation and alkaline phosphatase activity (APA) in periphyton from a N-limited stream ecosystem by coupling measurements of these processes with nutrient diffusion substrata (NDS)...

The littoral regions of Guntersville Reservoir have a long history of nuisance infestations of Myriophyllum spicatum (Eurasian watermilfoil) and more recently of Hydrilla verticillata (hydrilla),...
In this study I quantified planktonic and community metabolism of the upper mixed zone along the riverine-lacustrine gradient in four Texas reservoirs from May 2005 to March 2006. Planktonic...

While intensified nutrient limitation of periphyton has been reported along wetland nutrient-depletion gradients, changes to the specific nutrient that limits periphyton growth are not documented. In...
Effects of drawdowns and dessication on tubers of hydrilla, an exotic aquatic weed (2001)
Robert D. Doyle, R. Michael Smart
Subterranean turions (tubers) of hydrilla lose viability when desiccated. Experimental data showed that freshly collected tubers had a moisture content between 50 and 60% and more than 90% viability....

Aquatic plant species that form dense floating canopies or mats at water surface often negatively impact the ecological and economic values of a water body. In Guntersville Reservoir, this growth...
Establishing Native Submersed Aquatic Plant Communities in Southern Reservoirs. (1998)
Smart, R. M., Doyle, Robert D., Madsen, John D., Dick, Gary O.
Some reservoirs appear to remain turbid and unvegetated for many years, while others develop extensive macrophyte communities and are much clearer. In fact, ecological theory has long recognized the...
