McKittrick Creek, a discontinuous mountain-desert stream in Guadalupe Mountains National Park, Texas, was sampled at discrete 1 ocations(pools ) to test for differences among biomass, density, species diversity, equitability, ...

Actinomycetes are organisms that produce geosmin which is one of the organic compounds responsible for the earthy (musty) odor in water. This study was designed to isolate an actinomycete, confirm it as a geosmin ...

The ultrastructure of phosphorus starved, phosphorus restored and total nutrient cells of Chlorella pyrenoidosa was described by i morphometric analysis. The rate of phosphorus incorporation into polyphosphate bodies ...

The relationship between water turbidity and bacterial cell synthesis, specific production and bacterial productivity was investigated in a small Texas reservoir. Sampling dates were selected to include a variety of ...

I investigated ammonia nitrogen (NH^-N) regeneration and grazing by zooplankton and their effects on phytoplankton production and biomass. Two sets of experiments were conducted on samples from Lake Chapala, Mexico ...

The objective of my study was to quantify the rate of biological nitrogen fixation in Lake Chapala, Mexico. Lake Chapala is the largest lake in Mexico. It is an ancient, tropical lake which is shaped in an east-west ...

Phytoplankton productivity and other environmental variables were measured for one year (June 1983 - June 1984) at five stations on Lake Chapala, Mexico. Contrary to expectations, productivity in this shallow, tropical ...
