Variation in benthic community structure: the role of the macroenvironment along a downstream gradient.
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, ...
Land acquisition in Coryell County, Texas, for the formation of Camp Hood, 1942-45 : a civilian perspective.
This thesis examines the acquisition of land in Coryell County, Texas, for the formation of Camp Hood during the years 1942 through 1945. It focuses on the effects that event produced on property owners who surrendered ...
The effects of phosphorus starvation on phosphate storage, three storage products and cellular organelles of Chlorella pyrenoidosa.
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 effect of the form and concentration of nitrogen on geosmin production by an aquatic actinomycete (streptomyces isolate WM1C1).
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 Austin chalk and its petroleum potential : South-Central Texas
The Austin Chalk Formation (Upper Cretaceous) consists of uniformly bedded lithologies throughout south-central Texas. The lithologies found within the subsurface are technically wackestones to mudstones. These general ...
The role of zooplankton - phytoplankton community interactions in the nutrient dynamics of Lake Chapala, Mexico.
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 ...
Biological nitrogen fixation in a nitrogen limited tropical lake, 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 ...

Fannie Coddington was born in New York on September 6, 1853. Her father, Thomas B. Coddington, was a wealthy metal merchant with locations in both New York and London. In 1868, Fannie moved with her family to London ...
Phytoplankton productivity of tropical Lake Chapala, Mexico.
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 ...
