(Texas A&M University. Libraries, 1983)Laboratory and pond research was conducted at a power plant site near the inner end of Galveston Bay, Texas. Of tested salinity levels, 25 ('o)/oo was found the best for both species to resist high lethal temperatures and ...
-
(Texas A&M University. Libraries, 1987)A series of experiments were conducted to quantify the extent to which dissemination and establishment of mesquite is enhanced by activities of domestic livestock. In the Rio Grande Plains of south Texas, dispersal of ...
-
(Texas A&M University. Libraries, 1994)The Great Lakes are surrounded by heavily industrialized regions. High frequency of hepatocellular neoplasm in fish has been found. This study was undertaken to assess the environmental contamination by analyzing polycyclic ...
-
(Texas A&M University. Libraries, 1987)The effects of various halogenated hydrocarbon pollutants on hepatic microsomal drug and steroid metabolizing enzymes were determined in neonatal, immature and adult Long Evans rats. The teratogenic and/or fetotoxic effects ...
-
(Texas A&M University. Libraries, 1977)Heat resistance times of 10 species of crustaceans representing 5 families and 65 fishes from 32 families were determined during June 1974 through September 1975 to estimate percentage survival in the discharge canal system ...
-
(Texas A&M University. Libraries, 1985)A four-part study was conducted at the Texas Agricultural Experiment Station, 56 km southwest of Sonora, Texas on the Edwards Plateau. The objective of the study was to provide a greater understanding of the hydrologic ...

(Texas A&M University. Libraries, 1977)Embryos and juveniles of the horseshoe crab, Limulus polyphemus were exposed continuously to 0, 5, 10, 25 and 50% Water-Soluble Fractions (WSF) of no. 2 fuel oil at temperatures of 20°, 25° or 30° C and one salinity, 32 ...
-
(Texas A&M University. Libraries, 1977)Seasonal occurrence, abundance and susceptibility to cooling-water operations were determined for 89 species of fish occurring in intake and discharge canals of the P. H. Robinson Generating Station on Galveston Bay, Texas ...
-
(Texas A&M University. Libraries, 1993)Environmental Protection Agency Regulations have mandated certain actions to control asbestos fiber release episodes in public school systems in the United States. These mandates do not differentiate between asbestos types ...
-
(Texas A&M University. Libraries, 1978)Agricultural production and associated economic effects of irrigation on the Texas High Plains are seriously threatened by a rapidly declining groundwater supply and a swift upward trend in energy costs. To optimize the ...
-
(Texas A&M University. Libraries, 1977)Crustacean abundance, distribution and taxonomic composition were determined intake (Tabbs Bay and Cedar Bayou) and discharge (Trinity Bay) areas before operation (October 1969 through September 4, 1970), during operation ...
-
(Texas A&M University. Libraries, 1978)Biological and hydrological data were collected once each month January 1968-December 1969 at 11 offshore (trawl) and 6 beach (seine) stations in the discharge area of the P.H. Robinson Generating Station at Galveston Bay, ...
-
(Texas A&M University. Libraries, 1978)Species composition, abundance, and distribution of macro-crustaceans and fishes in the intake area, discharge canal and cooling lake of the Cedar Bayou Electric Generating Station near Baytown, Texas, were analyzed using ...
