A study of the pathology, epizootiology and toxicology of Streptococci found causing mortality in tilapia
(1995)
A streptococcal disease affecting hybrid tilapia (Tilapia nilotica x T aurea) at a commercial aquaculture facility in central Texas was investigated. The causative agent was identified as a biotype of Streptococcus iniae, ...
Anodonta grandis as a potential new species for freshwater aquaculture
(1995)
A series of experiments was conducted to test the suitability of the freshwater mussel Anodonta grandis as a candidate species for aquaculture in the Dominican Republic. Polyculture experiments with the freshwater prawn ...
A conceptual modeling framework and methodology for systems technology application in applied ecology
(1992)
A general framework and methodology for modeling ecological management systems was proposed, with which useful information about the system, in varied forms, could be captured and utilized. These information dimensions of ...
Genome size evolution in the class Mammalia
(1992)
In this study, intra- and interspecific genome size variation was assessed among species within the Order Chiroptera. Outgroup taxa from the Orders Dermoptera and Primates also were examined. This study additionally addressed ...
The relationship of macrobenthic prey avaliability to shorebird use of blue-green algal flats in the upper Laguna Madre
(1994)
Shorebirds were censused and macrobenthic invertebrates sampled biweekly on two blue-green algal flats in the upper Laguna Madre from October 1991-October 1993. Twenty-two species of shorebirds were observed. Abundances ...
Status of environmental education in Texas public schools, Education Service Center, Region X
(1995)
This 1994 study investigated fifth grade teachers in Texas public schools located in Education Service Center, Region X. Response rate was 38% (316 of 836 potential respondents). Sampling error was +/- 4% at the 95% ...

(1995)
Morphological, biochemical, and molecular studies of cellular
Variation in the chromosomes of five species of pocket gophers in the genus Geomys as detected by differential staining, and the phylogenetic implications
(1992)
Two isolated populations of pocket gophers were discovered outside the previously known distribution of geomyids in Texas. These represent a new taxon, which is related to Geomys texensis in biochemical properties, chromosome ...
Temporal genetic structure and energy dynamics of an intergrade largemouth bass population
(1993)
This study evaluated the temporal genetics and energy dynamics of an intergrade largemouth bass population in Aquilla Lake, Hill County, Texas. Frequencies of alleles associated with Florida largemouth bass Micropterus ...
Molt and bioenergetics of Pacific black brant (Branta bernicula nigricans) on the arctic coastal plain, Alaska
(1993)
I examined feather molt and bioenergetics of nonbreeding and failed-nesting Pacific Black Brant near Teshekpuk Lake, Alaska. Molt initiation primarily occurred during the first week in July but extended from 26 June through ...
