(Texas A&M University. Libraries, 1984)The objectives of this study were to: (1) determine which factors are contributing to the decline of the Angora goat industry in Texas, (2) determine the cost of predation to Angora goat ranchers at one specific site and ...
-
(Texas A&M University. Libraries, 1981)Estuarine fishes were cultured in cages in the intake area and at four locations in the cooling lake of a power plant near Baytown, Texas from 1 September 1976 through 1 September 1978 to determine the effects of heated ...
-
(Texas A&M University. Libraries, 1982)The impact of the Cedar Bayou Electric Generating Station upon fishes and macrocrustaceans in the intake area, discharge canal, and cooling lake during 1972-1979 was evaluated. Data used to determine relative abundance, ...
-
(Texas A&M University. Libraries, )The effects of mammalian predator control on (1) the productivity and survival of Angora goats and (2) population trends of game and nongame wild life were studied during January-July 1975 and 1976 in northern Zavala County, ...
-
(Texas A&M University. Libraries, 1983)During 1978-1983, samples of largemouth bass Micropterus salmoides were taken from 10 small impoundments (0.4 to 16.0 hectares) in north-central, south-central, and southwestern Texas and submitted to electrophoretic ...
-
(Texas A&M University. Libraries, 1983)Migration and distribution of two decapod shrimp, Penaeus setiferus and P. aztecus, in the cooling-water system of a power plant on the Texas coast were investigated, with emphasis on the seaward emigration from the cooling ...
-
(Texas A&M University. Libraries, 1982)A study was conducted to determine the nutritional status of white-tailed deer in South Texas on a monthly basis between March 1979 and April 1980. Food habits of deer were determined by examining rumens microhistologically. ...
-
(Texas A&M University. Libraries, 1981)The feasibility of polyculturing Macrobrachium rosenbergii and Tilapia aurea was examined in 500 m('2) earthen ponds in central Texas. Monoculture of each species was also undertaken to provide comparative data. Secondary ...
-
(Texas A&M University. Libraries, 1982)Subgrouping behavior of javelina populations in two brushland habitats in south Texas was examined from June 1979 through February 1981. This study was couched within an effects of hunting study framework. In each habitat, ...
-
(Texas A&M University. Libraries, 1982)A histological study of the eyestalk of the freshwater prawn, Macrobrachium rosenbergii, was conducted to characterize its neurosecretory elements. Neurosecretory cell groupings (X-organs) were associated with each of the ...
-
(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, 1982)Genetic relationships among three races of the plains pocket gopher, (Geomys bursarius complex) were determined using data from chromosome banding, meiotic analysis, and protein electrophoresis. Race E (2n = 74, FN = 72) ...
-
(Texas A&M University. Libraries, )The productivity and habitat use of Rio Grande turkeys (Meleagris gallopavo intermedia) was evaluated from May 1976 through November 1977 on the Welder Wildlife Refuge near Sinton, Texas. During the summers of 1976 and ...
-
(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, )This study was undertaken to gain an insight into the impact that dredged material islands have had on the upper Laguna Madre, Texas and the degree of ecological succession that has taken place since the creation of these ...
-
The influence of prescribed burning on nutrition in white-tailed deer on the coastal plain of Texas (Texas A&M University. Libraries, 1977)An isolated area of approximately 2,025 ha of thicketized live oak (Quercus virginiana) savannah was experimentally burned during a 2-year study on the Texas Coastal Plain. Two fall burns (October 1974 and 1975) and a ...
-
(Texas A&M University. Libraries, 1983)Temporal and spatial use patterns of 2 South Texas feedlots by wintering blackbirds were examined. Economic impact associated with daily foraging was estimated. Effectiveness of 6 selected bird-damage control techniques ...
