(Texas A&M University. Libraries, 1978)Trawl collections were taken from June 1974 to September 1975 to determine the abundance and distribution of fishes in the canal system of the Houston Lighting & Power P.H. Robinson Generating Station with emphasis on ...
-
(Texas A&M University. Libraries, 1979)This study includes: 1) arrival, range expansion, seasonal distribution, and migration; 2) nesting habitats; 3) food habits; 4) reproduction; 5) population dynamics; 6) pesticide residues; 7) species interrelations; and ...

(Texas A&M University. Libraries, 1995)Morphological, biochemical, and molecular studies of cellular
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1977)Four subpopulations of Thomson's gazelle in the Serengeti National Park were designated as Serengeti Main, Loliondo, Loita, and Kirawira. Seasonal distribution of subpopulations within the Serengeti was illustrated. The ...
-
(Texas A&M University. Libraries, 1986)Habitat factors, feeding ecology, and physiological body condition of northern shovelers (Anas clypeata) were studied on saline wetlands of the Texas Gulf Coast, and on several freshwater lakes 18 km inland. The hypothesis ...
-
(Texas A&M University. Libraries, 1993)Surveys of wild populations seldom satisfy assumptions fundamental to the survey techniques used to assess them (i.e., spatial distributions tend to be nonrandom). When sample sizes (i.e., number of observations) are small, ...
-
(Texas A&M University. Libraries, 1979)Southwestern aridlands have undergone extensive changes in the broad pattern of vegetation since the mid-19th century. In West-Central Texas, woody plant species, primarily mesquite (Prosopis qlandulosa) and red-berry ...
-
(Texas A&M University. Libraries, 1978)This study of relationships between grassland birds and their resources was conducted in 1975-1976 on the plains portion of the Serengeti National Park, Tanzania. The objectives were a) to test the hypothesis that food was ...
-
(Texas A&M University. Libraries, 1989)Data collected from a commercially operated intensive shrimp farm on the Texas coast were used to evaluate certain operational aspects of penaeid shrimp farming in Texas. These data then were incorporated in a simulation ...
-
(Texas A&M University. Libraries, 1980)This study collected data on mourning doves on the Texas A&M University campus, College Station, Texas from 1978 through 1979. During this study 2,258 doves were banded and 1,620 were recaptured for a total of 3,878 ...
-
(Texas A&M University. Libraries, 1985)Small mammals of two species (Peromyscus leucopus and Sigmodon hispidus) were trapped at a locality polluted with a complex mixture of petrochemical waste products, heavy metals, and PCB's, and from two matched, uncontaminated ...
-
(Texas A&M University. Libraries, 1980)The iguanid lizard Sceloporus qrammicus consists of at least six chromosome "races" (=cytotypes) distributed throughout most of Mexico. Three of these cytotypes (2n=32, 34, and 36) were studied in detail in that part of ...
-
(Texas A&M University. Libraries, 1995)Cold resistance of blue tilapia (Tilapia aurea) was measured as the first step in development of a simulation model to predict acclimation state and mortality of tilapia exposed to varying low temperature. The model is ...
-
(Texas A&M University. Libraries, 1973)After the osteology of Cynoscion nebulosus is described in detail, three other species, C. arenarius, C. nothus and C. regalis are compared to it. The four species studied can be broken into two phyletic lines; one containing ...
-
(Texas A&M University. Libraries, 1973)The physiological ecology of eastern and western hognose snakes are compared from an interspecific competition basis. Study methods included radiotelemetry, mark-recaptures, histological, anatomical and behavioral techniques. ...
-
(Texas A&M University. Libraries, 1991)The behavior of three species of nocturnal Texas geckos, Hemidactylus turcicus. Cyrtopodion scabrum, and Coleonyx brevis, was studied in an indoor laboratory and an outdoor enclosure complex to assess the behavioral I ...
-
(Texas A&M University. Libraries, 1975)Field studies were conducted in the summers of 1972, 1973, and 1974, to quantitatively document the breeding avifaunas of 5 relict woodland communities of the southern Guadalupe Mountains, Guadalupe Mountains National Park, ...
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1979)Data on the ranges, movements, reproductive activities, and associated cover types of the Attwater's prairie chicken were collected from 1 January 1976 through 31 August 1977, on the 6,400 ha Lake Pasture of the O'Connor ...
