The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata …

The purposes of this paper are 1) to determine the microbiotic cycles which occur in Lake Hefner in order to form a basis for ascertaining the effects of future additions of evaporation control chemicals on the biological life of this reservoir, and 2) to make a generalization as to the microbiotic cycles which might occur in Southwestern reservoirs.

Phytoplankton productivity of Lake Texoma was measured for one year from August 1999 to August 2000 for four stations, using the oxygen change method and laboratory incubation. Mean values of the photosynthetic parameters, PBmax and alphaB ranged from 4.86 to 46.39 mg O2.mg Chl-1.hr-1 for PBmax and 20.06 to 98.96 mg O2.mg Chl-1.E-1.m2 for alphaB. These values were in the range to be expected for a highly turbid, temperate reservoir. Estimated gross annual areal productivity ranged from 594 g C.m2.yr-1 (P.Q. = 1.2), at a station in the Washita River Zone to 753 g C.m2.yr-1 at a station in the Red River Zone, of the reservoir. Gross annual areal productivity at Station 17, in the Main Lake Zone, was 708 g C.m2.yr-1. Gross areal and volumetric productivity showed distinct seasonal variation with Photosynthetically Available Radiation (PAR) and temperature. Trophic status estimated on a station-by-station basis, using net productivity values derived from gross productivity and respiration estimates, was mesotrophic for all the stations, though one station approached eutrophy. Net productivity values ranged from 0.74 to 0.91 g C. m-2.d-1. An algal bioassay conducted at two stations in August 2000, revealed that phosphorus was most likely the nutrient limiting photosynthesis at both …

This thesis is an attempt to portray the part the forts of the Southwest had in developing the Federal Indian Policy in that region from 1865 to 1885.

The purposes of this research were to explore the effectiveness of the Chickasaw Nation early care and education program in promoting school readiness while infusing tribally relevant values in children from birth through age five; engaging parents in all aspects of their children’s learning; and supporting children and families through the transitioning to kindergarten. The study used qualitative methods to examine the experiences and perceptions of ten parents, ten teachers, and five administrators within Chickasaw Nation’s early care and education system regarding the four basic areas of school readiness, parent engagement, transition, and culturally relevant pedagogy. Four primary themes emerged from the semi-structured interviews: 1) socialization, school readiness, and transition, 2) learning, curriculum, and assessment, 3) the role of parents, and 4) cultural integrity. Data were collected through semi-structured interviews, transcribed, and analyzed based on four research questions. Findings indicated parents, teachers, and administrators were satisfied that the program was successful with assisting children in making progress toward achieving developmental and school readiness goals and that the children were physically, socially, emotionally, and cognitively prepared to enter kindergarten. The program provided activities to encourage and promote parental involvement; however, parents did not indicate active involvement or participation in the activities. …

The purpose of the study was to describe the use of nonfiction/informational trade books within a literature-based elementary classroom by students and the teacher. Using a qualitative ethnographic approach, the researcher became a participant observer in a third grade classroom during a two and one-half week thematic unit about the westward movement. Data were collected from field notes, audiotapes of class discussions and informal interviews, documents of students' work, photographs, daily observer comment summaries, and memos. These data were coded, analyzed for recurring patterns, and grouped together, resulting in grounded theory.

This study was initiated after finding two chromosomal types of Peromyscus maniculatus north and south of the Red River in Texas and Oklahoma. The problem was to explain the chromosomal variations and their implications to the systematics of the grassland subspecies of P. maniculatus in this region.

This investigation has been concerned with determining the extent to which a small mammal, the cotton rat, may become acclimated to environmental temperatures, and the influence acclimation has upon a population. The study was also designed to determine if acclimation effects on a population can be seen in individual rats.

The purpose of this study was to investigate the self-perceptions certified public high school teachers in the fine arts have toward their roles as artist and instructional staff member.

The purpose of the study is to determine what effect medicare has had on the distribution of public health care expenditures in the state of Oklahoma. The study tests that there is a significant correlation between medical vendor payments and indigency in Oklahoma or in other words that pre-medicare public health care dollars in Oklahoma were distributed to indigents.

Twenty-eight species of zooplankton were identified from Lake Texoma. Seasonal density of the overall microcrustacean community and seasonal cycles of individual species were compared with northern populations and any available literature from the Southwest. Cycles of occurrence and abundance were similar to those observed in northern populations but tended to occur earlier in the year due to higher temperatures. Spatial distributions within the reservoir were heavily influenced by nutrient and salt input from the Red River, which resulted in dense populations in the Red River Arm. In addition, during the summer, the microcrustacean community was restricted to the epilimnion due to anoxic conditions in the hypolimnion of the reservoir.

The purpose of this study was to determine the instructional methods of Oklahoma's elementary school music educators with respect to the inclusion of an authentic repertoire of American Indian music in the curriculum. The research was conducted through two methods. First, an analysis and review of adopted textbook series and pertinent supplemental resources on American Indian music was made. Second, a survey of K-6 grade elementary music specialists in Oklahoma during the 1997-1998 school year was conducted.

The purpose of this study was to compare four different methods of bibliographic instruction in order to determine which method would have the most effect on student learning.

This study was conducted to examine the use of microcomputers and other computers by top administrators in the twenty—seven public colleges and universities in Oklahoma; to assess the impact that training and other factors have on the extent to which microcomputers are being used; and to identify trends in administrative computer usage. The survey technique was utilized in collecting the data for this study. The survey instrument was developed for use in this study from a review of the literature, an evaluation by a panel of judges, and a pilot study. The survey instrument was sent to the administrators for business, academic, and student affairs via the president of each university in the 1986 spring and summer semesters. Seventy-four of the eighty-one or 91.4 percent of the administrators responded. Following is a summary of the major findings of this study. 1. Fourteen of the seventy-four or 18.9 percent of the respondents personally use a microcomputer and 51.3 percent of the respondents have someone use a microcomputer on their behalf. 2. The most prevalent use of microcomputers is word processing; the most prevalent uses of mainframes are word processing and database management; and the majority of the respondents do not use …
