An Analysis of Distribution Patterns of Amphibians and Reptiles in Texas

An Analysis of Distribution Patterns of Amphibians and Reptiles in Texas

Date: August 1969
Creator: Leonard, Cuyler Hershey
Description: The purpose of this investigation was to analyze the distribution of amphibians and reptiles in Texas by means of the methods of Webb and Hagmeier and Stults. An additional graphical analysis was made, including range and range limits which provides a cross-section of faunal change along selected base lines across the state.

Anatomical and Morphological Responses of Cardiospermum Halicacabum L. (Balloon Vine), to Four Levels of Water Availability

Anatomical and Morphological Responses of Cardiospermum Halicacabum L. (Balloon Vine), to Four Levels of Water Availability

Date: May 2011
Creator: Dempsey, Matthew Anthony
Description: C. halicacabum (Sapindaceae) is an invasive plant that is considered a nuisance species in Texas riparian environments. Little is known of the tolerance of C. halicacabum to flooding and drought; however, this information may provide insight into the characteristics that contribute to C. halicacabum purported invasiveness. C. halicacabum seedlings (n = 92) were exposed to one of four levels of water availability (flooded, saturated, intermediate and dry) over six weeks under greenhouse conditions. Plant performance was affected by water availability; however, there was no effect on survivorship. Flooded and saturated plants exhibited morphological adaptations; producing adventitious roots, hypertrophy, and aerenchyma tissue. Morphological measures, anatomical responses, and patterns of biomass allocation all indicate that C. halicacabum is able to survive periodic inundation, perform in saturation, and establish and thrive on the drier end of a moisture gradient.

Anatomy and Physiology Syllabus for Community Colleges

Anatomy and Physiology Syllabus for Community Colleges

Date: May 2000
Creator: Schulz, Leslie
Description: This syllabus includes both lecture notes and laboratory activities for a two-semester anatomy and physiology community college course. The syllabus is based on a 16-week semester that is comprised of a three-hour lecture section and a one-hour laboratory class each week. Both the lecture course and laboratory are necessary to fulfill the requirement for anatomy and physiology. Laboratory activities coincide with lectures to enhance understanding of each topic by providing visual and hands-on experiments for the concepts learned in the lecture. Laboratory quizzes will be given each week to help students maintain a working knowledge of the material learned in the laboratory. This course is appropriate for the typical anatomy and physiology student and should benefit both students who plan to major in biology and also those who are non-biology majors. Because subject matter in anatomy and physiology is quite difficult, the importance of attendance and good study skills is stressed.

Animal contribution to human medicine

Animal contribution to human medicine

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Kvernes, Kayce
Description: The use of animal models in research has led to a fierce debate between animal rights activists and scientists. The former claim that little useful information is gained from animal studies and the suffering of animals does not preclude any treatments which may be used to treat human illnesses. Yet, research scientists claim that in vivo animal models are of absolute necessity to developing treatments and cures to disease. To determine the necessity of animal use, one must examine the models currently in research. Have the animal models for disorders such as cystic fibrosis and muscular dystrophy given scientists enough information to develop effective treatments? This paper will examine the role of animal subjects in several disease research protocols, as well as the applicability of the research.

Antibiocity of the Oleoresins of One Hundred Texas Spermatophytes upon Twenty Gram-Positive Bacterial Organisms

Antibiocity of the Oleoresins of One Hundred Texas Spermatophytes upon Twenty Gram-Positive Bacterial Organisms

Date: 1949
Creator: Richardson, Lavon P.
Description: This investigation is concerned with the testing, in vitro, of oleoresins from one hundred higher plants common to North and South Central Texas. The plants used were selected in order to obtain a representative collection which might be of value in future research.

The Antibiotic Activities of Some Members of the Cactaceae Family

The Antibiotic Activities of Some Members of the Cactaceae Family

Date: 1951
Creator: Gilmore, Derward E.
Description: This problem has been concerned with, first, the collection of sixteen species of plants belonging to Cactaceae family; second, the drying of these and the extraction of the oleoresins thereof; third, the determination of the extent to which these substances inhibit the growth of ten gram-positive and ten gram-negative bacterial organisms; and fourth, a determination of the possible utilization of these extracts a prophylactic or chemotherapeutic agents.

The Antibiotic Effect of Pigmented Actinomycetes

The Antibiotic Effect of Pigmented Actinomycetes

Date: 1951
Creator: Cichon, Casimir Joseph
Description: This thesis attempts, first, to correlate pigmentation of actinomycetes with the degree of antibiocity; second, to establish the most favorable means of producing a rich luxuriant pigmentation in the individual organism studied by enriching favorable media with specific types of proteins and amino acids.

The Antibiotic Properties of the Oleoresins of Twenty-Five Common Garden Vegetables

The Antibiotic Properties of the Oleoresins of Twenty-Five Common Garden Vegetables

Date: 1951
Creator: Ennis, Arthur F.
Description: The purpose of this problem is to determine the presence and extent of antibiotic materials as found in the oleoresins of a selected group of garden vegetables. The problem has consisted of, first, the collection and preparation of specimens of twenty-five commonly used garden vegetables; second, the extraction of the oleoresins from these; third, the determination of the inhibitory and other effects of these oleoresins against several strains of selected gram-positive and gram-negative bacteria; and fourth, the evaluation of the potentialities of these oleoresins with regard to their future use as medicinal prophylactics and therapeutics.
