Dr. Glenn C. Kroh
My research focus in on the differentiation of Ponderosa and Jeffrey Pine species at the genetic level
I teach the following course in the Department of Biology
Economic Botany (30233) Explores the importance of plants to human life on earth as we know it, past, present and future Section one: Review of the plant kingdom, origins of agriculture, fruits and nuts of tropical and temperate regions, grains and forage grasses, legumes Section two: Leaves, stems, and roots; spices, herbs, and perfumes; hydrogels, latexes, and resins; medicinal plants; psychoactive drugs and plant poisons Section three: Stimulating beverages; alcoholic beverages; oils and waxes; fibers, dyes, and tannins; wood, cork, and bamboo; ornamental plants Text: Economic Botany: Plants in Our World 4th Edition, McGraw Hill Press, 2014 by Simpson and Ogorzaly
Plant Biology (30504) A survey of Plant Biology including cells and tissues; roots and soil; stems and leaves; flowers, fruits and seeds; metabolism, reproductive strategies, and evolution of plant form and function; plant genetics, ecology;the importance of plants to civilization. Section one: Nature of life, cells, tissues, roots and soil, stems, leaves, flowers, fruits and seeds, water dynamics in plants, plant metabolism Section two: Growth, reproductive cycles, breeding and propagation, evolution; taxonomy and classification, bacteria and viruses, Protista, fungi Section three: Bryophytes, ferns and relatives, gymnosperms, angiosperms, flowering plants and civilization, plant ecology, biomes as related to plants Text: Stern’s Introductory Plant Biology 12th edition, McGraw Hill, 2011 by Bidlack, J.E. and Jansky, S.H.
Natural History (30613) This course addresses the history of earth and its biogeography. Included are the formation of earth and why it is unique in our solar system; the evolution of life through the present; how plants and animals evolved in the earth’s biomes as a function of continental drift, changing climate, and migration patterns; structure and function of ecosystems in North America; and finally, the biogeography of Texas
Plant Systematics (30703) Instills the ability to have a working knowledge of the taxonomy, nomenclature and evolutionary relationships among taxa of vascular plants. Introduces the expertise needed to describe and differentiate plant families. Finally, students will be able to identify and/or key out the dominant flora of the Dallas-Fort Worth metroplex Section one: Botanical nomenclature and taxonomic evidence; systematic methods and classification; floras, manuals, and botanical descriptions, tools for taxonomists, a brief history of classification; collecting and preserving plants Section two: Survey of vascular spore-producing plants; survey of gymnosperms Section three: Introduction to flowering plants; review major orders and families of dicots and monocots.

Biogeography (40313) The distribution of plants and animals on earth as a function of evolution, continental drift, and changing climate. Section one: The physical environment; biological interactions; disturbance; communities, formations and biomes Section two: Changing continents and climate; dispersal, colonization, and invasion; evolution, speciation, and extinction; realms, regions, and provinces; humans as a force in evolution and extinction Section three: Biogeographic distributions; the geography of biodiversity; and the biogeography of North America Text: Biogeography: Introduction to Space, Time, and Life, John Wiley and Sons, Inc. 2003 By Glen MacDonald I teach the following courses in the Master of Liberal Arts Program.
Ecological Principles of earth (61243) Ecology is the study of the interaction of organisms with their environment. This course will explore many aspects of the ecology of the earth. The environment includes both physical (global air patterns, soils, etc.) and biotic (competition, predation, etc.) parameters. Specifically, the course will explore the paleohistory of the earth, biomes of the world, the physical forces of today’s biosphere, the dynamics of natural communities and populations, and the global effects of man’s presence on planet earth.
The Importance of Plants in Our World (61523) Aspects of plants that make them useful to people from an economic and social perspective. The structure, chemistry, genetics and ecology of plants are examined. Products derived from flowers, seeds, fruits, stems, leaves and roots are analyzed in light of past, present and future needs of the world community.
