Seminar in Ecology and Evolution. This course is designed to provide students in the graduate program a chance to explore current ecological and career development issues through readings of the current primary literature and through group interactions. When teaching this course, I have attempted to find a topic upon which the semester's activities can be organized. Some of the sessions of this course I led have been organized around (1) ecology of the natural communities of the Upper Midwest; (2) scientific writing, including journal articles, grants, manuscript reviews; (3) ecology of the natural communities of the Niagaran Escarpment

Plant Taxonomy. This course is designed to teach the tools required to identify and locate the vascular plants. By the end of the term students were expected to (1) master the major phylogenetic classifications of vascular plants and the methods used to arrive at these conclusions; (2) understand how taxonomic keys and glossaries can be used to identify individuals to their correct species or subspecies; (3) learn the herbarium and research skills needed to curate specimens; and (4) be able to use various tools to predict and locate new populations for a given species. 

Introduction to Environmental Science. This course serves as an introduction to the many and varied scientific fields which constitute the natural sciences. In my approach to this subject material, the first third of the class overviews the major attributes of the abiotic world which influence life, including geology, water, air, soil, and the cycling of nutrients. The second third of the class considers the major biological processes which effect life including evolution, population dynamics, species interactions, community dynamics, and food webs. In the last third, I considered in-depth two environmental crises facing the planet: (1) agriculture, and (2) biodiversity. Each of these sections was be prefaced by an introduction from popular media sources, and given the previous course content the accuracy of these messages were then critiqued. Major innovations included a home page for this class that was placed on the Web that included the course syllabus, lecture notes from each day's presentation, and test answer keys.

Fundamentals of Ecology / Principles of Ecology.  This course introduces students to the basic underlying principles of ecological theory and research, ranging from genetic to global scales of analysis. Upon completion of this course, students should be able to appreciate the natural world, including the great diversity of species and the multiplicity of their adaptations, understand how ecosystems work so as to be better able to predict the likely impacts of human activity, and be able to use ecological principles to evaluate the validity of popular ecological messages and theories. Subjects treated include: (1) population genetics and evolution; (2) population dynamics of single species; (3) relationships of organisms to their physical environment; (4) the interactions of populations of different species; (5) the dynamics of communities; (6) flow of energy and nutrients through ecosystems; and (7) factors that influence the distribution of the major terrestrial and aquatic biomes. 

Ecological Methods and Analysis. This course introduces students to modern ecological sampling and statistical techniques. Students choose a research project for the term in which they will (1) construct a bibliography of relevant primary sources for their research project; (2) write a review paper based on these primary articles; (3) write a research proposal, describing the scientific rationale and methods for their project; (4) conduct field research and analyze results; and (5) summarize those findings in the form of a scientific paper and poster. 

Conservation Biology. This course is the linear descendent of 362-471 and 362-472. In it students are taught both important ecological principles underlying conservation biology as well as the management and policy decisions which can be drawn from them. Topics to be covered include: (1) the patterns, measurement, and mechanisms underlying biological diversity; (2) the measurement of genetic diversity and its importance in species conservation; (3) the techniques used to identify community patterns and dynamics; (4) disturbance ecology; (5) the ecology of fragmentation and isolation, (6) optimum reserve design and management; (7) ex-situ conservation and reintroductions; (8) community restoration; and (9) effect of global/regional change on reserves. The course will be capped by a weekend trip to northeastern Iowa and southwestern Wisconsin to observe these principles in the field.

Biological Resource Management I. This course provides students with the important ecological principles which underlie the conservation of biological resources, including: (1) the nature of biological diversity and the effect which modern society has played on it; (2) the patterns, measurement, and mechanisms underlying biological diversity; (3) the measurement of genetic diversity and its importance in species conservation; (4) the techniques used to identify community patterns and dynamics; (5) the cycling of energy and nutrients through ecosystems; (6) disturbance ecology; (7) landscape patterns and processes; (8) the ecology of fragmentation and isolation, and (9) processes and patterns of cultural biological diversity. 

Biological Resource Management II. This course follows up 362-471, and considers the management and policy decisions which can be drawn from the basic ecological principles presented in the first semester. Major topics include: (1) optimum reserve design; (2) optimum reserve management; (3) ex-situ conservation and reintroductions; (4) community restoration; (5) effect of single-species management on reserves; and (6) effect of global/regional change on reserves. Students were then expected to apply the principles/ideas presented during the first 1½ semesters in a management plan a real Wisconsin area of biological interest. Reports enumerated the current biodiversity resources of the area, the threats faced to that diversity, the steps currently being taken to minimize these threats, and student critique of these steps, including recommendations on optimum management strategies.

Mexican Tropical Ecology. This course is centered around a 10-day trip to the northern limit of tropical forest communities near Ciudad Victoria in northwestern Mexico. Most of the time was spent at the Los Cedros and Canindo field stations operated by the Universidad de Tamaulipas and the Government of Tamaulipas. Time was also spent on Cerro Potosi near the town of Galeana. Prior to the trip, the class overviewed the scientific literature concerning the major communities (Tropical Thorn Scrub, Tropical Deciduous Forest, Cloud Forest, Oak-Pine Forest, Chaparral, Gypsum Outcrops, Spruce-Fir Forest, Alpine Tundra) and animal groups (fish, reptiles, amphibians, birds, mammals) to be encountered. 

Land Snail Taxonomy and Ecology. Participants in this course assist me in processing samples collected for analysis of land snail community structure. Students have helped process more than 300 samples collected from central Iowa to central New York state. Two students from this course have co-authored papers which are currently in submission.
