3.00 Credits
PQ: BIOS 10110 or 10130. This course considers the continuing erosion of the resources of the Earth by the persisting pressures of a growing human population, which makes a broad knowledge and appreciation of biology essential. Discussion includes the principles of energy conversion by plants as primary producers, the evolution of the structures and mechanisms involved in energy conversion, the origin of crop plants, improvements of plants by conventional breeding and genetic engineering, and the interactions of plants with pathogens and herbivores. M. Ruddat. Winter.

3.00 Credits
PQ: BIOS 10110 or 10130. This course emphasizes basic scientific understanding of ecological principles that relate most closely to the ways humans interact with their environments. It includes lectures on the main environmental pressures, notably human population growth, disease, pollution, climate change, habitat destruction, and harvesting. We emphasize the ongoing impacts on the natural world, particularly causes of population regulation and extinction and how they might feed back on to humans. Discussion required. T. Price. Spring.

PQ: BIOS 10110 or 10130. Ecology is the study of the distribution and abundance of organisms. This course highlights key themes in ecology (e.g., how the environment affects species, evaluating the viability of populations, the implications for interactions among species, and the function of ecosystems). Emphasis is placed on how ecological information is being applied in the area of conservation biology. C. Pfister. Autumn.

3.00 Credits
PQ: BIOS 10110 or 10130. This lecture course focuses on the ecological communities of the Southwest, primarily on the four subdivisions of the North American Desert, the Chihuahuan, Sonoran, Mohave, and Great Basin Deserts. Lecture topics include climate change and the impact on the flora and fauna of the region; adaptations to arid landscapes; evolutionary, ecological, and conservation issues in the arid Southwest, especially relating to isolated mountain ranges; human impacts on the biota, land, and water; and how geological and climatic forces shape deserts. E. Larsen. Spring.

3.00 Credits
PQ: Consent of instructor. This lecture/lab course is the same course as BIOS 13111, but includes a lab section preparatory to a two-week field trip at end of Spring Quarter, specific dates to be announced. Our goal in the lab is to prepare proposals for research projects to conduct in the field portion of this course. Field conditions are rugged. Travel is by twelve-passenger van. Lodging during most of this course is tent camping on developed campsites. E. Larsen. Spring. L.

3.00 Credits
PQ: BIOS 10110 or 10130. Third- or fourth-year standing or consent of instructor. Warm coat and ability to walk five miles required. This course looks at the Midwest prairie as a model ecosystem. How and when did grasslands evolve And where and when did they become established How many species and biotrophic levels are interconnected in a regularly disturbed environment Are there keystone species What are the ecological forces that maintain, destroy, and restore balance Glacial retreat, fire, deep-rooted perennial grasses, large herbivores, deforestation, industrial agriculture, and biofuels are covered. We then apply what we have we learned from the grasslands to live sustainably. J. Borevitz. Spring.

3.00 Credits
PQ: PQ: BIOS 10110 or 10130. This course discusses a wide range of biological and geological phenomena in the light of evolutionary theory. The material is presented in the form of scientific inquiry to provide insight into how we know what we know. Concepts are presented using examples relevant to the human condition and human evolution. The diversity of organisms is demonstrated throughout the course in the lectures, using living and preserved specimens. Practical sessions in the Evolving Planet exhibit of the Field Museum required. P. Sierwald, R. Bieler. Winter.

3.00 Credits
PQ: BIOS 10110 or 10130. Converting light energy of the sun into food, plants feed, directly and indirectly, all organisms. This course discusses the process and the evolution of the energy conversion mechanisms. Nitrogen fixation and its ecological significance are included. The control mechanisms of flowering through photoperiodism and the biological clock, which ultimately lead to fruit and seed production, are considered. This is followed by a discussion of the origin of crop plants, agriculture, and the ecology and breeding of crops including their genetic modification. The demand on the natural resources brought on by an ever-increasing human population is the underlying theme of this course. M. Ruddat. Spring.

3.00 Credits
PQ: BIOS 10110 or 10130. In recent years, there has been an explosion of genetic and other biological discoveries expanding our notions of evolution of life on Earth. At the same time, there has been a rise in the rejection of evolution, in particular of a movement supporting a group of ideas called intelligent design. We explore questions such as: Who is right How do biological discoveries inform us What is the role of science in helping us understand the world Should intelligent design be taught along with evolution in public schools I. Pavlova. Autumn.

3.00 Credits
PQ: BIOS 10110 or 10130. This course examines the ecology and evolution of insects, from their early evolution over 350 million years ago to their adaptations that allow them to exploit nearly every habitat on earth and become the most diverse animal group on the planet. We explore the basic biology of insects that have allowed them to become the largest group of animals on the planet, making up approximately 1.5 million of the 2 million described species. E. Larsen. Autumn.
