BIOL

68 courses with the subject BIOL, each shown exactly as we captured it from the college's catalog, with every element we hold. Where the wording looks broken, that is our reading of the catalog, not the college's text.

BIOL 101Creatures and Curiosities4

This course deals with unfamiliar, mysterious, beautiful, grotesque, and overlooked animals all around us: the invertebrates. We will explore animal evolution and focus on the biology of creatures such as sponges, jellyfish, insects, and corals. In addition, we will discuss the cultural role of animals as curiosities - as specimens in cabinets and museums, or the subjects of phobias and urban legends. Drawing on topics in marine biology and entomology, students will learn about the ecology, life cycles, and anatomy of major groups of animals through lectures, observation of live animals, and dissections. Students must complete two field trips outside of class time. Two 1-hour lectures and one 1-hour lab per week. Offered most years, fall semester.

BIOL 110Plants, Environment, and Society4

The food we eat, the air we breathe, and the landscapes we inhabit are shaped by plants. Plants are also at the heart of many global issues impacting society: food security, climate change, development and land degradation, and environmental inequity. In this course, we focus on the physiology, ecology, and biodiversity of plants, as well as their role in human life and society. We will explore topics that span agriculture and biotechnology, climate change and biodiversity, historical and modern use of plants as commodities, and urban ecology. Three lecture hour each week. Offered occasionally.

BIOL 170Ecology and the Environment4

Cross-Listed as ENVI 170 This course dives into a range of topics to study how species, populations, communities, ecosystems, and biomes function in our changing climate. We will emphasize biological nutrient and energy cycling, population dynamics, animal and plant species interactions, disturbances and response to disturbances, and ecology in urban and agricultural landscapes. We will examine Ecology under four conceptual ‘lenses’: Climate Change, Environmental Justice, Land Use, and Ecosystem Services. These lenses provide critical insight into how scientists, policy makers, land managers, and other stakeholders evaluate complex ecological and environmental systems. Labs will be field and data-based, and emphasize the development of hypotheses, novel data collection at Ordway Field Station, and statistical analysis. Three hours lecture and one three-hour laboratory each week. Offered every semester.

BIOL 180Biodiversity and Evolution4

An introduction to the diversity and history of life. We begin with basic evolutionary patterns and processes that have shaped living things, and then move on to the major groups of organisms (their morphology, physiology, reproductive cycles) and their evolutionary origins and relationships. Using recent findings from such diverse fields as molecular phylogenetics, developmental biology, and paleontology, this course introduces students to the major branches on the tree of life. Three lecture hours and one three-hour lab each week. Offered every semester.

BIOL 275Outdoor Environmental Education in Theory, Policy and Practice4

Cross-Listed as EDUC 275 and ENVI 275 This course provides an introduction to outdoor education as an opportunity to promote social justice and environmental sustainability in a globalized world. Informed by relevant philosophical, psychological, cultural and political-economic frameworks, in addition to critical issues in public education policy and practice, we will explore interdisciplinary approaches to outdoor environmental education appropriate for students across the K-12 continuum. We will utilize the Katharine Ordway Natural History Study Area (Ordway Field Station) as an outdoor classroom and will adapt curriculum from the Minnesota Department of Natural Resources (DNR) and other outdoor education organizations to assist elementary school teachers and students in fulfilling Minnesota K-12 Academic Standards. Early in the semester, all students will participate in a weekend retreat at the Ordway Field Station. Weekly lab sessions will include field days during which course members design and implement educational experiences for elementary school children at Ordway, small group work days for preparing field day lesson plans, trips to local outdoor environmental education sites within the Twin Cities, and other experiential learning opportunities. Weekly seminar sessions incorporating readings, reflective writing, and individual and small group projects complement the experiential aspects of the course. As the semester progresses, each course member will develop a curricular unit aimed at teaching an important environmental issue to diverse adolescents attending urban public schools. The curricular unit is a significant undertaking that provides students with the opportunity to synthesize all aspects of the course material in a creative, pragmatic and integrative manner. Every fall.

BIOL 277Sustainable Cities: Urban Environmental Science4

Cross-Listed as ENVI 277 The world is becoming more and more urban, with over 80% of the US population and half of the world’s population living in cities. This trend (and the environmental problems it creates) will only increase throughout the 21st century, yet ecologists are just beginning to understand humans as organisms that influence their environment. Cities are hubs of activity that influence the physical structure, climate, element and energy cycling, and plant and animal communities within the urban footprint. However, these urban environments are influential well beyond their perceived borders. Urban ecologists are expanding their focus from ecology in cities, where they studied urban plants and wildlife, to the ecology of cities, where they consider human-biological interactions with increasing attention to the complex interplay among people, society, and environment. Importantly, this course acknowledges how the lived experiences of urban dwellers vary tremendously, both within and across cities. This course examines current developments in urban ecology and looks at the role it can play in planning and managing urban environments to create equitable futures for all. Offered occasionally.

BIOL 611Independent Project1

This is an opportunity for students to do independent study or research on a biological topic. This may be done in the department under the direct supervision of a faculty member; it may be done at another college or university or similar institution under direct supervision; or in certain circumstances it may be done off campus with minimal direct supervision. Given the nature of independent projects, students need to demonstrate they have the necessary academic background, including appropriate coursework, in the area they are interested in pursuing before an independent will be approved. The independent may be undertaken during a semester, during January, or during the summer.

This may be done in the department under the direct supervision of a faculty member; it may be done at another college or university or similar institution under direct supervision; or in certain circumstances it may be done off campus with minimal direct supervision. Given the nature of independent projects, students need to demonstrate they have the necessary academic background, including appropriate coursework, in the area they are interested in pursuing before an independent will be approved. The independent may be undertaken during a semester or during the summer.

This is an opportunity for students to work with professionals in the biological field outside of academia. Students will work with a faculty sponsor and their site supervisor to develop a set of learning goals, strategies to meet these goals, and methods of evaluation for the internship, including the nature of the final product. An internship is an excellent way for students to apply knowledge learned in the classroom and laboratory, to learn more biology, and to explore career options. The internship may be undertaken during a semester, during January, or during the summer and must encompass at least 35 hours of work (equal to 2.5 hours per week). S/N grading.
