Energy flow is a unifying principle across a range of living systems, from cells to ecosystems. With energy flow as a major theme, this course covers macromolecules, cells, respiration and photosynthesis, physiology and homeostasis, population and community interactions, and ecosystems. Throughout the course, the diversity of life is explored. The course also introduces students to the process of scientific thinking through discussion of research methodology and approaches. Majors and nonmajors may enroll. Biology majors should take this class prior to the junior year. No prerequisite. This course will be offered every year.
This course will examine the ecological theory and practice of restoration ecology through lectures, class discussion, field trips and a class project on restoration design. The science of ecosystem restoration has grown dramatically over the past decades, emerging as an active subdiscipline of biology. The challenges of restoration are many, and include our incomplete understanding of the complexity of ecosystems and the limits this places on our ability to predict ecosystem response to restoration efforts. Restoration ecology spans a range of activities and scales, ranging from the systematic, long-term restoration of major ecosystems such as the Everglades or the Colorado River watershed, to small-scale restoration projects such as the prairie and wetland restoration projects at Kenyon's Brown Family Environmental Center. This class we will focus on the causes of ecosystem degradation, methods to quantify ecosystem response, the application of concepts such as ecological integrity, ecosystem resilience and alternative stable states. Prerequisite: BIOL 115 and a 200-level Biology course or permission of instructor.
This course is designed to introduce students to the study of freshwater ecosystems, including lakes, streams and wetlands. Human activities have had profound impacts on freshwater life and an understanding of the dynamics of freshwater systems is instrumental in determining how to protect and restore these habitats. We will examine the physical, chemical and biological factors influencing biological diversity and productivity and will emphasize the application of ecological principles to study these systems. Possible topics include the effects of agricultural run-off and eutrophication; erosion resulting from human development; the introduction of non-native species; toxic contaminants; and restoration techniques. Standard texts as well as primary literature will be used. Prerequisite: BIOL 115 or equivalent and at least one 200- or 300-level biology lecture course. May be offered in alternating years.
In this laboratory course, students will employ methods used in the study of freshwater ecosystems. It is designed to complement either BIOL 251 or BIOL 352. Students will learn to identify freshwater organisms, quantify biological, chemical and physical parameters that affect these organisms, and design ecological experiments. Throughout the course, laboratories will emphasize hypothesis testing, quantitative methods and experimental design. Field trips will be taken to local natural habitats and many lab periods will be spent doing fieldwork. Prerequisite: BIOL 109Y-110Y. Prerequisite or corequisite: BIOL 251 or 352 or permission of instructor. May be offered in alternating years.
See course description for BIOL 385.
This course provides the student with the opportunity to pursue an independent investigation of a topic of special interest not covered, or not covered in depth, in the current curriculum. The investigation, designed in consultation with the chosen faculty mentor, may be designed to earn .25 or .5 unit of credit in a semester. BIOL 393 is ordinarily is a library-oriented investigation. (For laboratory-oriented independent research, see BIOL 385 and 386.) Normally, students receive credit for no more than two semesters of independent study. Independent study does not count toward diversification requirements for the biology major. Prerequisite: permission of instructor and department chair.
Individual study in biology, typically pursued by juniors or seniors, provides an opportunity to pursue an independent investigation of a topic of special interest not covered, or not covered in depth, in the curriculum. The investigation, designed in consultation with the chosen faculty mentor, may be designed to earn .25 or .5 unit of credit in a semester and may be continued in the second semester. BIOL 393 ordinarily involves literature-oriented investigations. (For laboratory-oriented independent research, see BIOL 385 and 386.) Normally, students receive credit for no more than two semesters of individual study. Such study cannot be used to fulfill either the natural science diversification requirement or the requirements for the major. To enroll in individual study, a student must identify a member of the Biology Department willing to mentor the project and in consultation with him or her, draft a syllabus, including readings, a schedule and assignments, which must be approved by the department chair. The student should meet regularly with the instructor for at least one hour per week or the equivalent. The amount of graded work should approximate that required, on average, in 300-level biology courses, at a minimum. In the case of group individual studies, a single course syllabus may be submitted, assuming that all group members will follow the same syllabus. Students are urged to begin discussion of their proposed work well in advance, preferably the semester before, so that they can devise a syllabus and seek departmental approval before the registrar's deadline.
This course continues the honors research project and gives attention to scientific writing and the mechanics of producing a thesis. A thesis is required and is defended orally to an outside examiner. The letter grade is determined by the instructor and project advisor in consultation with the department. Prerequisite: BIOL 385 or 386, and 497.
This course examines contemporary environmental problems, introducing the major concepts pertaining to human interactions with the biosphere. We will explore this interaction at both local and global scales. Course topics include basic principles of ecology (flows of energy, cycling of matter and the role of feedback), the impacts of human technology, the roots of our perceptions about and reactions to nature, the social and legal framework for responding to problems, and economic issues surrounding environmental issues. We will discuss methods for answering questions regarding the consequences of our actions and, using a systems approach, focus on methods for organizing information to evaluate complex issues. The format of the course will be three-quarters discussion and lecture and one-quarter workshop. The workshops will include field trips, experience with collecting data, and application of systems thinking. This course counts as a biology course for diversification. No prerequisite. Offered every spring.
In this course, students will examine special topics in environmental science, gaining subject knowledge so that they can lead educational experiences for elementary school classes visiting the Brown Family Environmental Center. Students will participate in two workshops at the beginning of the semester and then participate in at least four programs for visitors. Participants will keep a journal and submit a final report on their experiences along with evaluations of the effectiveness of the programs. Prerequisite: ENVS 112 or BIOL 112 or equivalent or permission of instructor. Offered each semester.
The purpose of the course is to introduce students to the principles of sustainable agriculture through hands-on experience on local farms and through readings of current literature. The course thus combines fieldwork and seminar-style discussion. Work on the farm will be varied, determined by the seasons and farm projects under way. In addition, students may be taken to the local Producers Livestock Auction and other off-farm sites as the time and season allow. Students can expect to handle and feed animals, clean barns, harvest and plant crops, prepare farm products for market, build and repair fences, bale hay, and work with, repair or clean equipment and buildings. Readings will be drawn from relevant books, current environmental literature and the news media. Discussions will be student-led and combine readings and their experiences in the field. Completion of ENVS 112 is strongly encouraged. Also, students must have available in their academic schedule four continuous hours one day per week to spend working at a local organic farm (travel time will be in addition to these four hours). In addition, students will participate in a weekly seminar discussion of assigned readings, lasting from an hour and a half to two hours. Participation is limited to eight to 10 students and permission of instructor is required. Preference will be given to juniors and seniors. No prerequisite. Offered every fall.
The intention of this capstone seminar is to draw together and apply the concepts learned in earlier courses in the Environmental Studies Concentration. The focus of the course will be on case studies of natural-resource management, with specific topic areas to be determined. In this strongly interdisciplinary effort, we will explore ecological, economic, social and legal issues that influence how people exploit natural resources, and whether that exploitation is sustainable. Students will be expected to develop and communicate their understanding of the complex and inseparable relationships of human well-being, ecosystem services and environmental management. Prerequisite: junior standing and must be pursuing the Environmental Studies Concentration. Offered every year.
Because the Environmental Studies Concentration has no faculty of its own, the nature of an individual study will necessarily vary dramatically depending on the home discipline of the faculty member guiding the course. Details regarding the expected number of contact hours per week, workload, and assessment will be left to the discretion of the faculty member guiding the individual study. There are no formal restrictions on who can pursue an individual study in environmental studies. Individual studies are not intended to replace an elective course in fulfilling the requirements of the Environmental Studies Concentration.
