F-462 RANGELAND ECOLOGY SPRING SEMESTER 2009 Instructor: Don Bedunah; Office: CHCB 438; Phone 2573 (don.bedunah@cfc.umt.edu) Office Hours: To be arranged (contact by email or phone- or if door is open, please feel free to talk with me). Rangeland Ecology is the scientific discipline that is concerned with the relationships between organisms and their past, present, and future environments. These relationships include physiological responses of individuals, structure and dynamics of populations, interactions among species, organization of biological communities, and processing of energy and matter in rangeland ecosystems. Objective: To review and discuss the major ecological principles and processes which influence the function of rangeland ecosystems. Ecological processes are similar across all types of ecosystems; however, some processes are more important determinants in some ecosystems than in others. We will focus on those processes that greatly influence rangeland ecosystems such as succession, disturbance (e.g. herbivory, fire, and climatic variation), and nutrient cycling. Diversity and sustainability of ecosystems are everincreasing important considerations. Text: No text. Lecture notes and assigned readings will be on ERES. Password: F462. Grading: There will be two mid-term exams, a final exam and a paper. The final exam is comprehensive and may be optional. The final grade is 25% final and 50% the first two tests (75% if final is optioned out of) and remainder is the paper score. Graduate students will present their papers to the class during the last week of class. Upper Division Writing This course is one of three courses needed to satisfy the upper division writing requirement for CFC majors. Each student is required to achieve satisfactory scores on a sophomorelevel writing course (FOR 220/WBIO 245 or equivalent). The successful completion of one of these courses plus the writing proficiency exam will be prerequisites for completion of the upper division distributed writing requirement. Assessment of student writing will be on the basis of the following criteria: 1. A clear statement of purpose (hypothesis or question or goal) within the scientific context of the specific discipline. 2. The development of effective logical arguments using evidence and/or theory from the discipline or supporting disciplines. 3. Writing meets discipline-specific writing conventions including the proper citation of sources of information. 4. Demonstrate appropriate English language usage. All students must practice academic honesty. Academic misconduct is subject to an academic penalty by the course instructor and/or a disciplinary sanction by the University. All students must be familiar with the Student Conduct Code. The Code is available for review online at http://www.umt.edu/SA/VPSA/index.cfm/page/1321.
