Introduction to Ecology, BI271, Lecture B

Homepage and syllabus for Introduction to Ecology, BI271, Lecture B

BI271 Lecutre B, 4 credit hours, fall semester 2017

Ecology is the study of the spatial and temporal patterns of the distribution and abundance of organisms, including causes and consequences. Studying these patterns provides us with the scientific foundation for understanding natural processes and environmental problems. This course will examine ecological interactions at a wide range of scales from the molecular level, through individuals, populations, communities, ecosystems, and ultimately to the biosphere. We will study how these interactions produce the patterns and processes we observe around the world. In the field-based laboratory we will learn to generate testable ecological hypotheses, develop experimental designs to test our hypotheses, and use statistical inference to quantiatively assess the outcome of our experiments, while gaining first-hand familiarity with local ecological communities.

Titles and names

Students are often curious about how to address their professors. I am comfortable with Dr. Moore, Professor Moore, or Chris. What’s most important to me is that we create a culture of mutual respect in the classroom. As a sign of respect to you I will, by default, address you as Ms. and Mr. followed by your last name. Should you have preferred way of being addressed (first name, nickname, etc.), please communicate that to me.

  • Problem sets will include several quantitative and conceptual problems that are designed to help you apply and more deeply understand some of the concepts covered in the lecture material. There will be one probem set per Unit, and they will be disributed in lecture and due at the beginning of lecture, two meetings later.
  • Paper critiques are designed to help you more thoroughly understand the primary mode of scientific vetting and communication: peer-reviewed journal articles. There will be three paper critiques of three different papers throughout the semester, with each subsequent critique designed to be more challenging by asking you to more thoroughly understand and substantively criticize the article.
  • Examinations are a method used to gauge your understanding of the lecture material while simultaneously rewarding those who have mastered it.

Lecture schedule (1 introduction, 32 lectures, 3 reviews, 3 examinations)

Colby College is supportive of the religious practices of its students, faculty, and staff and is committed to ensuring that all students are able to observe their religious beliefs without academic penalty. If you observe a religious holiday that will impact your work in this course, please see me at the beginning of the term. We will then work to find a reasonable accommodation that will allow you to complete the academic work.

*(1) CBH means we are reading from the textbook, Cain, Bowman, and Hacker (2) “Weekly reading” should be read before the Monday where it’s listed. I will have the readings posted one week before we begin covering the material, at the latest.

Academic integrity

Honesty, integrity, and personal responsibility are cornerstones of a Colby education and provide the foundation for scholarly inquiry, intellectual discourse, and an open and welcoming campus community. These values are articulated in the Colby Affirmation and are central to this course. You are expected to demonstrate academic honesty in all aspects of this course. If you are clear about course expectations, give credit to those whose work you rely on, and submit your best work, you are highly unlikely to commit an act of academic dishonesty.

Academic dishonesty includes, but is not limited to: violating clearly stated rules for taking an exam or completing homework; plagiarism (including material from sources without a citation and quotation marks around any borrowed words); claiming another’s work or a modification of another’s work as one’s own; buying or attempting to buy papers or projects for a course; fabricating information or citations; knowingly assisting others in acts of academic dishonesty; misrepresentations to faculty within the context of a course; and submitting the same work, including an essay that you wrote, in more than one course without the permission of the instructors.

Academic dishonesty is a serious offense against the college. Sanctions for academic dishonesty are assigned by an academic review board and may include failure on the assignment, failure in the course, or suspension or expulsion from the College.

Athletic participation

While Colby College is supportive of athletic participation by its students, academics takes priority over athletics. Both NCAA and Colby rules prohibit missing class for practices. In the case of overlapping commitments between class and athletic competitions, the student must meet with the professor as soon as possible to discuss these overlaps. The student may request permission to miss class and make up the missed work; the instructor has final authority either to grant or to withhold permission

Sexual misconduct/Title IX statement

Colby College prohibits and will not tolerate sexual misconduct or gender-based discrimination of any kind. Colby is legally obligated to investigate sexual misconduct (including, but not limited to sexual assault and sexual harassment).

If you wish to speak confidentially about an incident of sexual misconduct, please contact Colby Counseling Services (207-859-4490) or the Director of the Gender and Sexual Diversity Program, Emily Schusterbauer (207-859-4093).

Students should be aware that faculty members are considered responsible employees; as such, if you disclose an incident of sexual misconduct to a faculty member, they have an obligation to report it to Colby’s Title IX Coordinator. “Disclosure” may include communication in-person, via email/phone/text, or through class assignments.
