OC 542 / 442 – Estuarine Ecology– Syllabus – Spring 2007 OC 542/ 442 Estuarine Ecology Dr. Anthony D'Andrea Burt 204 College of Oceanic and Atmospheric Sciences 541-737-8079 dandrea@coas.oregonstate.edu http://oregonstate.edu/~dandreaa/Index.html Overview This course is designed to provide students with an integrated view of the ecologic processes in estuarine environments, with a special emphasis on how these processes impact the biogeochemical cycling of carbon and nitrogen. The major topics of the course include: introduction to estuarine systems including the geomorphology, physical oceanography and chemistry of estuaries; abiotic and biotic controls on estuarine nutrient cycling; primary production by phytoplankton, benthic micro- and macroalgae, and macrophytes; detrital food webs and carbon cycling; secondary production by benthos, plankton, and nekton; and carbon and nitrogen cycling in salt marsh, seagrass, open tideflat, and oyster reefs. Particular emphasis will be placed throughout the course in identifying key differences in ecological processes between Pacific west coast estuaries and East and Gulf coast estuaries. Class discussions and current literature will also be used to encourage students to integrate lecture topics and achieve a comprehensive understanding of how the physical, chemical, and biological properties of estuaries regulate ecological processes. Class meetings: There will be 20, each lasting 80-120 minutes. They will generally follow a lecture format, but I welcome questions and discussion points raised by students. Each of you has your own knowledge, your own scientific perspective and your own interests. The group is a small one. We encourage each of you to ask questions, to add things you know from other work you’ve done and to try to answer questions raised by others. Learning Outcomes: • • • All students (graduate and undergraduate) are expected to develop an understanding of the ecological processes in estuarine systems, demonstrate how these processes affect the cycling of carbon and nitrogen, and apply these concepts to questions and problems (e.g. nutrient loading, eutrophication, restoration) in different estuarine systems. Graduate students taking this course are expected to develop the ability to critically read and understand papers from the literature, evaluate potential flaws in past or current estuarine paradigms, articulate ideas, and distinguish prospective future research directions in estuarine ecology. They also will lead all of the discussion sessions. In addition, they are expected to integrate information from the course and formulate linkages between estuarine ecosystem processes and the student’s research (or management) project and/or interests. Undergraduate students in the course will also develop the ability to critically read and understand papers from the literature, and actively participate in the discussion sessions. However, undergraduates will be paired with graduate students during discussion sessions rather than leading them directly. 1 OC 542 / 442 – Estuarine Ecology– Syllabus – Spring 2007 Textbook and other resources Primary Textbook: Mann K.

(2006) Biogeochemistry of Estuaries, Oxford University Press [I have a spare copy] The class will be supplemented by both classic papers covering topics in the course as well as selected papers dealing with contemporary issues in estuarine ecology. Readings Assigned readings will consist of selected chapters from the Mann (2001) textbook, selected chapters from the Day et al. (1989) textbook on reserve in Patullo, selected chapters from other books, and journal articles. These assigned readings will be very important. Much of the factual content of the course is in the readings, so it is imperative that you do them, and that you do not get behind. Pre-class readings. Each of these will be associated with a particular class meeting date. The pre-class readings for the course are listed in the syllabus along with the topics. You should read these book chapters and journal articles before you come to the corresponding class meeting, and preferably only a short time beforehand so that the material is fresh in your mind when you come in. In addition to the assigned readings, I plan to hand out supplemental reading lists from time to time during the course (approximately weekly). These are not assignments. You can learn a lot about the subject of estuarine ecology, and do very well in this course, without reading any of them. These supplemental papers are not required readings. They are intended to flesh out information from the lectures, and give you an avenue into the literature on things that may be of particular interest to you, either during the term or later on. Access to assigned readings. Assigned reading is available in three different ways: 1. As PDF files on the College of Oceanic and Atmospheric Sciences (COAS) ‘Terra Firma’ system and the OSU ‘Blackboard’ system. You can save the files or print copies of the 2 OC 542 / 442 – Estuarine Ecology– Syllabus – Spring 2007 readings so that you have your own copies. I plan to have readings for a given week posted by the Friday preceding that week’s lectures. Obviously this will not be possible for week one. 2. The old-fashioned way, by looking them up. For example, the Day et al. (1998) readings are accessible from the copies in the reserve section of the Patullo Library (in the Ocean Admin building). For journal articles, I will give you the full citation for each reading assignment. All are in textbooks or journals that are readily available, and many are in journals that are available electronically through the Valley Library. So if you prefer to go to the library and look them up (either in person or using a computer) it should be easy to do so. 3. By way of the Instructor. If you have any difficulty at all getting hold of these readings by the methods described above please call, e-mail or see me. This may be particularly useful to those of you who are not students in COAS. I can show you how to navigate Terra Firma or Blackboard or, if all else fails, e-mail you a PDF file of any assigned reading. I will also have hard copies of the readings in a folder in the Reserve section of the Patullo Library in the COAS Admin building. Handouts during class meetings. Before or within a day of each class I will make all the visual materials we used available as PDF files in the ‘Lecture materials’ folder for that class date on both Terra Firma and Blackboard. This is so that you can have clean copies of these materials even if you mark up your hard copies extensively during class (which is encouraged). It will also give you color copies of the slides presented in color (photographs, maps, conceptual diagrams, etc.) which sometimes lose considerable information when copied in black and white. As was the case for the reading assignments, please get hold of me if you would like PDF files of the visual materials shown in class but have any trouble accessing them off the COAS Terra Firma or OSU Blackboard systems. Grading Grades will be based on a take-home midterm exam, active participation in discussion sessions, a written research topic paper, a special topics presentation, and overall participation in class activities. Take-Home Midterm 30% Discussion Sessions 20% Research Topic Paper 25% Presentation 20% Participation 5% Caveats and Small Print All materials generated for this class, which include but are not limited to syllabi, in-class materials, and exams, are copyrighted. You do not have the right to distribute these without written consent of the instructor. 3 OC 542 / 442 – Estuarine Ecology– Syllabus – Spring 2007 Plagiarism: As commonly defined, plagiarism consists of passing off as one's own the ideas, words, writings, etc., which belong to another. In accordance with this definition, you are committing plagiarism if you copy the work of another person and turn it in as your own, even if you should have the permission of that person. Plagiarism is one of the worst academic sins, for the plagiarist destroys the trust among colleagues without which research cannot be safely communicated. This is a grievous offense and will not be tolerated. Individuals guilty of plagiarism will be severely penalized. The American with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring accommodation, please contact the instructor. Discussion Sessions There will be three, two-hour discussion sessions during the course. These sessions will involve themes, current questions, and management issues in estuarine ecology. For each discussion session, students will read papers from the current literature and be given a list of thought questions to help guide the discussion. Each discussion session will be led by a group of students in the class. The purpose is to encourage and train students to critically read the literature, introduce them to the state of current research, articulate ideas, and recognize potential future directions in estuarine ecology. Keep in mind that a large part of your grade for these sessions will be based on active participation in the discussion. Example: Discussion 1: Atlantic vs. Pacific: can east coast studies be readily applied to Pacific small river estuaries? Discussion 2: Salt marsh: the pulsing and source-sink paradigms Discussion 3: Eutrophication in estuaries: A case study of Chesapeake Bay Research Topic Paper The purpose of this assignment will be to place your research interests or topic within the context of estuarine ecosystem processes and evaluate your ability to critically read the literature. The narrative should emphasize an ecosystem perspective and be composed in the following general format: Introduction: Briefly explain your research topic. This should be written so a general reader will know what you are working on and why. Thesis statement: A formal statement of the primary hypothesis or hypotheses you will be testing. Narrative: Three to five pages of text, single-spaced (excluding figures and references), that explain the linkages between your topic and estuarine processes. I will be looking for how well you can: (1) synthesize information from the course as it applies to your research (or management) interests and (2) put your research in an ecosystem perspective. I encourage the use of figures and illustrations but do NOT include figures handed out during the class. 4 OC 542 / 442 – Estuarine Ecology– Syllabus – Spring 2007 The end product of this paper will help you integrate information from the course and hopefully be useful when you write your research proposal, project report, or thesis. Group Presentation The last 2-4 class sessions will be set aside for student lectures on estuarine topics of interest which were not explicitly covered in the class. The purpose of this is two-fold: (1) have students integrate information from the course into topics relevant to their interests, and (2) improve the public speaking and presentation skills of the students. Each student or group will meet with the instructor to discuss the topics of their presentation, develop a reading list and assign readings, concisely present the topic in 20-30 minutes, and field questions on the topic and presentation. example topics can include (but are not limited to): Eutrophication Pollution Salt marsh restoration Hypoxia Harmful algal blooms Estuarine habitat and salmonid life cycles Management/policy of estuarine systems Estuarine Fisheries Non-native species in estuaries Shellfisheries of estuarine systems Role of birds in estuarine food webs Mangrove ecosystems 5 OC 542 / 442 – Estuarine Ecology– Syllabus – Spring 2007 OC542 / 442 – Estuarine Ecology– Spring 2007 - Schedule Date Lecture Topic April 3 April 5 April 10 1 2 3 Overview of course; Intro to estuaries Estuarine classification Estuarine physics April 12 4 Estuarine sediments and sediment properties April 17 5 Estuarine chemistry and nitrogen cycling April 19 6 Denitrification in estuarine systems April 19?
