"A lake is a landscape's most beautiful expressive feature: it is earth's eye, onlooking into which the beholder measures the depth of his own nature." - Henry David Thoreau-
OBJECTIVES/ COURSE DESCRIPTION Limnology is aquatic ecology, the study of inland waters. This course focuses on why aquatic systems function as they do. The course develops a comprehensive and integrated understanding of physical, chemical and biological processes occurring in lakes, streams and wetlands using the scientific method to investigate and contrast basic ecological processes operating in various systems. Limnology is one of three freshwater biology courses offered at Kennesaw State University. To learn more about these courses and how these courses fit together see http://science.kennesaw.edu/~jdirnber/AquaticKSU/AQKSU.html.

Thursdays will generally be fieldtrips or labs though the schedule may change due to weather. On some fieldtrip days, we may divide the class into “shifts” where different shifts will be asked to arrive at (and leave from) the field site at different times. On these dates, the first shift begins during lecture time at 8 am (obviously there will be no formal lecture at this time). Be prepared and dress appropriately for fieldwork. Don’t be late or your will figuratively and literally “miss the boat”! Tuesdays will usually be lecture days, though some dates may include short labs. In lecture, we will discuss selected topics and previously collected data, as well as generate hypotheses that will be tested during fieldtrips. You should feel free to contribute to lectures and discussions.

FIELD NOTEBOOKS You will be required to maintain a notebook of your field experiences in this course. Bring this notebook to all fieldtrips and labs. The notebook should be bound (i.e. not loose leaf, not spiral) such as the lab notebooks required in chemistry or bound blank journals sold at art supply stores and bookstores. For those in Dr. D.’s Invertebrate Zoology, Oceanography or Aquatic Biodiversity class, or Dr. E’s Vert Zoo class, the notebook required in Limnology is not as extensive or involved (though you may use these old notebooks if there is sufficient space left),
Required items in your notebooks: date, name of study system, location (relative to nearest town or other marker, and county/state), type of habitat, weather conditions. a rough map of the study site all of the raw data if you have been designated as the ‘data collector’ for your group. Even if you are not the data collector, you should include some data that is representative of the study system as well as any data that strikes you as unusual or potentially important. description of sampling techniques a brief, overall reflection on the study system (e.g. what surprised you, how did this system compare to others you have experienced…) Suggested items (do not feel that you have to record everything you see, hear or measure in the field): list of organisms collected and observed (do as best as you can but it is likely that you will not be able to document all species we encounter). Underline genus and species names with straight lines (capitalizing the former) and put squiggly lines under common names. observations of microhabitats (descriptions and inhabitants) quick sketches concentrating on topography, habitats, behaviors, sampling equipment, etc. anything else that might be of interest to you or others (be creative/observant). This might also include observations on local culture, land practices, etc. Great insights and understanding in science have arisen by bringing together disparate observations. Details can enhance retention and are often important when interpreting the data for your lab reports.
You can use both written descriptions and drawings in your notebooks. Notebooks will be graded for completeness at the end of the semester (20 pts). There will also be one ‘pop’ checks of notebook at the end of fieldtrips (5 pts), so be sure to bring your notebook on all fieldtrips.
PREREQUSITES Two lab science courses and junior or senior level standing.
REQUIRED BOOKS: None. There will be web-based readings and assigned papers instead. GRADES: Exam #1 100 pts each = 100 pts Exam #2 100 pts each = 100 pts Final Exam 100 pts each = 100 pts Lab reports 50 pts = 200 pts Paper summaries on trophic cascade 25 pts = 25 pts Group work / Participation 25 pts = 25 pts Field Notebooks (including in-field checks) 25 pts = 25 pts 575 pts A= 90%; B= 80%; C= 70%; D= 60%
OFFICE HOURS DR. D.: MW 2-3:30 PM; TH 2-3:30 PM FRIDAY 1-3 PM If you cannot make it during these times, I will be glad to make an appointment with you. If you are having any problems with the material, please come by and see me. Don't put it off until it is too late.
POLICIES Safety must be a primary concern when in lab and in the field. You must review the Laboratory Safety Guidelines at: http://science.kennesaw.edu/biophys/LabSafetyGuideNoPic.doc Attendance: You must show up for field trips on time or you may get left behind! Attendance on trips is important because some exam questions will be based on observed systems. An understanding of processes within a study system is certainly enhanced by first-hand observation of that system. o Unexcused absences on field trips and labs will result in a 10% reduction per absence on that lab report. o To make-up excused absences for field and lab days, you must cite 3 additional references in your lab report. These references must be relevant to our study and must be from referred journals. Late lab reports will result in a 5% reduction per class period on that lab report. The penalty is initiated at the beginning of each class/lab period (i.e. if the lab is not turned in at the start of class on the day it is due, 5% is taken off). Keep all of your returned, graded work (exams and lab reports). You must have these materials if you decide to contest your final course grade. Do not turn assignments in by e-mail or other electronic formats. Hard copies only. ACCOMMODATIONS Any student with a documented disability or medical condition needing academic accommodations of class-related activities or schedules must contact the instructor immediately. Written verification from the KSU disAbled Student Support Services is required. No requirements exist that accommodations be made prior to completion of this approved University documentation. All discussions will remain confidential.
ACADEMIC WITHDRAWL POLICY To withdraw, the student should complete an official withdrawal form in the Office of the Registrar. Students who officially withdraw from courses on or before the last day to withdraw without academic penalty will receive a “W”. Students who officially withdraw after the last day to withdraw without academic penalty (and before the last three weeks of the semester) will receive a “WF”, which will be counted as an “F” in calculation of their grade point average. The only exceptions to these withdrawal regulations will be for instances involving unusual circumstances, which are fully documented. Students may appeal to the academic standing committee for consideration of unusual circumstances. LAST DATE TO WITHDRAW WITHOUT ACADEMIC PENALTY OCTOBER 12th 2009
ACADEMIC INTEGRITY Every KSU student is responsible for upholding the provisions of the Student code of Conduct, as published in the Undergraduate and Graduate catalogs. Section II of the Student Code of Conduct addresses the University’s policy on academic honesty, including provisions regarding plagiarism and cheating, unauthorized access to University materials, misrepresentation/falsification of University records or academic malicious/intentional misuses of computer facilities and/or services, and misuse of student identification cards. Incidents of alleged academic misconduct will be handled through the established procedures of the University Judiciary Program, which includes either an “Informal” resolution by a faculty member, resulting in a grade adjustment, or a formal hearing procedure, which may subject a student to the Code of Conduct’s minimum one semester suspension requirement.
