ENVIRONMENTAL SCIENCES 325: FUNDAMENTALS OF ECOLOGY

FALL QUARTER, 2023

 

Instructor: Dr. David Wallin Office: ES342 Phone: 650-7526 e-mail: david.wallin@wwu.edu
Text: Ecology (6th Edition) or on Amazon (here), by, W.D. Bowman and S.D. Hacker
Note: The 6th edition of this text recently came out. Weíve been using this text for several years now and there is little difference between the editions. If youíd like to save a bit LOTS of money, feel free to buy a used older edition. Iíve seen used copies of the 4th edition for about $5. Prices for new textbooks are ridiculously high. Buy used! Note that they have added a chapter or two and renumbered things from one edition to the next. My reading assignments are based on the most recent edition. This means that, if you are using an older edition, you will need to be alert for these differences and you may need to borrow a 5th or 6th edition text from a classmate if your old edition is lacking a certain chapter.

INCLUSIVE ACCESS: Another option for getting the text is through Inclusive Access. Some of you may already be familiar with this. On the Canvas site, you will see a link for Inclusive Access. You have automatically been enrolled in this program. This provides you with online access to the text for a reduced price ($55.73 vs. ~$170 for a hard copy of the 6th edition) and you will be automatically billed for this. NOTE THAT YOU CAN OPT OUT OF THIS AND AVOID THIS BILL. IF YOU CHOOSE TO OPT OUT YOU MUST DO SO BY OCT 10. More info about inclusive access is available here.

Class Meeting: MWF 10:00-10:50, Room: ES100

Office Hours: MWF 11:00 - 12:00 ; M 2:00 (sign-up on office door) and by appointment.
Additional readings as assigned: Most, if not all of these additional readings will be available online.

Prerequisites: As noted in the WWU Bulletin and the online Classfinder, One year of biology (Biol 204, 205, 206) AND one year of general chemistry (Chem 161, 162, 163) must be completed prior to enrolling in ESCI 325.If you have not completed these courses, you SHOULD NOT enroll in ESCI 325.Just in case you are wondering if having these prerequisites really matters, click here. Note that if you are not majoring in Environmental Sciences or Biology and lack the prerequisites for ESCI 325 but you would still like to take an introductory course in Ecology, you should consider taking ESCI 225: Beginning Ecology. This course is quite similar to ESCI 325 but it is targeted at those who do not have the prerequisites for ESCI 325.

Student Learning Objectives: Upon completion of the course, students will be well versed in theoretical framework for the field of ecology as well as practical applications of this knowledge.

ATTENDANCE? Really? YupÖ..Over the past year or so, Iíve noticed that many people donít show up for class. And Iíve also noticed that this has an impact on peopleís grades. So, six times over the quarter, Iíll take attendance. You can miss ONE of these for any reason (illness, overslept, travel, etc.) with no penalty. But you will lose 1% for any additional classes that you miss beyond this. Dates that I take attendance will NOT be announced. On days when I take attendance, Iíll have a sign in sheet that you can initial. And if I catch you trying to initial for a friend who is absent, you will lose the full 5%.

Late Assignments: grades reduced by 5%/day if turned in late without a valid excuse (illness, family crisis, etc.). Assignments that are more than one week late will not be accepted without a valid excuse (illness, family crisis, etc.)

Grading: A =93; A- 90-92; B+ 88-89; B 83-87; B- 80-82; C+ 78-79; C 73-77; C- 70-72; D+ 68-69; D 63-67 D- 60-62; F 0-59

 

Academic Dishonesty: There has been a substantial increase in the number of cases of Academic Dishonesty in recent years.For this reason, all faculty members have been instructed by the Registrarís Office to provide students with explicit information about Academic Dishonesty.Briefly stated, lying, cheating and stealing will not be tolerated in any form.Actions of this type will result in severe consequences that could include a failing grade in the class and dismissal from the university.Hopefully, this does not come as a surprise to anyone.All students should review Appendix D, Academic Dishonesty Policy and Procedure Appendix D, Academic Dishonesty Policy and Procedure in the back of the University Catalog for a more detailed discussion of what constitutes academic dishonesty.For more information see:
