Biology 406 - Ecology

 

Lecturer:

Danny J. Gustafson, Ph.D. (Office phone: 953-7876, email: danny.gustafson@citadel.edu)
Office: Duckett 301
Office Hours: M,W 9-10, M 12-1 and by appointment.
 
Lecture:

MWF 10:00-11:00 in Duckett 114

Lab: W 1 - 4:50 in Duckett 201
   
Textbook:

The Economy of Nature (5th edition) by Ricklefs. Freeman / Worth Publishers,

New York, NY. ISBN: 0-7167-3883-X. Laboratory material will be provided by DJG.

 
Course Goals:

Ecology is the study of the natural environment and of the relations of organisms to each other and to their environment. Students will be exposed to ecological theories and case studies of ecological interactions at multiple levels of organization.

The course is divided up into four sections that roughly correspond to organismal, population, community ecology, and species interactions.

 
Exams:

Each exam will cover the material presented in lecture and the assigned book chapters.*

There will be four hourly exams, each following approximately 8 lectures. Each of these

exams and the comprehensive final exam will be worth 100 points each. The lowest exam

score will be dropped, hence there WILL BE NO MAKE-UP EXAMS OFFERED.

Total points from the exams = 400.

 
Grading

The course grade will consist of the total of your four exams (400 pts) plus laboratory

(150 pts) for a total of 550 pts possible.

A = 90-100%

B = 80-89%

C = 70-79%

D = 60-69%

F = <60%

 
Attendance:

According to Citadel policy, class attendance takes priority over all other normal activities.

If absences exceed 20% of the total meetings, the student can receive a grade of F.

Excused absences may be permitted if and only if I have been give prior notice.

The Citadel's honor system applies to all functions related this course.

 

Dates  Topic
Jan 14 Pre-Exam (not for a grade) and introduction to the course.
Jan 16 – Feb 4

Organismal Ecology (Chapters 9 – 12) 
We will look at adaptations to environmental heterogeneity, life history traits, sexual advantages (evolutionarily speaking), and social structure advantages.

Feb 6 Exam 1 (100 pts)
Feb 9 – Feb 25

Population Ecology (Chapters 13-16)

In the population ecology section we will discuss population structure, how it may affect population growth, and how / why temporal and spatial dynamics are important.

Feb 27 Exam 2 (100 pts)
Mar 1 – Mar 17

Species Interactions (Chapters 17-20)

Predatory / prey dynamics, competition theory, co-evolution and mutualism will be discussed within the context of natural systems

Mar 19 Exam 3 (100 pts)
Mar 22 – Mar 26 Spring Break
Mar 29 – Apr 21

Community Ecology (Chapters 21-23 & 25)

We will investigate communities structuring (relative to population dynamics), community development (succession), biodiversity and conservation biology.

Apr 23 Exam 4 (100 pts)
Apr 26 Post-exam and review for final
Final April 30 at 1 pm in Duckett 114

 

I would suggest focusing on the ideas and concepts discussed in lecture, using the book to supplement or clarify. All of the information in the textbook is valuable and potential exam material, but I tend to test on ideas that I thought were important enough to lecture about or discuss in class / lab.

 

Laboratories will meet in Duckett 201 unless otherwise instructed. Laboratory attendance and participation are mandatory and any person missing 2 lab meeting will be removed from the class and receive a grade of F. Your laboratory grade will consist of three 40 point scientific papers (total 120 pts) and lab participation (30 pts) for a total of 150 points.

 

There are four possible laboratories which can be written up as your three scientific papers and the choice is the students. Students will select from the Mimicry, Paramecium population regulation, Cohort Life Tables, and Forest Composition labs and have your paper due 2 weeks (14 days by 5 pm) following the analysis and discussion lab period. Your scientific papers must be typed, follow the format of the journal Ecology, and have a maximum of 10 pages text including abstract, literature cited, plus tables and figures. The tables and figures should not simply represent your raw data, instead they should contain summaries of your data and convey information not presented in the text of the results. Failure to follow these instructions will result in a lower grade or the return of your paper not graded. Late papers will receive a score of zero (0). Field laboratories may require the class to travel some distance to conduct the experiment, so it is imperative that you are on time. We can not wait for you if your late and two missed laboratory periods will result in an F for the course. FYI: Bad weather seldom leads to cancellation of laboratories.
