Behavioral Ecology, Bio359J & Zoo384K.17, Fall 2003

Prof. Ulrich Mueller

 

 

Behavioral Ecology explores the evolutionary adaptations and functions of animal behavior.  Three broad topics will be emphasized: behavioral conflict and cooperation; mating behavior and parental investment; and sexual selection.  Both theory and empirical research will be integrated to understand the evolutionary and behavioral ecology of animals.  The course also explores applications  - and limits  - of an evolutionary framework for understanding human behavioral ecology.

 

Course organization

The course is divided into two lectures per week (Tue & Thu 11:00-12:15), plus required discussion sections.  Three exams will be given during the semester (Oct 7, Oct 30, & Dec 4). Each student is expected to participate in a group project to prepare a concise, 4-minute presentation summarizing a recent research report from the primary, behavioral-ecological literature. Each student is also expected to prepare a behavioral-ecological grant application (max 400 words) following the format of a Grant-In-Aid of Research from the Sigma-Xi Scientific Research Society.

 

Discussion section

Weekly discussions in small groups will provide an opportunity to read and critique a series of seminal papers and primary research reports.  One or two short papers are generally selected for each week (see syllabus), and each student is expected to have carefully perused these readings in advance of the discussion section.  To stimulate critical thinking, each student is also expected to hand to the TA, at the beginning of the discussion section, a sheet with two questions pertaining to that week’s readings. Weekly attendance of a discussion section is mandatory.  Both attendance and participation in the discussions comprise, respectively, 5% and 10% of the course grade.

 

Discussion readings

Course packets of all discussion readings can be purchased at Longhorn Copies (2520 Guadalupe Street; north-west corner of campus at Guadalupe and Dean Keeton; open weekdays 7:30am–6:00pm, closed weekends; phone 476-4498).  See syllabus for readings assigned for each discussion.  Undergraduate discussions (BIO 359J) use a different set of readings than graduate discussions (BIO 384K.17), so make sure you purchase the right set.

 

Lecture readings

There exists no recent textbook in the area of behavioral ecology, and I have therefore compiled a set of up-to-date readings (see syllabus) that combines review articles from scientific journals, book chapters from specialized volumes, and select chapters from the textbook Behavioral Ecology by JR Krebs and NB Davis (4th edition) 1997, Blackwell Science.  Purchase of this textbook is not required, and the assigned readings from Behavioral Ecology can be purchased from Longhorn Copies (see above).  The remaining lecture readings (review articles, etc) can also be purchased as a separate set from Longhorn Copies.

 

Exams

The exams are given during lecture time on Oct 7, Oct 30, & Dec 4.  The exams are non-cumulative and cover (with few exceptions to be announced) only the material of the course segment ending with the exam.  The third exam on Dec 4th is given in place of a final exam.  Makeup exams will only be given in the case of a medical or extreme personal emergency.  It is the student’s responsibility to provide relevant documentation (e.g., a written statement from your doctor or from the CNS Dean’s office counselors in Welch Hall, 471-4536).

 

Student Presentations

Lecture material will be explored further during a series of student presentations (at the end of Thursday lecture, but sometimes Tuesday), followed by questions from the class.  Each student is expected to participate in the preparation of one 4-minute presentation summarizing a recent research report from the primary, behavioral-ecological literature.  Relevant research reports can be found in the specialized journals Behavioral Ecology, Behavioral Ecology and Sociobiology, Animal Behavior, Ethology, Journal of Ethology, Behavior, etc., but also in scientific journals such as Nature, Science, Proceedings of the National Academy of Sciences, Proceedings of the Royal Society of London, etc; all these journals are accessible as e-journals via the UT Library Online (http://www.lib.utexas.edu/journals/).  Students will be randomly assigned at the beginning of the semester to one of twelve behavioral-ecological topics, but students are free to trade topics between each other.  Undergraduate students will prepare their presentations in groups of two or three students (only one student needs to give the actual presentation); graduate students are expected to give their presentations individually.  A sample presentation will be given by the instructor at the beginning of the semester; this presentation could serve as a model, but students are encouraged to organize their own presentations creatively and in whatever way they think communicates their topic most effectively.  Students are expected to give their presentation as a PowerPoint talk, including images of the respective study organism, scanned figures or graphs from the research report, or other relevant visual material.  An e-file of the PowerPoint talk should be given (or e-mailed, if possible) to the TA two days in advance of the day of the presentation, and the students should be prepared to have a backup set of overhead transparencies ready in case of computer/PowerPoint problems. Students are encouraged to select a research report on non-human animals, humans, or even other organisms (e.g., plants, fungi, bacteria; if the particular topic applies to these organisms).  The twelve topics are:

(1)   direct reciprocity, indirect reciprocity (Sept 11 2003)                  

(2)   kin selection, reproductive skew (Sept 18 2003)             

(3)   eusociality (Sept 23 2003)                                  

(4)   symbiont choice, conflict within between-species mutualisms (Oct 2 2003)

(5)   levels of selection (Oct 9 2003)

(6)   sex-ratio allocation (relatedness asymmetry, local mate competition, etc)  (Oct 16 2003)  

(7)   parent-offspring conflict; infanticide & siblicide (Oct 23 2003)

(8) mating systems (Oct 28 2003)

(7) sexual selection (Nov 6 2003)

(10) female control, cryptic choice (Nov 13 2003)

(11) sexual conflict, sperm competition (Nov 20 2003)

(12) evolutionary psychology (Nov 25 2003)

 

Short Paper on Hypothesis Testing

A short paper (about two pages) on hypothesis generation and hypothesis testing in behavioral ecology will be assigned on Sep 4th and is due on Sep 18th.  A behavioral problem will be announced during the lecture of Sep 4th, and each student is expected to generate hypotheses to address the behavioral problem, then derive critical predictions for each hypothesis.  The nature of hypothesis generation and derivation of critical predictions will be explained during the lecture on Sep 4th. Students are expected to send their papers as Word documents via-e-mail to Prof Mueller by midnight on Sep 18th.  A duplicate copy of the paper also needs to be pasted into a separate e-mail message and sent to Prof Mueller by the deadline time.

 

Grant application

Each student is expected to prepare a behavioral-ecological grant application following the format of a Grant-In-Aid of Research from the Sigma-Xi Scientific Research Society.  The grant application should consist of three parts: (a) the proposal itself (maximum of 400 words), explaining relevant background information, the study question or hypotheses to be addressed, and the research methods; (b) a list of references; and (c) a research budget (not to exceed $1000).  Because of the word limit of 400 words, students are advised to draft their proposals carefully, preferentially asking other students to read their proposals for commenting, then revising proposals accordingly.  The proposal will be graded for both research merit and presentation (logical flow, language, succinctness, verbosity, etc.).  Specific guidelines for the grant application and a sample will be handed out at the beginning of the semester. The grant application is due (in hard copy) on Nov 18 at class time.

 

Grading

Three exams will be given during the semester.  Exams are non-cumulative, covering (with few exceptions to be announced) only the material of the course segment ending with the exam.  Discussion participation/attendance and the Forum presentation will also contribute to the overall course grade.  The student presentations will be graded according to overall group performance/creativity, as well as the relative contribution of each student to the presentation. 

15%     Exam 1

15%     Exam 2

15%     Exam 3

15%     Paper (2-3 pages; hypothesis testing)

10%     Student presentation (4 minutes)

15%     Grant application (400 words main text; references & budget)

15%     Discussion (5% attendance; 10% participation)

Because undergraduate and graduate students are enrolled in different courses, they will not be graded against each other.
