Graduate Concentration in Ecology and Evolution: Ph.D. Policy and Curriculum

The prospective student must meet all of the requirements for the Ph.D. degree in the Department of Biological Sciences, as shown in the departmental Graduate Program Policy. In addition to the departmental requirements, the specific curriculum required for the Ecology and Evolution concentration, for Ph.D. students is:

Graduate Curriculum

Notes

1. One year of graduate level statistics, specific courses to be decided in consultation with the major advisor (core).
2. Ph.D. students are required to complete two research tutorials whose structure will depend on the nature of the research project.
3. BISC 827 - Graduate Seminar is required every fall and spring semester. Students will present oral summaries of their laboratory tutorials or ongoing research.
4. All Ph.D. students are required to serve at least two semesters as a teaching assistant. In most cases, this will occur during the first year in the program.
5. Ph.D. students are expected to devote full time effort during winter term of the first year in a laboratory tutorial that they will register for during spring.
6. Students are expected to spend winter and summer sessions in full time research towards the thesis.
7. Courses at University of Delaware that currently meet this requirement are BISC 656 - Evolutionary Genetics, and CHEM 647 - Biochemical Evolution.
8. In consultation with the Advisement Committee, students may elect to take other graduate level courses appropriate to their degree program. These may include but are not limited to: BISC 641 - Microbial Ecology, BISC 660 - Environmental Physiology, ENWC 814 - Advanced Ecology and ENWC 620 - Behavioral Ecology, and a graduate level course in molecular methods.
9. Students must enroll in BISC 801 - Seminar in Ecology and Evolution whenever it is taught.

If any graduate courses equivalent to those listed above have been taken in previous graduate degree programs and have been accepted as graduate level transfer credit by the University, the transferred courses may be used to satisfy the Concentration requirements with the approval of the Concentration coordinator.

Other courses in addition to those listed above may be taken upon the advice of the student's advisor and dissertation committee, but these will not substitute for approved electives.

The Preliminary Examination

Procedure

Students will be provided with at least four sets of papers from the primary literature selected by faculty from which they must choose one set as the basis for their oral examination. These papers will be available at least six weeks before the exam, usually no later than May 1 [for students admitted in the summer or fall], so that the exam can be administered the second or third week of June. Students admitted in the Spring will usually have paper sets available by December 10 so that the exam can be administered in late January. Four weeks prior to the exam, the student should inform the Concentration coordinator of the chosen paper set and arrange the time of the exam. Prior to the exam, the student should prepare transparencies of all of the figures and tables presented in the papers so that they will available for discussion during the exam.

During the exam, the student will be tested by a committee of four to six faculty on his/her comprehension of all aspects of the paper including background and related information. Students present a 10 minute synopsis of the primary paper, then the examination committee will ask questions pertaining to the paper's background material, methodology, experimental results and their significance, the article's overall significance to the field as well as field specific topics. It therefore is imperative that the student searches and reads the literature for background and related information. While a good starting point is the bibliography at the end of the chosen paper set, it is likely that other primary literature sources will need to be consulted. Prior to the exam, students are encouraged to contact faculty to discuss the topics they are responsible for and to clarify difficult concepts.

Grading

After the oral examination, the examination committee will determine an appropriate grade. Four grades are possible at the initial exam: unconditional pass, conditional pass, re-examination or failure. If the student receives an unconditional pass, the exam was completed satisfactorily and no conditions are applied. In a conditional pass, the student performed marginally in one or more areas and may be asked to complete (with a grade of B or better) one or more courses as a condition for changing the grade to pass. The examination committee may prescribe conditions in addition to, or in lieu of, course enrollment. Once the condition is fulfilled, the student is responsible for informing both the Biology Graduate Program Director and the Concentration Coordinator so that the grade can be changed officially. If the student receives a re-examination, the student's performance was unsatisfactory and the exam should be repeated within three months, but no later than six months after the initial examination. Only one retake will be permitted. This would normally be prior to the start of the fall semester for June examinations, and during Spring break for January examinations. If the student receives a failure, the student's performance strongly indicated an inability to complete an independent research project and the student will be terminated from the Ecology and Evolution concentration without the possibility of a retest. If the student does not perform satisfactorily in a re-examination, the student will be terminated from the Concentration in Ecology and Evolution and recommended to the Graduate Affairs Committee for dismissal from the graduate program.

Once the student passes the preliminary examination, he/she becomes eligible to sit for the qualifying examination.
