Program Description

Students begin their study of biology at Bucknell by taking four core courses that introduce the primary areas of biological investigation with basic laboratory techniques. A wide variety of advanced classes, research opportunities, and an active seminar program complete the students' course of study.

Once their core courses are completed, students are encouraged to participate in the biology department's research program in which they conduct research under the direct supervision of one of the faculty members for course credit. The research, done at a highly professional level, often results in articles that are co-authored by students and published in professional journals.

Special facilities for research at Bucknell include equipment for liquid scintillation counting, electrophoretic separation of DNA and proteins, cell culture, DNA synthesis, polymerase chain reaction, spectrophotometry, ultracentrifugation, and high performance liquid chromatography. In addition, Bucknell has a large greenhouse, containing research and demonstration areas and housing an herbarium collection of 20,000 plant species. The University also has a 65-acre Natural Area, located 12 miles from campus along the Chillisquaque Creek. Bucknell also is affiliated with the Woods Hole (Massachusetts) Marine Biological Laboratory and with the Archbold Biological Station in Lake Placid, Florida.

Bucknell's biology faculty believes that scientists benefit from the exchange of ideas. The seminar program brings students and faculty together to discuss research in progress or to hear talks by visiting scientists. Students engaged in summer research, in the honors program, or conducting research for their master's degree present seminars as well.

The biology professors at Bucknell are teacher-scholars. Not only are they active, enthusiastic teachers; they are researchers with international reputations. They have received research grants from the National Science Foundation, the National Institutes of Health, the National Institutes on Drug Abuse, and the National Institute of Child Health and Human Development.

Of the 70 to 80 biology graduates each year, most go on to professional schools--primarily medical, but also dental, veterinary, and law. A few earn their doctorates in biology at larger institutions. Bucknell's biology program leads to a bachelor of science or a bachelor of arts degree, depending on students' needs. Graduate students may earn either a master of science or a master of arts degree in biology.

Degree Requirements

The major in biology may be earned in either the bachelor of science or the bachelor of arts program.

The major in biology in the bachelor of arts program requires eight courses in biology: the core sequence of BIOL 205, 206, 207, and 208, which must be completed by the end of the third year, and four 300-level or above electives (only one of which may be BIOL 399). At least one of the four electives must be in each of the two following areas (see below).

The major in biology in the bachelor of science program requires nine courses in biology: the core sequence of BIOL 191, 201, 202, 203, and five additional 300-level biology courses. At least one of these electives should be in each of the two following areas:

Students who successfully complete BIOL 121-122 and wish to major in biology may receive core credit pending consultation with the department.

All students with a major in biology are required to take CHEM211-212. Students in the bachelor of arts curriculum must complete the CHEM 211-212 sequence by the end of the sophomore year. Bachelor of science students will take CHEM 211-212 during their first year. Students are required to take one year of mathematics: MATH 201 (Calculus I) and MATH 216 (Applied Statistics). Bachelor of science students will also take one year of physics (PHYS211-212) and two additional courses in major-related areas. Any two of the following courses will satisfy this requirement, although a second year of chemistry or MATH 202 is generally recommended: CHEM 221, 331, 340, 351, 352; CSCI 203, 204; GEOL 103, 104, 106, 205, 213, 305, 310; MATH 202, 211, 217; PHYS 221; PHIL 220; PSYC 250; ANBE/BIOL/PSYC 266; ANBE/PSYC 366.. Other courses may be substituted with department approval.

Students interested in pursuing work beyond the undergraduate degree are encouraged to elect MATH 217 (Statistics for the Biological Sciences and/or MATH 202 Calculus II and consult their academic advisor or premedical adviser. Transfer students must complete at least four courses in biology in residence at Bucknell, only one of which may be BIOL 399.

A minor in biology consists of five courses. Two of the five courses must be selected from among the following introductory level courses: BIOL 121, 122, 205, 206, 207 and 208. At least two of the courses must be 300-level courses, exclusive of BIOL 399.

Capstone Experience (CP)

Each student in the College of Arts and Sciences must satisfy the requirement of a Capstone course or an equivalent experience, usually in the senior year after all distribution requirements have been completed. The goal of the Capstone Experience is to provide opportunities for students to: (1) synthesize and integrate knowledge within and across disciplines; (2) reflect and evaluate their entire educational experience, as well as to examine the process of integration and reflection itself; (3) make connections between the topic of focused study and real-world problems and questions that will continue to engage them after they leave Bucknell; and (4) interact with students who have different perspectives in order to foster a collaborative approach to learning and creative problem-solving that will carry over into their future lives.

Capstone courses may be interdisciplinary seminars open to all Arts and Sciences students or they may be offered by individual departments or groups of departments for their own majors. In all cases, they are small seminars of approximately 15 students in order to ensure maximum participation and interaction among class members.

Honors Thesis Program

Students who have a GPA of 3.5 or better may choose to pursue an honors thesis. A proposal is due by October 15 of the student's senior year, with completion and defense of the thesis in May. Interested students should see relevant faculty members.

Affiliated Programs

Students interested in environmental aspects of biology may wish to review the description of the Environmental Studies Program.

Students interested in molecular aspects of biology may wish to review the description of the Cell biology/Biochemistry Program.

Students interested in the behavioral aspects of biology may wish to review the Animal Behavior program.

Masters Program

Applicants for admission should have credit for a minimum of eight courses in biology or supporting disciplines (chemistry, physics, mathematics, etc.) with a grade point average of 3.0 in these courses, although exceptions may be made for students showing marked improvement during their undergraduate program or demonstrating exceptional aptitude or achievement. Applicants must submit both aptitude and advanced test GRE scores. All incoming graduate students are required to pass a course in statistics or biostatistics unless they have already passed such a course as an undergraduate. See the Graduate School for more details.

Eight courses are required for the master's degree; added work may be required of students whose undergraduate program is too narrow or limited. In such cases, the student must achieve the equivalent of a B.S. or B.A. degree in biology from Bucknell University. At least five of the eight courses must be in biology, and all must be at the 600 level. A cumulative grade point average of 3.0 is required, and not more than two courses of C work will be accepted toward the degree.

Facilities are available for graduate research in several areas of biology. Laboratories are well instrumented for graduate research in drug metabolism, glycoprotein synthesis, spermatogenesis, genetics, immunobiology, plant physiology, molecular biology, and developmental biology. Recently, an electron microscopy laboratory was established. Extensive research projects in evolutionary biology and ecology are underway at Bucknell. Facilities are available for research in population genetics, fire ecology, primary productivity of streams and lakes, resource allocation in plant communities, and predator-prey studies of marine invertebrates.
