BA in Biology—Ecology & Conservation Biology Specialization

With global climate change accelerating and conservation issues arising worldwide, an understanding of ecology, ecosystems, and the measures needed to sustain Earth’s life-support systems has become increasingly important. The Biology major with a specialization in Ecology & Conservation Biology (ECB) is designed for students seeking a greater depth of training in this critical area of contemporary biology. Advanced electives in biology may be selected from a broad range of courses including ecology, evolution, animal behavior, plant biology, and marine biology. This specialization provides students with a sound conceptual framework as well as hands-on experiences in ecology and conservation biology, preparing them for graduate study in the environmental sciences and careers in academia, government, or the private sector.

Requirements

The requirements for the Specialization in Ecology & Conservation Biology major include two introductory biology courses, ten principal courses (including breadth requirements), and seven related chemistry, mathematics/computer science, and physics courses.

After introductory biology, three courses must be lab courses taken in the Biology Department. One semester of 4-credit independent research may be used toward the three-lab requirement.

Students must earn a grade of C or higher in all biology, mathematics, and physics courses. A grade of C– or higher is required for credit in the prerequisite and corequisite chemistry courses.

Course titles and full descriptions are located in the Courses portion of this Bulletin. Unless otherwise noted, all courses are 4 credit hours.

Introductory Biology (2 courses)

  • CAS BI 107 (or CGS NS 201)
  • CAS BI 108

Breadth Requirement (1 course)

Physiology and Neurobiology (PN)

  • CAS BI 315* or
  • CAS BI 325 (or NE 203*)

Foundation Courses (3 courses)

  • CAS BI 206 (or BI 216)
  • CAS BI 303*
  • CAS BI 448

*Course will also satisfy one of the three lab requirements.

ECB Electives (6 courses)

Choose six courses from the following list:

  • CAS BI 225
  • CAS BI 260
  • CAS BI 302*
  • CAS BI 306*
  • CAS BI/GE 307
  • CAS BI 309
  • CAS BI 407*
  • CAS BI 411
  • CAS BI 414
  • CAS BI 415
  • CAS BI/ES 423
  • CAS BI/ES 443
  • CAS BI/GE 475
  • CAS BI 486
  • CAS BI 502
  • CAS BI 503
  • CAS BI 504
  • CAS BI 506
  • CAS BI 508
  • CAS BI 512*
  • CAS BI 513*
  • CAS BI 515
  • CAS BI 519*
  • CAS BI 530
  • CAS BI/NE 542
  • CAS BI 543

Note: After introductory biology, at least three courses must be at the 300–500 level, and three must have a laboratory or field component. A 300–500-level course with a laboratory simultaneously counts as one of the biology courses beyond BI 107 & 108, a 300–500-level course, and a laboratory requirement. Nonetheless, it is still counted as a single course toward fulfillment of the major.

*Course will also satisfy one of the three lab requirements.

Tropical Ecology Program (TEP)*

The Ecuador Tropical Ecology Program is offered every Fall and Spring Semester. The program consists of four ecology courses based on field research:

  • CAS BI/GE 438
  • CAS BI/GE 439
  • CAS BI/GE 440
  • CAS BI/GE 441

Please check the Study Abroad web page for prerequisites and other details of the Tropical Ecology Program.

Marine Semester (MS)*

The Marine Semester is offered every Fall Semester. Students are required to select one course during each of four “blocks.” Each block comprises 18–20 class days.

Please check the Boston University Marine Program (BUMP) Bulletin page for an updated list of MS courses. Students may also refer to the BUMP website for additional information about the Marine Semester.

*Note: Students must apply and be accepted into the TEP to take the TEP courses listed above. TEP and MS courses fulfill all 4 additional electives and satisfy the biology major requirements of three courses at the 300–500 level, and three courses with a laboratory or field component.

Undergraduate Research Options

While research is not required by the major, undergraduate students are encouraged to participate in research during their time at Boston University. Research for credit courses require students to submit an application and receive approval by the Director of Undergraduate Studies.

Freshmen and sophomores may take CAS BI 191/192 or BI 291/292 may be taken for elective credit by freshmen and sophomores, respectively; these courses may only be taken for 2 credits per semester. These courses will not count toward the major.

Juniors and seniors may take CAS BI 391/392 and BI 491/492 for 4 credits toward the major. A maximum of 8 credits (two courses) from the following courses may be counted as additional principal biology courses, but no more than 4 credits (one course) will apply toward the laboratory requirement. Students do not need to take two consecutive semesters of research to apply 8 credits toward the major (ex. students can take CAS BI 391 and BI 491 and apply all 8 credits toward the major). A total of 12 credits of directed study may be applied toward graduation credits.

  • CAS BI 391/392
  • CAS BI 401/402
  • CAS BI 491/492

Honors Research in Biology (CAS BI 401 & 402) requires an overall GPA of 3.0 and a Biology GPA of 3.5. Students must complete two semesters of research and one semester of the Honors Seminar (CAS BI 497/498). Honors Research requires completion and defense of a written senior thesis.

Please visit the Biology Department website for additional information regarding undergraduate research opportunities and instructions on how to apply for credit.

Required Related Science Courses (7 courses)

Chemistry

Three courses in chemistry are required for the biology major and may be chosen from the following tracks:

Standard (recommended) track:

  • CAS CH 101 & 102 (or 109 & 110 or 111 & 112);
  • CAS CH 203 (or 211)

Alternative track (will not fulfill requirements of medical school or some other health-related professions):

  • CAS CH 171;
  • CAS CH 174;
  • CAS CH 273

Note: It is recommended that CAS CH 101/102 (or 171/174) be taken concurrently with CAS BI 107/108 freshman year, if possible. CAS CH 203 (or 211 or 273) is a corequisite for CAS BI 203 and a prerequisite for CAS BI 206. For medical and other professional school admission, biology majors elect to take a fourth semester of chemistry, CAS CH 204 (or 212 or 214), as well as biochemistry.

Mathematics/Computer Science

Two courses in mathematics (calculus or statistics) or one course in mathematics and one in computer science, from the list below:

Calculus Courses
