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 specialization in Ecology & Conservation Biology requires a total of 12 biology courses (introductory, foundation, breadth, and elective courses). Students must also complete a total of six to seven related courses in chemistry, mathematics/computer science, and physics.

Beyond Introductory Biology, at least three major courses must be at the 300+ level and three major courses must be lab courses taken in the BU Biology Department (the 300+ and lab requirements can overlap).

A grade of C or higher is required for major credit in all courses except corequisite chemistry courses. A grade of C– or higher is required for major credit in 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.

* Course will also count toward the three-lab requirement.

^ GE 101 is a prerequisite for BI 307 and BI 475.

Note: After introductory biology, a minimum of five courses must be taken in the BU Biology Department (i.e., have a CAS or MET BI or BI cross-listed course designation). A maximum of 4 MET courses may be counted as credit toward the BA degree. In addition, at least three courses must be at the 300+ level and three must have a laboratory component. Some of these requirements can overlap (e.g., BI 315 simultaneously counts as a breadth requirement, a 300+ level course, and as a lab toward the three-lab requirement). Nonetheless, it is counted only as a single course toward fulfillment of the major.

Related Requirements (6–7 courses)

Chemistry

Choose one of the following tracks (in consultation with your major advisor):

Standard Track (recommended):

Choose one of the following general chemistry sequences:

Sequence I Sequence II Sequence III
CAS CH 101 &
CAS CH 102 (or CH 116)
CAS CH 109 &
CAS CH 110
CAS CH 111 &
CAS CH 112

AND

  • Choose one of the following organic chemistry courses: CAS CH 203 (or CH 211 or CH 218)
Alternative Track (not acceptable for most pre-health careers):
  • CAS CH 171^
    ^ Or any completed general chemistry sequence from the standard track

AND

  • CAS CH 172 or CH 174

Note: It is recommended that the standard track general chemistry sequence (or alternative track’s CH 171 & 172 or CH 171 & 174) be taken concurrently with BI 107 and BI 108 during freshman year. Most Biology majors complete the standard track and continue onto a fourth semester of chemistry (CH 204 or 214), which is a requirement for medical and other professional schools. Students contemplating application to medical school are also advised to take biochemistry (CAS BI 421/422 or CH 373) in their junior or senior year.

Undergraduate Research in Biology

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