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.

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 Courses

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

Principal Courses (10, including breadth requirements)

Breadth Requirement Courses (4 courses):

  • Cell & Molecular Biology (CM)
    • CAS BI 206
  • Physiology and Neurobiology (PN)
    • CAS BI 315* or
    • CAS BI 325 (or NE 203*)
  • Ecology, Behavior, Evolution (EBE)
    • CAS BI 303* and
    • CAS BI 448

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

Additional principal courses (6) selected from the following:

  • CAS BI 225
  • CAS BI 260
  • CAS BI 302*
  • CAS BI 306*
  • CAS BI 307
  • CAS BI 309
  • CAS BI 407*
  • CAS BI 414
  • CAS BI 415
  • CAS BI 423
  • CAS BI 443
  • CAS BI 475
  • 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 543

Note: Among the additional principal courses, at least three 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, and a laboratory requirement.

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

Tropical Ecology Program (TEP)*:

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

Marine Semester (MS)*, students choose one course for each block:

  • CAS BI 531
  • CAS BI 539
  • CAS BI 546
  • CAS BI 550
  • CAS BI 563
  • CAS BI 569
  • CAS BI/GE 523
  • CAS BI/GE 578
  • CAS ES 543
  • CAS ES 557
  • CAS MR 510
  • CAS MR 533

*Note: Students must apply and be accepted into the TEP and MS to take the courses listed above. TEP and MS courses fulfill 4 of the 6 additional principal biology courses and satisfy the biology concentration requirement of three courses at the 300–500 level, and three courses with a laboratory or field component.

Undergraduate Research Options

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 and do not count toward the major.

To receive credit toward the major, research must be done on an approved topic in courses open to juniors and seniors. 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).

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

Prerequisite and Corequisite Chemistry Courses

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

Standard (recommended) track:

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

Alternative track (not for students interested in medical school or other health-related professions):

  • CAS CH 171; plus
  • CAS CH 174; plus
  • 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. Most biology majors elect to take a fourth semester of chemistry, CAS BI 204 (or 212 or 214), which is a requirement for medical and other professional schools.

Required Mathematics or Mathematics/Computer Science Courses

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

Calculus Courses:

  • CAS MA 121
  • CAS MA 122
  • CAS MA 123
  • CAS MA 124
  • CAS MA 196
  • CAS MA 127
  • CAS MA 129

Note: Only one of CAS MA 121 and 123 can be taken for credit; similarly, only one of CAS MA 122, 124, 127, or 129 can be taken for credit.

CAS MA 127 or MA 129 satisfies the two-course mathematics or mathematics/computer science requirement for this major.

Statistics Courses:

  • CAS MA 115
  • CAS MA 116
  • CAS MA 213
  • CAS MA 214
