About the Program
This major investigates how organisms interact with their physical environment and other organisms, from an evolutionary perspective. Ecologists’ work includes research and/or teaching involving population genetics and evolution, adaptive strategies for survival, the nature of populations, and community ecology. Ecologists also offer technical services in connection with environmental impact decisions and regional planning, and environmental education at various levels as teacher, naturalist, or journalist. Common career paths for undergraduate students include graduate study leading to academic positions (research and teaching in small colleges and major universities), technical positions in industry (mostly dealing with environmental assessment), and employment in state and federal environmental agencies.

Degree Requirements
120 Credits RequiredCurriculum and Degree Requirements for College of Science
A College of Science degree is conferred when a student successfully completes all requirements in their degree program. Students will complete coursework or approved experiential learning activities to meet the following three degree components:
- Major
- Science Core Curriculum
- Electives
Students may use any of the following options to meet College of Science degree requirements:
- Purdue Coursework
- AP, IB, and CLEP credit. The use of AP and IB coursework varies between College of Science degree plans.
- Transfer Credit. Students should consult the Admissions Transfer Credit Resource page for all available transfer options.
College of Science degree programs vary widely in their approval and use of the proceeding options and thus students are strongly encouraged to work closely with their academic advisors and to regularly consult their MyPurduePlan to view the use of each option in their degree plan.
Most College of Science degree programs contain elective credits students may use to pursue courses that relate to their interests or which support their major area of study. The elective area of a degree plan may also be used to complete minors, second majors and certificates such as the Entrepreneurial Certificate. With the exception of courses on the No Count List, any Purdue course may be used to meet the elective area of a student’s degree plan.
College of Science Core Requirements
All Students starting Purdue University Fall semester, 2007 or later are required to pursue the 2007 Science Core curriculum.
The College of Science Core Curriculum requires the completion of approved coursework and/or experiential learning opportunities in the following academic areas:
Earning Core Curricular Requirements through Experience
Students may meet selected core curriculum requirements through approved experiential learning opportunities. Interested students should contact their academic advisor for more information on this option and incorporating experiential learning into their four-year program of study. For more information on earning requirements through experience, please click here.

Prerequisite Information
For current pre-requisites for courses, click here. World Language Courses
World Language proficiency requirements vary by program. The following list is inclusive of all world languages PWL offers for credit; for acceptable languages and proficiency levels, see your advisor. (ASL-American Sign Language; ARAB-Arabic; CHNS-Chinese; FR-French; GER-German; GREK-Greek(Ancient); HEBR-Hebrew(Biblical); HEBR-Hebrew(Modern); ITAL-Italian; JPNS-Japenese; KOR-Korean; LATN-Latin; PTGS=Portuguese; RUSS-Russian; SPAN-Spanish) Critical Course
The ♦ course is considered critical.
In alignment with the Degree Map Guidance for Indiana’s Public Colleges and Universities, published by the Commission for Higher Education (pursuant to HEA 1348-2013), a Critical Course is identified as “one that a student must be able to pass to persist and succeed in a particular major. Students who want to be nurses, for example, should know that they are expected to be proficient in courses like biology in order to be successful. These would be identified by the institutions for each degree program”.
Disclaimer
The student is ultimately responsible for knowing and completing all degree requirements.
Consultation with an advisor may result in an altered plan customized for an individual student.
The myPurduePlan powered by DegreeWorks is the knowledge source for specific requirements and completion.
