Biological Sciences B.S. – Ecology and Evolutionary Biology Concentration

Program Overview

College of Natural and Health Sciences

Contact: Scott Franklin, Ph.D., Department Chair

Location: Ross Hall 2480

Telephone: 970-351-2921

Website: www.unco.edu/nhs/biology

Advising Information:

Students must consult with their assigned major advisor each semester prior to registering.

To find your advisor, log into ursa.unco.edu; go to 'Student' tab and click 'View Student Information' link. If no advisor is listed, contact the major program for advisor information.

In accordance with University Policies, coursework earned more than 10 years prior to the date of matriculation to UNC may not be used to satisfy any major or minor requirements. Any exception to this policy is at the discretion of the academic program. The school's transfer advisor can be reached at 970-351-2921.

The program consists of three parts:

  1. Liberal Arts Curriculum (LAC) Credits
  2. Required Major Credits
  3. University-Wide Credits

Program Description:

This concentration focuses on organismal biology and on field courses. Students completing the program will acquire a background in taxonomy, the diversity of species, and life histories. Students should have an interest in working with plants and animals in a field setting. Undergraduates entering this program should have a strong interest in Biological Sciences and have completed general high school science and mathematics requirements. Given the technical nature of some required courses, additional preparatory coursework may be required for students with limited previous STEM experience. Students will be prepared to work for public or private sector environmental agencies such as state or federal wildlife agencies, the Bureau of Land Management, the National Park Service, various parks and recreation programs or private consulting agencies.

They can also continue their education in graduate programs in the pure or applied biological sciences (botany, zoology, ecology, forestry, wildlife biology).

Program Admission Requirements:

Academic Good Standing

Program Requirements:

The State of Colorado has mandated that institutions of higher education assess student outcomes resulting from their college education. The School of Biological Sciences requires that all undergraduate students entering under this Catalog meet the following conditions in addition to meeting the graduation requirements of the University:

  • In the senior year of study all undergraduates will take a standardized assessment administered by the School of Biological Sciences to assess the effectiveness of the curriculum.
  • Junior and seniors with a cumulative GPA of 3.00 or higher are permitted to take 500-level courses. Any 500 level BIO prefix courses will be applied to Biological Science Advanced Study requirements. Consult with faculty advisor to ensure courses are appropriate.
  • NOTE: Students completing a major in Biological Sciences and a minor in Chemistry are exempt from the university policy that a maximum of 12 credit hours can be shared between a major and minor. A student must still complete a minimum of 6 upper-division UNC credits (300-400) or UNC approved Study Abroad credits in the minor.

Degree Requirements — 120 Credits
