Biology

Division of Science and Mathematics


The discipline of biology encompasses many subject areas ranging from the study of molecular and cellular functions to the ecological interactions among organisms. As biology majors, students gain a solid background in the discipline while also gaining the ability to apply biological principles to our world. Students planning on majoring in biology prepare for the major with appropriate courses in mathematics, chemistry, and physics. In their first two years, students are introduced to the breadth of the discipline in three core courses that provide a foundation in biological diversity, ecology, evolution, genetics and cell biology.  Upon declaration of the major, students build upon this foundation by choosing one course from each of the following areas:  cell and molecular biology, organismal biology, and ecology and evolution. Three additional elective courses from these areas or from a select number of courses in other major programs allow the student to craft a major reflecting his or her personal interests. At the senior level, our majors enroll in the capstone senior seminar course.

Recommended First-Year/Sophomore Preparation

Students contemplating a major in biology should plan to take BIO 110 in their first year. CHE 131 and CHE 132 may be taken during either the first year or the sophomore year. For those who qualify, CHE 135 may substitute for both CHE 131 and 132. Normally, students should plan to take BIO 210 no later than the spring of their sophomore year. CHE 241 and BMB 210 should be completed no later than the fall of the junior year. Any prospective biology major with specific graduate/pre-professional school goals should consult with a member of the biology faculty (or one of the specific pre-health careers advisors) early in the student’s academic career to determine both the types of courses that should be taken and the specific terms in which these courses should be taken to best attain the post-graduate goals. See the health professions advisory committee's website for more details.

Requirements for the Major*

Foundation Courses (normally completed in the first and sophomore years)
BIO 110, 210; BMB 210; CHE 131 and 132, or CHE 135; CHE 241; MAT 130; PHY 110 or CSC 117 or CSC 261

Students planning to attend graduate school in biology should take at least one calculus course. Additional math, chemistry, physics and computer science courses are also recommended for graduate school. Many professional schools (e.g., medical, dental) require calculus and additional chemistry and physics courses.

Upper-level Courses (normally completed in the junior and senior year)
A minimum of seven upper-level biology courses are required for the biology major. The seven courses must be selected according to the following criteria: One course from each of the following groups (A, B, and C):

BIO 253/453 Malaysian Borneo: Biodiversity & Conservation
Borneo is a mysterious land, rich in culture and unparalleled biological diversity, yet human activities have brought about rapid and dramatic change in landscape composition that threatens the very existence of this
natural wealth. This two‐week trip to Sarawak, Malaysian Borneo will introduce students to the third largest island and most biodiverse region on the globe. Daily hiking expeditions and an extended camping trip will target pristine tracts of tropical forest and a rugged terrain rich with natural formations and endemic species including organisms like orangutans, giant stick insects, and plants that produce the world's largest flowers. Using both scientific and ethical perspectives we will work to understand the natural history of Borneo, and ascertain the short and long‐term impacts of human activities that are rapidly altering the landscape composition. Good physical fitness is required, as much of our time will be spent hiking over rough
terrain and in challenging conditions. Prerequisite: One of BIO 110, BIO 210, ENS 210, or permission from instructor.

BIO 265 Biology, Databases and Research (one credit hour)
This course will introduce students to the way in which a biological database can be used as a research tool. The publically accessible PTAGIS database contains 15 years of data associated with the movement of juvenile and adult salmon in the Columbia River Basin. The database tracks the movement of these fish through the PIT (passive integrated transponder) tags inserted during the juvenile life stage. Students enrolled in this class will learn how to use this database, will develop a specific research question that can be addressed by using the database, and will collect and analyze data from the database to answer their individual research questions. Prerequisite: BIO 110; MAT 130 or strong quantitative background recommended.

BIO 280  Into the Great Abyss: Cave Ecology
Caves have long had a profound hold on the human psyche. Whether functioning as the spiritual ‘doorway to the underworld,’ a place of habitation, a philosophical allegory, or a recreational thrill, caves have played a dynamic role in our lives and in the lives of countless other organisms. This course will begin by reviewing human interaction with caves over time and will transition to our modern understanding of the geology behind cave formation. We will then extend our scope beyond humans and work to understand how and why certain organisms call caves ‘home.’ Our analysis will highlight evolutionary processes that have lead to exhilarating and often peculiar adaptations found in organism that live in or near caves. We will also address current topics in cave biology including their use for studies of global climate changes and pervasive problems associated with human interference in these delicate ecosystems. This course will feature multiple field trips to local caves including Carter Caves and Mammoth Caves. Many of these field trips may extend into the evening, the weekend, and/or will require overnight accommodations.  Some physical restrictions may limit the ability of a student to participate in caving tours. Prerequisite: BIO 110 with preference given to BIO/BMB majors.

BIO 371 Behavioral Ecology: Avian Reproductive Strategies
An exploration of the reproductive strategies employed by birds, including studies of territoriality, courtship, mating success, sexual selection, mating systems, parental care patterns, alternative reproductive strategies, and cooperative breeding. These topics will be placed in an evolutionary context. How do different reproductive behaviors evolve? Why do some reproductive behaviors work in some environments but not in others? How does the distribution of resources influence reproductive behavior? In order to understand some of these avian behaviors, we will learn some special adaptations and physiology/morphology of the class: Aves. And to put this into a broader context, we will occassionally compare avian behavior to that observed in other taxonomic groups. In our investigations, we will utilize observation, manipulative experiments, game theory and optimization models. We will call upon the disciplines of ecology, evolution, physiology, developmental biology, and genetics. Students completing this course will come away with an understanding of how an avian behavioral ecologist goes about asking questions and designing experiments. Prerequisite: BIO 110 and 210.
