Recommended First-Year/Sophomore Preparation

Students contemplating a major in biology should plan to take BIO 110 in the fall of 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. In the fall of either the sophomore or the junior year, students should plan to take CHE 241. BIO 210 and BMB 210 (in either order) should be completed no later than the end of the junior year. In addition to these required courses, prospective majors are strongly encouraged to enroll in one or more 200-level biology courses during their first and sophomore years. 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.


Requirements for the Major

BIO 110, 210;
BMB 210;
CHE 131and 132, or CHE 135;
CHE 241;
PHY 110;
BIO 310 or 320 or BIO 330, 340, 360, 370, 500;
Two additional BIO courses numbered 300 or higher. BMB 310, 320, 330, and 340, and PYB 320 and 330 may also be used to fulfill this requirement. However, at least ONE of the two courses must be a BIO course;
One term of math is required, which can be satisfied by taking MAT 130, MAT 140, MAT 170, or CSC 117. Students who place in MAT 171 or higher at entrance are not required to complete any course work in math.
Since most graduate programs expect some background in calculus, at least one term of calculus is strongly recommended for those planning to major in biology.


Requirements for the Minor

A minimum of 23 credit hours chosen to include BIO 110, BIO 210, BMB 210, CHE 131or 135, and three BIO courses numbered 300 or above. Appropriate BMB or PYB courses may be substituted with approval of the Biology Program Committee.


Biology Courses

BIO 110 The Unity and Diversity of Life (four credit hours)
An introduction to biology through the integrating theme of evolution. The first half of the course develops the foundations of biological unity: cell structure and function, bioenergetics, and genetic control. The last half of the course begins with a survey of the major groups of organisms illustrating the diversity of life. After a brief introduction to formal principles of evolution responsible for the origin of this diversity, the course concludes with a grounding in ecological relationships which govern survival at all levels of biological organization.

Prerequisite: BIO 110.

BIO 320 Natural History of Vertebrates
The life histories and adaptations of vertebrates are studied with an emphasis on the origins and evolution of the modern classes. Adaptations of vertebrates to the opportunities and constraints imposed by aquatic versus terrestrial conditions are examined. Special consideration is given to aspects of vertebrate biology that are of particular relevance to the human condition. Prerequisite: BIO 110.

BIO 325 Vertebrate Morphology
(four credit hours)
The structure of vertebrate organ systems is studied through lectures and lab dissections. The phylogeny of vertebrates is traced through consideration of the adaptation of organ systems to specific environmental requirements. A weekly lab is required. Prerequisite: BIO 110.

BIO 330 Entomology
An introduction to the biology of insects. This course focuses on the morphological adaptations, life history strategies, behavior, ecological and evolutionary relationships, and diversity of insects. Prerequisite: BIO 110.


BIO 335 Developmental Biology

A survey of terrestrial ecosystems and a discussion of human influences on ecological systems are also included. Weekly laboratory required. Prerequisites: BIO 110 and BIO 210.

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.

BIO 375 Conservation Biology
A study of the protection and restoration of threatened organisms and ecosystems using ecology, genetics, and theoretical modeling.

Prerequisite: BIO 110, or NSC 120 with permission of the instructor.

BIO 455 The Biology of Viruses
