3.00 Credits
A biological survey of the vertebrates including aspects of morphology, physiology, behavior, ecology, and evolution. Issues of conservation and biodiversity will also be addressed. Laboratories will focus on the field biology of Pennsylvania vertebrates and on dissections to emphasize comparative anatomy. Three hours of lecture and one four-hour laboratory per week. Prerequisites: BIO 110 and 111. Alternate years.
-
3.00 Credits
A survey of fundamental principles in neurobiology, including the cell biology of the neuron, action potentials, synaptic transmission, organization of sensory and motor systems, neuronal development and pathfinding, and plasticity in the nervous system. Students will also explore neurological disorders such as Alzheimer's and Parkinson's diseases, depression, addiction, and problems with learning and memory. Includes student discussion and presentation of original scientific literature. Three hours of lecture and one three-hour laboratory per week. Prerequisites: BIO 110 and 111. Alternate years.
-
3.00 Credits
An investigation of different herbivorous animals, plant defenses, and how herbivores influence plants. Topics include evolution of herbivores and plants, effects of herbivory on individuals and communities, and types of plant defenses. We will also discuss how animals deal with plant defenses, the advantages and disadvantages of monophagous and polyphagous lifestyles, different types of herbivores and herbivore damage, and mutualisms between plants and their herbivores. Three hours of lecture and one three-hour laboratory per week. Prerequisites: BIO 110-111, or consent of instructor. Alternate years.
-
3.00 Credits
A study of the development of vertebrates from fertilization to the fully formed fetus with an emphasis on the role of gene expression in embryo and organ development. Laboratory will include such topics as chick embryo and zebrafish development and micro-injection techniques. Three hours of lecture and one three-hour laboratory per week. Prerequisites: BIO 110 and 111. Alternate years.
-
3.00 Credits
A study of causation, function, evolution, and biological significance of animal behaviors in their normal environment and social contexts. Three hours of lecture and one four-hour laboratory each week. Prerequisites: BIO 110-111. Alternate years.
-
4.00 Credits
An introduction to the study of viruses. The course will cover virus anatomy and reproduction, diseases caused by viruses, modern treatments of viral infections and viral vaccines produced by recombinant DNA and other technologies. Course content will also include a description of how viruses are used as tools for genetic engineering and for studying cellular processes like membrane signal transduction, regulation of genetic expression and oncogenesis (cancer). Four hours of lecture per week. Prerequisites: BIO 110-111 or consent of instructor. Alternate years.
-
3.00 Credits
The course introduces concepts concerning how pathogens cause disease and how host organisms defend against infectious diseases. Characterization of and relationships between antigens, haptens, and antibodies are presented. Other topics include: immediate and delayed hypersensitivities (i.e. allergies such as hay fever and poison ivy), immunological renal diseases, immunohaematology (blood groups, etc.), hybridoma technology, the chemistry and function of complement, autoimmunity, and organ transplant rejection phenomena. Laboratory experiments include: agglutination, immunoprecipitations, ELISA assays, immunofluorescence, immunoelectrophoresis, complement fixation, and Western blotting. Three hours of lecture, one three-hour laboratory per week. Prerequisites: BIO 110-111. Alternate years.
-
2.00 - 3.00 Credits
This course begins with a survey of the role of the endocrine hormones in the integration of body functions. This is followed by a study of the control of hormone synthesis and release, and a consideration of the mechanisms by which hormones accomplish their effects on target organs. Two three-hour lecture/laboratory periods per week. Prerequisites: BIO 110-111. Alternate years.
-
1.00 Credits
This course offers the student a chance to become familiar with research in the biological sciences using techniques such as meeting and talking with active researchers, reading and critically analyzing the current literature, and discussing the ideas and methods shaping biology. Students will be required to read and analyze specific papers, actively participate in discussions. Biology majors with junior and senior standing are required to successfully complete colloquim during all semesters on campus except for semesters when student teaching. The grade will be P/F. Non-credit course. One hour per week. Prerequisite: Biology majors with junior or senior class standing.
-
10.00 - 12.00 Credits
A work-oriented experience for junior or senior biology majors jointly sponsored by the Department and a public or private agency. The practicum is designed to integrate classroom theory with field or laboratory practice. In addition to attendance at a weekly seminar, students will spend 10-12 hours per week at the sponsoring agency. Academic work will include, but is not limited to: a log, readings, recitation and an assigned research paper related to the specific agency's activities. May be repeated once for credit with consesnt of instructor.
