BIOL 131-01 Introduction to Organisms, Populations, and Ecosystems: The Physiology of Life
Instructor: Scott Boback
Course Description:
This introductory course spans levels of biological organization from basic multicellular microanatomy to organismal physiology and ecology, as understood through the lens of evolution. Course content will be focused around a specific theme determined by the instructor, and will include evolutionary principles of variation, selection, competition and cooperation, and how their operation at different levels of organization accounts for form and function of organisms, communities, and ecosystems. We will investigate homeostasis, reproduction and development as physiological processes that take place within organisms, and as ecological processes that interact with the environment and generate diversity of form over evolutionary time. Finally we will take stock of the existing forms and levels of biological organization and ask how their relationships establish the biosphere in which we live. Three hours classroom and three hours laboratory a week. This is one of two courses required of all Biology majors before entering the upper level. It is complementary to BIOL 132 Introduction to Molecules, Genes, and Cells, and the courses may be taken in either order.

BIOL 301-01 Wildlife Ecology
Instructor: Gene Wingert
Course Description:
Wildlife Ecology is designed for majors in both Environmental Science and Biology. This course approaches ecology from the aspect of focusing on individual organisms and the role they play in their environment. Students will visit various habitats in Pennsylvania and view wildlife first hand. The texts are both place based focusing on Northeastern forests and Northeastern vernal ponds. These two ecosystems are intimately linked and the health of one influences the other. Students will have hands on labs with living organisms and investigate the roles each of these organisms play in the forest and vernal pool environment. A focus of the course will be how we must manage these ecosystems if they are to be enjoyed by our grandchildren. Both of these ecosystems are being changed by human ignorance and global climate change. We are at a squeak point in our ability to sustain these ecosystems. Only a complete understanding of their ecology and rapid action will sustain them for future generations.

BIOL 412-01 Precision Medicine
Instructor: Michael Roberts
Course Description:
According to the National Institutes of Health (NIH), precision medicine is "an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person." This departure from the "one-size-fits-all" approach to patient care has been made possible by advances in molecular medicine that have created an "-omics" era of large-scale data-rich biology. We will explore these new -omics methods and their applications in preventing, diagnosing, and treating human disease. As precision medicine is being implemented, there is also a call for the transformation of medicine from "sickcare" to "wellcare" where medical care is not only personalized but patient participatory, predictive, and preventative. The course will explore the primary literature to discover the most recent advances in precision medicine and discuss the social implications of a new era of scientific wellness. This course will fulfill the Biology major research requirement.
