BIOL 399: Form and Function in Organismal Biology
Instructor: Iriarte Diaz
Credit hours: 4
Course Description:
This seminar explores the relationships between an organism's anatomical structures and its ecology and behavior. For instance, how do bird wings enable flight? Can we predict variations in bird flight habits based on wing shape or feather structure? We will start by discussing animal body size and metabolism, then move on to various forms of locomotion. After that, we will explore morphological adaptations related to prey capture, predator avoidance, and reproduction. Lastly, we will examine how animal morphology inspires human innovation. Lectures include discussions of the scientific literature.
BIOL 399: Ichthyology (lab)
Instructor: Wells
Credit hours: 4
Course Description:
The course introduces students to current topics of importance to the study of fishes. An emphasis will be placed on the fishes of Tennessee and the Southeast. Topics to be covered: evolutionary history, structure and form, taxonomic diversity, ecology and conservation, research techniques, and standard sampling and identification methods.
BIOL 399: Stem Cells
Instructor: Rodriguez
Credit hours: 4
Course Description:
This course will explore the biological principles, technological advancements, and ethical dilemmas surrounding stem cell research and biotechnology. Students will first develop a foundational understanding of stem cell biology, including the regulation of stem cells and the development of induced pluripotent stem cells (iPSCs). The historical trajectory of cloning will be examined alongside the scientific breakthroughs and societal responses that have shaped public perception and policy. The course will also focus on ethical inquiry, inviting students to critically analyze how we have addressed fundamental questions about the sanctity of life, the definition of personhood, and the moral boundaries of scientific exploration. Through discussions, case studies, and literature reviews, students will engage with bioethical frameworks and debates about biotechnology’s potential to transform the future of medicine.
BIOL 399: Tropical Biology: Field Studies in Ecuador (lab)
Instructor: McGrath
Credit hours: 4
Course Description:
This course explores the rich diversity and ecological complexity of Ecuador’s tropical ecosystems with an emphasis on applying ecological principles to real-world conservation challenges. Students will study Amazonian rainforest, Andean cloud forest and pampas, coastal mangroves and marine ecosystems. Topics include species adaptations and interactions, conservation biology, climate change impacts, and sustainable resource management. During a four-week immersive field trip to the Galapagos Islands and Ecuadorian Amazon, students will engage in hands-on research and learn from local scientists and communities. The course is only open to students enrolled in the Ecuador Global Environmental Challenges study abroad program.
