Ethan J. Temeles (Section 01)


(Offered as Biology 23 and Environmental Studies 21.) A study of the relationships of plants and animals (including humans) to each other and to their environment. We'll start by considering the decisions an individual makes in its daily life concerning its use of resources, such as what to eat and where to live, and whether to defend such resources. We'll then move on to populations of individuals, and investigate species population growth, limits to population growth, and why some species are so successful as to become pests whereas others are on the road to extinction. The next level will address communities, and how interactions among populations, such as competition, predation, parasitism, and mutualism, affect the organization and diversity of species within communities. The final stage of the course will focus on ecosytems, and the effects of humans and other organisms on population, community, and global stability. Three hours of lecture per week.

Requisite: Biology 18 or Environmental Studies 12 or permission from the instructor. Not open to first-year students. Fall semester. Professor Temeles.
