Shaped by millions of years of evolution, animals have evolved myriad abilities to respond to their environment, their potential predators and prey, and members of their own species. This course examines animal behavior from both a mechanistic and a functional perspective. Drawing upon examples from a diverse range of taxa, and using articles from the primary scientific literature, we will discuss topics such as behavioral endocrinology, sexual selection and mating systems, animal communication, and kinship and cooperation. Three classroom hours per week.

(Offered as BIOL 230 and ENST 210) 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.

How can a single cell, the fertilized egg, give rise to all the specialized cells of an adult? What gives rise to biological form? What is the molecular logic of the pathways that progressively refine cellular identities? How do cells "talk" to one another so as to coordinate their behaviors as embryos develop form and function? How can parts of an organism be regenerated with only the appropriate regions remade, structured identically to the missing ones? How does a stem cell differ from a non-stem cell? How can genetically identical organisms be cloned?

Advances in organismal biology hinge upon an understanding of natural history and are enhanced by quantitative observation, hypothesis formation, and experimentation with systems that occur in nature. In this course, we will apply these principles specifically to the study of infectious diseases in natural populations. With a combination of lecture, discussion, and field-based activities, the course will focus on deriving important questions and the variety of approaches to address them.

An introduction to the molecular and cellular processes common to life with an emphasis on control of energy and information flow. Central themes include metabolism, macromolecular function, and the genetic basis of cellular function. We examine how membranes work to establish the internal composition of cells; how the structure of proteins including enzymes affects protein function; how energy is captured, stored and utilized by cells; and how cells communicate, move and divide.
