This course is an upper division undergraduate class, and is also crosslisted as a graduate class (E251). This page contains information for both groups. Aspects that only apply to graduate students in this course are marked as such. Students are encouraged to contact me by email or see me for office hours if they have any questions or difficulties.
Population dynamics is the study of changes in population densities and the underlying biological forces which cause them; in other words the study of the factors that affect the growth, stability, and decline of populations, as well as the interactions of those factors. We will examine this on several levels: ecology (mainly compeition & predation), epidemiology of infectious diseases, the in vivo dynamics of viral infections, and the in vivo dynamics of somatic evolution and cancer. By nature, this is an interdisciplinary topic. It is very closely tied to the field of "theoretical biology", in which mathematical equations are used to analyse changes in population densities over time. The biological insights derived from such mathematical models form a central part fo the course. Undergaduate students are not expected to understand or perform details of the math. They are exected to understand the biological imporatance of the inights gained from theoretical work and answer questions accordingly. Graduate students who are taking the class are expected to follow the math.
