BIO 270. Ecology and Evolution. An introduction to ecological and evolutionary
patterns, principles, and processes. Topics include life history
and adaptation, speciation, mechanisms of evolution, population
dynamics and interactions, community structure, and ecosystem
processes. Laboratories include experimental investigations of
several levels of biological organization using cooperative lab
groups. Prerequisite(s): Biology 101 or 190. S L Q W2 Normally
offered every year. Staff.

Course Philosophy
The lecture, lab, and field investigations
in Bio 270 expose students to three levels of biological organization:
the individual level (acid rain study), the population
level (White pine population study), and the community
level (rocky intertidal community study). Each study introduces
new levels of ecological complexity and avenues of inquiry to
stimulate critical thinking and to provide a frame of reference
for the lecture information. The studies have been designed to
incrementally introduce new concepts and techniques that build
on and reinforce information and skills learned in Bio 101 and
Bio 242. Ecology is a quantitative discipline, and thus we will
use a variety of quantitative tools to investigate and analyze
the problems posed.
As in the other biology core courses,
we place special emphasis on the processes of scientific inquiry
and communication. Effective communication in a scientific discipline
requires working knowledge of conventions of scientific writing
and the language used in the discipline. In addition to writing,
you will have opportunities to present information orally. Critical
thinking, analytical, and writing skills are best developed through
practice with challenging material; thus, lecture and lab provide
many opportunities to evaluate and interpret ecological data.
The instructional staff is there to assist and guide your learning
- use them and the other course resources to your best advantage.
