BIOL 333
Population and Community Ecology
Catalog Entry
BIOL 333
Population and Community Ecology
Three hours lecture; three hours laboratory(4).
Prerequisites: A grade of "C" or better in BIOL 131, BIOL 132, BIOL 231, and BIOL 232 and either STAT 219 or STAT 200 (STAT 219 or STAT 200 may be taken concurrently)
This course studies the distribution and abundance of species, and how populations
interact with each other and their environment. Investigations will encompass a broad
diversity of organisms from all parts of the world. Laboratory exercises will study
local species interactions, with a strong emphasis on field work.
Note(s): Scientific and Quantitative Reasoning designated course.

Detailed Description of Conduct of Course
Lecture time will depend on the approach of the instructor. In addition to, or instead
of, traditional lectures, instructors may opt to have class discussions of literature,
problem-based learning and team learning. Students will be asked to evaluate both
qualitative and quantitative evidence of case studies. During labs, students will
use observational and experimental approaches to investigate local ecological phenomena,
collect data, and will use computer software to analyze the resulting data sets.
Goals and Objectives of the Course
Having successfully completed this course, students will be able to do the following:
-explain what biotic and abiotic factors influence the distribution and abundance
of species
-understand, discuss and evaluate biological complexity
-learn and apply ecological models
-collect, analyze and evaluate qualitative and quantitative data
-design and carry out simple research projects
-explain the ways in which ecological systems are dynamic
-be more numerically and mathematically literate, with improved ability to use logarithms,
exponents, algebraic equations, and simple differential equations
-read and evaluate primary and secondary literature in ecology
Assessment Measures
Depending on the instructor, assessment strategies may include any or all of the following:
lecture exams, lecture quizzes, qualitative assessment of quality of research during
labs, lab quizzes, lab reports, reading and evaluation of primary and secondary literature,
papers on primary literature, papers derived from group discussions, qualitative assessment
of contributions to group discussions, and major projects.
