WILDLIFE POPULATION MODELING (WIS 6466)
[ Back To Courses ]
COURSE DESCRIPTION:
Matrix population models are standard tools for the study of life history and population dynamics of age- or stage-structured populations. These models have become popular in population biology because they can be applied to organisms with diverse life-histories and population structures. This course is designed to provide a rigorous background in theory of matrix population models, and application of these tools to address basic and applied ecological questions. Relevant concepts in matrix algebra will be reviewed to provide necessary mathematical background. Computer exercises will involve analysis of real-life data using MATLAB.
COURSE OBJECTIVES:
By the end of the semester, students will:
- have a thorough understanding of the process of modeling the dynamics and persistence of biological populations
- be able to construct and analyze life tables, and age- and stage- structured matrix population models,
- be able to conduct prospective and retrospective perturbation analyses and population viability analysis, and
- be able to apply matrix population models to address basic and applied ecological questions using MATLAB and other software packages.
