Course handbook

Description

Introduces ecology focusing on population and community dynamics. Through case studies, the course examines the factors affecting the distribution and abundance of species (e.g. competition, predation). The basic models of population growth and how these are affected by the environment and complex behaviour patterns are covered. The course examines the question whether population numbers are regulated or merely responding to the environment. It discusses species diversity, introduced species and biological control, similarity among communities. Introduces the use of multivariate analysis methods for studying communities, and application of the island biogeography concept to designs of biological reserves. Australian case studies are used to illustrate concepts. Students will become familiar with the collection and handling of quantitative data and will develop appropriate scientific report writing skills. An understanding of the relationships between populations, communities and the environment is essential for anyone working in the environmental area.
