PLANT SC 7022EX - Invasion Biology: Foundations of Biosecurity

External - Semester 2 - 2014

An understanding of invasion biology provides a foundation for the principles and practices of biosecurity. This course will consider case studies of insects, plant diseases and weeds that have invaded ecosystems. This will lead to a consideration of the ecological theory that aplies to biological invasions, including colonisation and propagule pressure, population growth, predator-prey and pathogen host interactions, Allee effects and population viability, the factors that affect the spread of invasive species, and the genetics and evolution of founding populations. The biological and ecological factors that influence the impact of invasive species will be evaluated.
