This module provides a foundation in the ecological theory of colonization and invasion and focuses on the introduction and characteristics of plants and animals and their environmental and economic implications. The content focuses on the global threat of invasive species and the issues around managing the risk in a sustainable way. Concepts and issues explored include patterns of introduction, ecological disturbance and succession, herbivory/predation and the role of competition, risk assessment, practical management, biological control, cost and benefits of control in a global context. The content is illustrated with case studies from terrestrial, freshwater and marine habitats. A small case study on a species or system of choice will provide relevant local information and assignments will provide information on key concepts through active learning.
