BZ3235 - Biological Invasions

Subject Description

Invasive species pose a significant threat to the maintenance of ecosystem services and the conservation of native species. Australian local, state, and federal governments collectively spend billions of dollars annually to prevent the establishment of new invaders and mitigate damage from those that have established. This subject provides an overview of the biology and ecology of invasive species, with a focus on plant, animal, and microbial invaders in tropical ecosystems. The subject will cover characteristics of invasive species and processes involved in their introduction, establishment, and spread. The subject will also emphasize ecological effects of invaders and the challenges of invasive species management and control with historical and contemporary examples.

Learning Outcomes

• critically assess scientific literature
• demonstrate understanding of the process of biological invasions and factors affecting the process at each stage
• demonstrate understanding of the diversity of life histories, habitats, and biology among plants and animals and how they influence species invasions
• summarize the scientific and practical considerations necessary in the design of management programs for invasive species
