Module content and teaching
Non-native invasive species pose significant threats to natural and agricultural ecosystems worldwide and often have very severe, though difficult to quantify, economic impacts. Invasive species rank second only to habitat loss and destruction in a list of global threats to biodiversity. Climate change and environmental degradation, together with increased global trade, increase opportunities for the introduction, spread and persistence of invasive species and hence there may undesirable interactions between biological invasion and climate change. This module will introduce students to the basic principles of invasion ecology. These principles will be illustrated with a number of case studies which will examine in more detail examples of invasive plants, pathogens, microbes and insects in agricultural and natural terrestrial, aquatic and marine environments. These more detailed studies will investigate the economic and environmental impacts of invasive species and will also consider potential impacts on human health. Throughout, the current and future impacts of environmental change on invasive species will be considered. This module will enable students to evaluate the threats posed by invasive species in agricultural and natural ecosystems that are subject to increased environmental change and disturbance.
Principal learning outcomes
By the end of the module the student should be able to: Understand the biological characteristics of invasive species and the ecological principles that underpin the invasion process; Evaluate critically the agricultural, environmental, economic and human health impacts of invasive species; Ability to test and evaluate avoidance and management strategies for invasive species; Show critical awareness of the potential impacts of climate and environmental change on biological invasions.
