Description This unit investigates how organisms respond to variation in climate and what can be done to reduce their vulnerability to anthropogenic climate change. The unit makes use of a novel conceptual framework that defines 'vulnerability' as a function of the 'exposure' and 'sensitivity' of organisms to climate change. Therefore, we will begin by exploring how organisms are exposed to climate change, from regional climatic changes acting at the scale of populations, to local climatological effects acting at the scale of individuals. Next, we will examine what determines the sensitivity of organisms, focusing on the physiological, behavioural, and life-history traits that affect the ability of organisms to cope with and adapt to climate change. Then, we will show how exposure and sensitivity combine to determine the vulnerability of organisms, including in both managed and natural ecosystems. Finally, we will discuss the 'mitigation' and 'adaptation' strategies that can prevent the worst of the potential impacts from becoming realised and help protect our biodiversity in the face of anthropogenic climate change.

Learning Outcomes

On successful completion of this subject, students should be able to:
  1. Describe how climate change will affect wildlife and ecosystems from local and global perspectives
  2. Explain the significance of historical changes in climate in shaping ecosystems and species radiations
  3. Evaluate climate change exposure at different temporal and spatial (global to microhabitat) scales
  4. Evaluate climate change sensitivity at all levels of biological organisation
  5. Analyse what drives vulnerability of organisms to climate change and what can help reduce impacts
  6. Conduct investigations safely and ethically in the field and laboratory, using sampling methodology correctly to obtain valid data
  7. Use spreadsheets and statistical tools in analytical programs to enter, analyse, and graph data; and use GIS and population modelling tools to draw appropriate conclusions from data
  8. Communicate findings correctly in oral or in written form using an appropriate style, as well as accessing the scientific literature to place the findings in context
