Do you want to develop the skills and knowledge needed to help preserve tropical coastal ecosystems? These habitats provide goods and services for hundreds of millions of people but human activities have led to their global decline. TROPIC101x will introduce you to the incredible plants and animals that create these unique ecosystems. You will go on to explore the challenges these ecosystems are facing such as overfishing, coastal pollution, ocean warming and acidification, then learn about some techniques being used to tackle these problems. Lectures will be delivered by leading experts. Many of them were filmed on-site in the Great Barrier Reef, at The University of Queensland’s research station on Heron Island. The course concludes with an innovative virtual ecology project, where you will have the option to take part in a citizen science project. Join us on an exciting journey, as you develop new knowledge and skills, during this beautiful and engaging course!

This course describes the large-scale circulation systems of the tropical atmosphere and analyses the dynamics of such systems. Topics include: Radiative-convective equilibrium; the Hadley and walker circulation; monsoons; tropical boundary layers; theory of the response of the tropical atmosphere to localized sea-surface temperature anomalies; intraseasonal oscillations; equatorial waves; El Niño/Southern Oscillation; easterly waves; and tropical cyclones.

This course provides students an understanding of important human parasitic diseases, including their life cycles, vectors of transmission, distribution and epidemiology, pathophysiology and clinical manifestations, treatment, and prevention and control.
