Scaling from nano to global impacts: mechanisms of tree mortality

Featured Scientist: Professor Brendan Choat, Hawkesbury Institute for the Environment

Brendan Choat is a world leader in plant water relations and interested in how plants, especially trees, cope with water stress. Brendan works on plants from the nanometer to continental scales, piecing together how native and also crop species cope with environmental stresses like drought and fire. Brendan explains in a great and easy to understand way how climate change is impacting our forested landscapes in Australia and how his work is helping conservation management. He also explains what cavitation is and how it leads to ‘popping’ sounds in trees.
