Short lecture by Prof Dr Bernd Blasius (University of Oldenburg)

The steady intensification of global shipping traffic is inadvertently leading to the spread of plants and animals between ecosystems around the world. These biological invaders can cause enormous ecological and economic damage and, in the long term, lead to the homogenisation of marine ecosystems by humans. The lecture shows how mathematical modelling can be used to quantify the complex network of international shipping and thus make the global spread of invasive species by modern shipping "calculable".
