Biological invasions are widely recognized as one of the main drivers of the drastic biodiversity loss that characterizes the Sixth mass extinction, one led by anthropogenic factors. In this course, we will explore how biological invasions come to be, how they affect the native ecosystem, and how they can be prevented, controlled, and managed. We will study the traits that make invasive populations so successful and how evolutionary change shapes these traits through time. Biological invasions don’t occur in isolation, so we’ll examine their interaction with other global change factors such as urbanization, globalization of trade, and climate change. In addition, we will examine how the narrative around biological invasion has been often shaped by xenophobic and racist ideologies, often generating vitriolic language and attitudes, even towards harmless non-native species. While treating a variety of topics, we will examine the theoretical background, consider specific case studies, and develop a deeper understanding through class discussions, readings, and assignments. Welcome to Biological Invasions!
