Abstract
Ecology is the science of the interactions between living organisms and their environment; this environment itself consists of other living organisms, which in turn interact with their own environment and with other living organisms. It is clear from the very definition of ecology that this is a discipline which deals with complex phenomena. And it is certainly this complexity – both fascinating and challenging – that constitutes one of the most interesting aspects of studying ecology. Even when systems appear simple, or interactions seem logical, this often subtle complexity reveals paradoxes that are as surprising as they are delightful. More often than not, these paradoxes are merely apparent, arising from our partial view of the systems under study. Ultimately, several decades of research have taught us that the only way to understand biodiversity – and the ecology that studies it – is through a comprehensive, holistic approach. Drawing on examples from the work that has marked my career as an ecological researcher, this opening lecture will move from paradox to paradox, demonstrating how complexity in ecology necessitates a holistic approach. From cats hunting rats and birds to lions hunted for their trophies, from ant battles to fighting beetles, from protective fires to species that are both threatened and threatening, we shall explore together some examples of the questions, systems and studies that form part of my daily life as an ecologist.
