Biological time-keeping in an urbanising world: The role of artificial light at night

Venue: D502

Abstract
The worldwide increase in urbanisation poses challenges for wildlife. While several species failed to colonise cities, others do manage to establish and thrive in urban areas, and show impressive phenotypic changes. In particular, urban animals have been repeatedly shown to shift their temporal activity strategies, both on a daily and seasonal basis. My research tries to answer three main questions: 1. How do these alternative temporal tactics come about? 2. What are the physiological mechanisms that underlie them? 3. What are their fitness consequences? To answer these questions I integrate research at several levels of biological organisation using a wide array of techniques and approaches, from gene expression analysis to biotelemetry, and through both laboratory and field experiments. During my seminar I will report on several studies that I have conducted in recent years that aimed at answering these three main questions. A major focus of the talk will be on the role that artificial light at night plays in defining the biological time-keeping of urban animals, and its interaction with other anthropogenic pressures.
