Research overview: long-term study of the Serengeti lions

One of the longest-running studies of any wild big cat, the decades-long monitoring of lions in the Serengeti ecosystem has produced foundational knowledge of lion biology and conservation. This overview surveys the body of research built on following known individuals and prides across generations, illuminating pride structure, cooperative behavior, infanticide, reproduction, survival, and the drivers of population change. The long time series has revealed how disease epidemics, prey dynamics, and environmental variation shape lion numbers, and has tested ideas about social evolution and population regulation that would be impossible to study over shorter periods. Researchers have used the data to inform management questions from trophy hunting to disease. The overview frames long-term individual-based study as an irreplaceable resource for understanding lions, demonstrating how sustained monitoring of a single population over many years yields insights central both to behavioral ecology and to the conservation of the species.
