Wolves for Yellowstone: Dynamics in Time and Space

The reintroduction of gray wolves (Canis lupus) to Yellowstone National Park is the most celebrated ecological experiment in history. As predicted by population models, the rapid recovery of a wolf population caused both temporal and spatial variability in wolf–ungulate interactions … read more

Yellowstone Science – The Challenge of Understanding Northern Yellowstone Elk Dynamics after Wolf Reintroduction

The status and trend of the northern Yellowstone elk herd has been an enduring conservation issue throughout the history of Yellowstone National Park. It is the largest of about seven migratory elk herds that graze the park’s high-elevation meadows during … read more

Predicting Prey Population Dynamics From Kill Rate, Predation Rate And Predator–Prey Ratios In Three Wolf-ungulate Systems

Predation rate (PR) and kill rate are both fundamental statistics for understanding predation. However, relatively little is known about how these statistics relate to one another and how they relate to prey population dynamics. We assess these relationships across three … read more

Effects of Social Structure and Prey Dynamics on Extinction Risk in Gray Wolves

Extinction models based on diffusion theory generally fail to incorporate two important aspects of population biology—social structure and prey dynamics. We include these aspects in an individual‐based extinction model for small, isolated populations of the gray wolf (Canis lupus). Our … read more
