Management‐mediated predation rate in the caribou–moose–wolf system: spatial configuration of logging activities matters
Abstract Landscape complexity can determine the population dynamics of interacting predators and prey. Yet, management plans are commonly developed from aspatial predictive models. This oversight may result in unexpected outcomes or the loss of opportunities to make spatial interventions that would...
