Effective population size ( N e ) is a key parameter for monitoring the genetic health of threatened populations because it reflects a population's evolutionary potential and risk of extinction due to genetic stochasticity. However, its application to wildlife monitoring has been limited because it is difficult to measure in natural populations. The isolated and well‐studied population of grizzly bears ( U rsus arctos ) in the...

Tanzania is a premier destination for trophy hunting of African lions (Panthera leo) and is home to the most extensive long‐term study of unhunted lions. Thus, it provides a unique opportunity to apply data from a long‐term field study to a conservation dilemma: How can a trophy‐hunted species whose reproductive success is closely tied to social stability be harvested sustainably? We used an individually based, spatially expli...
