Wolves recolonized a large area around Grand Teton National Park (GTNP) in the late 1990’s. Wolf biologists started estimating the number of wolves in 2000 at 21 wolves in GTNP population. The population growth rate of wolves is 8.4 per year. What will the population size be in 2023? 2030? What does this assume about population growth? State biologists want to know how long it will take for this population to reach 175 wolves so they can delist them in this region of Wyoming.

R and K Selection

R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.
