Moose and Wolf Population Dynamics

The video tutorial discusses a graph showing the populations of wolves and moose on Isle Royale over 40 years. It explains the graph's layout and provides background on Isle Royale's wildlife. The tutorial then explores limiting factors for the moose population, such as food availability, and explains the rapid increase in the wolf population between 1975 and 1980, attributing it to the abundance of moose as a food source.
