Consider an ecosystem with rabbit and fox populations that follow Lotka-Volterra predator-prey dynamics. Identify all of the following three changes to the ecosystem that will NOT affect the long term equilibrium population of foxes, assuming no other changes to population sizes or growth parameters: 1) Removing half the rabbits and half the wolves from an ecosystem 2) Increasing the reproduction rate of the rabbits 3) Decreasing the life expectancy of the foxes
