5 Questions
What is the relationship between population size and competition among moose?
In a smaller population, there would have been less competition.
Why is it sometimes difficult to determine if a limiting factor acts only in a density-independent way?
Because in certain situations, competition can still be a factor even at low population densities.
What are the implications of artificial density-independent control measures like hunting?
They are expensive and offer little hope of success.
What happened when European rabbits were introduced to Australia?
They multiplied rapidly and grew into a population estimated at 600 million individuals.
What impact did the rapidly multiplying rabbit population have on the Australian landscape?
The rabbit population threatened native plants and herbivores with extinction.
