Problem:
In 1974, two hedgehogs were introduced into one of the islands in the Western Isles in Scotland, an area where hedgehogs do not naturally occur. Subsequent studies have shown that the hedgehog population doubled every year for the first seven years from two individuals in year 1 to 128 individuals in year 7.
Required:
Question1: How would you expect the rate of population growth to change in the future?
Question 2: Draw a graph to illustrate your prediction (no need to use graph paper), labelling axes and key features on the graph.
Question 3: What impact might this introduction have on the wildlife of the Outer Hebrides?
Please explain all the answers.
