Use the graph to help you answer the questions that follow. 1. Calculate the average increase in southern sea otter population size. If this population continued to grow
at a constant rate, when should it have reached the delisting threshold of 3,090 animals?
2. Are otter reproductive patterns more like r-selected species or K-selected species? What are the
implications of this reproductive pattern?
3. What shape would you expect the otter's survivorship curve to take? Consider their high juvenile
mortality rate.
4. Design an experiment to test a hypothesis about the effect of one of the factors described on sea otter
population size.
