One way  to  understand how  early environment influences differing behaviours in  similar  species is  through the ? cross- fostering? Experimental technique. Suppose that the curly- whiskered mud rat differs from the bald mud rat in several ways, including being much more aggressive. How would you set up a cross- fostering experiment to determine if environment plays a role in the curly- whiskered mud rat's aggression?

#Unit 10. Ecological Principles
  1. You would cross curly- whiskered mud rats and bald mud rats and hand- rear the offspring.
  2. You would place new-born curly- whiskered mud rats with bald mud rat parents, place new-born bald mud rats with curly- whiskered mud rat parents, and let some mud rats of both species be raised by their own species. Then compare the outcomes.
  3. You would  remove the offspring of curly- whiskered mud rats and bald  mud rats from their parents and raise them in the same environment.
  4. You would see if curly- whiskered mud rats bred true for aggression.

Imagine that you are managing a large ranch. You know from historical accounts that wild sheep used to live there, but they have been extirpated. You decide to reintroduce them. After doing some research to determine what might be an appropriately sized founding population, you do so. You then watch the population increase for several gen- erations, and graph the number of individuals (vertical axis) against the number of generations (horizontal axis). The graph will appear as
