Brainstorm. List the factors that you think lead to a loss of diversity. Do you think the loss of diversity is the same from country to country? Why / why not?. Learning outcomes. You will all be able to: Identify the factors that lead to a loss of diversity Most of you should be able to:
Loss of tropical rainforest
North Atlantic Bluefin tuna
Introducing non-native species
Black rat (Rattusrattus)
What is it that makes them so diverse in terms of species?
They contain a lot of long-lived species and it has taken thousands of years for them to develop. If they are damaged it will take a long time for them to regenerate. Why?
Read the facts from the National Geographic article “Rain Forest Threats” and relate this to what we have been looking at on the loss and retention of diversity.
Using this, write down the factors that make rainforests vulnerable to disappearance.
