If the wolf population goes extinct on the island, what is likely outcome

The moose population will grow and eat all the vegetation

Moose will die due to lack of predators

The other species that rely on the vegetation will take over for the wolves

New predators will begin hunting Moose

If wolves were re-introduced what would happen to the moose population

The moose population would decline to normal levels

The moose would go extinct from over hunting

The wolf population would take over the island

The moose would adapt to other environments

Which of the following factors affect a population's size

All of the choices affect population

We know that population sizes change over time. All statement(s) are true about this change EXCEPT:

When there are more deaths than births the population size will increase.

When there are more births than deaths the population size will increase.

When there are more deaths than births the population size will decrease.

When there are more births than deaths the population size will increase

Birth rates in a population, such as the moose on Isle Royale, can be affected by all of the following EXCEPT:

No exceptions - All of these factors affect birth rates.

Present day extinctions are happening at the greatest rate on islands. All of the following statements are reasons for this EXCEPT:

islands are isolated from humans

invasive species have been brought to islands by humans

Islands have smaller population sizes so they are more impacted by changes.

There is less space on islands so species have to compete more with each other.

No exceptions - all statements are true.

Review the graph provided. What statements can be made about the significant decline in wolves around 1979?

The drop is most likely due to the declining moose population, but more information would be needed to determine that.

The wolf decline was a direct result of moose decline.

The is no way to know why the wolf population dropped.

The drop is most likely due to the increasing moose population, but more information would be needed to determine that.

The wolf decline was a direct result of the moose increase.

Review the graph provided. What statements can be made about the significant decline in moose in the mid 1990's?

The drop is most likely due to the increasing wolf population, but more information would be needed to determine that.

The moose decline was a direct result of wolf decline.

The is no way to know why the moose population dropped.

The drop is most likely due to the declining wolf population, but more information would be needed to determine that.

Humans are causing extiction in which ways?

By poaching animals for food or products.

By destroying the natural habitat of species.

By polluting the environments of the world.

What was the solution suggested by the research scientists to the wolf population problem?

Bring in another pack of wolves

Remove the last two so the moose could thrive.
