Questions 5 Time Limit 20 Minutes

There are 5 questions (multiple choice, matching and T/F) and you will have one attempt and 20 minutes to complete this quiz. Read Lab 2 (pp. 17-21) of your lab manual before taking this quiz. It is highly recommended that you complete the reading in its entirety before starting the quiz in order to finish on time. This is worth 10% of your lab grade, so please take this seriously. You must work alone, this is not a group project. Do not discuss the quiz questions with any students in later labs and until after everyone has taken the quiz. The quiz will open in a new window and has to be completed the first time it is launched. If you

Question 2

1 / 1 pts

When moose first arrived to Isle Royale in the early 1900s, there were no wolves or other predators just lots of grass, shrubs and trees to eat. They swam to this remote island 15 miles off the northern shore of Lake Superior near the Canadian border.

Correct!

True

Question 3

1 / 1 pts

When did the population ecology study of moose and wolves on Isle Royale begin? This is the longest running study of it's kind as ecologists are still studying these populations today. We have exciting updates to share with you in lab from February 2015.

Correct!

1958

Question 4

Match the population ecology term on the right with the definition of the term on the left.

Correct!

when it is cold enough that ice forms a bridge between mainland and an island.

Correct!

the maximum number of individuals of that species that the local environment can support at any particular time.

Correct!

The scientific study of changes in the size and composition of populations and the factors that cause those changes.

Correct!

how populations change through time

ou Answered

In this model, the per capita growth rate decreases as the population density increases and incorporates carrying capacity.

Question 5

2 / 2 pts

We will perform our own experiments during Lab 2 to study population dynamics using a computer simulation model based on a simplified version of the Isle Royale community. The underlying community includes five species: three plants (grasses, maple trees, and balsam fir trees), moose and wolves. Both the plant and animal communities are simplified. For example, both wolves and moose reproduce and the computer https:

simulation ignores gender in the model. There are many other simplifications and assumptions in this model to make this easy to study the population dynamics.
