Seasons of Change Activity Worksheet—Disappearing Marine Iguanas Case Study
Instructions: Complete the lab report below while you explore the impact the events have on the Marine Iguana population in the Seasons of Change Activity—Disappearing Marine Iguanas Case Study. You will submit your completed activity worksheet.

(20 points possible)

Part One

Using the map and the minimal knowledge that Liz has at this point, propose three different hypotheses regarding the sudden high mortality of marine iguanas. Post your hypotheses to the discussion board before proceeding to the next question. (3 points possible)
Hypotheses One:

Hypotheses Two:

Hypotheses Three:

Look at your classmates’ hypotheses on the discussion board. Choose one hypothesis that seems most likely to you. Provide the student name and hypothesis and tell what evidence you would need to support (or refute) it.(3 points possible)

Part Two

Given what you know at this point about marine iguanas and the abiotic effects of ENSO, develop two possible directions of research that Liz should pursue to understand exactly why the iguanas suffered such a high mortality. Keep in mind that you need to consider indirect effects. While environmental temperature does change metabolic rates of ectotherms, the iguanas are exposed to a wide range of temperatures as they feed and bask on the lava. Direct mortality in response to a temperature change of a couple of degrees is unlikely. (3 points possible)
Possible Research Direction One:

Possible Research Direction Two:

Choose one of those directions of research and determine what data you would need to find to support your ideas. (2 points possible)
Design an experiment that would help you collect the data you have identified in question four. Identify your independent variable(s), dependent variable(s), treatments, and control. (5 points possible)
What conclusions do you think Liz made about the cause of population declines in marine iguanas? (4 points possible)

1. Using the map and the minimal knowledge that Liz has at this point, propose three different hypotheses regarding the sudden high mortality of marine iguanas. Record your answers in the worksheet and post your hypotheses to the 03.01 class discussion board before proceeding to the next question. (3 points possible)

Hypotheses One: Iguanas are adapted to hot/warm weather, so the weather changed could have affected them.

Hypotheses Two: There was not enough shelter for the iguanas so they started disappearing.

Hypotheses Three: A new species has come close to where the iguanas live and taken them out.

2. Look at your classmates’ hypotheses on the discussion board. Choose one hypothesis that seems most likely to you. Provide the student name and hypothesis and tell what evidence you would need to support (or refute) it. (3 points possible) Carter Spiers, Hypothesis 1. there was a lot of rain and it washed at the iguanas away. We would have to dive into the water/ ocean and find iguana bodies to be able to prove that this is true.

3. Given what you know at this point about marine iguanas and the abiotic effects of ENSO, develop two possible directions of research that Liz should pursue to understand exactly why the iguanas suffered such a high mortality. Keep in mind that you need to consider indirect effects. While environmental temperature does change metabolic rates of ectotherms, the iguanas are exposed to a wide range of temperatures as they feed and bask on the lava. Direct mortality in response to a temperature change of a couple of degrees is unlikely. (3 points possible)

Possible Research Direction One: The climate event caused a lot more rainfall which then made it very hard for the iguanas to reach their food source.

Possible Research Direction Two: The temperatures raised very high causing the iguanas to absorb a extreme about of extra heat, which eventually made them very lazy and stopped defending their self from predators.

4. Choose one of those directions of research and determine what data you would need to find to support your ideas. (2 points possible) Specific data of the extreme amounts of rainfall.

Using the map and the minimum information that Liz has at this point, advise 3 exclusive hypotheses concerning the surprising excessive mortality of marine iguanas, subsequent question. (three factors possible).

Hypotheses One: Iguanas are tailored to hot/heat climate, so the climate modified may want to have affected them.
Hypotheses Two: There become now no longer sufficient safe haven for the iguanas so they began out disappearing.
Hypotheses Three: A new species has come near in which the iguanas stay and brought them out.

2. Look at your classmates' hypotheses at the dialogue board. Choose one speculation that appears maximum probable to you. Hypothesis 1. there has been of rain and it washed on the iguanas away. We might should dive into the water/ ocean and locate iguana our bodies on the way to show that that is true.

3. Given what you already know at this factor approximately marine iguanas and the abiotic consequences of ENSO, expand feasible instructions of studies that Liz ought to pursue to apprehend precisely why the iguanas suffered the sort of excessive mortality.

Possible Research Direction One: The weather occasion brought about plenty extra rainfall.
Possible Research Direction Two: The temperatures raised very excessive inflicting the iguanas to soak up.

4. Choose one of these instructions of studies and decide what records you'll want to locate to help your ideas. (2 factors possible) Specific records of the intense quantities of rainfall.

What is Marine Iguanas Case Study?

Marine iguanas are maximum mentioned for cappotential to feed in shallow, marine waters. They are herbivores and devour marine algae developing alongside rocky sea shore lines and underwater.
