Question 1

Which of the following best explains why the Sonoran Desert is located where it is in North America?

Accepted Answer

It is located in a rain shadow created by nearby mountain ranges, which block moist air and cause dry conditions.

Question 2

What is the primary reason for the seasonality experienced on Earth?

Accepted Answer

The tilt of the Earth's axis at $$23.5^{\circ}$$ relative to its orbital plane.

Question 3

At which latitude would you expect to find the highest average annual precipitation due to global circulation patterns?

Accepted Answer

$$0^{\circ} ($$the equator)

Question 4

Why is the climate of Seattle, WA, milder and wetter than Portland, ME, even though they are at similar latitudes?

Accepted Answer

Seattle is influenced by warm ocean currents from the Pacific, while Portland, ME, is influenced by cold currents from the Atlantic.

Question 5

Which of the following is NOT typically included in species distribution modeling (SDM) for predicting the future range of a species?

Accepted Answer

The presence of specific seed dispersers or competitors.

Question 6

If the Earth's axis were tilted at $$0^{\circ}$$ instead of $$23.5^{\circ}$$, what would be the most likely effect on global climate?

Accepted Answer

There would be no significant seasonal variation in temperature.

Question 7

Which of the following best describes the effect of warm ocean currents on the climate of coastal regions?

Accepted Answer

They make the climate warmer than expected for that latitude.

Question 8

A researcher is using ecological niche modeling (ENM) to predict the future distribution of a plant species. Which of the following variables would most likely be included in the model?

Accepted Answer

Annual range of temperature and precipitation in the wettest month.

Question 9

Which of the following statements about the Hadley cell is correct?

Accepted Answer

It is responsible for high rainfall at the equator and dry conditions at $$30^{\circ}$$ latitude.

Question 10

A rain shadow is most likely to occur on which side of a mountain range?

Accepted Answer

The leeward side, where descending air is dry.

Question 11

If climate change causes the annual mean temperature in a region to increase by $$2^{\circ}C$, what is a likely effect on the distribution of a tropical plant species?

Accepted Answer

The suitable range for the plant may shift to higher latitudes or elevations.

Question 12

Which of the following is a limitation of using only abiotic factors in species distribution models?

Accepted Answer

They do not account for biotic interactions such as competition or mutualism.

Question 13

Based on the study design for predicting açaí palm distribution, which of the following steps is essential for making future predictions?

Accepted Answer

Obtain climate change predictions for the target year (e.g., 2080).

Question 14

Which of the following best describes the conclusion of the açaí palm distribution study?

Accepted Answer

The suitable area for açaí palm growth will change, increasing in some areas and decreasing in others, but not all factors are included in the model.

Question 15

Which of the following is a correct prediction of the null hypothesis in the açaí palm study?

Accepted Answer

The areas of suitable growth for açaí palms will be the same in 2080 as they are now.

Question 16

Which of the following is a real-world application of GIS and spatial analysis in biology?

Accepted Answer

Predicting the future distribution of species under climate change scenarios.

Question 17

If a region is located at $$30^{\circ}$$ latitude and is far from any ocean, what climate characteristics would you expect?

Accepted Answer

Dry conditions with low annual precipitation.

Question 18

Which of the following best explains why Great Britain has a milder climate than Newfoundland, even though they are at similar latitudes?

Accepted Answer

Warm ocean currents from the Gulf Stream warm Great Britain, while Newfoundland is bypassed by these currents.
