1. Which of the following statements about Ecology is C
NOT true
a. Ecology is the study of how organisms interact
with their biotic and abiotic environment
b. Ecology is a large field that can be studied from
multiple perspectives, e.g., from an evolutionary
or behavioral perspective
c.The study of Ecology cannot occur at a global scale
d. Ecology is different than Natural History in that
Ecology is hypothesis driven
e. All of the above are true

2. At which hierarchical level of ecological study would D
the following question be asked: How do nutrients
flow between freshwater and saltwater ecosystems?
a. Ecosystem
b. Population
c. Community
d. Landscape
e. None of the above

3. White-throated Sparrows are a species of songbird.

B Individual White-throated Sparrows have either
white or tan throats. It is known that throat color in this
species has a genetic basis. If we were to ask how
the ratio of white alleles to tan alleles changed over
times in a mountain population of the White-throated
Sparrows, at which hierarchical level of Ecology is the
question being asked?
a. Community
b. Population
c. Individual
d. Ecosystem
e. Landscape

4. Which of the following does NOT make a good ecolog- B
ical question:
a. It is relevant to the party of interest
b. It can be resolved with subjective data

c. It must be testable
d. It must be novel to the system you are studying
e. It can test a known theory

5. Hurricanes on the East cost of the United States have
A become more destructive over the past 30 years. We
propose that climate change is impacting hurricane
severity, and as such, we expect to find a positive cor-
relation between sea surface temperature and flood-
ing during hurricanes.

The underlined portion of the statement above is the
a. hypothesis
b. prediction

6. Hurricanes on the East cost of the United States have
B become more destructive over the past 30 years. We
propose that climate change is impacting hurricane
severity, and as such, we expect to find a positive cor-
relation between sea surface temperature and flood-
ing during hurricanes.

The bold portion above is the:
a. Hypothesis
b. Prediction

7. Hurricanes on the East cost of the United States have
B become more destructive over the past 30 years. We
propose that climate change is impacting hurricane
severity, and as such, we expect to find a positive cor-
relation between sea surface temperature and flood-
ing during hurricanes.

Imagine that the study above was conducted, and a
positive correlation between sea surface temperature
and flooding was identified, but the relationship was
found not to be statistically significant. In this case,
which of the following would be true?
a. The research hypothesis would be supported

be supported

would be supported

D toperiod (daylength) trigger Magnolia warblers to be-
gin their fall migration? Which type of mechanism(s)
are we studying to explain this phenomenon (of Mag-
nolia warblers migrating in the fall)?
a. An evolutionary mechanism
b. An ultimate mechanism
c. A fitness mechanism
d. A proximate mechanism
e. Both b&d

9. If we were to ask the following question: Does individ-
D ual variation in territorial aggression lead to
variation in reproductive success in song sparrows?
Which
type of mechanism(s) are we studying to explain
this phenomenon (individual variation in territorial ag-
gression)?
a. A physiological mechanism
b. A proximate mechanism
c. A fitness mechanism
d. An ultimate mechanism
e. Both b&d

10. If we were to ask the following question: Why do

D animals prefer fatty food? Which type of mechanism
are we studying to explain this phenomenon (animals
prefer fatty food)?
a. Proximate
b. Fitness
c. Ultimate
d.We can explain this phenomenon with either a
