Based on our recent lecture discussion of values, is the following statement TRUE or
FALSE?
If a person believes that a particular species has an intrinsic right to exist just because it
exists, then that person clearly assigns ecological value to the species. - correct
answerfalse
The 'Chasing Rainbows' article suggested that the mountain yellow-legged frog
populations in Yosemite National Park were most likely declining due to
________________________.
Read the options carefully, then choose the best answer. - correct answera successful
introduced predator
Logistic growth is graphically represented by ______________________. - correct
answeran S-curve
True or False?
In 'Chasing Rainbows', you read about the exhaustive efforts of the U.S. Forest Service,
California Fish and Game, and local citizens to restore the native rainbow trout
populations that were eradicated from some mountain lakes because they were
outcompeted by an exotic species. - correct answerfalse
Natural populations are dynamic---they increase, decrease, and otherwise respond to
changes in their biotic and abiotic environment.
Which of the following is most critical for distinguishing between natural population
fluctuations and the population declines that some species are experiencing in the world
today? - correct answera long-term study of population data
Which of the following ARE examples of a population. - correct answerall of the people
in New Zealand; all of the cornflowers in France; all of the spotted salamanders in New
Hampshire
In lecture, we discussed the difference between 'species richness' and 'species
evenness.' Based on our discussion in lecture, is the following statement TRUE or
FALSE?
,Species richness is a particularly descriptive measure of community composition (and
the diversity of species in a given area) -- it tells us not only the number of distinct
species in the community, but also their relative abundance. - correct answerfalse
In our recent lecture on Population Ecology, we discussed the 4 phases of logistic
growth (the S-shaped growth curve). I explained that the third phase of a logistic growth
curve, called the ________________, occurs as the population is approaching
_______________.
Select the appropriate pair of answers to best complete the sentence above. - correct
answerdeceleration phase; carrying capacity
Recall the story from our recent lecture about the recovery of a snake that was listed as
Federally Threatened. Is the following statement TRUE or FALSE?
The Lake Erie Water Snake and the Round Goby are both endemic to the islands in the
Western basin of Lake Erie. - correct answerfalse
If two species occupy the same __________________ in a community, then according
to the competitive exclusion principle, the species that more efficiently exploits the
shared resource(s) (in other words, the better competitor) will eventually exclude the
other species from the community.
Select the best option (from the list below) to fill in the blank. - correct answerniche
When we moved into our house (5 years ago), we inventoried the pond on our property
to understand which species belonged to our backyard amphibian community.
After 5 years, we re-inventoried our backyard pond to see what our current backyard
amphibian community is like.
In 2012, there were 3 frog species and 2 salamander species in the backyard
amphibian community.
Last summer, in 2017, there were 4 frog species and 1 salamander species in the
backyard amphibian community.
The change we observed in the composition of our backyard amphibian community is
best described as _______________________. - correct answerspecies turnover
True or False?: Both species in a symbiotic relationship must benefit in some way from
the interaction. - correct answerfalse
Recall the 'Chasing Rainbows' article that you read for Module 1 (and reviewed for
Module 2). Which of the following terms describes the mountain yellow-legged frog in
California and Nevada?
Select the best answer from the options below. - correct answerheterotroph
, True or False?: Biogeochemical cycles are the pathways by which chemical elements
move through the biotic and abiotic components of the Earth ecosystem. - correct
answertrue
Which of the 'CHNOPS' elements makes up > 70% of the atmosphere (the air we
breathe)? - correct answernitrogen
In a recent lecture, we talked about the environmental criteria that determine whether a
species might exist in a given region/habitat.
Recall that an organism's survival depends on many essential factors in its physical
environment and that, for each factor, we can describe the species' range of tolerance.
Which of the following fall within a species' range of tolerance for a given environmental
factor?
Select any and all that apply. - correct answerzone of physiological stress; range of
optimum (=optimal range)
One way in which humans impact wild populations (of non-human species) is by
isolating once large or contiguous populations into much smaller groups.
Which of the following phenomena are likely to result from this sort of isolation?
Based on your reading of the Module 3 materials, select any and all appropriate
answers from the following list. - correct answerfounder effect; genetic drift; speciation
events
True or False? ::: A population bottleneck (the nonrandom change in the gene
frequencies of a population) is a perfect example of natural selection. - correct
answerfalse
True or False? ::: Individuals evolve in response to changes in the environment. -
correct answerfalse
Recall our earlier discussions about biodiversity...
Approximately how many distinct species have been identified to date? - correct
answer~ 2 million
Pure chance (random mating) can result in an increase or decrease in the frequency of
a particular trait in a population -- this process is known as "_____________________."
Select the best answer from the options below. - correct answergenetic drift
