BIO 322 Exam 2 Chapters 6-11 Questions With Complete
Solutions
A large value of FST (the inbreeding coefficient) relative to FST
values calculated for similar types of species indicates that
A. the populations under examination are well connected by
migration.
B. a dispersal corridor may be a good investment because
migration between sub-populations is currently limited.
C. out breeding depression is likely occurring.
D. this species is unlikely to use a dispersal corridor, so there is
no point in creating one. Correct Answers B. a dispersal
corridor may be a good investment because migration between
sub populations is currently limited.
A population of biennial plants (composed of seeds, one-year-
old plants, and two-year-old plants) is affected by a fungal
disease that causes mortality of some one-year-old plants. If the
demographic matrix for this population is,
**Figure in chapter 9 Quiz Q4**
what value would you change to assess how much conservation
benefit could be gained by applying a fungicide to the plants?
A. 0.7
B. 0.2
,C. 0.6
D. 10 Correct Answers C. 0.6
** This is the probability that a one-year-old plant survives to
become a two-year-old plant. And since the fungal disease
causes mortality of one-year-old plants, this is the value you
would want to change to assess the potential conservation
benefits of spraying a fungicide to control the pathogen.**
A population of biennial plants (composed of seeds, one-year-
old plants, and two-year-old plants) is affected by deer that
graze off some of the flowering stems and thereby reduce the
average number of seeds produced per plant. If the demographic
matrix for this population is,
**Figure in chapter 9 Quiz Q 3**
what value would you change to assess how much conservation
benefit could be gained by fencing out the deer?
A. 0.7
B. 0.2
C. 0.6
D. 10 Correct Answers D. 10
**10 is the average number of seeds produced per two-year-old
plant, and this is the value that you would change to assess the
potential conservation benefits of fencing out deer.**
,A population of biennial plants (plants that reproduce only in
their second year of life and then die) consists of 150 seeds, 25
one-year-old (vegetative) plants, and 10 two-year-old
(flowering) plants. If the demographic matrix for the population
is
**Figure in chapter 8 Quiz Q 9**
then in the next year the population will consist of
A. 110 seeds, 6 one-year-old plants, and 1,500 two-year-old
plants.
B. 205 seeds, 30 one-year-old plants, and 15 two-year-old
plants.
C. 100 seeds, 30 one-year-old plants, and 15 two-year-old
plants.
D. It is impossible to say given the information provided here.
Correct Answers B. 205 seeds, 30 one-year-old plants, and 15
two-year-old plants.
A restoration project may seek to
A. recreate historical conditions.
B. create habitat for particular species of conservation concern.
C. promote particular ecosystem functions.
, D. achieve any of the above objectives. Correct Answers D.
achieve any of the above objectives.
A well-designed manipulative experiment has all of the
following features, except
A. multiple independent replications of each experimental
condition.
B. random assignment of individual replicates to the various
experimental conditions.
C. background variability that masks any clear signal that might
be attributed to the experimental conditions.
D. efforts to control, or hold constant, any potentially
confounding variables. Correct Answers C. background
variability that masks any clear signal that might be attributed to
the experimental conditions.
**Background variability unrelated to the experimental
treatments is a problem for any study, but a well-designed
manipulative experiment tries to overcome this problem via
replication, randomization, and efforts to control, or hold
constant, potentially confounding variables**
