1. Which group is not a population? all four groups are populations
2. How would you estimate the num- mark and recapture
ber of whales in a population?
3. What is a population? a group of individuals of the same
species living in the same area at the
same time
4. True or False? Sampling quadrats false
would be the better method for es-
timating the number of whales in a
population.
5. True or False? Mark and recapture true
would be the better method for es-
timating the number of saguaros in
a population.
6. True or False? The shrinking popu- true
lation between 1965 and 1970 could
have resulted from a decrease in
the birth rate or an increase in the
death rate.
7. True or False? The growing popula- true
tion between 1985 and 1995 could
have resulted from a decrease in
emigration or an increase in immi-
gration.

11. True or False? The carrying capac- true
ity of a population depends on the
resources available in the environ-
ment.
12. Why do bluegills nest on the edge The habitat in the shallow water might
of the lake? receive more solar radiation, holds
more zooplankton (which is what they
eat), more protective over young than
it in deeper water where larger fish re-
side, more algae for the fish to hide in,
warmer water for embryos to develop
quickly and enhance survival/fitness.
13. Activity: Write a Figure Legend Bluegills prefer certain water temp;
when given a choice between 27 de-
grees celsius and 31 degrees celsius,
bluegills spent a majority of their time
at 31 degrees celsius.
14. True or False? If males compete for true
space, a large male will likely force
a small male to spend less time on
the side of the tank with the optimal
temperature.
15. True or False? Both models as- false
sume that no individuals immigrate
into the population.
16. t/f: When possible, a bluegill true
prefers to have a body temperature
around 31°C.
17. T/F: When competing with an adult, False (If the environment hotter than
a juvenile bluegill will always have preferred, on average, large bluegill
a lower body temperature than its will force small bluegills to remain in
preferred temperature. parts of water that are hotter than pre-
ferred)

18. T/F: All else being equal, the carry- true
ing capacity of a lake would likely
increase as more parts of the lake
warm to 31°C.
19. T/F: All else being equal, a juvenile true
bluegill will likely grow slower in a
lake with many adult bluegills than
in a lake with few adults
20. T/F: The growth of a bluegill pop- false, Because access to suitable tem-
ulation would be better described peratures is limited, the growth of the
by a model without density depen- population will have a carrying ca-
dence than by a model with density pacity, which requires density depen-
dependence. dence
21. T/F: The number of whales was false
more likely estimated by sampling
than by mark-recapture.
22. T/F: The shrinking population be- true
tween 1965 and 1970 could have re-
sulted from a decrease in the birth
rate or an increase in the death
rate.
23. T/F: The growing population be- true
tween 1985 and 1995 could have
resulted from a decrease in emigra-
tion or an increase in immigration.
24. T/F: Between 2005 and 2008, the true
sum of the birth and immigration
rates roughly equaled the sum of
the death and emigration rates.
25. T/F: The growth of this population false
would be described well by an ex-
ponential model.
