An ecologist recorded 12 white-tailed deer, Odocoileus virginianus, per square mile in one woodlot and 20 per square mile on another woodlot. What was the ecologist comparing?

• dispersion
• carrying capacity
• quardrats

During the spring, you are studying the mice that live in a field near your home. There are lots of mice in this field, but you realize that you rarely observe any reproductive females. This most likely indicates

• a. that there is selective predation on female mice.
• that female mice die before reproduction
• that this habitat is a good place for the mice to reproduce
• that you are observing immigrant mice.

To measure the population density of monarch butterflies occupying a particular park, 100 butterflies are captured, marked with a small dot on a wing, and then released. The next day, another 100 butterflies are captured, including the recapture of 20 marked butterflies. One would estimate the population to be

• 200
• 500
• 1,000
• 10,000

You are observing a population of lizards when you notice that the number of adults has increased and is higher than previously observed. One explanation for such an observation would include

• increased immigration
• decreased emigration
• decreased emigration

The most common kind of dispersion in nature is

• clumped
• uniform
• random
• inderminate

Uniform spacing patterns in plants such as the creosote bush are most often associated with

• chance
• patterns of high humidity.
• competitive interactions among individuals in the population
• the random distribution of seeds

Which of the following groups would be most likely to exhibit uniform dispersion?

• red squirrels, who actively defend territories
• cattails, which grow primarily at edges of lakes and streams
• dwarf mistletoes, which parasitize particular species of forest tree
• moths in a city at night

A table listing such items as age, observed number of organisms alive each year, and life expectancy is known as a (an)

• motality table
• life table
• survivorship table
• rate table

Life tables are most useful in determining which of the following?

• carrying capacity
• the fate of a cohort of newborn organisms throughout their lives
• immigration and emigration rates
• population dispersion patterns
