- A population is CORRECTLY defined as having which of the following
inhabiting the same general area, individuals belonging to the same species
- 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?
density or population density
- 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
500
- 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
that you are observing immigrant mice
- 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
- Uniform spacing patterns in plants such as the creosote bush are most often associated with
competitive interactions among individuals in the population
- Which of the following groups would be MOST likely to exhibit uniform dispersion?
red squirrels, who actively defend territories
- The most common type of dispersion in nature is
clumped
- In order to construct a reproductive table for a sexual species, you need to
keep track of the females in a cohort
- Which of the following examples would MOST accurately measure the density of the population being studied?
counting the number of zebras from airplane census observations
