- Q1Population ecologists are primarily interested inunderstanding how biotic and abiotic factors influence the density, distribution, size, and age structure of populations.how populations evolve as natural selection acts on heritable variations among individuals and changes in gene frequency.how humans affect the size of wild populations of organisms.studying interactions among populations of organisms that inhabit the same area.30s
- Q2An ecologist recorded 12 white-tailed deer, Odocoileus virginianus, per square mile in one woodlot and 20 per square mile in another woodlot. What was the ecologist comparing?dispersioncohortsdensitycarrying capacity30s
- Q3During the spring, you are studying the mice that live in a field near your home. The population density is high, but you realize that you rarely observe any reproductive female mice. This most likely indicatesthat there is selective predation on female mice.that this habitat is a good place for mice to reproduce.that you are observing immigrant mice.that female mice die before reproducing.30s
- Q4Which of the following sets of measurements is the most useful when studying populations?gene frequency over time and the ratio of reproductive to nonreproductive individualsannual precipitation averages and mean annual temperaturesdensity, dispersion, and demographics of a populationminimum and maximum amounts of precipitation and annual temperature extremes30s
