The term "n" refers to the size of a population, that is, the number
of individuals in that population. In general, in a sample of n
individuals, the frequency of an allele is

The goldenrod gall fly lays its eggs on the terminal buds of
goldenrod plants. Larvae chew through the buds and into the stems,
where their saliva induces the plant to generate a gall (an outgrowth
of tissue). This gall then provides food and shelter for the
developing larva. The larvae are prey of both parasitoid wasps and
birds. Wasps selectively prey on larvae inside the smallest
galls while birds selectively prey on larvae inside the largest galls.
Goldenrod gall flies are therefore subject to
Under the "business as usual" model of climate change, will temperatures change uniformly across the
globe? Examine Figure 48.7 in your text and compare the projected change in temperature in central South
America and central Africa at the equator (draw an imaginary line across the globe at its widest point and
examine a spot in the middle of each continent along that line). Which of the following best describes the
predicted changes?
Banner-tailed kangaroo rats, Dipodomys spectabilis, are rodents endemic to (found only in) the deserts of the southwestern United States. Which of the following is the best description of their niche?a seed-eating rodents that compete with other seed-eating organisms for foodA species' _____________ niche comprises the full range of climate conditions and food resources that permit the individuals in a species to livefundamental_____ are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called _____.a. Symbioses; mutualismsCompetition occurs:between members of the same species and between members of different speciesIn the late 1960's, Robert Paine conducted landmark studies on diversity in the rocky intertidal zone, comparing the species diversity in control plots with diversity in experimental plots from which he removed the top predator, sea stars. After 5 years, 15 species of intertidal invertebrates lived in the control plots, while the experimental plots were dominated by only two species, one mussel and one barnacle. The process most likely responsible for the loss of species diversity in the experimental plots was:competitive exclusionA large population made of smaller populations linked by migration is a __________________.metapopulationThe common mud turtle experiences relatively uniform mortality rates throughout its life. This is a type _____ survivorship.Correct Answer(s): a. II b. 2 c. twoWhat are the units of r ?change in individuals per unit time/individuals at starting timeWhen a population is small relative to its carrying capacity, its growth will initially be _________ and shift to ________ as it continues to grow.exponential; logisticAs populations approach carrying capacity, crowding can affecta. birth and death rates through resource limitation, and death rates by increasing the transmission of pathogens and parasites.
