A biologist determines the growth rate of a population of 198 frogs in a marsh near
Beaverhill Lake, Alberta, to evaluate the quality of the environment. The researcher finds
that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no
emigration.
a. frogs are considered an indicator species for the quality of the environment. Determine whether the growth rate of this population in one year is a cause for concern. if so, what might the concerns be?
Carrying capacity is defined as a species’ average population size in an environment. Which of the following resulted to exceeding carrying capacity in a particular environment?
a.
increasing birthrates, decreasing deathrates, increasing immigration and no emigration takes place
b.
increasing birthrates, decreasing deathrates, decreasing immigration and no emigration takes place
c.
increasing birthrates, decreasing deathrates, decreasing immigration and increasing emigration
d.
decreasing birthrates, increasing deathrates, increasing immigration and increasing emigration
Conservation hotspots are best described as
a. areas with large numbers of endemic species, in many of which species are disappearing rapidly.
b. areas where people are particularly active supporters of biological diversity.
c. islands that are experiencing high rates of extinction.
d. areas where native species are being replaced with introduced species.
