When Arizona's Grand Canyon formed, squirrels and other small mammals that had once been part of a single population could no longer contact and reproduce with each other across this new geographic barrier. They could no longer interbreed. On the other hand, birds and other species that could easily cross this barrier continued to interbreed. Predict the long-term effect the formation of the Grand Canyon may have had on squirrel and bird species over time. *

Imagine that you are asked to manage a population of wolves that have taken upresidence on an island off the coast of Alaska. Because prey resources are limited, theisland will support only about 50 wolves at any one time. What steps would you take toprevent inbreeding and genetic drift in the population in the future?

Gray whales ( Eschrichtius robustus) gather each winter near BajaCalifornia to give birth. How might such behavior make it easierfor ecologists to estimate birth and death rates for the species?
Consider two species that diverged whilegeographically separated but resumed contactbefore reproduction isolation was complete. Predictwhat would happen over time if two species matedindiscriminately and a. hybrid offspring survived and reproducedmore poorly than offspring from intraspecificmating or b. hybrid offspring survived and reproduced aswell as offspring from intraspecific mating.Provide an example for each to illustrate yourpoint.
. Could natural selection, at any level of organization, ever cause the extinction of a population orspecies?
Perhaps 98 percent to 99 percent of all species that have ever existed areextinct. Nearly all went extinct long before humans arrived on the scene. Whyshould we be concerned about the extinction of organisms today?
The geological record indicates that over the course of the last 510 million years, the Earth has seen at least _____ mass extinction events.
True or false: Adaptive radiation can itself set conditions for mass extinction
