Insects are the largest group of animals on Earth. Insectdiversity is greatest in the tropics, where habitat destructionand species extinction are occurring at an alarming rate.What biological, economic, and ethical arguments can youadvance to persuade people and governments to preservethis biological diversity?

5. Most remote oceanic islands have at least one uniquespecies of fl ightless bird that shows little or no fearof humans or other large predators. Account for thisobservation.
Many species of animals make alarm calls, whichwarn others in their group that a predator isapproaching. Alarm calls also attract the attention of the predator, making it more likely thatthe individual making the call will be eaten. Whymight natural selection favor the evolution ofalarm calls in a species? How might you test thathypothesis?
amphibian populations are decliningrapidly worldwide. the fungus Batrachochytrium dendrobatidis (Bd) has contributedto this decline: this pathogen causes severeskin infections in many amphibian species,leading to massive die-offs. efforts to saveamphibians from Bd have met with limitedsuccess, and there is little evidence thatfrogs and other amphibians have acquiredresistance to Bd on their own.
The Barton Springs salamander is an endangered species found only inthree adjacent springs in the city of Austin, Texas. There is growingconcern that a chemical spill on a nearby freeway could pollute thespring and wipe out the species. To provide a source of salamanders torepopulate the spring in the event of such a catastrophe, a proposal hasbeen made to establish a captive breeding population of the salamanderin a local zoo. You are asked to provide a plan for the establishment ofthis captive breeding population, with the goal of maintaining as muchof the genetic variation of the species as possible. What factors mightcause loss of genetic variation in the establishment of the captivepopulation? How could loss of such variation be prevented? With theassumption that only a limited number of salamanders can bemaintained in captivity, what procedures should be instituted to ensurethe long-term maintenance of as much variation as possible?
Scientists have studied, in detail, the evolution of the peppered moth, Biston betularia, over the last two hundred years. The peppered moths rest on tree trunks and are a tempting treat for birds in the area. In the mid-1800s the trees in their England habitat were covered with lichens, which are a light, grayish-green color. Although color variations occurred, the vast majority of the moths were light-colored. Because their light coloration effectively camouflaged them against the lichens-covered trees, they were not as easily seen by birds as darker colored moths. The light colored moths flourished.The environment changed, as the Industrial Revolution progressed. By 1900, the lichens had died and trees were coated with soot due to industrial pollution. The lighter colored moths were no longer "hidden" in their environment, and in fact, were easily seen by their predators. Their numbers dwindled. At the same time, the darker-colored moths flourished because of their ability to hide…

Which row below best describes why the population of adult mosquitoes would drop so dramatically during this time period Feb. 5, 2007 Something is wiping out honey bees across North America and a team of researchers is rushing to find out what it is. What’s being called Colony Collapse Disorder (CCD) has now been seen in Pennsylvania, North Carolina, Florida, Georgia and way out in California. Some bee keepers have lost up to 80 percent of their colonies to the mysterious disorder. Whatever kills the bees targets adult workers, which die outside the colony — with few adults left inside, either alive or dead. The disorder decimates the worker bee population in a matter of weeks. Aside from making honey, honey bees are essential for the pollination of tens of million of dollars worth of cash crops all over the United States. That’s why almond growers of California, for instance, are taking notice and pledging funds to help identify and fight the honey bee disorder. Among the…
