choose a plant or animal species that is not currently in your ecosystem, and think of how this species might realistically migrate into the ecosystem you studied. Describe some of the abiotic and biotic factors in the ecosystem that would affect the species. Do you think this species would become extinct or thrive in your ecosystem?

The Gulf of St. Lawrence is home to the beluga whalesThere once were thousands of belugas in this popula tion, but now there are fewer than 1000 whales.

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?
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?
Species richness of many taxa (birds, trees, etc.) increases from the poles to the equator. Ecologists do not know exactly why, but the following idea(s) is/are well supported by evidence: Question 11 options: - The warmer climates of the tropics have longer growing seasons, more primary productivity and more benign climates which produce a larger resource base for more species and may increase specialization. - Polar and temperate regions have had to “start over” many times after successive glaciations, so species have had to re-colonize those areas. - Extinction rates are lower in tropical areas than temperate areas. --- First and Second Answers are BOTH true. --- Second and Third Answers are BOTH true

Australian researchers removed a parasitic plant called mistletoe froma forest and observed the consequences. During the 3-yearexperiment, over 30% of the insect and bird species disappeared fromthe mistletoe-free forest. Another forest in which no mistletoe wasremoved saw no change in species diversity. What might the biologistsconclude from these data?
Anthropogenic Land-use. A. Human activity engineers landscapes into a highly heterogenous environments which according to the biodiversity global patterns (specie area curves) should drive up the number of species present in that landscape. Explain why this is not the case in human dominated landscapes. B. How does fragmentation drive decision making in land conservation? is there a better approach, over others, for anthropogenic landscapes? (hint -SLOSS) C. Why do mainland (continental islands) generally support greater diversity than oceanic islands? reason your opinion.
