- Tourism and its effects, like pollution from hotels and the impact of boats and tourists, on fragile habitats often clash with conservation efforts. Sometimes, however, tourism can help. The economic impact of banning the hunting of harp seals in eastern Canada has been compensated for, in part, by the influx of tourists who now go to see the seals. Can you think of other examples? What recommendations can you make to minimize the impact of tourism on unspoiled marine environments?Given the data collected by a recent Australian government study on the Great Barrier reef we recognize humans have protected the reef and it is now a model for restoration projects, worldwide. humans are killing the reef through acts of violence so discrete they are unable to be quelled by even military forces. humans are indifferent to the status of the reef. humans are destroying the reef through their own generated pollution. it is a relatively easy task to restore the world landmark.Species diversity is highest at what level of marine ecosystems? A) Open Sea Coastal Zone C) Benthic Zone D) Intertidal Zone
- A forest fire destroys a large section of a mature forest. Several years later, the area is covered with a mix of grasses, shrubs, and small trees. The process of ecological recovery in this forest is characterized by the re-establishment of complex plant communities. 1) Is this an example of primary or secondary succession? 2) Which stage of ecological succession is most likely represented by this scenario? Intermediate stage Alternative stable stage Pioneer stage Climax Community StageIf you are one of the environmentalists and was assigned in one of the forests in the Philippines which happened to be the location of some endangered species, what are the plans that you would organize to ensure the conservation of the species of the flora and fauna present in your assigned area?Describe the San Francisco Estuary Project. How has population growth in the San Francisco Bay Area affected the estuary? How has the habitat fracture in the San Francisco Estuary been increased by human behavior? How is the project focusing on maintaining the biodiversity of plants and animals in the San Francisco Estuary?
- Wilderness preserves are relatively clear and immediate ways of protecting endangered species and ecosystems. To what extent should this make them a priority or a go-to tool?Many ecosystems have already been fragmented into habitat islands. What kinds of natural or non-natural barriers may create land ‘islands’? What can be done to improve biodiversity in situations like this?Site A Site B Site A7 Species Site B = 5 Species *A*+* + Site C7 Species A Site C A vs B = 8 species B vs C = 6 species A vs C = 10 species A developer owns the property encompassing the three habitats above. By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision? Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species. Site C has more unique species in it than either Site A or…
- 4) The figure below displays the three levels of biodiversity. Please label them and the answer the questions below. a) How are these related to one another? What would happen if one or more then one was throw off? b) What are ecosystem services and why are they important to humans? What is an example of an ecosystem service?Which is an example of secondary succession? Mark only one oval. A) Beach grasses colonize a newly formed sand dune. B) Retreating glaciers leave alluvial soils for cottonwood trees to colonize. C) A shift in river flow introduces sediment to a rocky area. D) A farmer allows an agricultural field to return to native grassland. An old pine tree in someone's front yard is beginning to die as the neighborhood deciduous trees have grown in abundance and size. Based on the ideas of the concept of succession, why might this be? Mark only one oval. A) Deciduous trees have depleted the soil of nutrients. B) The pine tree is shade intolerant. C) The pine tree has depleted the soil of nutrients. D) Deciduous trees are shade intolerant. E) Salt water most likely has intruded the area The number of species within a community is usually greatest when which of the following occurs?
