The field of conservation biology ________.

Read the statement below carefully. Answer True if you think a statement it TRUE. Answer False if you think the statement is FALSE. Give a brief explanation or example to justify your answer. Paul Ehrlich, and environmentalist, views unchecked population growth as a problem.

Read the following scenario and answer the question below. Human activities, including fossil fuel combustion, farming, and deforestation, are known to increase the levels of carbon dioxide, methane, and nitrous oxides in our atmosphere. Measurable warming of Earth due to these greenhouse gases can alter ecosystem dynamics. In addition to the direct climatic effects on organisms within biomes, warming can lower levels of sea ice and increase precipitation in Arctic areas. Global warming can also melt permafrost in the tundra and increase sea surface temperatures, which could increase the intensity of hurricanes in vulnerable areas. Within communities, climatic change can shift interdependent species “out of sync,” potentially causing indirect loss of species. For example, if pollinators and the plants they pollinate become out of synch, the pollinators may not be able to switch to a different food source, and the plants may not be able to reproduce. Global warming has been hypothesized to cause many plants to flower earlier. If bees search for food earlier in response to this, this would represent ________ within the community.

Read the following scenario and answer the question below. Many biologists and environmental educators are interested in maintaining biodiversity in urban landscapes, where preserves or reserves are scarce unless land has been set aside for them in urban planning. Nonetheless, they have discovered that making even small changes in commercial and residential landscaping can help promote biodiversity. Some of the changes that have been successful include using native species for street trees and for decorative landscaping, reducing pesticide use on lawns and gardens, and reducing fertilizer use through composting and mulching. Also, managers of schools, larger businesses, and residences are encouraged to increase habitat diversity by creating “landscape islands” that include larger trees surrounded by shrubs and herbaceous plants. Landscape islands ideally should include native species, mixed with exotic ornamentals at the discretion of the land owners. From your experiences with the lawn and the butterfly garden, you can affirm that ________.
