Chapter 46, Problem 3MIR

How can investment in a large, charismatic species also favor the conservation of other species?

What is mainly responsible for the extinction of wildlife?

How might your own behavior influence the influx and ecological impacts of non-native species like those listed above? Name three things you could personally do to help reduce the impacts of invasive species.

Based on the intermediate disturbance hypothesis, a community's species diversity is increased bya) frequent immigrations of new speciesb) moderate levels of disturbancec) intensive disturbance by humansd) stable conditions with no disturbance

What kind of conservation strategies have been or should be implemented to the Hawaiian islands in order to avoid native bird populations declining or going extinct due to avian malaria?

What is one way in which temporal changes in community species composition negatively impact delivery of an ecosystem service?

What are the implications of the "bottleneck effect" for wildlife managers who try to help endangered species, such as the whooping crane, recover from near extinction?

Environmental scientists David Pimentel, Rodolfo Zuniga, and Doug Morrison of Cornell University reviewed scientific estimates for the economic and ecological costs imposed by introduced and invasive species in the United States. They found that, as of 2005, approximately 50,000 species had been introduced in the United States and that these accountedfor over $120 billion in economic costs each year. These costs include direct losses and damage, as well as costs required to control the species. (The researchers did not quantify monetary estimates for losses of biodiversity, ecosystem services, and aesthetics, which they said would drive total costs several times higher.) Calculate values missing from the table to determine the number of introduced species of each type of organism and the annual cost that each imposes on our economy. Of the 50,000 species introduced into the UnitedStates, half are plants. Describe two ways in whichnon-native plants might be brought to a new location.How…

What is the relationship between a pioneer species and primary succession?         A pioneer species is an invasive species that causes areas to experience primary succession.          There is not a relationship between a pioneer species and primary succession. The pioneer species only occurs in areas of secondary succession.         A pioneer species is important in an area of primary succession because it can grow and thrive in areas where most other species cannot.          A pioneer species only inhabits areas of primary succession.
