- Conservation hotspots are best described as a. areas with large numbers of endemic species, in many of which species are disappearing rapidly. b. areas where people are particularly active supporters of biological diversity. c. islands that are experiencing high rates of extinction. d. areas where native species are being replaced with introduced species.arrow_forwardDetermine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardWhich practice would most likely lead to the disruption of an aquatic ecosystem?

- Which of the following could qualify as a bottom-up control on a grassland community? (A) limitation of plant biomass by rainfall amount, (B) effect of grazing intensity by bison on plant species diversity, (C) the effects of predation by wolves on herbivore density, (D) herbivory by moth larvae reducing abundances of certain plant species, (E) agricultural practices by humans eliminating all but one species of grass.arrow_forwardEnvironmental 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.
