Species often arrive at an area by catching a ride on other species—including hosts. For example, a strain of cholera common in Nepal was introduced to Haiti in 2010 by infected UN workers who traveled from Nepal to Haiti. With respect to the cholera pathogen, what type of dispersal is this an example of?

Please use the following information to answer the question(s) below.Three forest areas are being considered for a conservation reserve. Each area contains the same number of trees and is the same cumulative size. The area surrounding the forest patches is a mix of agricultural land and residential homes.The American lady butterfly (Vanessa virginiensis) inhabits only forest edges and does not disperse well across unsuitable habitat. Which of the following area(s) would support the highest numbers of this butterfly?

Bullfrog tadpoles are often sold as fish bait, even in areas where they do not occur naturally. When people buy 10 of them and don’t use them all, they often dump the remainder into the lake or river. This is an example of ________.

Use the figure above to answer the following question(s).Direct consequences of biodiversity loss are ________.

The term biologists use to describe the species diversity in a specific location is

Please use the following information to answer the question(s) below.Three forest areas are being considered for a conservation reserve. Each area contains the same number of trees and is the same cumulative size. The area surrounding the forest patches is a mix of agricultural land and residential homes.Which area(s) would be most suitable for conserving amphibians, which are highly susceptible to a pathogenic (disease-causing) chytrid fungus?

Which of the following would be most vulnerable to extinction?

In the following figure, the isthmus separates the Pacific Ocean on the left (side A) from the Caribbean (Atlantic Ocean) on the right (side B). The seawater on either side of the isthmus is separated into five depth habitats (15), with 1 being the shallowest.Which of these habitats is likely to harbor the most recently diverged species?

Overharvesting or overexploitation encourages extinction and is most likely to affect

Figure 23.3According to the theory of seafloor spreading, oceanic islands, such as the Hawaiian Islands depicted in Figure 23.3, form as oceanic crustal plates move over a stationary “hot spot” in the mantle. Currently, the big island of Hawaii is thought to be over a hot spot, which is why it is the only one of the seven islands that has active volcanoes. What should be true of the island of Hawaii?1. Scientists in search of ongoing speciation events are more likely to find them there than on the other six islands.2. Its species should be more closely related to those of nearer islands than to those of farther islands.3. It should have a rich fossil record of terrestrial organisms.4. There is a good chance of finding endemic species on this island.5. On average, it should have fewer species per unit surface area than the other six islands.
