Exam 18: Biogeography

Refer to the figure. - The equilibrium point for species diversity on a small island near the mainland would be represented by which letter?

Which of the following is a finding of the Biological Dynamics of Forest Fragments Project (BDFFP)?

Refer to the figure. Figure 3 Figure 3 shows long-term patterns of continental movement for five large land masses, illustrating the location of the land masses during an active period of land mass movement, at about 40 mya. The arrows indicate the direction of land mass movement and the numbers indicate the approximate timing (mya) of these events. Based on Figure 3, describe the mostly likely path of land mass 5 through time by answering the following questions: a) Which land masses was land mass 5 most likely joined with 150 mya? b) Which other land masses was land mass 5 joined with 50 mya? c) Which other land mass(es) was land mass 5 joined with 30 mya?

Refer to the figure. - Which biogeographical region is represented by X?

Which of the following is not a finding from the study on local and regional species richness by Witman et al. (2004)?

Which climatic zone has the greatest land area?

The fly species Drosophila santomea is found only on a single small island. Thus, this fly is considered to be

Refer to the table. The table shows the number of species of a group of mammals present in the tropics, the subtropics, and the temperate zone over the last fifty million years. - Of the three broad categories of hypotheses that have been proposed to explain latitudinal gradients (diversification rate, diversification time, and productivity or carrying capacity), these data most clearly fit which hypothesis?

Refer to the figure. Figure 3 Figure 3 shows long-term patterns of continental movement for five large land masses, illustrating the location of the land masses during an active period of land mass movement, at about 40 mya. The arrows indicate the direction of land mass movement and the numbers indicate the approximate timing (mya) of these events. Use the direction of the arrows and the timing of the events to answer the following questions: a) When did land mass 2 split from land mass 4? b) Which land masses joined between 180 and 20 mya? c) Which land masses joined most recently? d) What process could account for the movements of these land masses?

Refer to the figure. Which of the following statements is most clearly supported by the data in the figure?

Which statement about plate tectonics is true?

Refer to the figure. The figure shows the relationship between size of habitat and the number of mammalian species. According to the figure, we would expect a habitat that is 1,000 square kilometers to have _______ species of mammals.

Which statement about the equilibrium model of island biogeography is false?

Which statement about Simberloff and Wilson's test of the equilibrium theory of island biogeography using small mangrove islands in the Florida Keys is true?

Which statement about the Biological Dynamics of Forest Fragments Project (BDFFP) is false?

Refer to the figure. - Which biogeographical region is represented by Y?

At the end of the Permian period (about 250 mya), Earth's land masses

Refer to the table and figure. Table 2 Figure 4 You are studying the long-term effects of plate movement for two land masses, land mass A and land mass B. Your goal is to understand how land mass movement has affected the species found on each land mass. Land mass B joined with land mass A 30 million years ago. Table 2 shows the number of individuals of each species (species A-F) found living on land mass B over time. Figure 4 shows these data plotted. -Use the data in Table 2 and Figure 4 to answer the following questions: a) Sketch a vertical line on Figure 4 to indicate the time when land masses A and B joined (this will be referred to as Figure 5). b) Which species on land mass B became extinct before land masses A and B joined? c) Which species on land mass B became extinct after land masses A and B joined? d) Which species was not originally found on land mass B but could have dispersed there from land mass A following the joining of the two land masses? e) Which species showed no change in the number of individuals as a result of the joining of the two land masses?

Which statement about regional scale is true?

Refer to the figure. Figure 3 Figure 3 shows long-term patterns of continental movement for five large land masses, illustrating the location of the land masses during an active period of land mass movement, at about 40 mya. The arrows indicate the direction of land mass movement and the numbers indicate the approximate timing (mya) of these events. Determine the most likely locations for the following geologic features and answer the following questions: a) The oldest mid-ocean ridge would be between which land masses? b) Subduction zones would be between which land masses? c) Which two areas would have the most recent mountain ranges?
