question 32

Essay

Refer to the figures.
Figure 1
Figure 2
Figure 3
You are evaluating three snail species to determine their overall threat as invasive species to an area. You bring several individuals of each species into your lab to test their tolerance of a range of abiotic and biotic factors. Figure 1 shows how the three snail species respond to differences in average temperature and Figure 2 shows the number of prey and parasite species for each of the species in the new areas, along with how competitive each potential invasive species will be in the new community (higher numbers indicate that the species will be a more successful competitor).
-Suppose a fourth snail species (Species D) has successfully invaded six different communities. The average summer temperatures for species D's native area and the six areas it invaded are shown in Figure 3 (columns indicate average temperatures; error bars indicate the total range of temperatures). What insight do these data provide into the biology of Species D? Compare Species D's ability to tolerate the conditions in these new areas and successfully invade the communities to the case of the Caulerpa seaweed that invaded the Mediterranean. Which factors explain how Species D was able to colonize these new areas, and how similar is this to the case of Caulerpa? Justify your answer.
