In your textbook, the survivorship curve of the mountain dusky salamander presented in Figure 9.11 is like the General Pattern of Survivorship discussed in the Characteristics of Population lecture except that the mountain dusky salamander survivorship curve is missing one of the three segments, curve c (yellow) Identify the missing segment and speculate on why it is missing. Do you think that this is typical of most wild animals or is it unique to mountain dusky salamanders? Explain
