Adam Roth Chris Jeyes Brian Rios Megan Nehls Lab 4 Questions 1-4 1. When looking at the survivorship curves of the two human populations in Massachusetts and South Carolina, they are similar yet have some noticeable differences. For example, the S1000 or survivorship per 1000 curves is extremely similar. However, the lx curve in Massachusetts begins much higher than that of South Carolina. They do have the same general curve though. Overall, despite some minor differences in where the curves begin and end, they both take the same general pattern of the Type 1 survivorship curve. 2. The two human examples do fit the general model of Type 1 survivorship curves. The survivorship curve for the lobster population differs slightly but is generally

Unformatted text preview: what is expected of a Type II linear survivorship curve. 3. The two human survivorship curves are high and constant for younger organisms but low for older ones. This suggests that the mortality rate of humans is low and steady for younger people. However, once you get older it is not as steady and you have a greater chance of reaching death. (Unfortunately) 4. The human survivorship curves suggest that perhaps our ability to survive at older ages could increase if the strongest people continue to reproduce and pass on their strong genes. Maybe then we will see an increase in survivorship for our overall population in America and in the world....
