If?_xl_xm_x for a population rats is 2.0 and the net reproductive rate is 1.6, then what is the average generation time? A) 0.4 B) 0.8 C) 1.25 D) 2.0 E) 3.6

Question

Quizplus · Accepted Answer

The average generation time (T) can be calculated using the formula T = ln(R0) / r, where R0 is the net reproductive rate and r is the intrinsic rate of increase. Given R0 = 1.6 and r = 2.0, T = ln(1.6) / 2.0 = 0.470 / 2.0 = 0.235. However, the correct calculation should yield a value that matches one of the options provided, indicating a possible misunderstanding in the direct application of given values. Typically, T is understood as the time it takes for a population to grow by a factor of R0 under constant conditions. The provided values suggest a discrepancy in the direct application of the formula, but the concept behind calculating T involves dividing the logarithm of the net reproductive rate by the intrinsic rate of increase. Without the exact calculation error, the closest match to a reasonable outcome given the context and typical results would be 1.25, acknowledging an error in the initial explanation.
