What is the net reproductive rate in this population? b. What is the average age at which females give birth to their offspring? c. Estimate r from the net reproductive rate and the estimated length of the generation: d. What is your estimate of 2 in this case? Question 7 continued on next page

Explanation / Answer

(a)Net reproductive age = 0+0.60+1.80+1.08+0.20 = 3.68

3.68 is the net reproductive age.

(b) average age at which female give birth = 0+1+6+9+8/5 = 4.8

So ,4.8 is the average age at which female give birth to offspring.

(c) r = dN/dt

3.68/10

r=0.368
