Question

A fecundity table is constructed for a gray squirrel: _____________________

x lx bx lx bx
0 1.0 0.0 0.00
1 0.3 2.0 0.60
2 0.15 3.0 0.45
3 0.09 3.0 0.27
4 0.04 2.0 0.08
5 0.01 0.0 0.00
On the basis of these calculations, the net reproductive rate (R0) is equal to
A) 1.4.
B) 1.59.
C) 10.
D) 15.

Answer 1

The net reproductive rate (R0) can be calculated using the fecundity table provided. R0 is calculated as the sum of the products of lx and bx for each age class, where lx represents the proportion of individuals alive at a certain age and bx represents the average number of offspring per individual at that age. In this case, the net reproductive rate (R0) is equal to 1.59.

Step-by-step explanation:

The net reproductive rate (R0) can be calculated using the fecundity table provided. R0 is calculated as the sum of the products of lx and bx for each age class, where lx represents the proportion of individuals alive at a certain age and bx represents the average number of offspring per individual at that age.

In this case, R0 can be calculated as: (1.0 * 0.0) + (2.0 * 0.3) + (3.0 * 0.15) + (3.0 * 0.09) + (2.0 * 0.04) + (0.0 * 0.01) = 1.59.

Therefore, the net reproductive rate (R0) is equal to 1.59. Option B is correct.
