The age-stage, two-sex life table 与传统生命表的比较:

Age-Stage, Two-Sex Life Table?  Why?

1.    Both sexes are important.  Male lady beetles can also kill aphids. Age-stage, two-sex life table takes both sexes into consideration.

a)    The developmental rate of males may different from that of females.

b)    The predation rate of male lady beetle may be different from that of females.

c)    Only using the age-stage, two-sex life table can give a correct description for the predator-prey relationship?

2.    Correct stage grouping is important.  If you use traditional age-specific life table, it is impossible to group the stage properly.

a)    Stage differentiation is an important phenomenon for insects.  Insects of different stages have different consumption rate and thus cause different economic injury.

b)    The susceptibility to pesticide and vulnerability to predator are different for individuals of different stages.

3.    Both the mean fecundity (F) of female and the net reproductive rate (R0) are calculated based on the daily fecundity of female.   There must be a reasonable relationship.  Can you find the relationship?  Age-stage, two-sex life table gives correct relationship between the mean fecundity and the net reproductive rate.

4.    Proper handling the preadult mortality is important.  If you use the age-specific female life table, you will face the problem of preadult mortality.  Most scientists just assumed a 0.5 sex ratio. But, is it OK?

5.    Is it correct to use the “adult age”?  Will it result in errors in your lx and mx?

The age-stage, two-sex life table gives a correct, complete, and comprehensive description on the stage-structured demography.
