Tetranhychus bastosi fertility life table Fertility life table parameters were obtained regarding the net reproduction rate (Ro), intrinsic growth rate (r m), duration of one generation (T), finite rate of increase (λ), stage-age specific survival (sxj), survival rate (lx) and specific fecundity (mx). Data were analyzed based on stage and age, using the Two-sex life table statistical package (Chi 1988) and the TWOSEX-MSChart program (Chi 2017). Population standard errors were estimated using the bootstrap method. A number equivalent to 100,000 bootstraps was used to obtain stable estimates of standard error. The paired bootstrap test was used to compare statistical differences (Efron and Tibshirani 1993). The computer program TWOSEX-MSChart (Chi 2017) was used for the analysis and calculation of population parameters. |
