The main parameter of the life table is represented by the intrinsic rate
of population increase ([r.
738 (log e Md) / d, the mean intrinsic rate
of increase (rm) for each plant was calculated, where Md is the total number of progeny produced by [P1] the mother of F1, (d) is the time taken by F1 aphid from its birth till the production of its 1st offspring.
frugiperda fed in reproductive structures of YieldGard VT PRO[TM] and PowerCore[TM] corn reduced the intrinsic rate
of increase (rm) by 10 and 15%, respectively.
T]), the intrinsic rate
of increase or the innate ability to increase ([r.
Three-dimensional isopleth plots were constructed to assess the response of the conditional intrinsic rate
of population increase parameter, r, to different inputted combinations of fishing mortality and the age at which 50% of sharks were selected.
Total comparison of parameters including: net reproductive rate, intrinsic rate
of increase, generation time and doubling time showed that the cowpea was more sensitive host in comparison with others.
No correlation was found in either treatment for any trait with the intrinsic rate
Number of significant second-order models per 1000 time-series simulations for the Ricker model under 18 combinations of the parameters, r and [Psi], using two analyses (r = the intrinsic rate
of population increase; [Psi] = the autoregressive parameter of the exogenous factor).
The DDD(R)+ algorithm was designed to optimize overdrive pacing while minimizing patient symptoms by pacing the atrium at rates slightly above the intrinsic rate
The intrinsic rate
of increase (rm) was positively correlated with the temperature up to 25[degrees]C (Table 1), where it reached a peak (P > 0.
Key words: Chrysoperla carnea development time intrinsic rate

birgei populations was compared by determining their intrinsic rate
of natural increase under defined laboratory conditions, according to the following equation (Odum, 1985):
