    Notes: Abstract The present paper adds further notes on the biology of Cyclestheria hislopi (Baird). An attempt has been made to study the variation in the natural population of this species based on its birth-rate. C. hislopi has dist inct preference for the plant Hydrilla verticellata (Royle) on which they remain attached. It is considered completely parthenogenic, having no males. The period from October to January can be considered to be the growth period for this species, after which the population declines. This decline has been found to be due to the low birth-rate exhibited during the subsequent months.

    Notes: Of the experimental methods available for obtaining data to estimate the biological kinetic parameters μm, Ks, and Yeach requires considerable experimental effort, yet often yields somewhat imprecise estimates of the parameters, particularly Ks. Therefore it would be worthwhile to seek ways to get parameter estimates of greater precision using less experimental effort. The precision of parameter estimates is strongly dependent, upon the settings of the independent, variables used in the experiments. This dependence is explained and an attempt made to show how experimental settings can be determined that lead efficiently to precise parameter estimates with minimal effort.

    Using multiresponse data to estimate biokinetic parameters (1975)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Biokinetic parameters are usually calculated from slopes and intercepts taken from plots of experimental data. One response at an item is plotted and used for parameter estimation. Aside from problems that may be caused by transformations made when the data are plotted, this approach has the weakness of not using all the data simultaneously when there is more than one response. This paper shows how multiresponse biological data can be handled to get parameter estimates that are much more precise than those obtained using conventional methods.
