Dear Rich, It depends how the data is generated. Although I am not an expert in ecology, I can explain it based on a biomedical example. Certain variables are generated geometrically (exponentially), e.g. MIC or Titer. MIC = Minimum Inhibitory Concentration for bacterial resistance Titer = dilution which still has an effect, e.g. serially diluting blood samples; Obviously, diluting the samples will generate the following concentrations: 1, 1/2, 1.4, 1/8, 1/16, ... (or the reciprocal: 1, 2, 4, 8, 16, ...) It makes no sense to compute th...

Respected Sir/Madam, I have a question regarding calculation of LD50 (Lethal Dose) and IC50 (50% inhibitory concentration) of an antimicrobial experiment. I have used a compound isolated from a plant and observed its effect on the fungus *Fusarium oxysporum* by the food poisoning method. Solutions of the compound at concentrations of 0, 50, 100, 150, 200 and 250µg/ ml were added to sterilized medium i...

...look at what happens. But what I really wanted to know from this email, was if there's a package or function for natrual selection simulation I could make use of, to see if I can simulate the experiment. I want to start with a distribution of concentration tolerance values, taken from the inhibitory concentration values from my first lot of microbes, back when term began. Draw 3000 from this. Then values in that draw that fall below the exposure concentration I did in my experiment, are removed, or have a high chance of being removed. Then, from what is left, a draw is made again - or perh...
