Stability and characteristics of spatial description parameters for nematode populations

The parameters of Taylor's Power Law (s(2) = am(b)) relating variance (s(2)) to mean population level (m) were acceptably stable in different fields with similar cropping systems. Values of both a and b parameters varied with nematode species. The value of a was a function of sample size (numbe...
