The Line Intercept Method for Studying Plant Cuticles from Rumen and Fecal Samples
Preview not available

Abstract

Several methods are available for estimating the proportion, by area, of leaf cuticles of a given species in a rumen or fecal sample. They all involve choosing a line transect on a microscope slide and noting the cuticles that intercept the line. In this paper estimates based on lengths or squared lengths of intercept are compared. When there are several transects a jackknife method of combining the data is recommended. Simulation experiments indicate that this method provides satisfactory estimates, as far as bias and precision are concerned.
