FIGURE 5 in Barcoding without DNA? Species identification using near infrared spectroscopy

FIGURE 5. Discriminant analysis of the entire spectrum in which each species has a unique symbol. A) Note that intraspecific variation is so small that the entire set of points per individual is encompassed by the one point for the species. B) Amplification of one point (one species, N. neoaustralis) illustrates the small intraspecific variation. DF (1, 2 and 3) indicate the discriminant functions.
