To illustrate the application of our maximally nonmetric MDS to nonmetric data, we analyze the DNA sequence for the NADH subunit 2 of cichlids in Lake Tanganyika and Lake Malawi [9]. The original dataset consists of nucleotide sequences of length = 1044 for 31 species (see the caption of Fig. 2 for the list).

Figure 12. Plots of TOC versus TN for core F from Lake Albert (Beuning et al 1997) and core M98-2P from Lake Malawi. In both cases the regression lines intercept the TN axis at a positive value, implying that some of the nitrogen is present in a form not a.ssociated with organic carbon. This is commonly referred to as inorganically hound nitrogen. The value of the N intercept (arrows) can be u,sed to correct the C/N such that it reflects only the organic component of the sediment.
