Analysis 1 : Explanation note: A. STRUCTURE bar plots with the highest likelihood for K = 5, 6, and 8 respectively. Instability was consistently noted across iterations at all values of K. B. An MDS plot demonstrates distinctness in TL-ro in three dimensions and TL-su in two dimensions. Calculations for optimal K were ambiguous and inconsistent, as were clustering patterns with regard to the B. constancei clusters (TL-co, PLSI-co and CD-co), particularly with regard to TL-co. MDS plots do not represent analyses, but are a visual interpretation of the dataset. TL-su and TL-ro are the most distinct and coherent clusters based on allele sharing distance.
