¹H-NMR profiles of <i>Porites compressa</i> are reproducible within and between coral colonies.

Abstract

<p>(A) PCA comparing <i>Porites compressa</i>¹H-NMR metabolite profiles between technical, intra-colony and inter-colony samples. Profiles from inter-colony <i>P. compressa</i> samples were obtained using two extraction methods: method 1 and method 2 (B) Boxplots of percent relative standard deviation (% RSD) scores across ¹H-NMR variables comparing technical, intra- and inter-colony variability. The median is indicated (black bar) along with the quartile ranges and outlying values (open circles). Letters denote Kruskal-Wallis test results (p<0.001). Groups connected by the same letter are not significantly different.</p
