Conceptacle banding of <i>Porolithon onkodes</i> under UV light;

<p><b>a.</b> Cross-section of <i>P</i>. <i>onkodes</i> under UV light (BX50 Olympus microscope), arrows point to bands of conceptacles in skeleton made up of two or more conceptacles rows on top of each other; <b>b.</b> Cross-section of <i>P</i>. <i>onkodes</i> under UV light, horizontal arrow point to conceptacles, vertical arrow points to stain mark indicating the start of the summer season.</p

<i>Porolithon onkodes</i> density and conceptacle banding.

<p>Three images of the same <i>P</i>. <i>onkodes</i> sample (PK) showing relationship between conceptacle and density banding, arrows indicate areas of a) high density banding (dark areas) in 2D micro-CT image; b) conceptacle banding in UV image; c) high density banding (in light areas) in 3D micro-CT image.</p

<i>Porolithon onkodes</i> conceptacle banding.

<p>UV image of <i>Porolithon onkodes</i> (NV) showing four bands of conceptacles (represented by the four horizontal bands of white dots) indicating age and growth rate of the sample. The growing edge is located at the top of the sample.</p

QEMSCAN of <i>Porolithon onkodes</i>.

<p>Mineralogical mapping using Quantitative Evaluation of Minerals by Scanning electron microscopy (QEMSCAN) showing four bands (labelled on right side of image) of dominant mineral changes in <i>P</i>. <i>onkodes</i> from Heron Island, Great Barrier Reef. Conceptacles are indicated by arrows. Black lines indicate changes in dominant mineral.</p
