Radial distribution of water content normalized by (A) dry weight (DW) and (B) wet weight (WW). Radial distribution of sulfated GAG content normalized by (C) dry weight and (D) wet weight. Circles indicate individual data and red dashes indicate median values for each layer. NP and AF biochemical properties were compared using a Mann‐Whitney U test on pooled data from Layers 1‐4 (NP) and Layers 7‐10 (AF; * represents P < .05). Differences in biochemical composition within each region (ie, shaded areas) were assessed using a Mann‐Whitney U test with Bonferroni correction. Layers that do not share the same letter are significantly different (P < .05)
