Figure 4 in Temporal changes in burrow structure of the thalassinidean ghost shrimps Trypaea australiensis and Biffarius arenosus

Figure 4. Dendrogram showing how casts of Biffarius arenosus burrows cluster together based on overall morphological similarities (W denotes casts made in winter, P are casts made in spring, S are casts made in summer and A are casts made in autumn). The horizontal dashed line shows 80% similarity with two main groups of casts, each containing representatives of each season.
