Cluster dendrogram of ostracod species in 100 m depth bands of the study area in the NW Pacific (i.e., 40° – 60°N, 120° – 180°E, 4,800–9,300 m depth). The numbers above each edge show the probability of nodes below that edge occurring as a cluster in resampled trees, via ordinary bootstrap resampling (BP, blue) or multiscale bootstrap resampling (AU, red).
