Reply to ‘Dissimilarity measures affected by richness differences yield biased delimitations of biogeographic realms’

Abstract Recently, we classified the oceans into 30 biogeographic realms based on species’ endemicity. Castro-Insua et al. criticize the choices of dissimilarity coefficients and clustering approaches used in our paper, and reanalyse the data using alternative techniques. Here, we explain how the ap...
