Table 1 Spearman’s rank correlation (ρ) coefficients for marine bivalve diversity contrasted with latitude. Data are for the eastern coastline of Australia, based either on field collections (“field”) or on subsets of OBIS (the full dataset containing records after 1980, OBIS inclusive of observational data, and a subset of OBIS that contains cells centered on field data). Diversity metrics shown are the S2/m equation of Alroy (2020), Simpson’s D (D), Shareholder Quorum Subsampling (SQS) and Fisher’s alpha. Asterisks show significant values (*p< 0.05, **p< 0.01).
