Description:Long-term monitoring data at the biogeographic scale are essential for developing baselines of biodiversity patterns and tools to diagnose natural cycles, trends, and anomalous events to assess threats from climate change. However, studies using these data often limit their analyses to relatively few metrics that may not adequately capture the breadth of biodiversity. Here, we calculate a suite of compositional and functional biodiversity metrics—collectively comprising ecoscapes—to better resolve assemblage-level responses to environmental variability and test the spatiotemporal lability of faunal biogeographic provinces. Methods: Species composition and abundance data from two long-term fisheries-independent surveys were collated with a functional trait database for pelagic taxa. Distinct assemblages were identified through cluster analysis. Compositional and functional alpha- and beta-level biodiversity metrics were then calculated to characterise assemblage-level biodiversity and to identify patterns of regional community composition and turnover in space and time.
