Patterns in the chaos: scale and the spatio-temporal dynamics of GBR reef fish assemblages

This paper analyses the spatial patterns and temporal dynamics of the long-term fish dataset from the LTMP (see LTMP metadata for details on methods).The dataset spand 233 coral reef fish species, recorded from 1995 to 2023 across the entire GBR.We analysed spatial patterns and temporal dynamics at the whole GBR scale and the sector x shelf scale, by year and decade, and by total density and species richness, family level and species level. We used Bayesian glmms, and multivariate techniques such as PCA, Adonis and RDA.
