Here, we examine the diversity-stability relationship in a 27-year coral reef fish time series at 39 reefs spanning 10 degrees latitude on Australia\u2019s Great Barrier Reef. We find that an apparent relationship between species richness and synchrony of population fluctuations is driven by these two variables\u2019 covariation with proximity to coastal influences. Additionally, coral cover volatility destabilizes fish assemblages by increasing average population variability but not synchrony, an effect mediated by changes in the intensity of density regulation in the fish community. Our findings indicate that these two environmental factors, both of which are strongly influenced by anthropogenic activity, impact community stability more than diversity does, but by distinct pathways reflecting different underlying community-dynamic processes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tsai, C.H.and S.
