The authors of this study looked at how reef fish community assemblages have changed over time at several sites in Florida. In particular, they looked for evidence of biological homogenization (increasing species similarity between sites), which can alter the ecological function of systems as well as the economic value associated with ecosystems through complex socio-ecological dynamics. The authors used REEF survey data to measure biological homogenization by tracking taxonomic changes over a decade across 13 near-shore sites off the Atlantic coast of Florida. Sites that were closer to populated coastlines, or have been subject to substantial disturbance events, were more likely to show homogenization. Protected reef sites showed little evidence of homogenization. The authors postulated feedback mechanisms between societal values, diver practices, diver experience, and the severity of homogenization. The authors also discuss how baseline knowledge of the ecosystem could influence whether or not people are inspired to take action when baseline community structures change.
