Spatial variation in the functional characteristics of herbivorous fish communities and the resilience of coral reefs

Many ecosystems face degradation unless factors that underpin their resilience can be effectively managed. In tropical reef ecosystems, grazing by herbivorous fishes prevent coral-macroalgal phase shifts commonly signal loss of resilience. However, knowledge characteristics most promote is typically experimental, localized, and sparse, which limits broad management applications. Applying sound ecological theory to broad-scale data may provide an alternative basis for ecosystem management. We explore the idea positively related diversity within among functional groups organisms. Specifically, we infer relative vulnerability different subregions Great Barrier Reef (GBR) based on local fish communities. slopes 92 reefs set in three zones continental shelf eight latitudinal sectors GBR were surveyed multiple occasions between 1995 2009. Spatial variation community structure was high driven primarily position. Measures diversity, redundancy, abundance generally higher offshore lower inshore. Two turbid inshore considered vulnerable very low measures herbivore function, this supported occurrence one subregions. Eleven resisted after major coral mortality included some with function. The fact did not necessarily occur when large herbivores scarce indicates other environmental compensated preserve Estimates solely function thus prove conservative, but caution appropriate, since compensatory are largely unknown could eroded unwittingly anthropogenic stresses. Our suggest managing threat successfully will require spatially explicit strategies consider both communities raise or thresholds. A strong positive correlation water clarity species richness suggests quality generic importance ensure services important group herbivores.

Different species size classes vary in their feeding ecology impact reef ecosystems distinct ways. We documented differences 9 Keys National Sanctuary (FKNMS). Many key be summarized by assigning groups (e.g. scrapers, excavators, croppers, macroalgae browsers), which differentially responsible for carrying out specific ecological processes. For example, we found Sparisoma viride, Scarus coelestinus, Sc. guacamaia, taeniopterus, vetula feed short turfs with few sediments, while Sp. aurofrenatum, chrysopterum, rubripinne longer sediment-laden addition macroalgae. Further, use types indicate contrasting impacts benthos. Species scrape excavate epilithic endolithic algae, tend tear or crop algae from reef. These behaviors result different rates removal, carbonate erosion, sediment production.
