AB  - Functional trait-based approaches provide an opportunity to assess how changes in 
      habitat affect the structure of associated communities. Global analyses have 
      found a similarity in the composition of reef fish functional traits despite 
      differences in species richness, environmental regimes, and habitat components. 
      These large-scale patterns raised the question of whether this same stability can 
      be observed at smaller spatial scales. Here, we compared the fish trait 
      composition and their functional diversity in two Caribbean shallow coral reefs 
      with contrasting levels of habitat degradation: Limones (>30% cover), constituted 
      mainly by colonies of Acropora palmata and Bonanza, a reef with extensive areas 
      of dead Acropora structures, dominated by algae. To characterize the functional 
      structure of fishes on each reef, we calculated the community-weighted mean trait 
      values (CWM), functional richness, functional evenness, functional dispersion, 
      and functional originality. Despite the differences in habitat quality, reefs 
      exhibited a similar proportion and common structure on fish functional traits. 
      Functional richness and functional evenness differed significantly, but 
      functional dispersion and functional originality did not show differences between 
      reefs. The greater niche complexity driven by the high availability of 
      microhabitats provided by A. palmata may explain the higher functional richness 
      in Limones, whereas the reef degradation in Bonanza may contribute to a higher 
      functional evenness because of a similar distribution of abundance per fish trait 
      combinations. Our results suggest that widespread degradation on Caribbean reefs 
      has limited the type, variety, and range of traits, which could lead to a 
      functional homogenization of fish communities even at local scales.
