Alternative Title
System of scales for the classification and scoring of benthic and ichthyofaunal conditions in coral reefs of Cuba and the Wider Caribbean.
Abstract
Se propone un sistema de escalas de clasificación y puntaje de bioindicadores de de condición del bentos y de la ictiofauna de arrecifes coralinos de la metodología AGRRA (Atlantic and Gulf Rapid Reef Assessment), con algunos márgenes de variación más amplios que los aplicados en la Región del Arrecife Mesoamericano por otros autores. Por esa razón puede ser aplicable tanto en Cuba como en el Gran Caribe. Las escalas tienen cinco categorías de condición de los indicadores a los que corresponden puntajes del 1 al 5, respectivamente. La mayoría de los indicadores tiene en sus intervalos una progresión geométrica de base 2. En los restantes, la escala de intervalos se basó en el criterio de los autores. Las escalas se basaron en los abundantes datos de AGRRA disponibles de Cuba y del Gran Caribe. Esta propuesta es una herramienta complementaria o alternativa a la aplicación actual de promedios regionales de los indicadores AGRRA como valores de referencia de condición del bentos y de la ictiofauna en arrecifes coralinos. Tiene la ventaja de que a diferencia de los promedios regionales las escalas no varían con el tiempo.
A system of scales is proposed for the classification and scoring of bioindicators of AGRRA (Atlantic and Gulf Rapid Reef Assessment) methodology, for both benthic and ichthyofaunal conditions in coral reefs, with some wider variation limits than those applied by other authors in the Mesoamerican Reef Region. For that reason it can be applied in Cuba as well as in the wider Caribbean. The scales bear five condition categories consistent with scores of 1 to 5, respectively. Most indicators have a base-2 geometrical progression in their intervals. In the remaining indicators, the scales of intervals are based upon author’s criterion. Scales are based on the abundant AGRRA data available from Cuba and the Wider Caribbean. This proposal is a complementary or alternative tool to the current application of regional averages of AGRRA indicators, as reference values of benthic and ichtyofaunal conditions in coral reefs. The proposal has the advantage that, unlike regional averages, the scales do not vary in time.
