Se evaluó el valor explicativo de cuatro hipótesis en la variación geográfica de la riqueza total de especies y la riqueza de especies por familia en comunidades de corales y peces en el Sector Norte del Sistema Arrecifal Mesoamericano (NS-MBRS). Las cuatro hipótesis ponderan diferentes atributos de paisaje que son importantes para las especies de corales y peces: área de arrecife (RA), cobertura de coral vivo (LCC), complejidad de hábitat (HC), y riqueza de coral para los peces y los corales mismos. Tanto para las comunidades de coral como para las de peces, se estimó el número total de especies y el número de especies por familia en 11 arrecifes coralinos a lo largo de una sección de 400 km del NS-MBRS. La cobertura de corales duros y HC fueron cuantificadas usando videotransectos de línea y cadena, respectivamente; RA se estimó usando imágenes de satélite TM Landsat y un sistema de información geográfica. Se utilizó el análisis de regresion múltiple y el análisis de redundancia canónica para estudiar las relaciones de las especies de coral y de peces con las variables estudiadas. Los tres atributos de paisaje (RA, LCC y HC) en combinación fueron variables explicativas mucho más importantes para los patrones biogeográficos observados de la biodiversidad de peces y corales que la explicación individual de cada una de las variables. La riqueza de especies de coral y de peces estuvieron también fuertemente correlacionadas. Los indicadores de la diversidad funcional (grupos tróficos de peces y los grupos morfofuncionales de corales) siguieron los mismos patrones biogeográficos que la riqueza de especies. Los atributos de paisaje (RA, LCC y HC) mostraron ser excelentes indicadores de valores críticos de biodiversidad coralina. Esto significa que los simples atributos de paisaje pueden ser usados para predecir valores de biodiversidad más complejos en diferentes áreas de arrecifes coralinos. Tales predicciones pueden proporcionar una guía inestimable para las evaluaciones de biodiversidad regional, la extrapolación de estos resultados a áreas no muestreadas y una guía para la ecoregionalización dentro de grandes extensiones de áreas de arrecifes coralinos donde los datos son escasos. |
