dc.description.abstractShelf edge reefs provide valuable habitat to a wide variety of marine organisms. Yet, because of their depth and highly sloping bottom these areas are not understood with respect to fish habitat relationships and even the way these environments can be characterized and mapped. In order to investigate the relationship between habitat complexity and fish utilization, this study has concentrated on the factors affecting Scaridae abundance at the shelf edge off of La Parguera, Puerto Rico. For remotely sensed data sets as well as in situ measurements, rugosity was classified using new techniques, developed for this study, that minimize bias associated with the slope of the substratum. An empirical orthogonal function analysis showed that parrotfish abundance on the shelf was associated primarily with structural variables. The results obtained from this study provide a novel approach to data interpretation that can be used in determining critical habitat to sensitive fish species.en_US
dc.description.abstractLos arrecifes del veril proporcionan un hábitat valioso a una gran variedad de peces y otros organismos. Por la profundidad e inclinación del arrecife, estos arrecifes son entendidos mal con respecto a pez utilización y son difíciles para cuantificar. Para investigar la relación entre la complejidad del hábitat y la utilización del hábitat de peces, este estudio se ha concentrado en el efecto que la rugosidad tiene en la abundancia de los Scaridae en La Parguera, Puerto Rico. La rugosidad y la complejidad del hábitat se han clasificado usando nuevas técnicas que reducen el sesgo en los datos geográficos asociados a la pendiente del substrato al mínimo. Un análisis de función ortogonal empírico demostró que la abundancia de peces loros en el estante estaba asociado sobre todo a variables estructurales en el ambiente del arrecife. Los resultados obtenidos de este estudio proporcionan un acercamiento nuevo a la interpretación de datos que pueden ser utilizados en la determinación de hábitats críticos de especies sensibles de peces.en_US
