dc.description.abstractCoral reefs are amongst the most biologically diverse habitats on earth, which, in addition to their ecological importance, are significant sources of sea food, nursery grounds for many fisheries and a reservoir of biochemicals for use as medicines (Bryant et al., 1998). They also play a major role in coastal protection and are the basis of many economically important tourist industries. The extraordinary productivity of coral reef ecosystems is itself a reflection of the photosynthetic contributions of the corals’ endodermal symbiotic microalgae (zooxanthellae) to the host for growth and reproduction (Muscatine, 1990). Any novel contaminant that inhibits symbiont photosynthesis could undermine one of the cornerstones of these biologically and economically important marine habitats with serious consequences. The potential ecological effect of Irgarol 1051® and other “booster biocide” compounds, in freshwater and marine environments, has not yet been studied in great detail. Comparative data for such compounds in marine systems are needed to clarify the contribution of antifoulant use to environmental concentrations and distributions. Without these data it is difficult to confidently evaluate environmental risk. Clearly, additional research is required to further investigate distribution of these compounds and their potential effects on the corals. Our work provides important new data, which unequivocally establish Irgarol 1051® distributions in marine systems outside temperate coastal regions. This study incorporates chemical assays to identify patterns of contamination in the Northeastern Caribbean, providing the basis for ecological risk assessment for resource managers.en_US
dc.description.abstractLos arrecifes de coral son uno de los hábitats más biologicamente diversos en el planeta. Además de su importancia ecológica, son una gran fuente de mariscos para consumo humano, vivero para peces y una reserva de bioquimicos para uso en medicamentos (Bryant et al. 1998). Estos también juegan un rol importante en la protección a las costas y son la base para muchas industrias turísticas. La extraordinaria productividad del ecosistema del arrecife de coral es a su vez un refiejo de la contribución por fotosíntesis de las microalgas endodermales simbióticas (zooxantelas) al favorecer el crecimiento y reproducción de los corales (Muscatine, 1990). Cualquier contaminante que inhiba la fotosíntesis del simbionte puede destruir la base de estos hábitats marinos que son biológicamente y económicamente importantes, lo que trae serias consecuencias. No se ha estudiado en gran detalle el efecto ecológico de Irgarol 1051® y otros compuestos biocida-estimulates en agua dulce y en ambientes marinos. Se requieren datos comparativos para aclarar la contribución del uso de antifoulants con las concentraciones ambientales y distribución de estos compuestos en sistemas marinos. Sin estos datos es difícil evaluar con seguridad el riesgo al ambiente. Claramente, se requiere investigar más profundamente la distribución de estos compuestos y su posible efecto en los corales. Nuestro trabajo provee impotantes datos nuevos para establecer sin lugar a duda la distribución de Irgarol 1051® en sistemas marinos fuera de las regiones costeras de latitudes templadas. Este estudio incorpora ensayos químicos para identificar los patrones de contaminación en el Caribe Noreste, proveyendo una base para los manejadores de recursos evaluar el riesgo ecológico.en_US
