<h6>【 摘 要 】</h6>
<p style="text-align: justify; text-indent: 2em;">
Los ambientes béntico-marinos de Dominica, Antillas Menores, incluyen 1 814.7ha y cerca del 90% de la costa. Este es el primer trabajo sobre el tamaño y distribución de los ambientes costeros sublitorales y sus comunidades epibénticas. Los pastos marinos constituyeron el ambiente más extenso, con 265ha. Los arrecifes coralinos presentaron una cobertura de 72.2ha. Ambos tipos de ambientes se encontraron principalmente en la costa oeste y norte, regiones con la mayor diversidad de ambientes marinos. Las áreas rocosas (911.5ha) dominaron las costas este y sur de la isla, y junto con las áreas arenosas (566ha) constituyeron el 81% de los ambientes bénticos. La distribución de pastos marinos, que incluyeron cuatro especies nativas y una invasiva, no se pudo corroborar con los pocos informes previos. La cobertura béntica de los arrecifes coralinos de Dominica fue mucho menor que las 7 000ha que se habían reportado previamente. Estas discrepancias ilustran la ventaja de los estudios ambientales basados en trabajo de campo y la compilación sistemática de datos ambientales, especialmente en casos como Dominica donde por lo angosto de la plataforma insular, los ambientes marinos sublitorales quedan muy cerca de los centros urbanos. Se demuestra que técnicas simples pueden ser utilizadas a gran escala alrededor de una isla para realizar inventarios de los recursos marino-costeros, mediante mapas y repositorios públicos de datos para usos futuros, que permiten el desarrollo de medidas de conservación efectivas.<br>Surveys of benthic marine habitats encompassing 1 814.7ha and lining 90% of Dominica’s shoreline were carried out to build the first composite picture of the distribution and size of the island’s near-shore sublittoral habitats, and the epibenthic communities they harbor. Field survey sites covered areas ranging from 1 425 to 29.6ha, lining the shore in bands ranging between 50 and 250m in width, in waters no deeper than 30m. Thus a total of 755ha of benthos were surveyed in October and November of 2007. The benthic habitat composition of an additional 1 059.7ha was inferred with the help of unpublished data and satellite imagery. Seagrass beds were the most widespread organism-built habitat type with 265ha. Coral reefs covered 72.2ha. Both of these habitats were predominantly established along the West and North coasts, which included the island’s most habitatdiverse regions. Rocky environments (911.5ha) dominated the East and South coast and together with sandy areas (566ha) constituted 81% of the island’s marine benthos. It is apparent that seagrass beds, which include four native and one invasive seagrass species, had not been surveyed as previous distribution reports could not be confirmed. Similarly, the benthic cover of Dominica’s coral reefs is evidently far below the previously reported 7 000ha. Such discrepancies highlight the advantage of environmental assessments based on field surveys and systematic data compilation, particularly in cases like Dominica where a narrow island shelf stages marginal marine resources in spatial proximity to each other and human settlements. This study has demonstrated how low-tech field methods can be applied on an island-wide scale to build an inventory of marine resources in the form of habitat maps and data repositories publicly accessible for future use. In the absence of such efforts, the development of conservation measures and status reports will remain ill founded. Rev. Biol. Trop. 58 (2): 589- 602. Epub 2010 June 02.</p>
