dc.description.abstractThis work presents the most complete an updated taxonomic list of the shallow water (0-100m) Echinodermata (Crinoidea, Asteroidea, Ophiuroidea, Echinoidea, and Holothuroidea) from Puerto Rico. The species list is a review based on the collection of echinoderms of the National Museum of Natural History (NMNH) at Washington, D.C., the Marine Invertebrate collection of the Department of Marine Science (MSC), University of Puerto Ric o, Mayaguez Campus, and from simultaneous colections in 8 coral reefs stations (Buoy, Weimberg, San Cristobal, Enrique, Media Luna, Turrumote, Pelotas and Romero) and 6 sampling stations in sea grass beds (Caballo Blanco, Enrique, San Cristobal, Laurel, La Corona del Medio de Laurel and Media Luna) at La Parguera, Puerto Rico , during 2005 and 2006. A total of 108 species were revised (6 crinoids, 14 asteroids, 44 ophiuroids, 15 echinoids, and 29 holothuroids) representing 5 classes, 15 orders, 1 suborder, 33 families, 3 subfamilies and 68 genera. Nine species, Davidaster discoidea, Poraniella echinulata, Ophioderma squamosissimum, Ophioderma phoenium, Ophionephthys limicola, Plagiobrissus grandis, Actinopyga agassizi, Holothuria (Halodeima) floridana, and Synaptula hydriformis are new records for Puerto Rico. The exact locations of 52 species are stated for the first time. Of the species found (108), 74 were preserved at the MSC, 61 at the NMNH, while 39 were recently collected from the coral reefs and sea gr ass beds at La Parguera. In the sea grass beds, the total mean abundance of echinoderm species was 18.46 ind.m-2; ophiuroids and echinoids had the highest abundance (0.31-3.99 ind.m-2 and 0.22- 5.89 ind.m-2, respectively). The spatial patterns of total echinoderm abundance in these communities were characterized by a significant difference between sampling stations, being San Cristobal the main station introducing these differences .en_US
dc.description.abstractEste trabajo presenta la lista taxonómica más completa y actualizada del Filo Echinodermata (Crinoidea, Asteroidea, Ophiuroidea, Echinoidea y Holothuroidea) de aguas someras (0-100 m) de Puerto Rico. La lista de especies es una revisión basada en la colección de equinodermos del National Museum of Natural History (NMNH), Washington, D.C., la colección de Invertebrados Marinos del Departamento de Ciencias Marinas (MSC), Universidad de Puerto Rico, Recinto Universitario de Mayagüez y de una colecta simultánea realizada en 8 estaciones en arrecifes coralinos (Buoy, Weimberg, San Cristobal, Enrique, Media Luna, Turrumote, Pelotas y Romero) y 6 estaciones en praderas de pastos marinos (Caballo Blanco, Enrique, San Cristobal, Laurel, La Corona del Medio de Laurel y Media Luna) en la Parguera, Puerto Rico, durante el 2005 y el 20 06. Se registraron un total de 108 especies (6 crinoideos, 14 asteroideos, 44 ofiuroideos, 15 equinoideos y 29 holothuroideos) representando 5 clases, 15 órdenes, 1 suborden, 33 familias y 68 géneros. Nueve especies, Davidaster discoidea, Poraniella echinulata, Ophioderma squamosissimum, Ophioderma phoenium, Ophionephthys limicola, Plagiobrissus grandis, Actinopyga agassizi, Holothuria (Halodeima) floridana, and Synaptula hydriformis son nuevos registros para Puerto Rico. La localidad exacta de 52 especies se registra por primera vez. De las 108 especies encontradas, 74 están depositadas en la MSC, 61 en el NMNH y 39 fueron colectadas de los arrecifes de coral y las praderas de pastos marinos de las estaciones escogidas en La Parguera. En las praderas de pas tos marinos, la abundacia total promedio de equinodermos fue de 18.46 ind.m-2; ofiuroideos y equinoideos tuvieron la abundancia más alta (0.31-3.99 ind.m-2 y 0.22- 5.89 ind.m-2, respectivamente). El patrón espacial de la abundancia total de equinodermos en estas comunidades se caracterizó por presentar diferencias significativas entre estaciones, siendo San Cristóbal la estación principal que introdujo estas diferencias.en_US
