Abstract
espanolSe realizo una investigacion de campo de las comunidades de playas arenosas en 10 sitios al norte y sur del Estado de Quintana Roo, Mexico, en 2011. Para cada playa se realizaron 3 transectos perpendiculares a la costa con un numero variable de niveles dependiendo de la longitud de la playa. Las pendientes de las playas fueron tambien variables; sin embargo, como patron recurrente, la parte sur de cada playa fue mas extensa que la parte norte. La fauna mejor representada fue la de los moluscos (18 especies), aunque tambien se registraron otros grupos como: crustaceos (4), anelidos (4), sipunculidos (1), nemertinos (1), foraminiferos (4) e insectos (1). Los analisis numericos dividieron el litoral de la costa en sitios de la Rivera Maya que tuvieron mayor riqueza y diversidad de la fauna y en sitios de ubicados en la Gran Costa Maya que fueron los menos diversos. El ensamblaje que formaron los sitios a partir de los grupos principales muestran afinidades entre sitios cercanos, pero tambien permitio detectar diferencias entre zonas en una misma region. Utilizando un analisis divisivo del contenido de informacion de segundo orden, para los diferentes grupos, se obtuvo las especies responsables de la mayor caida de informacion; en los moluscos, fue Terebra tuberculosa, mientras que para los anelidos fue Scoloplos latum y para los foraminiferos Bigenerina angulata. Se propone un estudio a mayor plazo para este ecosistema. EnglishField research of macrofaunal communities of sandy beaches at 10 sites of the central and southern coast of Quintana Roo State, was performed in 2011.
