Variación espaciotemporal de algunos macroinvertebrados (Gastropoda, Bivalvia y Echinodermata) de fondos someros del Archipiélago Espíritu Santo, Baja California Sur, México FJ González-Medina OE Holguín-Quiñones G De la Cruz-Agüero Ciencias de la Tierra moluscos comunidad estructura equinodermos archipiélago Se realizaron cuatro muestreos (octubre de 2001 y enero, abril y junio de 2002), en nueve localidades alrededor delArchipiélago Espíritu Santo, Baja California Sur, México, con el objetivo de identificar patrones de variación espaciotemporalen la estructura de la comunidad de macroinvertebrados de fondos someros, preferentemente rocosos. La abundancia delmacrobentos conspicuo (gasterópodos, bivalvos y equinodermos) se estimó visualmente mediante buceo libre a una profundidadentre 4 y 6 m a lo largo de dos transectos en banda paralelos a la línea de costa. Cada transecto fue de 5 m de ancho y 50 m delargo, con una superficie total de 500 m2 por localidad. Asimismo, se registró la temperatura superficial del mar, la exposición aloleaje, la pendiente y el tipo de sustrato. Se identificaron 32 especies; el grupo mejor representado fue el de los equinodermoscon 18 especies de 13 familias, seguido de los moluscos con 14 especies de 13 familias. La especie con mayores abundanciamedia y densidad fue Tripneustes depressus (140.25 ± 64.21 ind y 0.28 ind m2, respectivamente). No se encontraron diferenciassignificativas en la diversidad, equidad y riqueza de especies entre los meses; sólo hubo diferencias entre las localidades (P <0.05). Se identificó un patrón espacial en el archipiélago con niveles bajos (0.4 bits ind1) de diversidad media en el litoralexpuesto y altos (2.0 bits ind1) en el semiprotegido. 2006 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48032104 es http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1A Vol.32
