PEREZ, Helder Alfonso  and  LOPEZ CANOVAS, Cecilia. Distribución espacio-temporal de la meiofauna béntica en cuatro playas del Litoral Norte de la Habana. Rev. biol. trop [online]. 2006, vol.54, n.3, pp.985-995. ISSN 0034-7744.

Temporal spatial distribution of benthic meiofauna in four beaches of the northern Havana shore. The temporal-spatial distribution of benthic meiofauna was evaluated in four beaches at the north coast of Havana, Cuba, from March 2003 to February 2004. We studied two urban beaches (Santa Fe and La Concha) and two tourist beaches (Mar Azul and Canasí). Monthly meiofauna samplings were taken by scuba-diving using with a syringe (inner diameter 2.5 cm), and physico-chemical parameters (grain size, interstitial salinity and water column salinity were recorded with standard equipment). Statistical analysis (MDS and ANOSIM) were performed. Depth and biotope kind were the same in the four beaches. Highest densities were obtained in Santa Fe ( 7 133.48 ind/10 cm2) while the lowest mean densities were found in Canasí (892.12 ind/10 cm2). We recorded 13 taxa; the dominant organisms in Santa Fe and Mar Azul were free-living marine nematodes. Copepods were the dominant organisms in La Concha and Canasí. Rev. Biol. Trop. 54(3): 985-995. Epub 2006 Sept. 29.

Keywords : benthic meiofauna; tropical beaches; free-living marine nematodes; copepods; temporal-spatial distribution; Havana northern sub-littoral region.
