Se realizó un estudio sobre el patrón de distribución de macroalgas en un canal de corrientes en Playa Las Cuatas, Guerrero, México. Se determinaron 28 especies: 3 Chlorophyta, 9 Phaeophyta y 16 Rhodophyta. La estructura comunitaria está caracterizada por una aparente distribución en bandas definida por las especies dominantes. Una franja rosada de la coralina costrosa Lithophyllum decipiens se extiende del submareal superior hasta el intermareal medio. La feofita foliosa Sargassum liebmannii forma parches más o menos continuos en el intermareal inferior y medio. La extensión horizontal de esta especie es variable. Los niveles por arriba de L. decipiens están cubiertos por una banda extensa de feofitas costrosas. Parte del intermareal superior, medio e inferior lo ocupa Ralfsia hancockii. Mezclada con esta especie en su límite superior y extendiéndose por la zona supramareal se encuentra R. confusa. Otras especies tienen una distribución variable entremezclándose en diferentes bandas. Este patrón de distribución de especies se analiza a la luz de varias propuestas de zonación.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Current channels are one of the recognized intertidal rocky habitats of the Mexican tropical Pacific. A study on the distributional pattern of macroalgae was made in a current channel in Playa Las Cuatas, Guerrero, Mexico. Twenty eight species were determined: 3 Chlorophyta, 9 Phaeophyta and 16 Rhodophyta. The communitary structure is characterized by an apparent banded distribution defined by the dominant species. A pinkish belt of the crustous coralline Lithophyllum decipiens is extended from the upper subtidal to the middle intertidal. The folióse phaeophyta Sargassum liebmannii forms more or less continuous patches in the low at middle intertidal. The horizontal extension of this species is variable. Levels over L. decipiens are covered by an extense band of crustous phaeophytes. Part of the high, middle, low intertidal and up to the upper subtidal are occupied by Ralfsia hancockii. Mixed with this species in their superior limit and extending all over the supratidal is found R. confusa. Many other species are found with a variable distribution intermingling in different bands. This pattern of species distribution is analyzed in the light of several zonation proposals.]]></p></abstract>
