Resumen
El presente trabajo es el resultado del análisis de muestras de macroalgas en la Peninsula de Santa Elena (Ecuador) en 3 estaciones del área rocosa en la zona intermareal que corresponde a las playa de Salinas (Base Naval de Salinas), La Libertad (Puerto Pesquero) y Ballenita (Balneario), las cuales fueron colectadas mediante la técnica propuesta por Dawes (1991), utilizando una combinación de transepto lineal y del cuadrante, realizado para octubre y noviembre del 2009. Se aplico la estadística de Shannon-Weaver para diversidad y Bray Curtis para Similaridad.
Se identificaron una total de 21 especies de algas marinas bénticas, de las cuales 9 corresponde a la División Chlorophyta, 8 especies a Rodophyta y 4 especies a Heterocontonphytas. Las Chlorophytas son las mejor representadas con 9 especies. Se obtuvo su mayor abundancia en la zona de La Libertad, en cambio las Heterocontonphytas su mayor abundancia predomino en la Zona de Ballenita, para la zona de Salinas se mantuvo una abundancia media baja.
En cuanto a la diversidad de especies obtenida, se determinó que fue mayor para la playa de Salinasd con (H’ 2.68), seguida de La Libertad co (H’ 2.51) y Ballenita con (H’ 2.42).
Y la Similaridad entre las Playas muestreadas indica que Salinas y Ballenita tienen una Similaridad de 55% aproximadamente, mientras que La Libertad presenta Similaridad con las otras dos estaciones en un 52%.
This work is the result of the analysis of samples of macroalgae in the Peninsula de Santa Elena (Ecuador) on 3 stations in the area rocky intertidal zone corresponding to the Beach Salinas (Salinas Naval Base), La Libertad (Fishing Port ) and Ballenita (Spa), which were collected by the technique proposed by Dawes (1991), using a combination of linear and quadrant transept, conducted in October and November 2009. Statistic was applied to Shannon-Weaver diversity and Bray Curtis similarity We identified a total of 21 species of marine benthic algae, 9 of which corresponds to the Division Chlorophyta, 8 species and 4 species Rodophyta Heterocontonphytas. The Chlorophytas are the best represented with 9 species. was obtained for the most abundant in the area of La Libertad, however the most abundant Heterocontonphytas predominance in Ballenita Area, Salinas area for a mean abundance remained low. As for the diversity of species obtained, was determined to be greater for Salinasd beach with (H '2.68), followed by La Libertad co (H' 2.51) and Ballenita with (H '2.42). And the similarity between the beaches sampled indicates Ballenita Salinas and have a similarity of 55%, while that freedom has similarity with the other two stations by 52%.
