Ecological studies on the littoral attaching micro-algae. III. Seasonal occurrences of epiphytic micro-algae on the natural seaweeds and artificial seagrasses in Ago Bay.

Abstract

Epiphytic communities on Sargassum piluriferum C. Agardh and artificial seagrasses were examined in Sargassum bed of Ago Bay every month during March 1981 and March 1982. Most of the epiphytes were diatoms, and their cell numbers were 106-107 cells/g dry weight of Sargassum and 103-106 cells/cm of artificial seagrass filament. The diversity of epiphytic flora on the Sargassum was greater than that on the artificial seagrass filament, and occurring species changed more frequently on the Sargassum than on the artificial seagrass filament. Main dominant epiphytes on Sargassum were algae which predominated' particularly in the early stage of epiphytic algal succession on the fresh substrate. The results obtained in the present study suggest that epiphytic flora on, Sargassum remain in the early stage of epiphytic algal succession throughout the year.

Ecological Studies of Epiphytic Microalgae and Epiphytic Zooplankton on Seaweeds of the Eastern Harbor, Alexandria, Egypt

“…In fact, these literatures focused on the epiphytic macroalgal species (Rindi and Guiry, 2004;Muñoz and Fotedar, 2009;Kersen et al, 2011), whereas very few literatures dealt with epiphytic microalgae and/or epifauna. Tanaka et al (1984) conducted a study on epiphytic microalgal communities on Sargassum piluriferum and artificial seagrasses in Sargassum bed. Totti et al (2009) conducted a survey on epiphytic diatom communities on ten species of seaweeds belonging to brown, red and green macroalgae from Iceland coastal waters.…”
