In this third work concerning the marine algal flora of South-central Somalia. The species belonging to the Siphonocladales-Cladophorales complex are examined. The study of the material available, has led to the identification of 31 species. Most of them are recorded for the first time for the Somalian coast, due mainly to the only sporadic researc...
Article
The algal flora and his vertical distribution on the cliff near Gesira (central-southern Somalia) was analyzed along two adjacent transects, each exposed to different degree of wave action. Epiendolithic blue-green algae dominate the upper portion of the littoral fringe, especially Entophysalis deusta. A distinct belt of mainly red algae grew near...

In questo secondo contributo vengono prese in esame le specie appartenenti ai generi Halimeda e Udotea raccolte sulle coste centro-meridionali della Somalia. Per quanto riguarda il genere Halimeda l'esame del materiale disponibile ha portato all'identificazione di sette entità: H. cylindracea, H. discoidea, H. incrassata, H. macroloba, H. opuntia,...

Nell'ambito di un programma di ricerche sulla flora algale bentonica della Somalia centro-meridionale, si è presa in esame, in questo primo contributo, la consistenza numerica e la distribuzione del genere Caulerpa nelle diverse località visitate.Sulla base del materiale disponibile è stata elaborata una chiave analitica delle 15 entità identificat...
Article
The 69 species found in a recent study of the benthonic algae at Sar Uanle, South of Chisimaio, in southern Somalia are listed. Many species are reported for the first time for Somalia because there have been few studies of this region of the western Indian Ocean. A considerable number of the species found are widely distributed in the Indo-Malaysi...

Contribution to the study of the marine algae of Sar Uanle (Southern Somalia). – Some preliminary researches have been carried out on the algal flora of Sar Uanle, lying south of Chisimaio in southern Somalia. The material first collected for these researches, that includes 69 species, appears mainly new for the Somalia coasts. This is due to the f...

... Much of the information from coastal southern Somalia comes from studies which took place in 1970-1980(Pardi 1976a, b, 1977, Sartoni 1976, Messana et al. 1977, Vannini et al. 1977, Chelazzi and Ferrara 1978, Moggi 1987, sponsored by the 'Centro di Studio per la Faunistica ed Ecologia Tropicali' of the Consiglio Nazionale delle Ricerche (C.N.R.), Firenze. Additional information on the dune vegetation were provided by Pichi Sermolli (1957) and Friis and Vollesen (1989). ...
... It has been distinguished from the widespread C. linum (O. F. Mü ll.) Kü tz. by the crisp (stiff and wiry) filaments and thicker walls in contrast to the rather lax filaments and thinner walls in C. linum (Sartoni 1992, Littler and Littler 1997, Coppejans et al. 2009). Both species are reported to form clumps, often entangled with other algal species. ...
... However the tropical representatives of Cladophora remain largely unstudied. In the tropical Western Indian Ocean limited studies of the genus Cladophora are restricted to the publications of Sartoni (1986 Sartoni ( , 1992; Somalia), Jaasund (1976; Tanzania) and Børgesen (1940, 1946, 1948; Mauritius). Seven distribution groups of the genus Cladophora have been distinguished, based on the species' northern and southern boundaries in combination with winter and summer isotherms of the sea surface (van den Hoek 1979 Hoek , 1982 van den Hoek & Chihara 2000). ...
... The algal flora from tropical Western Indian Ocean reefs is relative well known (e.g. B0rgesen 1940-1957, Isaac 1967, Sartoni 1974, 1978, 1979, 1992, Jaasund 1968, Papenfuss et al. 1982, Kalugina-Gutnik et al. 1992, Ballesteros 1994. However, in spite of their importance, coralline algae from these reefs have received little attention and only recently Chamberlain (1993, 1994 a, b), Chamberlain (1993) and Chamberlain and Norris (1994a,b) have given detailed information on selected species occurring at Natal, South Africa. ...

... Strictly erect versus ascending growth forms are not considered to be major taxonomic differences in Ceramium (Dixon 1960, Womersley 1978. Ceramium cingulatum is unique among South African representatives of the genus in its unbranched erect axes.The species has been reported in the Indian Ocean from Somalia, Tanzania and the Seychelles (Jaasund 1970, Sartoni 1975,Wynne 1995. ...
