SUMMARY: The first comprehensive study of the marine algal flora of Namibia including descriptions and illustrations of most species is presented. The main objective of this work is to report a flora that, until now, has scarcely been studied. The work compiles all the available information on the marine benthic flora of Namibia and provides new data about it composition and biogeography, as well as detailed descriptions and remarks of most of its species. The samples on which this study is based were collected between 1986 and 1989 in the eulittoral and the upper sublittoral zones of the north half of the Namibian coast. According to the present data, the marine benthic flora of Namibia comprises 196 taxa (147 Rhodophyceae, 20 Phaeophyceae, 15 Ulvophyceae, 6 Cladophorophyceae and 8 Bryopsidophyceae), 21 of which has not been recorded from this coasts. This temperate flora is mainly characterized by a low number of species, a low proportion of Phaeophyceae and a high degree of endemism. Concerning the species number, the flora is quite poor due to both the scarce availability of colonizable substratum and the low diversity of habitats. On the other hand, the low proportion of Phaeophyceae is the reason for which the R/P and (R+C)/P ratios take disproportionately high values and so they are not useful in this geographical area. As regards the degree of endemism, the marine benthic flora of Namibia includes quite a high number of taxa endemic to southern Africa (55 taxa; 28.1% of the flora); 25 of these 55 taxa (12.8% of the flora) are endemic to the biogeographic Benguela Marine Province and only Acrosorium cincinnatum is endemic to the Namibian coasts.Key words: Namibia, marine algae, morphology and anatomy, distribution, biogeography, taxonomy, check-list. RESUMEN: ALGAS BENTÓNICAS MARINAS DE NAMIBIA. -Este trabajo recoge toda la información existente hasta el momento sobre la flora bentónica marina de Namibia y proporciona nuevos datos sobre su composición y biogeografía, además de descripciones detalladas y valoraciones críticas de muchas de sus especies. El trabajo se ha realizado a partir de muestras florísticas recolectadas entre los años 1986 y 1989 en las zonas eulitoral y sublitoral superior de la costa de la mitad norte del país, entre Walvis Bay y la desembocadura del río Kunene. Según los datos actuales, la flora bentónica marina de Namibia está representada por 196 táxones (147 Rhodophyceae, 20 Phaeophyceae, 15 Ulvophyceae, 6 Cladophorophyceae y 8 Bryopsidophyceae), 21 de los cuales no habían sido citados hasta el momento de las costas de este país. Se trata de una flora de carácter templado que se caracteriza principalmente por el bajo número de especies, la escasa proporción de feofíceas y el elevado grado de endemismo. En cuanto al número de especies, la flora de Namibia es relativamente pobre, debido a la escasa disponibilidad de substrato colonizable y a la baja diversidad de hábitats. Por otra parte, la baja proporción de feofí-ceas hace que los índices R/P y (R+C)/P adopten valores desproporc...

“…2 As rodofíceas foram analisadas ainda quanto a batimetria, período de coleta e a ocorrência entre as estações. Para análise comparativa do número de rodofíceas entre as ilhas oceânicas comparou-se os táxons citados para o Arquipélago de Fernando de Noronha por Dickie (1875), Hemsley (1885), Murray (1891), Williams & Blomquist (1947), Széchy et al (1987;1989), Pedrini et al (1992), Pereira et al (1996), Pereira et al (2002), Pereira (2006); para Trindade e Martin Vaz por Richardson (1975), Joly (1950;1953), Pedrini et al (1989) Ugadim (1974;1976), Barbosa et al (2003), Fujii & Villaça (2003) e Villaça et al (2006).…”

Este trabalho apresenta o levantamento florístico e alguns aspectos ecológicos das algas vermelhas do Arquipélago de São Pedro e São Paulo (00º56'N; 29º22'W - 00º 55'N; 29º 20'W). O material foi coletado durante as marés baixas em seis estações, nas zonas entre-marés e infralitoral no mês de outubro de 2003 (estação seca) e abril de 2005 (estação chuvosa). Foram registradas 24 espécies, distribuídas entre as ordens Bonnemaisoniales (uma espécie), Ceramiales (12 espécies), Corallinales (seis espécies), Erythropeltidales (uma espécie), Gelidiales (uma espécie), Rhodymeniales (duas espécies) e Stylonematales (uma espécie). Foram feitos 15 novos registros de rodofíceas à flora do Arquipélago e quatro novas adições para as ilhas oceânicas brasileiras: Ceramium brevizonatum var. caraibicum H. E. Petersen & Börgesen, Ceramium tenerrimum (G. Martens) Okamura, Jania prolifera A. B. Joly e Stylonema alsidii (Zanardini) K. M. Drew. Foram registradas algas vermelhas em apenas três estações. A maior riqueza de táxons (16 taxa) ocorreu na Estação 01 (Enseada) e no período chuvoso (23 taxa). A similaridade florística, com base no índice de Sørensen, em relação à profundidade, variou de 0 a 0.66%.

The seaweeds resources were sampled from exposed shore of Nathia Gali beach, Karachi coast at low tide. The present data of diversity and biomass of seaweeds provide a comparison of two different periods i.e., from 1989 to 1991 and 2012. A total of 60 taxa were recorded in the coastal area of Nathia Gali; 14 belonging to chlorophyta, 15 to Phaeophyta and 31 to Rhodophyta. The green seaweeds viz, Caulerpa racemosa, Codium iyengarii and Halimeda tuna; brown seaweeds, Cystoseira indica, Iyengaria stellata Padina pavonica and Sargassum boveanum and red seaweeds Gracilaria corticata and Scinaia fascicularis were found to be the dominant species of Nathia Gali. The total biomass 66056.18 g. m -2 was recorded during the study period and the highest biomass was recorded in January (16551.79 g m -2 ) and the lowest in July (1276.3 g. m -2 ). In winters, seaweeds biomass and growth increased due to low temperature of air and seawater with low intensity of light and high dissolved nutrients. The richness of seaweed resources in the studied area is due to the intertidal rocks available on the coast but nowadays, there is lot of disturbance due to anthropogenic activities such as discharge of domestic and industrial waste; tanneries effluents; rainfall and associated pollutant from runoff; shipping and agricultural sources. These disturbances play vital role in changing the ecosystem which effects flora and fauna of the coast.
