“…Similarly to what was found in previous studies in the northeastern Brazilian coast, Ochrophyta were the most abundant macroalgae in the TSB (Coutinho et al 1993, Amado Filho et al 1997a, Villaça & Pitombo 1997, Muñoz & Pereira 1998, Figueiredo 2000, Costa Jr. et al 2002, Villaça 2002, Paula et al, 2003.…”

“…This is one of the most commonly found calcified algae found in coral reefs of the Brazilian northeastern coast (Leão 1982, Carvalho 1983, Martins et al 1991, Coutinho et al 1993, Villaça & Pitombo 1997, Costa Jr. et al 2002, besides being one of the most common taxa found in coral reefs (Lirman 2001) and one of the most important sources of carbonates to the reef systems (Adey 1998, Villaça 2002.…”

The Todos os Santos bay is a Brazilian coastal marine area that was appointed as top priority for biological conservation. However, there are still too few studies about the local composition of marine communities. The aim of the present investigation was to survey the diversity of marine algae in the sub-tidal zone around the reefs of the Todos os Santos bay. Samples from seven different sites in the bay were obtained by scuba diving through qualitative and quantitative methods, being the collections repeated in rainy and dry seasons. One-hundred and forty-two taxa were found: 31 Chorophyta, 27 Ochrophyta, 83 Rhodophyta, and one Macrophyte. Higher diversity and evenness indices were found during the dry season. Sargassum spp., Dictyopteris delicatula, and Halimeda opuntia were the most abundant macroalgae in the bay. Greatest number of species and most abundant samples were obtained in the oceanic region of the bay, while fewer species and less abundant samples were obtained in areas that are more exposed to the effects of human disturbance. The composition of the flora and abundance of macroalgae in each area of Todos os Santos bay seem to be determined by the quality of local seawater (i.e. degree of eutrophication). Keywords: Macroalgae, tropical bay, reef formation, eutrophication. RESUMO ALGAS MARINHAS BENTÔNICAS DO INFRALITORAL DA BAÍA DE TODOS OS SANTOS (BAHIA, BRASIL). Apesar da Baía de Todos os Santos (BTS) ser considerada uma área de extrema importânciabiológica para a conservação da zona costeira brasileira, poucos estudos sobre as comunidades marinhas de seus ecossistemas foram realizados até o momento. Neste sentido, o objetivo deste trabalho é o de caracterizar a diversidade de algas marinhas do sub-litoral das formações recifais da BTS. Dois tipos de amostragem foram realizados: uma qualitativa e outra quali-quantitativa em sete locais de coleta. Foram identificados 142 táxons, sendo 31 Chlorophyta, 27 Ochrophyta e 83 Rhodophyta, e uma fanerógama marinha. Foi observada uma tendência a maiores valores de diversidade e equitabilidade na época seca. Sargassum spp., Dictyopteris delicatula e Halimeda opuntia foram os táxons que mais contribuíram para a abundância de macroalgas na BTS. O maior número de táxons e os maiores valores de biomassa foram encontrados em local voltado para o mar aberto, enquanto que, os menores valores foram encontrados em locais com algum tipo de distúrbio antrópico. A distribuição da flora e da abundância de macroalgas da BTS é determinada pela condição de eutrofização de cada um dos locais estudados.

“…This genus can be found globally in tropical and subtropical marine waters. Green algae of warmer tropical waters are similar around the world but in colder regions, the northern and southern green seaweeds are markedly different (Costa et al 2002;Tan & Yap 2006). Thus, seaweeds of the Indo-Pacific region are more similar to the macroalgae of Malaysia (Phang et al 2008).…”

“…1). The depth surrounding this reef varies from 6 to 8 m near shore, and may reach up to 15 m in the northeast offshore area (e.g., Costa et al 2002). The Ponto Oeste site (16º24′36″ S, 038º59′08″ W) was visited more than 6 times between Feb 27, 2007 andJan 28, 2008. This site located in a portion of the reef flat ranging from 0.5 and 3 m depth and separated from most reefs flat by crevices, reaching 6 m at the reef base.…”

Nongeniculate coralline red algae are a common element of the Brazilian coastal zone, especially associated to coral reefs. During the course of ecological studies at Parque Municipal Marinho do Recife de Fora, two species of non-geniculate Corallinales were the major organisms covering the reef. Analyses of the vegetative and reproductive features of the species were analyzed; indicating that one new species of the genus Lithothamnion is proposed here based on the combination of several features associated with anatomy of the tetrasporangial conceptacles in relation to other species of the genus for which modern accounts are available. This new proposal along with other new species, new combinations and range extension of some species of the genus based in similar features clearly suggest that stability in species delimitation is possible. The second species found Pneophyllum conicum represents a range extension of more than 6,000 km from the Pacific in to the Atlantic Ocean suggesting that some nongeniculate species are widely distributed. The occurrence and abundance of these species supports and emphasizes the need for an extensive taxonomic reassessment of coralline red algae in the context of Brazilian coral reef biodiversity.
