“…In general ITS sequences become difficult to align as soon as the much slower SSU arrives within the window of phylogenetic interpretability (Bakker et al, 1994(Bakker et al, , 1995a(Bakker et al, , 1995b. In Halimeda, however, elevated rates of SSU regions in comparison to those of other green algae (Zechman et al, 1999) close in on depressed rates among ITS regions.…”

“…The Indo-Pacific representatives share the habitat with several other Halimeda species (H. distorta, H. hederacea, H. micronesica, H. minima) and do not cover reefs to the same extent as their Caribbean relatives. Only a few other seaweed phylogeographic studies have elucidated dispersal directionality (Bakker et al, 1995b;Peters et al, 1997;Van Oppen et al, 1995).…”

Halimeda (Bryopsidales), a genus of calcified, segmented green seaweeds, abounds in reefs and lagoons throughout the tropics. To investigate phylogenetic, phylogeographic, and historic ecological relationships of the genus, the nuclear rDNA including the SSU and both ITS regions were sequenced. A maximum likelihood tree revealed the following: (1) there were anatomical and morphological synapomorphies for five well-supported lineages; (2) the last common ancestor of one lineage invaded sandy substrata; those of two other lineages established in wave-affected habitats, whereas the cenancestor of the remaining two lineages occupied sheltered rocky slopes. Yet, several species adapted to new habitats subsequently, resulting in several cases of convergence; (3) all lineages separated into Atlantic and Indo-Pacific daughters, likely resulting from the rise of the Panamanian Isthmus. Each daughter pair gave rise to additional convergent species in similar habitats in different oceans; (4) Halimeda opuntia, the only monophyletic pantropical species detected so far, dispersed from the Indo-Pacific into the Atlantic well after the closure event; (5) minor SSU-sequence differences across species and phylogeographic patterns of vicariance indicated a relatively recent diversification of the extant diversity. Cretaceous and Early Tertiary fossil look-alikes of modern species must then have resulted from iterative convergence. Ó

“…E-mail: frederik. leliaert@ugent.be Examples include cryptic species in C. vagabunda (Linnaeus) van den Hoek (Bakker et al, 1995a) and C. coelothrix Ku¨tzing (Leliaert et al, 2007a), and C. albida (Nees) Ku¨tzing and C. sericea (Hudson) Ku¨tzing forming a morphologically diverse species complex (Bakker et al, 1995b). Although the exact number of species along the Atlantic coasts of Europe is uncertain, 18 morphospecies are currently recognized based on differences in habit, mode of attachment, organization of branch systems (acropetal with cell divisions largely confined to the apical cells, or irregular with many intercalary cell division), number of branches per node, insertion of the branches (apical with a slightly inclined cross wall or lateral with a steeply inclined cross wall), cell shape and dimensions, and thickness of the cell walls (van den Hoek, 1963;Leliaert & Boedeker, 2007).…”

Cladophora rhodolithicola sp. nov., a small green macroalgal epiphyte on rhodoliths, is described from the Atlantic coasts of the British Isles, France and Spain, based on morphological and molecular evidence. Molecular phylogenetic analyses reveal that the rhodolith epiphyte is closely related to C. pygmaea, a dwarf species that also grows on maerl and small stones and whose systematic position was previously uncertain. The fact that both species, along with two other distinct Cladophora species (C. echinus and C. battersii), are resolved among species traditionally assigned to the Cladophora section Longiarticulatae, has implications for our understanding of the evolution of the genus. The section Longi-articulatae is one of the most distinctive groups in Cladophora, being characterized by coarse thalli with conspicuous basal cells, strict acropetal growth and the lack of intercalary rhizoids. Here we show that deviant character states such as reduced and irregular growth, and intercalary rhizoids have evolved independently several times within this clade.

“…They concluded that there is no basis for independent recognition of Cladophorales and Siphonocladales because the fi rst is paraphyletic and the second is polyphyletic. Bakker et al (1995) studied the global phylogeography of the cosmopolitan C. vagabunda and concluded that this species represents an intermediary case between the old tropical species, that show a wellmarked vicariance, and cold-temperate to boreal, more recently derived strains that do not present a well-marked vicariance. Hoek & Chihara (2000) presented the taxonomic revision of the species of Cladophora from Japan to Russian Far-East, recording the occurrence of 32 taxa and a new approach to the distribution of the species inside the morphological sections was given according to phylogenetic relationships based on SSU rDNA sequences.…”

-(Phylogenetic analyses of Cladophora vagabunda (L.) C. Hoek (Cladophorales, Chlorophyta) from Brazil based on SSU rDNA sequences). The complete SSU rDNA was sequenced for 10 individuals of Cladophora vagabunda collected along the coast of Brazil. For C. rupestris (L.) Kütz. a partial SSU rDNA sequence (1634 bp) was obtained. Phylogenetic trees indicate that Cladophora is paraphyletic, but the section Glomeratae sensu lato including C. vagabunda from Brazil, Japan and France, C. albida (Nees) Kütz., C. sericea (Hudson) Kütz., and C. glomerata (L.) Kütz. is monophyletic. Within this group C. vagabunda is paraphyletic. The sequence identity for the SSU rDNA varied from 98.9% to 100% for the Brazilian C. vagabunda, and from 98.3% to 99.7% comparing the Brazilian individuals to the ones from France and Japan. Sequence identity of the Brazilian C. vagabunda to C. albida and C. sericea vary from 98.0% to 98.6%. The SSU rDNA phylogeny support partially the morphological characteristics presented by Brazilian populations of C. vagabunda. On the other hand, C. rupestris from Brazil does not group with C. rupestris from France, both sequences presenting only 96.9% of identity. The inclusion of sequences of individuals from Brazil reinforces the need of taxonomical revision for the genus Cladophora and for the complex C. vagabunda.Key words -Brazil, Cladophora vagabunda, Cladophorales, molecular phylogeny, SSU rDNA RESUMO -(Análises fi logenéticas de Cladophora vagabunda (L.) C. Hoek (Cladophorales, Chlorophyta) do Brasil, baseada nas seqüências SSU rDNA). A seqüência completa do SSU rDNA foi obtida para 10 indivíduos de Cladophora vagabunda coletadas ao longo da costa do Brasil. Uma seqüência parcial do SSU rDNA (1634 bp) foi obtida para C. rupestris (L.) Kütz. As árvores fi logenéticas indicam que Cladophora é parafi lético, mas a seção Glomeratae sensu lato compreendendo C. vagabunda do Brasil, Japão e França, C. albida (Nees) Kütz., C. sericea (Hudson) Kütz. e C. glomerata (L.) Kütz., é monofi lética. Dentro deste grupo, C. vagabunda é parafi lética. A identidade da seqüência para o SSU rDNA variou de 98,9% à 100% para C. vagabunda brasileira e de 98,3% a 99,7% quando comparados os indivíduos brasileiros aos da França e do Japão. A identidade da seqüência entre C. vagabunda brasileira e as duas outras espécies (C. albida e C. sericea) variou entre 98,0% e 98,6%. A fi logenia do SSU rDNA suporta parcialmente as caracteristícas morfológicas apresentadas pelas populações brasileiras de C. vagabunda. Por outro lado, C. rupestris do Brasil não se agrupou a C. rupestris da França, as duas seqüências apresentaram somente 96,9% de identidade. A inclusão de seqüências de indivíduos do Brasil reforçam a necessidade de uma revisão taxonômica para o gênero Cladophora e para o complexo C. vagabunda.
