Resumo: | The Cladophora genus is one of the most common genera of green algae, widely distributed, occurring from the tropics to the Arctic, has mainly marine habitat, with representatives still occurring in estuaries, brackish and freshwater. Presents morphology easily recognized within the Chlorophyta for possessing stem filamentous uniseriate, branched, formed by giant cells with numerous willing discoid chloroplasts form a parietal reticulum, with bilenticular pyrenoid. Although gender is easily recognizable among the marine green algae, is the one with the greatest difficulties for identification, reflecting the great phenotypic plasticity that has, since the morphology of the stem may vary with age, degree of movement of water, among other habitat features. In addition, the lack of complete and uniform descriptions have contributed to the confusion surrounding the taxonomy of the genus. For better understanding of the relationships between species of Cladophora many molecular phylogenetic studies have been developed, such as the proposition and taxonomic identification of new species, genera and families and intergeneric and intraspecific phylogenetic relationships. However, these are still scarce for tropical regions. On the coast of Brazil the only work that involves the study of DNA data (SSU rDNA) was developed in order to elucidate the molecular phylogenetic relationships of isolates of C. vagabunda occurring along the Brazilian coast. This work was the need to extend this study to other species in Brazil using other molecular markers allied to morphological study of these species. Therefore, there was the taxonomy of species of Cladophora in Brazil based on partial sequences of LSU rDNA, in which 49 were generated sequences. Molecular phylogenetic analysis revealed 17 taxa distributed in two genera: Cladophora (14) and Willeella (3). In Cladophora 14 taxa had their phylogenetic position elucidated, among the four species of Cladophora undetermined, Cladophora sp. 1 has been described as a new species Cladophora codii based on morphological and molecular data, Cladophora sp. 2, Cladophora sp. 3 and Cladophora sp. 4 were separated only in the molecular phylogeny to be described later. The Willeella genus was reestablished by molecular phylogenetic position C. ordinata in a clade separate from other species Cladophora, with specimens C. crispula and C. montagneana, which have been transferred by the authors to Willeella as W. brachyclados. comb. nov. and W. crispula comb. nov. respectively. Cladophora catenata grouping represents a new genus with three species, C. liebetruthii a new member of the genus Microdictyon, first due to the fact diverge from clade of Anadyomene and being and distantly related to other species of Cladophora and C. liebetruthii occurred in a clade with Microdictyon species. They identified 22 species cladoforoides to the coast of Brazil, 19 species of Cladophora and three Willeella. According to this study are new taxa: the two grouping of C. coelothrix of Brazil (nom. prov.) and C. laetevirens of Brazil (nom. prov.), C. prolifera of Brasil (nom. prov.), C. rupestris of Brazil (nom. prov.), Cladophora sp. 2, Cladophora sp. 3 and Cladophora sp. 4. Five species of Cladophora were confirmed only by morphological characters: C. brasiliana, C. corallicola, C. sericea, C. socialis and C. vagabunda. Based on the results it became more evident the need for encouraging more molecular studies expanding the sampling cladophoroids taxa and using more molecular markers to better understand and elucidate the phylogenetic relationships among species. This study contributed to a broader understanding of the molecular phylogenetic relationships of the South Atlantic taxa included in the genus Cladophora and provided more data that will subsidize future investigations |

O g?nero Cladophora ? um dos g?neros mais comuns de algas verdes, amplamente distribu?do, ocorrendo desde as regi?es tropicais ? ?rtica, possui habitat principalmente marinho, com representantes ocorrendo ainda em ambientes estuarinos, salobros e dulc?colas. Apresenta morfologia facilmente reconhecida dentro das Chlorophyta por possuir talo filamentoso unisseriado, ramificado, formado por c?lulas multinucleadas com numerosos cloroplastos discoides dispostos formando um ret?culo parietal, com pirenoide bilenticular. Embora o g?nero seja de f?cil reconhecimento, dentre as clorof?ceas marinhas, ? o que apresenta as maiores dificuldades para identifica??o espec?fica, reflexo da grande plasticidade morfol?gica que apresenta, uma vez que a morfologia do talo pode variar com a idade, grau de movimenta??o da ?gua, dentre outras caracter?sticas do habitat. Al?m disso, a car?ncia de descri??es completas e uniformes t?m contribu?do para aumentar a confus?o em torno da taxonomia do g?nero. Visando um melhor entendimento das rela??es entre as esp?cies de Cladophora muitos trabalhos filogen?ticos moleculares t?m sido desenvolvidos, como os de proposi??o e identifica??o taxon?mica de novas esp?cies, g?neros e fam?lias e de rela??es filogen?ticas intergen?ricas e intraespec?ficas. No entanto, estes ainda s?o escassos para as regi?es tropicais. No litoral do Brasil o ?nico trabalho que envolvia o estudo de dados de DNA (SSU rDNA) foi desenvolvido no intuito de elucidar a rela??es filogen?ticas moleculares de isolados de C. vagabunda ocorrentes ao longo do litoral brasileiro. O presente trabalho partiu da necessidade de se ampliar esse estudo ?s demais esp?cies do Brasil utilizando outros marcadores moleculares aliados ao estudo morfol?gico dessas esp?cies. Diante disso, realizou-se a taxonomia das esp?cies de Cladophora do Brasil baseada em estudos morfol?gicos e an?lise filogen?tica molecular baseada em sequ?ncias parciais de LSU rDNA em sequ?ncias parciais de LSU rDNA, na qual foram geradas 49 sequ?ncias. A an?lise filogen?tica molecular revelou 17 taxa distribu?dos em dois g?neros: Cladophora (14) e Willeella (3). Em Cladophora 14 taxa tiveram a sua posi??o filogen?tica elucidada, dentre estas quatro esp?cies indeterminadas, Cladophora sp. 1, descrita como uma esp?cie nova C. codii, com base em dados morfol?gicos e moleculares e as demais, Cladophora sp. 2, Cladophora sp. 3 e Cladophora sp. 4 foram separadas apenas na filogenia molecular. O g?nero Willeella foi reestabelecido devido ? posi??o filogen?tica molecular de C. ordinata em um clado separado das demais esp?cies de Cladophora, com esp?cimes de C. crispula e C. montagneana, os quais foram transferidos para Willeella, como W. brachyclados comb. nov. e W. crispula comb. nov. De acordo com a an?lise filogen?tica, Cladophora catenata corresponde a um novo g?nero com tr?s esp?cies e, Cladophora liebetruthii um novo membro do g?nero Microdictyon, o primeiro devido ao fato de divergir do clado de Anadyomene por estar e distantemente relacionado ?s demais esp?cies de Cladophora, da mesma forma C. liebetruthii ocorreu em um clado com esp?cies de Microdictyon. Foram identificadas 22 esp?cies cladoforoides para o litoral do Brasil, sendo 19 esp?cies de Cladophora e tr?s de Willeella. Dentre os representantes de Cladophora s?o prov?veis esp?cies novas: os dois agrupamentos de C. coelothrix do Brasil (nom. prov.) e de C. laetevirens do Brasil (nom. prov.), C. prolifera do Brasil (nom. prov.), C. rupestris do Brasil (nom. prov.), Cladophora sp. 2, Cladophora sp. 3 e Cladophora sp. 4. Cinco esp?cies de Cladophora foram confirmadas apenas atrav?s de caracteres morfol?gicos: C. brasiliana, C. corallicola, C. sericea, C. socialis e C. vagabunda. Com base nos resultados obtidos tornou-se mais evidente a necessidade de que sejam desenvolvidos mais estudos filogen?ticos moleculares ampliando a amostragem de taxa cladoforoides utilizando mais marcadores moleculares para um melhor entendimento e elucida??o das rela??es filogen?ticas entre essas esp?cies. Este estudo contribuiu para uma compreens?o mais ampla xii das rela??es filogen?ticas moleculares dos taxa do Atl?ntico Sul inclu?dos no g?nero Cladophora e forneceu mais dados que subsidiar?o investiga??es futurasSubmitted by Verena Pereira (verenagoncalves@uefs.br) on 2019-05-13T22:15:12Z No. of bitstreams: 1 Tese de Doutorado - Aigara Miranda Alves (2015).pdf: 12229089 bytes, checksum: ef867e6b95f8c9534eb17f691738e71a (MD5)Made available in DSpace on 2019-05-13T22:15:12Z (GMT).

The Cladophora genus is one of the most common genera of green algae, widely distributed, occurring from the tropics to the Arctic, has mainly marine habitat, with representatives still occurring in estuaries, brackish and freshwater. Presents morphology easily recognized within the Chlorophyta for possessing stem filamentous uniseriate, branched, formed by giant cells with numerous willing discoid chloroplasts form a parietal reticulum, with bilenticular pyrenoid. Although gender is easily recognizable among the marine green algae, is the one with the greatest difficulties for identification, reflecting the great phenotypic plasticity that has, since the morphology of the stem may vary with age, degree of movement of water, among other habitat features. In addition, the lack of complete and uniform descriptions have contributed to the confusion surrounding the taxonomy of the genus. For better understanding of the relationships between species of Cladophora many molecular phylogenetic studies have been developed, such as the proposition and taxonomic identification of new species, genera and families and intergeneric and intraspecific phylogenetic relationships. However, these are still scarce for tropical regions. On the coast of Brazil the only work that involves the study of DNA data (SSU rDNA) was developed in order to elucidate the molecular phylogenetic relationships of isolates of C. vagabunda occurring along the Brazilian coast. This work was the need to extend this study to other species in Brazil using other molecular markers allied to morphological study of these species. Therefore, there was the taxonomy of species of Cladophora in Brazil based on partial sequences of LSU rDNA, in which 49 were generated sequences. Molecular phylogenetic analysis revealed 17 taxa distributed in two genera: Cladophora (14) and Willeella (3). In Cladophora 14 taxa had their phylogenetic position elucidated, among the four species of Cladophora undetermined, Cladophora sp. 1 has been described as a new species Cladophora codii based on morphological and molecular data, Cladophora sp. 2, Cladophora sp. 3 and Cladophora sp. 4 were separated only in the molecular phylogeny to be described later. The Willeella genus was reestablished by molecular phylogenetic position C. ordinata in a clade separate from other species Cladophora, with specimens C. crispula and C. montagneana, which have been transferred by the authors to Willeella as W. brachyclados. comb. nov. and W. crispula comb. nov. respectively. Cladophora catenata grouping represents a new genus with three species, C. liebetruthii a new member of the genus Microdictyon, first due to the fact diverge from clade of Anadyomene and being and distantly related to other species of Cladophora and C. liebetruthii occurred in a clade with Microdictyon species. They identified 22 species cladoforoides to the coast of Brazil, 19 species of Cladophora and three Willeella. According to this study are new taxa: the two grouping of C. coelothrix of Brazil (nom. prov.) and C. laetevirens of Brazil (nom. prov.), C. prolifera of Brasil (nom. prov.), C. rupestris of Brazil (nom. prov.), Cladophora sp. 2, Cladophora sp. 3 and Cladophora sp. 4. Five species of Cladophora were confirmed only by morphological characters: C. brasiliana, C. corallicola, C. sericea, C. socialis and C. vagabunda. Based on the results it became more evident the need for encouraging more molecular studies expanding the sampling cladophoroids taxa and using more molecular markers to better understand and elucidate the phylogenetic relationships among species. This study contributed to a broader understanding of the molecular phylogenetic relationships of the South Atlantic taxa included in the genus Cladophora and provided more data that will subsidize future investigations |
