“…Remarks: The Punta Burica specimens closely matched the vegetative morphology of Brazilian H. flava, but reproductive specimens were not available when the species was orginally described by Nauer et al [61], and tetrasporophytic thalli are described here for the first time. This is the first report of the species outside of Brazil.…”

Molecular Assisted Identification Reveals Hidden Red Algae Diversity from the Burica Peninsula, Pacific Panama

Abstract:The marine flora of Panama harbors a rich diversity of green, red and brown algae, and despite chronic understudy, it is reported as the second most diverse marine flora along the Pacific Central American coast, with 174 macroalgal species. Extensive new collections and molecular assisted identification (MAI) by an international team of researchers has revealed an even greater diversity for this country. Here, the intertidal and shallow subtidal marine flora of the remote Burica Peninsula is introduced. This area is characterized by an uplifted extensive intertidal flat composed of firm, sedimentary benthos known as mudrock, on which abundant algal communities thrive, even during extended periods of exposure. A collection of nearly 200 brown, green and red macroalgae specimens representing the first marine floristic inventory of this region was made in January 2011, and results of analyses of 45 foliose red algae specimens are presented. DNA sequence data for several loci (rbcL-3P; COI-5P; UPA) have been generated for molecular assisted identification and to guide morphological assessments. Twenty-six species were identified among the specimens including 21 new Pacific Panama records, as well as previously unrealized transisthmian distributions, and two new species, Neorubra parvolacertoides sp. nov. and Grateloupia irregularis sp. nov.

“…A divergência interespecífica para Bostrychia encontrada por Fontes (2012) para o rbcL (9,1% a 22,5%) mostrou uma amplitude de variação maior do que o observado nos nossos resultados. Para outros gêneros de algas vermelhas foram observadas amplitudes de variação menores, como, por exemplo, para Hypnea (3.2%-6.8%, Nauer et al 2014Nauer et al , 2015 …”

“…Estudos com diferentes grupos de algas vermelhas marinhas e continentais tem demonstrado que o COI-5P é um marcador eficiente para a discriminação de espécies, incluindo a detecção de espécies crípticas (Clarkston & Saunders 2010, Costa et al 2012, Milstein et al 2012, Paiano & Necchi 2013, Agostinho & Necchi 2014, Machín-Sánchez et al 2014, Nauer et al 2014, Saunders & Millar 2014 Contudo, os primers originais propostos por Saunders (2005) não são eficientes para todos os grupos de algas vermelhas. De fato, um dos maiores problemas na utilização do COI-5P é a falta de primers universais para amplificação, o que tem requerido a utilização de diferentes combinações de primers ou mesmo a utilização de marcadores alternativos (Saunders 2005, Clarkston & Saunders 2010, Milstein et al 2012.…”

Studies on the diversity of macroalgae from mangroves in Brazil have been based only on morphological approaches, in which characters used are unstable and uninformative for the species identification and delimitation. In this context, macroalgae of mangroves were investigated for the first time in the Brazilian coast using a molecular approach, having as target of our study the mangrove of the Barnabé Island, Santos, São Paulo.DNA Barcode markers UPA and COI-5P were used, besides the rbcL, largely used for phylogenetic inferences, and also SSU rDNA. In addition to these, the ITS and tufA markers were used exclusively for the green algae, the latter unsuccessfully. Fifteen species were recorded for the studied area, ten Rhodophyta and five Chlorophyta. Of these, two are new records for the State of São Paulo, Caloglossa apomeiotica e Boodleopsis vaucherioidea. Of the four species of the genus Bostrychia identified in this study: "Bostrychia calliptera ", B. montagnei, B. moritziana and B. radicans, only B. montagnei proved to be a molecular and morphologically well-defined species. The other species formed complexes with different molecular lineages. For B. radicans and B. moritziana, the analyses showed three and two molecular lineages, respectively, of the seven identified for the B. radicans/B. moritziana complex in the literature. The taxon identified as "B. calliptera" showed high molecular divergence with sequences of B.calliptera from Brazil, presenting morphology "B. pinnata", a taxon currently reduced to a synonym of B. calliptera. Caloglossa species, except C. ogasawaraensis, are difficult to identify due to the subtle morphological characters considered of diagnostic value, and their considerable phenotypic plasticity. Caloglossa apomeiotica, C. confusa and C. leprieurii were identified primarily by the use of molecular markers. Caloglossa apomeiotica can be segregated from the others by the presence of bisporangia, which makes unreliable morphological identification when collected infertile thalli, while C. confusa has strongly constricted thallus nodes. The molecular data obtained for Catenella caespitosa from SSU sequences suggest that the citations of this species for the Brazilian coast may be misleading since they have high intraspecific divergence with C. caespitosa from database. Due to the lack of sequences from the type locality, sequences of DNA barcode markers, and a major molecular sampling of Catenella species in databases, became impossible to reach a conclusive result. The obtaining of sequences for green algae was extremely problematic, making impracticable a broader comparison between the collected species. Of the two collected species of Boodleopsis, only two partial sequences of rbcL were obtained for B. vaucherioidea and none for B.pusilla. The comparison with the unique sequence of Boodleopsis deposited in databases, a partial rbcL sequence of B. pusilla, revealed low molecular divergence with our sequences of B. vaucherioidea. Besides the need to obtain complete seque...
