“…In both countries, there are strikingly similar numbers of Chlorophyta and Phaeophyceae species, but a substantial difference in total species numbers between these two countries is caused by the considerably higher number of Rhodophyta species reported for Costa Rica (288 vs. 103 spp.). Recent published studies on marine algae in Panama have been focused more on green and brown algae (Wysor and De Clerck 2003;Wysor and Kooistra 2003;Wysor 2004). According to Wysor (personal communication 2007), Rhodophyta have been collected in Panama as well; however, these results have not been published yet.…”

“…Despite their ecological importance, our knowledge about the taxonomic diversity of the marine benthic flora in Central America is far from complete. Apart from the basic works of Taylor (1945Taylor ( , 1960 and Dawson (1960) on the marina flora of Central America and adjacent regions, several publications provide annotated species lists for marine algae from Panama (Earle 1972;Wysor and De Clerck 2003;Wysor and Kooistra 2003;Wysor 2004), Belize (Norris and Bucher 1982;Littler et al 1995Littler and Littler 1997), Guatemala (Bird and McIntosh 1979), Nicaragua (Dawson 1962;Phillips et al 1982), El Salvador (Dawson 1961), and Honduras (Ogden 1998). However, most of these studies concern the Caribbean coast of Central America, while information on the diversity of the benthic marine flora remains scarce for the eastern tropical Pacific coast of the region (Dawson 1957(Dawson , 1960Wysor 2004).…”

New records of benthic marine algae and Cyanobacteria for Costa Rica, and a comparison with other Central American countries

We present the results of an intensive sampling program carried out from 2000 to 2007 along both coasts of Costa Rica, Central America. The presence of 44 species of benthic marine algae is reported for the first time for Costa Rica. Most of the new records are Rhodophyta (27 spp.), followed by Chlorophyta (15 spp.), and Heterokontophyta, Phaeophycea (2 spp.). Overall, the currently known marine flora of Costa Rica is comprised of 446 benthic marine algae and 24 Cyanobacteria. This species number is an under estimation, and will increase when species of benthic marine algae from taxonomic groups where only limited information is available (e.g., microfilamentous benthic marine algae, Cyanobacteria) are included. The Caribbean coast harbors considerably more benthic marine algae (318 spp.) than the Pacific coast (190 spp.); such a trend has been observed in all neighboring countries. Compared to other Central American countries, Costa Rica has the highest number of reported benthic marine algae; however, Panama may have a similarly high diversity after unpublished results from a Rhodophyta survey (Wysor, unpublished) are included. Sixty-two species have been found along both the Pacific and Caribbean coasts of Costa Rica; we discuss this result in relation to the emergence of the Central American Isthmus.

“…Recent attempts to increase knowledge of the marine algal fl ora in Panama have included intensive sampling to better estimate biodiversity. These efforts have resulted in reports that indicate substantially more marine algal species than previously documented for the country (Wysor et al 2000, Wysor and De Clerck 2003, Wysor and Kooistra 2003, Wysor 2004 ). This study is part of a greater collaborative effort to survey and inventory the Panamanian marine algal fl ora.…”

Only two species of Polysiphonia sensu lato (predominately species of Polysiphonia and Neosiphonia ) have been reported from Caribbean Panama. In contrast, 16 species are documented from the neighboring countries of Costa Rica and Colombia. Molecular-assisted identifi cation using plastidencoded ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit gene ( rbc L) and mitochondria-encoded cytochrome c oxidase subunit I gene (COI) loci identifi ed 14 species from 38 samples collected along the Caribbean coast of Panama. Morphological character states were examined and used to identify each sample, and phylogenetic relationships among these species were estimated through maximum likelihood analyses of rbc L and nuclear-encoded SSU sequence data. Neosiphonia ferulaceae , N. tongatensis , Polysiphonia binneyi , P. havanensis , P. macrocarpa , P. pseudovillum , P. schneideri , P. subtilissima , and two species that could only be identifi ed as P. cf. sertularioides are reported for the fi rst time from Panama. Polysiphonia pentamera , a species only known from the eastern Pacifi c is reported for the fi rst time in the Caribbean, and two new species, P. lobophoralis and P. nuda are described. A key to Caribbean Panama species, descriptions of species morphology and remarks on taxonomy and relationships are provided. These fi ndings demonstrate that previous limited reports of Polysiphonia sensu lato species from Panama resulted from a lack of study, rather than a lack of diversity, within the region.

Abstract:The metabolomic techniques are powerful tools to explain and predict phenotypes in biological systems. In this area, chemometric methods are employed in order to extract information from complex analytical data. Among the instrumental methods that allow obtaining analytical and chemometric methods, proton nuclear magnetic resonance ( 1 H NMR) and partial least squares discriminant analysis (PLS-DA) are the most used. This paper describes some practical issues in pretreatment 1 H NMR spectra and the use of PLS-DA with and application for differentiation of two species of brown algae, Dictyota ciliolata e D. crenulata. Keywords:Metabolomics; PLS-DA; 1 H NMR; chemotaxonomy; brown algae; Dictyota. ResumoAs técnicas de metabolômica são ferramentas poderosas para explicar e prever fenótipos em sistemas biológicos. Nesta área, os métodos quimiométricos são empregados para extrair informações de dados analíticos complexos. Dentre os métodos instrumentais para obtenção dos dados analíticos e os métodos quimiométricos, os mais utilizados são ressonância magnética nuclear de hidrogênio (RMN de 1 H) e o método dos mínimos quadrados parciais discriminante (partial least squares-discriminant analysis, PLS-DA). O presente trabalho descreve alguns aspectos práticos do processamento de espectros de RMN de 1 H e da utilização de PLS-DA com aplicação para diferenciação de duas espécies de algas pardas, Dictyota ciliolata e D. crenulata.
