Gracilariaceae are mostly pantropical red algae and include ~230 species in seven genera. Infrafamilial classification of the group has long been based on reproductive characters, but previous phylogenies have shown that traditionally circumscribed groups not monophyletic. We performed phylogenetic analyses using two plastid (universal amplicon rbc L) one mitochondrial ( cox 1) loci from a greatly expanded number taxa to better assess generic relationships understand patterns character...
Abstract An updated synthesis of cyanobacteria and algae information is presented for Brazil aiming to refine the data gathered date evaluate progress biodiversity knowledge about these organisms in country since publication Catálogo de Plantas e Fungos do Brasil. The results 2015 showed an increase 1,250 species (35.7%) when compared 2010, reaching a total 4,747 species. most diverse classes number were Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae...
Hypnea has an intricate nomenclatural history due to a wide pantropical distribution and considerable morphological variation. Recent molecular studies have provided further clarification on the systematics of genus; however, species uncertain affinities remain flawed taxonomic identification. Detailed analyses coupled with literature review indicated strong relationship among H. aspera, cervicornis, flexicaulis, tenuis, suggesting need for studies. Here, we analyzed sequences from two...
The simple and convergent morphologies of many red algae make these species difficult to identify using traditional morphological characters. Many cryptic have been described in recent years based on molecular datasets, this has led the application an integrative taxonomy approach delimitation. Here, we performed several delimitation methods (mBGD, ABGD, SPN, PTP, GMYCs GMYCm) two different loci (COI-5P rbcL) Hypnea cornuta complex. These were combined with phylogenetic data, extensive...
Species in the genus Gracilaria that display conspicuously flattened vegetative morphologies are a taxonomically challenging group of marine benthic red algae. This is result their species richness, morphological similarity, and broad phenotypic plasticity. Within this group, domingensis complex one most common, conspicuous, morphologically variable along tropical western Atlantic Ocean. Previous research has identified members belong to two distantly related clades. However, despite...
The Gracilariaceae comprises 242 mainly tropical species, including some with significant economic value for the food and pharmaceutical industry. Accurate taxonomy is crucial selection of species cultivation. However, identification still challenging taxonomists. Nineteen have so far been referred to Brazilian coast. We describe this diversity across approximately 32 degrees latitude, using mitochondrial (COI-5P) plastid (UPA rbcL) markers in delimitation analyses (ABGD SPN). provide...
The Southwest Atlantic is notable for having extensive reef areas cemented by nongeniculate coralline red algae. Based on an analysis of four genetic markers and morpho‐anatomical features, we clarify the species Harveylithon in tropical warm temperate Atlantic. Species delimitation methods ( mBGD , ABGD SPN PTP ), using three psb A, rbc L, COI support recognition new species: H. catarinense sp. nov., maris‐bahiensis riosmenum previously incorrectly called Hydrolithon samoënse . Our findings...
A detailed morpho-anatomical study of the genus Hypnea from state Bahia is presented. Eight species have been recognized: H. cenomyce, cervicornis, cornuta, musciformis, nigrescens, platyclada, spinella and valentiae. An identification key, as well descriptions, illustrations, comparisons with related taxa maps distribution in for each species, are
A new flat species of Gracilaria, named Gracilaria silviae sp. nov., from the western Atlantic Ocean is described based on comparative morphological and molecular analyses three markers: gene encoding cytochrome oxidase I (cox1), Universal Plastid Amplicon (UPA) large subunit ribulose-1, 5-bisphosphate carboxylase oxygenase (rbcL). has a wide geographic distribution Indian River, Florida, USA, to Santa Catarina, southern Brazil, range habit phenotypes. Across this occupies broad habitats,...
Understanding gaps in academic representation while considering the intersectionality concept is paramount to promoting real progress towards a more inclusive STEM. Here we discuss ways which STEM careers can be sown and germinated so that inclusivity flourish.
Hypnea platyclada sp. nov. is described in detail from plants collected northeastern Brazil and compared with closely related species such as volubilis . The new characterized by a cylindrical estolon stipe, flattened upper portions, fusiform branches, evident axial filament aspect of midrib, tetrasprangia spermatangia forming sori on one side the branchlets, cortical cells unequal size lenticular thickening restricted to extremities filament.
Abstract Hypnea is a monophyletic genus with complex nomenclatural and taxonomic history, an important commercial source of carrageenan. Phylogenies this have been accessed based primarily on Asian species; however, recent studies performed in South America revealed great diversity species, for which phylogenetic relationships need to be evaluated. Three infrageneric sections are recognized the genus: Pulvinatae , Spinuligerae Virgatae ; morphological molecular circumscriptions within each...
Hypnea musciformis occurs widely in the northeast coast of Brazil, and it is one most important natural sources k-carrageenan, which used food cosmetic industries. Despite its potential for exploitation little known about ecology. The aim this study was to investigate biology ecology H. Brazil through analyses biomass stock accompanying flora. Two populations were analyzed: those on beaches Stella Maris Itacimirim (Bahia, Brazil). Eight samplings conducted between 2007 2009 during dry rainy...
Hypnea pseudomusciformis was recently described from South America, and has three morphological variants: "musciformis", "nigrescens", "valentiae". Information on the biology of these variants may help to explain this species' wide variation despite absence genetic divergence among variants. More ecological data accumulated "musciformis" variant occurring Brazilian coast than for others. In study, we reproductive morphology a tropical "nigrescens" population investigated its phenology...
Durante estudo sobre as espécies de Hypnea do litoral estado da Bahia foram encontrados exemplares cornuta (Kützing) J. Agardh em coletas realizadas no extremo sul estado. Este é o primeiro relato H. para Bahia, Brasil. É fornecida uma caracterização detalhada dos aspectos morfológicos, anatômicos e reprodutivos desta espécie.
Abstract A survey of Rhodophyta on the coast Bahia state, northeast Brazil, revealed new records for occurrence a red alga. The specimens were identified as Tolypiocladia glomerulata . We describe morphological characters this species and compare them with literature reports other belonging to genus. This is first record genus from Atlantic Ocean.
Benthic diatoms that produce and live inside mucilage tubes are prominent pioneer colonizers of marine substrata. This adaptation is an ecological strategy related to mechanical protection against wave action desiccation. In this article, we identify Nitzschia martiana based on morphological ultrastructural analyses from several samples, collected different localities. We also analysed the potential distribution model species areas along Brazilian coast with high environmental suitability...
The reproductive phenology and thallus length of Gracilaria birdiae were studied over a period 12 months in natural bed Northeastern Brazil.Fertile specimens G. observed during the entire study period.Tetrasporophytes most common with an annual mean 80.1±5.6%,followed by cystocarpic plants (9.3±3.4%),male gametophytes (8.3±3.6%) infertile (2.2±3.4%).Only male showed variation occurrence frequency year (p<0.05).With respect to length, distinct seasonal was for all stages (p<0.05),with highest...
The growth in the number of molecular sequences produced recent years has provided valuable contributions to knowledge diversity red algae (Rhodophyta) Brazil. However, many works indicate that there is still much be studied. Here, we highlight importance compiling all these data evidence possible taxonomic and geographic gaps through data. So, this study presents a scientometric analysis studies carried out on Brazil, based DNA available public database GenBank. Our results demonstrated an...
