The complete chloroplast genome of Chondria tumulosa, a red alga from Manawai (Pearl and Hermes Atoll), Hawai‘i, was determined and analyzed using next-generation sequencing and de novo assembly approaches. The chloroplast genome sequence of C. tumulosa was 172,617 bp and contained 231 genes, consisting of 197 protein-coding genes, 29 transfer RNA...
Only two mitochondrial (mt) genomes had been reported in members of the red algal order Batrachospermales, which are confined to freshwater habitats. Additional mt genomes of six representative members (Batrachospermum macrosporum, Kumanoa ambigua, K. mahlacensis, Paralemanea sp., Sheathia arcuata, and Sirodotia delicatula) were sequenced aiming to...
Little is known about genome organization in members of the order Batrachospermales, and the infra-ordinal relationship remains unresolved. Plastid (cp) genomes of seven members of the freshwater red algal order Batrachospermales were sequenced, with the following aims: 1) to describe the characteristics of cp genomes and compare these with other r...
Considering the lack of knowledge on genetic variation on members of the freshwater red algal of the order Batrachospermales in tropical regions, phylogeographic patterns in Sirodotia populations were investigated using two mitochondrial regions: the cox2-3 spacer and partial cox1 gene (barcode). Individuals identified as Sirodotia delicatula were...
Two genera of the Rhodymeniales, Halopeltis and Leptofauchea, are here reported for the first time from the Hawaiian Islands and represent the deepest records for both genera. Molecular phylogenetic analyses of cytochrome oxidase subunit I (COI), rbcL, and large subunit ribosomal DNA (LSU) sequences for Hawaiian specimens of Leptofauchea revealed o...
Surveys of Hawaiian macroalgae over the past 15 years have yielded numerous specimens representing species new to science. Calliblepharis yasutakei sp. nov. is here described based on a plant collected at a depth of 98 m from Kapou, Pa-pahânaumokuâkea Marine National Monument, Hawaiʻi. Phylogenetic analyses of three molecular markers (COI, rbcL, an...
Molecular phylogenetic analyses of Hawaiian members of the red algal family Dumontiaceae were used to clarify the species diversity of Dudresnaya and Gibsmithia from Hawaiʻi. Although no new species of Dudresnaya were detected in the analyses, D. babbittiana is newly recorded by Lalo, Manawai, and Oʻahu; however, this record remains tentative until...
The calcified encrusting brown algal genus Newhousia is reported from three new archipelagos in the Pacific: (1) Society Islands, French Polynesia; (2) Guam, Mariana Islands; and (3) Vanuatu. Newhousia presents a simple morphology consisting of small, rounded, two-layered calcified blades with limited interspecific variability in morphological feat...
Two new species, one in the genus Incendia, and one in Seiria, are illustrated and described here from mesophotic peyssonnelioid specimens collected in the Hawaiian Islands based on molecular and morphological analyses. Both genera are reported from Hawai‘i for the first time. Incendia lisianskiensis sp. nov. differs from the other nine described m...
A new species of mesophotic marine red algae, Ethelia hawaiiensis sp. nov., is illustrated and described. Ethelia hawaiiensis is distinguished from other members of the genus by its large diameter assurgent filament cells, and in having thallus cavities that are frequently inhabited by microalgae, as well as in DNA sequence. Analyses of mitochondri...
Most genera of the freshwater red algal order Batrachospermales have been systematically revised using
molecular and morphological data, but Sirodotia Kylin remains to be thoroughly reviewed. In this investigation,
DNA sequence data for the rbcL, COI-5P and LSU markers of specimens collected worldwide
were combined with morphological observations t...
Survey cruises by the National Oceanic and Atmospheric Administration (NOAA) in 2016 and 2019 yielded specimens of an undetermined red alga that rapidly attained alarming levels of benthic coverage at Pearl and Hermes Atoll, Papahānaumokuākea Marine National Monument, Hawaiʻi. By 2019 the seaweed had covered large expanses on the northeast side of...
To resolve the paraphyly of Batrachospermum, the sections of the genus have been methodically investigated using DNA sequence data and morphology; this has resulted in the raising of many sections to genus status. Phylogenetic analyses of combined rbcL and COI-5P showed Batrachospermum section Macrospora to be a well-supported clade. We propose Mon...
Sections of the paraphyletic genus Batrachospermum have been recently investigated using molecular (DNA sequence data) and morphological evidence. Some sections have been recognized as distinct genera in order to resolve paraphyly. Batrachospermum species of sections Acarposporophytum and Aristata are showed to form well-supported clades and, in th...
Chroothece has been reported from a range of freshwater environments, including streams, shallow ponds, trickling water on cliffs and moist soils, mostly in Europe and North America. The identification of genera and species morphologically is difficult because of overlaps in critical characters. To help clarify diversity within the genus, samples f...
Phylogeography of Setacea puiggariana, which is widely distributed in southern and south-eastern Brazil, with
few records in South America and Africa, was investigated based on mitochondrial genetic markers: the cox2-3 spacer and the barcode region of cox1 gene. Ten stream segments were sampled across the known geographic distribution in Brazil, wi...
Phylogeography of B atrachospermum viride-brasiliense was investigated using two mitochondrial regions: the cox2-3 spacer and the barcode region of cox1 gene. Eighty-seven individuals were analyzed from nine stream segments throughout its distribution in Brazil. Ten cox2-3 spacer and nine cox1 haplotypes were observed among the individuals studied...
Specimens from southeastern and southern Brazil previously identified as Sheathia arcuata (= Batrachospermum arcuatum) are shown to be members of the recently described genus Nocturama, previously known only from Australia and New Zealand. Morphological and molecular evidence support recognizing the Brazilian specimens as a new species, described h...
Thorea indica sp. nov. is described from the Sai River, Uttar Pradesh, India (26°39’00.7” N, 80°47’38.3” E). Its classification is based on molecular sequences of the plastid-encoded RuBisCO large-subunit gene, rbcL and the barcode region of the mitochondrial encoded cytochrome c oxidase subunit 1, cox1, and morphological data. The sequence analyse...
Degradation of cerrado and the loss of its biodiversity require the revegetation of the areas in this biome, where there are species with little known potential of economical and environmental use. The objective of this work was to evaluate the effect of different sources and levels of nitrogen on growth of seedlings of Gonçalo-Alves(Astronium frax...
RESUMO – A degradação do cerrado e a perda de sua biodiversidade demandam a revegetação de áreas desse bioma, onde existem espécies com potencial de uso econômico e ambiental pouco conhecidos. Este trabalho teve o objetivo de avaliar o efeito de diferentes fontes e doses de nitrogênio sobre o crescimento de mudas de Gonçalo-Alves (Astronium fraxini...

Characterize the biodiversity of the mesophotic macroalgal flora (brown, green and red macroalgae, as well as Cyanobacteria) across the Northwestern Hawaiian Islands (NWHI) and Main Hawaiian Islands (MHI) from 30 to 150 meters depth using both morphological and molecular approaches.
This is a long-term project aiming to describe taxa of most groups of
freshwater red algae based on currently applied and new morphological characters, as well as to infer phylogenetic relationships based on molecular evidences from multiple markers. The project was initially focused on material from Brazil and have expanded to other regions of the world, mainly North America, Europe and Asia depending on the essential participation of collaborators.
