  pages={258 - 258}
BackgroundThe Hawaiian red algal flora is diverse, isolated, and well studied from a morphological and anatomical perspective, making it an excellent candidate for assessment using a combination of traditional taxonomic and molecular approaches. Acquiring and making these biodiversity data freely available in a timely manner ensures that other researchers can incorporate these baseline findings into phylogeographic studies of Hawaiian red algae or red algae found in other locations.ResultsA… 

Phylogenetic affinities and distribution of the Hawaiian freshwater red algae (Rhodophyta)

This is the first comprehensive survey of the freshwater red algae in Hawaii and revealed 28% endemic taxa, with one putative new species reported from Kauai, highlighting the need for global sampling of freshwaterred algae to infer dispersal patterns, especially for those algae with cosmopolitan distributions.

Characterization of Martensia (Delesseriaceae; Rhodophyta) from shallow and mesophotic habitats in the Hawaiian Islands: description of four new species

Phylogenetic analyses of the rbcL gene resolved five distinct clades of Martensia from the Hawaiian Islands, of which none could be attributed to the two previously used taxonomic names for this flora, providing additional support for the degree of uncharacterized biodiversity from mesophotic depths in the Hawaiian Archipelago.

The Hawaiian Freshwater Algal Database (HfwADB): a laboratory LIMS and online biodiversity resource

The HfwADB is a digital repository that acts as a Laboratory Information Management System for Hawaiian non-marine algal data and can interact with the repository through the web to view relevant habitat data and download images of collection sites, specimen photographs and micrographs, and DNA sequences.

Multilocus phylogeny reveals Gibsmithia hawaiiensis (Dumontiaceae, Rhodophyta) to be a species complex from the Indo-Pacific, with the proposal of G. eilatensis sp. nov.

A multilocus phylogeny of 36 specimens collected throughout the G. hawaiiensis distribution range, showed high genetic diversity at species level, and two major groups were identified, each consisting of multiple lineages.

The Hawaiian freshwater algae biodiversity survey (2009–2014): systematic and biogeographic trends with an emphasis on the macroalgae

The Hawaiian freshwater algal biodiversity survey represents the first comprehensive effort to characterize the non-marine algae of a tropical region in the world using both morphological and molecular tools.

Diversity of Kallymeniaceae (Gigartinales, Rhodophyta) associated with Hawaiian mesophotic reefs

This study provides additional evidence of the extent of diversity in the Kallymeniaceae that is poorly characterized from mesophotic depths and provides further evidence that members of the macroalgal flora contain overlooked biodiversity.

An assessment of diversity within the genus champia (rhodymeniales, rhodophyta) in the Hawaiian Islands

It is concluded that species diversity of Champia is grossly underestimated in the Hawaiian Islands, and the need for a global revision of the genus is highlighted.

Small tropical islands as hotspots of crustose calcifying red algal diversity and endemism

In the tropics, crustose calcifying red algae (Corallinophycidae and Peyssonneliales; CCRA) are dominant and important reef builders that serve a suite of ecological functions affecting reef health.

Inventory of the Seaweeds and Seagrasses of the Hawaiian Islands

This updated list is composed of a total of 661 records, which includes 71 brown algae, 450 red algae, 137 green algae, and three seagrasses, with an overall rate of endemism of 13.2%. Almost half



Phylogenetic affinities of the form taxon Chantransia pygmaea (Rhodophyta) specimens from the Hawaiian Islands

On the basis of phylogenetic analyses, it appears that the region of origin for the B. arcuatum chantransia is East Asia, whereas N. tortuosa came from North America, and the form taxon Chantransia pygmaea is now unequivocally associated with five taxa.

Phylogeography of Asparagopsis taxiformis (Bonnemaisoniales, Rhodophyta) in the Hawaiian Islands: two mtDNA markers support three separate introductions

Parsimony analyses of both regions for the Hawaiian collections revealed relationships that were consistent with those previously published for global A. taxiformis samples, and future studies may only need to sequence one of the two markers.


A thorough sampling along the Canadian coast and using the DNA barcode for the assignment of collections to genetic species to explore algal diversity in the Canadian flora revealed the presence of cryptic diversity within the genera Coccotylus, Mastocarpus, Ozophora, and Stenogramme.

Stream Macroalgae of the Hawaiian Islands: A Floristic Survey1

The flora of Hawai‘i Island appears to be unique only in the sense that it contains fewer broadly distributed taxa than the remaining islands, which may be a function of island age.

Distribution and Reproductive Characteristics of Nonindigenous and Invasive Marine Algae in the Hawaiian Islands

Quantitative and qualitative surveys were conducted on five of the main Hawaiian Islands to determine the current distribution of nonindigenous algae and to assess the level of impact that these

Molecular diversity of Amansieae (Ceramiales, Rhodophyta) from the Hawaiian Islands: a multi‐marker assessment reveals high diversity within Amansia glomerata

Phylogenetic reconstruction based on the SSU gene was largely unresolved, indicating that this marker may be of limited utility for this purpose in this group of algae, but a small amount of nucleotide variation was found for samples of A. glomerata.

A molecular method for identification of the morphologically plastic invasive algal genera Eucheuma and Kappaphycus (Rhodophyta, Gigartinales) in Hawaii

Neighbor-joining analyses were congruent in their separation of Eucheuma and Kappaphycus, and the resulting clusters were consistent with those revealed for global comparisons with the mitochondrial cox2-3 spacer and GenBank data.

The Hawaiian Algal Database: a laboratory LIMS and online resource for biodiversity data

The Hawaiian Algal Database was designed to showcase specimens collected from the Hawaiian Archipelago, enabling users around the world to compare their specimens with the authors', and to provide lab personnel with an organizational tool for storing various biodiversity data types.

Stream Macroalgae of the Hawaiian Islands: a Preliminary Study

Thirty-four stream segments sampled on the four largest Hawaiian Islands had water temperatures ranging from 20 to 27°C, neutral to alkaline pH (6.7-8.0), and relatively low ion content (30-360 JlS

Macroalgae from 23 Stream Segments in the Hawaiian Islands

The number of micro- and macroalgal taxa known from streams in the Hawaiian Islands to 299 infrageneric taxa is extended, and a large percentage of new taxa reported in this study are new records for streams and 15 of these for aquatic habitats.
