Seaweeds of the Southeastern United States offers a definitive manual for identification seaweeds that inhabit deep offshore waters as well near shoreline and shallow sounds from North Carolina to Florida. The volume provides natural key class, order, family, genera with detailed descriptions, 560 illustrations, an artificial listing simple characteristics quick green, brown, red benthic marine algae (or “bottom growers”) region. The southeastern Atlantic coast is home 334 species seaweed...
The red alga Dasya sylviae C.W.Schneid., M.M.Cassidy & G.W.Saunders sp. nov. is described from mesophotic depths of 60–90 m off Bermuda. Genetic sequences (COI-5P, rbcL) and morphological characteristics show that this species distinct other known pseudodichotomous Dasya. Of ten current in the genus reported Bermuda, only three, D. collinsiana M.Howe, cryptica Quach C.E.Lane punicea (Zanardini) Menegh., share overall pattern branching their axes; however, key features easily distinguish...
Molecular-assisted alpha taxonomy has recently become an effective practice in reassessing biodiversity and floristics for a variety of different organisms. This paper presents series examples that have been drawn from work being carried out on the marine red algae Bermuda. Molecular sequencing DNA Bermuda samples already begun to greatly alter makeup flora as it was known just decades ago, will help set new database future comparison climate change affects species composition islands.
Worldwide coral reefs face catastrophic damage due to a series of anthropogenic stressors. Investigating how ecosystems are connected, in particular across depth, will help us understand if deeper harbour distinct communities. Here, we explore changes benthic community structure 15–300 m depths using technical divers and submersibles around Bermuda. We report high levels floral faunal differentiation with assemblages occupying each depth surveyed, except 200–300 m, corresponding the lower...
Twenty new records from North Carolina are reported including four species of green algae, two brown and fourteen red algae. Nineteen these collections constitute the northernmost species, though most found in Bermudian flora. The other record, that Gigartina stellata (Stackhouse) Batters, represents a southern extension for this northern species. Two previously questionable one known only shallow water verified as members deep offshore A clarification Agardhiella tenera (J. Agardh) Schmitz...
Crassitegula (Sebdeniaceae, Sebdeniales) is a relatively new genus of red algae, currently consisting three species, that was first described based on western Atlantic species in 2006. In the present paper, two are newly from Caribbean and Mediterranean seas, both being detected using COI-5P barcoding, then followed by phylogenetic analysis. bouchetii L.Le Gall & C.W.Schneid. sp. nov. C. garyi represent fourth fifth genus, which, prior to this study, has been confined Bermuda (western...
In the western Atlantic Ocean, brown algal genus Lobophora is currently represented by a single species, L. variegata, with type locality designated Lamouroux as 'Antilles'. this study, we used molecular-assisted alpha taxonomy (MAAT) to assess species diversity of in Bermuda, Florida Keys, St. Croix and Guadeloupe (Lesser Antilles). Using cox1 cox3 sequences barcode markers, five Lobophora, four them novel, were delineated, all previously having been identified area variegata. Our...
AbstractA previously unreported free-living form of Pilayella is described. During all months the year, drifting clouds this plant may carpet up to half sandy bottom and beaches Nahant Bay, a 15 km2 rectangular embayment on north coast Massachusetts. Four features distinguish atypical from typical attached species: (1) ball shape concomitant general lack polarity in development central axes; (2) polystichous condition present throughout much (3) dearth reproductive organs; (4) peak...
Twelve species are added to the flora of North Carolina. One these new records, Compsothamnion thuyoides (Smith) Schmitz, a European taxon, was previously known in western Atlantic only from Bermuda and another, Halymenia hancockii Taylor, formerly type locality, Colombia. questionable record, Lomentaria orcadensis (Harvey) Collins, is verified as member Onslow Bay. Evidence presented support placement Fauchea peltata Taylor Weberella [as W. (Taylor) comb. nov.] on basis newly described...
Recent collections of tetrasporangiate “Heterosiphonia” japonica Yendo from Watch Hill to Point Judith, Rhode Island, represent the first report this nonnative alga in western Atlantic. Native Pacific Ocean, species was unintentionally introduced into European waters by 1984 and has subsequently invaded eastern Atlantic Ocean widely France Norway south Mediterranean Sea. Thus far, all are confined outer coast at present not found Narragansett Bay or Long Island Sound along Connecticut coast....
Abstract An addendum to Schneider and Wynne's A synoptic review of the classification red algal genera a half century after Kylin's “Die Gattungen der Rhodophyceen” (2007; Bot. Mar. 50: 197–249) is presented, with an updating names new taxa at generic level higher. In last few years, several orders families algae have been validated; these are cited referenced below.
Seven marine Rhodophyta are added to the flora of Onslow Bay, North Carolina, four which were also dredged from Long South Carolina.

:With the advent of regular genetic bar coding for taxonomic distinction a decade ago, descriptions morphologically cryptic species have exploded in macroalgal literature. A review this literature is provided. Produced by either convergence morphological characteristics geographically distant or divergence from common ancestor, can often be distinguished subtle anatomical reproductive features. Some pairs, however, remain indistinguishable with overlapping even upon close inspection. Such...
Using sequences of 5' region the cytochrome oxidase subunit 1 gene, large rDNA, and ribulose-1,5-bisphosphate carboxylase/oxygenase gene as genetic markers to elucidate their phylogenetic positions, six unknown species from Western Australia, Tasmania, Lord Howe Is., Norfolk Is. cluster with Meredithia in Kallymeniaceae (Gigartinales), are described new members this previously monospecific genus.

Abstract A second addendum to Schneider and Wynne’s (Schneider, C.W. M.J. Wynne. 2007. synoptic review of the classification red algal genera a half century after Kylin’s “Die Gattungen der Rhodophyceen”. Bot. Mar. 50: 197–249.) “Synoptic review” their is presented, with an updating names new taxa at generic level higher. In past few years, hierarchy some has changed due subfamilies, which are cited referenced below. There have also been descriptions higher in years.
