A number of species have been persistently misidentified based on morphological similarities to species described from other localities. Some have been assigned to existing taxa not previously reported for the islands, and many have been determined to be novel species. Of late, researchers have substantially modified the ‘Laurencia complex’ in several regions around the globe. Herein, we confirm the presence in Bermuda of five of the eight genera recognized in this complex – Laurencia J.V.Lamouroux, Chondrophycus (J.Tokida & Y.Saito) Garbary & J.T.Harper, Palisada (Yamada) K.W.Nam, Yuzurua (K.W.Nam) Martin-Lescanne and Laurenciella Cassano, Gil-Rodríguez, Senties, Díaz-Larrea, M.C.Oliveira & M.T.Fujii, and discuss the species historically and presently known in the islands. Both rbcL chloroplast sequences and COI-5P mitochondrial sequences support the recognition of at least two species for what has historically been labeled L. obtusa in Bermuda, these assigned to L. dendroidea J.Agardh and L. catarinensis Cordeiro-Marino & M.T.Fujii in molecular analyses. We present two new species, Chondrophycus planiparvus Popolizio, C.W.Schneider & C.E.Lane, sp. nov. and Laurenciella namii Popolizio, C.W.Schneider & C.E.Lane, sp. nov., the latter genetically distinct from L. marilzae (Gil-Rodriguez, Sentíes, Diaz-Larrea, Cassano & M.T.Fujii) Gil-Rodriguez, Sentíes, Diaz-Larrea, Cassano & M.T.Fujii, L. mayaimii Collado-Vides, Cassano & M.T.Fujii and an undescribed species from Brazil. We also used ITS (rRNA) sequences to explore species limits for Laurencia catarinensis, L. dendroidea and L. microcladia Kützing. A full description of Laurencia microcladia, based on recent collections from Bermuda and the Caribbean Sea, is also included in this study.","PeriodicalId":51000,"journal":{"name":"Cryptogamie Algologie","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81182428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to changes in climatic conditions Antarctica is affected by Global warming. The Larsemann Hills area is located in East Antarctica approximately halfway between Vest fold Hills and Amery Ice Shelf on South-eastern coast of Prydz Bay which includes two main peninsulas, the western named Stornes and the eastern named Broknes. The Antarctic environment is highly sensitive and susceptible to the impacts of human activities and has much less natural ability to recover from disturbance than the environment of other continents. Due to coastal location and ice free landscape, Larsemann Hills is an attractive area for human activities which consit on scientific expeditions as well as touristic activities which are currently increasing. It is hypothesized that due to increase in land use pressure, the growth and diversity of Cyanobacteria in this area may be affected. The aim of this study was to record Cyanobacteria from freshwater bodies, rocks and terrestrial habitats. Considering the two main peninsulas, Stornes peninsula comes under the Antarctic Specially Protected Area (ACPA) so the samples were collected from diverse habitats of Broknes Peninsula. Altogether, 16 species of Cyanobacteria belonging to nine genera were recorded from diverse habitat of Broknes Peninsula of Larsemann Hills. This is the first Indian study report of Cyanobacteria of Broknes peninsula of Larsemann Hills. All species are reported for the first time and therefore constitutes new record from this area.","PeriodicalId":51000,"journal":{"name":"Cryptogamie Algologie","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90973353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gomphosphenia Lange-Bert. In particular, Rhoicosphenula has striae/areola features that are similar to Gomphosphenia, but is differentiated from that genus by also having pseudosepta present on both poles of the valves, copulae with septa at one of the poles, and frustules almost rectangular in girdle view. Together, this character combination strongly supports it as an independent genus following modern diatom-taxonomy criteria. Moreover, the only species of Rhoicosphenula known so far was collected from a peculiar acidic and dystrophic habitat, whilst most Gomphosphenia s.s. species colonize medium-conductivity, alkaline inland waters. On the basis of LM and SEM studies, we also propose a species of Gomphosphenia (G. patrickiana Cantonati, Lange-Bert., Kociolek & A.A.Saber, sp. nov.) as new to science. The new species is mainly defined by its valve outline and dimensions, length to breadth ratio, striation density, and geographical distribution. It was found in several samples of two streams in Puerto Rico, sometimes with high relative abundance. Gomphosphenia patrickiana Cantonati, Lange-Bert., Kociolek & A.A.Saber, sp. nov. was much more abundant in the stream with lower nutrient (in particular P) concentrations, and higher ecological integrity. The new species seems to prefer moderately alkaline freshwater habitats with medium-high conductivity and oligo- to mesotrophic conditions, with moderate tolerance to N enrichment. Also noteworthy is the occurrence of the new species in streams with above-average magnesium concentrations (due to the local geology). This Neotropical, warm-water species might be a potential indicator of global warming effects.","PeriodicalId":51000,"journal":{"name":"Cryptogamie Algologie","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90711288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work was also conceived as a starting point for forthcoming investigations using molecular systematics tools and for monitoring the effects of global change on sub-Antarctic marine ecosystems. After a brief history of scientific campaigns, a list of 166 species was established (103 Rhodophyta, 35 Chlorophyta and 28 Ochrophyta [Phaeophyceae]). Molecular systematics studiess have shown the existence of recurrent discrepancies between the established, morphology-based taxonomy and molecular species delimitation, calling for a revision of systematics.

In the Atlantic Iberian Peninsula, L. stictiforme has also been reported based on subtidal collections showing the characteristic morphology described for this species. Recent studies uncovered a diverse complex of cryptic species from the Mediterranean Sea assigned to L. stictiforme. Thereafter, the Atlantic Iberian collections have been re-assessed with the aim of clarifying its taxonomic status. Based on molecular (COI, psbA) and morphological data, the new species Lithophyllum artabricum V.Peña, sp. nov. is described herein. Molecular phylogenetic analyses were congruent in delimiting the Atlantic Iberian collections as an independent lineage from the Mediterranean L. stictiforme complex. Morpho-anatomical characters of the new species showed an overlap with those provided for the Mediterranean clades of L. stictiforme. However, L. artabricum V.Peña, sp. nov. has a monomerous thallus construction whereas the Mediterranean taxa were mainly dimerous. Moreover, L. artabricum V.Peña, sp. nov. differs from other Atlantic European Lithophyllum species by a combination of characters related to the external morphology consisting of single or superimposed lamellae, the monomerous construction, the conical shape of the canal pore of sporangial conceptacles, and by occurring only in subtidal bedrocks. Lithophyllum artabricum V.Peña, sp. nov. is at present known from northern Spain to northern Portugal. One collection of L. stictiforme from southern Portugal showed similarities with L. artabricum V.Peña, sp. nov.; however, DNA sequence data are necessary to confirm this record. Based on the evidence presented herein, L. stictiforme is removed from the flora of northern and northwestern Spain, and northern Portugal. The finding of cryptic diversity in L. stictiforme suggested that further reports of this species in warm and temperate waters should be re-assessed.","PeriodicalId":51000,"journal":{"name":"Cryptogamie Algologie","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81401341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The islands harbour a rich marine biota with a number of endemic species. A recent collection trip and molecular genetic studies using the rbcL marker revealed the presence of three entities of the genus Ulva L. (Ulvales, Chlorophyta) on the islands. One of these we describe herein as Ulva piritoka Ngāti Kuri, Heesch & W.A.Nelson, sp. nov.

We also confirmed the presence of Ulva compressa L. and Ulva rigida C.Agardh, both of which, although present on the New Zealand mainland, were originally described from Europe and are considered introductions to the New Zealand archipelago.

In this investigation, DNA sequence data for the rbcL, COI-5P and LSU markers of specimens collected worldwide were combined with morphological observations to assess their specific diversity, infer their relationships and evaluate the morphological characters relevant for species identification. Phylogenetic analyses showed the genus to be a monophyletic lineage with high support. Inter- and intra-specific divergence values were well-delineated with higher interspecific (2.1-7% and 4.4-10.5%) and lower intraspecific (0-2.4% and 0-3.8%) variations for rbcL and COI-5P sequences, respectively. LSU sequences revealed lower interspecific divergence values than the COI-5P sequences (0.7-3.3%) indicating less resolution as a barcode marker. Nine species are recognized based on DNA sequence data, morphological characters and geographic distribution. Five species were previously described (S. assamica Necchi, Rossignolo, Yasmin, J.A.West & Ganesan, S. delicatula Skuja, S. huillensis (Welwitsch ex West & GSWest) Skuja, S. kennedyi A.L.Szinte, J.C.Taylor & M.L.Vis and S. suecica Kylin) and four new species are proposed (S. amazonica Necchi, N.L.Rossignolo & M.O.Paiano, sp. nov., S. aquiloamericana Necchi, N.L.Rossignolo & M.L.Vis, sp. nov., S. cryptica Necchi, N.L.Rossignolo & M.O.Paiano, sp. nov. and S. delicatuliformis Necchi, N.L.Rossignolo & M.O.Paiano, sp. nov.). Diagnostic characters for the genus are confirmed to be carpogonia asymmetric with a basal protuberance and carposporophytes diffuse with indeterminant prostrate filaments producing determinate erect branches terminating in carposporangia. The following morphological characters were applied to distinguish species: primary fascicle cell number, spermatangial arrangement, origin of gonimoblast filament and size of carposporangia. Based on morphology, S. sinica, S. segawae and S. yutakae are proposed as synonyms of S. suecica and S. ateleia Skuja of S. delicatula. The status of three species (S. cirrhosa Skuja ex M.S.Balakr. & B.B.Chaugule, S. gardneri Skuja ex Flint and S. huangshanensis Z.X.Shi & S.L.Xie) could not be confirmed due to lack of type specimens and published information on informative diagnostic characters.","PeriodicalId":51000,"journal":{"name":"Cryptogamie Algologie","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89609051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
