A STUDY ON DIATOMS OF THE ARTIFICIAL PONDS AND LAKES OF THE NATIONAL BOTANICAL GARDEN, IRAN T. Nejadsattari, Z. Shariatmadari, & Z. Jamzad Nejadsattari,T., Z. Shariatmadari, and Z. Jamzad 2007 008 01: A study on Diatoms of the artificial ponds and lakes of National Botanical Garden, Iran. – Iran. Journ. Bot. 13 (1): 6-11. Tehran. Five aquatic sites of National Botanical Garden of Iran monthly were sampled from December 2003 to November 2004. Total number of 68 genera in 18 families and 11 orders of the planktonic Diatoms were identified. Among the families Bacillariaceae with 19 genera and species showed the highest species richness. Cymbellaceae (11 species), Naviculaceae (7 species), Surirellaceae (6 species), Pleurosigmataceae (4 species), Fragilariaceae and Achnanthaceae each with 4 species, Pinnulariaceae and Gomphonemaceae each with 2 species and Rhopalodiaceae, Cosmioneidaceae, Diadesmidiaceae, Amphipleuraceae, Catenulaceae, Melosiraceae, Mastogloiaceae, Stephanodiscaceae, Anomoeoneidaceae each with 1 species respectively presented in the studied sites. High population densities of species were observed in the cold seasons.

    Protistology Diatom Assemblages of the Brackish Bolshaya Samoroda

    Protistology 13 (4), 215–235 (2019) Protistology Diatom assemblages of the brackish Bolshaya Samoroda River (Russia) studied via light micro- scopy and DNA metabarcoding Elena A. Selivanova, Marina E. Ignatenko, Tatyana N. Yatsenko-Stepanova and Andrey O. Plotnikov Institute for Cellular and Intracellular Symbiosis of the Ural Branch of the Russian Academy of Sciences, Orenburg 460000, Russia | Submitted October 15, 2019 | Accepted December 10, 2019 | Summary Diatoms are highly diverse and widely spread aquatic photosynthetic protists. Studies of regional patterns of diatom diversity are substantial for understanding taxonomy and biogeography of diatoms, as well as for ecological perspectives and applied purposes. DNA barcoding is a modern approach, which can resolve many problems of diatoms identification and can provide valuable information about their diversity in different ecosystems. However, only few studies focused on diatom assemblages of brackish rivers and none of them applied the genetic tools. Herein, we analyzed taxonomic composition and abundance of diatom assemblages in the brackish mixohaline Bolshaya Samoroda River flowing into the Elton Lake (Volgograd region, Russia) using light microscopy and high-throughput sequencing of the V4 region of the 18S rDNA gene amplicons. In total, light microscopy of the samples taken in 2011–2014 and 2018 allowed to distinguish 39 diatom genera, represented by 76 species and infraspecies taxa. Twenty three species of diatoms were recorded in the river for the first time. Next-generation sequencing revealed a larger number of diatom taxa (26 genera and 47 OTUs in two samples vs. 20 genera and 37 species estimated by light microscopy). As a result, sequences of Haslea, Fistulifera, Gedaniella were recorded in the river for the first time.

The morphology of the new species, named Cymbella pami- rensis, is discussed and compared to similar species. The main morphometric features distinguishing Cymbella pamirensis from similar species of Cymbella are the outline and size of the valves. Cymbella pamirensis has been observed in surface sediment and core samples from Lake Sate Baile Dikuli, an alkaline, mesotrophic lake of the Pamir Mountains.

Surirella wulingensis sp. nov., discovered from Li River (located in Wuling Mountains, China), bears five undulations from pole to pole throughout the whole valve diminution series and parallel valve margins, which differ from other similar taxa. Based on the observations of the fine structure, an amended description is provided for S. tientsinensis which possesses a unique character within the genus Surirella: rounded and rimmed outer openings of areolae. Three new morphological terms are proposed: costa–stria bundle (CSB), over–fibula costa (OFC), and mantle sinking against a fibula (MSAF), which can be used for describing someSurirella taxa more succinctly and explicitly including these taxa in this study. Key words: corresponding relationship, diatom, fine structure, new species, rimmed opening Introduction Surirella sensu stricto, they are still a distinctive group with unique valve surface undulations from pole to Surirella Turpin is a diversified diatom genus that in- pole.

Müller from material collected in East Africa at the end of the 19th and the beginning of the 20th century were re-evaluated and lectotypes designated. rhopalodiella as anew subgenus is proposed which refines O. Müller’s infrageneric classification and to which all these taxa belong. In addition, the type of epithemiarhopala,described by Ehrenbergfrom Egypt, was studied to examine the assumed synonymy,introduced by Hustedt, with some of Müller’s species. This study,using light and scanning electron microscopy,was not only based on historic material but also more recent material from Africa, including samples from the Island of Reunion from which the new species epithemia vandevijveri is described. The distribution of epithemia subg. rhopalodiella,known to be restricted to tropical Africa, is discussed based on literature data and own observations. Corresponding to recent molecular-based studies, rhopalodia is given anew status as subgenus.

    A Preliminary Check-List of the Algae of Ireland Michael D. Guiry

    A Preliminary Check-list of the Algae of Ireland Michael D. Guiry Ryan Institute NUI Galway September 2019 i Introduction The present check-list is an initial attempt to provide an up-to-date list of the current names for freshwater, marine and terrestrial (including aerophytic) algae of Ireland. The list is extracted from the distributional data in AlgaeBase (https://www.algaebase.org) as of September 2019, and each name and its source is traceable on line there. Some 2879 current species names are presently included. Taxa at the subspecies, varieties and formae level are not provided. The list is current as of September 2019. Nine phyla/divisions are included, eight of them from the Eukaryota and one (Cyanobacteria) from the Prokaryota. Table 1. Included taxa.

The final list is likely to exceed 5000 species, or about 10% of the world’s species of algae. Poor coverage is apparent for diatoms, some green algae, Cryptophytes and Glaucophytes, and dinoflagellates. The list is arranged in alphabetical order within phyla, classes, orders, families and genera.

The knowledge of occur in the Capibaribe River estuary, Pernambuco, composition and life forms of the biotic communities is Brazil. This is a highly impacted ecosystem by anthropic a necessary tool to understand the mechanism and the activities. We collected samples of the phytoplankton ecological importance of aquatic ecosystems (Eskinazi- community at three stations, during three months of Leça et al. 2004; Cloern and Jassby 2010). each season: dry, from October to December 2010; rainy, In this context, our study aimed to analyze the from May to July 2011. We collected samples during the composition of the phytoplankton community and the low and high tide, at the spring tide. We classified the main life forms of species occurring in the Capibaribe species based on life forms. We identified 127 taxa, and River estuary (Pernambuco), which is an important the majority of species were freshwater planktonic form aquatic body in Northeast Brazil.

Abstract The biodiversity of the entrance zones of the Montenegro caves is barely studied, therefore the purpose of this study was to assess the biodiversity of several caves in Montenegro. The samples of phototrophs were taken from various substrates of the entrance zone of 7 caves in July 2017. A total of 87 species of phototrophs were identified, including 64 species of algae and Cyanobacteria, and 21 species of Bryophyta. Comparison of biodiversity was carried out using Jacquard and Shorygin indices. The prevalence of cyanobacteria in the algal flora and the dominance of green algae were revealed. The composition of the phototrophic communities was influenced mainly by the morphology of the entrance zones, not by the spatial proximity of the studied caves. Key words: karst caves, entrance zone, ecotone, algae, cyanobacteria, bryophyte, Montenegro. Introduction The subterranean karst forms represent habitats that considered more climatically stable than the surface.
