Pliocaenicus Bolshetokoensis–A New Species from Lake Bolshoe Toko (Yakutia, Eastern Siberia, Russia)

A new species from the diatom genus Pliocaenicus Round & Håkansson is described from Yakutia (Eastern Siberia, Russia) as Pliocaenicus bolshetokoensis sp. nov., on the basis of light and scanning electron microscopy. The new species is morphologically similar to other members of the genus but differs from the closely related species, Pliocaenicus costatus (Loginova, Lupikina & Khursevich) Flower, Ozornina & Kuzmina and Pliocaenicus seczkinae Stachura-Suchoples, Genkal & Khursevich, mainly by the position of the central fultoportulae and the valve face relief. Variability of quantitative features such as valve diameter, number of striae and areolae in 10 µm, and number of central fultoportulae are similar to data known from other centric genera. The most variable quantitative character of P. bolshetokoensis sp. nov. is valve diameter; the numbers of areolae and striae in 10 µm were less variable. http://dx.doi.org/10.1080/0269249X.2018.1477690 Keywords diatoms, Lake Bolshoe Toko, Russia, new species, taxonomy, Pliocaenicus References [1] Flower R.J., Ozornina S.P., Kuzmina A., & Round F.E., 1998.

Permian–Triassic Non-Marine Algae of Gondwana—Distributions
Earth-Science Reviews 212 (2021) 103382 Contents lists available at ScienceDirect Earth-Science Reviews journal homepage: www.elsevier.com/locate/earscirev Review Article Permian–Triassic non-marine algae of Gondwana—Distributions, natural T affinities and ecological implications ⁎ Chris Maysa,b, , Vivi Vajdaa, Stephen McLoughlina a Swedish Museum of Natural History, Box 50007, SE-104 05 Stockholm, Sweden b Monash University, School of Earth, Atmosphere and Environment, 9 Rainforest Walk, Clayton, VIC 3800, Australia ARTICLE INFO ABSTRACT Keywords: The abundance, diversity and extinction of non-marine algae are controlled by changes in the physical and Permian–Triassic chemical environment and community structure of continental ecosystems. We review a range of non-marine algae algae commonly found within the Permian and Triassic strata of Gondwana and highlight and discuss the non- mass extinctions marine algal abundance anomalies recorded in the immediate aftermath of the end-Permian extinction interval Gondwana (EPE; 252 Ma). We further review and contrast the marine and continental algal records of the global biotic freshwater ecology crises within the Permian–Triassic interval. Specifically, we provide a case study of 17 species (in 13 genera) palaeobiogeography from the succession spanning the EPE in the Sydney Basin, eastern Australia. The affinities and ecological im- plications of these fossil-genera are summarised, and their global Permian–Triassic palaeogeographic and stra- tigraphic distributions are collated. Most of these fossil taxa have close extant algal relatives that are most common in freshwater, brackish or terrestrial conditions, and all have recognizable affinities to groups known to produce chemically stable biopolymers that favour their preservation over long geological intervals. -

This study aimed to document the species of Euastrum (Desmidiaceae) in a subtropical stream adjacent to an important environmental protection area, the Parque Nacional do Iguaçu, in the extreme west of Paraná State, Brazil. For this purpose, monthly samplings of periphytic material associated to Eleocharis minima Kunth were performed in the period between August 2012 and July 2013. This taxonomic inventory allowed the identification of 12 taxa at specific and infraespecific level. Eight new occurrences were recorded for Paraná State:Euastrum attenuatum var. splendens, E. bidentatum var. bidentatum, E. cornubiense var. cornubiense, E. croasdaleae var. croasdaleae, E. denticulatum var. quadrifarium, E. didelta var. quadriceps, E. elegans var. elegans and E. evolutum var. incudiforme. Keywords: biodiversity, desmids, Freshwater, taxonomy, Zygnematophyceae RESUMO - (O gênero Euastrum Ehrenberg ex Ralfs (Desmidiaceae) em um riacho subtropical, área adjacente ao Parque Nacional do Iguaçu, PR, Brasil). Este estudo objetivou documentar as espécies do gênero Euastrum (Desmidiaceae) em um riacho subtropical adjacente a uma importante área de proteção ambiental, o Parque Nacional do Iguaçu, no extremo oeste do Estado do Paraná, Brasil. -

Biota Neotropica. 19(2): e20180568. http://dx.doi.org/10.1590/1676-0611-BN-2018-0568 Abstract: Knowledge of biodiversity in oligotrophic aquatic ecosystems is fundamental to plan conservation strategies for protected areas. This study assessed the diatom diversity from an urban reservoir with oligotrophic conditions. The Piraquara I reservoir is located in an Environmental Protection Area and is responsible for the public supply of Curitiba city and the metropolitan region. Samples were collected seasonally between October 2007 and August 2008. Periphytic samples were obtained by removing the biofilm attached to Polygonum hydropiperoides stems and to glass slides. The taxonomic study resulted in the identification of 87 diatom taxa. The most representative genera regarding the species richness were Pinnularia (15 species) and Eunotia (14 species). -
Vegetative Cell Division and Nuclear Translocation in Three Algae Species of Netrium (Zygnematales, Chlorophyta)

The process of cell division in the three species began with the prominent constriction at the chloroplast in both semicells about half way from the apex. The constriction of chloroplast was mostly visible in N. digitus v. latum. Soon after nucleus divided, septum was formed across the cell and cytokinesis occurred. Observation with fluorescence microscope showed that the movement of nucleus moved back into the center of daughter cells was not always synchronous. Division of chloroplast in N. oblongum and N. digitus v. latum were different with that of N. interruptum. Chloroplast division in two former species occured following the movement of the nucleus down semicell. However, in N. interruptum, chloroplast divided later after nucleus occupied the position at the center of the daughter cells. Cell restoration started after the completion of mitosis and cytokinesis. Key words: Cell division, conjugating alga, mitosis, Netrium ___________________________________________________________________________ The genus Netrium is one of the taxonomically chloroplast and pyrenoid. Mitosis is followed by the formation problematic members of the conjugating green algae (Class of an ingrowing septum, which cuts the symmetrical cell in Zygnematophyceae). -
