“…Brachysira microcephala is a cosmopolitan species and can live at a pH of 5.9-6.6 (Vouilloud, 2014). Brachysira microcephala indicated in oligo saprobic to mesotrophic waters with a wide pH range also Brachysira microcephala can live in rivers and swamps with high water temperature, acidic pH, and low conductivity (Vouilloud, 2014). Brachysira microcephala is considered a cosmopolitan species and widespread in Europe (Lange- Bertalot & Moser 1994;Wolfe & Kling 2001;Wojtal, 2003).…”

Diatom biodiversity is an increasing concern due to growing human impact, the study was carried out in one of the most important water storage reservoirs of Tembalang Region. The anthropogenic activity influence of diatom diversity in the UNDIP Reservoir. The reservoir of Universitas Diponegoro (UNDIP) Semarang was an area of 1.24 km2, with the deepest part of 15 meters, and able to accommodate water up to 13500 m3. This study aims to determine the relative abundance, diversity, evenness, dominance of diatoms and is expected to provide information about the condition of the waters in the Diponegoro University Reservoir, Semarang. Littoral benthic diatoms of five locations were sampled. Diatoms slides were prepared from scraping the rock surface with an area of 3x3 cm, dilute in 50 ml distilled water, and identification under the microscope with 1000 magnification. Analysis of the physical characteristics of the waters includes Temperature, pH, DO, TDS, Conductivity, and Turbidity. The diatom composition in UNDIP Reservoir consists of 72 species that belong to 20 genera. The Shannon-Wiener diversity index (H') ranges from 2-3. The dominance index (D) ranges from 0.05-0.17. The Evenness index (E) ranges from 0.54-0.90. Water quality parameters showed a fairly good value in the growth of diatoms. Dominated by periphytic taxa such as Cyclotella meneghiniana (15.72%), Brachysira microcephala (9.93%), and Achnanthidium minutissima (6.84%) which are widely distributed and live at temperatures of 20-30?C and pH >6.

“…Brachysira huitotarum difere de B. brebissonii por apresentar ápices relativamente mais alongados e sub-rostrados, área central delimitada por aréolas mais alongadas, linhas hialinas mais delicadas e maior densidade de estrias. Foi citada como uma espécie perifítica em rios da Amazônia Colombiana, com pH levemente ácido (5,3-6,6) e baixa condutividade (12,0-33,3 μS cm -1 ) (Vouilloud et al 2014). No presente trabalho, foi registrada com hábito epifítico para o Lago dos Bugios, caracterizado como raso, com águas ácidas e pobre em nutrientes (Fernandes 2008).…”

“…Até 1994, Brachysira contava com pouco menos de 15 espécies e a revisão de Lange-Bertalot & Moser (1994) incluiu 32 novas espécies e outras 35 foram transferidas para o gênero. Após esse trabalho, 39 espécies novas foram descritas para o gênero, 22 das quais para a região tropical da América do Sul (Metzeltin & Lange-Bertalot 1998, Vouilloud et al 2014, Mora et al 2017. Outros novos táxons e estudos que ampliaram o número de espécies conhecidas advieram de estudos florísticos, principalmente, regionais (Souza & Compère 1999, Witkowski et al 2000, Wolfe & Kling 2001, Werum & Lange-Bertalot 2004, Shayler & Siver 2004a, 2004b, Anderson et al 2013, van de Vijver 2014, Potapova et al 2014, Kennedy & Allott 2017.…”

RESUMO (Criptógamos do Parque Estadual das Fontes do Ipiranga, São Paulo, SP, Brasil. Algae, 45: Bacillariophyceae (Naviculales: Brachysira)). O levantamento florístico do gênero Brachysira Kützing (Naviculales) do Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP, Brasil, resultou da análise de 31 preparações permanentes de material coletado entre 1991 e 2017. As amostras de água e de substratos (macrófitas e rochas) de sistemas lênticos, riachos e do hidrofitotério foram coletadas e posteriormente oxidadas para análise ao microscópio de luz. Nove espécies e um morfotipo foram encontrados em 15 amostras de material do PEFI, sendo quatro novas citações para o Brasil (Brachysira cf. calcicola Lange-Bertalot, Brachysira frenguellii (Manguin) Lange-Bertalot & Moser, Brachysira huitotarum Vouilloud, Sala & Núñez-Avellaneda e Brachysira intermedia (Østrup) Lange-Bertalot). Brachysira subrostrata Lange-Bertalot foi registrada pela primeira vez no Estado de São Paulo.

“…Colombia contains the highest biological diversity in the world after Brazil (Mittermeier et al 1997); however, most published diatom studies are focused on their ecologies (Martínez & Donato 2003;Díaz-Quirós & Rivera-Rondón 2004;Ramírez & Plata-Dias 2008;Montoya-Moreno et al 2008;Castro-Roal & Pinilla-Agudelo 2014). Recent taxonomic studies of diatoms include the research of (Montoya-Moreno et al 2012), (Vouilloud et al 2013;Sala et al 2013;Vouilloud et al 2010), which focused mainly on specific genera; comprehensive works capable of reflecting the whole diatom community are lacking.…”

This research aimed to study the composition of epilithic diatom flora found in samples collected in Cali River hydrographical basin, Colombia. Quarterly excursions (March, June, September and December of 2012 and March of 2013) were performed in six sampling sites to collect samples for identification of diatom organisms (Class Bacillariophyceae). The results indicated the occurrence of 82 taxa distributed in 26 families and 38 genera. 32 of these are new occurrences in Colombia. The most representative families were Gomphonemataceae, Naviculaceae and Bacillariaceae. The genera richest in species were Navicula, Gomphonema and Nitzschia. Eight species occurred in all sampling sites: Achnanthidium minutissimum, Cocconeis lineata, Cymbella affinis, Gomphonema pumilum var. rigidum, Melosira varians, Navicula symmetrica, Reimeria sinuata and Rhoicosphenia abbreviata. The results indicated 13 species considered dominant and characterize the flora of epilithic diatoms in Cali River hydrographical basin, Colombia.
