Diatomáceas perifíticas da represa Itaqui, São José dos Pinhais, Paraná: Fragilariales, Eunotiales, Achnanthales e Gomphonema Ehrenberg

Abstract

Periphytic diatoms from Fragilariales, Eunotiales, Achnanthales and Gomphonema Ehrenberg taxa were studied from a reservoir of the Itaqui River, in São José dos Pinhais, PR. Glass slides were used as artificial substrate that was collected after 30 days of incubation.

Gomphonema Ehrenberg (Bacillariophyceae, Gomphonemataceae) of the São Francisco Falso River, Paraná, Brazil

“…Geographic distribution for Paraná State: Curitiba, Tijucas do Sul, Ponta Grossa, Fazenda Rio Grande (Tremarin et al 2009b), São José dos Pinhais (Faria et al 2010).…”

“…Geographic distribution for Paraná State: Antonina, Curitiba, Ponta Grossa, Porto Rico, Capitão Leônidas Marques, Ipiranga, Telêmaco Borba, Sapopema, Londrina, Tijucas do Sul (Tremarin et al 2009b), São José dos Pinhais (Faria et al 2010).…”

Diatom assemblages (Bacillariophyta) in six tropical reservoirs from southeast Brazil: species composition and spatial and temporal variation patterns

“…Ferrari & Ludwig, 2007;Cavalcante et al, 2014;Silva et al, 2016), they are greatly concentrated in the South and Southeast regions of the country (e.g. Moura & Bittencourt-Oliveira, 2004;Bertolli et al, 2010;Faria et al, 2010;Souza-Mosimann et al, 2011;Bes et al, 2012;Bartozek et al, 2013;Nardelli et al, 2014;Marra et al, 2016). Specifically for São Paulo State, studies are mainly a result of the ambientais que melhor explica a variação da composição das espécies entre as unidades amostrais.…”

Eunotia (Bacillariophyceae) from a subtropical stream adjacent to Iguaçu National Park, Brazil, with the proposition of a new species

“…Paraná State citations: Silva-Lehmkuhl et al (2019); cited as E. camelus var. denticulata Grunow in Moreira-Filho & Kutner (1962); cited as E. camelus in Tremarin et al (2009), Bertolli et al (2010), Faria et al (2010, Silva et al (2010), Santos et al (2011), Bartozek et al (2013), Marra et al (2016).…”

“…Eunotia is one of the most common and species-rich diatom genera in the Neotropics (Patrick 1940a, 1940b, Hustedt 1952a, 1952b, 1965, Sala et al 2002a, 2002b, Faustino et al 2016, Costa et al 2017, with remarkable diversity in Brazilian acidic environments (Ferrari et al 2007, Bicca et al 2011, Canani & Torgan 2013, Dunck et al 2013a, 2013b, Cavalcante et al 2014). In the state of Paraná, the genus were reported by Ludwig & Valente-Moreira (1989), Fürstenberger & Valente-Moreira (2000), Tremarin et al (2008), Faria et al (2010), Bertolli et al (2010), Santos et al (2011), Bartozek et al (2013), Marra et al (2016), Silva-Lehmkuhl et al (2019), and Bartozek et al (2020) recently proposed a new species. Based on a bibliographic check-list of freshwater diatom The purpose of the present publication was to investigate the species diversity of Eunotia from a stream located in the surrounding area of the Iguaçu National Park conservation unit.…”
