Actinella species (Bacillariophyta) from an Amazon black water floodplain lake (Amazonas - Brazil)

The genus Actinella Lewis was studied using planktonic samples from a black water floodplain lake in Central Amazon region. For species identification the taxa were morphological and morphometricaly analyzed on base in light microscope (LM) and scanning electronic microscope (SEM). Five species were...

For species identification the taxa were morphological and morphometricaly analyzed on base in light microscope (LM) and scanning electronic microscope (SEM). Five species were registeredActinella brasiliensis Grunow, A. guianensis Grunow, A. gracile Kociolek, A. mirabilis (Eulenstein ex Grunow) Grunow and A. robusta Hustedt. A. gracile is reported for the first time for Amazon State and black water systems and it is firstly documented with SEM.

O gênero Actinella Lewis foi estudado a partir de amostras coletadas em um lago de inundação de águas pretas na Amazônia Central. Para a identificação das espécies as características morfológicas e morfométricas dos táxons foram analisadas em microscopia óptica (MO) e eletrônica de varredura (MEV). Cinco espécies foram identificadas: Actinella brasiliensis Grunow, A. guianensis Grunow, A. gracile Kociolek, A. mirabilis (Eulenstein ex Grunow) Grunow e A. robusta Hustedt. A. gracile é referida pela primeira vez para o estado do Amazonas e para ambientes de águas pretas, sendo documentada pela primeira vez em MEV. Em adição, uma revisão sobre a distribuição geográfica das espécies de Actinella na região da Amazônia brasileira é apresentada. 2020-04-24T15:13:48Z 2020-04-24T15:13:48Z 2010 Artigo https://repositorio.inpa.gov.br/handle/1/13047 10.1590/S0044-59672010000200004 en Volume 40, Número 2, Pags. 269-274 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica
