Periphytic Actinella Lewis (Ochrophyta, Bacillariophyceae) Species From an Environmental Protection Area in the Brazilian Amazon [PDF]
Acta Limnologica Brasiliensia, 2018 Abstract Aim The aim of this study is to present the Actinella species found in periphytic samples collected from an Environmental Protection Area in Santarém (PA, Brazil), to comment on their morphology by comparing them with existing records, and to increase knowledge of the distribution of the genus in Pará State. Methods Ten periphytic samples were

A New Actinella Species (Eunotiaceae, Bacillariophyta) From the Yangambi Biosphere Reserve, Democratic Republic of the Congo [PDF]
Plant Ecology and EvolutionBackground and aims – Actinella species from Central Africa are only rarely reported. The acid waters from many stream and small rivers in the Congo Basin form a potential environment for species of this genus. We studied several samples from the region of Yangambi to confirm whether species belonging to this genus are present.

Actinella Species (Bacillariophyta) From an Amazon Black Water Floodplain Lake (Amazonas - Brazil) [PDF]
Acta Amazonica, 2010 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).

DIATOMOFLíâ??RULA PERIF TICA DE ALGUMAS LOCALIDADES DA BACIA HIDROGRÁFICA DO RIO DESCOBERTO, DISTRITO FEDERAL E GOIÁS, BRASIL, EUNOTIALES (BACILLARIOPHYCEAE): Actinella e Peronia [PDF]
Heringeriana, 2017 No Distrito Federal e em Goiás, estudos taxonômicos das Bacillariophyta são escassos. Este trabalho apresenta o levantamento taxonômico das diatomáceas pertencentes aos gêneros Actinella e Peronia do rio Descoberto e alguns de seus afluentes. As coletas foram realizadas em junho e julho de 2003 (período de seca) e janeiro e fevereiro de 2004 (período

FotteaAbstract: The taxonomic concept of Actinella guianensis Grunow is well-established in the literature. However, during the analysis of recent samples from two Amazon blackwater habitats, we found an uncommon and oddly shaped Actinella taxon, which corresponds to what is reported in Grunow's drawings in Van Heurck's Atlas as the type species of A ...

Plant Ecology and Evolution, 2010 Background and aims – The majority of freshwater diatom lineages appear to have evolved before or during the Eocene, with rapid radiation occurring in the Miocene. However, only a few accurately dated fossil localities are available to test this assertion, resulting in an overall poor understanding of the biostratigraphy and early evolution of these ...

Cladistics, Volume 36, Issue 6, Page 594-616, December 2020., 2020 Abstract The Geomitrini is the most species‐rich group of land snails in the Madeiran Archipelago. The phylogeny of the group is reconstructed based on mitochondrial and nuclear genetic markers. The timing of diversification, the colonisation history of the islands of the Madeiran Archipelago and the evolution of characters of the dart apparatus are ...
