An annotated checklist of the Arcella (Arcellidae) from littoral zone of Paranoá lake-Brazil, with a pictorial key

open access: yesActa Scientiarum: Biological Sciences, 2016
The pictorial key contributes to taxonomic analysis, as it lists the species found in a given environment, and points out the morphological characteristics that differs one specific taxon from the others.

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

open access: yesPest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

Sinks and Sources of Intracellular Nitrate in Gromiids

open access: yesFrontiers in Microbiology, 2017
A substantial nitrate pool is stored within living cells in various benthic marine environments. The fate of this bioavailable nitrogen differs according to the organisms managing the intracellular nitrate (ICN).

Decreased DMI sensitivity of Plenodomus biglobosus (phoma of oilseed rape) associated with CYP51 substitution G476S

open access: yesPest Management Science, EarlyView.
Here, we report for the first time a target site mutation in the CYP51 gene of the oilseed rape phoma stem canker fungus Plenodomus biglobosus (Leptosphaeria biglobosa) that is associated with decreased sensitivity to sterol demethylation inhibitor fungicides.

The words ‘protist’ and ‘protista’ [PDF]

open access: yesExperientia, 1958
Les auteurs estiment que l'on devrait employer les mots «Protiste» et «Protista» a peu pres dans le sens originel deHaeckel (1866) — c'est-a-dire pour l'ensemble Bacteries, Algues, Champignons, et Protozoaires — et ne pas en exclure ni les Bacteries ni les Algues bleuesvertes comme l'a faitCopeland en 1938.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Investigation of protists in Momoge wetland (China) through metagenomic next-generation sequencing [PDF]

open access: yesBiodiversity Data Journal
The Momoge wetland plays an important role in maintaining the ecosphere and protist is an indispensable component of it. In order to reveal community structure and diversity of protists in Momoge wetland, metagenomic next-generation sequencing (mNGS) was
