Basicladia emedii (Cladophorales, Chlorophyta): a new freshwater epilithic species from Brazil
(Adac-cryptogamie, 2012-11-01)
Basicladia emedii sp. nov. is described based on material from six streams in Parana and Rio Grande do Sul States of Brazil. This is only the second species of Basicladia recorded from South America. The new species is ...

Las cianobacterias como indicadores de contaminación orgánica
(Universidad de Costa Rica, 1999)
Assessment of the potential toxicity of glyphosate-based herbicides on the photosynthesis of Nitella microcarpa var. wrightii (Charophyceae)
(2016-01-01)
Although macroalgae are considered one of the most important primary producers in streams, to our knowledge there has been no research on the effects of herbicides on these organisms. Such studies are crucial for improving ...
Bioactive compounds against neglected diseases isolated from macroalgae: a review
(2018-01-01)
To survive in a very competitive environment, marine macroalgae had to evolve defense strategies, resulting in an enormous diversity of compounds from different metabolic pathways. These secondary metabolites have been ...
A highly accurate level set approach for segmenting green microalgae images
(Universidade Federal da Bahia - UFBAIntelligent Vision Research Lab – iVisionSalvador, 2015-08)
We present a method for segmenting 2D microscopy images of freshwater green microalgae. Our approach is based on a specialized level set method, leading to efficient and highly accurate algae segmentation. The level set ...
Diversity of Sulfated Polysaccharides From Cell Walls of Coenocytic Green Algae and Their Structural Relationships in View of Green Algal Evolution
(Frontiers Media, 2020-09)
Seaweeds biosynthesize sulfated polysaccharides as key components of their cell walls. These polysaccharides are potentially interesting as biologically active compounds. Green macroalgae of the class Ulvophyceae comprise ...
“Algae's sulfated polysaccharides modifications: Potential use of microbial enzymes”
(2016-08-01)
Marine algae are valuable sources of structurally diverse bioactive compounds, among them, the group of sulfated polysaccharides (SPs). As an example of SPs, it could be cited the fucoidans in brown algae, carrageenans in ...
Canopy cover as the key factor for occurrence and species richness of subtropical stream green algae (Chlorophyta)
(2017-01-01)
Understanding how local and regional environmental factors influence species richness remains a key issue in ecology. Green algae (Chlorophyta) are a diverse and widely occurring group, which may be a good model for studying ...
