Epitypification of Merismopedia tranquilla (Cyanobacteria) prompts phylogenetic reassessment of the genus and the description of two morphologically similar genera

open access: yesJournal of Phycology, EarlyView.
Abstract The genus Merismopedia is morphologically characterized by its distinctive colony arrangement yet exhibits considerable variability among species. Recent studies suggested that Merismopedia is polyphyletic, and its most likely true lineage was provisionally placed within the Microcystaceae. However, the available molecular data for most of the

Effects of sedimentation and periphyton communities on embryonic rainbow smelt, Osmerus mordax [PDF]

open access: yes, 2009
The decline of anadromous rainbow smelt (Osmerus mordax) populations has been suspected to be linked to anthropogenic causes. Increased runoff from agriculture and urbanization has led to additional sediment inputs and eutrophying compounds in rivers ...

How do I publish the name of a new species of algae? A basic guide

open access: yesJournal of Phycology, EarlyView.
Abstract A basic guide to the requirements of the International Code of Nomenclature for algae, fungi, and plants for the publication of a valid name of new species (and infraspecific taxa) of living algae is provided. It is intended to aid phycologists so that an accurate inventory of the world's algal diversity is achieved.

The Potential Use of Marine Microalgae and Cyanobacteria in Cosmetics and Thalassotherapy

open access: yesCosmetics, 2017
The use of microalgae and cyanobacteria for nutritional purposes dates back thousands of years; during the last few decades, microalgae culture has improved to become one of the modern biotechnologies. This has allowed high amounts of algal biomass to be

Photophysiological and photosynthetic complex changes during iron starvation in Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942

open access: yes, 2013
Iron is an essential component in many protein complexes involved in photosynthesis, but environmental iron availability is often low as oxidized forms of iron are insoluble in water.

Dominance and toxicity without lethality: Exploring biomass, cyanometabolites, and Daphnia responses across Cyanobacterial strains

open access: yesJournal of Phycology, EarlyView.
Abstract Cyanobacteria are cosmopolitan, important components of biomass with a remarkable ability to synthesize a diverse array of bioactive compounds, some of which may have toxic effects on other organisms and ecosystems. In this study, filamentous cyanobacterial strains isolated predominantly from temperate European freshwaters (Aphanizomenon ...

Chemoecological Screening Reveals High Bioactivity in Diverse Culturable Portuguese Marine Cyanobacteria

open access: yesMarine Drugs, 2013
Marine cyanobacteria, notably those from tropical regions, are a rich source of bioactive secondary metabolites. Tropical marine cyanobacteria often grow to high densities in the environment, allowing direct isolation of many secondary metabolites from ...

Genomic and secondary metabolites of the marine cyanobacterium Capilliphycus salinus ALCB114379

open access: yesJournal of Phycology, EarlyView.
Abstract Assembling high‐quality genomes from underexplored environments can be helpful for understanding microbial diversity and identifying novel species. The Cyanobacterium type strain Capilliphycus salinus ALCB114379 is a representative of Oscillatoriales order isolated from a supralittoral zone of the south Atlantic Ocean in Brazil, an ecotone ...
