Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Fluctuating asymmetry based on fractal geometry does not track environmental stress in an intertidal habitat‐forming fucoid

Journal of Phycology, EarlyView.
Abstract The availability of easy‐to‐measure and inexpensive biomarkers is a challenge for monitoring environmental stress in organisms. Although it has been proposed that non‐directional deviations from a symmetrical pattern in morphological traits (called fluctuating asymmetry.

Ariadnema polymorpha gen. et sp. nov. (Scytonemataceae, Cyanobacteria): A new heterocytous cyanobacterium with true and false branching from ruins in the Brazilian Atlantic Forest

Journal of Phycology, EarlyView.
Abstract A novel heterocytous Cyanobacterium, Ariadnema polymorpha gen. et sp. nov., was observed in the northern Brazilian Atlantic Forest (BAF), a globally significant biodiversity hotspot that has microbiome diversity yet to be explored. Isolated from ancient sugarcane mill ruins within the BAF, the new genus (strain CCAPE130) exhibits a unique ...

Euglena sp. and its associated prokaryotic community degrade light crude oil

Journal of Phycology, EarlyView.
Abstract Oil enters the environment through natural and anthropogenic sources and poses a serious threat to water and soil. We hypothesized that algae and their associated prokaryotic communities from natural oil seeps are robust systems capable of surviving and degrading anthropogenic oil spills. We isolated Euglena sp.

Macroalgae respond to consumer‐mediated nutrient cycling in a temperate ecosystem

Journal of Phycology, EarlyView.
Abstract Primary production in coastal upwelling regions has often been presumed to be supported primarily by allochthonous nutrients, but inconsistent nutrient delivery and the metabolic cost of nitrate assimilation can leave producers nitrogen limited during the growing season. As a potential supplement for insufficient allochthonous supply, nutrient

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

Journal of Phycology, EarlyView.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.

Circumscription of three new taxa of Merismopedia‐like Cyanobacteria shows how far convergent evolution can go

Journal of Phycology, EarlyView.
Abstract The genus Merismopedia (Merismopediaceae, Chroococcales), characterized by rectangular colonies with cells arranged in regular perpendicular rows and columns, represents a challenging study system due to its limited cultivability. The genus recently underwent taxonomic revision using cultivation‐independent techniques and a polyphasic approach.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.
