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.

Chemoecological Screening Reveals High Bioactivity in Diverse Culturable Portuguese Marine Cyanobacteria

Marine 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 ...

Correlations Between a Cyanobacteria Bloom's Decline and Environmental Dynamics. [PDF]

, 2009
Lake Kainui is an ombrogenous peat lake that is eutrophic and has frequent cyanobacterial blooms. This research aimed to elucidate the factors that correlated with cyanobacterial bloom decline in Lake Kainui. Abiotic and biotic variables in Lake Kainui

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

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.

Anoxia-adapted cyanobacteria in a marine blue hole

Applied and Environmental Microbiology
Vertical transmission of marine particles brings ocean surface cyanobacteria into the deep ocean, where heterotrophic cyanobacterial lineages probably evolve to adapt to new environments even in oxygen-depleted zones.

Cyanobactins from Cyanobacteria: Current Genetic and Chemical State of Knowledge

Marine Drugs, 2015
Cyanobacteria are considered to be one of the most promising sources of new, natural products. Apart from non-ribosomal peptides and polyketides, ribosomally synthesized and post-translationally modified peptides (RiPPs) are one of the leading groups of ...

Recent occurrence of Cylindrospermopsis raciborskii, in Waikato lakes of New Zealand. [PDF]

, 2003
Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth ≤5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand.

Extending the Farquhar–von Caemmerer–Berry photosynthesis model to account for various photorespiratory bypasses

New Phytologist, EarlyView.
We extend a widely used C3‐photosynthesis model to account for various photorespiratory bypasses, thereby, providing a useful resource and framework that enforces future novel bypass work and scrutinize if the results go counter to theory. Our model analyses show that of the 17 published bypass pathways, full‐decarboxylating bypasses (that have been ...
