microbes, collectively termed phytoplankton, are responsible for the vast majority of primary …

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized
by the misfolding and aggregation of distinct proteins in affected tissues, however, the …

Iron supply has been suggested to influence phytoplankton biomass, growth rate and species
composition, as well as primary productivity in both high and low NO 3 − surface waters. …

Background The effect of personalised mechanical ventilation on clinical outcomes in
patients with acute respiratory distress syndrome (ARDS) remains uncertain and needs to be …

Diatoms are photosynthetic secondary endosymbionts found throughout marine and
freshwater environments, and are believed to be responsible for around one-fifth of the primary …

A compilation of data on the elemental composition of marine phytoplankton from published
studies was used to determine the range of C[ratio ]N[ratio ]P. The N[ratio ]P ratio of algae …

The role of iron in enhancing phytoplankton productivity in high nutrient, low chlorophyll
oceanic regions was demonstrated first through iron-addition bioassay experiments 1 and …

The effects of nitrate, phosphate, and iron starvation and resupply on photosynthetic
pigments, selected photosynthetic proteins, and photosystem II (PSII) photochemistry were …

… Julie La Roche describes the need to establish a hierarchy of controls by N, P, Si and Fe

The diadinoxanthin cycle (DD-cycle) in chromophyte algae involves the interconversion of
two carotenoids, diadinoxanthin (DD) and diatoxanthin (DT). We investigated the kinetics of …
