Tropical cyclone-induced upwelling has an important influence on ocean temperature and chlorophyll-a (Chl-a) concentrations, which are modified by the existence of mesoscale eddies. This paper investigates the regional dynamics and associated variability

Validation and application of the MERIS Terrestrial Chlorophyll Index. [PDF]
Climate is one of the key variables driving ecosystems at local to global scales. How and to what extent vegetation responds to climate variability is a challenging topic for global change analysis.

The estimation of biomass of planktonic algae can be done by two methods, the quantification of geometric biovolume and chlorophyll a. This work which considers as environmental scenario the Ayapel-Cordoba flood-plain lake, introduces (presents) the two

Coral’s susceptibility to bleaching is determined by the strength of the intricate mutual relationships among coral symbionts. However, there is limited knowledge about how the symbiotic members of the scleractinian coral Echinopora gemmacea respond to ...

The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]
The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown

Cloning and characterisation of chlorophyll synthase from Avena sativa [PDF]
The chlorophyll synthase gene from oat (Avena sativa) was cloned and expressed in Escherichia coli. The deduced amino acid sequence consists of 378 amino acids including a presequence, of 46 amino acids.
