Inorganic and organic carbon biogeochemistry in the Gautami Godavari estuary (Andhra Pradesh, India) during pre‐monsoon: The local impact of extensive mangrove forests
The distribution and sources of organic and inorganic carbon were studied in the Gautami Godavari estuary (Andhra Pradesh, India) and in a mangrove ecosystem in its delta during pre‐monsoon. In the
Summary Transects across six kelp beds located between Cape Agulhas and Saldanha Bay are surveyed and the fauna and flora quantified in terms of energy units. Numerical analysis and information
Dynamics of organic and inorganic carbon across contiguous mangrove and seagrass systems (Gazi Bay, Kenya)
forest and the dense seagrass beds. The latter is consistent with the reported export of mangrove-derived material, which is efficiently trapped in the adjacent seagrass beds. There were significant
How many damaged corals in Red Sea reef systems? A quantitative survey
Quantitative coral damage assessment by means of line transects was performed in several northern Red Sea coral reef sites in Israel and Egypt, finding breakage was found to be the most common damage category, being significantly higher on highly frequented reefs.
High control of bacterial production by viruses in a eutrophic oxbow lake
It is demonstrated that viruses could control more than 100% of the bacterial production in the Alte Donau, which implies that occasionally up to 1.6% h -1 of the standing stock was removed from the water column, indicating that a large amount of dissolved organic carbon might be recycled from bacteria by phage- induced cell lysis.
Viriobenthos in freshwater and marine sediments : a review
First results from a few studies using pulsed-field gel electrophoresis and especially from metagenomic analyses indicate, however, that viriobenthic assemblages are both highly diverse and distinct from the virioplankton.
Nanobacteria, Ultramicrobacteria and Starvation Forms : A Search for the Smallest Metabolizing Bacterium
It could be shown that despite conceptual shortcomings and problems with definitions of what is meant by "small", starvation forms and ultramicrobacteria are clearly distinguishable according to physiological characteristics, which could not be achieved for nanobacteria or nanobes.
Erythrobacter citreus sp. nov., a yellow-pigmented bacterium that lacks bacteriochlorophyll a, isolated from the western Mediterranean Sea.
Two facultatively oligotrophic, intensely yellow-pigmented bacterial strains have been previously isolated from the western Mediterranean Sea and DNA-DNA reassociation studies confirmed that strains RE35F/1T and RE10F/45 represent a single species, but demonstrated that they do not belong to the species Erythrobacter litoralis.
Microheterotrophic utilization of mucus released by the Mediterranean coral Cladocora cespitosa
The carbon conversion efficiency of 20% obtained from the bacterial population during decomposition of mucus indicates the high nutritional value of C. cespitosa mucus, although bacterial carbon onto mucus particles contributes less than 0.1% to the total organic carbon pool of the mucus.
Seasonal variations of virus abundance and viral control of the bacterial production in a backwater system of the danube river
The data on virus-induced bacterial mortality obtained by both the viral decay method and the determination of the frequency of infected cells are compared and discussed.
