No published reports exist on the early stages in the establishment and succession of microbial communities and associated chemical and geochemical transformations in aquatic environments shortly after a volcanic event. Much of our understanding of volcanic lakes has come from studies carried out years to centuries after the eruption, when the lakes were already stabilized. Here we document the chemical and microbiological responses of lakes and hydrothermal environments in the blast zone near…

This review of papers reporting the effects of volcanic eruptions in freshwater environments and on freshwater organisms finds an increase in water turbidity is the most common reported physical effect while increases in concentrations of inorganic elements, many representing nutrients for primary producers, are the mostCommon chemical effects.

Within 15 months or less of the eruption, algal communities were established throughout the blast impact area, but as a result of the initial and continued disturbance these communities remained in an early successional stage.

Denitrification, Acetylene Reduction, and Methane Metabolism in Lake Sediment Exposed to Acetylene
- ChemistryApplied and environmental microbiology

Samples of sediment from Lake St. George, Ontario, Canada, were incubated in the laboratory under an initially aerobic gas phase and under anaerobic conditions and there was O(2)-dependent production of nitrous oxide, which was inhibited by acetylene and by nitrapyrin, suggesting that coupled nitrification-denitrification was responsible.

Long-term exposure was necessary before a reduction in nitrogen fixation rates was observed; unamended rates of denitrification but not potential denitrified rates (NO(3) added) were depressed after exposure to hydrocarbons.
Nitrogen Fixation in a Salt Marsh
- Environmental Science
- 1974
The lower zones of salt marshes, in common with most marine habitats, are deficient in available combined nitrogen and therefore any contribution made by nitrogenfixing organisms to the nitrogen status of the marsh is likely to be significant.

Oxygen was found to exert little effect on the observed acetylene reduction activity, indicating that stable aerobic and anaerobic microenvironments exist in the surface layer of marsh sediments.
