Well-drained non-agricultural soils mediate the oxidation of methane directly from the atmosphere, contributing 5 to 10% towards the global methane sink1,2. Studies of methane oxidation kinetics in soil infer the activity of two methanotrophic popula

The fluxes of CH4 and CO2 to the atmosphere, and the relative contributions of ebullition and molecular diffusion, were determined for a small hypertrophic freshwater lake (Priest Pot, UK) over the period May to October 1997. The average total flux o

Estimates ofin situ nitrifying activity have been made in the hypolimnetic water column and surface 1.0 cm of profundal sediments at 2 sites in Grasmere, a mesotrophic lake in the English Lake District. Increases of nitrate concentrations were used t

Oligonucleotide sequences selected from the 16S rRNA genes of various species of ammonia-oxidizing bacteria were evaluated as specific PCR amplification primers and probes. The specificities of primer pairs for eubacterial, Nitrosospira and Nitrosomo

The incidence and diversity of methanogens in Priest Pot, a dynamic and active lake, were monitored by analysing mcrA gene sequences generated from total DNA samples obtained at different times of the year and amplified using the polymerase chain rea

Methane production and methane oxidation potential were measured in a 30 cm peat core from the Moorhouse Nature Reserve, UK. The distribution of known groups of methanogens and methane oxidizing bacteria throughout this peat core was assessed. Using

The autotrophic ammonia-oxidizing bacteria in a eutrophic freshwater lake were studied over a 12-month period. Numbers of ammonia oxidisers in the lakewater were small throughout the year, and tangential-flow concentration was required to obtain mean

Three distinct phases were observed in the change of dissolved inorganic nitrogen concentrations in the hypolimnion of Grasmere. The second phase of decreasing ammonia and increasing nitrate concentrations was typical of the nitrification process. Ob
