I want to find relationship between mangrove mollusc and selected environment parameters (soil temperature, soil salinity, soil pH). I found some articles include DO also. But how can I measure DO in soil (especially during dry season)? and plus I take my sample during low tide. Can I just omit this parameter?
You might look at Burgin and Groffman (2012) for an example of soil O2 sensors that were deployed in a wetland soil for several months. Hope this helps.
Burgin, A. J., and P. M. Groffman (2012), Soil O2 controls denitrification rates and N2O yield in a riparian wetland, J. Geophys. Res., 117, G01010, doi:10.1029/2011JG001799.
You might also consider using redox potential as a proxy for oxygen; at the moment Eh is much easier and cheaper to measure in soils/sediments.
The term DO (I mean dissolved) in soil is not correct, I think. For measuring oxygen in soil, probes are available. However the parameter has hardly any impact on molluscan community
