Another way to collect a stool sample is to loosely place plastic wrap across the rim of the toilet, under the seat. Then place the stool sample in a clean, sealable container before taking to the laboratory. Plastic wrap can also be used to line the diaper of an infant or toddler who is not yet using the toilet. The stool should be collected into clean, dry plastic jars with screw-cap lids.
Effects of rising temperatures. Increased soil respiration â Rising temperature increases the rate of chemical and biochemical reactions. For soil microbes and roots, that also means increasing respiration, which can release more carbon dioxide and even methane from soils.
The present study tested the following hypotheses: (i) land use change alters the concentration of soil microbial biomass carbon (C) and nitrogen (N) at different soil depths; (ii) seasonal variations in the concentration of soil microbial biomass C and N are regulated by climatic factors and land-use types; (iii) shifting of microbial community structure in terms of microbial biomass C/N ratio occurs with the land-use change and soil depth; and (iv) restoration of degraded lands can be ...
