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.
Global warming affects evapotranspirationâthe movement of water into the atmosphere from land and water surfaces and plants due to evaporation and transpirationâ which is expected to lead to: Increased drought in dry areas. In drier regions, evapotranspiration may produce periods of droughtâdefined as below-normal levels of rivers, lakes, and groundwater, and lack of enough soil moisture in agricultural areas. Precipitation has declined in the tropics and subtropics since 1970.
