Evolution of soil respiration and its relationship with litter contributions in a wooded mountain soil
Soil respiration (SR) in wooded ecosystems is considered to be the second most important carbon flux between the biosphere and the atmosphere; about half of the SR is derived from metabolic activity, root growth and support, and association with mycorrhizae. In tropical forests, the factor that has...

| Sumario: | Soil respiration (SR) in wooded ecosystems is considered to be the second most important carbon flux between the biosphere and the atmosphere; about half of the SR is derived from metabolic activity, root growth and support, and association with mycorrhizae. In tropical forests, the factor that has the greatest influence on the temporal variation of the SR is not so much the temperature, but rather the water content or the precipitation because the soil temperature is relatively constant. The objective of the work has been to establish the behavior of the SR and to try to estimate and model the ecological process of the SR in the shrubby pre-phase of a mountain forest in the State of Hidalgo, in order to strengthen the theoretical framework of the ecology of restoration and conservation biology, as well as analyzing their relationship with meteorological parameters to understand what are the factors that regulate CO2-soil-atmosphere flows in an annual cycle. Due to the results achieved, it should be pointed out that it will be necessary to carry out a greater number of evaluations in a period of 3 to 5 years and in seasonal periods and periods with a view to reinforcing these results. Three important aspects could be concluded, first that SR is part of the carbon reservoir in forest ecosystems; the soil SR is a variable dependent on time and altitude, at higher time’s higher values of RS and at higher altitudes as well. The daytime breathing rate (TRSD) was found to be slightly higher than the nighttime rate (TRSN), apparently dependent on ambient temperature. It was possible to classify the HA of soils of the forested mountain area of the Chico National Park. It was already reported that they were humic andosol soils, but in this work HA are classified as predominant type A. |
