“…Soil CO 2 is generated by rhizo-microbial respiration and organic matter microbial decomposition, and CO 2 diffusion from the soil to the atmosphere, known as soil CO 2 efflux, is the main carbon output from forest ecosystems (Lopes de Gerenyu et al, 2011;Leon et al, 2014). Soil water content and soil temperature explain around 60% of the spatial and temporal variation in soil CO 2 efflux in most tropical forests (Luo and Zhou, 2006;Vargas and Allen, 2008;Satakhun et al, 2013).…”

“…Soil CO 2 efflux varies seasonally because of changes in soil water content (Kosugi et al, 2007;Katayama et al, 2009), and daily due to diel temperature variation (Vargas, Detto, Baldocchi, and Allen, 2010;Hanpattanakit et al, 2015). Soil topography can be an indirect factor affecting soil CO 2 efflux because of the release of mineral nutrients from upper to lower areas or by flooding in low areas, which limits oxygen diffusivity (Lopes de Gerenyu et al, 2011;Wood, Matthews, Vandecar, and Lawrence, 2016;Cusack et al, 2019).…”

Tropical forest soils store a third of the global terrestrial carbon and control carbon dioxide (CO2) terrestrial effluxes to the atmosphere produced by root and microbial respiration. Soil CO2 efflux varies in time and space and is known to be strongly influenced by soil temperature and water content. However, little is known about the influence of seasonality on soil CO2 efflux, especially in tropical dry forests. This study evaluated soil CO2 efflux, soil temperature, and soil volumetric water content in a semideciduous tropical forest of the Yucatan Peninsula under two sites (flat areas close to and far from hills), and three seasons: dry, wet, and early dry (a transition between the rainy and dry seasons) throughout a year. Additionally, six 24-h periods of soil CO2 efflux were measured within these three seasons. The mean annual soil CO2 efflux was 4±2.2 μmol CO2 m-2 s-1, like the mean soil CO2 efflux during the early dry season. In all seasons, soil CO2 efflux increased linearly with soil moisture, which explained 45% of the spatial-temporal variation of soil CO2 efflux. Soil CO2 efflux was higher close to than far from hills in some months. The daily variation of soil CO2 efflux was less important than its spatial and seasonal variation likely due to small diel variations in temperature. Transition seasons are common in many tropical dry forests, and they should be taken into consideration to have a better understanding of the annual soil CO2 efflux, especially under future climate-change scenarios.

The effects of topographic variables (elevation above sea level, slope position, topographic (wetness) index, and global solar radiation) on mite abundances and on quantitative composition of Oribatida communities in soil and litter have been studied in six sites along a hill slope in a tropical lowland forest in the Bu Gia Map National Park, Southern Vietnam. A positive relationship existed between abundance and species richness of Oribatida in soil cores, and global solar radiation (W h m(-2)) which quantifies the total sun energy available to the local ecosystem. There was no significant relationship between abundance of Mesostigmata and topographic variables. The Oribatida community composition in soil and in litter was significantly different, with a large number of species unique to either litter or soil. The canonical correspondence analysis (CCA) showed that the topographic variables together explained 75% (in litter) and 83% (in soil) of the variation in Oribatida community structure. The species-topography relationship was globally significant in the litter, weaker in the soil; the eigenvalue of the CCA axis 1 (related to elevation and global solar radiation) was significant in both substrates. CCA ordinations identified groups of species associated with high landscape positions (hill crest, high elevation, high global solar radiation) versus species associated with low-lying landscape positions, where moisture tends to accumulate (hill footslope, low elevation, low solar radiation, high topographic index values). The importance of relief and geographical position for soil Oribatida is discussed.
