Data from: Effects of tree functional traits on soil respiration in tropical forest plantations
<p>The study covers four plantations stands of Acacia auriculiformis (A), Eucalyptus urophylla (E), Hopea odorata (H), and X. xylocarpa (X) through a sample plot (50 m x 50 m) in each stand from July 2015 until June 2016. Physical and chemical soil properties were collected at two depths (0-15 cm, 15-30 cm) at the beginning of the study (soil_properties_initial.csv). Additional samplings of topsoil pH, bulk density (BD, g cm-3), organic matter (OM, %), total carbon (TC, %), and nitrogen (TN, %) were conducted monthly (mo_yr) at five random locations (soil_properties_month.csv). Soil respiration (SR) was measured at the beginning of each month (mo_yr) at 12 locations (Point) within each species sample plot (Species) for ten hours (h_time) simultaneously with soil temperature (ST, C), air temperature (AT, C), relative humidity (RH), and soil moisture (SM, %) (soil_respiration.csv). The location of each soil respiration measurement point within the sample plots is provided as well (soil_respiration_location.csv). All trees within each sample plot were mapped (X, Y) and their stem basal area (BA_cm2) and height (H) were measured (stand_inventories.csv).</p>
Drivers of soil organic carbon stock during tropical forest succession
<p>Soil organic matter contributes to productivity in terrestrial ecosystems and contains more carbon than is found in the atmosphere. Yet, there is little understanding of soil organic carbon (SOC) sequestration processes during tropical forest succession, particularly after land abandonment from agriculture practices.</p> <p>Here we used vegetation and environmental data from two large-scale surveys covering a total landscape area of 20,000 ha in Southeast Asia to investigate the effects of plant species diversity, functional trait diversity, phylogenetic diversity, aboveground biomass, and environmental factors on SOC sequestration during forest succession.</p> <p>We found that functional trait diversity plays an important role in determining SOC sequestration across successional trajectories. Increases in SOC carbon storage were associated with indirect positive effects of species diversity and succession age <em>via</em> functional trait diversity, but phylogenetic diversity and aboveground biomass showed no significant relationship with SOC stock. Furthermore, the effects of soil properties and functional trait diversity on SOC carbon storage shift across elevation.</p> <p>Synthesis: Our results suggest that reforestation and restoration management practices that implement a trait-based approach by combining long-lived and short-lived species (conservative and acquisitive traits) to increase plant functional diversity could enhance SOC sequestration for climate change mitigation and adaptation efforts, as well as accelerate recovery of healthy soils.</p>
