Abstract: Tropical deforestation for the establishment of tree cash crop plantations causes significant alterations to soil organic carbon (SOC) dynamics. Despite this recognition, the current Intergovernmental Panel on Climate Change (IPCC) tier 1 method has a SOC change factor of 1 (no SOC loss) for conversion of forests to perennial tree crops, because of scarcity of SOC data. In this pantropic study, conducted in active deforestation regions of Indonesia, Cameroon, and Peru, we quantified the impact of forest conver… Show more

“…In the synthesis of paired‐site experiments, Liao, Luo, Fang, and Li () found that fine root biomass decreased by up to 66% in broad‐leaved and coniferous plantations compared with natural forests. Our results were also in accordance with other studies that suggested that afforestation with coniferous tree species could lead to increasing C in the litter (Vesterdal, Clarke, Sigurdsson, & Gundersen, ) and decreasing fine roots and soil C pools (van Straaten et al, ). In this study, soil C pools in the larch plantations have not been restored to the original level in paired‐site secondary forests 40–45 years after the forest cover change.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…This finding is in line with those previously found in a Brazilian study, where SOC losses were more pronounced for OP plantations derived from pasture than from forested areas (17). However, the proportion of initial SOC lost in this study (39%) was similar to the proportion reported for rainforest-derived plantations, with the difference that it took longer to reach a new equilibrium in the pasture-derived plantations (20).…”

“…Our observations are specific to the sites we visited in Kerinci Regency, Sumatera, Indonesia, and should not be extrapolated beyond this region. However, our finding that land use change ultimately reduces soil SOC stocks in the long term (Figure 3) is in accordance with several studies on carbon stocks that report SOC losses after land uses conversion from primary forest to agricultural land (Don et al, 2011; Filho et al, 2013; Lal, 2018; van Straaten et al, 2015). The decrease in bulk density observed after conversion from forest to cinnamon plantation not only directly influences the calculation of SOC stocks.…”
