Environmental dynamics and carbon accumulation rate of a tropical peatland in Central Sumatra, Indonesia

A comparison of satellite remote sensing data fusion methods to map peat swamp forest loss in Sumatra, Indonesia

“…), rubber (Hevea brasiliensis) and coconut (Cocos nucifera). The Sungai Buluh Protection Forest lies in the centre of the study area and is a peat swamp forest with a history of fires and disturbances (Hapsari et al 2017). The forest is about 120 km 2 in size, representing about 4% of the study area.…”

“…The climate in the region is tropical humid, with a mean annual temperature of 26°C and an annual rainfall of 2400 mm (Karger et al 2016). The temperature varies little throughout the year but there is a slightly drier season from June to September, corresponding to the onset of the southeast monsoon (Hapsari et al 2017). However, even during this drier season average monthly precipitation remains above 100 mm, meaning that it is unlikely any seasonality will be seen in the vegetation due to water stress in the drier months.…”

Are secondary forests second-rate? Comparing peatland greenhouse gas emissions, chemical and microbial community properties between primary and secondary forests in Peninsular Malaysia

“…There is a considerable cover of peatlands in the tropics, approximating to 0.25% of land surface area yet accounting for 3% of global soil C or 18% of the total peat C (Hapsari et al, 2017;Hergoualc'h and Verchot, 2014;Strack, 2008). These are most likely an underestimation due to insufficient information on tropical peatlands in general, along with the new discovery of tropical peatlands in Africa (Dargie et al, 2017), and other recent estimates showing increased cover in South America (Gumbricht et al, 2017;Xu et al, 2018).…”

Testing the relationship between testate amoeba community composition and environmental variables in a coastal tropical peatland

“…Multiproxy palaeoenvironmental studies of tropical peatlands are in their infancy (e.g. Hapsari et al, 2017;Swindles et al, 2018), and much uncertainty remains over the efficacy of proxy-based reconstruction methods in these systems. Testate amoebae (TA) are dominant microbial consumers in peatlands, representing up to 30% of the total microbial biomass, and may have a major influence on the ecological functioning of peatland ecosystems through nutrient and carbon cycling (Gilbert et al, 1998;Mitchell et al, 2003).…”
