Description of methods used for collection/generation of data:" "Samples were taken within 50 m x 50 m plots established at each study site (see Drescher et al., 2016) with minimum distance of 500 m, but usually more than 1 km between plots. Each land-use system was replicated four times resulting in a total of 12 plots (3 land-use systems x 4 replicates). From each plot at each sampling date, one randomly positioned sample was taken resulting in 48 soil cores in total. Each sample measured 16 cm x 16 cm taken to a depth of 5 cm of the mineral soil. Litter and soil were separated in the field and processed separately (96 samples in total). Then, samples were transported to the laboratory for extraction of soil animals. Animals were extracted by heat for 4–8 days until the substrates were completely dry (Kempson et al., 1963) and stored in 70% ethanol until further processing." "Environmental variables were measured in composite samples of each litter and soil (five cores per plot within a radius of ca. 2 m around the soil animal sample), including abiotic factors (pH, water content, C/N ratio) and biotic factors (microbial community composition in litter and soil as indicated by phospholipid fatty acids; Krashevska et al., 2015, V. Krashevska unpubl. data) including the sum of phospholipid fatty acid (PLFA) marker/relative marker lipids of Gram-positive bacteria (i15:0, a15:0, i16:0, i17:0), Gram-negative bacteria (2OH 12:0, 2OH 14:0, 16:1ω7, cy17:0, 2OH 16:0, cy19:0, 2OH 10:0), fungi (18:2ω6,9), algae (20:5ω3), arbuscular mycorrhizal fungi based on the neutral lipid fatty acid (NLFA) 16:1ω5c and root biomass. Litter and soil pH (CaCl2) was measured using a digital pH meter (Greisinger GPHR 1400A, Regenstauf). Aliquots of litter and soil material were dried at 65°C for 72 h, milled and analyzed for total C and N concentrations using an elemental analyzer (Carlo Erba, Milan, Italy). Water content (Wet weight, proportion of dry weight) of litter and soil were determined gravimetrically." "" "Collembola were sorted into morphological groups under a dissecting microscope (Stemi 508, Zeiss, Jena, Germany) at 50x magnification based on basic morphological characters (body shape, morphology of furca, antennae, number of eyes). Several individuals of each morphological group from each sample were subsequently cleared with Nesbitt solution on a heating plate (50⁰C) for 3-10 min. Then, the animals were mounted on slides with Hoyer’s solution (for details see Glime and Wagner, 2017). Collembola were identified to species level using a compound microscope (Axiovert 35, Zeiss) at maximum 400x magnification using the checklist for Indonesian Collembola (Suhardjono et al., 2012) and additional articles containing keys for Collembola of southeast Asia, particularly Indonesia (Potapov and Starostenko, 2002; Potapov, 2012; Mateos and Greenslade, 2015). Due to the poorly described fauna, in many cases we had to assign individuals to morphospecies without Latin binomials (in total 70% of all identified species; deposited in http://ecotaxonomy.org)" "" "2.

Environmental/experimental conditions:" "The study sites were located at a similar altitude of 50 to 100 m a.s.l in area about 80 km in diameter, with the distance between adjacent sites varying between 0.5 and 5 km; for more details see Drescher et al., 2016. Rainforest was included to represent baseline conditions allowing to evaluate changes due to the conversion into agricultural plantations." "Rubber and oil palm plantations were intensively managed monocultures of 10 to 20 and 12 to 19 years, respectively (Drescher et al., 2016). Typically, oil palm plantations were established after clearing and burning of jungle rubber, whereas rubber plantations were established after logging of rainforest (Allen et al., 2015). Soils in the Harapan region mainly comprise loamy Acrisols with low fertility (Allen et al., 2015; Kotowska et al., 2015). Oil palm plantations were fertilized once in the rainy season and once in the dry season with NPK complete fertilizer (i.e., Phonska and Mahkota), potassium chloride (KCl) and urea (CO(NH2)2). Fertilizer addition to oil palm plantations was in the range of 300-550 kg NPK ha-1 y-1 (Allen et al., 2015). Manual and chemical weeding took place throughout the year in both rubber and oil palm plantations. The most commonly used herbicides were glyphosate and paraquat, applied at an average rate of 2-5 L ha-1 y-1 (Allen et al., 2015; Kotowska et al., 2015; Clough et al., 2016)." "" "6.
