However, inherent spatial variability in soil biochemical properties in converted landscapes could be high, and may supersede effects of land-use change on soil nutrient changes. Our aims were to assess changes in soil nutrient stocks with land-use change, and to quantify the proportions of spatial variability and land-use change effects on the overall variance of soil nutrient stocks. This study was conducted in Jambi Province, Sumatra, Indonesia in two distinct landscapes defined by the dominant soil texture and type: loam and clay Acrisol soils. In each landscape, four land-use types were examined: lowland forest and rubber interspersed in naturally regenerating forest (referred here as “jungle rubber”) as reference land uses and smallholder plantations of rubber and oil palm. In the 0–0.5 m soil depth of the reference land uses, the clay Acrisol had higher total N (660.1 ± 63.8–1074.2 ± 158.8 g N m− 2; P ≤ 0.05), exchangeable Ca (24.1 ± 5.7–80.6 ± 22.8 g Ca m− 2; P ≤ 0.06), Mg (4.3 ± 0.6–39.2 ± 16.3 g Mg m− 2; P ≤ 0.02), K (11.7 ± 0.7–34.7 ± 12.1 g K m− 2; P ≤ 0.06), extractable P (1.1 ± 0.1–2.6 ± 0.1 g P m− 2; P ≤ 0.001) and effective cation exchange capacity (ECEC; 11.4 ± 3.1–40.6 ± 11.0 cmolc kg− 1; P = 0.02), illustrating that clay content influenced soil fertility in these highly weathered soils. Compared to the reference land uses, the oil palm plantations had higher soil pH (4.2 ± 0.0–4.6 ± 0.1; P ≤ 0.04), base saturation (8.9 ± 1.6–6.5 ± 1.3%; P ≤ 0.07) and extractable P (0.8 ± 0.1–6.1 ± 3.2 g P m− 2; P ≤ 0.01) in the top 0.5 m depth, which was probably due to the legacy effect of biomass burning and fertilization. We were unable to detect significant effects of land-use change on other soil biochemical characteristics (i.e., ECEC, stocks of exchangeable bases, soil organic carbon (SOC), total N). Based on variance components analysis, a large proportion of the variance of these parameters was accounted by the variation among replicate plots (26–91%) rather than by land-use types (only 0–6%). Power analysis showed that the optimum number of replicate plots to detect land-use change effects on these parameters ranged from 5 to 7. Our results suggest that spatial variability must be represented in the experimental design in order to detect land-use change effects on soil nutrient changes through stratifying the area of inference (i.e., landscape or region) based on known drivers of soil fertility and determining the optimal number of experimental units."],["dc.identifier.doi","10.1016/j.geoderma.2016.08.010"],["dc.identifier.gro","3150168"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6903"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | A | A05: Optimierung des Nährstoffmanagements in Ölpalmplantagen und Hochrechnung plot-basierter Treibhausgasflüsse auf die Landschaftsebene transformierter Regenwälder"],["dc.relation.issn","0016-7061"],["dc.subject","Soil nutrient stocks; Lowland forest; Rubber; Oil palm; Land-use change"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Spatial variability surpasses land-use change effects on soil biochemical properties of converted lowland landscapes in Sumatra, Indonesia"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Yet, it remains unclear how direct and cascading effects of land-use change simultaneously drive ecological shifts. Combining data from a multi-taxon research initiative in Sumatra, Indonesia, we show that direct and cascading land-use effects alter biomass and species richness of taxa across trophic levels ranging from microorganisms to birds. Tropical land use resulted in increases in biomass and species richness via bottom-up cascading effects, but reductions via direct effects. When considering direct and cascading effects together, land use was found to reduce biomass and species richness, with increasing magnitude at higher trophic levels. Our analyses disentangle the multifaceted effects of land-use change on tropical ecosystems, revealing that biotic interactions on broad taxonomic scales influence the ecological outcome of anthropogenic perturbations to natural ecosystems."],["dc.identifier.doi","10.1038/s41559-017-0275-7"],["dc.identifier.pmid","29185508"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13011"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | A | A03: Untersuchung von Land-Atmosphäre Austauschprozesse in Landnutzungsänderungs-Systemen"],["dc.relation","SFB 990 | A | A05: Optimierung des Nährstoffmanagements in Ölpalmplantagen und Hochrechnung plot-basierter Treibhausgasflüsse auf die Landschaftsebene transformierter Regenwälder"],["dc.relation","SFB 990 | B | B01: Structure, stability and functioning of macro-invertebrate communities in rainforest transformation systems in Sumatra (Indonesia)"],["dc.relation","SFB 990 | B | B02: Impact of rainforest transformation on phylogenetic and functional diversity of soil prokaryotic communities in Sumatra (Indonesia)"],["dc.relation","SFB 990 | B | B04: Pflanzenproduktivität und Ressourcenaufteilung im Wurzelraum entlang von Gradienten tropischer Landnutzungsintensität und Baumartenvielfalt"],["dc.relation","SFB 990 | B | B06: Taxonomische, funktionelle, phylogenetische und biogeographische Diversität vaskulärer Pflanzen in Regenwald-Transformationssystemen auf Sumatra (Indonesien)"],["dc.relation","SFB 990 | B | B09: Oberirdische Biodiversitätsmuster und Prozesse in Regenwaldtransformations-Landschaften"],["dc.relation.eissn","2397-334X"],["dc.relation.orgunit","Abteilung Bioklimatologie"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Direct and cascading impacts of tropical land-use change on multi-trophic biodiversity"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
