In complex tropical agroecosystems such as agroforests, management determines plant architecture, vegetation composition and associated ant density, but little is known on how these attributes, together with landscape context, determine spider web density. We hypothesized that all three spatial scales and the presence of Philidris ants significantly contribute to the explanation of spider web density with web types being differently affected.Location  In 42 differently managed cacao agroforestry systems in Sulawesi, Indonesia.Methods  We surveyed the distribution of five spider-web types on 420 cacao trees to determine how these relate to habitat variables and a numerically dominant ant species at three different spatial scales, comparing tree, plot and landscape features. We fitted linear mixed-effects model, selected the best model subset using information-theoretic criteria and calculated the model-averaged estimates. We used non-metric multidimensional scaling (NMDS) to determine and visualize guild level responses to the effects of the tree, plot and landscape-scale variables.Results  The five spider guilds preferred different features of cacao tree architecture. Most frequently recorded webs belonged to the line- and orb-web type. At the tree scale, overall web density was positively related to canopy openness. At the plot scale, a higher number of shade trees was related to a higher web density. At the landscape scale, the altitude determined the distribution patterns of web-building spiders. Presence of Philidris ants was positively associated with density of orb webs, while no pattern was found for other web types.Main conclusions  Results suggest spider web density could be increased by pruning of cacao trees while keeping shade trees at high density in cacao plots. The results emphasize the need to consider scale dependency of crop management and web-guild-specific responses that may be related to different functional roles of spiders as a high-density predator group in agroforestry."],["dc.identifier.doi","10.1111/j.1472-4642.2011.00774.x"],["dc.identifier.gro","3150065"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6792"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation.issn","1366-9516"],["dc.title","Spider web guilds in cacao agroforestry - comparing tree, plot and landscape-scale management"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Controversially discussed solutions include wildlife-friendly farming or combining high-intensity farming with land-sparing for nature. Here, we integrate biodiversity and crop productivity data for smallholder cacao in Indonesia to exemplify for tropical agroforests that there is little relationship between yield and biodiversity under current management, opening substantial opportunities for wildlife-friendly management. Species richness of trees, fungi, invertebrates, and vertebrates did not decrease with yield. Moderate shade, adequate labor, and input level can be combined with a complex habitat structure to provide high biodiversity as well as high yields.

Understanding how these processes affect ecosystems and their functioning, in particular in the high-diversity ecosystems of the tropics, has become a key issue in ecological research. In this chapter, our focus is on the agriculture-forest landscapes of Central Sulawesi, Indonesia, an island widely known for its endemic yet still poorly known flora and fauna. The rise of the region to one of the largest cacao producing areas in the world is at the core of recent land-use change and intensification processes. Covering plants (trees, rattan palms, herbs, bryophytes) and several invertebrate (ants, dung beetles, cacao insect herbivores, fruit-feeding butterflies, parasitic Hymenoptera, spiders) and vertebrate groups (amphibians, birds, murids, reptiles), we give an in-depth overview of the determinants of biodiversity in cacao landscapes, including both management and landscape-scale variables into our analyses. Results show that shaded agroforests host a rich community of species. By adopting a large-scale study design we showed that proximity of natural forest is a key predictor for species richness of plants, invertebrates and vertebrates alike. Endemics and forest specialists benefit most from indigenous shade tree cover and proximity to natural forest. Importantly, several functionally important groups such as insectivorous and seed-dispersing birds benefit from tall shade trees, shade tree diversity and proximity to forest edge, while parasitoid diversity is greatest close to natural forests. Available data on the effects of landuse change in cacao landscape of Central Sulawesi is increasing. Change in landscape configuration and management practices are being clearly reflected in the composition of species communities, with likely impacts on ecosystem services such as pest control and pollination. More knowledge is needed especially in terms of species interactions and ecosystem functioning, but also on how existing knowledge can contribute to effective conservation in human-dominated landscapes outside protected areas."],["dc.identifier.doi","10.1007/978-3-642-00493-3_2"],["dc.identifier.gro","3150103"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6834"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.publisher","Springer"],["dc.publisher.place","Berlin, Heidelberg"],["dc.relation.isbn","978-3-642-00492-6"],["dc.relation.ispartof","Tropical Rainforests and Agroforests under Global Change: Ecological and Socio-economic Valuations"],["dc.relation.issn","1863-5520"],["dc.title","Biodiversity patterns and trophic interactions in human-dominated tropical landscapes in Sulawesi (Indonesia): plants, arthropods and vertebrates"],["dc.type","book_chapter"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Here, we use data from twelve differently managed cocoa agroforestry systems in Indonesia to investigate the abundance, diversity and composition of spider communities at three spatial scales: (i) stratum, i.e. litter, herb and cocoa canopy layer, (ii) plot-level shade, litter and weed management and (iii) landscape context, i.e. distance to natural forest. Spider communities of all three strata were positively affected by herb cover. High cocoa leaf litter density, which characterised high-intensity management, was accompanied by a decrease in spider abundance and species richness. On a community level, we did not find an effect of forest edge proximity on spider abundance or species richness, but with distance to forest a shift of species dominance in favour of generalists. Our results showed an impact of all three spatial scales, from the microhabitat and local plot management to the landscape context, which changed spider community composition, and suggest a focus beyond plot-level shade management to understand determinants of spider community in cocoa agroforestry systems."],["dc.identifier.doi","10.1016/j.agee.2011.03.021"],["dc.identifier.gro","3150034"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6757"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation.issn","0167-8809"],["dc.title","Spider species richness in cocoa agroforestry systems, comparing vertical strata, local management and distance to forest"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
