Potentially, ecosystems show nonlinear responses to land-use intensification that would open management options with limited ecological losses but satisfying economic gains. However, multidisciplinary studies to quantify ecological losses and socioeconomic tradeoffs under different management options are rare. Here, we evaluate opposing land use strategies in cacao agroforestry in Sulawesi, Indonesia, by using data on species richness of nine plant and animal taxa, six related ecosystem functions, and on socioeconomic drivers of agroforestry expansion. Expansion of cacao cultivation by 230% in the last two decades was triggered not only by economic market mechanisms, but also by rarely considered cultural factors. Transformation from near-primary forest to agroforestry had little effect on overall species richness, but reduced plant biomass and carbon storage by ≈75% and species richness of forest-using species by ≈60%. In contrast, increased land use intensity in cacao agroforestry, coupled with a reduction in shade tree cover from 80% to 40%, caused only minor quantitative changes in biodiversity and maintained high levels of ecosystem functioning while doubling farmers' net income. However, unshaded systems further increased income by ≈40%, implying that current economic incentives and cultural preferences for new intensification practices put shaded systems at risk. We conclude that low-shade agroforestry provides the best available compromise between economic forces and ecological needs. Certification schemes for shade-grown crops may provide a market-based mechanism to slow down current intensification trends."],["dc.identifier.doi","10.1073/pnas.0608409104"],["dc.identifier.gro","3148984"],["dc.identifier.scopus","2-s2.0-34247633507"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5623"],["dc.identifier.url","http://www.scopus.com/inward/record.url?eid=2-s2.0-34247633507&partnerID=MN8TOARS"],["dc.language.iso","en"],["dc.notes.intern","Faust Crossref Import"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.eissn","1091-6490"],["dc.relation.issn","0027-8424"],["dc.title","Tradeoffs between income, biodiversity, and ecosystem functioning during tropical rainforest conversion and agroforestry intensification"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Currently, beech is being replanted and an increasing proportion of German forests are mixed stands. Focusing on the reaction of the soil fauna to forest conversion, this study investigates the response of the Collembola community to replacement of beech by spruce or by mixed stands of beech and spruce. Stands of different age were investigated in a factorial design with the factors stand type (beech, spruce and mixed stands) and stand age (30 and 120 years). Cottembola communities did not differ strongly between stand types and stand age and were dominated by Folsomia quadrioculata and Mesaphorura species (e.g. Mesaphorura macrochaeta). Moreover, neither total abundance of Collembota nor densities of the fungal feeding euedaphic Onychiurinae and Tullbergiinae significantly responded to stand type and stand age. The density of the epedaphic and partly herbivorous groups Symphypteona/Neelipleona and Entomobryidae in the 120-year-old stands significantly exceeded that in the 30-year-old stands; presumably, this was due to the well developed herb layer in the 120-year-old stands with more open canopies. Canonical correspondence analysis (CCA) of the Collembota community of the L/F horizon also indicated that most of the epigeic species were associated with the 120-year-old stands. Moreover, the diversity of Collembota significantly increased with forest age which likely reflects increased amount and diversity of food resources in the 120-year-old stands. The density of the hygrophilous species Fo. quadrioculata was significantly higher in the spruce than in the beech stands; probably this was due to the higher water content in litter of the spruce stands. Moreover, the results of the CCAs indicated that soil pH is an important structuring force for the Collembola communities. Overall, the results suggest that stand type and forest age impact Collembola communities, presumably via changes in the amount and quality of food resources, such as living plant and herb litter materials. The pronounced changes which occurred with forest age likely were related to the development of more dense and diverse herb layer in mature forests which provides additional food resources in particular for epedaphic species. On the other hand, dominant species/functional groups of Collembota, such as hemiedaphic species, appear to depend predominantly on abiotic factors, most importantly soil pH and soil water content.

The structural complexity of agricultural landscapes influences the local biodiversity and associatedecosystem services. Hence, developing effective biodiversity management requires a betterunderstanding of the relative importance of local and landscape changes, especially for functionallyimportant organisms such as hoverflies benefiting from flowering plants.2. We examined hoverfly (Diptera: Syrphidae) communities in broad and narrow sown flowerstrips, in naturally developed grassy strips and in wheat fields (as a control). We also investigatedthe effects of these four habitat types on syrphid occurrence in the adjacent wheat fields.3. The relative influence of local vs. landscape effects was tested by selecting study sites along agradient of structural complexity from simple landscapes (100% arable land) to complex landscapes(up to 70% semi-natural habitats such as fallows, field margins, hedges and grassland).Landscape complexity was assessed within landscape sectors of 0Æ5–4Æ0 km radius around strips.4. Syrphid density and in particular, the density of aphidophagous species, was higher in narrow andbroad sown flower strips compared to grassy strips and wheat–wheat boundary controls at the milkripeningstage of the wheat. In addition, species richness of aphidophagous syrphids within wheatfields adjacent to broad sown flower strips was higher at the wheat peak-ripening stage. This indicatesa spillover between habitats and a positive effect of these sown flower strips on potential biocontrol ofcereal aphids. Flower densities and syrphid diversity and density, respectively, were closely related.5. Species richness and abundance in the sown flower strips increased as the proportion of arableland in the surrounding landscape increased, suggesting that within structurally simple landscapes(at 0Æ5–1 km radius around the sites) syrphid flies concentrated on the most rewarding resourceswithin the sown flower strips. Sown flower strips were more effective at increasing syrphid speciesrichness and abundance in simple landscapes, presumably because the creation of flower resourcesmade the greatest difference in such homogeneous, intensively managed arable landscapes.6.

Applying the same sampling techniques, we revisited 26 of the original sites in 2008 and 2009. Nearly all sites are controlled by conservation policies and changes in vegetation composition were relatively small, although some sites showed shrub encroachment. Changes in orthopteran diversity were not significant. Community composition showed minor changes which were correlated with evidence of woody plant encroachment as derived from historical and recent aerial imagery. The frequency of some Caelifera species decreased from the 1960s to 2008/2009 with one species inhabiting bare soils (Myrmeleotettix maculatus) showing the strongest decline. Some Ensifera, especially two species inhabiting open woodland and scrub (Tettigonia viridissima, Phaneroptera falcata) showed positive trends. Nevertheless, three different regions (each belonging to a different German federal state) had shown distinct orthopteran assemblages in the 1960s, and these were equally different 40 years later. We conclude that the orthopteran fauna of Central European protected dry grasslands showed small changes in species composition, and overall diversity remained rather constant during the past 40 years, which is in accordance with the minor changes in the surrounding landscape.

However, differences in assemblage structure and diversity can have consequences for their functional impact. Such differences are particularly evident across latitudes, and their analysis can help to generate a better understanding of region-specific characteristics of predator assemblages. Here, we analyse the relationships between species richness, family richness and functional diversity (FD) as well as alpha- and beta-components of epigeic spider diversity in semi-natural temperate and subtropical forest sites. As expected, within-plot and overall spider species and family richness were higher in the subtropical plots. In contrast, local FD within plots was similar between sites, and differences in FD only became evident at larger spatial scales due to higher species turnover in the subtropical forests. Our study indicates that the functional effects of predator assemblages can change across spatial scales. We discuss how differences in richness and functional diversity between contrasting forest ecosystems can depend on environmental heterogeneity and the effects of species filters acting at local scales. The high turnover observed in the species-rich subtropical forests also requires a more regional perspective for the conservation of the overall diversity and the ecological functions of predators than in less diverse forests, as strategies need to account for the large spatial heterogeneity among plots.
