When consumers have a strong preference for species rarity, trade could result in wildlife overexploitation and species extinction. Results from a choice experiment show that buyers of caged birds indeed value species rarity. However, not all rare species are equally preferred. Species that are frequently traded lose their rarity value, even if rare in the wild. Analysis of time-series data collected from traders over a period of 20 months between 2013 and 2015 reveals an inelastic supply function for rare species, with market arrivals being insensitive to price changes. This may be due to a declining stock of rare species in the wild. Bird trade together with habitat loss can lead to extinction of a number of rare species in Indonesia.

Conservation measures are needed to assess and reduce the impact of agricultural intensification on the vertebrate fauna, but limited effort has been put so far in understanding the effects of habitat conversion on reptiles and amphibians. Here we study community composition, species richness and abundance of the herpetofauna of the densely farmed Jambi province, central Sumatra (Indonesia). We compared reptile and amphibian communities of upland and riparian sites of lowland rainforest as well as upland and riparian sites of oil palm and rubber plantations through visual-aural encounter surveys and pitfall trappings. Plantations tended to have lower amphibian abundance when compared to riparian forest, but not compared to upland forest. There is a trend for higher amphibian numbers and species in riparian sites of all habitat types. Rare amphibians were much more abundant in riparian forest and common amphibians were more prevalent in plantations, especially oil palm. Surprisingly, reptile richness and abundance was higher in oil palm plantations than all other habitats. Plantations comprise mostly common reptile and amphibian species of low conservation interest, and communities were markedly different between plantations and forests. Several species were recorded for the first time in the sampled region. We conclude that in our region, riparian sites appear to be important for maintaining amphibian populations, but forest is doubtlessly irreplaceable to conserve rare amphibians.

The ecological drivers of oil palm pollination are still poorly understood, despite pollination being a key ecosystem service for the yield of this multi-billion-dollar industry, with potential links to biodiversity conservation. Here we review biotic and abiotic drivers of pollination and known oil palm pollinators, including local insect species endemic to specific growing regions, and an important, globally-introduced West African weevil (Elaeidobius kamerunicus) whose fluctuating populations have led to concerns about yield and resilience. Future research should clarify pollinator community dynamics to facilitate pollination complementarity, which may strengthen pollination services in regions beyond the oil palm and weevil’s native West African ecosystem. In addition, other interactions such as mutualism, predation, and parasitism are not yet well understood, but could provide further insight into population drivers. Future management research should explore manipulating male palm inflorescence density, a key resource for pollinators, as well as investigate spatial and landscape effects on pollinator populations. Critically, no studies have investigated the effects of climate change on pollination, despite the impacts of rain and temperature on pollination efficiency. A greater understanding of the role of pollinator species and their nonlinear relationships to yield, as well as the complexity of biotic, management, and climate drivers of successful pollination can contribute to a more sustainable oil palm production system that values ecosystem services gained from biodiversity, while also improving producer livelihoods."],["dc.identifier.doi","10.1016/j.agee.2019.05.001"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61858"],["dc.language.iso","en"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B09: Oberirdische Biodiversitätsmuster und Prozesse in Regenwaldtransformations-Landschaften"],["dc.relation.issn","0167-8809"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Critical factors limiting pollination success in oil palm: A systematic review"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Oil palm monocultures have been criticized because of their reduced biodiversity compared to the forests they historically replaced, and because of their negative impact on soils, water, and climate. We experimentally test whether less intensive management schemes may enhance biodiversity and lessen detrimental effects on the environment while maintaining high yields. We compare reduced vs. conventional fertilization, as well as mechanical vs. chemical weed control (with herbicides) in a long-term, full-factorial, multidisciplinary experiment. We conducted the experiment in an oil palm company estate in Sumatra, Indonesia, and report the results of the first 2 years. We measured soil nutrients and functions, surveyed above- and below-ground organisms, tracked oil palm condition and productivity, and calculated plantation gross margins. Plants, aboveground arthropods, and belowground animals were positively affected by mechanical vs. chemical weed control, but we could not detect effects on birds and bats. There were no detectable negative effects of reduced fertilization or mechanical weeding on oil palm yields, fine roots, or leaf area index. Also, we could not detect detrimental effects of the reduced fertilization and mechanical weeding on soil nutrients and functions (mineral nitrogen, bulk density, and litter decomposition), but water infiltration and base saturation tended to be higher under mechanical weeding, while soil moisture, and microbial biomass varied with treatment. Economic performance, measured as gross margins, was higher under reduced fertilization. There might be a delayed response of oil palm to the different management schemes applied, so results of future years may confirm whether this is a sustainable management strategy. Nevertheless, the initial effects of the experiment are encouraging to consider less intensive management practices as economically and ecologically viable options for oil palm plantations."],["dc.identifier.doi","10.3389/ffgc.2019.00065"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62760"],["dc.language.iso","en"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | A | A02: Wassernutzungseigenschaften von Bäumen und Palmen in Regenwald-Transformationssystemen Zusammenfassung"],["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 | A | A07: Räumlich-zeitliche Skalierung des Einflusses von Landnutzung und Klimawandel auf Landnutzungssysteme in Indonesien"],["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 | B07: Functional diversity of mycorrhizal fungi along a tropical land-use gradient"],["dc.relation","SFB 990 | B | B08: Struktur und Funktion des Zersetzersystems in Transformationssystemen von Tiefland-Regenwäldern"],["dc.relation","SFB 990 | B | B09: Oberirdische Biodiversitätsmuster und Prozesse in Regenwaldtransformations-Landschaften"],["dc.relation","SFB 990 | B | B13: Impact of management intensity and tree enrichment of oil palm plantations on below- and aboveground invertebrates in Sumatra (Indonesia)"],["dc.relation","SFB 990 | C | C07: Einflussfaktoren von Landnutzungswandel und sozioökonomische Auswirkungen für ländliche Haushalte"],["dc.relation.eissn","2624-893X"],["dc.relation.issn","2624-893X"],["dc.relation.orgunit","Zentrum für Biodiversität und Nachhaltige Landnutzung"],["dc.relation.orgunit","Abteilung Bioklimatologie"],["dc.rights","CC BY 4.0"],["dc.rights.uri","http://creativecommons.org/licenses/by/4.0/"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Reducing Fertilizer and Avoiding Herbicides in Oil Palm Plantations - Ecological and Economic Valuations"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

For birds in particular, survey methods have been tested extensively using point counts and sound recording surveys. Here, we review the latest evidence for this taxon within the frame of a systematic map. We compare sampling effectiveness of these two survey methods, the output variables they produce, and their practicality. When assessed against the standard of point counts, autonomous sound recording proves to be a powerful tool that samples at least as many species. This technology can monitor birds in an exhaustive, standardized, and verifiable way. Moreover, sound recorders give access to entire soundscapes from which new data types can be derived (vocal activity, acoustic indices). Variables such as abundance, density, occupancy, or species richness can be obtained to yield data sets that are comparable to and compatible with point counts. Finally, autonomous sound recorders allow investigations at high temporal and spatial resolution and coverage, which are more cost effective and cannot be achieved by human observations alone, even though small-scale studies might be more cost effective when carried out with point counts. Sound recorders can be deployed in many places, they are more scalable and reliable, making them the better choice for bird surveys in an increasingly data-driven time. We provide an overview of currently available recorders and discuss their specifications to guide future study designs."],["dc.identifier.doi","10.1002/eap.1954"],["dc.identifier.pmid","31206926"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61854"],["dc.language.iso","en"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B09: Oberirdische Biodiversitätsmuster und Prozesse in Regenwaldtransformations-Landschaften"],["dc.relation.issn","1051-0761"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Autonomous sound recording outperforms human observation for sampling birds: a systematic map and user guide"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Especially in Southeast Asia, the oil palm boom has contributed to economic growth, but it has also spurred criticism about negative environmental and social effects. Here, we discuss palm oil production and consumption trends and review environmental, economic, and social consequences in different parts of the world. The oil palm expansion has contributed to tropical deforestation and associated losses in biodiversity and ecosystem functions. Simultaneously, it has increased incomes, generated employment, and reduced poverty among farm and nonfarm households. Around 50% of the worldwide oil palm land is managed by smallholders. Sustainability trade-offs between preserving global public environmental goods and private economic benefits need to be reduced. We discuss policy implications related to productivity growth, rainforest protection, mosaic landscapes, land property rights, sustainability certification, and smallholder inclusion, among others."],["dc.identifier.doi","10.1146/annurev-resource-110119-024922"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/82283"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B09: Oberirdische Biodiversitätsmuster und Prozesse in Regenwaldtransformations-Landschaften"],["dc.relation","SFB 990 | C | C07: Einflussfaktoren von Landnutzungswandel und sozioökonomische Auswirkungen für ländliche Haushalte"],["dc.relation.eissn","1941-1359"],["dc.relation.issn","1941-1340"],["dc.relation.orgunit","Department für Agrarökonomie und Rurale Entwicklung"],["dc.rights","CC BY 4.0"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Environmental, Economic, and Social Consequences of the Oil Palm Boom"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
