They are expected to enhance the resistance of wood to weathering because they can cross-link the cell wall and dimensionally stabilise wood. Scots pine veneers were modified with 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU) to weight percent gains (WPG) of 10 %, 27 % or 48 % and exposed to artificial weathering. Initially, weight losses of unmodified veneers were significantly greater than those of DMDHEU treated specimens even though DMDHEU was leached from wood at a higher rate than loss of wood substance. The weight losses of all treated veneers after 144 h of weathering, however, were similar to those of the unmodified controls. Therefore we conclude that in the short term DMDHEU treatment can restrict weight losses of wood during weathering, which occur due to degradation of lignin and hemicellulose and loss of degraded wood fragments from wood. Infrared spectroscopy suggested that treatment of wood veneers with DMDHEU to high WPG (48 %) stabilised lignin to some extent. Tensile strength losses of DMDHEU treated veneers during weathering were lower than those of untreated veneers. DMDHEU treatment, however, had a deleterious effect on the tensile strength of the veneers, possibly associated with the presence of magnesium chloride catalyst in the treatment solution. Scanning electron microscopy revealed that DMDHEU treatment was highly effective at preventing the degradation of the wood cell wall during weathering. Tracheids in unmodified veneers became distorted within 48 It of weathering exposure, whereas cells in modified veneers, especially those reacted to higher weight percent gains, retained their shape even after 144 h weathering.

Here, we investigated the minimum number of independent colonisations of marine and freshwater habitats in derived oribatid mites (Brachypylina), a mainly terrestrial taxon. Furthermore, we investigated whether the reproductive mode (sexual vs. thelytokous) is associated with the habitat type (marine, freshwater) where the animals live. We hypothesized that continuous resource availability in freshwater systems fosters asexual reproduction. We used 18S rDNA sequences to construct a molecular phylogeny of oribatid mites from terrestrial, marine and freshwater habitats. The results indicate that aquatic life in oribatid mites evolved at least 3x: once in Limnozetoidea (including only freshwater taxa) and at least twice in Ameronothroidea. In Ameronothroidea the taxon Ameronothridae n. gen. (nr. Aquanothrus) colonized fresh water independently from Selenoribatidae and Fortuyniidae (mainly marine Ameronothroidea). Reproductive mode was associated neither with marine nor with freshwater life; rather, in both habitats sexual and parthenogenetic taxa occur. However, the reproductive mode was related to the stability of the habitat. Species that live underwater permanently tend to be parthenogenetic whereas taxa whose life cycle is often interrupted by flooding, such as marine oribatid mites, or by desiccation, e.g., freshwater-living Ameronothridae n. gen. (nr. Aquanothrus) (Ameronothroidea) species, are mainly sexual, indicating that continuous access to resources indeed favours parthenogenetic reproduction.

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"]]
