Uncertainties exist in the prediction of future land-use change impacts on these fluxes by land surface models due to scarcity of suitable measured data for parametrization and poor representation of key biogeochemical processes associated with tropical vegetation types. Rubber plantations (Havea brasilliensis) are a crucial land-use type across tropical landscapes that has greatly expanded in recent decades. Here, we first synthesize the relevant data for describing the biogeochemical processes of rubber from our past measurement campaigns in Jambi province, Indonesia. We then use these data-sets to develop a rubber plant functional type (PFT) for the Community Land Model (CLM4.5). Field measured data from small-holder plantations on leaf litterfall, soil respiration, latex harvest, leaf area index, transpiration, net primary productivity, and above-ground and fine root biomass were used to develop and calibrate a new PFT-based model (CLM4.5-rubber). CLM-rubber predictions adequately captured the annual net primary productivity and above-ground biomass as well as the seasonal dynamics of leaf litterfall, soil respiration, soil moisture and leaf area index. All of the predicted water fluxes of CLM-rubber were very similar to a site-specific calibrated soil water model. Including temporal variations in leaf life span enabled CLM-rubber to better capture the seasonality of leaf litterfall. Increased sensitivity of stomata to soil water stress and the enhancement of growth and maintenance respiration of fine roots in response to soil nutrient limitation enabled CLM-rubber to capture the magnitude of transpiration and leaf area index. Since CLM-rubber predicted reasonably well the carbon and water use, we think that the current model can be used for larger-scale simulations within Jambi province because more than 99% of the rubber plantations are smallholder owned in Jambi province and have low soil fertility."],["dc.identifier.doi","10.5194/gmd-2018-236"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62628"],["dc.language.iso","en"],["dc.relation.issn","1991-962X"],["dc.relation.orgunit","Abteilung Bioklimatologie"],["dc.title","Observation-based implementation of ecophysiological processes for a rubber plant functional type in the community land model (CLM4.5-rubber_v1)"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. Therefore, this thesis aims to draw a conclusive picture of the surface energy exchange and land-atmosphere interactions of Arctic and subarctic regions under climate change. The aims are achieved by combining in-situ field measurements of surface energy balance components, snow manipulation experiments, active layer monitoring, vegetation mapping, and chamber-based carbon dioxide flux measurements from Arctic and subarctic tundra biomes in Greenland, Svalbard and northern Sweden. Local variability in climate, surface structure, soil moisture and soil thermal regime are the main drivers of variation in the surface energy exchange and ecosystem productivity of Arctic and subarctic tundra ecosystems. At all studied locations, the magnitude of the energy fluxes of sensible heat (H), latent heat (LE) and ground heat (G) were well-correlated with net radiation (Rnet). However, evapotranspiration (ET) and LE showed a relatively strong coupling to atmospheric vapor pressure deficit (VPD), with more pronounced such control at the dry tundra sites compared to the wet-growing ecosystems. Snow and permafrost determined surface energy balance, energy partitioning and ecosystem productivity. Manipulated increase in snow accumulation at a subarctic tundra peatland complex in northern Sweden resulted in permafrost thaw, soil wetting and increased carbon sequestration. Concurrently, climate-driven increase in both snow accumulation and air temperature triggered dramatic and rapid permafrost degradation in peatland complexes and transition from dry habitats into wet-growing ecosystems, with consequent change in surface energy exchange towards both increased LE and ET at the cost of H. Interannual variability in winter snow accumulation at the high-Arctic tundra environment in Zackenberg (Northeast Greenland) prolonged the growing season during a year with low snow cover and increased the total accumulated energy balance components of the local heath and fen ecosystems. Further, energy flux partitioning at the heath was strongly determined by the reduction of soil moisture as snow is by far the main supplier of water in this region. The energy exchange of the fen, however, showed attenuated behavior due to groundwater table remaining close to the surface. The results presented in this thesis suggest that in a future climate, accelerated permafrost thaw and increased interannual variability in snow cover may further modify the energy balance of Arctic and subarctic ecosystems, with profound impact on ecosystem adaptation capacities and the overall climate system."],["dc.identifier.isbn","978-91-85793-54-9"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/79688"],["dc.publisher","Lund University"],["dc.publisher.place","Lund"],["dc.subject.gro","surface energy exchange"],["dc.subject.gro","arctic and subarctic tundra"],["dc.subject.gro","climate change"],["dc.subject.gro","permafrost"],["dc.subject.gro","snow cover"],["dc.subject.gro","micrometeorology"],["dc.subject.gro","eddy covariance"],["dc.title","Surface energy exchange and land-atmosphere interactions of Arctic and subarctic tundra ecosystems under climate change"],["dc.type","thesis"],["dc.type.internalPublication","no"],["dc.type.subtype","dissertation"],["dspace.entity.type","Publication"]]

Changes in the carbon cycle associated with land-use change can be estimated through Land Surface Models (LSMs). The accuracy of carbon flux estimation in carbon fluxes associated with land-use change has been attributed to uncertainties in the model parameters affecting photosynthetic activity, which is a function of both carboxylation capacity (Vcmax) and electron transport capacity (Jmax). In order to reduce such uncertainties for common tropical woody crops and trees, in this study we measured Vcmax25 (Vcmax standardized to 25 °C), Jmax25 (Jmax standardized to 25 °C) and light-saturated photosynthetic capacity (Amax) of Elaeis guineensis Jacq. (oil palm), Hevea brasiliensis (rubber tree), and two native tree species, Eusideroxylon zwageri and Alstonia scholaris, in a converted landscape in Jambi province (Sumatra, Indonesia) at smallholder plantations. We considered three plantations; a monoculture rubber, a monoculture oil palm, and an agroforestry system (jungle rubber plantation), where rubber trees coexist with some native trees. We performed measurements on leaves at the lower part of the canopy, and used a scaling method based on exponential function to scale up photosynthetic capacity related traits to the top of the canopy. At the lower part of the canopy, we found (i) high Vcmax25 values for H. brasiliensis from monoculture rubber plantation and jungle rubber plantation that was linked to a high area-based leaf nitrogen content, and (ii) low value of Amax for E. guineensis from oil palm plantation that was due to a low value of Vcmax25 and a high value of dark respiration. At the top of the canopy, Amax varied much more than Vcmax25 among different land-use types. We found that photosynthetic capacity declined fastest from the top to the lower part of the canopy in oil palm plantations. We demonstrate that photosynthetic capacity related traits measured at the lower part of the canopy can be successfully scaled up to the top of the canopy. We thus provide helpful new data that can be used to constrain LSMs that simulate land-use change related to rubber and oil palm expansion."],["dc.identifier.doi","10.3390/f12030359"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/80655"],["dc.identifier.url","https://publications.goettingen-research-online.de/handle/2/80655"],["dc.language.iso","en"],["dc.notes.intern","DeepGreen Import"],["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","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.doi","10.3390/f12030359"],["dc.relation.eissn","1999-4907"],["dc.relation.issn","1999-4907"],["dc.relation.orgunit","Zentrum für Biodiversität und Nachhaltige Landnutzung"],["dc.relation.orgunit","Abteilung Bioklimatologie"],["dc.rights","https://creativecommons.org/licenses/by/4.0/"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Using a Bottom-Up Approach to Scale Leaf Photosynthetic Traits of Oil Palm, Rubber, and Two Coexisting Tropical Woody Species"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

The El Niño–Southern Oscillation (ENSO) in 2015 was one of the strongest observed in almost 20 years and set the stage for a severe drought and the emergence of widespread fires and related smoke emission over large parts of Southeast Asia. In the tropical lowlands of Sumatra, which were heavily affected by the drought and haze, large areas of tropical rainforest have been converted into oil palm (Elaeis guineensis Jacq.) plantations during the past decades. In this study, we investigate the impact of drought and smoke haze on the net ecosystem CO2 exchange, evapotranspiration, yield and surface energy budget in a commercial oil palm plantation in Jambi province (Sumatra, Indonesia) by using micrometeorological measurements, the eddy covariance method, yield data and a multiple linear regression model (MLRM). With the MLRM we identify the contribution of meteorological and environmental parameters to the net ecosystem CO2 exchange. During the initial part of the drought, when incoming shortwave radiation was elevated, net CO2 uptake increased by 50 % despite a decrease in upper-layer soil moisture by 35 %, an increase in air temperature by 10 % and a tripling of atmospheric vapour pressure deficit. Emerging smoke haze decreased incoming solar radiation by 35 % compared to non-drought conditions and diffuse radiation almost became the sole shortwave radiation flux for 2 months, resulting in a strong decrease in net CO2 uptake by 86 %. Haze conditions resulted in a complete pause of oil palm net carbon accumulation for about 1.5 months and contributed to a decline in oil palm yield by 35 %. With respect to a projected pronounced drying trend over the western Pacific during a future El Niño, our model showed that an increase in drought may stimulate net CO2 uptake, while more severe smoke haze, in combination with drought, can lead to pronounced losses in productivity and net CO2 uptake, highlighting the importance of fire prevention. </jats:p>"],["dc.identifier.doi","10.5194/bg-16-2873-2019"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16752"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/104573"],["dc.language.iso","en"],["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.issn","1726-4189"],["dc.relation.orgunit","Department für Nutzpflanzenwissenschaften"],["dc.relation.orgunit","Fakultät für Agrarwissenschaften"],["dc.relation.orgunit","Abteilung Pflanzenbau"],["dc.relation.orgunit","Abteilung Bioklimatologie"],["dc.rights","CC BY 4.0"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","El Niño–Southern Oscillation (ENSO) event reduces CO2 uptake of an Indonesian oil palm plantation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
