Field-scale experiments simulating realistic future climate scenarios are important tools for investigating the effects of current and changes on ecosystem functioning biogeochemical cycling. We exposed a seminatural Danish heathland to elevated atmospheric carbon dioxide (CO2), warming, extended summer drought in all combinations. Here, we report short-term responses nitrogen (N) cycle after 2 years treatments. Elevated CO2 significantly affected aboveground stoichiometry by increasing...
Abstract. Empirical evidence demonstrates that lakes and reservoirs are warming across the globe. Consequently, there is an increased need to project future changes in lake thermal structure resulting biogeochemistry order plan for likely impacts. Previous studies of impacts climate change on have often relied a single model forced with limited scenario-driven projections relatively small number lakes. As result, our understanding effects fragmentary, based scattered using different data...
1 Recent findings indicate that the interactions among CO2, temperature and water can be substantial, combined effects on biological systems of several factors may not predicted from experiments with one or a few factors. Therefore realistic multifactorial involving larger set main are needed. 2 We describe new Danish climate change-related field scale experiment, CLIMAITE, in heath/grassland ecosystem. CLIMAITE is full factorial combination elevated prolonged summer drought. The...
Abstract. Advance warning of seasonal conditions has the potential to assist water management in planning and risk mitigation, with large social, economic, ecological benefits. In this study, we explore value forecasting for decision-making at five case study sites located extratropical regions. The tools used integrate climate model forecasts freshwater impact models catchment hydrology, lake (temperature, level, chemistry, ecology), fish migration timing were co-developed together...
Abstract This study investigated the impact of predicted future climatic and atmospheric conditions on soil respiration ( R S ) in a Danish Calluna‐Deschampsia‐ heathland. A fully factorial situ experiment with treatments elevated CO 2 (+130 ppm), raised temperature (+0.4 °C) extended summer drought (5–8% precipitation exclusion) was established 2005. The average , observed control over 3 years measurements (1.7 μmol m −2 sec −1 ), increased 38% under irrespective combination or treatments....
Global change factors affect plant carbon uptake in concert. In order to investigate the response directions and potential interactive effects, understand underlying mechanisms, multifactor experiments are needed. The focus of this study was on photosynthetic elevated CO2 [CO2; free air enrichment (FACE)], drought (D; water-excluding curtains), night-time warming (T; infrared-reflective curtains) a temperate heath. A/Ci curves were measured, allowing analysis light-saturated net...
The impact of elevated CO₂, periodic drought and warming on photosynthesis leaf characteristics the evergreen dwarf shrub Calluna vulgaris in a temperate heath ecosystem was investigated. Photosynthesis reduced by midsummer increased CO₂ throughout growing season, whereas only stimulated early year. At beginning end T × interaction synergistically plant carbon uptake combination CO₂. peak drought, D antagonistically down-regulated photosynthesis, suggesting limited ability to counteract...
Abstract Multiple plausible future scenarios are being used increasingly in preference to a single deterministic or probabilistic prediction of the long‐term planning water resources systems. These enable determination robustness system—the consideration performance across range futures—and allow an assessment which possible system configurations result greater level robustness. There many approaches selecting scenarios, and previous studies have observed that choice might affect estimated...
This study investigated the relative behavior of pathogens, fecal indicator organisms, and particles varying size during transport through a reservoir following storm event inflow in Myponga Reservoir, South Australia. During inflow, samples were collected from river at various locations within to determine fate microroganisms as they progressed water body. Microbiological analysis included organisms Escherichia coli, enterococci, Clostridium perfringens, aerobic spores, somatic coliphages,...
We investigated the effect of elevated [CO2], [O3] and temperature on plant productivity if these climate factors interacted with each other in multifactor treatments. The effects were studied 14 different cultivars/lines European spring oilseed rape (Brassica napus L.) barley (Hordeum vulgare L.). Seven genotypes species cultivated six single- treatments ambient or CO2 (385 ppm 700 ppm), O3 (20 ppb 60 ppb) (12/19 °C 17/24 °C). Growth production parameters measured. Elevated increased yield...
Abstract. The net ecosystem exchange of CO2 (NEE) between the atmosphere and a temperate beech forest showed significant interannual variation (IAV) decadal trend increasing carbon uptake (Pilegaard et al., 2011). objectives this study were to evaluate what extent at which temporal scale, direct climatic variability changes in functional properties regulated IAV balance site. Correlation analysis that sensitivity fluxes was significantly higher shorter than longer time scales changed...
Surface water quality has been identified as potentially vulnerable to climate change. This study assesses the impacts of change on Hsinshan Reservoir, Taiwan, through CE-QUAL-W2 simulations. The model parameters were calibrated by field data collected during 2004–2008, and verified against observations made 2009–2012. projected temperature precipitation for near- long-term future downscaled regional daily scales, used simulate changes in validated model. simulation results reported...
Abstract. Despite high potential benefits, the development of seasonal forecasting tools in water sector has been slower than other sectors. Here we assess skill for lakes and reservoirs set up at four sites Australia Europe. These consist coupled hydrological catchment lake models forced with meteorological forecast ensembles to provide probabilistic predictions anomalies discharge, temperature ice-off. Successful implementation requires a rigorous assessment tools' predictive an...
