The project aims at achieving a better understanding of the processes that drive or limit the response of grassland systems in a world of increasing atmospheric pCO2. We will test the hypothesis that the previously shown increase in below-ground allocation of C under elevated pCO2 provides the necessary energy excess and will stimulate free-living N2 fixers in a low N grassland environment. The project thus aims at assessing the occurrence and importance of free-living N2 fixers under elevated pCO2 and identify the associated microbial communities involved in order to better understand ecosystems response and sustainability of grassland systems. This project had the last opportunity to obtain soil samples from a grassland ecosystem adapted to long-term (10 year) elevated atmospheric pCO2 as the Swiss FACE experiment. The project aims to identify the relevant components of free-living diazotrophs of the microbial community using 15N stable isotope - DNA probing.
In order to study the effects of parasitoid associated factors on lepidopteran larval hosts we used g-irradiation of sterilize females of the braconid parasitoid Glyptapanteles liparidis. Along with eggs, G. liparidis females inject a secrete of the calyx gland containing particles of a symbiotic virus, the polydnavirus (PDV) and venom into the host. These associated factors are known from other host-parasitoid systems to suppress the immune system of the host and cause alterations in its development. g-irradiation should sterilize the eggs inside the wasp's ovary, so that sterile eggs are oviposited together with PDV and venom and the influence of parasitoid larvae inside the host is excluded. We irradiated G. liparidis females with different doses, ranging from 2.4 to 10.5 krad, in a Co60 g-irradiator. L. dispar larvae were stung by such irradiated wasps as well as untreated wasps, and the development of hosts and parasitoid progeny was controlled by rearing and dissections of hosts. Also G. liparidis were reared under controlled conditions to measure the effect of irradiation on their longevity and oviposition. A sting by an irradiated wasp (= pseudoparasitization) caused prolonged development and supernumerary molts of L. dispar larvae, and lead to the production of heavier pupae. However, such pseudoparasitized hosts suffered from higher pupal mortality due to incomplete larval-pupal molts or incomplete hardening of pupal cuticle. Effects on the host immune system were studied indirectly using an additional infection with the entomopathogenic microsporidium Vairimorpha sp. Pseudoparasitized hosts died earlier from the microsporidiosis and showed infections of higher intensity. For G. liparidis adults the g-irradiation caused no marked reduction in lifespan, except at the highest dose of 10.5 krad, but irradiated females laid significantly fewer eggs. The treatment did not result in complete sterilisation; about 10 to 20 percent of parasitoid eggs did hatch and such G. liparidis were able to complete their development to adults. Further studies will investigate the incomplete sterilization of G. liparidis eggs by g-irradiation. We will test whether these synovigenic wasps can recover after a certain time after irradiation and produce fertile eggs again. Consequently, we aim to develop a protocol of dose and timing of g-irradiation to give the best results for using it as a tool in studying the effects of PDV and venom of G. liparidis.
Recent events such as the Pakistan earthquake, Hurricane Katrina, the Indian Ocean tsunami and the European heat waves of 2003 reveal the vulnerability of societies to extreme events. The goal of this project is to strengthen prevention, mitigation and preparedness strategies in order to reduce the health, social and economic impacts of extreme events on communities. The objectives of the MICRODIS project are to strengthen the scientific and empirical foundation on the relationship between extreme events and their impacts; to develop and integrate knowledge, concepts, methods and databases towards a common global approach and to improve human resources and coping capacity in Asia and Europe through training and knowledge sharing. This integrated project involves 19 partners from Asia and Europe, including research, policy and ground roots institutions. The outputs will include an evidence-base on impacts, field methodologies and tools for data compilation, impact models, and integrated vulnerability assessments. It will also strengthen standardised data collection of extreme events and their impacts at local, regional and global levels.

Earthquake and landslide risk is a public safety issue that requires appropriate mitigation measures and means to protect citizens, property, infrastructure and the built cultural heritage. Mitigating this risk requires integrated and coordinated action that embraces a wide range of organisations and disciplines. For this reason, the LESSLOSS IP is formulated by a large number of European Centres of excellence in earthquake and geotechnical engineering integrating in the traditional fields of engineers and earth scientists some expertise of social scientists, economists, urban planners and information technologists. The LESSLOSS project addresses natural disasters, risk and impact assessment, natural hazard monitoring, mapping and management strategies, improved disaster preparedness and mitigation, development of advanced methods for risk assessment, methods of appraising environmental quality and relevant pre-normative research. In order for the multi-disciplinary S&T ingredients of the project to be tackled in an efficient and productive manner, the research programme has been split into three distinct areas: physical environment, urban areas and infrastructures. For each one of this areas four main types of transversal fields have been identified as fundamental and capable of producing permanent effects on risk mitigation: (i) instrumentation and monitoring, (ii) methods and technologies to reduce vulnerability, (iii) innovative approaches for design/assessment and (iv) disaster scenarios and loss modelling. Within this general framework, specific objectives will be pursued, such as the development of innovative methods and approaches to design and assessment of structures and earth slopes for both short- and long-term implementation, the development of advanced monitoring techniques and devices, and the development, manufacturing and testing of innovative isolating and dissipating seismic devices.

Der aktuelle Sachstand bei der Erstellung von Luftreinhalte- und Aktionsplänen in Deutschland wird mit Hilfe einer eingehenden Analyse derzeit veröffentlichter Pläne beschrieben (Stand: 31.08.2008). Diese Pläne stellen in der Zusammenschau eine umfangreiche Darstellung der aktuellen Luftschadstoffsituation, der verschiedenen Methoden der Prognose und der diskutierten Maßnahmen dar. Als wichtiges Hilfsmittel der vergleichenden Auswertung dient die Darstellung der Daten der Luftreinhaltepläne als thematische Karte. Es gibt zahlreiche strukturelle und inhaltliche Unterschiede zwischen den verschiedenen Entwicklungsstufen der Pläne und ebenso zwischen den Plänen verschiedener Bundesländer. Zur Klassifizierung der in den Plänen genannten Maßnahmen wurde in den vorigen Arbeiten (FKZ 204 42 222) und (FKZ 363 01 140) ein Maßnahmenschema entwickelt, das im vorliegenden Bericht nochmals erweitert wurde. Mit diesem Analysewerkzeug wurden alle bis zum 31.08.2008 vorgelegten Veröffentlichungen, d. h. Pläne, Fortschreibungen und Entwürfe, systematisch erfasst und untersucht. Um die Vergleichbarkeit der in den Plänen aufgeführten Maßnahmen zu gewährleisten, wurde die in den Vorgängerarbeiten entwickelte Zusammenstellung von standardisierten Maßnahmen weitergeführt. Diese sogenannten Standard- Maßnahmen stellen ein zentrales Element der Maßnahmenanalyse dar und bilden alle Maßnahmen ab, die in Deutschland laut den vorgelegten Plänen durchgeführt, geplant oder diskutiert werden. Die erneute Aktualisierung dient insbesondere auch dazu festzustellen, mit welchen Maßnahmen die Länder planen, die ab 2010 gültigen Luftqualitätsgrenzwerte einzuhalten. Umweltzonen haben sich, wie bereits in den Vorgängerarbeiten gezeigt, als wichtiges Element im Maßnahmenbündel etabliert. Die neue Bestandsaufnahme erfasst auch den aktuellen und geplanten Stand der Umweltzonen. Das Vorhaben diskutiert darüber hinaus die Abschätzung der Wirksamkeit der Maßnahmen im Hinblick auf das Minderungspotenzial für PM10-Feinstaub und Stickstoffdioxid unter Berücksichtigung anderer nationaler Wirkungsuntersuchungen.
Background: It has been hypothesized, that children could be more vulnerable to radio frequency electromagnetic field exposures from mobile telephones than adults, but no epidemiological studies of the relationship have been performed so far. The lack of knowledge causes conflicting recommendations from decision-makers, leading to anxiety and insecurity in the population. WHO has put a case-control study on childhood brain tumours as high priority on their 2006 research agenda on radio frequency electromagnetic fields. Objectives: The main goal of the study is to investigate whether use of mobile telephones increases the risk of developing brain tumours for children or adolescents. In addition, our study will provide a comprehensive dataset to investigate other potential risk factors for childhood brain tumour. Study design: The questions under study will be investigated by means of a case-control study in Denmark, Norway, Sweden and Switzerland. Cases will be identified through a combination of registry data and information from the wards treating the patients (e.g. Swiss Paediatric Oncology Group: SPOG). All incident cases of brain tumour in the age group 7-19 years between May 2004 and April 2008 will be invited to participate. In total, the study is expected to include 550 cases of brain tumours in the participating countries, thereof 100 originating from Switzerland. For each case, two control persons will be randomly selected from the general population, matched on age, sex and geographic regions. Exposure assessment: Information on the extent of exposure to radio frequency fields from mobile phones and on other known and suspected risk factors for childhood brain tumours will be obtained by means of computer assisted personal interviews conducted by an interviewer trained for this purpose. The interviews will take place either at the hospital or at the study participant's home. Objective information on the frequency and duration of mobile phone use will be obtained from mobile phone operators and from the information stored in the telephone that is in current use. Data analyses: The data will be analyzed using established statistical methods for case-control studies, primarily via logistic regression models adjusted for potential confounding factors. In order to investigate potential gene-environment interactions, DNA from saliva samples will be extracted and analysed. Polymorphisms in genes that affect oxidative metabolism, detoxification of carcinogens, DNA stability and repair, or immune response, are candidates that might confer genetic susceptibility to brain tumors.
Communications, data and information exchange are the key elements of the operational ocean monitoring and forecasting networks, defined in the Global Ocean Observing System (GOOS). Development of observing and closely related operational forecasting system in the Black Sea region requires the exchange of significant data and information volumes. ASCABOS is designed to strengthen the communication system ensuring flexible and operative infrastructure for data and information exchange between partners and end users. ASCABOS aims to increase public awareness and to stimulate and motivate the utilization of operational oceanographic information in management and decision-making practices. In the same time, high level of the operational services must be built and retained. ASCABOS will support achievement of these crucial objectives by initiating an educational and training programme designed for young scientists and wide spectrum of end users. Considerable work has been performed on compiling meta-databases on the Black Sea environmental data, information and research within previous international initiatives and projects. To support and to strengthen the exchange between scientists, governmental managers and other users ASCABOS is planning to combine experiences and instruments in order to develop a Black Sea information system, containing all available metadata, validated and efficiently updated through the Internet. ASCABOS plans to organize and realize a cost-effective VOS pilot programme, applying modern technologies and developments for data collection, transmission, storage, use and dissemination. The VOS programme will provide data for model assimilation and respond to the GOOS demand for long-term monitoring of the marine ecosystems.

Differenzierung der Quellen- und Senkenfunktion des Bodens unter Berücksichtigung der Nutzungsgeschichte. Im Rahmen des CARBOEUROFLUX-Projekts wurden im Hainich (Thüringen) Kohlenstoff (C)- Speicherungsraten festgestellt, die der Vorstellung der Kohlendioxid-Neutralität von alten Wäldern widersprechen und die Frage nach deren Kyoto-Relevanz aufwerfen. Im Rahmen europäischer Projekte lässt sich allerdings nicht klären, wie diese hohen Speicherraten entstehen und wo C im System verbleibt. Wir vermuten, dass durch historischen C-Export, z.B. infolge von Streunutzung, die Böden im Hainich verarmten und die entleerten Speicher jetzt wieder aufgefüllt werden. Um das Ausmaß des nutzungsbedingten C-Exports abschätzen zu können, werden aus Schriftquellen Art und Umfang der Biomassenutzung in ihrer zeitlichen und örtlichen Entwicklung rekonstruiert. Zudem untersuchen wir, welche Anteile des C-Eintrages veratmet, gespeichert und über den Wasserpfad exportiert werden. Hierzu werden 13C und 14C- Isotopenverhältnisse an Bodengasen sowie gelöstem und festem Boden- C bestimmt. Unsere Untersuchungen zielen auf ein grundlegendes Verständnis der C-Speicherung im Jahresverlauf ab. Die Zusammenarbeit mit dem Kompetenzzentrum 'Dynamik Komplexer Geosysteme' und dem europäischen CARBOEUROPE Cluster wird die Doppelerhebung von Daten verhindern und deren gegenseitige Verfügbarkeit sicherstellen. Ziel der Arbeit ist es, den historischen Kohlenstoffexport insbesondere unter Berücksichtigung der forstlichen Nebennutzung abzuschätzen. Hierzu soll anhand von Literaturdaten einerseits die Vegetationsgeschichte geklärt werden. Andererseits soll der im Untersuchungsgebiet im Zuge der forstlichen und landwirtschaftlichen Nutzungen erfolgte Biomasseentzug nach Art und Umfang dokumentiert werden. Diese Arbeiten sind notwendig, um den Einfluss der Nutzungsgeschichte auf die Kohlenstoffspeicherung im Untersuchungsstandort abzuschätzen. Im Rahmen des Gesamtprojektes sollen zunächst Daten zur Entwicklung der Biomasse im Untersuchungsgebiet zusammengestellt werden. Eine weitere Aufgabe besteht darin, auf der Basis von Literaturstudien einen möglichen Vergleichsstandort mit unterschiedlicher Nutzungsgeschichte zu identifizieren.
In contrast to their advances in other areas, weather forecast models have not been successful in improving the Quantitative Precipitation Forecast during the last 16 years. One reason for this stagnation is the lack of comprehensive, high-quality data sets usable for model validation as well as for data assimilation, thus leading to improved initial fields in numerical models. Theoretical analyses have identified the requirements measured data have to meet in order to close the gaps in process understanding. In field campaigns, it has been shown that the newest generation of remote sensing systems has the potential to yield data sets of the required quality. It is therefore time to combine the most powerful remote sensing instruments with proven ground-based and airborne measurement techniques in an Intensive Observations Period (IOP). Its goal is to serve as a backbone for the SPP 1167 by producing the demanded data sets of unachieved accuracy and resolution. This requires a sophisticated scientific preparation and a careful coordination between the efforts of the institutions involved. For the first time, the pre-convective environment, the formation of clouds and the onset and development of precipitation as well as its intensity will be observed in four dimensions simultaneously in a region of sufficient size. This shall be achieved by combining the IOP with international programs and by collaboration between leading scientists in Europe, US and other countries. Thus, the IOP is a unique opportunity to make Germany the setting of an international field campaign featuring the newest generation of measurement systems such as scanning radar and lidar and leading to outstanding advances in atmospheric sciences.
Context: With increasing global change pressures, and due to existing limitations, and un-sustainability factors and risks of conventional urban water management (UWM), cities experience difficulties in efficiently managing the ever scarcer water resources, their uses/services, and their after-use disposal, without creating environmental, social and/or economic damage. In order to meet these challenges, SWITCH calls for a paradigm shift in UWM. There is a need to convert adhoc actions (problem/incident driven) into a coherent and consolidated approach (sustainability driven). This calls for an IP Approach. Research conceptSWITCH therefore proposes an action research project which has as a main objective: The development, application and demonstration of a range of tested scientific, technological and socio-economic solutions and approaches that contribute to the achievement of sustainable and effective UWM schemes in 'The City of the future'.The project will be implemented by different combinations of consortium partners, along the lines of seven complementary and interactive themes. The research approach is innovative for the combination of: action research: address problems through innovation based upon involvement of users.learning alliances: to link up stakeholders to interact productively and to create win-win solutions along the water chain; multiple-way learning: European cities learn from each other and from developing countries, and vice versa.multiple-level or integrated approach: to consider the urban water system and its components (city level) in relation to its impacts on, and dependency of, the natural environment in the river basin (river basin level), and in relation to Global Change pressures (global level).Instruments and scopeAn IP with 30 partners, their resources, and a total budget of 25,191,396 EURO including budget for demonstration activities in 9 Cities in Europe and developing countries.
