The pollen of ragweed are known to be particularly aggressive allergens and cause a tremendous economic loss each year. Whereas Hungary has already been affected for a long time and thereby successfully established control measures both in organizational and legal terms, the plant has in Austria increasingly spread only in the last years. Since the spread takes place via Eastern neighboring countries, the province of Burgenland is particularly strongly affected. However, on the Austrian side exists at the moment neither a regulated procedure for detection and control of ragweed, nor any collaboration with Hungarian authorities. This imbalance of capacity for action of administrative systems constitutes a major challenge for the border region. As ragweed does not stop at the border, this problem can only be combated by acting together. The project has set the objective of establishing a sustainable institutional cooperation on the issue of ragweed control between the Austrian and Hungarian administrative systems and research institutions. This enables a know-how transfer that benefits both sides and improves the quality of public service and thereby also life quality of the population. In the framework of the survey and research, fundamental data will be collected (main output 1: cross-border cooperation of universities in the frame of the research activities) on the basis of which coordinated recommendations can be made in order to control and to prevent the spread. A cross-border data exchange is first made possible by establishing a common ragweed reporting system. The establishment of a bilateral ragweed task force with experts of both countries lays the foundations for a long-lasting institutional cooperation (main output 2: sustainable cross-border cooperation of administrative bodies).

The von Bertalanffy equation was developed in the 1940s and has since been the almost universal biologically motivated model to describe the ontogenetic growth of different species; it is characterized by the metabolic exponents a = 2/3, b = 1. West et al. (1997, 2001) suggested another pair of metabolic exponents (a = 2/3, b = 1) and provided biological reasoning for this choice. This project proposes biological reasoning for yet two other exponent pairs based on the ideas of Bertalanffy and West about metabolism and on a model of Parks (1982) about the dependency of growth on food intake.

BINATS 2 (BIodiversity–NATure–Safety) aims at a further survey of plant and animal diversity in the Austrian agrarian regions (fields and accompanying structures). On altogether 100 test areas which were implemented in BINATS 1, biodiversity was recorded using the indicators habitat structure, vascular plants, grasshoppers, and butterflies in 2007 (50 test areas in maize cultivation areas) and in 2008 (50 in OSR cultivation areas). A monitoring method was developed in charge of the applicant and her at that time collaborating project team (PASCHER et al. 2009a; 2010a,b; 2011a) and implemented. Now, after a period of ten years biodiversity survey should be repeated in 2017 (maize areas) and 2018 (OSR areas). In contrast to the data set of BINATS 1 which enabled a snapshot of species inventory of plants and selected animal groups, BINATS 2 additionally is able to detect and measure biodiversity trends due to the updated data set. Moreover, wild bees are incorporated into the BINATS monitoring design as an additional indicator. Survey of all indicators is carried out following the methodology described in the BINATS filed guide of PASCHER et al. 2009a & 2010b: Module 1: Habitat structures: singular survey Module 2: Vascular plants: two times survey: spring aspect and late summer aspect Module 3: Grasshoppers: singular survey Module 4: Butterflies: singular survey Module 5: Wild bees: incorporation into the BINATS monitoring design: singular survey of all 100 BINATS test areas in spring; additional triple survey of 30 hot spots of the 100 BINATS test areas during the summer Module 6: Data analyses: -Changes in habitat structures -Changes in species number and abundance of BINATS 1 indicators -Biodiversity trends in the Austrian agrarian regions -For the first time a description of the situation of wild bees in the Austrian agrarian region (regional occurrence, species diversity, abundance) -Pointing out habitat structures which are relevant for the wild bee fauna in agrarian regions and their occurrence in different agricultural land use systems -Survey of the occurrence of neophytes and changes in their abundance within a period of ten years (e.g. Ambrosia artemisiifolia) -Calculation of “extinction debt” and development of measures to save declining species in agrarian regions -BINATS 2 provides the basis for a potential detection of specific effects of genetically modified organisms (GMO) because general agrarian trends over several years are documented for the first time -Identification of ecologically sensible areas in connection with GMO in agrarian regions -Documentation of land use change -Environmental trends -Climate change determined with species occurrence considering average annual (monthly) temperatures and precipitations -Visualising effects of the already finished ÖPUL-programs -If already traceable, success control of single selected measures of the recently implemented Agrar‐Umweltförderprogramm
