Gewässer sind die Lebensadern unserer Landschaft. Sie bestimmen wesentlich das Landschaftsbild und den Naturhaushalt. Eingriffe in die Natur und die naturnahe Kulturlandschaft haben dazu geführt. daß diese Funktionen gestört oder zerstört wurden. Wasserbau und Ökologie standen sich hierbei lange als Gegensätze gegenüber. Das Gesamtkonzept Naturschutz und Landschaftspflege Baden-Württemberg setzt nun das Ziel, Technik und Ökologie in gesamtschaulicher Betrachtung zusammenzubinden. Wesentliche Ziele der Naturschutzpolitik sind - Erhalten und Sichern naturnaher Auelandschaften und - Regeneration beeintrachtigter Gewasser und Auen. Im Rahmen eines Pilotvorhabens "Naturnahe Umgestaltung ausgebauter Fließgewässer", hat das Umweltministerium in Verbindung mit Umgestaltungsmaßnahmen umfangreiche Untersuchungen, Erhebungen und Dokumentationen veranlaßt, aus denen Anleitungen für das künftige Vorgehen gewonnen werden. Die wichtigsten der zwischenzeitlich abgeschlossenen Untersuchungsvorhaben wurden nun im Rahmen des Kolloquiums "Naturgemäße Gestaltung von Fließgewässern" der Fachwelt vor- und zur Diskussion gestellt. In den Fachvorträgen konnten die umfangreichen Ergebnisse der Untersuchungen nur in Auszügen dargestellt werden. Das Umweltministerium wird die Ergebnisse dieser Untersuchungen in weiteren Heften des Handbuchs Wasserbau veroffentlichen. Die Niederschrift dieses Kolloquiums gibt einen Überblick der derzeitigen Erkenntnisse.
This paper describes a first version of the GPS flight recorder for homing pigeons. The GPS recorder consists of a hybrid GPS board, a patch antenna 19*19 mm, a 3 V Lithium battery as power supply, a DCDC converter, a logging facility and an additional microprocessor. It has a weight of 33g. Prototypes were tested and worked reliably with a sampling rate of 1/sec and with an operation time of about 3 h. In first tests on homing pigeons 9 flight paths were recorded, showing details like loops flown immediately after the release, complete routes over 30 km including detours, rest periods and speed.
Flight paths of homing pigeons were measured with a newly developed recorder based on GPS. The device consists of a GPS receiver board, a logging facility, an antenna, a power supply, a DCDC converter and a casing. It has a weight of 33g and works reliably with a sampling rate of 1/s with an operation time of about 3 h, providing timeindexed data on geographic positions, ground speed and altitude. The data are downloaded when the bird is recaptured. The devices are fixed to the birds with a harness. The measured complete flight paths show many details: e.g. initial loops flown immediately after release and large detours flown by some pigeons. We are here presenting 3 examples of flight paths from a release site 17.3 km Northeast of the home loft in Frankfurt. Mean speed in flight, duration of breaks and length of the flight path were calculated. The pigeons chose different routes and have different individual tendencies to fly loops over the village close to the release site.
The Göttingen conference Systematics 2008 is the first joint meeting of the Gesellschaft für Biologische Systematik (GfBS) and the German Botanical Society, section Biodiversity and Evolutionary Biology (DBG), being the 10th Annual Meeting of the GfBS and the 18th International Symposium Biodiversity and Evolutionary Biology of the DBG. The conference programme covers biological systematics in the widest sense and provides ample opportunities for oral and poster presentations on new advances in plant, animal and microbial systematics. This volume brings together the abstracts of invited speaches from the plenary sessions on Progress in Deep Phylogeny, Speciation and Phylogeography, and New Trends in Biological Systematics as well as those of submitted talks and poster sessions.The Göttingen conference Systematics 2008 is the first joint meeting of the Gesellschaft für Biologische Systematik (GfBp. and the German Botanical Society, section Biodiversity and Evolutionary Biology (DBG), being the 10th Annual Meeting of the GfBS and the 18th International Symposium Biodiversity and Evolutionary Biology of the DBG.

The workshop “Transdisciplinary Research on Biodiversity, Steps towards Integrated Biodiversity Research” was organized on 14-15 November 2011 in Brussels by the German-based Institute for Social-Ecological Research (ISOE) in cooperation with the European Platform for Biodiversity Research Strategy (EPBRS) and the Belgian Biodiversity Platform.
The workshop was a follow up of the EPBRS summit “Positive Visions for Biodiversity” organized in November 2010, and its aim was to explore ways to further increase the capacities of transdisciplinary biodiversity research in Europe. It brought together researchers and experts, representatives and decision-makers from European institutions and research funding agencies, as well as members from civil society and the private sector.
Participants discussed and identified in working groups key research topics and the added value of transdisciplinary approaches for three main themes of the “Positive Visions for Biodiversity” summit:
1/ The integration of biodiversity into every part of life
2/ Values and behaviours to a more harmonious way of life
3/ Governance that is more transparent and effective and that balances global and local responsibilities.
During the final plenary panel discussion, participants highlighted recommendations for promoting transdisciplinary biodiversity research:
➢ Scientists have a role to play in raising awareness on the importance of biodiversity as a transdisciplinary issue.
➢ Environmental policy representatives at national and European level have to open up to and interact with other sectors to better advocate for global biodiversity agreements and mobilize more funding for transdisciplinary research on biodiversity.
➢ There is a need for scientists who are interested in comunicating and advocating. The biodiversity community needs people who are able to bridge between worlds, both science and advocacy, to get transdisciplinary biodiversity topics on European research agendas.
➢ Scientific academic training should provide means and opportunities to train these new professionals to become the “in-between” links. Current educational and insitutional frameworks need to be adapted to provide such training and career opportunities.
➢ Innovation should be understood in a broader sense than technology and products with market value. Research is needed on innovative ways to increase sustainable use, recycling of natural resources and learning from natural processes.
➢ The biodiversity community needs to reinforce its identity and build up larger influential groups to be able to advocate more efficiently at national and European levels.
Among the main barriers to developing and implementing an efficient transdisciplinary research on biodiversity issues, the current trends in European research agendas to focus on technological and product oriented research is particularly detrimental. Improving advocacy on biodiversity and the implementation of transdisciplinary biodiversity research will be critical for the next decade to ensure the necessary knowledge for informing political decisions.
