Moderne Forschung im "Alten Bahnhof Schapen"
Ecological Field Station
The Institute runs an ecological field station in Schapen near the city of Braunschweig (approximately 60 km east and a bit south of Hannover). The field station is located in a former railway station, an historical building protected by law, at the edge of the European reserve "Riddagshäuser Teiche". The area is designated as a European reserve site because of the large number of bird species that pass through and use the area during migration. The reserve, which contains a pond and canal system that was first built by monks of the Zisterzeinser in the 12th century, provides a multitude of opportunities for ecological field research, including studies in conservation genetics, the biological impacts of electromagnetic fields, limnology, and biodiversity dynamics.

Character-based DNA barcoding: Accurate identification of conservation units in odonatesIntroduction:
There are an estimated 10 – 15 millions species on Earth (Hammond 1992) of which only about 1,8 millions have yet been described. In addition, human impact - e.g. defragmentation or destruction of habitats - results in a steady increasing number of endangered species. Evidently, many species become extinct without having been described. Consequently, the development of tools for the fast identification of organisms becomes a “sine qua non”. “DNA barcoding” has become popular as a rapid and reliable technique for species identification. In addition to morphological keys, a public reference library containing short DNA sequences of all known species should enable scientist to identify specimens quickly and accurately and to discover new species. - Wickenbrock L, Räder W, Schierwater B
Einfluß unterirdischer Wasseradern auf die Ortspräferenzen von Arion rufus (Mollusca) Einleitung:
Der Erdboden ist die Basis eines jeden terrestrischen Ökosystems und Naturschutzgebiets. Ein möglicher Einfluß verschiedener Energiefelder auf die Diversität und Heterogenität der Bodenfauna ist Gegenstand der Untersuchung. Obwohl seit Jahrhunderten der Glaube an eine Wirkung von „Wasseradern“ auf Tiere besteht („Strahlensucher“, “Strahlenflüchter“), fehlt bis heute jeglicher wissenschaftlicher Nachweis. Im Europareservat Riddagshausen untersuchen wir am Beispiel von Ortspräferenzen ausgewählter Versuchstiere die Frage, ob ein Einfluß von „Wasseradern“ auf die Diversität und Abundanz von Bodenorganismen zu belegen ist. |
