Stratosphären-Triops: Im Rahmen des PolAres-Programms wird am 4. Oktober 2008 der Heliumballon "Passepartout" in 30-40 Kilometer Höhe aufsteigen. An Bord: Eier von Triops cancriformis. Nach der Rückkehr wird die Schlupfrate der Eier, die in der Stratosphäre extremen Bedingungen ausgesetzt waren, mit der von unbehandelten Eiern verglichen werden.

Toxizität von BTI an Groß-Branchiopoden: BTI ( Bacillus thuringiensis israelensis ) - Präparate werden an der March zur Stechmückenregulation eingesetzt. Die Toxizität dieses Mittels für heimische Groß-Branchiopoden - prioritäre Leitarten für den Naturschutz in den Marchauen - wurde bisher kaum untersucht. Wir führen nun LC-50 Studien an frühen postlarvalen Stadien folgender repräsentativer Vertreter dieser Tiergruppe durch, von denen zwei gem. NÖ. Artenschutzverordnung geschützt sind: Branchipus schaefferi (Anostraca), Triops cancriformis (Notostraca) und Leptestheria dahalacensis (Conchostraca Spinicaudata).

Stratosphere Triops: In the course of the PolAres-program (Austrian Space Forum), the helium balloon "Passepartout" will be sent to a heigth of 30 to 40 kilometers on october 4, 2008. On board: Triops cancriformis eggs. Back to earth, the hatching rate of the Stratosphere eggs that have experienced extreme conditions will be compared to untreated eggs.

Toxicity of BTI to large branchiopods: BTI ( Bacillus thuringiensis israelensis ) is planned to be used along the Morava river for midge regulation. So far, only few studies have been made on the toxicity of BTI to Austrian large branchiopod species that are prioritary species from the conservationists' point of view. We currently examine BTI toxicity with three representatives, two of them being protected in Lower Austria: Branchipus schaefferi (Anostraca), Triops cancriformis (Notostraca) and Leptestheria dahalacensis (Conchostraca Spinicaudata).
