The impact of artificial lights and anthropogenic noise on Loggerheads (Caretta caretta) and Green Turtles (Chelonia mydas), assessed at index nesting beaches in Turkey and Mexico
(2009-06-02)
Coastal development is considered to be a significant hazard that endangers sea turtles by destroying nesting space. If uncontrolled, it will result in decline and local extinction, or will prevent recovery of these ...
Vom Verhalten zum fiktiven Fressen: Anatomie und Elektrophysiologie des muskulären und neuronalen Systems der Nahrungsaufnahme von Dipteren-Larven (Calliphora vicina, Drosophila virilis und Drosophila melanogaster)
(2010-03-29)
In dieser Arbeit wurde versucht, auf Basis klassischer neurobiologischer Methoden das larvale Fressverhalten von cyclorraphen Dipteren, im Speziellen von Drosophila melanogaster, als Modellsystem für die Untersuchung ...
Identification of a putative Litomosoides sigmodontis phosphate permease, Ls-ppe-1, and its role in the interaction between filarial nematodes and their Wolbachia endosymbionts & Establishment of RNA interference in the rodent filaria Litomosoides sigmodontis, a model of human filariasis
(2009-12-09)
Filariasis is a vector-borne disease that affects 200 million individuals in the tropics, a large number of them seriously, where the disease leads to blindness (onchocerciasis) or elephantiasis (lymphatic filariasis). The ...
Funktionelle und molekulare Untersuchungen zur Expression von GABAA- und P2X-Rezeptoren in Gliazellen des Hippocampus
(2009-11-26)
In dieser Arbeit wurden Membranrezeptoren von Gliazellen des Hippocampus funktionell und molekular untersucht.
Der Fokus der Untersuchungen lag auf der Charakterisierung der GABAA-Rezeptoren in GluR-Zellen. ...

Neurobiology and modeling of cuticular hair sensilla of scorpions: Response characteristics and implications for biomimetic design
(2008)
In this thesis, the neurobiology of mechanoreceptive sensilla on the pectines of the scorpion Pandinus cavimanus was examined. The morphology of the pectines, the innervation and morphology of the sensilla as ...
Nutzung von Telemetrie- und Satellitendaten zur Identifizierung wichtiger Habitate wandernder Vogelarten (Ciconia ciconia, Aquila pomarina)
(2007)
Während ihrer Wanderung nutzen Tiere vielfach unterschiedliche Biome, Klimazonen oder Habitate. Damit sind sie jedoch auch verschiedenen Gefahren ausgesetzt, die insbesondere aus der Vernichtung von Habitaten, Verfolgung ...
Sperm competition in the scorpionfly Panorpa communis (Mecoptera, Insecta)
(2007)
The aim of the present study was to investigate the basal mechanism of sperm competition in the European scorpionfly Panorpa communis. Within three laboratory experiments, I used five newly developed microsatellite ...
Effects of Habitat Degradation and Fragmentation on the Genetic Population Structure of Phytophagous Beetles in an African Rainforest
(2005)
In the presented study the genetic population structure of the phytophagous beetles Amphitmetus transversus (Coleoptera, Curculionidae) and Monolepta vincta (Coleoptera, Chrysomelidae) was analysed in a highly disturbed ...
The homeodomain of the Drosophila Ceramide Synthase Schlank confers nuclear import information and DNA binding capabilities
(2014-05-15)
Ceramide Synthases (CerS) are membrane bound enzymes at the center of the sphingolipid synthesis cascade. A sub-class of CerS also codes for a homeodomain of unknown function.
We previously identified the ...

Ecology and Population Status of the Puku Antelope (Kobus vardonii LIVINGSTONE, 1857) in Zambia
(2014-02-18)
Road surveys along line transects were conducted at different times during the dry season. Puku occurred in small to large groups. They preferred grassland where estimated population densities were 36.15 puku/km² in Kasanka ...
