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 GABA<sub>A</sub>- und P2<sub>X</sub>-Rezeptoren in Gliazellen des Hippocampus
(2009-11-26)
In dieser Arbeit wurden Membranrezeptoren von Gliazellen des Hippocampus funktionell und molekular untersucht.<br /> Der Fokus der Untersuchungen lag auf der Charakterisierung der GABA<sub>A</sub>-Rezeptoren in GluR-Zellen. ...
Eurasian Blackbirds (<i>Turdus merula</i>) and their gastrointestinal parasites: A role for parasites in life-history decisions?
(2005)
Parasites are increasingly being recognized as potent agents of selection. Gastrointestinal parasites, however, have largely been ignored. The aim of the present thesis was to contribute to the still scarce knowledge about ...
Neurobiology and modeling of cuticular hair sensilla of scorpions: Response characteristics and implications for biomimetic design
(2008)
<p>In this thesis, the neurobiology of mechanoreceptive sensilla on the pectines of the scorpion <i>Pandinus cavimanus</i> was examined. The morphology of the pectines, the innervation and morphology of the sensilla as ...
The impact of artificial lights and anthropogenic noise on Loggerheads (<i>Caretta caretta</i>) and Green Turtles (<i>Chelonia mydas</i>), 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 ...
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 ...
Sperm competition in the scorpionfly <i>Panorpa communis</i> (Mecoptera, Insecta)
(2007)
The aim of the present study was to investigate the basal mechanism of sperm competition in the European scorpionfly <i>Panorpa communis</i>. Within three laboratory experiments, I used five newly developed microsatellite ...
Electrophysiological investigations of the anterior and posterior lateral line nerve of the Goldfish, Carassius auratus, to running water and oscillatory stimuli
(2007)
The neural responses of anterior lateral line nerve (ALLN) fibers of goldfish to sinusoidal water motions in still and running water were investigated. In agreement with previous data (Engelmann et al., 2002) two types of ...
Untersuchungen zur Entwicklung des Landschaftsgartens Aggerbogen zum Standort ökologischer Vielfalt unter der Nutzung als außerschulischer Lernort
(2005)
Der Landschaftsgarten Aggerbogen ist ein ehemals landwirtschaftlich und zur Freizeitgestaltung intensiv genutztes Auengelände, das seit seiner Renaturierung als außerschulischer Lernort im Bereich Naturschutz und Umweltbildung ...
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 ...
