Ziel der Studie ist es, über den Therapienotstand in der Behandlung von Übelkeit als Symptom des Vestibularsyndroms des Hundes hinwegzuhelfen. Während es gute medikamentöse Behandlungsstrategien gegen Erbrechen gibt, wird die damit zusammenhängende Übelkeit häufig übersehen und bleibt unbehandelt. In unserer Studie testen wir daher ein neues Medikament gegen Übelkeit und etablieren einen Biomarker, um sie besser erkennen und objektiv evaluieren zu können.

Results:

The results provide preliminary evidence of the potential benefit of ondansetron in the treatment of nausea, which was present in all examined dogs. Vomiting was only observed in some dogs indicating that nausea can occur separately and should not be perceived only as a preceding stimulation of the vomiting centre.

The present study is exploring the potential of the cold-plasma-technology for the production of meat products without the addition of nitrite curing salt. PPA (= plama processed air) and PAW (= plasma activated water) are used do generate reactive nitrogen species in meat batter which might induce a reddening effect during the production of cooked sausages. Products generated with this novel technology are analyzed for microbiological, sensory and physicochemical parameters after production and after a storage period.

Wir untersuchen den Einfluss von Darm-Organismen auf die Symptome und Komorbiditäten der Epilepsie. Es gibt stets mehr Hinweise darauf, dass die Darm-Hirn-Achse eine wichtige Rolle für die Hirngesundheit spielt. Zur Therapie wird ergänzend einmal tgl. ein Probiotikum gegeben, welches die Lebensqualität verbessern und ggf. Anfälle reduzieren soll, die pharmakologisch nur schlecht kontrollierbar sind.

The population of the native grey seals (Halichoerus grypus) developed well after their protection and subsequent recolonisation of the Wadden Sea. The positive trend of the population poses a challenge from the management perspective. There is an increasing requirement of suitable habitat, which is commonly associated with enhanced conflict potential. A special kind of conflict exists on the Heligoland Dune, where the largest grey seal colony occurs in German waters. Individual animals habituated to human presence due to spatial density and the continuous close contact between humans and animals and therefore do not display the expected escape reflex anymore. This involves an increased risk potential for swimmers, especially in the water. This study aims to test specific management measures in order to create a swimming area safe for people and to implement them officially if successful. On that account, an acoustic method shall be tested, which has not been used for that purpose yet and is based on the so called startle reflex. In contrast to conventional acoustic devices scaring off seals unspecifically, a very specific signal will be used, which has got no extensive negative effects on target and also non-target species in theory. The study investigates if the application of this system has got the desired efficiency and causes no evident negative effects in this special context.

Results:

Within the framework of the project work already carried out, it has not yet been possible to achieve the targeted goals, as unexpected problems have arisen during data collection in the field. Considering the importance of this system for the community of Helgoland, as well as for the acceptance of grey seals by the inhabitants and guests of Helgoland, it would be important to complete this started experiment. Through a desired project extension, an objectively evaluable data basis should be created, wherewith the acoustic deterrence system can be evaluated.

Der Verantwortungsraum von Berater/Innen wird bestimmt und Empfehlungen an die Hand gegeben, wie eine verantwortungsbewusste Beratung konkret umgesetzt werden kann. Es werden Konzept und Material für Fortbildungsangebote entwickelt, die zum einen Verantwortung von Berater/innen verdeutlichen und zum anderen auch die tierethischen Aspekte in der Beratung vermitteln.

Variation in biological traits is universal in natural populations and has significant evolutionary and ecological consequences. Behavioral traits or combinations of traits are important as they may affect the survival and reproductive success of individuals. Studies have shown that animal personalities and behavioral traits covary with ecological conditions, dependent on the state of the individual, and can be maintained by frequency dependent selection. Animal personalities have been often been classified along five behavioral axes, namely, shyness-boldness, exploration-avoidance, activity, aggressiveness, and sociability. Some studies have shown that amphibians display personality and behavioral traits. However, implications of animal personality in ecological context remain largely unexplored in amphibians. Neotropical poison frogs are toxic and diurnal amphibians with highly evolved parental care and territorial behavior. In this study, we will investigate behavioral traits and personality of the strawberry poison frog within and between populations that differ in their anti-predator strategy (level of aposematism). Therefore, we will examine variations in exploratory, risk-taking and aggressive behavior by running standardized laboratory-based trials on wild-caught adult O. pumilio. Each frog will be tested in three behavioral trials, with the following sequence: exploration, risk-taking and aggressiveness. Within a population, we expect individuals present variations in behavioral traits and personality, and that behavioral traits might be correlated (syndrome). Among populations we expect more aposematic frogs (brighter coloration, higher toxicity) to be more explorative, bold and aggressive than less aposematic frogs.

In der Vergangenheit sind zahlreiche Belastungstests beim Hund zum Einsatz gekommen. Hierbei handelt es sich meist um Adaptionen von Tests, die beim Menschen eingesetzt werden. Unter anderem wird in diversen Studien der 6-Minute-Walk-Test verwendet. Bei diesem Test wird die Strecke gemessen, die ein Patient im Rahmen von 6 Minuten zurücklegen kann. In einem Forschungsprojekt soll nun die Aussagekraft und Zuverlässigkeit dieses Tests mit der eines standardisierten, laufbandgestützten Belastungstests verglichen werden.
