Kaninchen mit Schlappohren, sogenannte Widderkaninchen, erfreuen sich einer zunehmenden Beliebtheit. Durch die Schlappohren sind diese Kaninchen prädestiniert Otitiden zu entwickeln. Im Rahmen von vergleichenden Untersuchungen zu Ohrerkrankungen bei unterschiedlichen Kaninchenrassen (REUSCHEL, 2018) wurde auch eine Verkürzung der Schädel bei diesen Kaninchen festgestellt. Diese beginnende Brachyzephalie bei Heimtierkaninchen könnte eine zunehmende Bedeutung erlangen und sich ähnlich wie in der Kleintiermedizin (Hund und Katze) entwickeln. Daher untersucht das Projekt die Kopfform von Kaninchen anhand von Messungen an CT-Aufnahmen unterschiedlicher Kaninchenrassen im Vergleich zu Wildkaninchen. Außerdem sollen weitere anatomische Veränderungen, welche durch den verkürzten Kopf entstehen können, in Anlehnung an Erkenntnisse von brachyzephalen Hunden untersucht werden.

Das SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-Type 2) ist der Erreger von COVID-19. Der bisherige Verlauf der COVID-19 Pandemie hat nachdrücklich gezeigt, dass eine koordinierte Bündelung von interdisziplinären und komplementären Expertisen notwendig ist, um die vielfältigen Aspekte der Biologie, der Pathologie und der Epidemiologie von SARS-CoV-2 zu entschlüsseln und die gewonnenen Erkenntnisse sowohl klinisch für die Behandlung von Patienteninnen und Patienten als auch für die Modellierung von Infektionsverläufen in der Bevölkerung einzusetzen. Die innerhalb der COFONI Technologieplattform betriebenen COVID-19-Tiermodelle soll dazu beitragen systematisch Daten zu sammeln, zu vergleichen und zu analysieren. Dies soll dazu beitragen, die aus klinischen Studien verfügbaren Daten zu bewerten und den wissenschaftlichen Fortschritt durch In-vivo-Studien kritisch zu reflektieren. Die weitere Verfeinerung und Entwicklung von Tiermodellen für COVID-19 wird zur Entwicklung von Impfstoffen und therapeutischen Wirkstoffen beitragen. Gegenwärtig laufen groß angelegte klinische Studien, in denen mehrere Kandidaten für präventive und therapeutische Maßnahmen am Menschen getestet werden. Die Ergebnisse dieser klinischen Wirksamkeitsstudien werden eine noch nie dagewesene Gelegenheit zur Rückvalidierung und Verfeinerung dieser Tiermodelle bieten.

In addition to antimicrobial molecules, nitrate and nitrite ions are also produced during the generation of PAW. PAW could thus be suitable as a basis of brines for curing meat products. On the one hand, the addition of classical nitrite curing salt could be minimized, on the other hand, the antimicrobial molecules contained in the PAW could have positive effects on the shelf life of the products. As part of the project, a novel production process of wet-cured meat products using PAW will be established and possible positive but also negative effects on the product will be determined.

Project Details:
Harbour porpoises are representatives of the top predators from the group of mammals in the North Sea and Wadden Sea. With the amendment of the National Park Act in 1999, part of the National Park was explicitly dedicated to harbour porpoise protection, as a high density of mother-calf pairs was found there. As part of the reorganisation of the Federal-and State Marine Programme (BLMP), a programme for joint monitoring of marine mammals was agreed in January 2011, which meets the requirements of monitoring according to the relevant European guidelines and international conventions. In this programme, the Schleswig-Holstein National Park Administration (NPV) in the Schleswig-Holstein State Agency for Coastal Protection, National Parks and Marine Conservation (LKN) has the task of organising, implementing and financing the acoustic monitoring of harbour porpoises. The acoustic surveys for the NPV are carried out by the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) as part of the joint marine mammal monitoring under the BLMP. For this purpose, measuring stations are operated at five specified sites in the Schleswig-Holstein Wadden Sea (Lister Tief, Meldorfer Bucht, Rochelsteert, Westerland and Elbe river). The monitoring stations are equipped with click detectors (Cetacean-Porpoise Detectors, C-PODs), which record the echolocation activity of harbour porpoises. The C-PODs are maintained and data downloaded on a regular basis. The data obtained are evaluated for optimising the acoustic monitoring as well as necessary extensions for a permanent operation of the measuring stations.

Results:

For over eleven years, porpoises have been regularly detected at all five measuring stations in the Schleswig-Holstein Wadden Sea, with significant spatial and seasonal differences in detection rates. The highest detection rates were recorded at the Westerland, Meldorfer Bucht, and Elbe river stations, while Lister Tief consistently showed the lowest values. All stations showed a seasonal maximum in spring, with the Rochelsteert and Außenelbe stations showing a pronounced maximum in autumn. This maximum coincides with the mating season and indicates that these regions are used more intensively during the reproductive phase. In the Elbe estuary, the low detections in spring suggest that porpoises follow their prey fish into the rivers and reoccur in the estuary in autumn. In addition to the seasonal patterns, there were also slight area-dependent patterns related to tides and time of day. The long-term data confirms the importance of the Wadden Sea as a key habitat for porpoises and enables robust trend analyses, which necessitate continued monitoring.

We applied for an follow-up financing in order to increase the reach, the attractiveness as well as the functionaliy of the platform. Due to corona this was not possible to a sufficient extent within the originally planned projekt period. The following optimizations are now planned for the top-up phase:
Target group expansion to include interested non-scientists.
Networking of 3R-SMART with established online portals of external partners.
Integration of an area with Open-Educational-Resources.
Integration of a collection of contributions to 3R centers.
Integration of interactive elements into existing contributions.

Ab dem 28.01.2022 tritt das neue Tierarzneimittelgesetz in Kraft, sodass es ab diesem Zeitpunkt immer wichtiger wird, Hochleistungstiere durch optimierte Ernährung gesund zu erhalten. Ziel dieses Projektes ist eine Verbesserung der Eutergesundheit und damit einhergehend der Milchqualität durch den Einsatz von Pflanzenkohle, die mit Vitamin E angereichert wird. Zunächst soll in vitro der Effekt der Pflanzenkohle auf die Fermentation im künstlichen Pansen (RUSITEC) untersucht werden. Basierend auf den Ergebnissen der in-vitro-Studie wird anschließend die Pflanzenkohle bei laktierenden Milchkühen über das Milchleistungsfutter dosiert.

Project Details:
The species group of marine mammals represents a relevant ecosystem component in German marine waters. According to the latest assessment of the Marine Strategy Framework Directive (2008/56/EC, MSFD), marine mammals in the North Sea and Baltic Sea have not achieved good conservation status. Good data bases as well as scientifically robust approaches to assessing status are needed to adopt measures that will subsequently lead to good conservation status for the respective populations of marine mammal species. To ensure that these data are as comprehensive, comparable, and area-wide as possible, regional coordination of monitoring and indicators used for assessment is essential. Because marine mammals are highly mobile species, it is also imperative from a scientific perspective to coordinate and review the implementation of indicators and the effectiveness of monitoring at the international level. In addition, the development of the indicators is an important tool for future research concepts in the monitoring field and requires the results, scientific analyses and approaches to the design of the indicators to be brought into the international process.
The goal of this project is to further develop data-based, regionally accepted indicators for assessing the status of marine mammals in the North and Baltic Seas and to bring them to national and regional agreement. Different approaches to assess the status of biodiversity under the MSFD will be developed, refined and harmonized at international, regional and national levels. They are used nationally as well as regionally and internationally in marine conservation conventions (relevant for Germany: Oslo-Paris Commission (OSPAR) and Helsinki Commission (HELCOM)) by numerous bodies and working groups (e.g. under the International Council for the Exploration of the Sea (ICES)). The cooperation regarding the MSFD and partially the Council Directive on the conservation of natural habitats and of wild fauna and flora will be organised within the framework of BLANO in Germany.
Scientists at the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) of the University of Veterinary Medicine Hannover (TiHo) Foundation have in the past developed or implemented national and international research projects as well as monitoring concepts with a focus on marine mammals, so that long-standing data series, expert knowledge and basic principles for the design of indicators are available and can be incorporated into the process. A continuous cooperation is necessary in the various working groups, in order to guarantee a sufficient incorporation of German research results and indicator concepts on international level. This is enabled within the framework of this project.

The aim of the project is to build up and consolidate our project consortium, to prepare the project application and to ensure a joint application in due time in this EU funding program. The composition of a convincing project consortium with the involvement of many different European countries is quite important. We aim to coordinate for the project as well as to cover important research areas. The deliverables also include contributing to a better overall societal and public understanding of the relationship between biodiversity and ecosystem functioning through education and training (school and marine science, art and citizen science platforms). Therefore, we would like to specifically work with a professional media partner to create a good outreach concept. The proposed project should enable us to ensure the preparation of the proposal with the project partners, to write the proposal with experienced scientists in the field of biodiversity, ecology and health and to submit it on time with the support of an external professional EU project proposal office

Results:

In the project, the preparation of the application was ensured with the project partners. With experienced scientists from the fields of biodiversity, ecology and health and with the support of an external professional office for EU project the application was submitted on time.
