Project Details:
The focus is on the problem that we classify animals according to human standards, such as those we love and those we fight against. Protecting humans from diseases that originate in the animal kingdom requires measures that are maximally detrimental to animals. The retreat weeks will focus on current and controversial research into zoonoses. Ethics and moral philosophy must also provide answers to the question of what boundaries we should draw for ourselves in these difficult decisions and what criteria we should use as a basis. The results are to be bundled into a model that can be used both as a model for questions in the scientific community and as a touchstone for academic discourse on an appropriate relationship to the "animal"

Results:

Triggered by COVID-19, zoonoses have moved into the spotlight of public interest.

In zoonosis research in particular, it is important to weigh up the potential benefits for humans against the actual harm to laboratory animals.

During a retreat week, experts discussed and prepared helpful contributions on conflicts in the field of "zoonosis research on companion animals". Based on real case constellations, an argumentative path through the numerous value contradictions was shown, which represents an extreme condensation of fundamental animal ethical conflicts based on real, concrete scenarios.

The project initially dealt with the clarification of terms: what makes an animal a laboratory animal, what makes it a pet? Where do the terms overlap and what is the legal situation in different countries?

The special nature of companion animals in the context of zoonoses was explored in an ethical and scientific manner. Younger researchers in particular were confronted with the ethical aspect of zoonosis research for the first time and found an ethical exchange on the topic very helpful.

The results of the project were documented in the special issue of the Journal of Applied Animal Ethics Research published in fall 2023 and provide a good basis for a refined model for future interdisciplinary writing projects. A continuation of the project from summer 2024 in the form of European summer schools is planned.

All recombinant RSVs (rRSVs) will be rescued in HEp-2 cells infected with MVA-T7 via transfection of the appropriate full length BAC clone along with either the RSV-B17-058221 and RS V-B18-002094 helper plasmids. All rescued viruses will be analyzed by NGS at passage 3 to identify if any mutations occurred during in vitro passaging. If mutations are identified then COMPANY and INSTITUTION will discuss the
requirement for growth of additional independent rescued viruses, with the COMPANY responsible for the final decision.

Wildlife losses are a commonly recognized problem when mowing land for forage and silage production. Although the causes and rates of loss for individual wildlife species are fairly well quantified, the effects of mowing on medium- or long-term population trends have been little studied. This is especially true in light of the increasing cultivation of bioenergy crops in two-crop systems in traditional cropland areas and in areas with intensive grassland management in recent years.
Against this background, it is urgently necessary to look for pragmatic ways of reducing wildlife losses that can be integrated into agricultural work processes by simple means and that promise a high degree of effectiveness. The present concept is based on the use of acoustic game deterrents or sirens, which, for example, attached to a mowing vehicle can lead to the startling of animals present in the mowing area. In order to effectively design such a game deterrent system, it is first necessary to gather the basic theoretical knowledge. In later follow-up projects, this information can be used to develop a practical game siren. The aim of the present study concept is to develop the basics for an acoustic game deterrent in the following work packages. The work packages a and b are designed as literature research :
a. Literature search and presentation of the audible range of target species, i.e., what frequency ranges and sound intensities appear most promising for acoustic game deterrence.
b. Literature search on sound propagation in agricultural areas.
c. Sound measurements in grassland: Here, the sound pressure of suitable frequencies at different heights and distances to the emission source as well as in different dense grass stands will be analyzed in a simple experiment. Since the focus of the study is in Western Europe, the following animal species are defined as target species in the literature study:
° roe deer,
° brown hare,
° wild rabbit,
° pheasant,
° partridge,
° mallard duck
° meadow birds (e.g. lapwing, curlew, oystercatcher)

The aim of this project is to compile the key statements from the literature published since 2009 on the subject of the influence of predation on selected small game species, meadow birds and other types of agricultural land. In addition, an overview of species protection projects in Germany over the last 15 years and the species mentioned is created, with special consideration of projects that are only known locally/regionally. The reason for this study arises from the fact that many species of open land, including those of wet grassland, have seen continuous and sometimes significant population declines in recent decades. This is often explained by the change in our cultural landscape. The focus here is on the changes in agricultural management forms in recent decades, as well as the general disappearance of suitable habitats, for example due to the cultivation of original habitats such as marshes, lowlands and moors and the wide and open wet grassland. In addition to the necessary programs for the conservation and improvement of these habitats and the habitat quality, the factors of predation influence and predation management deserve just as much attention. Numerous studies confirm this importance. The predation is to be placed in a close reciprocal relationship with the habitat and the weather. Optimum weather conditions and high-quality habitat enable high rearing rates and low mortality rates, so that losses by predators can be compensated. However, under today's often suboptimal habitat conditions in our cultivated landscape and an additional high density of predators, it is not possible to achieve sufficient rearing rates to stabilize the corresponding populations.The aspect of habitat quality is given more consideration in more recent studies than in the studies up to 2009. In addition, there are the results of a number of species protection projects that have not yet been scientifically published, but which undoubtedly provide valuable information for dealing with the predation issue.

There is an increasing concern on the effects of underwater noise on hearing of cetaceans. However, cochlear frequency maps (i.e. distribution of frequencies along the cochlear spiral within the inner ear) are still lacking for marine mammal species. The aim of this study is to predict the cochlear frequency map for harbour porpoise (Phocoena phocoena), based on morphometrics of the sensory cells of the organ of Corti (hearing organ). Once the map for a species is known, it will be possible to identify the frequencies that are impaired once lesions are found in the inner ear, and have better understanding of the consequences for individual to have a hearing loss in a particular hearing range. In cases of noise-induced hearing loss, it will be possible to extrapolate the characteristics of potential sound sources that have triggered a damage. This map will be a crucial tool for management of the effects of underwater noise on hearing in porpoises, as well as improved decision-making in conservation plans for harbour porpoises and other marine mammals.

Im Rahmen dieses Projektes werden Wissenschaftlerinnen und Wissenschaftler mit verschiedenen Interessensgruppen in den Diskurs treten, um die Akzeptanz potentieller Alternativen zu herkömmlichen Proteinquellen zu erfragen, da diese für den späteren Einsatz als Lebensmittel von entscheidender Bedeutung ist. Der Fokus wird hierbei auf Insekten liegen, da deren Verzehr wahrscheinlich eine größere Herausforderung darstellt als der pflanzlicher Proteine. Ziel des Projekts ist es, die Verbraucherwünsche und -erwartungen sowie die Einstellungen gegenüber neuartigen Lebensmitteln besser zu verstehen und einzuordnen.

Project Details:
Suboptimal availability and quality of drinking water as well as a lack of hygiene in water pipes on pig farms can cause animal welfare and health problems. Insufficient water intake due to technical deficiencies, low palatability due to e.g. biofilm formation in the pipes or a restrictive water supply represent a massive stressor for animals and can lead to health impairments that promote other diseases (e.g. ear and tail injuries, diarrhea).
In this project, a new drinking water pipe cleaning concept for piglet rearing farms will be established and tested for practical use in two rearing barns. The system, developed in a collaborative project and tested under laboratory conditions, will be used to clean water pipes contaminated with plaque, to destroy Salmonella reservoirs in the pipes, and to reduce endotoxin contamination. It is exspected, that ear and tail lesions will be reduced after cleaning the drinking water pipes in case that they are related to endotoxins. After technical, chemical and microbiological analyses, as well as examinations of the piglets, the drinking water pipe cleaning is carried out on the farms. A newly developed mobile flushing device and a new substance containing tartaric acid and catalytic additives are used. The substance is highly effective against biofilms and also destroys the genetic material of pathogens. The effects of this cleaning concept will be measured and evaluated on two farms in three baches respectively.
