From 12.04. to 15.04.2023 the "Black Grouse Symposium 2023, Will the black grouse survive in the Lüneburg Heath?" took place at Camp Reinsehlen in Schneverdingen. The event was organized by the Alfred Toepfer Academy for Nature Conservation (NNA), the ITAW, the Lower Saxony Hunting Association (LJN), the Lower Saxony Ministries of Agriculture (ML) and Environment (MU) and the Nature Conservation Park Association (VNP). At the symposium, the alarming state of the black grouse population in Lower Saxony, known and suspected causes of this state and possible solutions were discussed. The participants, in particular the local stakeholders from the areas of occurrence, clearly advocated a species aid program for the black grouse in the Lüneburg Heath, which should provide a framework for eliminating the problems discussed in the best possible way and achieving a healthy, stable population in the medium to long term.

At a follow-up event initiated by the Lower Saxony Ministry of Food, Agriculture and Consumer Protection in June 2023, the project to develop a black grouse action plan was launched. The project is being implemented by the ITAW and the NNA. The contents of the action plan will be coordinated with the involved stakeholders from landowners, authorities and other interest groups as part of a "round table".

We will study the immunogenicity and efficacy of our vaccine candidate, MVA-MERS-S, when used in different single vaccination and vaccination-booster setting in the lethal k18-hDPP4-mouse model after MERS-CoV-challenge infection. Different vaccination schedules also include different time points of challenge infection. We will characterize the activation of MERS-CoV-specific antibodies and T cells. The protective efficacy will be analyzed by morbidity, mortality and viral load in the lung and the brain a target organs. Moreover, a histopathological examination of the upper and lower respiratory tract of the animals upon challenged with MERS-CoV will show any evidence of ADE and ERD, respectively. Another study will evaluate the impact of passively transfered sera from MVA-MERS-S vaccinated mice for the outcome of protection after challenge infection.

The mouflon or mouflon Ovis gmelini musimon only occurs in a few remaining populations in Lower Saxony. The mouflon should have a good chance of survival at least in some low mountain regions due to its predator avoidance strategy with short steep escapes up rocky slopes, but has become extinct in the lowland regions due to the presence of the wolf.
There is much discussion about the few animals in Lower Saxony and Germany in general: The mouflon is not originally native here (not autochthonous) and causes high levels of damage to forestry locally. On the other hand, it is classified as endangered by the IUCN in its native Corsica and Sardinia and is a symbolic species for hunters. Therefore, in this study we want to take a neutral view and use photo traps and direct observations to determine facts about abundance, behavior and enemy avoidance strategies as well as damage effects. In addition, surveys and interviews will be used to obtain the opinions of the various stakeholders (hunters, foresters, farmers, other nature lovers, etc.).
All of this data will be used to objectify the discussion about mouflon, large predators and human interests and to model the survival probabilities of Lower Saxony's mouflon populations in the presence of wolves and lynx.

Epilepsies are frequent neurological diseases in humans and dogs, characterized by recurrent, spontaneous seizures. About one third of human and two thirds of canine epilepsy patients do not become seizure free with the currently available antiseizure medications and are considered as pharmacoresistant. In addition, all antiseizure drugs cause adverse effects. Non-pharmacological treatment strategies are therefore urgently needed, and include therapeutic exercise training as adjunctive therapy.
So far, the effects of moderate exercise training on epileptic seizure thresholds are not sufficiently investigated, although several studies suggest that its positive effects might be therapeutically useful. Our pre-clinical studies focus on the effects of moderate exercise training on epileptic seizure thresholds and behavior.

Measure 1 consists of work package A, which is part of e-learning service. The use of the blended learning format in veterinary teaching is to be promoted. A further focus will be placed on strengthening the (e-)didactic skills of lecturers and the digital skills of students, for which training courses will be created for these target groups.

Measure 1 also includes work package B, which is located in the Clinical Skills Lab. The establishment of a surgical logbook is intended to strengthen students' surgical skills. To support the implementation of the surgical logbook, a training concept for teaching surgical skills is being developed.

Underwater noise from ship traffic, the construction of facilities in the water and on the coast or the explosion of ammunition in the sea is identified as a threat by various national and international expert assessments and has negative effects on marine animals in the Wadden Sea - especially on marine mammals, including porpoises. Many projects on the effects of noise pollution on marine mammals underwater are already being carried out at the ITAW. The ITAW is particularly concerned with the effects of underwater noise on harbor porpoises, with a particular focus on ship traffic, offshore constructions, and unexploded ordnance contaminated sites (e.g. BfN-UWE2, BMBF-COASTALFUTURE, EU project SATURN). In this joint project with BUND, ITAW will provide support with recommendations for measures to reduce the effects of underwater noise on porpoises, development of voluntary rules of conduct, participation in panel discussions and materials for exhibitions. Different target groups should be made aware of the need to reduce underwater noise through different offers (exhibitions, lectures in schools, raising awareness among recreational boat owners). At the same time, recommendations for concrete measures to reduce underwater noise pollution are being developed.

Project Details:
Plastic pollution is now known worldwide and is an omnipresent problem for every ecosystem. In 2021, the annual plastic production was 390.7 million tonnes. A distinction is made between macroplastics (> 5 mm), microplastics (MP; < 5 mm) and nanoplastics (in the nanometre range).
These plastic particles enter the marine environment via various routes, e.g. via wastewater, atmospheric transport, ocean currents, landfills and fishing activities. Once in the environment, macro litter is broken down into smaller particles because the polymer structure is weakened by photodegradation (UV), hydrolysis, mechanical abrasion, biodegradation (microorganisms) or biofouling (colonisation of plastics by microbes).
The polar regions were long considered to be largely unaffected by humans. Even though it is not a heavily populated region, MP has been detected in this ecosystem in a variety of compartments such as the water column, snow, sea ice and deep-sea sediments. The increase in temperature as a result of climate change and the associated melting of ice is causing various problems - in addition to the rise in sea level, the increasing decrease in sea ice is leading to the release of microplastics that were previously bound by the ice deposits. This is now "available" and enters the sensitive ecosystem - the consequences cannot yet be estimated. The presence of microplastics in the Arctic means that species in the polar region are now increasingly confronted with an anthropogenic problem - the presence of marine litter or microplastics and its consequences. This also includes Arctic peoples, whose diet also includes the meat and fatty tissue of marine mammals.
The aim of the project is to obtain valid data on microplastics and associated pollutants in marine mammals from Arctic waters and thus improve the state of knowledge in this sensitive habitat. The acquired knowledge is the basis for future trend analyses that are necessary to enable effective MP monitoring in Arctic waters. The following species characteristic of the Arctic will be studied: harbour porpoise (Phocoena phocoena), ringed seal (Pusa hispida), grey seal (Halichoerus grypus), harbour seal (Phoca vitulina), hooded seal (Cystophora cristata), bearded seal (Erignathus barbatus) and polar bear (Ursus maritimus). Another important aspect is the establishment of a method for visualising MPs in tissue. For this purpose, pieces of tissue from the gastrointestinal tract are prepared and examined both histologically and using a confocal microscope. Various staining techniques are then used to identify potential microplastics in the tissue. This is an important step towards better understanding the transport routes of microplastics and verifying entry paths.
The samples come from various co-operation partners such as the University of Iceland and the Norwegian Polar Institute. The pollutant analysis is being carried out by the University of Siena.

The overall goal of the project is that farms that have high antibiotic use (ABU) can learn from farms that have comparably low ABU and the identification and optimization of parameters to improve animal health. The specific objectives of the project are: to improve biosecurity and overall hygiene of broiler chicken farms, to improve animal health of broiler chickens, to minimize the use of antibiotics, to transfer knowledge between broiler chicken farms with low and high ABU, and to optimize risk areas based on knowledge transfer.
There should be an intensive exchange of experiences between farmers who have different levels of ABU within the project. Thus, farms that have a high need for antibiotic use at the beginning of the project will learn which parameters they can and should optimize to improve animal health and minimize antibiotic use. Farm management factors that have a potential impact on animal health and consequent necessary ABU will be evaluated and collected during the practical phases of the project. These factors are divided into respective work packages (WP), including biosecurity of the farm and hygiene management (worked on by FLI & UROS), cleaning and disinfection (UROS), animal health and stable or herd management (TiHo and LMU), and knowledge transfer (UROS).
The project thus involves farms that have already been able to minimize their antibiotic use through innovative measures, optimized management and improved husbandry conditions. In addition, farms that are interested in improving animal health and minimizing antibiotic use and want to learn from other farms are invited to participate.
