Amphibians worldwide are confronted with a variety of factors causing a rapid population declines. In Schleswig-Holstein, these population declines can also be in otherwise widely distributed species and cannot be explained by structural parameters alone, such as habitat loss and alteration. Other factors influencing amphibians can include toxicological contamination and invasive pathogens. The effects of those stressors on our native amphibians are largely unknown. Furthermore, the extent to which the different stressors interact is largely unknown, although it is assumed that they potentiate each other. In order to implement successful conservation measures in the long term, it is important to identify and evaluate the relevant stressors. Based on preliminary studies carried out at the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) from 2021 to 2023, the project aims to investigate possible stressors for amphibians native to Schleswig-Holstein. This includes the continued monitoring of pathogens, such as fungi originating from Asia (Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal)) as well as Ranaviruses and herpes viruses. In addition, of animal-related data as well as data on habitat-specific factors are collected to be able to explain differences in the occurrence of infectious agents. The collection of habitat-related data includes water quality characteristics (e.g. pH value, water temperature) and analyses of possible contaminants correlation with utilization, structure and surrounding vegetation over the course of the year.
In addition to recording possible stressors and their interaction, this study aims to develop a basis to evaluate habitats in the course of species protection measures such as reintroduction projects.

Project Details:
The North Sea is one of the busiest shipping areas. In order to achieve the EU's climate targets, a massive expansion of wind farms is planned in the North Sea. The North Sea is also a valuable habitat for many species that are threatened by future maritime developments. This also includes the risk of noise pollution. DEMASK aims to encourage maritime decision-makers, spatial planners and industry stakeholders to address the issue of underwater noise by jointly planning scenarios for the future of the North Sea, improving the tools and knowledge to assess noise mitigation scenarios and setting strategic priorities that lead to a well-managed noise landscape.
DEMASK consists of three working groups. The centerpiece (WP1) is the joint scenario planning process. WP1 relies on stakeholder participation and is specifically designed to maximize the uptake of strategic policy priorities for noise mitigation. It defines and assesses the key policy scenarios for noise reduction. WP2 focuses on predicting the future noise situation. Finally, WP3 will carry out risk assessments for biodiversity in the North Sea for alternative action scenarios. Pilot projects will predict the noise scenarios for these alternative scenarios compared to the baseline situation and use these noise scenarios to assess the impacts of noise and the associated risks for indicator species. Risks will be assessed on the basis of sensitivity, distribution, habitat and exposure if the thresholds for the occurrence of biologically significant adverse effects (LOBE) are exceeded at the regional level. This work package is led by ITAW.

Project Details:
Common Eider (Somateria mollissima) is classified as endangered in Europe due to continuous the population declines. Meanwhile, its occurrence along the coast of Schleswig-Holstein has potential for conflict with the culturally established and economically important fisheries.
The methods investigated in the pilot study showed promising effects: the tested eider protection fence effectively protected the mussel lines from feeding damage by common eiders and there were clear differences to control lines that were freely accessible to the eiders. However, the measures have so far only been tested on a small scale. In order to investigate the practicability on a realistic scale, this follow-up project aims to extend the to a larger area and possibly include other deterring methods that have not been used in the pilot project.

The long-term objective is to find practicable methods that are applicable to commercially operated mussel farms and at the same time function in terms of animal welfare or can even contribute to the reduction of bycatch in other areas.

At the same time, necropsies of dead common eiders will be continued in order to provide information on the incidence of disease within the population, identify pathological changes and classify these in the context of the population decline. This includes bacteriological, virological and parasitological analyses. In addition, toxicological examinations will provide information on the animals' exposure to environmental pollutants.

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.

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".

Project Details:
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.

Project Details:
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.
