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".

Ziel der Untersuchungen ist es, spezifische Referenzintervalle für Bullen der Rasse Deutsches Fleckvieh zu generieren. Hierbei sollen Proben aus der V. jugularis externa untersucht werden. Als Probenentnahmezeitpunkt wird die zweite Probengewinnung (vgl. EU VO 2020/686) frühestens 28 Tage (max. 30Tage) nach Einstallung und Beprobung des "letzten" Tieres der Quarantäneeinheit herangezogen, die routinemäßig bei den Tieren aus seuchenhygienischen Gründen genommen wird. Dieser Zeitpunkt ist auch geeignet, um eine Aussage über die endokrine Reife und damit den Zeitpunkt für den Beginn der Spermaproduktion abzuschätzen. Die Werte sollen auch im Hinblick auf die Spermaquantität und -qualität der ersten Sprünge der Tiere ausgewertet werden, um spezifische Grenzbereiche zu etablieren für Bullen mit höherer versus schlechterer Spermaquantität bzw. -qualität.

Project Details:
The precise investigation of the muscle-to-meat transition after the slaughter of farm animals is important, because it (could) lead to a better understanding of the processes during these post-mortem changes. This allows the definition and analysis of influencing factors that may have a positive or negative effect on the meat quality. However, since an in vivo analysis of meat formation is difficult to standardize, in vitro models have been developed that are easier to standardize with regard to metabolites/ compositions (e.g. certain organelles such as mitochondria). Since the models have so far been scientifically investigated in pigs and chickens, the study will first establish an already published in-vitro model with pig muscles and then transfer it to bovine and possibly turkey muscles. These models will then be used to analyze the physiological muscle-to-meat transition after slaughter in more detail, also taking into account certain exogenous and endogenous factors, especially the mitochondria. The influence of mitochondria will be examined in more detail, as they have an (important) influence on meat formation. In addition, the models will be used to analyze (pathological) problems in meat formation (e.g. PSE, DFD).

In order to be able to accompany the evaluation process of the spatial development plan (ROP) from the perspective of marine nature conservation, a nature conservation-based, ecosystem-based planning contribution is to be developed as part of the project, which can be integrated into the marine spatial development plan (MSP) update process in a targeted manner.
In order to enable a synthesis of the information relevant for the planning contribution, the current state of knowledge from completed and ongoing research projects will be researched. Together with additional sensitivity analyses, content for the integration of ecosystem-relevant aspects into the planning contribution will be developed. In addition, various scenarios for the expansion of offshore wind power will be developed and evaluated in order to establish the necessary conditions for an environmentally compatible expansion of renewable energies in the North and Baltic Seas. The project is thus intended to provide an overall spatial planning concept for marine protection that can be incorporated by the BfN into the process of evaluating and updating the MSP.
BioConsult GmbH & Co KG is carrying out the BfN research project as contractor.
The following work on marine mammals is being carried out as a contribution by the TiHo:
- Compilation and preparation of the available distribution data in the form of maps, diagrams and tables with textual explanations
- Identification and presentation of important habitats for indicator species (e.g. harbor porpoise, harbor seal, grey seal)
- Effects of three scenarios of OWP expansion

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.

Avian influenza in humans is associated with pneumonia, inflammation and high case fatality rates. We identified CYP19A1 as a key gene involved in sex-specific lung inflammation in SARS-CoV-2 infected hamsters and humans. CYP19A encodes for the aromatase enzyme that converts testosterone-to-estradiol leading to the activation of various estrogen-regulated pathways associated with lung inflammation. Treatment of SARS-CoV-2 infected hamsters with letrozole, a clinically approved CYP19A1 aromatase inhibitor, recovered impaired lung function and overall lung health in males. We further found that also avian H7N9 influenza virus infection mediates massive upregulation of CYP19A1 in the lung of infected animals. Thus, we hypothesize that estrogen-regulated activation of inflammatory pathways in the lung play a crucial role in severe viral disease outcome. Therefore, in this proposal, we will systemically evaluate the impact of compounds that inhibit the synthesis of estrogens (using aromatase inhibitors) or interfere with estrogen-regulated down-stream pathways (using estrogen antagonists, SERMs, SERDs) against avian influenza in the hamster model. Obtained data will provide new insights into estrogen-mediated inflammatory pathways upon infection with respiratory viruses. Moreover, identification of common pathways might result in overarching drug targets to treat inflammatory lung diseases in general.

The project focuses on the isolation of phages from the feces of bearded dragons. After isolation, phages are examined and classified according to their efficacy and characteristics. Subsequently the influence of phage application on the microbiom and shedding of Salmonella is examined. These examinations are of relevance because of the zoonotic potential of Salmonella shedding in reptiles.
