Project Details:
Marine environment is affected by noise pollution from human activity. The difficulty of conducting clinical and pathological analyses on living organisms in the marine environment and the wide diversity of sources of noise pollution determine a great uncertainty in the nature and extent of effects noise pollution has on marine fauna. Despite the growing literature on these themes, there are still relevant gaps, and a lack of multidisciplinarity in investigations of acute and long-term exposures, considering both single animals and populations. DIAPHONIA will bring together scientists from diverse backgrounds, to assess the various impacts of underwater noise on marine organisms throughout the food web, on European basins. Work package 1 (WP1) will develop a possible diagnostic fingerprinting composed of several tissue markers incorporating molecular, metabolomic and microscopic techniques to identify functional and morphological changes in the acoustic pathways of invertebrates, fishes and marine mammals. WP2 will explore the relationship between behavioural and cellular/molecular/organ effects of both short and long-term noise exposure in fish from different European ocean basins. WP3 will gain insight into the morpho-functionality of the peripheral hearing apparatus in marine mammals and its role in defining the animal?s acoustic sensitivity, by developing a standardised workflow for wave propagation in the associated tissues. All Information and data obtained will be discussed with relevant stakeholders and policy makers, to adapt to a multidisciplinary and evidenced-based approach to the existing guidance. They will also be summarised in guidelines harmonising future research efforts towards novel approaches as predictive models and organoids.

Project Details:
In the previous four years a concept was developed to perform standardized necropsy and examination on all otters found dead in Schleswig-Holstein (SH), to allow for assessment of the general population health status. Even though most otters were roadkills and seemed comparatively healthy, zoonotic agentswere cultured from tissue samples and rare otter specialist parasites were recorded for the first time in Northern Germany. Combined dietaryanalysis includinghard part analysis and genetic metabarcoding were used to depictthe natural prey spectrum of otters. Knowlegde on the otters` diet is of utmost importance in various context, for example in the light of fisheries-otter conflicts. Cementum aging reveiled a rather young average age of the investigated otters from SH. Combined with the ongoing recolonization of the otter in SH, this might be an indication that the population has not finally established itself yet and we face a dynamic process. The findings of various environmental contaminants of concern in the otters from SH were of utmost importance and included potential microplastic particles, pharmaceuticals, rat poison, mercury or per- and polyfluorinated chemicals.

The aim of this project is to combine the expertise from previous years and transform the health assessments into a long-term post-mortem population health monitoring for otters in SH. As top predators, Eurasian otters are indicator species for environmental contaminants or infectious diseases in freshwater ecosystems, like marine mammals in their habitat. By adopting this indicator function, the collection of otter health data shall be continued to allow for the estimation of time trends in future population health assessments. Accordingly, otters found dead in SH will continued to be collected and investigated, including diagnostics such as histology, microbiology and parasitology. The main focus will be on diseased animals and such, where the cause of death is unclear. All other individuals will be screened for relevant indicator pathogens, including distemper virus or high pathogenic avian influenza virus. In addition, parasitological and microbiological investigations will be conducted if assumed necessary. To determine whether hard ticks infecting otters play a role in the transfer of vector-borne disease, all collected hard ticks (Ixodes) from previous years will be determined on a species level. The results will give an overview, which tick species are infecting otters and if the transfer of certain pathogens might play a role here.

In accordance with their role as indicator species of the aquatic environment, systematic mercury analysis will be conducted for the first time on otters from SH. An international collaboration within the EU investigated contaminants in otters and could show that mercury levels in some individuals from SH were very high compared to other top predators. For the planned analysis, samples from the biobank will be carefully selected to ensure a good coverage with regards to age, sex and location of finding. Moreover, first steps to develop biomarkers for environmental contaminants in otters will be made.

Eine systematische Fortführung der Untersuchungen der Fischotter in SH ist von zentraler Bedeutung, um langfristige Populationsentwicklungen einzuschätzen und beurteilen zu können. Als streng geschützte Art und wertvoller Indikator für das Ökosystem Süßwasser bietet ein strategisches Monitoring des Fischotters die Möglichkeit, Arten- und Naturschutz zu verbinden. Auch im Hinblick auf sich abzeichnende Interessenskonflikte, z.B. mit der Fischerei, kann eine solide Datengrundlage zum Fischotter wertvolle Informationsarbeit leisten und sachliche Diskussionen ermöglichen.

In order to estimate and evaluate long-term population trends of otters in SH, a systemic continuation of the post-mortem investigations is needed. As strictly protected species and suitable indicator for the freshwater ecosystem, a strategic monitoring of Eurasian otter represents a valuable tool to combine conservation of both wildlife and nature. Especially when looking at potential conflicts like the otter-fisheries interface, a well developed dataset on otters will help to create information based on scientific facts and ensure objective rather than emotional discussion.

Project Details:
Sounds from offshore wind farms (OWF) are among the main contributors of anthropogenic noise to the marine environment. Substantial effort has been expanded on understanding possible impacts of noise resulting from the development stages of the OWF lifecycle. Despite 30 years of OWF operation in EU waters, our understanding of the impacts in the operational phase on marine ecosystems is limited. In this consortium, we aim to address this gap by expanding our knowledge of the radiated noise and the biological consequences of these operations and placing them in appropriate regulatory contexts, including provisions for adaptive mitigation advice. From the source and medium side, we will quantify key features of radiated noise from fixed and floating OWF, to increase understanding and simulate cumulative effect of clusters on radiated noise, helping us to identify sensitive habitats in cross-basin soundscapes. From the biological perspective, we will identify spatial and qualitative use of operating OWF by top predators and study the impacts of OWF noise on zooplankton behavior. These efforts will advance our knowledge of acute and cumulative effects of operational OWF noise across pelagic food webs. Harmonising and combining these two sides, we will develop knowledge and tools for integration of all aspects of noise production and propagation from operational OWF. This will facilitate assessment of planned OWF expansion for marine spatial planning and environmental impact. Finally, we will synthesise knowledge and best practices from EU and international experiences with fixed offshore wind installations and transfer this into the development of policy, mitigation, and regulation for the floating OWF within national, EU and international frameworks. With expected substantial expansion in OWF infrastructure globally as part of the green shift, our data and approaches will help facilitate this transition while minimizing impacts on the marine ecosystems

Project Details:
The future region "TiPP" has the aim of optimising transparency and traceability in a regionally established value chain pig via digital strategies from farm to fork. The focus of the practical trials is the use of Self Sovereign Identity (SSI) with its concepts and technologies (DLT, blockchain), which is completely unexplored in farm animals. For testing and the later derivation of transparency indices for consumers, animal, farm and process data are collected along the entire pig value chain in sub-projects that address current transparency-relevant areas such as data management, application of sensors, animal health, animal welfare, climate efficiency, sustainability and consumer behaviour.

The objective of this project is to reduce the use of antibiotics in broiler fattening by on-farm hatching. Onfarm hatching is intended to increase animal health and consequently reduce the incidence of bacterial diseases in the flocks. For this purpose, various parameters that can be influenced by on-farm hatching are
taken into account, collected, evaluated and made available to the practice.
The project is divided into two phases. In phase 1, four farms are accompanied that already use the method of on-farm hatching and thus have previous experience (lighthouse farms). The experiences of the lighthouse farms as well as the data collected in this first phase will be passed on in phase 2 as knowledge
transfer to six farms (two with fast-growing broiler, two with slow-growing broiler and two organic farms),
that are using on-farm hatching for the first time (newcomers).

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.

In this project, we hypothesize that glycosylated C-type lectin receptor (CLR) ligands induce a differential expression of CLRs by intestinal macrophages under bacterial dysbiosis, thereby leading to a modulated host immune response. This hypothesis will be tested by performing in vitro and in vivo studies.
