Project Details:
The European Atlantic is changing rapidly, and it is essential that neighbouring countries have access to up-to-date robust information on the status of key species and populations so that future monitoring and management can be directed effectively and efficiently to achieve and maintain favourable conservation status of species and good environmental status of European Atlantic waters. The "Small Cetaceans in European Atlantic waters and the North Sea (SCANS)" survey is being planned for summer 2022. The objective of SCANS-IV is to estimate the abundance of cetacean species in shelf and oceanic waters of the European Atlantic through a large-scale multinational aerial and shipboard survey in July 2022. This is the most appropriate survey month because of the higher probability of good sighting conditions, and also to ensure that results are comparable with those from SCANS surveys conducted in 1994, 2005/2007 and 2016 (Hammond et al. 2002, 2013, 2021). Thus, this project will represent the fourth survey in the SCANS series. SCANS-IV will deliver regionally coordinated synoptic surveys in shelf and offshore waters of the European Atlantic. It will generate robust abundance estimates for regularly occurring whale and dolphin species and improve power to detect trends in shelf and offshore species. The outputs of the project are timely for EU Member States obligations for reporting under the Marine Strategy Framework Directive (MSFD Article 8: due 2024) and the next reporting round under the Habitats Directive (Article 17: 2019 - 2024) (where applicable) and allow OSPAR/HELCOM assessments. The estimates are also needed for impact assessments of offshore industries and fisheries.
The project will be achieved through the successful completion of six work packages. The first two WPs (WP1 & WP2) focus on collecting data on cetacean abundance and distribution through implementation of aerial surveys on the continental shelf and shipboard surveys in offshore waters. The data will be analysed in WP3 to generate abundance estimates, trends and perform spatio-temporal habitat modelling. WP4 will consider the long-term security of the large-scale cetacean monitoring SCANS programme in the Northeast Atlantic and propose a governance structure to ensure the continuation into the future. WPs 5 & 6 will focus on dissemination of results, project management and reporting.

Project Details:
The project aims to develope and to evaluate a filtration system that can be used in natural vetilated poultry houses in transistion periods to prevent from AI entries via air. The lifespan of filters, filter efficiencies and the impact of air filtration on the quality of climate in natural ventilated barns are unknown. Therefore, investigations will be conducted at a natural ventilated turkey barn, equiped with a fine dust filtration system.

Project Details:
The Eurasian otter (Lutra lutra) is (re-)expanding in all parts of the German federal state of Schleswig-Holstein (SH) nowadays. As an aquatic mammal, otters mainly inhabit rivers, streams and lakes but also forage along the coastlines. Otters primarily feed on fish, whereas they are considered food generalists and also target amphibians, crustaceans, birds, mammals and other invertebrates. It is assumed that the decline of certain endangeredeD fish species can be linked to the growing otter population. Furthermore, there is an increase in conflicts between fisheries and otter conservation, both nationally and internationally. Therefore, an extensive evaluation of the current conflict potential between the growing otter population, fisheries situation and conservation conflicts between species is needed. This will be covered in the frame of this research project that focuses on fisheries, natural otter habitat and spawning areas of endangered salmonids in comparison:
-Installing wildlife cameras to assess the local abundance of otters
-Dietary analysis to investigate the prey spectrum of otters
-Determination of otter individuals using spraints (genetic fingerprinting)
-Evaluation of a potential conservation conflict between otters and salmonids
-Development of acustic deterrents to protect fisheries from otters
-Analysing reproduction parameters to assess the population health of otters using specimens found dead

Project Details:
Virus emergence and re-emergence is an increasing public health
problem as globalization and climate change promote the spread of
infectious disease. This is particularly true for mosquito-borne
infections as mosquitoes continue to spread to new geographic
regions. Alphaviruses such as Chikungunya virus (CHIKV) and
Venezuelan equine encephalitis virus (VEEV) belong to the group of
mosquito-borne viruses, which cause pathology in humans. The re-emerging CHIKV is causing long-lasting arthritis like symptoms, while
VEEV infection leads to encephalitis. Why the two viruses from the
same family cause pathologies in different tissues, i.e. joints versus
central nervous system (CNS), is unclear to date. This gap of
knowledge is reflected by the fact that few host factors for CHIKV and
VEEV are known. Here we capitalize on our findings that the
phosphatidylserine (PS) receptor T cell immunoglobulin mucin
receptor 1 (TIM-1) and a tetraspanin are host factors for CHIKV. We
hypothesize that (a) VEEV also hijacks PS receptors and tetraspanins
to infect human cells, (b) TIM-1 and the tetraspanin interact with
additional proteins to promote infection with CHIKV and possibly
VEEV and (c) that a subset of these host factors contribute to tissue
tropism of CHIKV and VEEV. To test our hypothesis we will initially
use unbiased state of the art quantitative proteomics methods to
identify entry factors and receptors of CHIKV and VEEV. Next we will
screen PS receptors and all 33 human tetraspanins for their role in
VEEV infection by RNA interference in human cells. TIM-1 and
Tetraspanin associated proteins will be identified by proximity labeling
in conjunction with high-resolution affinity enrichment mass
spectrometry. Finally we will investigate the contribution of the
identified host factors to tissue tropism of CHIKV and VEEV using
proteomics, single cell sequencing and virological methods.
Specifically, we will infect skin organotypic raft cultures and determine
the predominantly infected cell type as well as expression levels of
identified host factors in the susceptible versus refractory cells.
Additionally we will integrate expression data from online repositories
and measure proteomes of relevant cell types including fibroblasts
and neuronal cells. Using feature selection approaches, we will
identify host factors, which likely contribute to the distinct tissue
tropism and pathologies caused by CHIKV and VEEV. These host
factors will be systematically knocked out first in relevant cell types
and then in mice to delineate the contribution to disease manifestation
in vitro and in vivo. Taken together, this research program aims at
providing mechanistic insight into the infection processes caused by
two important human pathogens, CHIKV and VEEV. The results will
help understand disease mechanisms and may ultimately reveal drug
targets for therapeutic intervention with Chikungunya fever and
Venezuelan equine encephalitis.

Project Details:
The decline in insect biodiversity with negative consequences for food webs and the loss of ecosystem services is currently dramatic. The causes of the decline in insect diversity are manifold, the qualitative deterioration of their habitats, whether on land or in water, light pollution, habitat loss, competition from invasive species and environmental toxins are just some of the factors. As part of this pilot project, flowering areas and nesting aids for insects are being created on the grounds of the University of Veterinary Medicine Hannover Foundation. The results of a species inventory serve as the basis for targeted measures to improve the habitat. The optimizations, e.g. the creation of flowering areas with regional wildflowers, deadwood areas and insect nesting aids, are only the first steps.
Through these measures to promote key species groups, such as wild bees and butterflies, other groups of organisms can also be promoted through deadweight effects due to the improved structural offer, in order to achieve a sustainable optimization of the entire TiHo site.
Further steps are planned as part of the project, which will be scientifically supported by Bachelor's and Master's theses. The TiHo grounds, which are near-natural in many areas, already provide important habitats for numerous rare animals and plants in the urban environment. These habitats are to be recorded in detail, protected and optimized. Other planned measures include improving the ecological condition of the Bünte pond in the park, creating an interactive insect trail and an exhibition with measures to promote biodiversity in urban areas.

Project Details:
Bisher existieren in der veterinärmedizinischen Lehre keine 3D- gedruckten Simulationsmodelle für Reptilien. Um die klinische Ausbildung der Studierenden zu verbessern soll ein praxisnahes Schildkröten-Simulationsmodell entwickelt und angefertigt werden. Im Rahmen einer Dissertation soll anschließend evaluiert werden, inwieweit das Modell in der praktischen Anwendung von Studierenden im Rahmen von Wahlpflichtkursen an toten Tierkörpern erfolgreich umgesetzt werden kann.
