Impact of chemicals on health and the environment
Auswirkung von Chemikalien auf Gesundheit und Umwelt
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Dr. Joseph Schnitzler; Janina Bartels
Duration: October 2020 until January 2021
Funding: Niedersächsisches Ministerium für Wissenschaft und Kultur Volkswagenstiftung, 75.000 EUR
Project Details:
Various studies have already shown effects of chemicals from everyday products on the environment and health. The European Green Deal therefore aims to better assess the risks of hazardous chemicals and in particular very persistent chemicals in a timely manner. Pollution from persistent and mobile chemicals is closely linked to prevailing production and consumption patterns and is determined by the lack of appropriate technical options. These chemicals also challenge regulators to develop and enforce effective policies. The project aimed at increasing knowledge on health and environmental effects on aquatic and terrestrial wildlife. In addition to developing solutions for monitoring, a better understanding of the accumulation of these chemicals in the environment, in line with the EU call with the planned research project, should also help to proactively prevent negative impacts of persistent and mobile chemicals on humans and the environment.
The project serves to build and consolidate a project consortium to ensure the project application and a joint timely application in this EU funding programme. The involvement of many European countries in the project consortium should make it possible to write the project proposal with experienced scientists from the fields of toxicology and health and to submit it on time with an external professional office for EU project applications.
Results:

In the project, a project consortium was established to ensure a project proposal and a joint timely application in this EU funding program. The involvement of many European countries in the project consortium made it possible to write the project application with experienced scientists from the fields of toxicology and health and to submit it on time with an external professional office for EU project applications.

Animal welfare as a dimension of sustainability
Tierwohl als Dimension von Nachhaltigkeit (TiDiNa)
Project Investigators: Kunzmann, Peter; Weber, Tabea Sabrina; Nelke, Andrea
Duration: February 2020 until February 2021
Funding: Landwirtschaftliche Rentenbank, 50.000 EUR
Project Details:
The projects`main question is if, why and how the welfare of farm animals is connected to the idea of sustainability and if animals`interests are playing a role in the present discussions on sustainability.
Results:

In current sustainability concepts, animals and animal welfare are only indirectly addressed in places, although this preliminary study has shown that their inclusion is socially desirable or even demanded. The extent to which the anthropocentric sustainability goals and the welfare of farm animals can be meaningfully linked will be the subject of a follow-up project.

Future Discourses Neozoen - How do we deal with immigrant species - and how do we want to deal with them?
Zukunftsdiskurse Neozoen - Wie gehen wir mit eingewanderten Tierarten um - und wie wollen wir mit Ihnen umgehen?
Project Investigators: Prof. Prof. h. c. Dr. U. Siebert; Dr. Friederike Gethöffer; Franziska Schöttes
Duration: June 2020 until August 2021
Funding: Niedersächsisches Ministerium für Wissenschaft und Kultur, 116.300 EUR
Project Details:
Neozoa are alien or non-native animal species that have been directly or indirectly introduced into a new habitat by humans. Intentional and unintentional introductions pose a threat to biodiversity worldwide. One prominent example is the raccoon. This problem is well known and is taken into account in Germany, for example, in the Federal Nature Conservation Act and the National Biodiversity Strategy. However, it is often unclear how introduced animal species should be dealt with. Prevention is the top priority. The aim is to prevent new species from being introduced and spreading. However, depending on the species and the invasiveness assessment by the Federal Agency for Nature Conservation, animals are also removed and killed. This leads to a conflict between animal welfare, species protection and environmental protection. Although animal-related issues are usually discussed very emotionally, this problem has so far only been partially recognized by the public. For this reason, this area of conflict will be addressed during the project and discussed with various interest groups. The focus will be on two projects of the Institute for Terrestrial and Aquatic Wildlife Research of the University of Veterinary Medicine Hannover Foundation, which deal with the introduction of the nutria, originally from South America.

Hearing Noise: Behavioral and Evoked Potential Hearing Measurements in Aquatic Animals: Hearing and estimated noise impacts in three species of Auk: Implication for the marbled murrelet
Hearing Noise: Behavioral and Evoked Potential Hearing Measurements in Aquatic Animals: Hearing and estimated noise impacts in three species of Auk: Implication for the marbled murrelet
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Kirstin Anderson Hansen
Duration: May 2020 until April 2021
Funding: University of Iceland's Research Center in Húsavík, 43.611 EUR
Project Details:
The aim of this project is to assess hearing abilities and adaptations in marine animals as a part of a broad, comparative study examining how animals use acoustic signals and cues. In cooperation with the University of Iceland?s Research center the hearing of stranded, wild caught and aquarium-housed fishes, birds, marine mammals and turtles will be measured. In order to assist in assessing hearing capabilities and possible impairments, the measurements will be determined in rehabilitation facilities, research facilities and in the field. In addition to aiding treatment decisions, this work will assist the understanding of how these animals use and are affected by ocean noise.

The specific objectives of this study include:
1.Conduct field-based, in-air evoked potential audiograms to address the initial sensitivity, and potential species differences of three Auk species.
2.Establish the in-air psychophysical (behavioral) audiograms of 1-3 Auk species.
3.Establish the underwater psychophysical (behavioral) audiograms of 1-3 Auk species.
4.Compare psychological and behavioral methods, and underwater vs. air results to evaluate the best means to quantify Auk hearing, setting the foundation for future noise-exposure studies
5.Determine the levels at which Auks show temporary threshold shift (TTS) responses to sonar.

Characterization of MVA based candidate vaccines in the hamster model
MVA-basierte Impfstoffkandidaten im Hamster Model
Project Investigators: Prof. Dr. Asisa Volz
Duration: Novemer 2020 until April 2021
Funding: DZIF, 200.000 EUR
Project Details:
Die Impfstoffentwicklung gegen COVID-19 ist von höchster Dringlichkeit, wofür es jedoch zunächst einiger prä-klinischer Experimente bedarf, bevor Studien im Menschen angewandt werden können. MVA-SARS-CoV-2 Impfstoffe sollen hierfür im Tiermodell auf Sicherheit und Immunogenität getestet werden. Dabei soll das Hamstermodell im Vordergrund stehen, da Hamster ein ähnlich aufgebautes ACE-2 Protein exprimieren und sich darüber hinaus schon in der SARS-CoV-1 Forschung als Tiermodell bewährt haben.
