Host-parasite genotype (Gh x Gp) interactions and identification of genetic mechanisms underlying the host-parasite interface in liver fluke (Fasciola hepatica) infected dairy cows
Analysen zu Wirt-Genotyp x Endoparasit-Genotyp (Gw x Gp) Interaktionen in mit dem großen Leberegel (Fasciola hepatica) infizierten Milchkühen und Identifikation der zugrundeliegenden genetischen Mechanismen
Project Investigators: Prof. Dr. C. Strube, PhD; M.-K. Raulf, PhD
Duration: Beginning 2021 until End 2025
Funding: DFG, 491.000 EUR
Project Details:
The aim of the project is to analyse host-parasite interactions between the Fasciola hepatica as parasite and dairy cows as host, taking into account the genome of both interaction partners. Until now, studies on endoparasite resistance have focused exclusively on the genome of the host or the parasite, without considering genotype-genotype interactions between these two players. Therefore, for the first time, interactions will be modelled considering bovine genotypes (Gh) and F. hepatica genotypes (Gp).

Funding for the development of the COVID-19 research network Lower Saxony
Förderung für den Aufbau des COVID-19 Forschungsnetzwerk Niedersachsen
Project Investigators: Prof.in von Köckritz Blickwede
Duration: January 2021 until December 2025
Funding: MWK über Uni Göttingen, 8.400.000 EUR
Project Details:
SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus Type 2) is the causative agent of COVID-19. The course of the COVID-19 pandemic so far has emphatically shown that a coordinated bundling of interdisciplinary and complementary expertise is necessary in order to decode the diverse aspects of the biology, pathology and epidemiology of SARS-CoV-2 and to use the knowledge gained clinically for the treatment of patients as well as for modeling the course of infection in the population. In order to be able to provide and implement such a holistic approach, the federal state of Lower Saxony offers ideal conditions with its internationally renowned science locations. We are therefore applying for financial support for collaborative research to set up a COVID-19 research network in the state of Lower Saxony (COFONI).

Arctic marine mammals in a time of climate change- a Kongsfjorden Case Study ("ARK" - Arktiske Klima forandringer Konsekvenser)
Arktische Meeressäuger in Zeiten des Klimawandels - eine Fallstudie im Kongsfjorden
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Dr. Luca Aroha Schick; Dr. Kristina Lehnert; Joy Ometere Boyi
Duration: April 2021 until 2025
Funding: Nordic Research Council (NRC), 49.000 EUR
Project Details:
The retreat of sea ice and the melting and retreat of tidewater glaciers are particularly visible signs of the changes taking place in the Arctic due to global warming. The deterioration of these two physical features of Arctic marine systems is occurring faster in the northern Barents Sea than elsewhere in the circumpolar Arctic, making the Norwegian High Arctic an indicator of climate change in the Arctic region as a whole. The changes will undoubtedly have profound effects on marine ecosystems in the High Arctic and consequences for endemic Arctic marine mammal species.
The ARK research programme will use a variety of data time series (occurrence, ecology, diet, contaminant levels, health parameters, infectious diseases, trophic interactions, etc.) to quantitatively assess different hypotheses on climate change impacts on Arctic marine mammals: 1) Habitat decline will lead to declines in ice-dependent species, changes in distribution patterns and, in the long term, species extinction. 2) Endemic species will increasingly compete with temperate species, which are expanding their habitats. 3) Exposure to new pathogens and increased levels of pollutants will have a negative impact on endemic species. 4) Atlantification of food webs will negatively impact Arctic species and affect the entire Arctic ecosystem.
Within the ARK project, the Kongsfjord, on the west coast of Spitsbergen, will be used in a case-study approach to investigate changes in the ecosystem, apply physical-biochemical food web models and complex risk analyses to make predictions and provide management information.

Project Details:
Das SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-Type 2) ist der Erreger von COVID-19. Der bisherige Verlauf der COVID-19 Pandemie hat nachdrücklich gezeigt, dass eine koordinierte Bündelung von interdisziplinären und komplementären Expertisen notwendig ist, um die vielfältigen Aspekte der Biologie, der Pathologie und der Epidemiologie von SARS-CoV-2 zu entschlüsseln und die gewonnenen Erkenntnisse sowohl klinisch für die Behandlung von Patienteninnen und Patienten als auch für die Modellierung von Infektionsverläufen in der Bevölkerung einzusetzen. Um einen solch holistischen Ansatz leisten und umsetzen zu können, bietet das Bundesland Niedersachsen mit seinen international renommierten Wissenschaftsstandorten ideale Voraussetzungen. Das Forschungsnetzwerk COFONI arbeitet am Aufbau eines COVID-19 Forschungsnetzwerkes des Landes Niedersachsen (COFONI)um gebündelt Forschungsvorhaben zur Entwicklung neuer Strategien zur Bekämpfung von COVID-19 zu entwickeln. Hauptfokus der Technologieplattform Tiermodelle ist der Aufbau von Tiermodellen für COVID-19.

The soil fauna of the nature reserve Riddagshausen (Braunschweig): Comparison of three biotope types: Are there first indications of an effect of increasing soil drought?
Die Bodenfauna des Naturschutzgebiets Riddagshausen (Braunschweig): Vergleich dreier Biotoptypen: Gibt es erste Anzeichen für einen Effekt bei zunehmender Bodentrockenheit?
Project Investigators: Bernd Schierwater; Jörg-Alfred Salamon
Duration: 2021 until December 2025
Project Details:
In this 5-year monitoring-study the density, diversity and community structure of Collembola and Mesostigmata of three different biotope types (oak-hornbeam-mixed forest, drainage ditch (edge), wet meadow) are investigated in the nature reserve Riddagshausen, a Flora-Fauna-Habitat (FFH) area characterized by a small scale mosaic of different habitat types like ponds, meadows, farmland and mixed forests. In each of the biotope types 10 sampling points spaced at least 20 m apart from each other were selected at random. Large spacing was done to avoid spatial autocorrelation, samples therefore were assumed to be independent.
Starting in March 2021 ten soil cores (diameter 5 cm) were taken at each of the biotope types (one soil core per sampling point). The cores were subdivided into two horizons (litter layer, 5 cm mineral soil). The soil cores were used to extract Collembola, Gamasida and soil macrofauna using a modified high gradient canister method (Macfadyen, 1961; Schauermann, 1982). Collembola and Mesostigmata were determined to species level.
Moreover, Collembola species were aggregated into three different functional groups according to their vertical distribution (epedaphic, hemiedaphic, and euedaphic). These groups differ in their dispersal ability and other attributes such reproduction, mobility, metabolic activity and feeding behaviour.
This sampling and identification pattern will be repeated every year (2021-2025) in early spring (March/April).
We expect changes in the soil fauna communities of the investigated biotope types due to strong differences in the amount of precipitation between the years.

VetAmUR: Veterinary Antimicrobial Monitoring of Usage and Resistance in German Livestock
VetAmUR: Veterinärmedizinisches Monitoring der Anwendung von Antibiotika und des Auftretens von Resistenzen bei Lebensmittel liefernden Tieren in Deutschland
Project Investigators: B. Rehberg; C. Bonzelett; M. Hartmann; Prof. Dr. L. Kreienbrock
Duration: July 2021 until December 2025
Funding: Bundesinstitut für Risikobewertung, Berlin, 413.140 EUR
Project Details:
The project VetAmUR (Veterinary Antimicrobial Usage and Resistance) is a research project that, following the VetCab-S project, is carried out to describe the use of antimicrobials in farm animals in Germany as well as connect this with resistance data for those antimicrobials.

Background: Despite many independent investigations, no direct link between the information on antimicrobial usage and antimicrobial resistance could be estab-lished in German livestock husbandry so far. Therefore, an extensive and detailed risk assessment in regards to antimicrobial resistance is not possible, even though such an assessment is required on an international basis (Global Antimicrobial Re-sistance Surveillance System - GLASS, https://www.who.int/glass/en/). To accom-modate this demand, the VetAmUR project was initiated.

In the area of resistance data, the focus is on collecting data at farm level and de-scribing its heterogeneity with the aim of creating a standardised documentation template.

Additionally, specific periods within the fattening process and specific indications for antimicrobial administrations are documented and observed closely to deter-mine alternative treatments and prevention strategies.

Cold storage of boar semen for the reduction of antibiotic use: From lab to field [CoolSperm]
Kältelagerung von Ebersperma zur Reduktion von Antibiotika: Vom Labor in die Praxis [CoolSperm]
Project Investigators: Prof. Dr. Dagmar Waberski; Dr. Anne-Marie Luther
Duration: December 2021 until January 2025
Funding: Bundesministerium für Ernährung und Landwirtschaft, 224.100 EUR
Project Details:
The aim of the project is to transfer an innovative concept for cold-storage of liquid preserved boar semen into practise. This enables the reduction of antibiotics in the preservation medium and additionally, the optimization of the transport logistics of the semen portions from semen collection centers to the sow farms. The environmental impact resulting from antibiotic use is reduced and possibilities for efficient use of boar semen are tested in practice. Thus, the CoolSperm project particularly promotes sustainability and efficiency in future-oriented pig breeding.
