With CLIMAQUA an innovative process for the conversion and recycling of aquaculture side streams to feed based on A. platensis is created, which in turn can be used in aquaculture. The aim is to significantly reduce the high greenhouse gas emissions from aquaculture, especially for feed production, by integrating A. platensis into biomass / feed production. Geographical and site-specific features (temperature, length of daylight, etc.) are taken into account in order to obtain an almost completely digestible algae-based feed for salmon and catfish farming and thereby establish a circulatory system that is economically and ecologically sound. In addition, CLIMAQUA examines climate change-related aspects of aquaculture in two regions of the world: The use of innovative technologies in aquaculture is adapted to the climatic conditions and promotes the implementation of sustainable and local food systems.

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.

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.

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.

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.

The goal of this project is to reduce the environmental pollution caused by the entry of antibiotics and resistant bacteria from pig breeding. Worldwide, antibiotics are added to liquid preserved semen portions in order to inhibit bacterial growth during semen storage.The present study aims to establish an innovative concept to eliminate bacteria without using conventional antibiotics. The concept is based on the photodynamic inactivation (PDI) of bacteria. Specifically, the aim is to inactivate microorganisms in boar semen using the photodynamic effect and, thus, to avoid bacterial growth and
exchange of resistance genes in the environment.

In this project, the focus is on analysing the interrelationships between animal welfare and environmental protection in dairy farming. The aim of the project is to consider the three factors "low emissions, high walking comfort and long-lived cows" in a three-year study phase in the Chamber of Agriculture's trial barn at Haus Riswick.

The objective of WP3 is to combine the broad expertise of consortium partners in drug discovery in order to identify small molecule candidate drugs to fight coronaviruses.
To effectively deliver drug candidates, WP3 is interacting closely with WP1 and WP2 to identify and select potential starting points for further development based on clearly defined progression criteria. A screening cascade for (phenotypic) hit ID has been implemented and executed. In addition, a coordinated AI-platform and analysis of targets for their druggability is being finalized to facilitate the selection of potential starting points for chemistry. The medicinal chemistry efforts have not yet been initiated as the review and selection of potential starting points from the first wave of hit identification is still ongoing.
In addition to the Hit selection criteria to move forward into Hit to Lead (H2L), WP3 contributors have already prepared for the next steps by defining the initial progression criteria for hits, leads and optimized lead compounds. In addition, a screening cascade for H2L and lead optimization (LO) is proposed, including the flow for the ADMET-PK related assays. The aim is to work towards the predefined target product profiles (TPPs) which have also been discussed within WP3 and are close to finalisation.
