Test and implementation of specific management measures to create a seal exclusion zone in the swimming area on Helgoland
Erprobung und Implementierung von Managementmaßnahmen zur bedarfsgerechten Schaffung einer Robben-Exklusionszone im Schwimmbereich der Helgoländer Düne
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Dr. Abbo van Neer
Duration: May 2020 until July 2022
Funding: Ministerium für Energiewende, Landwirtschaft, Umwelt, Natur und Digitalisierung, 225.774 EUR
Project Details:
The population of the native grey seals (Halichoerus grypus) developed well after their protection and subsequent recolonisation of the Wadden Sea. The positive trend of the population poses a challenge from the management perspective. There is an increasing requirement of suitable habitat, which is commonly associated with enhanced conflict potential. A special kind of conflict exists on the Heligoland Dune, where the largest grey seal colony occurs in German waters. Individual animals habituated to human presence due to spatial density and the continuous close contact between humans and animals and therefore do not display the expected escape reflex anymore. This involves an increased risk potential for swimmers, especially in the water. This study aims to test specific management measures in order to create a swimming area safe for people and to implement them officially if successful. On that account, an acoustic method shall be tested, which has not been used for that purpose yet and is based on the so called startle reflex. In contrast to conventional acoustic devices scaring off seals unspecifically, a very specific signal will be used, which has got no extensive negative effects on target and also non-target species in theory. The study investigates if the application of this system has got the desired efficiency and causes no evident negative effects in this special context.
Results:

Within the framework of the project work already carried out, it has not yet been possible to achieve the targeted goals, as unexpected problems have arisen during data collection in the field. Considering the importance of this system for the community of Helgoland, as well as for the acceptance of grey seals by the inhabitants and guests of Helgoland, it would be important to complete this started experiment. Through a desired project extension, an objectively evaluable data basis should be created, wherewith the acoustic deterrence system can be evaluated.

The range of responsibilities of consultants will be defined, recommendations shall be given how responsible consultation can be put into practice. Concepts and material for further training courses will be developed, which on one hand clarify the responsibility of consultants and on the other hand also convey the aspects of animal ethics in counselling.

Behavioural traits and personality in the strawberry poison frog, Oophaga pumilio
Verhaltensmerkmale und Persönlichkeiten beim Erdbeerfrosch, Oophaga pumilio
Project Investigators: Ricardo Cossio; Prof. Dr. Heike Pröhl; Dr. Ariel Rodríguez
Duration: February 2019 until December 2022
Funding: Smithsonian Tropical Research Institute, Panama Secretaria Nacional de Ciencia y Tecnologia, Panama, 37.170 EUR
Project Details:
Variation in biological traits is universal in natural populations and has significant evolutionary and ecological consequences. Behavioral traits or combinations of traits are important as they may affect the survival and reproductive success of individuals. Studies have shown that animal personalities and behavioral traits covary with ecological conditions, dependent on the state of the individual, and can be maintained by frequency dependent selection. Animal personalities have been often been classified along five behavioral axes, namely, shyness-boldness, exploration-avoidance, activity, aggressiveness, and sociability. Some studies have shown that amphibians display personality and behavioral traits. However, implications of animal personality in ecological context remain largely unexplored in amphibians. Neotropical poison frogs are toxic and diurnal amphibians with highly evolved parental care and territorial behavior. In this study, we will investigate behavioral traits and personality of the strawberry poison frog within and between populations that differ in their anti-predator strategy (level of aposematism). Therefore, we will examine variations in exploratory, risk-taking and aggressive behavior by running standardized laboratory-based trials on wild-caught adult O. pumilio. Each frog will be tested in three behavioral trials, with the following sequence: exploration, risk-taking and aggressiveness. Within a population, we expect individuals present variations in behavioral traits and personality, and that behavioral traits might be correlated (syndrome). Among populations we expect more aposematic frogs (brighter coloration, higher toxicity) to be more explorative, bold and aggressive than less aposematic frogs.

Comparison of different Exercise Tests for the application in dogs
Vergleich verschiedener Belastungstests zum Einsatz beim Hund
Project Investigators: Dr. Jan-Peter Bach; Prof. Dr. I. Nolte; Dr. Lisa Harder; Rebekka Mach
Duration: May 2019 until April 2022
Project Details:
In der Vergangenheit sind zahlreiche Belastungstests beim Hund zum Einsatz gekommen. Hierbei handelt es sich meist um Adaptionen von Tests, die beim Menschen eingesetzt werden. Unter anderem wird in diversen Studien der 6-Minute-Walk-Test verwendet. Bei diesem Test wird die Strecke gemessen, die ein Patient im Rahmen von 6 Minuten zurücklegen kann. In einem Forschungsprojekt soll nun die Aussagekraft und Zuverlässigkeit dieses Tests mit der eines standardisierten, laufbandgestützten Belastungstests verglichen werden.

KoMARe II: Entwicklung betriebs- und verfahrenstechnischer Lösungen für eine nachhaltige, Stickstoff-effiziente und tiergerechte Indoor-Garnelenproduktion auf Basis der Biofloc Technologie (BFT)
Project Investigators: Steinhagen, Dieter; Jung-Schroers, Verena
Duration: August 2019 until March 2022
Funding: Deutsche Bundesstiftung Umwelt, 98.149 EUR
Project Details:
Die Aufzucht von aquatischen Organismen zur Gewinnung von Lebensmitteln in Kreislaufanlagen in Gebäuden an Land ist aus Gründen des Umweltschutzes (Vermeiden von Nährstoff-Eintrag in Gewässer) und Sicherstellung der Wasserversorgung der Aquakultur angesichts eines stark schwankenden Wasserangebots durch den Klimawandel dringend geboten. Allerdings ist die Technologie hinsichtlich Nachhaltigkeit und Tierwohl noch nicht ausgereift und daher verbesserungswürdig. Die relativ junge und in Europa noch wenig realisierte Biofloc-Technologie (BFT) bietet nach dem derzeitigen internationalen Stand der Kenntnis für die Zielstellung einer nachhaltigen Aquakultur ein bedeutendes Potenzial, das es zu entwickeln gilt. Das Potenzial von BFT-Systemen zur Umweltentlastung bei der Aufzucht von tropischen Riesengarnelen (Litopenaeus vannamei)besteht im Vergleich zu herkömmlichen Kreislaufanlagen darin, dass aus Detritus, Bakterienkolonien und kleinen Wirbellosen bestehende Bioflocken von Garnelen als Nahrung aufgenommen werden können und so zu einer Re-zirkulation von Nährstoffen (Stickstoff, Phosphor, organische Reststoffe), verbunden mit einem reduzierten Ressourceneinsatz (Wasser, Futtermittel), zu einer geringeren Freisetzung von eutrophierenden Stickstoff- und Phosphorverbindungen und letztlich zu einer erhöhten Biosicherheit und Produktivität bei einem niedrigeren spezifischen Energieverbrauch führen. Darüber hinaus kann die Verwendung von Bioflocken, die in ihrer Zusammensetzung der natürlichen Nahrung von Garnelen entsprechen, zu einer Verbesserung des Tierwohls durch verbesserte Fütterung führen.
