Aerial Survey of grey seals in the Wadden Sea of Lower Saxony and Hamburg-2020/2021
Kegelrobben-Kartierung im Niedersächsischen und Hamburgischen Wattenmeer per Flugzeug 2020-2021
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Dr. Abbo van Neer
Duration: Novemer 2020 until September 2021
Funding: Nationalparkverwaltung "Nieders. Wattenmeer"" Wilhelmshaven", 38.752 EUR
Project Details:
The aim of the project is a survey of the local grey seal population in the entire Lower Saxony and Hamburg Wadden Sea during the birthing season (November-December) and at the time of the fur change (March-April).
On five trilaterally coordinated dates (three during the birthing season; two during the fur-change period), airborne surveys will be conducted with a single-engine aircraft. During the aerial surveys of the tidal flats, a high-resolution SLR camera will be used to photograph the haul-outs. In order to determine the number of young born as well as the total population, the photos taken are subsequently analyzed on the computer.

Domestic animals as potential vectors for SARS-CoV-2 transmission ANI-CoV)
Haustiere als potenzielle Vektoren für die Übertragung von SARS-CoV-2 (ANI-CoV)
Project Investigators: W. Baumgärtner
Duration: June 2020 until Novemer 2021
Funding: BMBF, 101.062 EUR
Project Details:
In dem Projekt ANI-CoV soll untersucht werden, welche Haus- und Nutztierarten für das SARS-CoV-2 empfänglich sind und möglicherweise dieses Virus auf den Menschen oder weitere Tierspezies übertragen können. Während sich bereits erste Studien mit der Suche nach dem Reservoirwirt und der Identifizierung von möglichen Überträgern im Rahmen des Ausbruchs in Wuhan, China befassen, fehlen bisher Informationen darüber, ob weitere Tierspezies SARS-CoV-2 verbreiten können. Dieses Projekt befasst sich daher mit der Fragestellung, ob Haustiere wie Katzen, Hunde und Frettchen und Nutztiere, insbesondere Rinder und Schweine, potentielle Überträgerwirte darstellen. Die Relevanz den Fokus auf Haus- und Nutztiere zu legen, ist durch den regelmäßigen und engen Kontakt des Menschen mit diesen Tieren zu erklären. Für die Untersuchungen werden verschiedene Zellkultursysteme (Lungen-Präzisionsschnitte, Explantate der Nasenschleimhaut, Air-liquid-interface Kulturen) hergestellt und infiziert. Neben der Empfänglichkeit einzelner Tierspezies soll auch der Einfluss der SARS-CoV-2 Infektion auf die Morphologie und Funktion der infizierten Zellen untersucht werden. Ein weiterer Fokus soll hierbei auf SARS-CoV-2 induzierter und veränderter Zilienmorphologie und -Aktivität gelegt werden.

Comparison of different radiologic scores and echocardiography to evaluate the size of heart and left ventricle in dogs
Vergleich verschiedener radiologischer Scores und der Echokardiographie zur Beurteilung der Größe des Herzens und des linken Vorhofs beim Hund
Project Investigators: Dr. J.-P. Bach; Prof. I. Nolte
Duration: May 2020 until March 2021
Project Details:
Die Frage einer möglichen Vergrößerung von linkem Vorhof und linker Hauptkammer spielt eine entscheidende Rolle in der Therapieentscheidung und der Prognose bei verschiedenen Herzerkrankungen des Hundes. Als Goldstandard zur strukturellen Beurteilung des Herzens gilt hier regelmäßig die Echokardiographie. Da diese Technik Spezialisten vorbehalten ist, besteht ein großes Interesse an geeigneten radiologischen Messparametern, um eine Beurteilung bei Patienten, bei denen eine Echokardiographie nicht möglich ist, vornehmen zu können. In dieser Studie sollen verschiedene Röntgenscores auf ihre Eignung zur Beurteilung der Herzgröße beim Hund überprüft werden.

Acoustic harbour porpoise monitoring 2021
Akustisches Monitoring von Schweinswalen 2021
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Dr. Johannes Baltzer
Duration: Novemer 2020 until October 2021
Funding: Landesbetrieb f. Küstenschutz, Nationalpark u. Meeresschutz Schleswig-Holstein, Tönning, 51.769 EUR
Project Details:
Harbour porpoises are representatives of marine mammal top predators in the North Sea and Wadden Sea. With the amendment of the National Park Act in 1999, part of the national park was explicitly dedicated to the protection of harbour porpoises, since a high density of mother-calf groups was found in this area. As part of the reorganization of the Federal-State Marine Programme (BLMP), a programme for the joint monitoring of marine mammals was agreed in January 2011, which meets the requirements of monitoring in accordance with the relevant European directives and international conventions. The Schleswig-Holstein National Park Administration (NPV) in the Schleswig-Holstein State Agency for Coastal Protection, National Park and Marine Conservation (LKN) is responsible for organizing, implementing and financing the acoustic monitoring of harbour porpoises in this programme. The acoustic surveys for the NPV are carried out by the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) as part of the joint marine mammal monitoring within the BLMP. For this purpose, measuring stations are operated at four defined locations in the Schleswig-Holstein Wadden Sea (Lister Tief, Meldorfer Bucht, Rochelsteert and Westerland). Since this year another measuring station was deployed in the Elbe estuary. The measuring stations are equipped with click detectors (C-PODs), which record the echolocation activity of harbor porpoises. The C-PODs are serviced and data downloaded at regular intervals. The obtained data is evaluated against the background of the optimization of the acoustic monitoring as well as necessary extensions for a permanent operation of the measuring stations. The data from this long-term study will provide information on the possible pattern and tidal dependency of harbor porpoise detections throughout the day and over the course of a year.
Results:

The data analysis showed that harbor porpoises have been detected at all monitoring positions over the study period to date. However, spatial (between stations) and temporal differences (individual years, over the course of a year, over the course of a day) in detection rates were documented. At the station Lister Tief (LT), on the eastern side of Sylt, the lowest detection rates were recorded. The station Westerland (WL), west of Sylt in the whale sanctuary, has the highest detection rates (maximum per day) over the study period. The station Meldorfer Bucht (MB), which is located in the immediate vicinity of Büsum harbour, also showed very high detection rates, with an increasing trend in the summer months. The modelling of the individual stations could clearly show that there is a strong seasonality in the harbor porpoise detections. All stations show a maximum in detections in spring, in the period from mid-March to mid-April. This period is just before the phase of the highest birth rate, which lasts from mid-June to end of July. During this period, increased detections were only detected at station MB. Approximately two months after breeding begins the mating season of harbour porpoises in the North Sea. Within this period, an increased detection was observed at Rochelsteert station (RS) in contrast to all other stations. This could be an indication that the area around the station is used for mating. The calves are suckled for about 10 months, but start feeding independently on solid food, in the form of small shrimp-like crabs (Euphausiidae, e.g., North Sea shrimp), with the age of approximately five months. During this stage, an increase in detection rates was documented at Station LT. It is conceivable that juvenile harbour porpoises visit shallow water areas, such as the area at station LT, to forage on benthic first solid food.

Time of day had little effect on detection rates over the entire study period. However, a pattern in diurnal rhythms with more frequent detections in the morning hours was observed at Station LT. A similar pattern was also evident at station RS, with slightly higher detections throughout the day.

The tidal effect is more pronounced than diurnal patterns and could be observed at high tide or in the phases between high and low tide. Station LT shows increased detection rates just before low tide and a minimum during high tide. When comparing stations WL and RS with MB, an opposite effect is observed. Station MB shows a minimum in detection rates shortly after high tide, wheras a maximum during high tide was present at stations WL and RS.

Harbour porpoises were also detected at the measuring station in the Elbe estuary. The data does not yet allow for modelling over the entire year, as the station was just deployed in summer. However, the tidal effect with a maximum of harbour porpoise detections at high tide and lower detections at low tide has already been documented.

The Wadden Sea monitoring has so far generated robust and continuous long-term data sets up to ten years of harbour porpoise click activity. With these unique data sets, it is possible to generate models that provide information on harbour porpoise presence in the Wadden Sea and the effect of possible environmental parameters. The increase of the data base over the years has shown that the models provide an increasingly clear picture of the effect of abiotic factors on harbour porpoises. The assessments of harbour porpoise presence required by international agreements (MSFD and trilateral agreements) can currently only be carried out on a temporal scale using the acoustic data generated within the project with click detectors. In order to further expand the data base and thus improve the quality for assessment, it is necessary to continue the Wadden Sea monitoring every year.
