Fernandez-Betelu, Oihane; Graham, Isla M.; Malcher, Freya; Webster, Emily; Cheong, Sei-Him; Wang, Lian; Iorio-Merlo, Virginia; Robinson, Stephen; Thompson, Paul M.
Marine Pollution Bulletin (2024)

Many man-made marine structures (MMS) will have to be decommissioned in the coming decades. While studies on the impacts of construction of MMS on marine mammals exist, no research has…

Biological characteristics of pregnancy in captive Yangtze finless porpoises revealed by urinary metabolomics

Tang, Bin; Hao, Yujiang; Wang, Chaoqun; Deng, Zhengyu; Kou, Zhangbing; Zhou, Haojie; Zhang, Haobo; Fan, Fei; Wang, Kexiong; Wang, Ding
Biology of Reproduction (2024)

The Yangtze finless porpoises (Neophocaena asiaeorientalis a.) are an endemic and critically endangered species in China. Intensive captive breeding is essential for understanding the biology of critically endangered species, especially…

TDP-43 and Alzheimer’s disease pathology in the brain of a harbor porpoise exposed to the cyanobacterial toxin BMAA

Garamszegi, Susanna P.; Brzostowicki, Daniel J.; Coyne, Thomas M.; Vontell, Regina T.; Davis, David A.
Toxins (2024)

Cetaceans are well-regarded as sentinels for toxin exposure. Emerging studies suggest that cetaceans can also develop neuropathological changes associated with neurodegenerative disease. The occurrence of neuropathology makes cetaceans an ideal…

Using marine mammal necropsy data in animal health surveillance: The case of the harbor porpoise in the Southern North Sea

IJsseldijk, Lonneke L.; van den Broek, Jan; Kik, Marja J. L.; Leopold, Mardik F.; Bravo Rebolledo, Elisa; Gröne, Andrea; Heesterbeek, Hans
Frontiers in Marine Science (2024)

Rapid changes of marine ecosystems resulting from human activities and climate change, and the subsequent reported rise of infectious diseases in marine mammals, highlight the urgency for timely detection of…

Implications of porpoise echolocation and dive behaviour on passive acoustic monitoring

Macaulay, Jamie Donald John; Rojano-Doñate, Laia; Ladegaard, Michael; Tougaard, Jakob; Teilmann, Jonas; Marques, Tiago A.; Siebert, Ursula; Madsen, Peter Teglberg
The Journal of the Acoustical Society of America (2023)

Harbour porpoises are visually inconspicuous but highly soniferous echolocating marine predators that are regularly studied using passive acoustic monitoring (PAM). PAM can provide quality data on animal abundance, human impact,…

Genome-wide analysis of the harbour porpoise (Phocoena phocoena) indicates isolation-by-distance across the North Atlantic and potential local adaptation in adjacent waters

Autenrieth, Marijke; Havenstein, Katja; De Cahsan, Binia; Canitz, Julia; Benke, Harald; Roos, Anna; Pampoulie, Christophe; Sigurðsson, Guðjón Már; Siebert, Ursula; Olsen, Morten Tange; Biard, Vincent; Heide-Jørgensen, Mads Peter; Öztürk, Ayaka Amaha; Öztürk, Bayram; Lawson, John W.; Tiedemann, Ralph
Conservation Genetics (2023)

The harbour porpoise (Phocoena phocoena), a highly mobile cetacean species of the Northern Hemisphere, inhabits basins that vary broadly in salinity, temperature, and food availability; such variation can drive divergent…

Hardly seen, often heard: Acoustic presence of harbour porpoises (Phocoena phocoena) in one of the most urbanised estuaries in the world

Rekdahl, Melinda L.; Trabue, Sarah G.; King-Nolan, Carissa D.; Strindberg, Samantha; Rosenbaum, Howard C.
Frontiers in Marine Science (2023)

The New York-New Jersey (NY-NJ) Harbour Estuary and surrounding waters support the largest port along the U.S. East Coast, commercial and recreational fishing, and a burgeoning offshore wind energy industry.…

Wild harbour porpoises startle and flee at low received levels from acoustic harassment device

Elmegaard, Siri L.; Teilmann, Jonas; Rojano-Doñate, Laia; Brennecke, Dennis; Mikkelsen, Lonnie; Balle, Jeppe D.; Gosewinkel, Ulrich; Kyhn, Line A.; Tønnesen, Pernille; Wahlberg, Magnus; Ruser, Andreas; Siebert, Ursula; Madsen, Peter Teglberg
Scientific Reports (2023)

Acoustic Harassment Devices (AHD) are widely used to deter marine mammals from aquaculture depredation, and from pile driving operations that may otherwise cause hearing damage. However, little is known about…

Blood transcriptome analysis provides responsive changes in gene expression between ex situ and captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)

Cao, Z.; Yin, D.; Li, Z.; Yan, Y.; Zhang, P.; Zhang, S.; Lin, D.; Hua, Z.; Zhang, J.; Ying, C.; Zhang, H.; Xu, P.; Dong, G.; Liu, K.
Fishes (2023)

The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP) is an endangered species endemic to the Yangtze River in China, and it is the only freshwater whale in the genus Neophocaena.…
