Aquatic Mammals (2007)
Circulating cortisol levels are accepted as a sensitive indicator of acute stress in marine mammals, particularly in relation with capture and handling. The present study provides the first long-term monitoring…
Population status, threats and conservation of the Yangtze finless porpoise
Wang, Ding
Chinese Science Bulletin (2009)
The Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) is currently limited to the middle and lower reaches of the Yangtze River from Yichang to Shanghai, China, and the adjoining Poyang and…
Prey capture by harbor porpoises (Phocoena phocoena): A comparison between echolocators in the field and in captivity
Miller, L.A.
The Journal of the Marine Acoustics Society of Japan (2010)
The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…
Variation in sexual behaviors in a group of captive male Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis): Motivated by physiological changes?

Theriogenology (2010)
Most male mammals in temperate regions demonstrate seasonal sexual behaviors that coincide with seasonal variations in gonadal activities and androgen hormones. The Yangtze finless porpoise is a temperate freshwater cetacean…

In December 2005 construction work was started to replace a harbor wall in Kerteminde harbor, Denmark. A total of 175 wooden piles were piled into the ground at the waters…
Studying the biosonar of bats and porpoises using multi receiver arrays
Koblitz, Jens C.
Doctoral Thesis - Eberhard Karls Universität Tübingen (2014)
Echolocation, the main sensory modality of odontocetes and microbats, has mostly been studied using single receivers. Such a recording setup is sufficient to study signal parameters like pulse interval, inter…
Fatal disseminated Toxoplasma gondii infection in a captive harbour porpoise (Phocoena phocoena)
Herder, V.; van de Velde, N.; Højer Kristensen, J.; van Elk, C.; Peters, M.; Kilwinski, J.; Schares, G.; Siebert, U.; Wohlsein, P.
Journal of Comparative Pathology (2015)
A 7-year-old female harbour porpoise (Phocoena phocoena), born and held in captivity, suffered from reduced consciousness, imprecise and circling swimming movements and long phases of immobility over a period of…
Conditioned hearing sensitivity change in the harbor porpoise (Phocoena phocoena)
Nachtigall, Paul E.; Supin, Alexander Ya.; Pacini, Aude F.; Kastelein, Ronald A.
The Journal of the Acoustical Society of America (2016)
Hearing sensitivity, during trials in which a warning sound preceding a loud sound, was investigated in two harbor porpoises (Phocoena phocoena). Sensitivity was measured using pip-train test stimuli and auditory…
Reversible bending of the dorsal fins of harbor porpoises (Phocoena phocoena) and a striped dolphin (Stenella coeruleoalba) in captivity
Kastelein, Ronald A.; Triesscheijn, Rob J. V.; Jennings, Nancy
Aquatic Mammals (2016)
The dorsal fin of odontocetes has, among other roles, hydrodynamic and thermoregulatory functions. In captivity, the dorsal fin sometimes bends laterally. Bending of the dorsal fin was described in 13…

CIRVA
(2016)
EXTINCTION IS IMMINENT CIRVA reviewed the 2015 population survey results, which showed that only about 60 vaquitas remained at the beginning of the emergency 2-year partial gillnet ban. CIRVA also…
