Seasonal dynamics of occurrence and group size of three species of cetaceans (Delphinidae and Phocoenidae) on the southwestern coast of the Black Sea

Scientia Marina, 2020
The spatial and temporal occurrence of cetaceans in the Black Sea and particularly along its southwestern coastline is poorly studied. Based on a total of 609 encounters, we present the analysis of monthly dynamics of (1) the numbers of cetacean ...

Age and lunar cycle predict harbor porpoise bycatch in the south-western Baltic Sea [PDF]

PeerJ, 2021
The harbor porpoise, Phocoena phocoena, is the only cetacean regularly occurring in the Baltic Sea. During the last decades, several anthropogenic activities have affected porpoises in the Baltic region.

Sightings of Cetaceans in the waters of Yuzhny Sea Port (Hryhorivsky Estuary, Black Sea) in 2015–2016 [PDF]

Праці Теріологічної школи, 2016
The use of transformed coastal ecosystems by the Black Sea cetaceans is an important, but little studied issue. In 2015–2016, coastal visual observations of cetaceans were conducted in the waters of Yuzhny Sea Port.

Testicular morphology and spermatogenesis in harbour porpoises (Phocoena phocoena) [PDF]

Theriogenology, 2019
Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the present study was to report changes in the histological appearance of the testicular morphology of neonatal and juvenile harbour porpoises during ...

First report of infestation by a parasitic copepod (Pennella balaenopterae) in a harbour porpoise (Phocoena phocoena) from the Aegean Sea: a case report

Veterinární Medicína, 2014
An adult, female harbour porpoise (Phocoena phocoena relicta) was found stranded on the southern Aegean Sea coast of Turkey. Thirteen holes made by copepods were observed on the lateral sides of the porpoise.

An evolutionary divergent pestivirus lacking the Npro gene systemically infects a whale species

Emerging Microbes and Infections, 2019
Pestiviruses typically infect members of the order Artiodactyla, including ruminants and pigs, although putative rat and bat pestiviruses have also been described. In the present study, we identified and characterized an evolutionary divergent pestivirus

Return of the Salish Sea Harbor Porpoise, Phocoena phocoena: Knowledge Gaps, Current Research, and What We Need to Do to Protect Their Future

Frontiers in Marine Science, 2021
The harbor porpoise (Phocoena phocoena) is one of the most abundant coastal cetacean species in the Northern Hemisphere with differential levels of regional knowledge.

Bottlenose dolphins (Tursiops truncatus) aggressive behavior towards other cetacean species in the western Mediterranean

Scientific Reports, 2021
Aggressive behavior of bottlenose dolphins (Tursiops truncatus) towards conspecifics is widely described, but they have also often been reported attacking and killing harbour porpoises (Phocoena phocoena) around the world. However, very few reports exist

Spatial orientation in echolocating harbour porpoises (Phocoena phocoena) [PDF]

Journal of Experimental Biology, 2005
SUMMARY Studies concerning the echolocation behaviour of odontocetes focus mainly on target detection and discrimination, either in stationary animals or in animals approaching a specific target. We present the first data on the use of echolocation for spatial orientation or navigation.
