The first assessment of cetacean density and abundance by linear transect survey was conducted in 2016 and 2017 in the shallowest coastal area of the Ukrainian sector of the north-western…


The frequency of solitary behaviours in captive odontocetes is modulated by environmental and social factors

Serres, Agathe; Hao, Yujiang; Wang, Ding
International Journal of Comparative Psychology (2019)

The number of welfare-oriented studies is increasing in animals under human care, including odontocetes. However, validated welfare indicators are lacking for captive odontocetes. We studied the effect of several conditions…


Agonistic interactions and dominance relationships in three groups of captive odontocetes: Method of assessment and inter-species/group comparison

Social group dynamics are known to impact odontocetes’ health and welfare in captivity. Social dominance and agonistic interactions that occur to establish and maintain these relationships might express themselves differently…


Modeling of the near to far acoustic fields of an echolocating bottlenose dolphin and harbor porpoise

Wei, Chong; Au, Whitlow W. L.; Ketten, Darlene R.
The Journal of the Acoustical Society of America (2020)

Echolocation signals emitted by odontocetes can be roughly classified into three broad categories: broadband echolocation signals, narrowband high-frequency echolocation signals, and frequency modulated clicks. Previous measurements of broadband echolocation signal…
