This study indicates that rate of vocalisation
may provide a gauge to assess levels of disturbance to penguins at tourism sites.
Says Howard, Eoe1/4EoWe use a specially designed microphone (called a hydrophone) which is lowered into the sea from our boat on a long cable and digitally records the Eoe1/4Y[pounds sterling]songEoe1/4ao of humpback whales as well as the vocalisations
of other whales and dolphins.
The researchers believe that the speed with which the brain 'tags' these vocalisations
and the preference given to them compared to language, is due to the potentially crucial role that decoding vocal sounds has played in human survival.
She said the type of communication the researchers observed in the wild bonobos could represent an important evolutionary transition from vocalisations
that are tied to specific contexts or emotional states towards human vocalisations
They found that the babies were already able to make vocalisations
at week 32.
The authors note that, given that 30% of households are thought to have televisions on all of the time, the results raise a question about how many opportunities of child and parent vocalisations
are being displaced.
The acoustic structure of particular monkey vocalisations
may be adaptively designed to attract young infants.
Grace a des enregistrements accompagnes d'observations sur le terrain, nous avons trouve une correlation entre le nombre de vocalisations
entendues et le nombre de narvals observes.
Tourette's syndrome (TS) is an inherited neurobehavioural disorder characterised by sudden, involuntary, repetitive muscle movements (motor tics) and vocalisations
