Mice with reduced reelin expression or prenatal exposure to CPO exhibited subtle changes in ultrasound vocalization, open field behaviour, social interaction and repetitive behaviour.
The method involves assessment of behavioural indicators of pain (comfort, movement, appearance, behaviour, vocalization, feeding and wound touch) assigning a score of 0 3 for each category.
We expect that follow-up investigations of sequence variation at other loci, and studies on morphology, behaviour, vocalization and distributions (e.g., ref. [47]) will rapidly advance understanding of the diversity and diversification of the Neotropical avifauna.
The video footage was subsequently used to score any of the following listed behaviour: vocalization, barking, whining, panting, salivating, ears back, shaking of the body, urinating, defecating, tail between the legs, running away, hiding, seeking attention from the tester, lowering of the body posture and freezing.
Activities such as rumination, eating, drinking, grooming, vocalization, scratching, hierarchal behaviour and movements to keep flies away were recorded every 60 seconds.
This view is supported by behavioural studies comparing ultrasonic vocalizations and related behaviour of females and males.
The smooth-coated otter (Lutrogale perspicillata) of Asia may be its closest extant relative; similar behaviour, vocalizations, and skull morphology have been noted.
Using a place preference design, we show that these vocalizations elicited approach behaviour in females.
Bird vocalization and behavior are better understood than bat vocalization, he says.
Nearly as important in territorial behaviour as vocalization is the white throat patch.
