A balance device for the analysis of behavioural patterns of the mouse

A device for analysing mouse behaviour which is based on recording the movements of the animal in a balance test cage has been developed. The amplitude patterns provoked by the movements of the animal correlate with behavioural patterns. The system not only allows differentiation between five behavioural categories: resting, grooming, eating, locomotion and climbing – […]

Why Do Dolphins Jump? Interpreting the Behavioural Repertoire of Bottlenose Dolphins (Tursiops sp.) in Doubtful Sound, New Zealand

Only a limited number of studies have tried to determine the purpose of surface behavioural events performed by dolphins. To date only one study has attempted to aggregate the behavioural events observed in a population in contextual groups using co-occurrence as the grouping factor. In the present study, I tried to characterise the behavioural repertoire […]

Seasonal variation in the length of the daily activity period in buffy-headed marmosets (Callithrix flaviceps): An important consideration for the analysis of foraging strategies in observational field studies of primates

Activity budgets are widely used in primate behavioral studies for the analysis of ecological strategies. In some cases, there is considerable seasonal variation in the length of the daily activity period. Here, activity budgets from two field studies of Callithrix flaviceps were compiled first by the traditional approach (proportion of scan sample records) and then […]
