We evaluated the extent to which manipulation of early olfactory environment can influence social behaviours in the South American Hystricognath rodent Octodon degus. The early olfactory environment of newborn degus was manipulated by scenting all litter members with eucalyptol during the first month of life. The social behaviour of sexually mature animals (5-7 months old) towards conspecifics ...

There is a need for reliable and efficient methods monitoring the activity social behaviour in cows, order to optimise management modern dairy farms. This research presents an embedded system that could track individual cows using Ultra-wideband technology. At same time, interactions between individuals around feeding area were analysed with computer vision module. Detections of cows’ negative ...

In birds, the link between parental care behaviour and prolactin release during incubation persists after hatching in altricial birds, but has never been precisely studied during the whole rearing period in precocial species, such as ducks. The present study aims to understand how changes in parental care after hatching are related to circulating prolactin levels in mallard hens rearing ducklin...

In young black-headed gulls (Larus ridibundus), exposure to testosterone increases the sensitivity of agonistic behaviour to a subsequent exposure to this hormone. The aim of this paper is twofold: to analyze whether social experience, gained during testosterone exposure, mediates this increase in hormonal sensitivity (priming), and whether this in turn is mediated by an increase in central aro...

Behavioral observation, economic, and genealogical data collected in a rural Trinidadian village indicate: (1) males courting the same females have higher rates of agonistic interactions (e.g., arguing, fighting) with each other than they do with other mates; (2) females courting the same males do not have higher rates of agonistic interactions with each other than they do with other females; (...

When social animals engage in inter-group contests, the outcome is determined by group sizes and individual masses, which together determine group resource-holding potential ('group RHP'). Individuals that perceive themselves as being in a group with high RHP may receive a motivational increase and increase their aggression levels. Alternatively, individuals in lower RHP groups may increase the...

In male golden hamsters, exposure to social stress during puberty alters aggressive behavior. Interestingly, agonistic behavior undergoes two major transitions during puberty: a decline in attack frequency and a shift from play fighting to adult-like aggression. Based on previous observations, we developed an approach for characterizing offensive responses as play fighting or adult-like. The pr...

Many animals make sounds for various reasons, mostly mating and agonistic behaviour, but also more complex social communication. These are used mapping monitoring many animal groups species (e.g. birds, bats, whales, grasshoppers, crickets) monitoring. Although Glirids known to use communication, our knowledge vocalisations have only been map the Edible Dormouse. We checked possibility of detec...
