Association networks reveal social organization in the sleepy lizard
We investigated the social organization of the Australian sleepy lizard, Tiliqua rugosa, by describing the social network of a local population. We attached activity meters and GPS recorders to 21 neighbouring lizards in a semiarid site in South Australia, and monitored their location every 10 min over 3 months (September-December 2007). From over 5000 sets of […]
Social network analysis of the behavioural interactions that influence the development of fin damage in Atlantic salmon parr (Salmo salar) held at different stocking densities
Social network analysis of behavioural interactions was used to quantify the effect of high (HD, 30 kg m-3) and low (LD, 8 kg m-3) stocking densities on the frequency and severity of fin damage in Atlantic salmon. Dorsal fin damage (erosion, splits, fin index) was significantly higher in HD compared to LD groups with higher amounts of dorsal fin […]
Investigating the influence of predictable and unpredictable feed delivery schedules upon the behaviour and welfare of Atlantic salmon parr (Salmo salar) using social network analysis and fin damage
Social network analysis was utilised to quantify the effect of short-term predictable (PD) and unpredictable (UD) feed delivery schedules of 10 days on behavioural interactions and the frequency and severity of fin damage in Atlantic salmon. Fin damage was only observed on the dorsal fin and its frequency and severity was significantly higher in UD […]
