Survival and growth of recruit-sized ramets of Sargassum polycystum growing inside or outside Sargassum beds (crowded and isolated conditions, respectively) in protected and non-protected areas (MPA and non-MPA, respectively) in two villages in Fiji.

Growth was obtained using the initial height measurement from each ramet and subtracting it from its final height, meaning the ramets that died were recorded as negative change. An average final height was calculated from two sub-samples (the two MPA and two non-MPA ramets) on each tile after 3 months of experiment. Survival was the average number of days survived by the two MPA ramets and by the two non-MPA ramets in each tile Details in Dell et al. 2016 Plos One.
