2014-5-29 · Halpern et al., 2008). One of the key factors governing the recovery of coral communities is the maintenance of settlement space and the reduction of algal overgrowth through the actions of herbivores (Mumby, 2006; Hughes et al., 2007; Birrell et al., 2008; Burkepile and Hay, 2010). The dominant coral reef fish herbivores include foragers et al., 2009; Deter et al., 2012), and the interplay between the number of points per image and the number of images has been well studied (e.g. Brown et al., 2004). However, attributes of bio-logical organisms, such as size, abundance and spatial pattern may also affect this trade-off, but have not been considered. Further,
