“…[32], [21]). No significant differences have been found in the rate or depth of burial between seeds or seed mimics [33] and seeds mimics have the great advantage of not being removed by seed predators [25]. In each experimental dung pile, we placed seed mimics of three sizes: 50 small seeds (3.5-mm diameter), 20 medium seeds (8.6-mm diameter) and 10 large seeds (15.5-mm diameter).…”

“…Within this grid, plots were created by burying nylon netting 10 cm into the forest floor in a 50 3 50 cm square ( Fig. Previous investigations indicate that there are no differences in removal rate or burial depths between seed mimics and real seeds (Koike et al 2012). Each plot contained a non-baited pitfall trap (13.5 cm width, 9 cm depth), buried flush with the ground surface and filled with salt and water.…”

“…Previous investigations have demonstrated that burial by dung beetles is a mechanism for seed predator escape (e.g., Estrada andCoates-Estrada 1991, Feer 1999), but can also lead to mortality through placement of individual seeds within the soil in unsuitable locations for germination and establishment (Estrada and Coates-Estrada 1991, Shep-herd and Chapman 1998, Andresen 1999, Andresen and Levey 2004, Koike et al 2012.

“…This can benefit seeds by placing them in a more suitable microsite for germination [27,28], avoidance of density-dependent competition [29] and through escape from predation [27,30]. However, if seeds are placed too deep, burial by beetles can result in seed mortality [27,30,31]; suggesting there exists a species-specific optimal seed burial depth.…”
