“…In many areas, 100% of seed production is lost to predation (Jansen 1971). The relatively few studies to date suggest that predation on seagrass seeds may be an important process governing seed survival and ultimately, seedling establishment (Wassenberg & Hill 1987, Wigand & Churchill 1988, Wassenberg 1990, Fishman & Orth 1996, Holbrook et al 2000. In particular, one of the more comprehensive studies on seed predation to date on surfgrass, Phyllospadix torreyi, (Holbrook et al 2000) found predation occurring in both the predispersal (7 to 15%) and dispersal (> 50%) phases, and to be temporally variable (10 to 50%).…”

“…For example, Wassenberg & Hill (1987), Wassenberg (1990) and O'Brien (1994) found seeds of Zostera capricorni to be an important part of the diet of the juvenile brown tiger prawn Penaeus esculentus during periods of seed production. Wigand & Churchill (1988) found that a variety of crustaceans fed on Z. marina seeds in the laboratory when alternative foods were not available. Fishman & Orth (1996) found the blue crab Callinectes sapidus to be an important seed predator of Z.…”

“…However, in 2004 and2005, when the number of seeds produced was 10 to 20 times higher than in 2003, about 5 to 7% of the produced seeds remained in the seed bank. Large numbers of seeds produced at the site probably dispersed to unvege-tated areas and/or were consumed by seed predators (Wigand & Churchill 1988, Fishman & Orth 1996, Nakaoka 2002. Only a small portion of the eelgrass seeds in seed banks usually develops successfully into adult shoots (Harrison 1993, Olsen 1999.…”

“…Eelgrass seed production has been found to be highly variable, ranging from 200 to about 80 000 seeds m -2 (Hootsmans et al 1987, Keddy 1987, Harrison 1993, Fishman & Orth 1996. A large proportion of seagrass seeds may be lost to predation, disease, and transport to unsuitable sites (Wigand & Churchill 1988, Fishman & Orth 1996, Inglis 2000, Nakaoka 2002, causing discrepancies between seed production and seedling abundance.…”
