Abstract
Predation on propagules ofRhizophora mangle was compared in forests where this species is non-indigenous (Hawai’i, USA) and where it is native (American Samoa). Tree density and basal area of the non-indigenous stand were intermediate when compared to natural stands in other places whereRhizophora is common. Propagules were tethered on the forest floor at both sites for 14 days, predation was recorded, and survival rates of both attacked and control individuals were determined by placing them in a mist room. Mortality was significantly greater in American Samoa (x=25%) than in Hawai’i x=8%). The lower effectiveness of the non-indigenous predators in Hawai’i may help explain the unusually high rate at whichR. mangle propagules become established there.
