Abstract
M. calabura is a fast growing tree of disturbed lowland neotropical forests that has been introduced as an ornamental and fruit tree in many Old World countries. It is now widespread and naturalized in Southeast Asia, Australia, and in islands of the Pacific Ocean, in part due to its ability to disperse by bats and birds. It is often regarded as an environmental weed, but has not yet become a severe widespread problem (Werren, 2001; Randall, 2012). Listed as invasive in Puerto Rico (Haysom and Murphy, 2003; Rojas-Sandoval and Acevedo-Rodríguez, 2015), Singapore (Nghiem et al., 2015), Papua New Guinea (Orapa, 2006), Republic of Palau (Space et al., 2009), Nauru (Meyer, 2000) and the Federated States of Micronesia (Haysom and Murphy, 2003). Listed as potentially invasive in Guam and the Northern Mariana Islands (Meyer, 2000).
