“…This is allowed because when a clonal plant spreads, the connections linking the old established individual to the new recruited ramets may enhance temporally their maintenance, growth and/or survival under unsuitable environmental conditions (Hartnett & Bazzaz 1983, Cook 1985, Peltzer 2002. This integration may be especially beneficial in environments where resources are scarce and/or patchily distributed both in time and space, such as sand dunes or rocky ground (Pitelka & Ashmun 1985, Alpert & Mooney 1986, since resources can be re-distributed within the clone from sites of acquisition to sites where resources are scarce (Hutchings 1988, Hutchings & Wijesinghe 1997 (Sampaio et al 2002). On the other hand, the large A. nudicaulis ramet system creates settlement opportunities to other less-stress resistant plant species (Sampaio et al 2005), highlighting the importance of clonal integration even to such ecosystem processes (see Scarano 2002).…”

“…Esta planta é classificada como epífita facultativa e heliófita (Anacleto et al, 2008) e produz um ou dois novos rametes por ano após a floração, interdistantes 10 cm, sendo caracterizada como semelpara, apresentando um único evento de reprodução sexuada (Sampaio et al, 2002).…”
