|Title:||Tree seedling growth and survival in a Malaysian rain forest||Authors:||Turner, I.M.||Issue Date:||1990||Citation:||Turner, I.M. (1990). Tree seedling growth and survival in a Malaysian rain forest. Biotropica 22 (2) : 146-154. ScholarBank@NUS Repository.||Abstract:||Growth and survival of tree seedlings were observed in lowland, evergreen, tropical rain forest in Pantai Aceh Forest Reserve, Penang, Peninsular Malaysia. Four natural gaps and two closed-canopy sites were used. At the start of observations 1287 seedlings of 116 species were tagged in 120 1-m2 plots. Over 16 months 251 (19.5%) seedlings died. Mortality was inversely correlated with seedling height. Potential direct radiation had no affect on seedling mortality. For the 5 common species mortalities were: Shorea multiflora 6.2%, Hopea pedicellata 6.8%, Shorea curtisii 13.4%, Hopea beccariana 14.1%, and Gluta curtisii 22.7%. Mortality of recruits from seed was: S. multiflora 19.0%, S. curtisii 29.1% and G. curtisii 29.5%. The seedlings grew very little over the 16 months. Height growth was greater in gap sites. There was a significant relationship between direct site factor and plot maximum height growth but its predictive value was poor. Gluta curtisii was the only species to show a significant relationship between direct site factor and height growth. Shorea multiflora and G. curtisii showed a significantly greater rate of height growth in the plots with above-median direct site factor compared to plots with below-median values. Shorea multiflora is a very shade tolerant species. -from Author||Source Title:||Biotropica||URI:||http://scholarbank.nus.edu.sg/handle/10635/99780||ISSN:||00063606|
