Population genetic studies of two tropical lowland rain forest tree species in the forest fragments of Singapore using AFLP. ScholarBank@NUS Repository.||Abstract:||To study the genetic effects of forest fragmentation in Singapore, two native species of lowland primary rain forest subcanopy trees, Calophyllum ferrugineum Ridley var. ferrugineum (Clusiaceae or Guttiferae) and Streblus elongatus (Miq.) Corner (Moraceae), were selected primarily because of their abundance in the three remaining primary forests on Singapore Island. Streblus elongatus was also collected in tall secondary forest on Singapore Island, Pulau Tekong, Pulau Ubin, Sentosa and St.Johna??s Island.This studya??s aims were 1) to determine the genetic differences between populations, 2) to determine the genetic differences within populations, in particular between the adults separated into two size classes (trunk circumference at breast height a?Y 100 cm and = 40a??60 cm) and juveniles (height a?? 50 cm) and 3) to determine if there is a correlation between genetic and geographical distances for adults and juveniles, respectively. The amplified fragment length polymorphism technique was utilised to generate genetic data.||URI:||http://scholarbank.nus.edu.sg/handle/10635/23166|
