Abstract

Johannesteijmannia altifrons is vulnerable species according to Red Data Book from IUCN. This species may have two sub populations namely sang minyak and sang gajah. For conservation strategy, study on the genetic variation of this species was needed. The study aimed to examine the genetic variation of J. altifrons in Sikundur Forest, Gunung Leuser National Park, North Sumatera, using Isozymes marker. From three enzyme systems used (ACP, MDH, and PGD), two polymorphic loci were detected. Highest estimate of genetic variation parameters i.e. observed and expected heterozygosity were found in sang gajah, whereas sang minyak showed lower genetic diversity. This preliminary result suggested that this species had low average of polymorphic (40 %). Based on polymorphic level and expected heterozygosity, both sub populations genetically closed to each other. The differences of both sub populations lay on the wide leaf. Understanding of genetic variation suggested the importance of conservation effort of this species to increase number of populations.Key words: vulnerable species, genetic variation, Johannesteijsmannia altifrons., preliminary results

Abstract

Deforestation and fragmentation of mangrove forests in Indonesia are widespread that resulted in losing biodiversity including genetic variation. Rhizophora mucronata Lamk. is a common mangrove species in Secanggang, Langkat, North Sumatra and have been degrading due to anthropogenic disturbance. The aim of this study is to determine the genetic variation in natural population of R. mucronata in Secanggang, North Sumatra using isozyme markers. From five enzymes systems used namely aspartate aminotransferase (AAT), alcohol dehydrogenase (ADH), esterase (EST), malate dehydrogenase (MDH), and peroksidase (PER); eleven loci was found and five polymorphic loci were detected.The estimate value of genetic variation parameters i.e. observed and expected heterozygosity, average alel per loci, and average polymorphic (95% criteria) were 0.1386, 0.1724, 1.5455, and 45.45 % respectively.The low genetic variation of R. mucronata found in this study suggested that genetic variation may be influenced by anthropogenic activities such as illegal logging, conversion into shrimp pond and agricultural farm.Keywords: Anthropogenic, genetic variation, isozyme, mangrove, Rhizophora mucronata
