Abstract

ABSTRACTBamboo distributed in various places in West Sumatera, including at Anai Valley Nature Reserve  Tanah Datar District. Anai Valley Nature Reserve has a high biodiversity that estimated diversity at Anai Valley is quite high. Descriptions using the bamboo flower organs was difficult because most rare bamboo flowering and some have not flowering. It is necessary to look for other alternatives as descriptions of materials, namely by using the anatomical structure of vegetative organs such as culm. To determine the type of bamboo that is at Anai Valley Nature Reserve has conducted investigated on morphological and anatomical characters some of bamboo species, using descriptive and quantitative methods were conducted in March-July 2013. Specimens of bamboo identified in Herbarium Andalas University (ANDA) Padang. Making preparations carried out in the Laboratory of Structural Plant Development, Department of Biology, Andalas University, Padang. Results of present study, six species of bamboo in Anai Valley Nature Reserve are: Bambusa balcooa (Roxb.) Voigt, Schizostachyum brachycladum Kurz, Bambusa glaucophylla Widjaja, Schizostachyum silicatum Widjaja, Bambusa vulgaris Schrad. Ex Wendl, Schizostachyum mampouw. Anatomical culm structure of B.balcooa, B.glaucophylla. and B.vulgaris, tends to have a dominant fiber outer sheath compared with Schizostachyum genus. Genus Bambusa consists of 6-9 rows that have a separate fiber sheath of vascular bundle centripetally, while the genus Schizostachyum obtained 3-4 rows. Longest fiber in Bambusa vulgaris get on that 2830±32 mm and the shortest on Bambusa glaucophylla is 1855±20 mm . While the width of the fiber diameter on Scyzostachyum silicatum at 28±4 mm and narrowest on Bambusa vulgaris is 19±4 mm.

Abstract

The Indonesian archipelago is an ideal setting for the study of speciation and biogeography. This archipelago is divided into three island groups based on zoogeography: Sundaland, Wallaceaand the Australian region. In this paper we used frogs in genus Fejervarya (Bolkay) to study biogeography and examine patterns of gene flow across proposed zoogeographic boundaries. Severalmolecular studies on Fejervarya species from Indonesia have been carried out, but comparative studies among members of the genus Fejervarya have yet to be performed. In order to elucidate genetic divergence and geographic distribution of these frogs, we conducted a molecular analysis of the mitochondrial 16S rRNA gene using 179 frogs from five Fejervarya species. In total we collected from 32 localities in Sumatra, Kalimantan (Indonesian part of Borneo), Java, Bali, Sulawesi and Lesser Sunda Islands in Indonesia. Molecular phylogenetic analysis recovered 35 haplotypes and showed that frogs in the genus Fejervarya were divided into two well-supported clades. The first group were of three species, F. limnocharis, F. iskandari and F. cf. verruculosa and the other group clade consisted of Fejervarya cancrivora and Fejervarya sp. (Sulawesi-type). The average sequence divergence among these four species ranged from 1.09 to 16.03% (mean = 11.29±2.83%). The present results clearly show that there are five Fejervarya species in the Indonesian archipelago. Fejervarya limnocharis and F. cancrivora are widely distributed and sympatric in Sumatra, Borneo and Java. Fejervarya iskandari is not endemic to Java and also occurs in the Lesser Sundas. Fejervarya cf. verruculosa and Fejervarya sp. (Sulawesi-type) are endemic to Lesser Sunda and Sulawesi Island, respectively. Key words: Fejervarya, genetic divergence, geographic distribution, 16S rRNA gene
