Abstract

Indonesia has a vast forest area. The extent of Indonesia's forests is one of the natural resources are prone to damage due to human interests in meeting their needs. One of the damage that often occurs when current is forest fires. Forest destruction accounts for 20-25% of global CO2 emissions that contribute to climate change or global warming. Unspoiled forest with a diversity of plant species are long-lived and litter is a place to store a lot of carbon stocks (C) the highest. The aim of this study was to determine the diversity of plants and the amount of carbon stock above ground level in the forests of the Bukit Barisan of Padang, West Sumatra. Tree biomass was calculated on a plot of 20x20 m, 10x10 m pole, stake 5x5 m, for counting down plant biomass and litter on the plot with a size of 2x2 m (National Standardization Agency, 2011). Biomass calculated by the Ketterings et al. formula (2001). In Bukit Barisan Forest Area, West Sumatra, derived carbon content was 16.029,70 ton/ha. Diversity type was highest at tree level on Station 1, classified as very high diversty with diversity index (H’) 3.10.

Abstract

Recently, climate change is the one of most important environmental issue. Climate variability can be recorded by tree growing through the growth ring. Growth ring formed by cambial activity were examined in wood anatomy. In Sumatra, there are three ecotypes Pinus merkusii, namely ecotypes Kerinci, Tapanuli, and Aceh which can be distinguished morphologically. This study aims to knowing the wood anatomical characteristics of the three ecotypes and determine the potential as climate indicator. This study was conducted in October 2014 until June 2015. Sample of Kerinci ecotype was collected in Kerinci Seblat National Park, Tapanuli ecotype in Dolok Sibualbuali Natural Reserve and Aceh ecotype in Gunung Leuser National Park on a height of 130 cm using increment borer and cut on the main stem 5×5 cm for anatomical sample. Results from this study indicate that ecotype Kerinci and Tapanuli showed earlywood and latewood boundary exposing the clear growth ring, whereas in Aceh ecotype unclear. Tapanuli ecotype have the thickest tracheid diameter than ecotype Kerinci and Aceh. Ecotypes of Kerinci, Tapanuli, and Aceh has homoceluler and uniseriate ray where Aceh ecotype have the longest ray. Furthermore, Kerinci and Tapanuli ecotype have potential as climate indicator eventhough showed negative correlation, that Tapanuli ecotype show the best result and recommended in dendrochronology study.

Abstract

Growth ring trees are formed by activity of the cambium which is influenced by the changing seasons.   In the tropical are not all of  trees species produce  the growth ring, because the season of  tropics is more uniform throughout the year and does not show sharp distinction between the periods of high rainfall and period of low rainfall. This study has concentred on several tree forest areas in Siberut National Park, Mentawai Islands. Samples were ollected by using borer on the main stem on the height of 130 cm. To see or not to see growing circle with to be checked macroscopically and microscopically. The macroscopic examination was done polished core by several grades of sandpaper in the transverse surface Tree species which have growth ring continued to microscopic observation with making slice anatomy. Based on 46 species of trees were examined, and  6 species were with found a growth ring in the number of cell mixture early wood and late wood from these species.

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

Abstract

Anaphalis javanica and A. longifolia, were collected during the expeditionto Mt. Merapi, Singgalang, Tandikat, and Talang (West Sumatra). Beside two of these species, several individuals of Anaphalis that differs in several characters from the two others species were also found. Based on it, morphometric study and biology reproduction analysis were carried out to clarify their taxonomic classification. Fifty three individuals of Anaphalis were collected and twenty four characters had been observed and measured to define species and morphology variation. Data analysis revealed that the alien species were defined as a natural hybrid of A. javanica and A. longifolia. There was no significant difference that number and morphology of pollens among populations as well as those two species studied. Based on the P/O ratio analysis indicated that breeding system of A. javanica and A. longifolia were facultative xenogamy. The same ornamentation (echinate) in both of two species suggested that the natural hybridization between two species was possible.
