Abstract

Sutarno, Setyawan AD, Suyatna I. 2012. Species diversity of critically endangered pristid sawfishes (Elasmobranchii: Pristidae) Elasmobranchii: Pristidae (Malay Archipelago). Biodiversitas 13: 161-171. The pristid sawfishes (Pristidae) are notable because of their sawlike rostrum and large body size (up to seven meters). All pristids are listed as critically endangered by IUCN, since decreasingpopulation; Nusantara is home for five pristid species, namely: Anoxypristis cuspidata Latham, 1794, Pristis clavata Garman, 1906, Pristis microdon Latham, 1794, Pristis zijsron Bleeker, 1851, and Pristis pectinata Latham, 1794. A. cuspidata differ from Pristid spp. by the presence of a very narrow rostral saw, with 16 to 29 pairs of teeth except for the part along the quarter of the rostral saw near the head. P. microdon has a highly defined groove that runs along the entire posterior edge of the tooth into and beyond its confluence with the rostrum. This groove is absent in juvenile of P. clavata and whilst it develops in larger individuals it rarely runs along the entire posterior edge of the tooth or reach its confluence with the rostrum. P. clavata possibly have been misidentified as P. pectinata, whose distribution in the Indo-West Pacific is uncertain. P. clavata can be distinguished from P. pectinata and P. zijsron by the possession of fewer rostral teeth (18 to 22 in P. clavata cf. 24 to 28 in P. zijsron and 24 to 34 in P. pectinata), and by its smaller body size (i.e. less than 250 cm TL in P. clavata). P. microdon indicates different sexes of the number of rostral teeth, i.e. 17-21 in female cf. 19-23 in male, but in P. clavata, it can not be used to differentiate male from female, with both sexes possessing an average of 42 rostral teeth. In P. clavata the dorsal fin origin is opposite or slightly behind the pelvic fin origin, the rostum is relatively shorter (22-24% of TL), he lower cauda fin lobe is smaller.

Abstract

Setyawan AD, Ulumuddin YI. 2012. Species diversity of Rhizophora in Tambelan Islands, Natuna Sea, Indonesia. Biodiversitas 13:172177. Research on diversity and distribution of mangroves on the small remote islands are rarely performed than on the coastal area and estuaries. Tambelan Islands is a cluster of small islands isolated in the Natuna Sea, Indonesia. On the island there are four species of Rhizophora, namely R. apiculata, R. stylosa, R. mucronata, and hybrid species R. x lamarckii. Rhizophora stylosa and R. apiculata are the most common species found. R. mucronata only found in certain places (i.e. Durian River), R. x lamarckii rare, usually grows in stands that also covered by the two parental, R. stylosa and R. apiculata. All Rhizophora species were found to have thorn on the leaf tip, and spotted brown on the underneath leaf. R. apiculata has a petal without woolly feathers, inflorescence have short stalks and cork. R. stylosa and R. mucronata are sibling species, both of them have a long-stalks and dichotomy inflorescence, but the style of R. mucronata very short (<2.5 mm), whereas in R. stylosa longer (> 2.5 mm). R. x lamarckii has characters between R. apiculata and R. stylosa.

Abstract

Pitopang R. 2012. Impact of forest disturbance on the structure and composition of vegetation in tropical rainforest of Central Sulawesi, Indonesia. Biodiversitas 13: 178-189. We presented the structure and composition of vegetation in four (4) different land use types namely undisturbed primary forest, lightly disturbed primary forest, selectively logged forest, and cacao forest garden in tropical rainforest margin of the Lore Lindu National Park, Central Sulawesi Indonesia. Individually all big trees (dbh > 10 cm) was numbered with tree tags and their position in the plot mapped, crown diameter and dbh measured, whereas trunk as well as total height measured by Vertex. Additionally, overstorey plants (dbh 2- 9.9 cm) were also surveyed in all land use types. Identification of vouchers and additional herbarium specimens was done in the field as well as at Herbarium Celebense (CEB), Tadulako University, and Nationaal Herbarium of Netherland (L) Leiden branch, the Netherland. The result showed that the structure and composition of vegetation in studied are was different. Tree species richness was decreased from primary undisturbed forest to cacao plantation, whereas tree diversity and its composition were significantly different among four (4) land use types. Palaquium obovatum, Chionanthus laxiflorus, Castanopsis acuminatissima, Lithocarpus celebicus, Canarium hirsutum, Euonymus acuminifolius and Sarcosperma paniculatum being predominant in land use type A, B and C and Coffea robusta, Theobroma cacao, Erythrina subumbrans, Gliricidia sepium, Arenga pinnata, and Syzygium aromaticum in the cacao plantation. At the family level, undisturbed natural forest was dominated by Fagaceae and Sapotaceae disturbed forest by Moraceae, Sapotaceae, Rubiaceae, and agroforestry systems by Sterculiaceae and Fabaceae.

Abstract

Yonvitner, Fahmi. 2012. Population dynamics of dominant demersal fishes caught in Tambelan Islands waters, Riau Archipelago Province. Biodiversitas 14: 200-204. The population of demersal fishes tends to be decline in the last few decades. The decline was due to the increased of intensive catches, fishing effort and illegal fishing practices. This study aimed to examine aspects of population dynamics such as mortality, recruitment, opportunity capture and population estimation. The study was conducted in six locations at Tambelan waters, on 4-16 November 2010. Collected data included the fish species, size and biomass catch. The analyses performed included mortality, recruitment, opportunity capture and population estimates (VPA). The data indicated that the Genus of Nemipterus and Lutjanus possess the highest total mortality rate that was respectively 1.62 and 2.55. The highest recruitment presentation of the population which has an annual period as Pentapodus was 16%. Catch opportunities tend to be higher than actual fishing, while the alleged biomass of steady state conditions reached 12.2 tons/yr.

Abstract

Reyahi-Khoram M, Jafary M, Bayati M, Reyahi-Khoram R. 2012. Plants and animals diversity in Buqaty Mountain Area (BMA) in Hamadan Province, Iran. Biodiversitas 14: 190-194. Buqaty Mountain Area (BMA) is regarded as one of the genetic reserves of Hamadan province in Iran. BMA is highly important regarding variety of plant and animal species, but limited research work has been performed in this area in the field of biodiversity. Identifying the unique ecologic talents and capabilities and aesthetics of BMA is the most important objective of this study. This research was conducted during 2010 through 2011 in BMA to identify various plant and animal species through documentary and also direct field observations. With direct referring to the various regions of the studied area, plant samples were collected from different slope position and transported to field laboratory units. Sampling was made for every 20 meters increase in the height of area. Animal species of the area were identified too. Based on the results, about 44 valuable plant species, 45 species of birds as well as 7 species of mammals have been identified in BMA. It is recommended that the area be declared an A prohibited hunting area by Department of Environment (DoE) of Iran for the conservation of flora and fauna in the study area.

Abstract

Sulasmi IS, Nisyawati, Purwanto Y, Fatimah S. 2012. The population of Jernang rattan (Daemonorops draco)  in Jebak Village, Batanghari District, Jambi Province, Indonesia. Biodiversitas 13: 205-213. Research of Rattan Jernang ((Daemonorops draco Willd.) population in Jebak Village, Batanghari District, Jambi had never been done before. Daemonorops draco is a plant that produces sap called dragon blood. Dragon blood is very useful for the the lives of people of Anak Dalam Tribe in Jambi. This research used purposive random sampling method. All of data were analyzed descriptively. The results showed that beside D. draco, there were other six species of rattan in Jebak forest. The population of D. draco in Jebak forest was only 8 clumps, consisting of 82 individuals. D. draco had the smallest population among all rattan species. Calamus javensis had the highest population, namely 11 clumps, consisting of 197 individuals. The research location had air temperature of 20.2 oC-28.9 oC, relative humidity of 58%-68%, and pH of 4.60-4.81. In this location, there were 35 tree species (73 individuals)  as supporting trees for D. draco to climb. The number of D. draco’s supporting trees and D. draco was not balanced, causing the death of D. draco in Jebak forest. Vegetation analyses showed that there were 51 tree species with diameter > 10 cm, consisting of 69 individuals. Pithecolobium saman had the highest importance value index (11) among all trees. There were also 33 tree species with diameter < 10 cm, consisting of 60 individuals. Pithecolobium saman also had the highest importance value index (20) in this group. Based on the interview, it is showed that the population of D. draco in Jebak forest declined because of illegal logging and forest encroachment.

Abstract

Srivastava AK, Rai MK. 2012. Review: Sugarcane production: impact of climate change and its mitigation 13: 214-227. Sugarcane is a climatic sensitive crop: therefore, its spatial distribution on the globe is restricted as per the suitability of various climatic parameters. The climate change, though, a very slow phenomenon is now accelerated due to natural, as well as enormous human activities disturbing the composition of atmosphere. The predications of various climatic models for probable rise in temperature, rainfall, sea level show an alarming condition in forthcoming decades. As the sugarcane is very sensitive to temperature, rainfall, solar radiations etc. therefore, a significant effect on its production and sugar yield is expected in future. It is also well known that sugarcane is one of the precious crops of the world and its end products i.e. sugar and ethanol have a continuous growing demand on global level. Hence, the studies related to good production of sugarcane in changing conditions of climate has become one among the front line area of research and is a major concern of scientist’s world over. Advance agronomic measures including development of suitable cane varieties susceptible to changed climatic conditions, land preparation, time and pattern of plantation, weed, disease and pest managements, nutrients managements, proper timing and adequate water management seems to be the affective measures for obtaining high production of crop with good quality juice in future.
