Abstract

Indonesia has become an important part in the flyway of migratory birds due to the existing of high variety of habitat types that support for their life.Until now, the migratory birds records from Natuna Regency, which is the border area of Indonesia located in the South China Sea, are limited. This study was aimed to determine distribution and stopover habitat of migratory birds in the Natuna Regency area. The study was conducted in 2011 and 2013.Result from observations showed 14 species of migratory birds that belongs to five district birds families were identified in this area.They were Ardeidae (two species), Charadriidae (four species), Scolopacidae (six species),Laridae(one species) and Hirundinidae (one species).Southern Bunguran area has the highest record of migratory birds than other regions in Natuna. The migratory bird used four types of stopover habitat in Natuna Regency. i.e mangrovs, coastal, lakes / wetlands and other open areas.

Abstract

White shells Meretrix meretrix is one of the bivalves that are often sold in local markets of Makassar. Meretrix meretrix is one type of shellfishes that is favoured by the people so that they are continuedly being taken from their habitat without considering the feasibility of the capture. This research was aimed to determine the correlation between shell length, shell width, shell thickness, and total weight of the meat as well as assessing the size of a decent catch of M. meretrix in Makassar. Morphometric relationship between the length, width and thickness of the shell and total weight of the meat was analyzed using regression analysis.The results showed that the length and width of the shell and the length and total weight had strong positive correlation (0.81 = r = 0.96 and 0.81 = r = 0,92 repectively).The lenght and thickness of shell was moderately correlated (0.57 = r = 0.76), while the length and weight of the meat showed weak correlation (0.02 = r = 0.47). Size of M. meretrix sold in TPI Rajawali, Sentral market and Tanjung market ranged between 2.00 – 6.99 cm and has fulfilled the catching standard, which is > 4 cm.

Abstract

The freshwater molluscs (snails and bivalves) can be found in many type of water course either flowing or stagnant water. Some of them have survived living in bad condition such as polluted water. There are 199 situ (small lakes) in Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi) have been reported but only 20 % were in good condition, even 12% have dissapeared that caused by silting up of the situ. The aim of the study was to evaluate the diversity of the molluscs as well as to know the condition of on 36 situ along Ciliwung River and Cisadane River. Based on the collected samples, there were 13 species of snails and three species of bivalves. The freshwater snails Filopaludina javanica, Melanoides tuberculata, Pomacea canaliculata always occur in these situ but the bivalves Anodonta woodiana, Pilsbryoconcha exilis and Corbicula javanica only occur in situ Ciranji and Kemuning along Cisadane and Ciliwung rivers, respectively. The decreasing of the mollusc diversity was about 38% in Ciliwung River and 73% in Cisadane River, caused by polluted and silting up of the situ .

Abstract

Kedawung is a member of the plant genus of Parkia (Mimosaceae). It has important value as traditional medicine and currently has been included in the Indonesian list of endangered medicinal plant species. There are two closely related species to Kedawung in Java: P. intermedia and P. speciosa. Parkia intermedia has long been assumed to be a hybrid between P. speciosa and P. timoriana. The species has leaflets linear-oblong and obtuse apex in mature foliage resemble P. speciosa, but has more numerous leaflets, linear-falcate, and acute apex in its juvenile leaflets similar to P. timoriana. Thus Hopkins (1992) included Petir as uncertain species. The aim of this study was to assess its current existing populations, to clarify the taxonomic status and to evaluate the similarity between kedawung and its related species. Exploration, morphology and leaf anatomical studies, as well as phenetic analysis have been conducted. The results indicated that morphology and leaf anatomical characters can be used to distinguish P. timoriana, P. intermedia and P. speciosa as different species, and P. intermedia was more closely related to P. speciosa than to P. timoriana.

Abstract

Research at the three locations of Altingia excelsa Noronha plantations in Candikuning, Bali has been carried out to examine the changes in vegetation that grows naturally in the low layer after 22 years (1986 -2008). The results showed that 40 species of seedling, and 4 species of shrubs and young trees were found in three plots of the plantation forest. Compared to the results of the previous study, 22 years before the present study (1986), species richness was decreased dramatically accompanied by changes in species composition. Crown cover of herbs group were decreased, but shrubs and young trees were increased except for the plot 1938 due to edge effects. Lightdemanding species were disappeared and replaced by shaded-tolerant species. The primary tree species which are commonly found in the surrounding natural forest and previously found in research plots had been disappeared, and replaced by late secondary tree species, and seedlings of A. excelsa which is actually animmigrant species. Succession under the plantation forest of A. excelsa are generally slow.

Abstract

A study on the biomass and carbon stock estimation of Pinus merkusii Jungh. & de Vriese plantation has been conducted on 17-years and 30-years old pine forest in Gunung Bunder, Halimun Salak National Park. The method used was the allometric with non destructive technique. The results showed that pine trees density of 30-years old pine was 542 trees ha-1 ; the basal area (BA) was 26.8 m2 ha-1; trees density of 17-years old pine was 1,398 tree ha-1 with BA was 36.2 m2 ha-1. The estimation of biomass, carbon sinks and CO2 sequestration of 30-years old pine were 203.7, 96.5 and 354.2 ton ha-1, respectively. Meanwhile, the estimation of biomass, carbon sinks and CO2 sequestration of 17-years old pine were 188.3, 86.8 and 318.5 ton ha-1, respectively. Value of the environmental services derived from the CO2 absorption for the development of a pine forest ranged from US.$ 1,847.09 to 2,054.22, at two ages of pine trees.
