Abstract

Phenological traits of Kandelia obovata (S., L.) Yong was investigated on the basis of seasonal leaf recruit, leaf death and leaf growth. The seasonal leaf growth was estimated using the logistic growth curve. Leaf recruitment, leaf death and reproductive cycle were obtained by survey data. This study results showed that new leaf recruitment occurred during the year indicating high productivity of mangrove Kandelia obovata forest. The highest leaf recruit was in July, while it was the lowest in January. However, the highest leaf death was in August, whereas it was the lowest in January. Growth pattern of leaves varied among seasons as of winter leaves are taken longger time to get their maximum size, while other season leaves are taken short time to get their maximum size. Period from flowering to mature propagules of K. obovata trees is considered to be around 12 months, while most the propagules become mature in the next spring season (April and May), which indicated shorter reproduction cycle.

Abstract

Hutan mangrove di Taman Nasional Rawa Aopa Watumohai (TNRAW) merupakan kawasan yang terjaga kelestariannya dan mendukung kehidupan hewan endemik.Tujuan penelitian ini adalah merumuskan model pengelolaan ekosistem mangrove yang efektif untuk mengoptimalkan konservasi hewan endemik dan dilindungi, utamanya Anoa dataran rendah (Bubalus sp) di Kawasan mangrove TNRAW,  Sulawesi Tenggara. Hasil penelitian menunjukan bahwa struktur vegetasi mangrove di kawasan TNRAW memperlihatkan keunikan masing-masing di area pantai, daerah tengah dan dekat daratan. Terdapat 8 jenis mangrove berkayu di kawasan mangrove TNRAW yang menjadi area pengamatan burung dengan kondisi sangat baik di area tepi pantai, tengah maupun perbatasan dengan daratan, meskipun pada beberapa bagian cukup sulit untuk terjadi regenerasi alami karena kondisi tegakan yang cukup rapat. Empat jenis mangrove sejati yang paling dominan di TNRAW yaitu Rhizophora apiculata, Rhizophora mucronata, Lumnitzera racemosa dan Ceriops tagal. Rhizophora apiculata dan R. mucronata tumbuh disepanjang aliran sungai Lanowulu yang membelah hutan mangrove di TNRAW.Lumnitzera racemosa dan Ceriops tagal tumbuh di daerah dengan habitat yang keras. Anoa dataran rendah (Bubalus sp) tersebar di kawasan mangrove  yang relatif mudah pada tegakan Lumnitzera racemosa dan Ceriops tagal yang ditandai dengan adanya tapak kaki dan kotoran dan terdapat ruang-ruang kosong yang ditumbuhi rerumputan dan semai serta anakan kedua jenis tersebut yang memungkinan hewan Anoa dataran rendah menggunakan mangrove sebagai tempat beristrahat dan mencari makan.Kata kunci : Hutan mangrove, Hewan endemik, Anoa dataran rendah, TNRAW.

Abstract

ABSTRACT This study aimed to know the bioaccumulation and translocation of heavy metal mercury (Hg) and cadmium (Cd) on mangrove Rhizophora spp grown in Rawa Aopa Watumohai National Park. The heavy metals content of Hg and Cd in vegetative organs of R.mucronata, R.apiculata and R.stylosa were analyzed by using Atomic Absorption Spectrophotometry AAS, while their translocation factor (TF) in mangrove organs were elucidated. The results showed that heavy metal bioaccumulation in mangrove organs varied among mangroves. Heavy metals contents in organs of mangrove Rhizophora mucronata were estimated as 0.492 μg/g for Cd and of 0.085 μg/g for Hg. On the other hand, those of metals contents in R. Apiculata were 4.67 μg/g for Cd and 0.414 μg/g for Hg. Meanwhile heavy metals contents in R. stylosa were 0.796 μg/g for Cd metal and 0.084 μg/g for Hg metal. However, the mangroves of R. mucronata and R. apiculata seemed to ineffective on translocation of mercury metal in their organs as of the values of TF among organs were < 1, while the mangrove R. stylosa seemed to more effective on translocation of Hg and Cd heavy metals in its organs (TF > 1.0). Therefore, each mangrove has different ability to accumulate heavy metals in its organs. Thus, maintenance mangrove diversity is important to reduce heavy metal pollutant and keeping coastal area productivity.Keywords : Heavy Metal Bioaccumulation, Heavy Metal Translocation,                               Mangrove, Rawa Aopa Watumohai National Park

ABSTRACT The objective of this study was to elucidate the species composition, vegetation structure and ordination pattern of mengroves in the Passare Apua village at Lantari Jaya district, Bombana regency, South East Sulawesi. The transect method and sampling quadrat were used in this study. The growth parameters of mangroves were measured at 30 plots (100 m2 wide each). The number of individual mangroves on the basis of growth stages including trees, poles, saplings and seedlings were counted, while the environmental condition such as temperature, salinity, pH and organic matter content were analyzed. The ecological indicators such as density, frequency, dominance, importance value indice and ordination pattern were estimated. The results showed that there existed 7 species and 3 families of mangroves at the study site. The Rhizophora apiculata Blume was the highest importance value indice (125-150%), indicated as the most dominant mangrove that supports mangroves ecosystem stability in this area. The ordination pattern of mangrove vegetation across the study area formed 3 groups, Group A comprised by stands I, III and IX; Group B consists of stands II, V, VI, VII and VIII, while group C composed by stands IV and X.Keywords : Mangrove composition, Mangrove Structure, Importance Value,                     Ordination Pattern

Abstract

The present study was aimed to elucidate the spatial pattern in the beta diversity of marine bentic for Echinoidea and Asteroidea that assemblages the coastal area of Tomia Island, Wakatobi Marine National Park, Indonesia. The two transect lines of 460 and 260 m in length with small quadrats of 1m2 wide were placed at the open and unopen beaches perpendicularly to the coastlines. The important value index and similarity index SI of organisms on these taxa were estimated in each the transect. Echinometra mathaei was the most dominant Echinoidea at open and unpen beaches, while Protoreaster nodusus was the most dominant Asteroidea at both areas. Most of SI values of Echinoidea at open beach were estimated less than 50%, which was lower than SI values that of organisms at unopen beach. On the other hand, most of SI values of Asteroidea at both areas were estimated more than 70% representing high similarity degree of its species composition among sites. The disimilarity index of organisms in the taxa of Echinoidea and Asteroidae was increased significantly as increasing the distance of among stands, which suggested that pettern in beta diversity of these taxa was associated with the spatial heterogenity.
