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 aims of this research were determine diversity and evenness index of insect atHoga Island Wakatoby Regency. This research used the mehtod of squared plot. It is wasmade 3 pieces purporsively line transect direct shoroline cut mangrove communities startfrom the most advanced (seaward) direction behind. Each transect plots observations weremade on the left and the right along the transects line. The diversity index and evennessindex was determined using Shanon-Wiener. The result showed that, there were 4 orders ofinsects which consist of 7 families and 13 genera. The highest diversity index (H’) of inscetswas found at Osbornia clodonata stand (0.25), while it was the lowest at Xilocarpusgranatums stand (0.14). Evenness index (E) of insect among has significance different all ofmangrove stands, namely a stand Bruguiera gymnorrizha (0.09), Pemphis accidula (0.07),Osbornia clodonata (0.12) and Xilocarpus granatum (0.07).Keywords : Diversity, Insects, Mangrove Community, Hoga Island

Abstract

ABSTRACTDrought stress is one of the major limiting factors for plant growth and production in the tropic area because it can reduce crop yield sup to average 50%. Therefore, the mechanism of drought tolerance is important to be studied. Drought stress can cause a decrease in water potential, osmotic potential, and potential pressure, which leads to increased accumulation of proline. Proline accumulation can be cause dactivists proline synthesis from glutamate, proline oxidation decreased speed, low protein synthesis and decreased delivery proline into the phloem. Proline synthesis of glutamate stimulated by abscisic acid (ABA). While theoxidation of proline and protein synthesis of prolineis not influenced by the ABA. Proline accumulationon the state of water stress serves as osmoregulation, protective enzymes and membrane structure, keeping water in the cells by binding water from the soil due to increased osmotic potential becomes more negative.Keywords : osmotic regulation, drought stress, proline, glutamate, abscisic acid

Abstract

ABSTRACTMangrove ecosystems are highly productive and contribute as sources organic carbon and nutrients. The present study was aimed to determine export of of carbon from R. mucronata and C. tagal mangrove leaf litter at Rawa Aopa Watumohai National (RAWN) Park. Litterfall sampling of mangrove at RAWN Park was done by purposive sampling method. Carbon content was analyzed using ash method. The export value of carbon and nitrogen was estimated. The results showed that monthly export of organic carbon by mangrove C. tagal (14,36 g C/ m2/month) was higher than R. mucronata (12,02 g C/m2/month. Therefore, R. mucronata and C.tagal play important role as source of carbon and support the coastal ecosystem productivity.Keywords : Mangrove Forest, Leaf Litter, Carbon Export, RAWN Park.
