Terrestrial isopods were studied in the Dubravica peat bog and surrounding forest in the northwestern Croatia. Sampling was conducted using pitfall traps over a two year period. Studied peat bog has a history of drastically decrease in area during the last five decades mainly due to the process of natural succession and changes in the water level. A total of 389 isopod individuals belonging to ...

Astiani D, Burhanuddin, Taherdjadeh M, Curran LM. 2016. Effects of water table level on soil CO2 respiration in West Kalimantan forested and bare peatland: An experimental stage. Nusantara Bioscience 8: 201-206. Peatland forest is one of ecosystems that are susceptible to the alterations of water regimes. Our previous study demonstrated that hydrologic conditions are predominant variables in de...

There is a hypothesis that fragments of a body from outer space fell to Earth as a result of the Tunguska event. During decades of investigations at the site of the disaster, stone or iron pieces from a cosmic body were not found. In spite of this, the number of adherents of this hypothesis is growing. For one thing, it was determined that the formation of swamp craters at the epicentre of the ...

The province of Central Kalimantan contains about three million hectares of peatland, which is one of the largest unbroken tropical peatland areas in the world. Peat swamp forest (PSF) is among the earth's most endangered and least known ecosystem (12). They have a huge carbon storage capacity and are extremely fragile and liable to disturbance (10). Local communities have used them extensively...

The peat-forming wetland forests of Amazonia are characterized by high below-carbon stocks and supply fruit, fibres timber to local communities. Predicting the future these ecosystem services requires understanding how hydrological conditions related tree species composition presence, or absence, peat. Here, we use continuous measurements water table depth over 2.5 years manual pore-water pH el...

Macrofossil analysis of a composite 19 m long sediment core from Rano Raraku Lake (Easter Island) was related to litho-sedimentary and geochemical features of the sediment. Strong stratigraphical patterns are shown by indirect gradient analyses of the data. The good correspondence between the stratigraphical patterns derived from macrofossil (Correspondence Analysis) and sedimentary and geochem...

Analyses of a sediment core from Highstead Swamp in southwestern Connecticut, USA, reveal Lateglacial and early Holocene ecological and hydrological changes. Lateglacial pollen assemblages are dominated by Picea and Pinus subg. Pinus, and the onset of the Younger Dryas (YD) cold interval is evidenced by higher abundance of Abies and Alnus viridis subsp. crispa. As climate warmed at the end of t...

One of the provinces in Indonesia that experiences forest and land fires every year is Aceh Province. Barat District one districts Province where occur dry season. Forest prevention can be done by utilizing hotspot data for analysis using geographic information systems (GIS). This research aims to analyze distribution hotspots correlation between rainfall as an indicator occurrence West Regency...

The aim of this paper is to present a hybrid electrical air-cushion tracked vehicle (HETAV) for the operation on swamp peat. Mathematical models are incorporated with accounting kinematics and dynamics behaviors of the vehicle. Sinkage of the HETAV is sensed by an ultrasonic displacement (UD) sensor, in order to operate the air-cushion system. The air-cushion of HETAV is protected with a novel-...

Leyte Sab-A Basin peatland (LSBP) is the second largest in Philippines and comprises 3,088 ha (31 km2). The study estimated C storage carbon sequestration capacity of peatland’s four (4) ecotypes, namely, swamp forest (SF), marshland (ML), agroforestry (AF), agricultural land (AL) using allometric equations. SF rendered highest downed wood C-stocks followed by AL AF. For litter C-stocks, AF hig...
