Spatial variability of soil hydraulic properties in a forested hillslope
(IPB (Bogor Agricultural University), 1999)
Spatial variability of soil hydraulic properties was measured in a forested hillslope and analyzed by applying combined water-retention-hydraulic-conductivity models (the LN and VG models) and a power function model for ...
Dynamic interactions between regional development and Kutai National Park, East Kalimantan, Indonesia.
(IPB (Bogor Agricultural University), 1991)
Kutai National Park, covering an area of 200 000 ha, is a rich tropical ecosystem with highly diverse habitat types ranging from coastal forest (mangrove) to mixed dypterocarps. It is a habitat of three endemic mammal ...
Avian use of wetlands in reclaimed minelands in Southwestern Indiana
(IPB (Bogor Agricultural University), 1993)
We studied the use of mineland wetlands by birds and the relationship between avian communities and wetland characteristics. Data were collected from 20 wetlands in Pike County, Indiana, and included wetland size, depth, ...
Transmigration Settlements in Seberida, Sumatra: Deterioration of Farming Systems in a Rain Forest Environment
(IPB (Bogor Agricultural University), 1994)
This study of transmigration settlements in Seberida, Riau Province, Sumatra, Indonesia, attempts to analyse why there was a deterioration in the ,farming systems of transmigrants and what the consequences of this were for ...
The flammability of shrubs and trees in an Acacia mangium plantation based on silica-free ash content
(IPB (Bogor Agricultural University), 1998)
Preliminary research to understand the flammability of 14 species of shrubs and 8 species of trees based on silica-free ash content was done in order to recognize which shrubs or trees are more flammable. The results show ...
The Impact of Extraction and Storage Conditions on the Viability of Radiata Pine Pollen
(IPB (Bogor Agricultural University), 1999)
The impact of extraction temperature, moisture content and storage temperature on in vitro pollen germination and tube growth, was determined in a sequence of experiments. Pollen extracted at 25°C, dried to 10% moisture ...
Production Structure of Main Commercial Tree Species in a Mangrove Forest in East Sumatra, Indonesia
(IPB (Bogor Agricultural University), 1991)
Production structure of main commercial tree species was studied in a mangrove forest in East Sumatra, Indonesia. This research was carried out in January 1991 using the estimation of standing biomass with stratified ...
Litter Production of a Mangrove Forest in East Sumatra, Indonesia
(IPB (Bogor Agricultural University), 1997)
Estimation of litter production in Bruguiera parviflora, B. sexangula, and B. sexangula-Nypa fruticans communities in the mangrove forest in Talidendang Besar, East Sumatra, Indonesia, was done from May 1990 to June 1991 ...
Field determination of unsaturated hydraulic conductivity of forest soils
(IPB (Bogor Agricultural University), 1998)
This study introduces a field method to determine unsaturated hydraulic conductivity which is applicable to sloping terrain with a limited water supply. A single steel ring infiltrometer and an artificial rainfall simulator ...
