Abstract

The lowland peatlands of south-east Asia represent an immense reservoir of fossil carbon and are reportedly responsible for 30% of the global carbon dioxide (CO2) emissions from Land Use, Land Use Change and Forestry. This paper provides a review and meta-analysis of available literature on greenhouse gas fluxes from tropical peat soils in south-east Asia. As in other parts of the world, water level is the main control on greenhouse gas fluxes from south-east Asian peat soils. Based on subsidence data ...

Abstract

A survey of the density and population size of Bornean orang-utan (Pongo pygmaeus) was carried out in 1995 and 1996 in an area of peat swamp forest in the Sungai (River) Sebangau catchment, Central Kalimantan, Indonesia. Densities were calculated for four forest sub-types by counts of orang-utan sleeping platforms (nests) along line transects. Densities were found to be highest in the tall interior and mixed swamp forest sub-types. Low pole forest supported the lowest density. Habitat disturbance caused by logging was ...

Abstract

Arbuscular mycorrhizas improve the growth and nutrient uptake of plants and are formed in 80% of all land plants. Little information is available on the status of arbuscular mycorrhizas in tropical soils. The objective of this study was to clarify mycorrhizal colonization of tree species grown in tropical peat soils. Seedlings of 22 tree species in 14 families grown in a peat swamp forest of Central Kalimantan, Indonesia were collected in 2000 and 2001. Roots were stained with 0.05% aniline blue ...

Abstract

Clarification of carbon content characteristics, on their spatial variability in density, of tropical peatlands is needed for more accurate estimates of the C pools and more detailed C cycle understandings. In this study, the C density characteristics of different peatland types and at various depths within tropical peats in Central Kalimantan were analyzed. The peatland types and the land cover types were classified by land system map and remotely sensed data of multi-temporal AVHRR composites (1-km pixel size), respectively. Differences in ...

Abstract

Greenhouse gas emissions were measured from tropical peatlands of Kalimantan, Indonesia. The effect of hydrological zone and land-use on the emission of N2O, CH4 and CO2 were examined. Temporal and annual N2O, CH4 and CO2 were then measured. The results showed that the emissions of these gases were strongly affected by land-use and hydrological zone. The emissions exhibited seasonal changes. Annual emission of N2O was the highest (nearly 1.4 g N m(-2) y(-1)) from site A-1 (secondary forest), while there was ...

Abstract

Various organic fractions of an Indonesian tropical peat deposit were dated using radiocarbon accelerator mass spectrometry (AMS). Four different depth layers, deposited during the last 28,000 C-14 yr, were analyzed and the data compared to bulk sample analyses. The pollen extracts consistently produced the oldest dates. The bulk samples (< 250 mu m and < 100 mu m) often yielded the youngest dates. The age difference between the individual fractions depended on the layer depth and hence the true age of ...

Abstract

Plant communities on nutrient-poor soils are thought to use nutrients more efficiently to produce biomass than plant communities on nutrient-rich soils. Yet, increased efficiency with declining soil nutrients has not been demonstrated empirically in lowland tropical rain forests, where plant growth is thought to be strongly limited by soil nutrients, especially phosphorus (P). We tested for higher P uptake and use efficiency across a 16-fold soil P gradient in lowland Borneo by measuring the P content of aboveground net primary productivity ...

Abstract

The horrific violence that has marred Indonesia's transition to democracy raises numerous disconcerting questions; not least of which is how future interested actors or governments central and regional alike will tackle these atrocities in a historical framework. How should a series of historical events, such as the killing of thousands of Indonesians <i>by</i> Indonesians be (un)officially remembered? Two paintings that hang in Sambas, West Kalimantan's most prominent cultural centrepiece, the Alwadzi Koebillah <i>kraton</i>, are remarkable, for they give us ...

Abstract

Between 1988 and 2000, changes in the above-ground biomass (AGB) of trees in an East Kalimantan lowland forest, damaged by fires in 1982-83 and 1998, were estimated using allometric functions and an annual inventory of stem diameter. The original vegetation of the study site was lowland dipterocarp forest which has since been affected by selective logging and wild fires. The 1982-83 fire killed large trees of primary species and the opened sites became dominated by a few pioneer species. Between 1988 ...

Abstract

We conducted the first orangutan population census of Gunung Palung National Park, West Kalimantan, Indonesia, between April and September 2001. We used a refined line-transect nest-count methodology utilizing transect recounts to survey 69 km at 14 sites within the park and 14.2 km in the buffer zone. We present the first Bornean orangutan density estimate using complete site-specific parameters and long term monitoring of nest decay rates. Average orangutan density was 3.0 individuals/km2, with densities ranging from 2.4 ind/km2 in montane ...

Abstract

The ecology of Bornean rainforests is driven by El Nino-induced droughts that trigger synchronous fruiting among trees and bursts of faunal reproduction that sustain vertebrate populations. However, many of these species- and carbon-rich ecosystems have been destroyed by logging and conversion, which increasingly threaten protected areas. Our satellite, Geographic Information System, and field-based analyses show that from 1985 to 2001, Kalimantan's protected lowland forests declined by more than 56% (>29,000 square kilometers). Even uninhabited frontier parks are logged to supply international ...

Abstract

Tropical peatlands are one of the largest near-surface reserves of terrestrial organic carbon, and hence their stability has important implications for climate change1, 2, 3. In their natural state, lowland tropical peatlands support a luxuriant growth of peat swamp forest overlying peat deposits up to 20 metres thick4, 5. Persistent environmental change—in particular, drainage and forest clearing—threatens their stability2, and makes them susceptible to fire6. This was demonstrated by the occurrence of widespread fires throughout the forested peatlands of Indonesia7, 8, ...

Abstract

Abstract Tropical peatlands, which coexist with swamp forests, have accumulated vast amounts of carbon as soil organic matter. Since the 1970s, however, deforestation and drainage have progressed on an enormous scale. In addition, El Nino and Southern Oscillation (ENSO) drought and large-scale fires, which grow larger under the drought condition, are accelerating peatland devastation. That devastation enhances decomposition of soil organic matter and increases the carbon release to the atmosphere as CO2. This phenomenon suggests that tropical peatlands have already become ...

Abstract

Deforestation in Indonesia poses a significant threat to the region's biodiversity. We mapped forest cover in Kalimantan, Indonesia, in 2002, with imagery provided by the Moderate Resolution Imaging Spectrometer (MODIS). The MODIS-based forest and nonforest map showed good agreement with other sources of recent data on forest cover. Comparison of MODIS forest cover with Indonesian government data from 1996 revealed that almost 3 million ha of forest were lost in Kalimantan since the major El Nino event of 1997-1998, when a ...

Abstract

Geographic variation in some aspects of chimpanzee behavior has been interpreted as evidence for culture. Here we document similar geographic variation in orangutan behaviors. Moreover, as expected under a cultural interpretation, we find a correlation between geographic distance and cultural difference, a correlation between the abundance of opportunities for social learning and the size of the local cultural repertoire, and no effect of habitat on the content of culture. Hence, great-ape cultures exist, and may have done so for at least ...

Abstract

We report estimates of orangutan distribution and population size in and around the Danau Sentarum Wildlife Reserve (DSWR) in West Kalimantan, Indonesia, one of the few areas in Borneo that may still support a large population. We generated estimates in line with each of three proposed definitions for the reserve - its current boundaries, a moderate extension, and a greater extension. Estimates were based on current nest survey methods, adjusted for habitat type variability. Measures of habitat type coverage derived from ...

Abstract

Boosted by the 1997/98 El Nino-Southern Oscillation (ENSO) phenomena, uncontrolled fires have destroyed huge areas of rainforest and bush land in Indonesia. Thick smoke covered large areas over SE Asia for months. Due to their cloud and haze penetrating capability SAR sensors could complement existing fire monitoring systems based on NOAA-AVHRR data, providing a 900 times higher spatial resolution. This article describes results of the combined synergistic use of NOAA-AVHRR hotspot data received and processed by the IFFM/GTZ project and multitemporal ...

Abstract

In a recent serological survey among 143 excaptive orang-utans two individuals were found that reacted positive in an ELISA detecting antibodies which cross-react with human T- lymphotropic virus type I (HTLV-I) antigens. Infection of both animals with an HTLV-I or simian T-lymphotropic virus (STLV)- like virus was confirmed by Western blot analysis. A third wild-caught animal, which was not part of the original serological survey, was also found to be infected with an HTLV- related virus in a diagnostic PCR assay ...

Abstract

We investigated the population density of Bornean orangutans Pongo pygmaeus pygmaeus and aspects of habitat quality in a selectively hand-logged peat swamp forest in West Kalimantan, Indonesia, and in a comparable unlogged forest nearby. We conducted orangutan nest surveys, measured different parameters of forest structure, recorded monthly changes in fruit availability, and noted the sex and the stage of maturity of orangutans encountered. Nest density, an index of orangutan population density, was 21% lower in the logged area. The forest, logged ...

Abstract

ver the past decades, uncontrolled forest fires have formed an increasing threat for tropical forests, often causing large-scale ecological and economic damage. My research shows that, even though the damage caused by the fire is enormous, a single fire does not cause the complete destruction of a tropical rain forest: A part of the trees survives the disturbance through above ground survival, or through resprouting from below ground parts. As a result of this local persistence, recolonisation by shade tolerant species ...

Abstract

Tree species composition (diameter at breast height (dbh) ge 10 cm) was studied in primary, selectively logged and heavily burnt forests in East Kalimantan, Indonesia. The number of trees, tree species, and the Fishers's-agr diversity index were determined for the first 15 years (burnt forest) and 25 years (selectively logged forest) after disturbance. Additionally the population structure of six common and typical Macaranga pioneer tree species was compared through time between selectively logged, burnt and primary forest. Both selectively logged and ...
