“…Daily average temperatures vary little throughout the year, with a mean of 26.7°C recorded at the DVFC climate station over the 5-y period, but there is considerable diurnal variation (typically ranging from 22.5°C in the early morning to c. 31°C shortly after noon). The average relative humidity in the open at the DVFC is close to 100% from 18h00 to 08h00 whereas it fluctuates between 60 and 100% during daytime, with annual means of 95% at 08h00 and 72% at 14h00 (Burghouts et al 1992, Marsh & Greer 1992. Characteristics of the forest micro-climate have been given by Brown (1990) and Brown & Whitmore (1992).…”

“…In our previous studies of leaf fall and leaf-litter decomposition in a lowland dipterocarp forest setting in the Ulu Segama Forest Reserve (Sabah, Malaysia), amounts of leaf litter on the forest floor were found to be strongly correlated with local amounts of total leaf fall (Burghouts et al 1992). This suggests that spatial variation in litter turnover may be smaller than expected from variation in litter fall alone.…”

Spatial heterogeneity of element and litter turnover in a Bornean rain forest

ABSTRACT. The spatial heterogeneity of element fluxes was quantified by measuring litterfall, throughfall and litter decomposition for 1 y in 30 randomly located sampling areas in a lowland dipterocarp rain forest. The idea tested was that turnover of elements is more variable than turnover of dry matter in a forest with extremely high tree species diversity. In spite of the low fertility of the soil (an ultisol), total litter production (leaves, trash, and wood <2 cm in diameter) was high (1105 g m −2 y −1 ) with inputs to the forest floor of carbon, nitrogen, phosphorus, calcium, magnesium, potassium, manganese and iron of 550, 15.3, 0.47, 6.26, 2.49, 4.75, 0.95 and 0.14 g m −2 y −1 respectively. Throughfall was 81% of the annual rainfall and transferred 22.2, 1.37, 0.14, 1.07, 0.67, 0.39, 7.92, <0.06, and <0.06 g m −2 y −1 of organic carbon, nitrogen (all forms), phosphorus, sulphur, calcium, magnesium, potassium, manganese and iron, respectively. Average turnover rates of nutrients in litter were highest for potassium and decreased in the sequence calcium, magnesium, carbon, nitrogen and phosphorus. Concentrations of phosphorus, nitrogen and potassium in litterfall, litter mass and topsoil were closely correlated with each other. Concentrations of calcium and manganese were positively correlated with each other and with elevation. Variations in leaf chemistry and total litterfall caused the spatial heterogeneity of element input to the forest floor to have a coefficient of variation of 30 -70%, depending on the element. Due to the strong positive correlation between element fluxes and pools, the spatial variability of turnover rates (CV c. 20%) was lower than that of element input. Turnover rates for K varied by a factor of 4, and for Ca by a factor of 2.8 when the different sites were compared. The results strongly suggest that the most important factor determining spatial heterogeneity of organic matter and element dynamics on the forest floor is the site-specific amount of leaf fall, rather than spatially variable decomposition rates.

“…Hal ini sejalan dengan temuan dari MRF, yaitu dengan tidak ditemukannya spesies berencet ini di areal hutan yang ditebang enam tahun yang lalu (O'Brien & Fimbel 2002). Burghouts et al (1992) dan Chung , dalam Hussin & Francis 2001) menemukan bahwa perubahan iklim mikro terkait dengan perubahan penyebaran serta kelimpahan vertebrata yang menjadi sumber makanan berencet. Di lain pihak, Boer (1998) menemukan bahwa terdapat korelasi yang tidak nyata antara kelimpahan serangga, gangguan habitat, dan keragaman serangga sehingga diperlukan penelitian lebih lanjut mengenai hubungan tersebut.…”

“…Tidak ada pola aktivitas yang berbeda secara statistik antara kegiatan di hutan bekas tebangan dan hutan utuh (Colón 1999). Dari invertebrata yang dikenal dimakan oleh musang, hanya Scorpianidae dan Isoptera yang populasinya secara nyata lebih berlimpah di hutan primer, dan Coleoptera dan Hymenoptera lebih umum dijumpai di hutan bekas tebangan (Burghouts et al 1992). Azlan (2003) menemukan bahwa spesies ini adalah karnivora kecil yang paling umum hidup di hutan sekunder berumur 30 tahun di Semenanjung Malaysia.…”

“…This agrees with fi ndings from the MRF, where, in an area that had been logged up to six years ago, wren-babblers had yet to return (O'Brien & Fimbel 2002). Burghouts et al (1992) and Chung (1993in Hussin & Francis 2001 found that changes in microclimate were associated with substantial changes in invertebrate distribution and abundance upon which these babblers depend. On the other hand, Boer (1998) found only a low and insignifi cant correlation between insect abundance, habitat disturbance and insect diversity, and further work is needed to explore these relationships.…”

ISBN 979-3361-56-5The Center for International Forestry Research (CIFOR) was established in 1993 as part of the Consultative Group on International Agricultural Research (CGIAR) in response to global concerns about the social, environmental and economic consequences of forest loss and degradation. CIFOR research produces knowledge and methods to improve the well-being of forest-dependent people and to help countries manage their forests wisely for sustainable benefi ts. This research is conducted in more than two dozen countries, in collaboration with numerous partners. Since it was founded, CIFOR has also played a central role in infl uencing global and national forestry policies.
