    Sunfleck Contribution to Leaf Carbon Gain in Gap and Understory Tree Seedlings of Shorea macrophylla

    Dynamic gas exchange in response to sunflecks has been studied extensively through laboratory experiments and by modeling. However, model estimates of photosynthetic changes in response to sunflecks vary widel...

    Leaf Herbivory and Defenses of Dipterocarp Seedlings in the Pasoh Forest Reserve

    Leaf herbivores can potentially reduce the growth and survival of individual tree seedlings, thereby influencing the composition and species diversity of plant communities in forests. Plants have developed var...

    Prospects and Priorities for Research Towards Forest Policy Reform and the Sustainable Management of Biodiverse Tropical Forests

    To facilitate the sustainable management of biodiverse tropical forests, we propose that the ecological services and goods of these forests be assessed. The assessment should start with a review of existing ec...

    Microhabitat Preference of Two Sympatric Scaphium Species in a 50 ha Plot in Pasoh

    A remarkable feature of tropical woody biodiversity is the presence of a large number of closely related, sympatric species in some genera. Such species are most likely to have relatively similar niches, shari...

    Logging History and Its Impact on Forest Structure and Species Composition in the Pasoh Forest Reserve — Implications for the Sustainable Management of Natural Resources and Landscapes

    Abstract: A part of the Pasoh Forest Reserve (Pasoh FR) was once logged under a logging regime called the Malayan Uniform System (MUS) in the 1950s. The core area of the reserve is a residual unlogged (primary...
