The Pasoh Forest Reserve in Malaysia is one of the most species-rich ecological systems on our planet. Since the 1970s it has been the site of intensive research on lowland tropical rain forest across a diverse range of disciplines including ecology, forestry, meteorology, and hydrology. Research has focused on biodiversity and sustainable management of tropical rain forests as well as the role of tropical rain forests in maintaining global climate and carbon sinks. This book compiles diverse studies of the ecology and natural history of the Pasoh Forest Reserve and focuses on six areas: Physical settings and environment; Vegetation structure, diversity, and dynamics; Plant population and functional biology; Animal ecology and biodiversity; Planta "animal interactions; and Anthropogenic impacts and forest management. This book is of interest to tropical forest researchers worldwide in ecology, conservation biology, taxonomy, and forestry.
