The implications of climate and gap microclimate for seedling growth conditions in a Bornean lowland rain forest

Abstract: Present theories of tropical rain forest regeneration dynamics suggest that different tree species specialize on the microclimates of different sizes of canopy gap. A detailed analysis of the microclimates of closed forest and 10 canopy gaps of different sizes was carried out in lowland dipterocarp rain forest, Sabah, Malaysian Borneo. It reveals that gaps exhibit considerable spatial and temporal variation in microclimate. As a consequence the relationship between microclimate and gap sizes is not simple. Gap… Show more

“…Species composition, canopy openness, tree density and vertical stratification affect the light environment in the forest floor (Brown & Parker 1994, Canham et al 1990. A decrease in irradiance following canopy closure entails a decrease in temperature and vapour pressure deficit (Brown 1993, Heithecker & Halpern 2007. Similarly, foliage density and vertical distribution, along with the presence of litter, also modifies soil water content (Camargo & Kapos 1995, Marthews et al 2008.…”

“…Although light availability is likely to be the resource that shows the most variation across gaps of different sizes (Brown 1993, Grace 1991, Vitousek & Denslow 1986), traditional shade-house experiments in which plants are exposed to relatively constant light environments are unlikely to capture this variation in a realistic way. Natural gaps in forest receive prolonged periods of mostly diffuse radiation while the sun is obscured by canopy, and periods of direct radiation when the sun is above the gap.…”
