Towards quantifying tropical tree species richness in tropical forests
International Journal of Remote Sensing, 2009This letter reports tests of whether the normalized difference vegetation index (NDVI) from Landsat Enhanced Thematic Mapper Plus (ETM+) and radar backscatter (C-, L-and P-bands) from Airborne Synthetic Aperture Radar (AIRSAR) imagery can be used to estimate tree species richness from 25 1-ha plots within continuous lowland forest types (dry, moist ...

Tree fallows: A comparison between five tropical tree species
Biology and Fertility of Soils, 1996The natural abundance of 15N and 13C, conventional soil analyses, and biomass production by maize were used to study the influence of five tropical tree species on soils and their fertility. The experiment was conducted in Morogoro, Tanzania, to compare Cassia (Senna) siamea, Eucalyptus camaldulensis, E.

Distinctive Bacterial Communities in the Rhizoplane of Four Tropical Tree Species
Microbial Ecology, 2012It is known that the microbial community of the rhizosphere is not only influenced by factors such as root exudates, phenology, and nutrient uptake but also by the plant species. However, studies of bacterial communities associated with tropical rainforest tree root surfaces, or rhizoplane, are lacking. Here, we analyzed the bacterial community of root

Herbivores and the Number of Tree Species in Tropical Forests
The American Naturalist, 1970A high number of tree species, low density of adults of each species, and long distances between conspecific adults are characteristic of many low-land tropical forest habitats. I propose that these three traits, in large part, are the result of the action of predators on seeds and seedlings. A model is presented that allows detailed examination of the

TROPICAL RAINFOREST GAPS AND TREE SPECIES DIVERSITY
Annual Review of Ecology and Systematics, 1987Evolutionary hypotheses about how so many species of tropical rainforest trees might have arisen include (a) genetic drift (71), (b) habitat specialization (8) in benign environments, or (c) repeated geographic isolation followed by remixing of species during Pleistocene climatic fluctuations (144).

Temperature response of CO2 exchange in three tropical tree species
Functional Plant Biology, 2016Tropical forests play a critical role in the global carbon cycle, but our limited understanding of the physiological sensitivity of tropical forest trees to environmental factors complicates predictions of tropical carbon fluxes in a changing climate. We determined the short-term temperature response of leaf photosynthesis and respiration of seedlings ...

Seedling Traits Determine Drought Tolerance of Tropical Tree Species
Biotropica, 2008ABSTRACTWater availability is the most important factor determining tree species distribution in the tropics, but the underlying mechanisms are still not clear. In this study, we compared functional traits of 38 tropical tree species from dry and moist forest, and quantified their ability to survive drought in a dry‐down experiment in which wilting and
