Isoprene emission from tropical tree species
Environmental Pollution, 2005Foliar emission of isoprene was measured in nine commonly growing tree species of Delhi, India. Dynamic flow enclosure technique was used and gas samples were collected onto Tenax-GC/Carboseive cartridges, which were then attached to the sample injection system in the gas chromatograph (GC).

Hurricane Disturbance and Tropical Tree Species Diversity
Science, 2000The debate over the maintenance of high diversity of tree species in tropical forests centers on the role of tree-fall gaps as a primary source of disturbance. Using a 10-year data series accumulated since Hurricane Joan struck the Caribbean coast of Nicaragua in 1988, we examined the pattern of species accumulation over time and with increased ...

Pervasive within-species spatial repulsion among adult tropical trees
Science, 2023For species to coexist, performance must decline as the density of conspecific individuals increases. Although evidence for such conspecific negative density dependence (CNDD) exists in forests, the within-species spatial repulsion it should produce has rarely been demonstrated in adults.

Widespread herbivory cost in tropical nitrogen-fixing tree species
Nature, 2022Recent observations suggest that the large carbon sink in mature and recovering forests may be strongly limited by nitrogen1-3. Nitrogen-fixing trees (fixers) in symbiosis with bacteria provide the main natural source of new nitrogen to tropical forests3,4.

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.

MICROPROPAGATION OF TROPICAL TREE SPECIES
Acta Horticulturae, 2013Tree species are important in tropical regions as a source of timber, nutrition, medicine, fuel, income and livestock food. Many vegetable species are not adapted to production in tropical climates, further highlighting the importance of tropical fruit species in these regions.

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).
