A Recount of Tropical Tree Species

Science, 2010
If aliens visited earth, perhaps they would wonder how many distinct life forms our planet has. With their advanced intellect and technology, they might well have the answer. It is clear from R. M. May's Perspective “Tropical arthropod species, more or less?” (2 July, p. [41][1]) that we do not.

Seedling Traits Determine Drought Tolerance of Tropical Tree Species

Biotropica, 2008
ABSTRACTWater 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

CpDNA-based species identification and phylogeography: application to African tropical tree species. [PDF]

Molecular ecology, 2010
Despite the importance of the African tropical rainforests as a hotspot of biodiversity, their history and the processes that have structured their biodiversity are understood poorly. With respect to past demographic processes, new insights can be gained through characterizing the distribution of genetic diversity.

Recruitment in Tropical Tree Species: Revealing Complex Spatial Patterns

The American Naturalist, 2009
Seed dispersal should leave a signature on the spatial distribution of recruits that can be quantified using sophisticated techniques of spatial pattern analysis. Here we study spatial patterns of five frugivore-dispersed tropical tree species at the Barro Colorado Island forest, Panama, to describe detailed properties of the spatial patterns of ...

Allometric equations for four valuable tropical tree species

Forest Ecology and Management, 2006
Four tree species were harvested periodically over a 13-year period from plantations in the humid lowlands of Costa Rica: Cedrela odorata, Cordia alliodora, Hyeronima alchorneoides, and Euterpe oleracea. The soil was a well-drained, volcanic alluvium, and high fertility coupled with 4 m of annual rainfall and high temperatures led to rapid growth rates;

Carbonisation of Five Short Rotation Tropical Tree Species

1997
Five fast growing tree species: Acacia mangium, Cassia nodosa, Gliricidia sepium, Gmelina arborea and Leucaena leucocephala were converted to charcoal by pyrolytic process. Charcoal briquettes were prepared from charcoal fines and carbonized wood twigs. The charcoal yield and the combustion related properties of the fuelwood and charcoal, viz: moisture
