Big‐sized trees overrule remaining trees' attributes and species richness as determinants of aboveground biomass in tropical forests

Global Change Biology, 2019
Large‐diameter, tall‐stature, and big‐crown trees are the main stand structures of forests, generally contributing a large fraction of aboveground biomass, and hence play an important role in climate change mitigation strategies.

Towards quantifying tropical tree species richness in tropical forests

International Journal of Remote Sensing, 2009
This 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 ...

Comparison of temperate and tropical freshwater species’ acute sensitivities to chemicals: An update

Integrated Environmental Assessment and Management, 2019
Toxicity data for tropical species are often lacking for deriving water quality guidelines (WQGs) and for conducting ecological risk assessment (ERA). To protect and safeguard valuable natural resources and important biodiversity in tropical freshwater ...

Beetle Species Responses to Tropical Forest Fragmentation

Ecological Monographs, 1998
(Uploaded by Plazi for the Bat Literature Project) The effects of forest fragmentation on beetle species composition were investigated in an experimentally fragmented tropical forest landscape in Central Amazonia. Leaf-litter beetles were sampled at seven distances from the forest edge (0–420 m) along forest edge-to-interior transects in two 100-ha ...

The evolution of a tropical biodiversity hotspot

Science, 2020
Diversity does not drive speciation The role of the environment in the origin of new species has long been debated. Harvey et al. examined the evolutionary history and species diversity of suboscine birds in the tropics (see the Perspective by Morlon ...

Tropical species of Agaricus

2018
Agaricus is a large genus of mushrooms including species of nutritional and medicinal interest. With research programs developed over the last decade, a larger diversity of Agaricus came to light. The present review focuses on tropical species of Agaricus and their classification, including a discussion of the definition of tropical species, a brief ...

Micropropagation of Tropical Woody Species

2003
During the last thirty years plant micropropagation has been one of the most significant contributions of biotechnology to the horticultural industry (Giles and Friesen, 1994). The possibility of mass propagation of elite, endangered, or difficult-to-propagate genotypes, in relatively small areas and time period, is the most important characteristic of

Ecology and genetics of tropical rhizobia species

Biotechnology Advances, 1985
Biological nitrogen fixation (BNF) technology with special reference to Rhizobium-legume symbiosis is growing very rapidly with the hope of combatting world hunger by producing cheaper protein for animal and human consumption in the Third World. One can see rapid progress made in the biochemistry and molecular biology of symbiotic nitrogen fixation in ...

Hurricane Disturbance and Tropical Tree Species Diversity

Science, 2000
The 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 ...
