Tree species richness of upper Amazonian forests

Landscape Variation in Tree Species Richness in Northern Iran Forests

Mapping landscape variation in tree species richness (SR) is essential to the long term management and conservation of forest ecosystems. The current study examines the prospect of mapping field assessments of SR in a high-elevation, deciduous forest in northern Iran as a function of 16 biophysical variables representative of the area's unique physiography, including topography and coastal plac...

Restinga forests of the Brazilian coast: richness and abundance of tree species on different soils.

The aim of this study was to determine changes in composition, abundance and richness of species along a forest gradient with varying soils and flood regimes. The forests are located on the left bank of the lower Jucu River, in Jacarenema Natural Municipal Park, Espírito Santo. A survey of shrub/tree species was done in 80 plots, 5x25 m, equally distributed among the forests studied. We include...

Megafauna extinction, tree species range reduction, and carbon storage in Amazonian forests

Between 132 000 and 1000 yr bp (and mostly  50 000 yr bp), there was a global loss of large animals, with at least 154 mammal megafauna ( 44 kg body mass) species going extinct (Sandom et al. 2014). A critical and unanswered question is how these extinctions affected ecosystem processes and global ecological trajectories (Doughty 2013). Answering this question is central for understanding pal...

Oxygenated volatiles from Amazonian floodplain tree species

Rapid tree carbon stock recovery in managed Amazonian forests

While around 20% of the Amazonian forest has been cleared for pastures and agriculture, one fourth of the remaining forest is dedicated to wood production. Most of these production forests have been or will be selectively harvested for commercial timber, but recent studies show that even soon after logging, harvested stands retain much of their tree-biomass carbon and biodiversity. Comparing sp...
