Most ecological hypotheses about species coexistence hinge on differences, but quantifying trait differences across in diverse communities is often unfeasible. We examined the variation of demographic traits using a global tropical forest data set covering 4500 10 large-scale tree inventories. With hierarchical Bayesian approach, we quantified distribution mortality and growth rates all at each site. This allowed us to test prediction that facilitate richness, as suggested by theory tradeoff...
In Amazonian tropical forests, recent studies have reported increases in aboveground biomass and primary productivity, as well shifts plant species composition favouring fast-growing over slow-growing ones. This pervasive alteration of mature forests was attributed to global environmental change, such an increase atmospheric CO2 concentration, nutrient deposition, temperature, drought frequency, and/or irradiance. We used standardized, repeated measurements 2 million trees ten large (16-52...
An ecological community's species diversity tends to erode through time as a result of stochastic extinction, competitive exclusion, and unstable host-enemy dynamics. This erosion can be prevented over the short term if recruits are highly diverse preferential recruitment rare or, alternatively, survive preferentially, which increases ages individuals increase. Here, we present census data from seven New Old World tropical forest dynamics plots that all show latter pattern. Within local...
Forest structure and species distribution patterns were examined among eight topographically defined habitats for the 205 with stems ≥ 1 cm dbh inhabiting a 25-ha plot in Sinharaja rain forest, Sri Lanka. The steep spurs, less-steep gullies gullies, all at either lower or upper elevations. Mean stem density was significantly greater on spurs than lower, gullies. Stem also higher within each elevation category upper-elevation habitat its corresponding lower-elevation habitat. Basal area...
Abstract. Advances in forest carbon mapping have the potential to greatly reduce uncertainties global budget and facilitate effective emissions mitigation strategies such as REDD+ (Reducing Emissions from Deforestation Forest Degradation). Though broad-scale is based primarily on remote sensing data, accuracy of resulting stock estimates depends critically quality field measurements calibration procedures. The mismatch spatial scales between inventory plots larger pixels current planned...

When Darwin visited the Galapagos archipelago, he observed that, in spite of islands' physical similarity, members species that had dispersed to them recently were beginning diverge from each other. He postulated these divergences must have resulted primarily interactions with sets other also diverged across otherwise similar islands. By extrapolation, if is correct, such complex be driving all ecosystems. However, many current general ecological theories predict distributions ecosystems do...
Abstract Elephants Elephas maximus have declined in range and number the wild Sri Lanka, from c . 12,000 at turn of nineteenth century to 4000 today. While distant past decline elephant numbers was due largely indiscriminate killing by sportsmen trophy hunters, today elephants are being killed primarily because they interfere with agriculture. Human-elephant conflicts increased substantially recent ivory poaching has become a byproduct such conflicts. Elephant tusks been used traditionally...
