Environmental correlates of tree biomass, basal area, wood specific gravity and stem density gradients in Borneo's tropical forestsNARA Subscribed
Aim Tropical forests have been recognized as important global carbon sinks and sources. However, many uncertainties about the spatial distribution of live tree above‐ground biomass (AGB) remain, mostly due to limited availability of AGB field data. Recent studies in the Amazon have already shown the importance of large sample size for accurate AGB gradient analysis. Here we use a large stem density, basal area, community wood...
In the wake of widespread loss of old‐growth forests throughout the tropics, secondary forests will likely play a growing role in the conservation of forest biodiversity. We considered a complex hierarchy of factors that interact in space and time to determine the conservation potential of tropical secondary forests. Beyond the characteristics of local forest patches, spatial and temporal landscape dynamics influence the estab...
Evaluating the Success of Conservation Actions in Safeguarding Tropical Forest BiodiversityNARA Subscribed
We reviewed the evidence on the extent and efficacy of conservation of tropical forest biodiversity for each of the classes of conservation action defined by the new International Union for Conservation of Nature (IUCN) classification. Protected areas are the most tested conservation approach, and a number of studies show they are generally effective in slowing deforestation. There is some documentation of the extent of sustai...
The intermediate disturbance hypothesis applies to tropical forests, but disturbance contributes little to tree diversityNARA Subscribed
The intermediate disturbance hypothesis (IDH) predicts local species diversity to be maximal at an intermediate level of disturbance. Developed to explain species maintenance and diversity patterns in species‐rich ecosystems such as tropical forests, tests of IDH in tropical forest remain scarce, small‐scale and contentious. We use an unprecedented large‐scale dataset (2504 one‐hectare plots and 331 567 trees) to examine wheth...
Inventories of tree species are often conducted to guide conservation efforts in tropical forests. Such surveys are time consuming, demanding of expertise, and expensive to perform and interpret. Approaches to make survey efforts simpler or more effective would be valuable. In particular, it would be good to be able to easily identify areas of old‐growth forest. The average density of the wood of a tree species is closely link...
