Open AccessForest fragmentation impacts the seasonality of Amazonian evergreen canopies
Predictions of the magnitude and timing of leaf phenology in Amazonian forests remain highly controversial. Here, we use terrestrial LiDAR surveys every two weeks spanning wet and dry seasons in Central Amazon...

Upscaling Forest Biomass from Field to Satellite Measurements: Sources of Errors and Ways to Reduce Them
Forest biomass monitoring is at the core of the research agenda due to the critical importance of forest dynamics in the carbon cycle. However, forest biomass is never directly measured; thus, upscaling it fro...

Open AccessDisturbance Regimes Drive The Diversity of Regional Floristic Pools Across Guianan Rainforest Landscapes
Disturbances control rainforest dynamics, and, according to the intermediate disturbance hypothesis (IDH), disturbance regime is a key driver of local diversity. Variations in disturbance regimes and their con...

Quantifying micro-environmental variation in tropical rainforest understory at landscape scale by combining airborne LiDAR scanning and a sensor network
We combined aerial LiDAR and ground sensors to map the spatial variation in micro-environmental variables of the tropical forest understory. We show that these metrics depend on forest type and...

Contrasted allometries between stem diameter, crown area, and tree height in five tropical biogeographic areas
Across five biogeographic areas, DBH-CA allometry was characterized by inter-site homogeneity and intra-site heterogeneity, whereas the reverse was observed for DBH-H allometry.

Revisiting a universal airborne light detection and ranging approach for tropical forest carbon map**: scaling-up from tree to stand to landscape
Airborne laser scanning provides continuous coverage map** of forest canopy height and thereby is a powerful tool to scale-up above-ground biomass (AGB) estimates from stand to landscape. A critical first st...

Crown allometries are less responsive than stem allometry to tree size and habitat variations in an Indian monsoon forest
While theoretical allometric models postulate universal scaling exponents, empirical relationships between tree dimensions show marked variability that reflects changes in the biomass allocation pattern. As gr...

Tree shape plasticity in relation to crown exposure
Trees outside closed forest stands differ in the relation between stem diameter, height and crown volume from trees that grew with neighbours close by. Whether this plasticity in tree shape varies between spec...

The relative importance of dispersal limitation and habitat preference in sha** spatial distribution of saplings in a tropical moist forest: a case study along a combination of hydromorphic and canopy disturbance gradients
Various processes contribute to sha** the local assemblage of species in hyperdiverse tropical forest. The relative contribution of environmental factors and dispersal limitation in determining the spatial d...

A Component-Based Framework for Simulating Agricultural Production and Externalities
Although existing simulation tools can be used to study the impact of agricultural management on production activities in specific environments, they suffer from several limitations. They are largely specializ...

Open AccessPlant and bird diversity in rubber agroforests in the lowlands of Sumatra, Indonesia
Plant and bird diversity in the Indonesian jungle rubber agroforestry system was compared to that in primary forest and rubber plantations by integrating new and existing data from a lowland rain forest area i...
