Miocene Diversification in the Savannahs Precedes Tetraploid Rainforest Radiation in the African Tree Genus Afzelia (Detarioideae, Fabaceae)

open access: yesFrontiers in Plant Science, 2020
The dating of diversification events, including transitions between biomes, is key to elucidate the processes that underlie the assembly and evolution of tropical biodiversity.

In situ measurements of isoprene and monoterpenes within a south-east Asian tropical rainforest [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
Biogenic volatile organic compounds (BVOCs) emitted from tropical rainforests comprise a substantial fraction of global atmospheric VOC emissions, however there are only relatively limited measurements of these species in tropical rainforest regions.

Nutrition of tree species in tropical dry forest and rainforest environments

open access: yesRevista Ceres, 2020
Knowledge of the nutritional efficiency of species can help revegetation of forest areas, guiding the use of species that best adapt to environmental humidity, altitude and diversity.

Flux estimates of isoprene, methanol and acetone from airborne PTR-MS measurements over the tropical rainforest during the GABRIEL 2005 campaign [PDF]

open access: yes, 2009
Tropical forests are a strong source of biogenic volatile organic compounds (BVOCs) to the atmosphere which can potentially impact the atmospheric oxidation capacity. Here we present airborne and ground-based BVOC measurements representative for the long

Contrasting spatial variations between above and below-ground net primary productivity in global grasslands

open access: yesEcological Indicators
Grassland net primary productivity (NPP) plays a crucial role in global terrestrial carbon cycle and carbon balance. However, the spatial pattern and influencing factors of NPP and its components, especially the belowground net primary productivity (BNPP)

Landscape patterns in rainforest phylogenetic signal: isolated islands of refugia or structured continental distributions? [PDF]

open access: yesPLoS ONE, 2013

Height-diameter allometry of tropical forest trees [PDF]

open access: yes, 2010
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.

Topsoil Carbon Spatial Patterns and Successional Shifts in Dominant Controls in Tropical Forests on Hainan Island

open access: yesLand
Soil organic carbon (SOC) is a key component of terrestrial carbon stocks, yet its spatial variability, recovery potential, and dominant controls across tropical forest succession remain insufficiently quantified.

Climatic controls on vegetation trends and variability in Southeast Asia over the recent two decades

open access: yesEnvironmental Advances
Although the spatiotemporal patterns of vegetation productivity in tropical forests have been widely studied, the differences between long-term trends and interannual variability and their respective driving factors remain poorly understood.

Hysteresis of tropical forests in the 21st century

open access: yesNature Communications, 2020
Tropical rainforests partly create their own climatic conditions by promoting precipitation, therefore rainforest losses may trigger dramatic shifts.
