Tropical rainforests: Diversity begets diversity [PDF]

open access: yesCurrent Biology, 1997
Tropical rainforests exhibit an extraordinarily high level of biological diversity. A new study shows that the patterns of seedling survival surrounding parent trees are responsible in large part for this amazing diversity.

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.

Drought drives rapid shifts in tropical rainforest soil biogeochemistry and greenhouse gas emissions

open access: yesNature Communications, 2018
Climate change models predict more frequent and severe droughts in the humid tropics. How drought will impact tropical forest carbon and greenhouse gas dynamics is poorly understood. Here we report the effects of the severe 2015 Caribbean drought on soil

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.

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)

Melanism and color saturation of butterfly assemblages: A comparison between a tropical rainforest and a xeric white forest

open access: yesFrontiers in Ecology and Evolution, 2023
The study of butterfly coloration has helped to identify the ecological pressures involved in the evolution of animal coloration. However, almost all studies that addressed this issue have focused on species that inhabit more temperate environments ...

Forest restoration in tropical forests recovers topsoil water retention but does not improve deep soil layers

open access: yesInternational Soil and Water Conservation Research
Tropical primary forests have been rapidly reduced in recent decade owing to slash-and-burn, leading to the formation of tropical secondary forests in different recovery stages.

Interannual and Seasonal Variations in Ecosystem Transpiration and Water Use Efficiency in a Tropical Rainforest

open access: yesForests, 2018
Warmer and drier climates over Amazonia have been predicted for the next century with expected changes in regional water and carbon cycles. We examined the impact of interannual and seasonal variations in climate conditions on ecosystem-level ...
