The forest–savannah transition is the most widespread ecotone in tropical areas, separating
two of the most productive terrestrial ecosystems. Here, we review current understanding of …

Ancient tropical grassy biomes are often misrecognized as severely degraded forests. I trace
this confusion to several factors, with roots in the nineteenth century, including …

Several large-scale drivers of both anthropogenic and natural environmental changes are
interacting nonlinearly in the transition zone between eastern Amazonia and the adjacent …

Aboveground tropical tree biomass and carbon storage estimates commonly ignore tree
height (H). We estimate the effect of incorporating H on tropics-wide forest biomass …

Understanding the nature and extent of ecosystem boundaries has important implications for
the management and conservation of biodiversity. However, characterizing and establishing …

The role played by river networks in regional and global carbon (C) budgets is receiving
increasing attention. Despite the potential of radiocarbon measurements (Δ14C) to elucidate …

Remote sensing (RS) studies aiming at mapping forest biomass typically rely on ground-
based estimates of biomass for calibration or validation. Whatever the biophysical variable …

The idea that tropical forest and savanna are alternative states is crucial to how we manage
these biomes and predict their future under global change. Large-scale empirical evidence …

Background: The zone of transition (ZOT) between the Cerrado and the Amazon forest in
southern Amazonia represents a unique and rapidly shrinking area due to land-use change …

Biomes of the world have long been assumed to be determined by climate. Major disparities,
where open low biomass systems occurred in the same climate zone as closed forests have …
