Multifaceted Assessment of Amazonian Tree Diversity Reveals Pervasive Impacts of Human Modification. [PDF]
Amazonian forests impacted by humans have a reduced and different group of tree species than those forests that have never been impacted. The trees present in forests impacted by humans also have different evolutionary histories and functional characteristics.

Past human‐induced ecological legacies as a driver of modern Amazonian resilience
Abstract People have modified landscapes throughout the Holocene (the last c. 11,700 years) by modifying soils, burning forests, cultivating and domesticating plants, and directly and indirectly enriched and depleted plant abundances. These activities also took place in Amazonia, which is the largest contiguous piece of rainforest in the world, and for

Fish on Fire: Shifts in Amazonian fish communities after floodplain forest fires
Amazonian fish communities change after floodplain forest fires. Unburnt forests have diverse fish communities, with a large proportion of unique and small omnivorous species. In contrast, carnivores and detritivores become more common in fire scars and white‐sand savannas formed after forest fires. Less omnivore fish after forest fires can reduce tree

Towards a whole‐system framework for wildfire monitoring using Earth observations
Earth observation data are critical for monitoring fires and their impacts as fire seasons become less predictable. In this manuscript, we draw upon multiple disciplines to present a whole‐system framework for identifying and synthesizing fire monitoring objectives and data needs throughout the life cycle of a fire event.

Activating dark earths: somatosoils and the carbonic loops of Amazonian ecologies
Abstract Inspired by the fertility and climate change‐mitigation properties of the so‐called Amazonian Dark Earths (ADEs), soil science has devised a technoscientific replica, a soil amendment known as biochar, intended to improve agricultural sustainability and carbon storage in the biosphere. Drawing on fieldwork with Afroindigenous horticulturalists,
