Plant phosphorus-use and -acquisition strategies in Amazonia.

New Phytologist, 2022
In the tropical rainforest of Amazonia, phosphorus (P) is one of the main nutrients controlling forest dynamics, but its effects on the future of the forest biomass carbon (C) storage under elevated atmospheric CO2 concentrations remain uncertain.

Early Holocene crop cultivation and landscape modification in SW Amazonia

Nature, 2020
The onset of plant cultivation is one of the most important cultural transitions in human history 1 – 4 . Southwestern Amazonia has previously been proposed as an early centre of plant domestication, on the basis of molecular markers that show genetic ...

Fragmentation-Driven Divergent Trends in Burned Area in Amazonia and Cerrado

Frontiers in Forests and Global Change, 2022
The two major Brazilian biomes, the Amazonia and the Cerrado (savanna), are increasingly exposed to fires. The Amazonian Forest is a fire sensitive ecosystem where fires are a typically rare disturbance while the Cerrado is naturally fire-dependent ...

Widespread reforestation before European influence on Amazonia

Science, 2021
Pre-Columbian reforestation in Amazonia An early 17th-century temporary reduction in global atmospheric carbon dioxide (CO2) levels has now been attributed to reforestation in Amazonia after the catastrophic loss of life of the indigenous population ...

Systematics and biogeography of the Boana albopunctata species group (Anura, Hylidae), with the description of two new species from Amazonia

Systematics and Biodiversity, 2021
The outstanding species richness of Amazonia has fascinated biologists for centuries. However, the records of actual numbers and distribution of species forming its ecosystems are so incomplete that the understanding of the historical causes and regional

Sensory ecologies, plant-persons and multinatural landscapes in Amazonia

Botany, 2021
Seeking to generate a deeper methodological and theoretical dialogue between botanical science and anthropology, this paper summarizes interdisciplinary approaches to human-plant interactions we have described as “sensory ecology” and “phytoethnography,”

Competition influences tree growth, but not mortality, across environmental gradients in Amazonia and tropical Africa

Ecology, 2020
Competition among trees is an important driver of community structure and dynamics in tropical forests. Neighboring trees may impact an individual tree’s growth rate and probability of mortality, but large‐scale geographic and environmental variation in ...
