Legacy of Amazonian Dark Earth soils on forest structure and species composition

Global Ecology and Biogeography, Volume 29, Issue 9, Page 1458-1473, September 2020., 2020
Abstract Aim Amazonian forests predominantly grow on highly weathered and nutrient poor soils. Anthropogenically enriched Amazonian Dark Earths (ADE), traditionally known as Terra Preta de Índio, were formed by pre‐Columbian populations. ADE soils are characterized by increased fertility and have continued to be exploited following European ...

Desertificação: contextualização e sensoriamento remoto

Estudos Geológicos, 2014
A desertificação pode ser conceituada como o processo de degradação das terras das regiões áridas, semiáridas e sub-úmidas secas, resultante de diferentes fatores, entre eles as variações climáticas e as atividades humanas. No Brasil, a ocorrência dos processos de desertificação é observada, especialmente, em ambiente de caatinga do sertão nordestino ...

Correção Atmosférica em Sensoriamento Remoto: Uma Revisão

Revista Brasileira de Geografia Física, 2020
A correção atmosférica é um procedimento necessário em estudos de sensoriamento remoto com foco nas propriedades físicas, químicas e biológicas de alvos. Em abordagens multitemporais e/ou multisensor, a correção atmosférica é fundamental para a obtenção de medidas de reflectância de superfície representativas das características espectrais dos alvos ...

Environmental Controls on the Riverine Export of Dissolved Black Carbon

Global Biogeochemical Cycles, Volume 33, Issue 7, Page 849-874, July 2019., 2019
Abstract Each year, tropical rivers export a dissolved organic carbon (DOC) flux to the global oceans that is equivalent to ~4% of the global land sink for atmospheric CO2. Among the most refractory fractions of terrigenous DOC is dissolved black carbon (DBC), which constitutes ~10% of the total DOC flux and derives from the charcoal and soot (aerosol)

SpiderATLAS: A Database of Spider Traits and Distributions in the Brazilian Atlantic Forest

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim Biodiversity shortfalls related to limited knowledge about geographic distribution (Wallacean) and species traits (Raunkiæran) are extremely common in many animal groups and perhaps more evident in invertebrate groups such as spiders. This lack of knowledge could present challenges for researchers investigating the response and effects of ...

Towards a global understanding of tree mortality [PDF]

new phytologist
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.
