A “Dirty”‘ Footprint: Macroinvertebrate diversity in Amazonian Anthropic Soils.
Amazonian rainforests, once thought to be pristine wilderness, are increasingly known to have been widely inhabited, modified, and managed prior to European arrival, by human populations with diverse cultural backgrounds. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Bas...

Rural landscapes and agrarian spaces under soybean expansion dynamics: a case study of the Santarém region, Brazilian Amazonia
Following the boom of soybean production from 2000 to 2006 in the Santarém region of the Brazilian Amazon, the mechanized agricultural area remained stable, unlike other regions. Deforestation was controlled, but this initial expansion led to the restructuring of the agrarian space in the region. G...

Quaternary sigmodontines (Mammalia, Rodentia) from Serra da Bodoquena, Mato Grosso do Sul, Brazil
Sigmodontine rodents are extremely diversified in the Neotropics but their fossil record remains generally poorly known, especially in Brazil. Here, we examine the assemblage of sigmodontines from the limestone cave Nossa Senhora Aparecida (21°5ʹ27.89”S 56°34ʹ28.77”W), located in Serra da Bo...

Improving CLM5.0 Biomass and carbon exchange across the western United States Using a data assimilation system.
The Western United States is dominated by natural lands that play a critical role for carbon balance, water quality, and timber reserves. This region is also particularly vulnerable to forest mortality from drought, insect attack, and wildfires, thus requiring constant monitoring to assess ecosystem...

Assessment of extreme rainfall estimates from satellite-based: regional analysis.
Excessive rain may cause several problems for society. Understanding the behaviour of extreme rainfall and quantifying it in an assertive manner is important for whole society. The purpose of this work is to evaluate the ability of satellite precipitation products to detect the extreme rainfall over...

The Brazilian Cerrado is becoming hotter and drier.
The Brazilian Cerrado is a global biodiversity hotspot with notoriously high rates of native vegetation suppression and wildfires over the past three decades. As a result, climate change can already be detected at both local and regional scales. In this study, we used three different approaches base...

Large and increasing methane emissions from eastern Amazonia derived from satellite data, 2010-2018.
We use a global inverse model, satellite data and flask measurements to estimate methane (CH4/ emissions from South America, Brazil and the basin of the Amazon River for the period 2010-2018. We find that emissions from Brazil have risen during this period, most quickly in the eastern Amazon basin, ...

Sensible heat flux assessment in a complex coastal-mountain urban area in the metropolitan area of Rio de Janeiro, Brazil.
Obtaining accurate estimates of surface-atmosphere energy exchanges and improved comprehension of the mechanisms generating turbulent fluxes over non-uniform landscapes are both challenging goals and essential for validating numerical weather forecasting modeling. In this work, a large-aperture scin...

Fungal tolerance to Congo red, a cell wall integrity stress, as a promising indicator of ecological niche.
Differential sensitivities to the cell wall stress caused by Congo red (CR) have been observed in many fungal species. In this study, the tolerances and sensitivities to CR was studied with an assorted collection of fungal species from three phylogenetic classes: Sordariomycetes, Dothideomycetes, an...

Policy and governance dynamics in the water-energy-food-land nexus of biofuels: Proposing a qualitative analysis model.
The production of biofuels is inextricably linked with the water-energy-food-land (WEFL) nexus. Understanding these linkages is necessary to formulate effective policies that can influence positive outcomes and contribute to the realization of long-term economic, environmental, and social goals. The...
