Analysing the dynamics of land use in the context of current conservation policies and land tenure in the Cerrado – MATOPIBA region (Brazil).
The side effect of the expansion of agricultural activities in the Brazilian Cerrado resulted in a loss of its native vegetation, biodiversity decline, and increasing greenhouse gas emissions. Recent expansion has mainly occurred in the northern Cerrado, a region known as MATOPIBA, which is the late...

Índice de vulnerabilidade socioambiental na área da gleba “c” da Universidade Federal do Pará, no município de Belé.
No início do século XX, a urbanização e ocupação de espaços privilegiados em detrimento de espaços de baixada e próximos a várzea. As baixadas foram ocupadas por uma população, em sua maioria, com carências socioeconômicas, formando-se conjuntos de habitações suscetíveis à alagamen...

Relationship between biomass burning emissions and deforestation in Amazonia over the last two decades.
With deforestation and associated fires ongoing at high rates, and amidst urgent need to preserve Amazonia, improving the understanding of biomass burning emissions drivers is essential. The use of orbital remote sensing data enables the estimate of both biomass burning emissions and deforestation. ...

Assessing changes in the atmospheric water budget as drivers for precipitation change over two CORDEX-CORE domains.
This study evaluates the projected changes in the atmospheric water budget and precipitation under the RCP8.5 scenario over two CORDEX-CORE domains: South America (SAM) and Europe (EUR). An ensemble of five twenty-first century projections with the Regional Climate Model version 4 (RegCM4) and their...

Conidiation under illumination enhances conidial tolerance of insect-pathogenic fungi to environmental stresses.
Light is an important signal for fungi in the environment and induces many genes with roles in stress and virulence responses. Conidia of the entomopathogenic fungi Aschersonia aleyrodis, Beauveria bassiana, Cordyceps fumosorosea, Lecanicillium aphanocladii, Metarhizium anisopliae, Metarhizium brunn...

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...
