A Zonal‐Meridional Projection Method for Quantifying Global Land‐Ocean Moisture Transport
International Journal of Climatology, EarlyView.We present a physically consistent and computationally efficient method to quantify global coastal moisture transport by projecting vertically integrated moisture flux onto signed land–ocean boundary segments. The signed projection naturally distinguishes ocean‐to‐land inflow and land‐to‐ocean outflow without explicit directional classification ...

Precipitation recycling in the Amazon basin [PDF]
Quarterly Journal of the Royal Meteorological Society, 1994 AbstractPrecipitation recycling is the contribution of evaporation within a region to precipitation in that same region. The recycling rate is a diagnostic measure of the potential for interactions between land surface hydrology and regional climate. In this paper we present a model for describing the seasonal and spatial variability of the recycling ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Cocoa (Theobroma cacao L.) from the Brazilian Amazon plays an important role in national production. While most cocoa is cultivated in upland systems, floodplain ecosystems represent a traditional and distinct production environment that may influence bean composition and quality.

Land Degradation &Development, EarlyView.ABSTRACT Aridification in Semiarid regions is a recurring theme in Intergovernmental Panel on Climate Change (IPCC) reports and has been documented in Northeastern Brazil. This study analyzes the spatiotemporal dynamics of aridification in the Lower São Francisco River “Citizenship Territory” (Sergipe and Alagoas) at a fine spatial resolution (~1 km ...

Historical shifts in Brazilian P. falciparum population structure and drug resistance alleles. [PDF]
PLoS ONE, 2013 Previous work suggests that Brazilian Plasmodium falciparum has limited genetic diversity and a history of bottlenecks, multiple reintroductions due to human migration, and clonal expansions. We hypothesized that Brazilian P.

Primary modes of tree mortality in southwestern Amazon forests
Trees, Forests and People, 2022 Tree mortality rates and the modes of tree death have recently been extensively investigated in the Amazon. However, efforts to describe these processes have not been well distributed across the basin.

A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil
Nordic Journal of Botany, EarlyView.Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat
People and Nature, EarlyView.Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.
