Soluble iron nutrients in Saharan dust over the central Amazon rainforest [PDF]

Atmospheric Chemistry and Physics, 2017
The intercontinental transport of aerosols from the Sahara desert plays a significant role in nutrient cycles in the Amazon rainforest, since it carries many types of minerals to these otherwise low-fertility lands.

Forest–Fruticulture Conversion Alters Soil Traits and Soil Organic Matter Compartments

Plants, 2022
Fruticulture in the Amazonian Rainforest is one of the main causes of deforestation, biodiversity loss, and soil erosion. Fruticulture plays a key role in the soil traits and soil organic matter (SOM) compartments by altering the soil ecosystem.

Humans and platyrrhines share a pattern of articular variance

The Anatomical Record, EarlyView.
Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Cerrado Conservation is Essential to Protect the Amazon Rainforest [PDF]

AMBIO, 2010
Despite widespread deforestation the forests of Amazonia still cover more than 5 million km2 and may host up to a quarter of the world’s terrestrial species (Dirzo and Raven 2003)—many of which are still undocumented. Conservation of these forests is important, not just for the biodiversity they contain, but also for the vital ecosystem services they ...

First reports on the relationship between the eggshell and bone mineralization in Rhinoclemmys punctularia punctularia embryos

The Anatomical Record, EarlyView.
Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...

Fungal spores as a source of sodium salt particles in the Amazon basin

Nature Communications, 2018
Salt particles in the Amazon basin are typically attributed to marine aerosols transported from the Atlantic Ocean. Here the authors show the potential importance of fungal spores as a source of sodium-salt particles in the Amazon rainforest.
