Abstract:
... The palm Euterpe oleracea Martius (açai) has been acclaimed to have a wide range of health-promoting and therapeutic benefits due to its reportedly high levels of antioxidants. Açai has a history of use as a medicinal plant and as a staple food in many parts of Brazil. Traditionally, it has been used to treat fevers, skin complications, digestive disorders and parasitic infections. Açai has also b ...

Abstract:
... Limnoperna fortunei (Bivalvia, Mytilidae), a freshwater bivalve native to Southern Asia, has been an invasive species in South America since 1991. It spread upstream in the La Plata basin reaching the Paraguay River in the vicinity of the Pantanal wetland, Brazil, around 1998. The role of abiotic factors in controlling establishment and abundance of this species is not well known, making projectio ...

Mangrove forests are important sinks of atmospheric carbon, and the internal deposits and fluxes of organic matter can reflect how these ecosystems respond to disturbances and environmental changes.
