Fire feedbacks facilitate invasion of pine savannas by Brazilian pepper (Schinus terebinthifolius)
New Phytologist, 2009* Fire disturbance can mediate the invasion of ecological communities by nonnative species. Nonnative plants that modify existing fire regimes may initiate a positive feedback that can facilitate their continued invasion. Fire-sensitive plants may successfully invade pyrogenic landscapes if they can inhibit fire in the landscape.

Araucaria angustifolia Bert. (O. Ktze), also known as the “Brazilian pine”, is native to the South of Brazil. This species has a long reproductive cycle, taking about 29–34 months. Its cones begin to develop in early January and remain dormant from March to July.

Genetic Conservation of Brazilian Pine (Araucaria angustifolia) Through Traditional Land Use
Economic Botany, 2018Traditional land use may play a key role in conserving and promoting ecosystem integrity. However, little is known about conserving genetic diversity in such traditional management systems. The Brazilian pine (Araucaria angustifolia) is an important element of traditionally managed landscapes in southern Brazil but is currently considered at risk of ...

Can native vegetation recover after slash pine cultivation in the Brazilian Savanna?
Forest Ecology and Management, 2011Abstract There is a widespread view that forest plantations with exotic species are green deserts, unable to sustain biodiversity. Few studies have demonstrated, however, that planted stands of exotic trees have a greater negative effect on the plant diversity of savanna vegetation.

The development of polyembryony is a common reproductive strategy in conifers. Multiple embryos are observed during early seed developmental stages. However, upon seed maturation, only the dominant embryo survives, with few exceptions. Although programmed cell death has been reported as the major mechanism responsible for elimination of subordinate ...

Araucaria angustifolia is the only native conifer of economic importance in the Brazilian Atlantic Rainforest. Due to a clear-cutting form of exploitation this species has received the status of vulnerable. The aim of this work was to investigate and characterize changes in protein expression profile during seed development of this endangered species ...
