Integration of qualitative and quantitative methods for land-use-change modeling in a deforestation frontier. [PDF]
Abstract Development and implementation of effective protected area management to reduce deforestation depend in part on identifying factors contributing to forest loss and areas at risk of conversion, but standard land‐use‐change modeling may not fully capture contextual factors that are not easily quantified.

From Sovereignty to Guardianship in Ecoregions
ABSTRACT Recent scientific studies suggest that the destabilisation of the earth's climate and biodiversity loss are not separate, but interdependent phenomena. In this context, some have proposed the creation of a ‘Global Safety Net’ of ecoregions that should be preserved to stop further biodiversity loss, preventing at the same time the growth of CO2

Deforestation and habitat fragmentation are known as the chief drivers of biodiversity loss. Habitat fragmentation in the Brazilian Amazon was found to affect the weight of birds that remained in isolated areas. Our results provide a novel analysis into how avian body mass responds to habitat fragmentation.

REDD+ and forest protection on indigenous lands in the Amazon
Abstract Reducing emissions from deforestation and forest degradation (REDD+) was introduced by the United Nations Framework Convention on Climate Change (UNFCCC) as a mechanism to reverse the loss of forests and carbon stocks in developing countries. REDD+ operates on the basis of performance‐based payments.
