RESUMO
Understanding how large-scale bioenergy production can affect biodiversity and ecosystems is important if society is to meet current and future sustainable development goals. A variety of bioenergy production systems have been established within different contexts throughout the Pan American region, with wide-ranging results in terms of documented and projected effects on biodiversity and ecosystems. The Pan American region is home to the majority of commercial bioenergy production and therefore the region offers a broad set of experiences and insights on both conflicts and opportunities for biodiversity and bioenergy. This paper synthesizes lessons learned focusing on experiences in Canada, the United States, and Brazil regarding the conflicts that can arise between bioenergy production and ecological conservation, and benefits that can be derived when bioenergy policies promote planning and more sustainable land-management systems. We propose a research agenda to address priority information gaps that are relevant to biodiversity concerns and related policy challenges in the Pan American region.

A avaliação nutricional dos RNs (recém-nascidos) de baixo peso e muito baixo peso é importante para o acompanhamento do quadro clínico dos mesmos, em especial na identificação daqueles com risco de alterações decorrentes de distúrbios da nutrição intra-uterina. Foi estudado, no período de 22/09 a 01/11/2001 de maneira prospectiva, um grupo de 43 RNs,
