This chapter elaborates on case-specific methodologies (for use during the pre-release stages of Bt cotton) to support risk assessment of nontarget organisms and biodiversity applied to the Brazil case study: (1) identifying functional categories of biodiversity; (2) listing and prioritizing nontarget species and processes; (3) identifying trophically mediated exposure pathways to transgenic plant and transgene products; (4) identifying possible adverse effect scenarios for trophically mediated and other ecological effects; and (5) testing hypotheses and experimental designs to test causal chains of events associated with specific exposure pathways and adverse effect scenarios. A systematic, scientifically justifiable precautionary approach for dealing with scientific uncertainty is also provided.

Abstract
This chapter elaborates on case-specific methodologies (for use during the pre-release stages of Bt cotton) to support risk assessment of nontarget organisms and biodiversity applied to the Brazil case study: (1) identifying functional categories of biodiversity; (2) listing and prioritizing nontarget species and processes; (3) identifying trophically mediated exposure pathways to transgenic plant and transgene products; (4) identifying possible adverse effect scenarios for trophically mediated and other ecological effects; and (5) testing hypotheses and experimental designs to test causal chains of events associated with specific exposure pathways and adverse effect scenarios. A systematic, scientifically justifiable precautionary approach for dealing with scientific uncertainty is also provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
