             abstract = "Forest fragmentation due to deforestation is one of the major 
                         causes of forest degradation in the Amazon. Biomass collapse near 
                         forest edges, especially within 100 m, alters aboveground biomass 
                         and has potentially important implications for carbon emissions in 
                         the region. This phenomenon is tightly linked to spatial and 
                         temporal dynamics of forest edges in a landscape. However, the 
                         potential biomass loss and carbon emissions from forest edges and 
                         these spatiotemporal changes have never been estimated for actual 
                         landscapes in the Amazon. We conducted a deep temporal analysis of 
                         Rondonia, southwestern Brazilian Amazonia, using six Landsat 
                         path-row scenes covering the 1985-2008 time period to estimate 
                         annual biomass loss and associated carbon emissions within 100 m 
                         of forest edges. Annual edge biomass loss averaged 9.1% of the 
                         biomass loss from deforestation during the study period, whereas 
                         average annual edge-related carbon emissions from biomass loss 
                         were 6.0% of deforestation-derived carbon emissions. However, 
                         because many edges were subsequently deforested during the 24 year 
                         study period, actual unaccounted for edge-related carbon emissions 
                         during the 1985-2008 period, calculated from edges of all ages 
                         extant on the landscape in 2008, amounted to 3.6% of that 
                         attributed to all deforestation-derived carbon fluxes for this 
                         time interval. Biomass loss and carbon emissions are highly 
                         influenced by the extent and age of edge-affected forests. Large 
                         annual contributions of biomass loss and carbon emissions were 
                         found from active deforestation regions with young edges, whereas 
                         regions dominated by older edges had lower biomass loss and carbon 
                         emissions from edges.",
