Additivity properties in metapopulation models: implications for the assessment of marine reserves

摘要: Abstract Marine reserves increase both aggregate (system-wide) catches and population levels when the dispersal benefits from reserve are greater than opportunity cost of closing area to fishing. Although general nature this condition is clear, how underlying bioeconomic drivers interact determine outcome not. In paper, we develop a class spatially explicit models that enable us explore different assumptions regarding connectivity can lead assessments marine reserves. The analysis also illustrates incorporation space into resource exploitation raises fundamental questions about relationship biological production in each patch. We show with supraadditivity property—system-wide sum patch no dispersal—are more likely predict outweigh costs.
