Question #46039

Analyze the following statements regarding the Species-Area Relationship ($S = CA^z$) and the impacts of the 'Evil Quartet':

I. For most taxonomic groups within a contiguous region, the regression coefficient (Z-value) lies between 0.1 and 0.2. II. When analyzing very large areas like entire continents, the slope of the line becomes much steeper, with Z-values ranging from 0.6 to 1.2. III. If a contiguous forest is subjected to severe anthropogenic fragmentation, the Z-value for the newly isolated patches remains constant at 0.1 to 0.2 because they represent small regional areas. IV. Habitat fragmentation forces a steeper regression slope (higher Z-value) for isolated patches because the restricted area and edge effects lead to an exponential, rather than linear, decline in biodiversity.
