Slope of Species-Area Relationship — NEET Biology

Which of the following statements are NOT correct regarding the patterns of biodiversity and the species-area relationship? S1: Tropical regions, located between 23.5° N and 23.5° S, generally exhibit higher species diversity compared to temperate or polar areas. S2: One key reason for the high diversity in tropical latitudes is their history of frequent glaciations, which accelerated evolutionary diversification. S3: Stable and predictable tropical environments favour niche generalisation, allowing a wider range of species to coexist without intense competition. S4: The Amazonian rainforest is renowned for its immense biodiversity, including over 40,000 species of plants and 1,25,000 species of invertebrates. S5: Alexander von Humboldt observed that species richness increased with explored area, and this relationship is typically a linear function on an arithmetic scale. S6: For frugivorous birds and mammals in tropical forests across different continents, the slope (Z-value) of the species-area regression line is found to be 0.15.
