Bridging Species Richness and True Diversity: A Quantitative and Ratio Analysis Approach from Indian Biodiversity Studies

The dataset is used in proposed new metrics linking species richness (N​0) and true diversity, calculated as the first-order Hill Number (N1​). The metrics include Diversity Delta (N0​−N1​), True Diversity-to-Species Richness Ratio (N1​/N0​), and Species Richness-to-True Diversity Multiple (N0​/N1​). The dataset is based on ecological work done in India over last 25 years.
