Gamma diversity itself is determined by the mean species diversity in the region's ecosystems (alpha diversity) and the differentiation among those ecosystems (beta diversity). (Whittaker, 1972). Explanation: Alpha diversity refers to the average species diversity in a habitat or specific area.Alpha diversity is a local measure.Beta diversity refers to the ratio between local or alpha diversity and regional diversity.This is the diversity of species between two habitats or regions. a. gamma b. beta c. alpha d. delta. According to Whittaker (1972), gamma diversity is the richness in species of a range of habitats in a geographic area (e.g.,a landscape, an island) and it is consequent on the alpha diversity of the individual communities and the range of differentiation or beta diversity among them.
