Despite two orders of magnitude less sampling effort, eDNA detected 44% more species than UVC or BRUVS; with only 22 samples, 13 shark species were detected, reducing … WebBoth dark diversity and beta-diversity are derived from common local richness or alpha diversity. Beta-diversity is determined by gamma-diversity whereas dark diversity is derived from the species pool. Gamma-diversity is basically just the sum or an extrap olation of the number of species encountered locally, that is, directly related to alpha
