Shannon richness
Webbwas analyzed using Simpson’s diversity indices, Shannon–Weiner index and Evenness.The fungal isolates were screened for the production of extracellular enzymes, of which 29% were positive for amylase, 28% for cellulase, 18% for pectinase and 40% for asparaginase activity. None of the endophytic isolates depicted laccase activity. WebbShannon's index of diversity H' is derived from information theory, originally in the context of information in telephone systems (Shannon, 1948). It combines both evenness and …
