WebbLou Jost (2002) argued that to call Shannon and Simpson (or Ginni-Simpson, respectively) indices as diversity is misleading, since diversity should be measured in intuitive units of species, while each of the two indices have different units (Shannon bits and Simpson probability) 4).This problem can be overcome by introducing concept of effective … Webb19 aug. 2024 · Apple pomace (AP) contains biomolecules that induce changes in intestinal fermentation of monogastrics with positive expected health effects.
