- | Divide the chapter into | + | Divide the chapter into alpha+gamma diversity section and beta diversity section. One option - use Jurasinsky et al 2009 schema and talk about inventory, differentiation and proportional diversity (inventory = alpha and gamma, differentiation = based on dissimilarity measures, incl. variation within compositional matrix and length of DCA axis; proportional - gamma vs alpha, additive vs multiplicative, |
+ | Other option is to divide the whole topic into several chapters: | ||
+ | - alpha diversity (inventory diversity) | ||
+ | - includes species richness, Shannon entropy, Simpson concentration index, Hill's numbers, effective number of species | ||
+ | - rarefaction and accumulation curves, estimates of unseen species | ||
+ | - beta diversity | ||
+ | - differentiation diversity - Legendre' | ||
+ | - proportional diversity - Whittaker' | ||
