 Plan: Plan:
-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,​ using Hill's numbers for it etc.) 
 +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'​s approach, incl. LCBD, mean of pairwise dissimilarity indices, multisite dissimilarity indices 
 +   - proportional diversity - Whittaker'​s beta, beta based on Hill's numbers, Chao's beta diversity (beta differentiation)
