Palaeobotanical experiences of plant diversity in deep time. 2: How to measure and analyse past plant biodiversity

“…Some of these problems can be resolved (e.g., by making repeated analyses and using the ordination with the lowest stress value). Some authors now use NMDS where DCA may previously have been used in palaeoecological (Willard 1993;DiMichele et al, 1991DiMichele et al, , 2017bPryor 1996;Bashforth et al 2011;Barreda et al 2012;Sala-Pérez et al 2020) and floristic studies (Cúneo 1996;Barbacka et al 2014). However, when DCA and NMDS have been compared, they have produced broadly similar ordinations (e.g., DiMichele et al 1991) and so, given the advantages of DCA (notably that it shows which taxa are exerting the greatest influence on the ordination) it would seem to be preferable.…”
