The distribution of diversity: challenges and applications

Phylogenetic difference . Some ecologists argue that species that are more phylogenetically distinct contribute more to the total genetic and morphological diversity and so should be given priority
for protection (Weitzman, 1993 ; Faith et al ., 2004b ; Faith, 2009 ; and see Box 7.1). It has been suggested that a good way to generate a plan using this criterion is to use higher taxa (i.e. genus, family)
instead of species in the planning process (Mooers, 2007 ).
Figure B6.1d The marine iguana ( Amblyrhynchus cristatus ) is found only on the Galapagos Islands. Uniquely among
modern lizards, this animal lives and forages in the sea. It is threatened by predation by exotic species. Photograph:

distinct member of a two - species family inhabiting northern South America. Photograph: James Watson.
