Eco-evolutionary priority and the assembly of the New Zealand flora.

ABSTRACT: Eco-evolutionary priority effects, in which early arriving taxa pre-empt environmental niches and evolve to exclude or marginalise later arriving taxa, have been claimed to have influenced current vegetation communities in New Zealand. We here critically assess this claim. An examination of the entire New Zealand conifer and angiosperm flora shows that early arriving lineages do not have more species than later arriving lineages, and do not dominate regional species pools. A nationwide forest plot data set shows no influence of lineage age on tree dominance. Woody species with wide latitudinal ranges tend to be older, but plant height and biotically dispersed fruit exert a stronger influence. Range extent is not influenced by lineage age in the alpine zone. The New Zealand studies on which
