Estimating rates and patterns of diversification with incomplete sampling: a case study in the rosids.

ABSTRACT:

Premise

Recent advances in generating large-scale phylogenies enable broad-scale estimation of species diversification. These now common approaches typically are characterized by (1) incomplete species coverage without explicit sampling methodologies and/or (2) sparse backbone representation, and usually rely on presumed phylogenetic placements to account for species without molecular data. We used empirical examples to examine the effects of incomplete sampling on diversification estimation and provide constructive suggestions to ecologists and evolutionary biologists based on those results.

Methods

We used a supermatrix for rosids and one well-sampled subclade (Cucurbitaceae) as empirical case studies. We compared results using these large phylogenies with those based on a
