| Abstract | netic relatedness in species assemblages (see below). Here, we utilize a similar approach in North American angiosperm trees and fi nd that strong relationships between climate and richness are not an alternative explanation for richness but that these climate – richness relationships must themselves be explained by the ecological, evolutionary, and biogeographic processes of speciation, extinction, and dispersal (see also Ricklefs 2004, 2006a, Wiens and Donoghue 2004, Wiens 2011, Kozak and Wiens 2012). Th ere are two general explanations for both climate – richness relationships and richness patterns in general, which both integrate ecology and evolution (reviewed by Wiens 2011): 1) higher net diversifi cation rates in certain climatic regimes, regions, or habitats, and 2) greater time for speciation to build up richness in certain climatic regimes, regions, or habitats relative to others. Under the fi rst explanation, certain ecological conditions promote a higher net rate of diversifi cation, where diversifi cation is the balance of speciation and extinction over time (diversifi cation speciation – extinction). For example, many hypotheses about the latitudinal diversity gradient are ultimately based on how ecological conditions in tropical regions promote Ecography 37: 001–010, 2014 doi: 10.1111/ecog.00952 © 2014 Th e Authors.
