Abstract
Inferring interfamilial relationships within the eudictot order Ericales has remained one of the more recalctitrant prolems in angiosperms, likely due to to a rapid, ancient radiation. As a result no comprehensive time-calibrated tree or biogeographical analysis of the order has been published. Here, we elucidate phylogenetic relationships within the order and then conduct time-dependent bioigeographical and diversification analyses by useing a taxon and locus-rich supermatrix approach on one-third of the extant species diversity calibrated with 23 macrofossils and two secondary calibration points. Our results corrobrate previous studies and also suggest several new but poorly supported relationships. Newly suggested relationships are: (1) holo-parastic Mitrastemonaceae is sister to Lecythidacee, (2) the clade formed by Metrastemonaceae + Lecythidaceae is sister to Ericales exluding balsaminoides, (3) Theaceae is sister to the styracoids + sarracenioides + ericoides, and (4) subfamilial relationships with Ericaceae suggest that Arbutoideae is sister to Monotropoideae and Pyroloideae is sister to all subfamily excluding Arbutoideae, Enkianthoideae, and Monotropoideae. Our results indicate Ericales began to diversify 110 Mya, within Indo-Malaysia and Neotropics, with exchange between the two areas and expansion ouf of Indo-Malysia becoming an iimportant area in shaping the extant diversity of many families. Rapid cladogenesis occurred along the backbone of the order between 104 and 105 Mya. Jump dispersal is important within the order in the last 30 My, but vicariance is the most claodgenic driver of disjunctions at deeper levels of the phylogeny. We detect between 69 and 81 shifts in speciation rate throughout the order, the vast majority of which occurred within the last My. We propose that range shifting may be responsible for older shifts in speciation rate, but more recent shifts may be better explained by morphological innovation.
