WebSep 2, 2010 · The first colonization of America by Juniperus (sect. Sabina clade II) occurred in the middle of the Madrean-Tethyan vegetation’s lifespan, and so is entirely compatible with a hypothesis that Juniperus was one of many genera from this vegetation that achieved amphi-Atlantic distributions as part of a Madrean-Tethyan vegetation belt. Sect ... WebThe spatio-temporal diversification history of Pistacia was assessed to test hypotheses on the Madrean-Tethyan and the Eurasian Tethyan disjunctions through phylogenetic and biogeographic analyses. Maximum parsimony and Bayesian methods were employed to analyze sequences of multiple nuclear and plastid loci of Pistacia species. Bayesian …
