Molecular phylogenetic analysis of the Persea group (Lauraceae) and its biogeographic implications on the evolution of tropical and subtropical Amphi‐Pacific disjunctions

Abstract

Persea can be retained as a genus by the inclusion of Apollonias barbujana and exclusion a few species that do not fit into the established subgenera. A major revision is recommended for the delimitation between Alseodaphne, Dehaasia, and Nothaphoebe. We suggest that the Persea group originated from the Perseeae-Laureae radiation in early Eocene Laurasia. Its amphi-pacific disjunction results from the disruption of boreotropical flora by climatic cooling during the mid- to late Eocene. The American-Macaronesian disjunction may be explained by the long-distance dispersal.

Tropical Amphi-Pacific disjunctions in the Cladocera (Crustacea: Branchiopoda)

“…Van Steenis, 1962;Heads, 1999;Morley, 2000Morley, , 2001Davis et al, 2002Davis et al, , 2005Givnish and Renner, 2004;Li et al, 2004Li et al, , 2011. (Sharma and Giribet, 2012).…”

“…For a large number of tropical plant families, the main hypothesis proposed to explain disjunctions between the Neotropics and SE Asia, if not by transoceanic long-distance dispersal or vicariance, is the boreotropical scenario (Wolfe, 1975;Morley, 2000Morley, , 2001Tiffney and Manchester, 2001). The number of tropical plant genera with an Amphi-and transPacific disjunction is impressive (van Steenis, 1962) and the boreotropics hypothesis has been confirmed by molecular analysis for a number of families, like the Lauraceae, Annonaceae, Malpighiaceae and the Fabaceae SE, Southeast; N, North; E, East; S, South; NE, Northeast; CE, Central East; C, Central. N o n c o m m e r c i a l u s e o n l y (Lavin and Luckow, 1993;Chanderbali et al, 2001;Davis et al, 2002Davis et al, , 2005Lavin et al, 2005;Li et al, 2011;Christenhusz and Chase, 2013). The discussion is pivotal to our current understanding of biogeography in general and to explain the origins of plants in the Old and New World tropics (Morley, 2000).…”

The first record of Lauraceae fossil woods from the Cretaceous Puerto Yeruá Formation of eastern Argentina and palaeobiogeographic implications

“…and Phoebe Nees, including a total of c. 400 to 450 species. About 80% of these species are distributed in tropical to subtropical Asia, the rest are found in warm-temperate to tropical regions of the New World (Li et al, 2011). These occur mainly in montane forests in Central and South America and range from Mexico to Chile, reaching the Atlantic coastal forests in southeastern Brazil (Chanderbali et al, 2001).…”

“…Bornm. and Persea indica (L.) Spreng., are distributed in the Macaronesian Islands (Li et al, 2011).…”

Laurel Wilt in Natural and Agricultural Ecosystems: Understanding the Drivers and Scales of Complex Pathosystems

“…The family represents some of the earliest angiosperms and has a fossil record dating back to the Mid-Cretaceous [105]. It is well represented on both sides of the Pacific Basin, and the so-called "amphi-Pacific tropical disjunction" of the Persea and Cinnamomum groups in the family has been examined to understand the presence, and the origins and relatedness, of family members in the Eastern and Western Hemispheres [101,106,107].…”
