“…The phylogenetic analysis suggests a biogeographical disjunction between the Caribbean and Pacific basins. Sister groups that are disjunct between the Caribbean and Pacific are apparently rare and have been correlated with the formation of the Isthmus (Namoff et al, 2010), including the effects on global climate and air and oceanic currents. In angiosperms, this disjunction is exemplified in Darwiniothamnus Harling and Erigeron L.

Testing geological models of evolution of the Isthmus of Panama in a phylogenetic framework

The emergence and closure of the Isthmus of Panama had regional and global impacts that were rivalled by few other Cenozoic geological events. The closure of the Central American Seaway and the rise of the Isthmus had dramatic affects on climate and air and oceanic currents worldwide. Formation of the Isthmus also drove terrestrial biotic interchange, ending the isolation of South America by permitting the mixing of its biota with that of North and Central America. A dated phylogenetic tree of a well‐sampled clade of palms in the tribe Trachycarpeae (Copernicia, Pritchardia and Washingtonia) was used to conduct biogeographical analyses. Examination of the timing of lineage dispersal from North into South America was performed and two contrasting temporal hypotheses of the Isthmus formation were tested: occurrence in the Pliocene (c. 5 Mya to the present) or in the Miocene (prior to c. 5 Mya). Copernicia is inferred to have dispersed through the Isthmus of Panama region into South America and subsequently into the Caribbean, where it underwent a rapid radiation. Consistent with a geologically older age for the Isthmus than previously understood, our results support recent geological and palaeobiological data that suggest an early Oligocene to early Miocene model of evolution of the Isthmus of Panama. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, ••, ••–••.

“…Curiously both analyses suggest the ancestral area to be East Africa (DISC), or from somewhere along the arid corridor between present-day Namibia and Tanzania (RRW) rather than coastal areas. Similar relationships between the West Indies and tropical wet Africa have been postulated for mosses (Gradstein et al, 1983), and vascular plants (Givnish et al, 2004;Namoff et al, 2010), but to our knowledge this is the first case of a direct relationship between the Caribbean and non-tropical wet Africa.…”

Aim We investigated the historical biogeography of the Inuleae-Plucheinae (Asteraceae), a group of arid-adapted plants with partly unresolved generic circumscriptions, in order to understand its origin and spatiotemporal evolutionary history in relation to the Cenozoic climate shifts.Location Global, with highest species diversity in the Southern Hemisphere.Methods The spatiotemporal biogeography of the Plucheinae was estimated by both a discrete method using a set of general distribution areas, and a relaxed random walk based on extant species distributions. The topology was time calibrated using a combination of secondary node ages and secondary derived rates for included loci.Results Our results indicate the median age of the Plucheinae to be approximately 15.4 Ma. The biogeographical analyses infer an ancestral origin in southern Africa, with the relaxed random walk analysis narrowing the uncertainty down to an area reaching from coastal Namibia to the western Kalahari. Africa was colonized in a (south)western-(north)eastern direction following the spread of arid habitats. Ancestral representatives of the Plucheinae colonized South America on at least three separate occasions (13.0-4.0, 4.3-3.1 and 4.1-3.7 Ma), with one subsequent spread to North America. Australia was colonized three times between 3.6 and 0.4 Ma. Madagascar and the Mascarenes were colonized at least seven times.Main conclusions The origin of the Plucheinae is estimated to the Namib region, with early speciations and radiations concurring with the timing of aridification of southern Africa, following the increase in strength of the Antarctic Circumpolar Current and subsequent formation of the Benguela Upwelling at c. 11.8 Ma. The current biogeographical distribution of the Plucheinae is best explained by several Neogene long-distance dispersal events from tropical Africa.

The classification of twenty Cynodonteae genera (Bewsia, Craspedorhachis, Ctenium, Dignathia, Farrago, Gouinia, Gymnopogon, Latipes, Leptocarydion, Leptothrium, Lophacme, Lopholepis, Mosdenia, Perotis, Schenckochloa, Toliara, Trichoneura, Trigonochloa, Triplasis, Vaseyochloa) has been poorly understood. The goals of this study were to reconstruct the evolutionary history of the tribe Cynodonteae, emphasizing these twenty genera using molecular data with increased species sampling. A phylogenetic analysis was conducted on 159 samples, of which 94 species (140 individuals) were in the Cynodonteae, using four plastid (rpl32-trnL spacer, ndhA intron, rps16-trnK spacer, rps16 intron) and nuclear ITS 1&2 (ribo somal internal transcribed spacer regions) sequences to infer evolutionary relationships and revise the classification. Strong support was found for six lineages. Craspedorhachis, Ctenium, Dignathia, Gymnopogon, Trichoneura, and Triplasis appear monophyletic; Leptothrium is paraphyletic with Latipes inermis embedded within; Perotis is paraphyletic with Lopholepis and Toliara embedded within; and Gouinia is monophyletic with the resurrection of Schenckochloa. The molecular results sup port the recognition of six subtribes; five (Cteniinae, Farragininae, Gymnopogoninae, Perotidinae, Trichoneurinae) are newly described. A new genus, Tridentopsis, is described; five new combinations, Leptothrium inerme, Perotis arenacea, Perotis ornithocephala, Tridentopsis eragrostoides, and Tridentopsis mutica are made; and Holboellia ornithocephala is lectotypified.
