Phylogeny, adaptive radiation, and historical biogeography in Bromeliaceae: insights from an eight-locus plastid phylogeny.
TLDR
A bromeliad phylogeny based on eight plastid regions is used to analyze relationships within the family, test a new, eight-subfamily classification, infer the chronology of b romeliad evolution and invasion of different regions, and provide the basis for future analyses of trait evolution and rates of diversification.
Phylogenetic classification of Ericaceae: Molecular and morphological evidence
TLDR
A new classification of Ericaceae is presented based on phylogenetic analyses of nuclear and chloroplast DNA sequence data, morphology, anatomy, and embryology, and three new taxa are described: Oligarrheneae, Richeeae, and Cosmelieae (all within Styphelioideae).
Decline of a biome: evolution, contraction, fragmentation, extinction and invasion of the Australian mesic zone biota
TLDR
The aims are to review and refine key hypotheses derived from palaeoclimatic data and the fossil record that are critical to understanding the evolution of the Australian mesic biota and examine predictions arising from these hypotheses using available molecular phylogenetic and phylogeographical data.
Multiple origins of crassulacean acid metabolism and the epiphytic habit in the Neotropical family Bromeliaceae.
TLDR
A phylogenetic analysis of nucleotide sequences for 51 bromeliad taxa indicated that the last common ancestor of Bromeliaceae was a terrestrial C(3) mesophyte, probably adapted to moist, exposed, nutrient-poor habitats.
Adaptive radiation, correlated and contingent evolution, and net species diversification in Bromeliaceae.
Molecular phylogeny and dating reveals an Oligo-Miocene radiation of dry-adapted shrubs (former Tremandraceae) from rainforest tree progenitors (Elaeocarpaceae) in Australia.
TLDR
This genus, whose distribution was previously thought to reflect Gondwanan vicariance, is shown to have arrived in New Zealand from Australia at least 6-7 million yr ago, and the role of dispersal in explaining the current geographical distribution of Elaeocarpaceae is illustrated.
Evidence for convergent evolution among phylogenetically distant rare species of Tetratheca (Elaeocarpaceae, formerly Tremandraceae) from Western Australia
TLDR
Cladistic analysis of nrDNA internal transcribed spacer and cpDNA trnL-trnF sequences from a range of Tetratheca species indicates that T. aphylla, T. harperi and T. paynterae belong to three separate evolutionary lineages and that the endemism displayed among these taxa to small, disjunct ranges within the same geographic area, is a result of in situ speciation due to historical fragmentation.
Speciation with gene flow on Lord Howe Island
TLDR
It is demonstrated that speciation with gene flow may, in fact, be frequent in some instances and could account for one in five of the endemic plant species of LHI, which challenges current views on the origin of species diversity.
The Sahul–Sunda floristic exchange: dated molecular phylogenies document Cenozoic intercontinental dispersal dynamics
The aim was to characterize the temporal dynamics of the Sahul–Sunda floristic exchange using published dated molecular phylogenies.
Paleo-Antarctic rainforest into the modern Old World tropics: the rich past and threatened future of the "southern wet forest survivors".
TLDR
Understanding how and where lineages from ancient Gondwanan assemblages co-occur today has implications for the conservation of global rainforest vegetation, including in the Old World tropics.
