The Use of Geological and Paleontological Evidence in Evaluating Plant Phylogeographic Hypotheses in the Northern Hemisphere Tertiary

TL;DR: The history of the climatic and geographic features of the Tertiary of the Northern Hemisphere agrees with many phylogenetically based phylogeographic hypotheses of living angiosperm genera but indicates that some hypotheses require reanalysis.
Journal ArticleDOI

History and evolution of the arctic flora: in the footsteps of Eric Hulten

TL;DR: There is now excellent fossil, molecular and phytogeographical evidence to support Hultén's proposal that Beringia was a major northern refugium for arctic plants throughout the Quaternary, but most molecular evidence fails to support his proposal that contemporary east and west Atlantic populations of circumarctic and amphi‐Atlantic species have been separated throughout the quaternary.
Journal ArticleDOI

Molecular Analysis of Plant Migration and Refugia in the Arctic

TL;DR: A phylogenetic analysis of chloroplast DNA variation in the purple saxifrage indicates that this plant first occurred in the Arctic in western Beringia before it migrated east and west to achieve a circumpolar distribution.
Journal ArticleDOI

The early Eocene equable climate problem revisited

TL;DR: The early Eocene "equable climate problem" as mentioned in this paper, i.e. warm extratropical annual mean and above-freezing winter temperatures evidenced by proxy records, has remained as one of the great unsolved problems in paleoclimate.
Journal ArticleDOI

Palaeobotanical studies from tropical Africa: relevance to the evolution of forest, woodland and savannah biomes.

TL;DR: Fossil plants provide data on climate, community composition and structure, all of which are relevant to the definition and recognition of biomes, as documented by pollen and carbon isotopes from both West and East Africa.
