Dispersal-vicariance Analyses of Intercontinental Disjuncts: Historical Biogeographical Implications for Angiosperms in the Northern Hemisphere
Ten North Temperate taxa representing diverse angiosperm lineages were analyzed for biogeographic histories using the dispersal-vicariance analysis method to gain insights into the origin and evolution of disjunct distributions in the Northern Hemisphere. Results indicate four general biogeographic patterns: (1) origin and speciation in eastern Asia with subsequent expansion into North America ...
متن کاملPatterns of morphological, biochemical, and molecular evolution in the Oeneis chryxus complex (Lepidoptera: Satyridae): a test of historical biogeographical hypotheses.
Surveys of allozyme allele frequency and mitochondrial DNA (mtDNA) sequence variation were employed to test historical biogeographical hypotheses on the origin and unique distribution of the synchronized biennial, high-altitude butterflies of the Oeneis chryxus complex in western North America. Populations of O. c. stanislaus and O. ivallda from the central and northern Sierra Nevada are indist...
متن کاملA new global palaeobiogeographical model for the late Mesozoic and early Tertiary.
Late Mesozoic palaeobiogeography has been characterized by a distinction between the northern territories of Laurasia and the southern landmasses of Gondwana. The repeated discovery of Gondwanan lineages in Laurasia has led to the proposal of alternative scenarios to explain these anomalous occurrences. A new biogeographical model for late Mesozoic terrestrial ecosystems is here proposed in whi...
متن کاملGenetic Differentiation, Niche Divergence, and the Origin and Maintenance of the Disjunct Distribution in the Blossomcrown Anthocephala floriceps (Trochilidae)
Studies of the origin and maintenance of disjunct distributions are of special interest in biogeography. Disjunct distributions can arise following extinction of intermediate populations of a formerly continuous range and later maintained by climatic specialization. We tested hypotheses about how the currently disjunct distribution of the Blossomcrown (Anthocephala floriceps), a hummingbird spe...
متن کاملTracing Metadiscursive Stance over Time and Across Disciplines: A Comparative Study of English Research Articles
Research in academic writing has revealed a strong tendency on the part of writers to interactively communicate their scientific findings with their readers. In doing so, the writers should take a position while arguing their propositions. This interaction as proposed by Hyland (2005b) takes places having two sides of stance and engagement. This study targeted the stance component of writer-rea...
