Late Cretaceous Vicariance in Gondwanan Amphibians
Overseas dispersals are often invoked when Southern Hemisphere terrestrial and freshwater organism phylogenies do not fit the sequence or timing of Gondwana fragmentation. We used dispersal-vicariance analyses and molecular timetrees to show that two species-rich frog groups, Microhylidae and Natatanura, display congruent patterns of spatial and temporal diversification among Gondwanan plates i...
متن کاملEvidence for Gondwanan vicariance in an ancient clade of gecko lizards
Vicariance hypotheses of Gondwanan fragmentation have been the prevailing explanation for the distributions of plant and animal taxa in the Southern Hemisphere since the widespread acceptance of plate tectonics in the late, 1960s (Bauer, 1993; Sanmartı́n & Ronquist, 2004). Recently, several molecular studies comparing the timing of cladogenic and vicariant Conservation Biology Graduate Program, ...
متن کاملVicariant origin of malagasy reptiles supports late cretaceous antarctic land bridge.
Since the acceptance of Wegener's theory of plate tectonics in the 1960s, continental drift vicariance has been proposed as an explanation for pan-Gondwanan faunal distributions. Given the recognition of historical connections among continents, it no longer was necessary to invoke hypotheses of dispersal across nearly insurmountable barriers. The application of continental drift vicariance theo...
متن کاملGlobal biogeography of scaly tree ferns (Cyatheaceae): evidence for Gondwanan vicariance and limited transoceanic dispersal
AIM Scaly tree ferns, Cyatheaceae, are a well-supported group of mostly tree-forming ferns found throughout the tropics, the subtropics and the south-temperate zone. Fossil evidence shows that the lineage originated in the Late Jurassic period. We reconstructed large-scale historical biogeographical patterns of Cyatheaceae and tested the hypothesis that some of the observed distribution pattern...
متن کاملBiogeographic analysis reveals ancient continental vicariance and recent oceanic dispersal in amphibians.
Amphibia comprises over 7000 extant species distributed in almost every ecosystem on every continent except Antarctica. Most species also show high specificity for particular habitats, biomes, or climatic niches, seemingly rendering long-distance dispersal unlikely. Indeed, many lineages still seem to show the signature of their Pangaean origin, approximately 300 Ma later. To date, no study has...
