The phylogenetic relationships of some Neotropical plant groups have proved to be different
from expectation assuming plate tectonics as the underlying model, and these unanticipated …

Explanations for biogeographic disjunctions involving South America and Africa typically
invoke vicariance of western Gondwanan biotas or long distance dispersal. These …

This paper and this issue attempt to address how, when and why the phenomenal c.
100,000 species of seed plants in tropical America (the Neotropics) arose. It is increasingly …

Phylogeography posits that the sequence of speciation events within a clade should parallel
the geographic migration and isolation of members of the clade through time. The primary …

Knowledge of the evolution and biogeography of the Caribbean biota comes primarily from
faunal studies, in spite of the tremendous richness of the Caribbean flora. The limited data to …

PREMISE OF THE STUDY: The clusioid clade (Malpighiales) has an ancient fossil record
(∼ 90 Ma) and extant representatives exhibit a pantropical distribution represented on all …

Molecular studies reveal highly ordered geographic patterns in plant and animal
distributions. The tropics illustrate these patterns of community immobilism leading to …

Explanations of tropical intercontinental disjunctions involving South America and Africa
typically invoke vicariance of western Gondwanan biotas or long-distance dispersal …

Background There are conflicting views between palaeobotanists and plant systematists/
evolutionary biologists regarding the occurrence of plant speciation in the Quaternary …

Geological and climatological processes that have impacted the biota of the Northern
Hemisphere during the Tertiary are expected to yield little resolution when area cladograms …
