The phylogeography of
Hall, Jason P W; Harvey, Donald J
Summary of Points:
·
In the study, a fully resolved cladogram
for 19 species in the Charis cleonus
group of riodinid butterflies, which have closely parapatric ranges throughout the Amazon basin, is used to
derive an area cladogram for the region.
·
It represents the first comprehensive species-level analysis using
insects and results in a hypothesis of Amazonian area relationships that is the
most detailed to date.
·
The Charis area cladogram
is interpreted as supporting an historical vicariant
split between the Guianas and the remainder of the
Amazon and then between the upper and lower Amazon.
·
The area relationships for riodinid
butterflies show substantial congruence with those presented from the
literature for amphibians, reptiles, birds, primates, rodents, and marsupials,
suggesting a common vicariant history for these
organisms.
·
Charis cleonus
group species distributions are noticeably larger around the upland periphery
of
