Phylogenetic and biogeographic
analysis of deiphonine trilobites.
The delineation of the northern and southern Amazon, as well as the Napo and Inambari areas of endemism, is complicated, however, by the biogeographic
complexity of the upper Ucayali River and nearby regions in the northern and central Peruvian Amazon.
Clearly, this study has improved our knowledge of the complexity and biogeographic
history of this eastern montane part of Mexico.
In connection with the significant time-gap between individual faunal lists and the inevitable nomenclatorial changes, such species lists do not support biogeographic
research (Soberon & Peterson 2004), nor do they offer easy access to species-richness estimates.
Range size was quantified by incidence in nine biogeographic
regions in the Western Atlantic following REEF classification: 1.
ABSTRACT Since the mid-1990s, the yellow clam Mesodesma maetroides (Deshayes, 1854) has experienced mass mortalities throughout its biogeographic
range (23 [degrees]S to 41[degrees]S) along Atlantic exposed sandy beaches of South America.
range expansion into South America by Coccidioides immitis mirrors New World patterns of human migration.
These data have broad implications for restoration activities where local seed sources are not available and for the biogeographic
history of the taxon.
This is a modification of a system proposed by Wolfe and Roughley  that has proven useful for comparisons between closely related taxa  and evaluations of biogeographic
This life-history pattern, in which fish begin their first year in the Carolinian biogeographic
province, are dispersed to the Virginian province, and return to the Carolinian province before their first winter, has been demonstrated for only one other western North Atlantic finfish species: bluefish (Pomatomus saltatrix).
It is a climatic transition zone, where two major biogeographic
coastal provinces intersect, and species from both northern and southern waters overlap.
