HISTORICAL BIOGEOGRAPHY: Introduction to Methods
The various methods of biogeography think some of them can be integrated in a single biogeographic approach, with the capability of resolving different problems, such as the recognition of spatial problems.

The whole practice and philosophy of biogeography depend upon the development of a coherent and comprehensive conceptual framework for handling the distribution of organisms and events in space.
Historical Biogeography: An Introduction
This chapter discusses methods in Historical Biogeography, a Conceptual Framework for the Future that aims to define distribution areas and areas of Endemism and describe the phylogeny of species.
Eocene Patagonia Fossils of the Daisy Family
Fossil capitula and pollen grains from the Eocene of Patagonia, southern Argentina exhibit morphological features recognized today in taxa, such as Mutisioideae and Carduoideae, that are phylogenetically close to the root of the asteracean tree.
An extinct Eocene taxon of the daisy family (Asteraceae): evolutionary, ecological and biogeographical implications.
This is the first fossil genus of Asteraceae based on an outstandingly preserved capitulescence that might represent the ancestor of Mutisioideae-Carduoideae, and may have evolved in southern South America some time during the early Palaeogene and subsequently entered Africa, before the biogeographical isolation of these continents became much more pronounced.
Historical biogeography of southern South America
Historical biogeograpohic patterns of relationships among southern and northern South America, North America, and southern temperate areas were investigated by a cladistic biogeographic analysis of…
Using Phylogenetic Diversity Measures to Set Priorities in Conservation: an Example from Southern South America
A modified phylogenetic node-based index that is sensitive to taxic distinctness and ende- micity as well and allows information from diverse taxa to be combined, and allows for preservation of the maximum quantity of taxa in a minimal number of pro- tected areas.

Historical biogeography of Asteraceae from Tandilia and Ventania mountain ranges (Buenos Aires, Argentina)
Tandilia and Ventania are the only systems ofmountain ranges situated in a grassy steppe or "pampas" in the political province of Buenos Aires in Argentina. Tandilia and Ventania have a high taxa…

Evidence supports the hypothesis that sexual reproduction is very restricted or absent in this parasite and some correlations between genetic composition of the parasite and the clinical picture of the infection in human patients are seen.
