Biogeography and Evolution of Neotropical species of Capparaceae
We are analyzing the systematic, biogeography and evolution of the Neotropical species of the family Capparaceae, in order to establish whether climatic constraints of the tropical dry forests have influenced its evolution and current distribution. |
Diversity and biogeography of a Neotropical Seasonally dry forest at the Colombian Caribbean (Montes de María)
The phytogeographic and floristic affinities of the “Montes de Maria” (MM: north of Colombia) has been analyzed through Geographic Information Systems, at worldwide, Neotropical and in Colombia scales in order to determine its geographical origin and floristic affinities. In addition, we are analyzing taxonomic diversity (alfa and beta) through equivalent numbers and phylogenetic diversity. |
Systematics and Biogeography of Zygophyllaceae
Zygophyllaceae traditionally has been associated to Neotropical seasonally dry forest (NSDF), distributing discontinuously from northwestern Mexico to northern Argentina and to north-eastern Brazil, including the Antilles. In this forest have been hypothesized that taxa confined to this ecosystem present climatic constraints which have influenced their distribution and shaping a biogeographic pattern mainly associated to the floristic nuclei currently proposed and hence climatic limitations has formed niche conservatism. In this thesis, we are inferring the biogeographic pattern (ecological and historical) in order to understand whether climatic constraints described in this forest have shaped a distributional pattern associated to floristic nuclei and influenced their evolution. |
