| Se realizó un análisis biogeográfico basado en los peces Characiformes de Venezuela con el objetivo de explorar la importancia relativa de los procesos que han contribuido con el establecimiento de los patrones de distribución actuales de la ictiofauna continental venezolana. La información geográfica y filogenética disponible se analizó siguiendo los métodos de Análisis de Parsimonia de Endemismos (PAE) y Análisis de Parsimonia de Brooks (BPA). El PAE señaló fundamentalmente a los Llanos Occidentales y el sur del Amazonas como áreas de endemismo. El BPA realizado con la información filogenética de siete géneros mostró un patrón generalizado con los clados (Caribe + Maracaibo) y ((((Río Negro+Orinoco) + Paria) + Valencia) + Cuyuní), donde se destaca un... |

| Cuckoos are widely distributed, but are concentrated in the tropics, where they occupy a wide range of habitats. Both terrestrial and arboreal behaviors can be found in this group, but there is no consensus on as to whether these behaviors have arisen more than once. Moreover, the historical distribution of cuckoos is poorly understood. This paper presents a biogeographyc analysis of the early history of the distribution of these birds. The analysis was performed by using the Principle of Parsimony based on primary and secondary "Brooks Parsimony Analysis" (BPA). Despite some exceptions, the primary BPA corroborated events of vicariance (general pattern) in the early distribution of cuckoos and a terrestrial ancestor widespread in the Gondwana. The most... |

| In a study on Fanniidae biogeography, Dominguez & Roig-Juñent (2011) argued that the family had a Pangeic origin, Late Jurassic/early Cretaceous (~146 Ma). However, recent literature on Diptera supports that Schizophora radiation occurred during Cenozoic. Fanniidae is a widespread taxon and it was interpreted under the maximum vicariance paradigm; the consequence was an analysis with no alternative hypothesis, but Pangeic origin. We verified that Fanniidae historical narrative was incongruent with the Gondwana sequential break-up. A second analysis, assuming the Fanniidae origin during early Paleocene (65 Ma), showed congruence with recent geological events and with the Muscidae diversification, a closely related Muscoidea family. Our hypothesis... |

| The present study used the previously defined relationships among the snail-killing species of Sepedonea as the starting point for a cladistic biogeography analysis of endemic areas in the Neotropical region. The goal of the study was to use two different data sets to test the possible monophyly of two important biomes in the region: the Amazon and the Atlantic Forest. The possible historical significance of the arid biomes was also investigated. The study used Brooks Parsimony Analysis (Primary BPA). The area groups were based on previous biogeographical classifications of the Neotropial region. The analyses showed Amazonia to be non-monophyletic whereas the Atlantic forest was found to be a natural unit. The importance of including dry areas in the... |
