The biogeographical and phylogenetic patterns of Aegla Leach, 1820 were analysed integrating track and cladistic biogeographic methods. We obtained 73 individual tracks, 10 generalised tracks and three nodes. Two taxon-area ...

Aim: Naupactini are highly diverse weevils, widespread in the Neotropical region. Their evolution may have been driven by geological and environmental changes. Our main goals were to explain the biotic diversification of ...

Most Neotropical lowland forest taxa occur exclusively on one side of the Andes despite the availability of appropriate habitat on both sides. Almost all molecular phylogenies and phylogenetic analyses of species assemblages ...

The genera Moscharia (two species) and Polyachyrus (seven species) form a monophyletic group within tribe Mutisieae, subtribe Nassauviinae, defined by the leaves with auricles at their bases, and the capitula with 1-seriate ...

The genus Metrodorea (Rutaceae), with 6 species, has representatives that vary from small shrubs to tall trees, and its leaf sheaths make it unique in the family; it is restricted to South America, with species diversity ...

Arid and semi-arid ecosystems in South America include several different habitats, such as the Peruvian and Atacama Deserts of the Pacific Coast, Monte Desert of central Argentina, Patagonian steppes, Chaco xeric woodlands, ...

Establishing the ancestral ranges of distribution of a monophyletic clade, called the ancestral area, is one of the central objectives of historical biogeography. In this study, I used three common methodologies to establish ...

In order to elucidate the biotic diversification of Asteraceae inhabiting the South American Transition Zone, we undertook a panbiogeographic analysis (based on a parsimony analysis of endemicity) and a cladistic biogeographic ...
