Estimating Ancestral Ranges: Testing Methods with a Clade of Neotropical Lizards (Iguania: Liolaemidae)
(Public Library Of Science, 2011-10)
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 ...
Geographical distribution and ecological diversification of South American octodontid rodents
(Wiley-blackwell Publishing, Inc, 2013-02)
Caviomorph rodents represent one of the most distinctive groups of mammals in southern South America drylands; they colonized South America from Africa via trans-oceanic dispersions in the Eocene (40-50 Ma) and underwent ...
An event model for phylogenetic biogeography using explicitly geographical ranges
(Wiley Blackwell Publishing, Inc, 2017-10)
Aim: To develop and implement a method for phylogenetic biogeography that is both event based and geographically explicit, that is, that uses the geographical ranges observed in the terminals instead of ‘predefined areas.’. ...
Major lineages of Loasaceae subfam. Loasoideae diversified during the Andean uplift
(Academic Press, 2019)
The Loasoideae is the largest clade in the Loasaceae. This subfamily is widespread throughout the Neotropics and centered in the Andes, presenting an excellent opportunity to study diversification across much of temperate ...
Identification of the notothenioid sister lineage illuminates the biogeographic history of an Antarctic adaptive radiation
(Biomed Central Ltd, 2015-06-11)
Background: Antarctic notothenioids are an impressive adaptive radiation. While they share recent common ancestry with several species-depauperate lineages that exhibit a relictual distribution in areas peripheral to the ...
Multiple independent origins of mitochondrial control region duplications in the order Psittaciformes
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012-08)
mitochondrial genomes are generally thought to be under selection for compactness, due to their small size, consistent gene content, and a lack of introns or intergenic spacers. As more animal mitochondrial genomes are ...
Speciesgeocoder: Fast Categorization Of Species Occurrences For Analyses Of Biodiversity, Biogeography, Ecology, And Evolution
(Oxford Univ PressOxford, 2017)
Biogeography of the social wasp genus Brachygastra (Hymenoptera: Vespidade: Polistinae)
Aim The aim of this study was to understand the biogeography of Brachygastra. As the spatial component of evolution is of fundamental importance to understanding the processes shaping the evolution of taxa, the known ...
Ethnic characterization of a population of children exposed to high doses of arsenic via drinking water and a possible correlation with metabolic processes
(e-Century Publishing, 2014-01)
Because the ratio between the two major arsenic metabolites is related to the adverse health effects of arsenic, numerous studies have been performed to establish a relationship between the ability to metabolically detoxify ...
