Relevant genetic contribution of Amerindian to the extant population of Argentina
(Elsevier, 2006-04)
The extant population of Argentina claims to be the most European country of Latin America. The statement has been held for over one century, and started when the Campaign Against the Dessert took place in 1870. This ...
Ornithodoros brasiliensis Aragão (Acari: Argasidae): description of the larva, redescription of male and female, and neotype designation
(Magnolia Press, 2012-01)
Ornithodoros brasiliensis is an endemic tick from Brazil and is very aggressive to humans, resulting in pain, fever and intense inflammatory response. After more than 50 years without report, this species was recently found ...
Genetic relationships among species of Contracaecum railliet & Henry, 1912 and Phocascaris Höst, 1932 (Nematoda: Anisakidae) from pinnipeds inferred from mitochondrial cox2 sequences, and congruence with allozyme data
(Princeps Editions, 2008-09)
The genetic relationships among 11 taxa, belonging to the genus Contracaecum (C. osculatum A, C. osculatum B, C. osculatum (s.s.), C. osculatum D, C. osculatum E, C. osculatum baicalensis, C. mirounga, C. radiatum, C. ...
Revealing the consequences of male-biased trophy hunting on the maintenance of genetic variation
(Springer, 2015-06)
Demographic models accounting for operational sex ratio (OSR) show that male numbers can have a substantial influence on the dynamics of wild populations. We used the Cantabrian capercaillie, a forest bird, as a model to ...
Analysis of body fluid mixtures by mtDNA sequencing: An inter-laboratory study of the GEP-ISFG working group
(Elsevier Ireland, 2007-05)
The mitochondrial DNA (mtDNA) working group of the GEP-ISFG (Spanish and Portuguese Group of the International Society for Forensic Genetics) carried out an inter-laboratory exercise consisting of the analysis of mtDNA ...
Múltiples líneas de evidencias aplicadas al estudio de un individuo prehispánico: Sitio Rancho José, Buenos Aires
(Asociación Argentina de Antropología Biológica, 2016-01)
We present osteological, chronological, isotopic, and ancient DNA (aDNA) information obtained from the analysis of the fragmented human remains of a prehispanic individual recovered at Rancho José site. The site is situated ...
Evidence for spatial clines and mixed geographic modes of speciation for North American cherry-infesting Rhagoletis (Diptera: Tephritidae) flies
(John Wiley and Sons Ltd, 2020-12)
An important criterion for understanding speciation is the geographic context of population divergence. Three major modes of allopatric, parapatric, and sympatric speciation define the extent of spatial overlap and gene ...
First DNA Barcode Reference Library for the Identification of South American Freshwater Fish from the Lower Paraná River
(Public Library of Science, 2016-07)
Valid fish species identification is essential for biodiversity conservation and fisheries management. Here, we provide a sequence reference library based on mitochondrial cytochrome c oxidase subunit I for a valid ...
Four species linked by three hybrid zones: two instances of repeated hybridization in one species group (Genus Liolaemus)
(Frontiers Media S.A., 2021-05-25)
Hybridization is an evolutionary process that can generate diverse outcomes, such as reinforcing species boundaries, generating new species, or facilitating the introgression of locally-adapted alleles into new genomic ...
What does mitogenomics tell us about the evolutionary history of the Drosophila buzzatii cluster (repleta group)?
(Public Library of Science, 2019-11)
The Drosophila repleta group is an array of more than 100 species endemic to the “New World”, many of which are cactophilic. The ability to utilize decaying cactus tissues as breeding and feeding sites is a key aspect that ...
