La fiabilidad en la distribución geográfica de las exportaciones argentinas, 1875-1913Reliability in the geographical distribution of Argentine exports, 1875-1913
(Instituto Mora, 2015-09)
El desempeño de la exportación en América Latina durante la primera globalización ha sido un tema muy estudiado en la historiografía. Sin embargo, la calidad de las fuentes de información para su análisis no ha sido tratada ...
Phenotypic variation of leptodactylus cupreus caramaschi, são-pedro and feio, 2008 (Anura, Leptodactylidae)
This study describes for the first time the female of Leptodactylus cupreus and provides new information concerning its geographical distribution, male's morphology and bioacustics. Leptodactylus cupreus, a poorly known ...
SNP Markers as a Successful Molecular Tool for Assessing Species Identity and Geographic Origin of Trees in the Economically Important South American Legume Genus Dipteryx
(Oxford Univ Press Inc, 2020-06-01)
Dipteryx timber has been heavily exploited in South America since 2000s due to the increasing international demand for hardwood. Developing tools for the genetic identification of Dipteryx species and their geographical ...
Geometric morphometrics of the wing as a tool for assigning genetic lineages and geographic origin to Melipona beecheii (Hymenoptera: Meliponini)
(SPRINGER FRANCE, 2011)
The stingless bee Melipona beecheii presents great variability and is considered a complex of species. In order to better understand this species complex, we need to evaluate its diversity and develop methods that allow ...
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.’. ...
Predicting the geographic origin of Spanish Cedar (Cedrela odorata L.) based on DNA variation
The legality of wood products often depends on their origin, creating a need for forensic tools that verify claims of provenance for wood products. The neotropical tree species Cedrela odorata (Spanish cedar) is economically ...
Dissecting maize diversity in lowland South America: Genetic structure and geographic distribution models
(BioMed Central, 2016-08)
Background: Maize landraces from South America have traditionally been assigned to two main categories: Andean and Tropical Lowland germplasm. However, the genetic structure and affiliations of the lowland gene pools have ...

Geographically targeted interventions versus mass drug administration to control Taenia solium cysticercosis, Peru
(Centers for Disease Control and Prevention (CDC), 2021)
Optimal control strategies for Taenia solium taeniasis and cysticercosis have not been determined. We conducted a 2-year cluster randomized trial in Peru by assigning 23 villages to 1 of 3 geographically targeted intervention ...
Traceability of mussel (Mytilus chilensis) in southern Chile using microsatellite molecular markers and assignment algorithms. Exploratory survey
The international seafood trade has adopted the food chain or “from farm to fork” concept in terms of standards and regulations regarding food quality, safety and authenticity, from primary production to the consumer. ...
