Spatial analysis of vicariance: A method for using direct geographical information in historical biogeography
(Wiley Blackwell Publishing, Inc, 2011-12)
Based on Hovenkamp's ideas on historical biogeography, we present a method for analysis of taxon history, spatial analysis of vicariance, which uses observed distributions as data, thus requiring neither predefined areas ...
Intra-specific variation in advertisement call of Odontophrynus cordobae (Anura, Cycloramphidae): A multilevel and multifactor analysis
(Brill Academic Publishers, 2013-01)
Advertisement call is a complex signal that can vary at different scales and the characterization of this variation is crucial to understand its adaptive function. In our study, we examined different factors that could ...
Call variability, stereotypy and relationships in syntopy of tetraploid common lesser escuerzo (Anura: Genus Odontophrynus)
(Elsevier Gmbh, 2017-05)
We studied patterns of the geographic variation of mating calls of the common lesser escuerzo Odontophrynus americanus including populations living in syntopy with the closely related O. cordobae and adjacent allopatric ...
Genetic signals of artificial and natural dispersal linked to colonization of South America by non-native Chinook salmon (Oncorhynchus tshawytscha)
(John Wiley & Sons Ltd, 2018-06)
Genetics data have provided unprecedented insights into evolutionary aspects of colonization by non-native populations. Yet, our understanding of how artificial (human-mediated) and natural dispersal pathways of non-native ...
Taxonomic status of the nominal forms assigned to Necromys lactens (Rodentia, Cricetidae) as revealed by molecular and morphometric evidence
(Alliance Communications Group Division Allen Press, 2020-02)
Necromys is a genus of sigmodontine rodent that inhabits grasslands and scrublands in South America. Eight extant species are recognized in the genus; one of these is Necromys lactens, which inhabits high-elevation grasslands ...
‘To and fro’ the southern Andean highlands (Argentina and Chile): Archaeometric insights on geographic vectors of mobility
(Elsevier, 2018-04)
The Andes mountain range is one key physiographic feature of South America with the potential to have acted as a barrier and corridor for human societies. The goal of this paper is to assess from where and how were the ...

(Elsevier Gmbh, 2019-07)
South American foxes are included in the monophyletic genus Lycalopex, with several recent species. Here, the influence of environment about cranial size and shape variations of Lycalopex gymnocercus was explicitly addressed. ...
Scheduling the Main Professional Football League of Argentina
(Informs, 2021-09)
In this paper, we describe our work in scheduling Argentina’s First Division professional football league, the Superliga. Following existing work in sports scheduling, we develop an integer programming model for the Superliga ...
Fossil pollen indicates an explosive radiation of basal Asteracean lineages and allied families during Oligocene and Miocene times in the Southern Hemisphere
(Elsevier Science, 2010-05)
Much of our knowledge of the past distribution and radiation of Asteraceae and allied families depends on the fossil pollen record. In recent years, new discoveries are coming to light from southern Africa, Australia, New ...
