High resolution inventory of GHG emissions of the road transport sector in Argentina
(Elsevier, 2015-01)
Air quality models require the use of extensive background information, such as land use and topography maps, meteorological data and emission inventories of pollutant sources. This challenge increases when considering the ...
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 ...
Vocalizations, tadpole, and natural history of Crossodactylus werneri Pimenta, Cruz & Caramaschi, 2014 (Anura: Hylodidae), with comments on distribution and intraspecific variation
(2018-03-01)
Crossodactylus werneri was described based on specimens collected in the 1970's at Parque Nacional do Itatiaia, being also reported for nearby localities. We collected specimens that we assigned to C. werneri, and recorded ...
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 ...
Adaptive genetic variation distinguishes Chilean blue mussels (Mytilus chilensis) from different marine environments
(Wiley-Blackwell, 2016)
Chilean mussel populations have been thought to be panmictic with limited genetic structure. Genotyping-by-sequencing approaches have enabled investigation of genomewide variation that may better distinguish populations ...
Species relationships among the wild B genome of Arachis species (section Arachis) based on FISH mapping of rDNA loci and heterochromatin detection: a new proposal for genome arrangement
(Springer, 2010-05)
Arachis hypogaea is an allotetraploid species with low genetic variability. Its closest relatives, all of the genus Arachis, are important sources of alleles for peanut breeding. However, a better understanding of the ...
DNA barcode discovers two cryptic species and two geographical radiations in the invasive drosophilid Zaprionus indianus
(Blackwell Publishing, 2008-05-01)
Comparing introduced to ancestral populations within a phylogeographical context is crucial in any study aiming to understand the ecological genetics of an invasive species. Zaprionus indianus is a cosmopolitan drosophilid ...
In Silico analysis of Gastric carcinoma Serial Analysis of Gene Expression libraries reveals different profiles associated with ethnicity
(2008)
Abstract
Worldwide gastric carcinoma has marked geographical variations and worse outcome in patients from the West compared to the East. Although these differences has been explained by better diagnostic ...
Centralized admission and the student-college match
(2017)
Decentralized assignments in the education market have been increasingly replaced by centralized ones. However, empirical evidence on these transitions is scarce. This paper examines the adoption of centralized admissions ...
