Cromosomas B en especies de roedores sigmodontinos de Argentina
(Consejo Nacional de Ciencia y Tecnología (CONA-CYT) (Paraguay), 2019-12-14)
Los roedores de la subfamilia Sigmodontinae son un linaje independiente diferenciado en Sudamérica. Poseen gran diversidad cromosómica y algunas especies portan cromosomas B o supernumerarios. Estos cromosomas son adicionales ...
DNA barcodes highlight genetic diversity patterns in rodents from lowland desert and Andean areas in Argentina
(John Wiley & Sons, 2022-02-14)
Rodents are an important component of South America fauna. Their high diversity
has motivated researchers to continually review their taxonomy, genetic diversity,
species limits, and phylogenetic relationships. Here, we ...
Chromosome variability and evolution in rodents of the tribe abrotrichini (rodentia, cricetidae, sigmodontinae)
(Springer Research Institute, 2019-11-30)
Rodents are a very diverse group with large chromosome variability. One of the most species rich linage in the Neotropics is the Sigmodontinae. Among them, the tribe Abrotrichini was recently defined and its taxonomy and ...
The Phyllotis xanthopygus complex (Rodentia, Cricetidae) in central Andes, systematics and description of a new species
(Wiley Blackwell Publishing, 2021-08-09)
Phyllotis Waterhouse 1837 is one of the most studied genera of South American cricetid rodents. As currently understood, it includes 20 small to medium-sized species of predominantly rocky habitats. Among them, populations ...
Uncovering cryptic diversity does not end : a new species of leaf-eared mouse, genus Phyllotis (Rodentia, Cricetidae), from Central Sierras of Argentina
(De Gruyter, 2022-03-16)
Based on previously published molecular (mitochondrial) and herein provided morphological (qualitative and quantitative data) evidence, we describe a new species of leaf-eared mouse of the genus Phyllotis. The new species
is ...
Phylogenetic relationships among cryptic species of the phyllotis xanthopygus complex (rodentia, cricetidae)
(Wiley Blackwell Publishing, 2021-01-12)
The leaf-eared mouse, Phyllotis xanthopygus (Waterhouse 1837) is a widely distributed sigmodontine rodent in South America, with populations ranging from central Peru to southern Argentina and Chile. Previous morphological ...
Variabilidad cromosómica y molecular en poblaciones argentinas de Akodon montensis (Rodentia, Cricetidae, Sigmodontinae)
(Consejo Nacional de Ciencia y Tecnología (CONA-CYT) (Paraguay), 2019-12-14)
Akodon montensis es un roedor abundante, cuyo límite de distribución austral es la provincia de Misiones en Argentina. Estudios previos en poblaciones brasileras indican una gran variabilidad cromosómica y molecular en ...
