Association of cellular and molecular alterations in Leydig cells with apoptotic changes in germ cells from testes of Graomys griseoflavus × Graomys centralis male hybrids
(Elsevier, 2014-07)
Spermatogenesis is disrupted in Graomys griseoflavus × Graomys centralis male hybrids. This study was aimed to determine whether morphological alterations in Leydig cells from hybrids accompany the arrest of spermatogenesis ...

Enlarging the knowledge on Graomys griseoflavus (Rodentia: Sigmodontinae) in Patagonia: Distribution and environments
(De Gruyter, 2011-05)
The Leaf-eared mouse Graomys griseoflavus (Waterhouse 1837) is a medium-sized sigmodontine rodent of the tribe Phyllotini (Hershkovitz 1962) that occurs throughout a wide area of the Chaco and Andean-Patagonic domains, ...
Tracking native small mammals to measure fine-scale space use in grazed and restored dry woodlands
(Elsevier Science, 2020-12)
The degradation of dry woodlands in South America by agricultural activities affects wildlife through a decrease in available habitat and fine-scale changes in habitat structure. The impact of land use can be perceived by ...
Chromosomal variability and morphological notes in Graomys griseoflavus (Rodentia, cricetidae, sigmodontinae), from Catamarca and Mendoza provinces, ArgentinaChromosomal variability and morphological notes in Graomys griseoflvus (Rodentia, Cricetidae, Sigmodontinae) from Catamarca and Mendoza provinces, Argentina
(Sociedad Argentina para el Estudio de los Mamíferos, 2014-07)
Genetic variability in rodents is extremely wide and a fruitful field of research. Graomys griseoflavus is a phyllotine rodent, endemic to South America, polymorphic for Rb rearrangements. However, few individuals and ...
Molecular and morphometric evidence validates a Chacoan species of the grey leaf-eared mice genus Graomys (Rodentia: Cricetidae: Sigmodontinae)
(De Gruyter, 2009-12)
Since its formal definition, the genus Graomys (Thomas1916) has been the subject of numerous taxonomicchanges, both at the generic (Tate 1932, Osgood 1947,Pearson 1958, Hershkovitz 1962) and specific level(Cabrera 1961, ...
Phylogenetic relationships among species of the Neotropical genus Graomys (Rodentia: Cricetidae): contrasting patterns of skull morphometric variation and genetic divergence
(Wiley Blackwell Publishing, Inc, 2016-07)
Subtle differences of external traits characterize species of rodents in the Neotropical genus Graomys. On the other hand, the species differ markedly in chromosome number. In the present study, we evaluate the possible ...
