Spermatogenic efficiency in the spiny rat, Trinomys moojeni (Rodentia: Echimyidae)

Animal Reproduction Science, 2010
The spiny rat (Trinomys moojeni) is a rodent found in the Atlantic Forest, which is considered one of the most diverse and threatened biomes in the world. Knowledge on reproductive biology and physiology is critical to conservation and species management, allowing the prevention of extinction and the use of males in natural and artificial reproduction ...

New karyotypes of Atlantic tree rats, genus Phyllomys (Rodentia: Echimyidae)

Genome, 2014
Phyllomys (Echimyidae, Rodentia) is a genus of Neotropical rodents with available cytogenetic data restricted to six out of 13 species, mainly based on simple staining methods, without detailed analyses. In this work, we present new karyotypes for Phyllomys lamarum (diploid number 2n = 56, fundamental number or number of autosomal arms FN = 102) and ...

Karyological and morphometric variation in the genus Thrichomys (Rodentia: Echimyidae)

Mammalian Biology, 2004
Summary We describe two new karyotypes for the echimyid rodent genus Thrichomys , based on samples from the type locality of Thrichomys apereoides (Lund, 1839), Lagoa Santa, Minas Gerais, eastern Brazil, and from the north Pantanal region, near Cuiaba, state of Mato Grosso, western Brazil.

Profile of wild Neotropical spiny rats (Trinomys, Echimyidae) in two behavioral tests

Physiology & Behavior, 2003
The performance of three closely related species of spiny rats was compared in the elevated plus-maze and in the open-field tests. Laboratory rats were also evaluated. It was hypothesized that such tests should reveal differences in anxiety and exploratory profile among the wild species, which differ with respect to habitat, type of social organization
