Advances in cytogenetics of Brazilian rodents: cytotaxonomy, chromosome evolution and new karyotypic data

Comparative Cytogenetics, 2017
Rodents constitute one of the most diversified mammalian orders. Due to the morphological similarity in many of the groups, their taxonomy is controversial. Karyotype information proved to be an important tool for distinguishing some species because some

Atlantic mammal traits: a dataset of morphological traits of mammals in the atlantic forest of south America [PDF]

, 2018
Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species.

Ontogenetic Variation in Skull Shape of Thrichomys apereoides (Rodentia: Echimyidae) [PDF]

Journal of Mammalogy, 1999
The pattern of change in shape during postnatal development in skulls of punare ( Thrichomys apereoides ) skulls, was studied by geometric morphometric techniques. Skull shape observed in T. apereoides varied both with size and age, but variation in size explains most of the overall change in shape.

Morphological and dietary responses of chipmunks to a century of climate change. [PDF]

, 2016
Predicting how individual taxa will respond to climatic change is challenging, in part because the impacts of environmental conditions can vary markedly, even among closely related species.

A new species of Lentiella (Cestoda: Anoplocephalidae) from Proechimys simonsi (Rodentia: Echimyidae) in Bolivia Una especie nueva de Lentiella (Cestoda: Anoplocephalidae) de Proechimys (Rodentia: Echimyidae) en Bolivia

Revista Mexicana de Biodiversidad, 2008
During a biodiversity survey of mammals and their parasites in the Beni, Bolivia in the summer of 2000, several spiny rats, Proechimys simonsi Thomas, 1900, were collected and examined for parasites. Herein we describe Lentiella lamothei n. sp.
