Se estudió una pequeña colección de muroideos (Rodentia, Muridae) fósiles provenientes del Miembro Media la Formación Nuapua (Holoceno inferior) exhumada en Quebrada (20° 52' S; 63 ° 04' O; 500 m sobre el nivel mar), departamento Chuquisaca, Bolivia. determinaron restos asignables a los sigmodontinos Holochilus chacarius balnearum (Oryzomyini), Necromys sp. (Akodontini), Calomys y Craomys (Phyllotini), todos generos especies actualmente distribuidos sudeste boliviano. discute taxonomía genero región, justificándose través rasgos morfología dentaria diferenciación H. sciureus, brasiliensis. Las poblaciones actuales genera sureste Bolivia se refieren especie chacarius. Asimismo, destaca que registro "Zygodontomys" efectuado por autores previos para muestra fósil corresponde al (= Bolomys, parte). Los escasos conocidos sugieren condiciones chaqueñas Holoceno inferior, similares las área.

(Rodentia: Muridae) from Peninsular Malaysia
There are 25 species of rats and mice (familly Muridae) in peninsular Malaysia (Medway 1978). Of these the karyotypes of 19 species have been described (Yong 1968, 1969 and 1973). The chromosomes of the other 6 species found in this country have, however, not been reported. Of these 6 species, the chromosomes of Hapalomys and Pithecheir have also not been reported from other countries. The pres...
متن کاملMus Terricolor (rodentia, Muridae) Complex: Chromosomal Polymorphism
Mus terricolor chromosomal types I, II, III from different places of India were cytogenetically analyzed. Chromosome types II and III showed polymorphic pericentric inversions of autosomes 2 and 5 present in homozygous or heterozygous condition in the populations. Moreover, besides fixed heterochromatic arms on autosomes 1, 3, and 6; the autosome 8 in terricolor type III showed a large heteroch...

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. from one of these hosts. This species is can be distinguished from L. machadoi Rêgo, 1964 by having a greater total length but smaller maximum width, a ...
متن کاملPhylogeographic Study of Apodemus ilex (Rodentia: Muridae) in Southwest China
BACKGROUND The Mountains of southwest China have complex river systems and a profoundly complex topography and are among the most important biodiversity hotspots in the world. However, only a few studies have shed light on how the mountains and river valleys promote genetic diversity. Apodemus ilex is a fine model for investigating this subject. METHODOLOGY/PRINCIPAL FINDINGS To assess the ge...
متن کاملDietary Ecology of Murinae (Muridae, Rodentia): A Geometric Morphometric Approach
Murine rodents represent a highly diverse group, which displays great ecological versatility. In the present paper we analyse the relationship between dental morphology, on one hand, using geometric morphometrics based upon the outline of first upper molar and the dietary preference of extant murine genera, on the other. This ecomorphological study of extant murine rodents demonstrates that die...
