We followed seasonal and year-to-year population dynamics for a diverse rodent assemblage in a short-grass prairie ecosystem in southeastern Colorado (USA) for 6 yr. We captured 2,798 individual rodents (range, one to 812 individuals per species) belonging to 19 species. The two most common species, deer mice (Peromyscus maniculatus) and western harvest mice (Reithrodontomys megalotis), general...

Taylor, P.J., Kumirai, A., Contrafatto, G.-C. 2004. Geometric morphometric analysis of adaptive cranial evolution in southern African laminate-toothed rats (Family: Muridae, Tribe: Otomyini). Durban Museum Novitates 29: 110-122. Geometric morphometric analysis of cranial shape and size variation was carried out on laminate-toothed rats (Rodentia: Muridae: Otomyini) from southern Africa, to inve...

During the investigation of terrariums snake pets, two species are reported for first time from Hungary. Females Ophionyssus natricis (Gervais, 1844) were collected body a Boa sp. (Reptilia:Boidae), and females Hirstionyssus butantanensis (Fonseca, 1932) found on new-born mice (Mus musculus Linnaeus) (Rodentia: Muridae) which used as food reptiles. Key Words: parasitic mites, terrarium, new rec...

The collection of small mammals from lacustrine sediments at deli hill (SW of Sivas city, Central Anatolia) contains seventeen species of rodents and two species of lagomorphs. There are four Muridae: Apodemus dominans, Occitanomys (Rhodomys) vandami nov. sp., Micromys bendai, and Muridae gen. et sp. indet., six Cricetidae: Cricetus cf. lophidens, Mesocricetus cf. primitivus, Cricetulus migrato...

three subspecies of mus musculus have been recognized in iran so far. the house mouse (genus0t 0t2tmus2t, species0t 0t2tmus musculus2t) are recognized for their highly conserved morphology and chromosomal structure, but some chromosomal characters offer accurate taxonomic markers in this species that has been shown any unambiguous diagnostic morphological traits. among the chromosomal character...

The present report describes Syphacia (Syphacia) maxomyos sp. n. (Nematoda: Oxyuridae) from two species of spiny rats, Maxomys musschenbroekii from Sulawesi and M. whiteheadi from Sumatra. It is characterized by a cephalic plate extending laterally with dorsoventral constriction and stumpy eggs with an operculum rim reaching pole. It is readily distinguishable by the former feature from all of ...

The taxonomy, distribution, and ecology of six speCies of gerbilline rOdents occurring in the central Namib Desert, four in the genus Gerbi/lurus, are reviewed. The high species richness is unique in southern Africa; moreover, four species have terminal range limits within the area. Higher and more predictable rainfall areas support higher gerbil densities. Population densities and, for at leas...

BACKGROUND Nucleotide substitution rates and G + C content vary considerably among mammalian genes. It has been proposed that the mammalian genome comprises a mosaic of regions - termed isochores - with differing G + C content. The regional variation in gene G + C content might therefore be a reflection of the isochore structure of chromosomes, but the factors influencing the variation of nucle...

A great deal of information concerning the Malayan rats (Muridae, genus Rattus Fischer) exists in the literature. However there is no report on the karyotype of these rats. Karyotype information of wild rats in other parts of the world exists, but is scanty. Makino (1942, 1943, 1949b, 1952c) studied six species of Rattus found in Japan. Most other studies have been confined to Rattus norvegicus...
