Ectoparasites of wild rodents from Parque Estadual da Cantareira (Pedra Grande Nuclei), São Paulo, Brazil.

Laboratório de Parasitologia, Instituto Butantan, Av. Vital Brasil 1500, São Paulo, SP 05503-900, Brazil. E-mail: [email protected] Sixteen ectoparasite species were collected from 195 wild rodents, between February 2000 and January 2001, in an Ecological Reserve area of the Parque Estadual da Cantareira, in the municipalities of Caieiras, Mariporã and Guarulhos, State of São Paulo, Brazil. Fifty three percent of the captured rodents were found infested, with the highest prevalences observed for the mites Gigantolaelaps gilmorei and G. oudemansi on Oryzomys russatus; G. wolffsohni, Lalelaps paulistanensis and Mysolaelaps parvispinosus on Oligoryzomys sp. In relation to the fleas, Polygenis (Neopolygenis) atopus presented the highest prevalence, infesting Oryzomys russatus. The highest specificity indices were found for Eubrachylaelaps rotundus/Akodon sp.; G. gilmorei and G. oudemansi/O. russatus; and Laelaps navasi/Juliomys pictipes. When average infestation intensities were related to specificity indices, the relationship was only significant for Brucepattersonius sp. and O. russatus (P<0.05). -

Abstract: The Volta Grande Environmental Unity represents one of the few remnants of Cerrado protected by a reserve in the Triângulo Mineiro region, municipalities of Conceição das Alagoas (19°55' S, 48°23' W) and Miguelópolis (20°12' S, 48°03' W), in the states of Minas Gerais and São Paulo, respectively. The mammalian fauna of this reserve was inventoried between 2003 and 2004 to generate estimates about taxonomic composition, richness, and abundance of species. A sampling effort of 832 trapping-nights resulted in 24 species recorded. Cumulative curves suggest that the overall inventory is not complete and that more species are likely to be registered. -

Comparative Cytogenetics 11(4): 833–892. https://doi. org/10.3897/CompCytogen.v11i4.19925 Abstract 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 of them are species-specific. Additionally, rodents can be an excellent model for chromosome evolution studies since many rearrangements have been described in this group.This work brings a review of cytogenetic data of Brazilian rodents, with information about diploid and fundamental numbers, polymorphisms, and geographical distribution. -
Biosystematics of the Native Rodents of the Galapagos Archipelago, Ecuador
539 BIOSYSTEMATICS OF THE NATIVE RODENTS OF THE GALAPAGOS ARCHIPELAGO, ECUADOR JAMES L. PATTON AND MARK S. HAFNER' Museum of Vertebrate Zoology, University of California, Berkeley, CA 94720 The native rodent fauna of the Galapagos Archipelago consists of seven species belonging to the generalized Neotropical rice rat (oryzomyine) stock of the family Cricetidae. These species comprise three rather distinct assemblages, each of which is varyingly accorded generic or subgeneric rank: (1) Oryzomys (sensu stricto), including 0. galapagoensis [known only from Isla San Cristobal] and 0. bauri [from Isla Santa Fe] ; (2) Nesoryzomys, including N. narboroughi [from Isla Fernandina], N. swarthi [from Isla Santiago], N. darwini [from Isla Santa Cruz] , and N. indefessus [from both Islas Santa Cruz and Baltra] ; and (3) Megalomys curioi [from Isla Santa Cruz]. Megalomys is only known from subfossil material and will not be treated here. Four of the remaining six species are now probably extinct as only 0. bauri and N. narboroughi are known cur- rently from viable populations. The time and pattern of radiation, and the phylogenetic relationships of Oryzomys and Nesoryzomys are assessed by karyological, biochemical, and anatomical investigations of the two extant species, and by multivariate morpho- metric analyses of existing museum specimens of all taxa. These data suggest the following: (a) Nesoryzomys is a very unique entity and should be recognized at the generic level; (b) there were at least two separate invasions of the islands with Nesoryzomys representing an early entrant followed considerably later by Oryzomys (s.s.); (c) both taxa of Oryzomys are quite recent immigrants and are probably derived from 0. -
Rodentia: Cricetidae: Sigmodontinae) in São Paulo State, Southeastern Brazil: a Locally Extinct Species?
Volume 55(4):69‑80, 2015 THE PRESENCE OF WILFREDOMYS OENAX (RODENTIA: CRICETIDAE: SIGMODONTINAE) IN SÃO PAULO STATE, SOUTHEASTERN BRAZIL: A LOCALLY EXTINCT SPECIES? MARCUS VINÍCIUS BRANDÃO¹ ABSTRACT The Rufous-nosed Mouse Wilfredomys oenax is a rare Sigmodontinae rodent known from scarce records from northern Uruguay and south and southeastern Brazil. This species is under- represented in scientific collections and is currently classified as threathened, being considered extinct at Curitiba, Paraná, the only confirmed locality of the species at southeastern Brazil. Although specimens from São Paulo were already reported, the presence of this species in this state seems to have passed unnoticed in recent literature. Through detailed morphological ana- lyzes of specimens cited in literature, the present work confirms and discusses the presence of this species in São Paulo state from a specimen collected more than 70 years ago. Recently, by the use of modern sampling methods, other rare Sigmodontinae rodents, such as Abrawayomys ruschii, Phaenomys ferrugineous and Rhagomys rufescens, have been recorded to São Paulo state. However, no specimen of Wilfredomys oenax has been recently reported indicating that this species might be locally extinct. The record mentioned here adds another species to the state of São Paulo mammal diversity and reinforces the urgency of studying Wilfredomys oenax.

Investigating Evolutionary Processes Using Ancient and Historical DNA of Rodent Species
Investigating evolutionary processes using ancient and historical DNA of rodent species Thesis submitted for the degree of Doctor of Philosophy (PhD) University of London Royal Holloway University of London Egham, Surrey TW20 OEX Selina Brace November 2010 1 Declaration I, Selina Brace, declare that this thesis and the work presented in it is entirely my own. Where I have consulted the work of others, it is always clearly stated. Selina Brace Ian Barnes 2 “Why should we look to the past? ……Because there is nowhere else to look.” James Burke 3 Abstract The Late Quaternary has been a period of significant change for terrestrial mammals, including episodes of extinction, population sub-division and colonisation. Studying this period provides a means to improve understanding of evolutionary mechanisms, and to determine processes that have led to current distributions. For large mammals, recent work has demonstrated the utility of ancient DNA in understanding demographic change and phylogenetic relationships, largely through well-preserved specimens from permafrost and deep cave deposits. In contrast, much less ancient DNA work has been conducted on small mammals. This project focuses on the development of ancient mitochondrial DNA datasets to explore the utility of rodent ancient DNA analysis. Two studies in Europe investigate population change over millennial timescales. Arctic collared lemming (Dicrostonyx torquatus) specimens are chronologically sampled from a single cave locality, Trou Al’Wesse (Belgian Ardennes). Two end Pleistocene population extinction-recolonisation events are identified and correspond temporally with - localised disappearance of the woolly mammoth (Mammuthus primigenius). A second study examines postglacial histories of European water voles (Arvicola), revealing two temporally distinct colonisation events in the UK. -

Box 1346 Ann Arbor, Ml 48106-1346 ABSTRACT South American climbing mice and rats, Rhipidomys, occur in forests, plantations and rural dwellings throughout tropical South America. The genus belongs to the thomasomyine group, an informal assemblage of plesiomorphous Sigmodontinae. Over 1700 museum specimens were examined, with the aim of providing a coherent taxonomic framework for future work. A shortage of discrete and consistent characters prevented the use of strict cladistic methodology; instead, morphological assessments were supported by multivariate (especially principal components) analyses. The morphometric data were first assessed for measurement error, ontogenetic variation and sexual dimorphism; measurements with most variation from these sources were excluded from subsequent analyses. The genus is characterized by a combination of reddish-brown colour, long tufted tail, broad feet with long toes, long vibrissae and large eyes; the skull has a small zygomatic notch, squared or ridged supraorbital edges, large oval braincase and short palate.
