Sobre a distribuição geográfica de Phaenomys ferrugineus (Thomas) (Rodentia, Muridae)

Abstract

ABSTRACT. 00 the geographical distributioo of Phaenomys ferrugineus (fhomas) (Rodeotia, Muridae). The analysis of field notes of specimeos conserved in museums, spe~imens labels, infonnations from bibliography and field observations by the author permited lhe identification oftwo areas (Teresópolis and Sena da Bocaina, in lhe Serra do Mar, states of Rio de Janeiro and São Paulo, respectivelly) where specimens of Phaenomysferrugineus (Thomas, 1894) have been collected in the past. The species is endemic to South Easlern Brazil and has not been collected for more than tifty years. KEY WORDS. Rodeotia, Muridae, Phaenomysferrugineus, geographical distribution, Brasil o rato ferrugíneo Phaenomys ferrugineus (Thomas, 1894) é um pequeno roedor sigmodontino, arborícola, que há mais de meio século não é coletado. O comprimento da cabeça e corpo dos adultos varia de 120 a 160mm e a cauda de 187 a 220mm (n = 4). Não existem dados sobre a biologia da espécie.Devido a escassez de exemplares conservados em museus, o que levantou a hipótese da raridade na natureza, P. ferrugineus foi incluído na Lista Oficial de Espécies da Fauna Brasileira Ameaçada de Extinção (BRASIL 1989).

The presence of Wilfredomys oenax (Rodentia: Cricetidae: Sigmodontinae) in São Paulo state, southeastern Brazil: a locally extinct species?

“…The most updated of those lists was made by Vivo et al (2011), which reported 231 species and described recent advances on mammal studies from which some facts draw attention to São Paulo state mammal fauna, such as the presence of recently described species (Leite et al, 2008;Percequillo et al, 2011;Costa et al, 2011) and even a new genus . New data on mammal species from São Paulo are obtained through new inventories (e.g., Gregorin et al, 2004;Steiner-Souza et al, 2008;Velazco, et al, 2010) and by museum specimens (e.g., Silva et al, 2003;Gregorin et al, 2004;Pavan & Leite, 2011;Garbino, 2011), including records of rare and/or threatened species (e.g., Vaz, 2000;Percequillo et al, 2004;Vivo et al, 2011).…”

Morphological variation in the appendicular skeleton of atlantic forest sigmodontine rodents

“…Semiaquatic forms, such as Nectomys squamipes , regularly swim to disperse, escape predators, or forage (Samuels and Van Valkenburgh,2008). Scansorial forms, such as Oligoryzomys nigripes , mainly use not only the ground and lower strata of the forest but also the shrub layer and canopy (Vieira and Monteiro‐Filho,2003). As with arboreal forms such as Rhipidomys mastacalis , they are characterized by an ability to climb trees (Alho,1982), larger pads on the digits of the hind feet (Thomas,1917), and more elongated digits (Samuels and Van Valkenburgh,2008).…”

“…Scansorial and arboreal species of small mammals may show a pattern of vertical segregation in tropical forests that allows them to share resources, making it possible for species similar in size and morphology to coexist (Emmons and Feer,1997; Vieira and Monteiro‐Filho,2003).…”

Small mammals of the Estação Ecológica de Bananal, southeastern Atlantic Forest, Brazil, with description of a new species of Brucepattersonius (Rodentia, Sigmodontinae)

“…The mean annual temperature ranges between 20° and 33°C; the maximum absolute temperature varies from 36° to 38°C and the minimum absolute temperature varies from 0° to 4°C (Fundação Florestal, 2013). The vegetation at EEB is typical of montane (between 1,100 m and 1,500 m) and high-montane formations (above 1,500 m) of the Dense Ombrophilous Forest, according to the classification of Veloso et al (1991). According to Baitello et al (1998), 75% of the EEB is formed by primary forest, where the forest canopy can reach 30 m high.…”

“…Only 14 specimens are available in collections in Brazil and abroad, including the EEB specimen (Table 36). Some specimens were collected in the end of the XIX century, beginning of the XX century, and in the 1960's (although not published until Vaz, 2000). For several years the species was not collected, but in 1998 a new specimen of P. ferrugineus, an adult male, was captured in Nova Friburgo, Rio de Janeiro, by the Laboratório da Peste da Fundação Nacional de Saúde (Bonvicino et al, 2001).…”
