“…SSD is common in didelphids (Cáceres et al 2007, Isaac 2006, Loretto & Vieira 2008 with males being larger than females in most species. Didelphids are considered polygynous, and in this promiscuous mating system males compete for access to breeding females, which favours phenotypic adaptations that enhance the ability of a male to prevail in male-male contests; e.g.…”

Differences in growth patterns between the sexes of the gracile mouse opossum Gracilinanus microtarsus and the consequences for home range size were investigated in a savanna habitat (cerrado) of south-eastern Brazil. A total of 51 juvenile individuals of Gracilinanus microtarsus was monitored using capture-mark-recapture from November 2005 to August 2006. The increase in body mass of gracile mouse opossums was described using the Gompertz growth model. Male gracile mouse opossums grew faster than females (dimorphic ratio of 1.5). Home range size, estimated with the minimum convex polygon method, was positively related to body mass. Model selection using Akaike's Information Criterion (AIC c ) and incorporating body mass, sex and season as independent variables showed that the best-supported model describing variance in home range sizes included only body mass. Our data suggest that a greater body mass gain in juvenile males is probably the proximate cause of sexual dimorphism in adult gracile mouse opossums and that energetic needs required for growth have a greater influence in home range size.

“…The mammalian fauna from Mato Grosso do Sul state of Brazil was fi rst compiled by Cáceres et al (2008), but checklists have been published for specifi c regions in the state, such as the Acurizal ranch, in the Amolar mountain range (Schaller, 1983;Tomas & Mourão, 2007), the Nhumirim ranch, in the Nhecolândia region of the Pantanal (Alho et al, 1987), the Bodoquena mountain range (Cáceres et al, 2007b;Camargo et al, 2009), Serra de Maracaju (Hannibal & Godoy, 2015), and the Urucum mountains, near Corumbá (Bordignon & França, 2009;Godoi et al, 2010a;Cáceres et al, 2011).

ABSTRACT. We updated the checklist of mammals from Mato Grosso do Sul, Brazil based on primary records only. One hundred and sixty-six mammal species were listed as occurring in the state, 47 of them being medium to large, 47 small mammal and 73 bat species. The listed species are distributed in 31 families: Didelphidae (17 spp.), Dasypodidae (7 spp.), Myrmecophagidae (2 spp.), Cebidae (1 sp.), Callithrichidae (2 spp.), Aotidae (1 sp.), Pitheciidae (1 sp.), Atelidae (1 sp.), Leporidae (1 sp.), Felidae (7 spp.), Canidae (4 spp.), Mustelidae (5 spp.), Mephitidae (2 spp.), Procyonidae (2 spp.), Tapiridae (1 sp.), Tayassuidae (2 spp.), Cervidae (4 spp.), Sciuridae (1 sp.), Cricetidae (22 spp.), Erethizontidae (1 sp.), Caviidae (3 spp.), Dasyproctidae (1 sp.), Cuniculidae (1 sp.), Echimyidae (4 spp.), Phyllostomidae (41 spp.), Emballonuridae (2 spp.), Molossidae (16 spp.), Vespertilionidae (9 spp.), Mormoopidae (1 sp.), Noctilionidae (2 spp.), and Natalidade (1 sp.). These numbers represent an increase of fourteen species with primary records for the state in comparison with the previously published checklist. However, it is evident the scarcity of information at several regions of the state, and the need of implementation of regional zoological collections. The state of Mato Grosso do Sul represent only 4.19% of the Brazilian territory, but the number of mammal species reach 24.13% of the known species occurring in the country.

“…Espécies de Nectomys (N. rattus e N. squamipes) parecem se enquadrar neste panorama, pois os limites das espécies registradas neste estudo coincidem respectivamente com os das bacias do Araguaia e Paraná. Para Oryzomys, O. maracajuensis pode ter seu limite norte de distribuição nas proximidades desta mesma serra, no sul de Goiás (BONVICINO et al, 1996b(BONVICINO et al, , 2002aLANGGUTH & BONVICINO, 2002;BONVICINO, 2003 (BONVICINO et al, 1996a, BONVICINO et al, 2002a, BONVICINO et al, 2002bBONVICINO & ALMEIDA, 2000;CÁCERES et al, 2007).…”

ABSTRACT. Geographic distribution of small non-volant mammals in the Araguaia and Paraná basins, south-central region of Brazil. We collected small mammals in two hydrographic basins in central Brazil, namely the Paraná and Araguaia basins, with the aim of examining the composition of forest dwelling small mammal species and to compare their geographic distributions. Fourteen sites were sampled, eight in the Paraná basin and six in the Araguaia basin. A total of 20 species of small mammals was registered (8 marsupials and 12 rodents), 16 of them in live traps (5,253 trap-nights) and eight in pitfalls (224 trap-nights), adding to a total of 161 captures of 139 individuals. The Paraná basin showed 16 species (trap-nights: 3,115 and 104 respectively) and the Araguaia basin 11 species (trap-nights: 2,138 and 120 respectively), being both richness similar when the rarefaction method was applied. Seven (35%) out of the 20 species recorded occurred in both basins. (Thomas, 1901). The range extension of some species is discussed, in addition to biogeographic considerations. The Caiapós Mountains may have been a geographic barrier for some small mammal species in the face of the retraction and expansion of forests in the past. (Massoia, 1973), Oligoryzomys sp., Proechimys longicaudatus (Rengger, 1830) e P. roberti (Thomas, 1901). A ampliação da distribuição de algumas espécies é discutida, assim como aspectos biogeográficos. A Serra dos Caiapós pode ter sido uma barreira geográfica para algumas espécies de pequenos mamíferos em face da retração e expansão das florestas ocorridas no passado. PALAVRAS-CHAVE.Bacia do Araguaia, Bacia do Paraná, pequenos mamíferos, corredores florestais, Cerrado.O Brasil é o país que possui a maior riqueza de espécies de mamíferos e é um dos que detém o maior número de endemismos, totalizando 131, com destaque para primatas e roedores (FONSECA et al., 1996; MINISTÉRIO DO MEIO AMBIENTE, 2000). Estes números são notáveis devido à presença no país de ricas formações vegetais que propiciam que os mamíferos sejam muito diversos. Estas formações vegetais compreendem a Floresta Amazônica e a Floresta Atlântica, além do Cerrado, que ocupam grande parte do território brasileiro e abrigam a maioria das espécies de mamíferos (FONSECA et al., 1996;EMMONS & FEER, 1997).Dentre os mamíferos, destacam-se as espécies de pequenos mamíferos não voadores e os morcegos, que representam a maioria das espécies de mamíferos. Os pequenos mamíferos não voadores, representados principalmente pelas famílias Didelphidae (entre os marsupiais) e Cricetidae e Echimyidae (entre os roedores),
