Small mammal distributional patterns in Northwestern Argentina
Provedor de dados: Iheringia Série Zoologia
Autores: Sandoval,María L.; Escalante,Tania; Barquez,Rubén.
ABSTRACT Quantitative evaluations of species distributional congruence allow evaluating previously proposed biogeographic regionalization and even identify undetected areas of endemism. The geographic scenery of Northwestern Argentina offers ideal conditions for the study of distributional patterns of species since the boundaries of a diverse group of biomes converge in a relatively small region, which also includes a diverse fauna of mammals. In this paper we applied a grid-based explicit method in order to recognize Patterns of Distributional Congruence (PDCs) and Areas of Endemism (AEs), and the species (native but non-endemic and endemic, respectively) that determine them. Also, we relate these distributional patterns to traditional biogeographic...

Phylogeny of Thylamys (Didelphimorphia, Didelphidae) species, with special reference to Thylamys karimii
Provedor de dados: Iheringia Série Zoologia
Autores: Carvalho,Bianca de A; Oliveira,Luiz F. B; Mattevi,Margarete S.
The genus Thylamys Gray, 1843 lives in the central and southern portions of South America inhabiting open and shrub-like vegetation, from prairies to dry forest habitats in contrast to the preference of other Didelphidae genera for more mesic environments. Thylamys is a speciose genus including T. elegans (Waterhouse, 1839), T. macrurus (Olfers, 1818), T. pallidior (Thomas, 1902), T. pusillus (Desmarest, 1804), T. venustus (Thomas, 1902), T. sponsorius (Thomas, 1921), T. cinderella (Thomas, 1902), T. tatei (Handley, 1957), T. karimii (Petter, 1968), and T. velutinus (Wagner, 1842) species. Previous phylogenetic analyses in this genus did not include the Brazilian species T. karimii, which is widely distributed in this country. In this study, phylogenetic...

Diet variation of the marsupials Didelphys aurita and Philander frenatus (Didelphimorphia, Didelphidae) in a rural area of Rio de Janeiro state, Brazil
Provedor de dados: Mastozoología Neotropical
Autores: Ceotto,Paula; Finotti,Ricardo; Santori,Ricardo; Cerqueira,Rui.
We studied the natural diet of two didelphid marsupial species, Didelphis aurita and Philander frenatus, at a rural area on southeastern Brazil, through fecal sample analysis. Data analysis included intraspecific comparisons (age, gender, and climatic seasons) and interespecific comparisons. Frequencies of food items were compared with other studies to analyze diet differences in a spatial scale. Invertebrates were the most frequent food category found in samples of both species, followed by fruits and vertebrates. There were no differences in the consumption of invertebrates, vertebrates and fruits between sexes in the two species, but both consumed more fruits in more humid months. Juveniles of P. frenatus consumed less vertebrates than adults or...

A Molecular Perspective On The Diversification Of Short-Tailed Opossums (Monodelphis: Didelphidae)
Provedor de dados: Mastozoología Neotropical
Autores: Solari,Sergio.
As currently understood Monodelphis includes more than 22 species and is the most diverse genus of opossums (Didelphimorphia). No complete evaluation of the systematic relationships of its species has been attempted, despite the fact that several species groups and even genus-level groups have been proposed based on morphology, and that some of them are limited to recognized biogeographic regions. Here, genealogic relationships among 17 species were assessed based on phylogenetic analyses of 60 individual sequences (801 base pairs of the mitochondrial cytochrome b gene). The analyses cast doubts on the monophyly of Monodelphis, but species were consistently discriminated into eight species groups: (a) brevicaudata group, with five species, (b) adusta...

Jumping ability in the arboreal locomotion of didelphid marsupials
Provedor de dados: Mastozoología Neotropical
Autores: Delciellos,Ana Cláudia; Vinícius Vieira,Marcus.
Didelphid marsupials are considered to cross discontinuities between arboreal supports using a cautious locomotion, using the prehensile tail as fifth limb. However, this ability was only described for Caluromys philander. We describe and compare the locomotory performance and postural behavior of seven species of didelphid marsupials crossing discontinuities between artificial supports representing arboreal gaps. Individuals were captured in areas of Atlantic Forest in Rio de Janeiro State, Brazil. Animals were stimulated to jump from a fixed horizontal support one meter above the ground to an inclined support of same diameter. We measured the maximum distance of jump (40, 60, 80 or 100 cm) and reach or distance actually reached by the jump. Arboreal...

Terrestrial mammals of the Jequitinhonha River basin, Brazil: a transition area between Atlantic Forest and Cerrado
Provedor de dados: Mastozoología Neotropical
Autores: Geise,Lena; Pereira,Luciana G; Astúa,Diego; Aguieiras,Marcia; Lessa,Leonardo G; Asfora,Paulo H; Dourado,Francisco; Esberárd,Carlos E. L.
Here we present an extensive survey for non-volant mammals along the margins of the Jequitinhonha River, which represents a contact area between the Cerrado and Atlantic Forest biomes. Our data were ob­tained after 13 trapping expeditions (from 2005 to 2012) on both banks of the river, from its source to its mouth, enriched by data obtained from a literature review and voucher specimens deposited in six mammal collections. All collected specimens were identified through their karyotypes and/or morphology. We obtained data for 75 localities (34 at the rigth margin, 42 at the left margin; 30 in the Cerrado and 45 in the Atlantic Forest). We obtained voucher records for 91 species, ca. 17% of all known Brazilian terrestrial non-volant mam­mals. Our results...

Food habits and carnivory by a small size opossum, Gracilinanus agilis (Didelphimorphia: Didelphidae)
Provedor de dados: Mastozoología Neotropical
Autores: Lessa,Leonardo G; Geise,Lena.
We investigated the diet of gracile mouse opossum, Gracilinanus agilis (Burmeister, 1854), from the analysis of 144 fecal samples collected between November 2009 and October 2011 in an area of savanna riparian forest in the Brazilian Cerrado. Invertebrates were the most frequently consumed food items (96.5%) followed by fruits of pioneer species (29.8%) and flowers (6%). We also observed the presence of fragments of bird vertebrae and downs in samples from 2 adult males, this being the first record of predation on small vertebrates by G. agilis. The presence of fragments of birds in the feces of the gracile mouse opossum suggests that despite the small size of this species and its primarily insectivorous habits, small vertebrates may be included in its diet.

A comparison of abundance estimators for small mammal populations
Provedor de dados: Revista Brasileira de Zoologia
Autores: Pacheco,Marcelle; Kajin,Maja; Gentile,Rosana; Zangrandi,Priscilla L.; Vieira,Marcus V.; Cerqueira,Rui.
A major difficulty in the application of probabilistic models to estimations of mammal abundance is obtaining a data set that meets all of the assumptions of the model. In this paper, we evaluated the concordance correlation among three population size estimators, the minimum number alive (MNA), jackknife and the model suggested by the selection algorithm in CAPTURE (the best-fit model), using long-term data on three Brazilian small mammal species obtained from three different studies. The concordance correlation coefficients between the abundance estimates indicated that the probabilistic and enumeration estimators were highly correlated, giving concordant population estimates, except for one species in one of the studies. The results indicate the...

The influence of fire and livestock grazing on the assemblage of non-flying small mammals in grassland-Araucaria Forest ecotones, southern Brazil
Provedor de dados: Revista Brasileira de Zoologia
Autores: Pedó,Ezequiel; Freitas,Thales R. O. de; Hartz,Sandra M.
Grazing and fire, used in pasture regeneration practices, are inter-related activities in livestock management. Both activities affect habitat characteristics by changing the structure of the herbaceous and shrubby vegetation, reducing their biomass and litter cover. This study evaluated the effect of fire and livestock grazing on the assemblage of non-flying small mammals in grassland-Araucaria forest ecotones in southern Brazil. We compared four areas frequently affected by livestock management with four protected areas. Surveys were carried out in four sampling periods, one in each season of 2004. We captured a total of 325 individuals from 12 species of rodents - Akodon montensis Thomas, 1913, Akodon paranaensis Christoff, Fagundes, Sbalqueiro, Mattevi...

Differencial efficiency of two sampling methods in capturing non-volant small mammals in an area in eastern Amazonia
Provedor de dados: Acta Amazonica
Autores: ARDENTE,Natália Carneiro; FERREGUETTI,Átilla Colombo; GETTINGER,Donald; LEAL,Pricila; MARTINS-HATANO,Fernanda; BERGALLO,Helena Godoy.
ABSTRACT This study was the first to evaluate the efficiency of trapping methods in the study of small mammals in the Carajás National Forest, southeastern Brazilian Amazon. It is an area with a unique vegetation type (metalofilic savannah or Canga). The aims of this study were to compare the efficiency of two trapping methods (i.e. live-traps and pitfalls), the bait types used, and evaluate if trapping success varied seasonally. We used four sampling grids, each with six parallel transects. The trap effort for live-traps and pitfalls was 51,840 trap*nights and 10,800 bucket*nights, respectively. We used three types of bait: a paste of peanut butter and sardines, bacon, and bananas. We placed one type of bait in each trap, alternating between points. We...

First record of the bushy-tailed opossum, Glironia venusta, Thomas, 1912, (Didelphimorphia) from Manaus, Amazonas, Brazil
Provedor de dados: Acta Amazonica
Autores: Calzada,Javier; Delibes,Miguel; Keller,Claudia; Palomares,Francisco; Magnusson,William.
A new record of a very rarely observed mammal, the bushy-tailed opossum, Glironia venusta (Didelphimorphia), was obtained for the Adolpho Ducke Forest Reserve, Manaus, Amazonas state, Brazil. Only 17 other records existed of this species, most from the 1980s. There were only three previous records of the species from Brazil (in the states of Pará, Amazonas and Rondônia). This new record supports the notion that G. venusta is a locally rare species throughout its range, but widely distributed in Brazilian Amazonia.

Provedor de dados: Acta Amazonica
Autores: Díaz,María Mónica; Nava,Santiago; Guglielmone,Alberto Alejandro.
In this work the infestation with I. luciae on Didelphimorphia and Rodentia in different environments of Peruvian Amazon was studied. Didelphimorphia was represented by the family Didelphidae. Specimens belonging to Caluromys lanatus, Didelphis marsupialis, Marmosops sp.2, Metachirus nudicaudatus, Philander andersoni and Philander opossum were infested with adults I. luciae and one Micoureus sp. was infested with larvae. In Rodentia, the infestation with I. luciae nymphs was restricted to Hylaeamys perenensis, Hylaeamys yunganus and Oligoryzomys microtis, while one Oecomys bicolor (all Cricetidae) was infested with larvae of this species. The few larvae were found on rodents captured in primary forest. The only significant difference (P &lt; 0.05) in...

ABSTRACT We analyzed the presence of Leptospira spp. in liver and kidney tissue of wild marsupials and rodents trapped in a periurban forest in the eastern Brazilian Amazon. We examined 25 individuals of four marsupial and seven rodent species for the presence of the 16S rRNA gene of Leptospira in the DNA extracted from 47 liver and kidney tissue samples using PCR. We detected positive samples in 12% (3/25) of the individuals, in kidney fragments of two marsupial species (Didelphis marsupialis and Marmosops pinheiroi) and in a liver fragment of one rodent species (Echimys chrysurus). These are the first records of Leptospira spp. in M. pinheiroi and E. chrysurus and it is the first molecular survey of marsupials and rodents in the Brazilian Amazon.

Patterns of arboreal and terrestrial space use by non-volant small mammals in an Araucaria forest of southern Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: ABREU,MAURY S.L.; OLIVEIRA,LARISSA R. DE.
Despite the advances in the techniques for researching arboreal small mammals, detailed ecological data, such as habitat use patterns, are practically nonexistent for many species. Using 150 live-traps installed on the ground, understory (1.0-5.0m) and canopy (&gt;5.0m) we investigated patterns of arboreal and terrestrial space use by small mammals in an Araucaria Forest in southern Brazil (29°29′08″S; 50°12′26″W). We also measured 19 microhabitat variables that could potentially influence the abundance of such mammals on each trap station. The results indicated that Akodon montensis and A. serrensis were mainly terrestrial. Delomys dorsalis was also terrestrial, but it also used understory (17.24% of captures). Juliomys sp. and Gracilinanus microtarsus...

Potential seed dispersal by Didelphis albiventris (Marsupialia, Didelphidae) in highly disturbed environment
Provedor de dados: Biota Neotropica
Autores: Cantor,Mauricio; Ferreira,Letícia Andrade; Silva,Wesley Rodrigues; Setz,Eleonore Zulnara Freire.
Urban forests are usually isolated and highly disturbed, however they are important shelters for tolerant animal species. Their food habits expose the different ecological roles these animals perform in the habitat. We analyzed the contribution of Didelphis albiventris Lund (1840), as a seed disperser, to the vegetation renewal of an urban forest fragment, describing its frugivorous diet and testing the viability of ingested seeds. Both male and female of white-eared opossum included a vast variety of items in their diet, mainly invertebrates and fruits. Fruits were consumed during all year round and seasonality was not observed. The majority of consumed fruits was from pioneer plant species, which is common in disturbed areas, in accordance to the...

Provedor de dados: Biota Neotropica
Autores: Maestri,Renan; Galiano,Daniel; Kubiak,Bruno Busnello; Marinho,Jorge Reppold.
Small land mammals possess features that significantly influence the dynamics of ecosystems and participate in various levels of the food web. In the Brazilian Atlantic Forest the richness of these animals is high, which makes them even more ecologically and numerically relevant in this environment. In this context, we investigated the species composition of small mammals in an unexplored area of southern Brazil, and compared the species composition of this area with other Atlantic Forest regions in order to understand how this community is related to others. The study area was located in an interior Atlantic forest formation, at a transition region between deciduous and Araucaria forests. Small mammals were captured at five collection points using pitfall...

Non-volant small mammals at an Atlantic forest area situated nearby a limestone quarry (Limeira quarry), state of São Paulo, Brazil
Provedor de dados: Biota Neotropica
Autores: Leiner,Natália Oliveira; Silva,Wesley Rodrigues.
Our aim was to survey the non-flying small mammals inhabiting an Atlantic forest area situated nearby a limestone quarry (Limeira quarry), located at Ribeirão Grande municipality (SP), southeastern Brazil. Species were captured with pitfall and Sherman traps along eight pairs of 60 m transects distributed at four different distances from the quarry (60, 220, 740 and 1300 m). Between October 2005 and January 2008, 20 small mammal species (11 rodents and nine marsupials) were captured through 4080 pitfall trap-nights and 2040 Sherman trap-nights. The high values of richness, diversity (H' = 2.65) and equability (J = 0.88), and the presence of endemic and threatened species indicates a preserved study site and small mammal assemblage.
