| In the central portion of the Monte desert four small rodent species coexist: Graomys griseoflavus, Akodon molinae, Eligmodontia typus, and Calomys musculinus . Using the Convex Polygon Method, we assessed the home range of these species at different habitats and made comparisons among species, and between sexes and different seasons of the year. We found that home range did not differ among species, but there is a tendency to increase range size as the species corporal size increases. Overlapping of home range was different at different seasons of the year, probably due to different population densities, but home range size was constant along the year. Habitat type and sex affect home range only for G. griseoflavus and A. molinae, respectively. |

| Patagonia, al sur de los 40° S, está actualmente habitada por Chaetophractus villosus y Zaedyus pichiy. Con el objeto de reconstruir la historia de estos armadillos en la porción austral de América del Sur durante el Pleistoceno tardío-Holoceno, compilamos y discutimos datos de registros zooarqueológicos, observaciones de naturalistas y viajeros, especímenes de museos y datos de campo. Encontramos que ambas especies experimentaron una considerable expansión de su distribución hacia el sur. De acuerdo a la evidencia obtenida concluimos que: (a) Patagonia austral estuvo básicamente libre de armadillos durante el Pleistoceno tardío- Holoceno temprano; (b) durante los últimos 10 ka, Z. pichiy invadió progresivamente el sur de la Patagonia desde el norte... |

| The assemblage of arthropods and helminths, present in sigmodontine rodents (Cricetidae) from a broad wetland area of the Río de la Plata, Argentina, was studied. A total of 250 sigmodontines were captured during a two-year sampling period: Scapteromys aquaticus and Oxymycterus rufus were the most abundant hosts, followed by Oligoryzomys nigripes, Akodon azarae, Oligoryzomys flavescens, and Deltamys kempi. There were 33102 parasites collected, corresponding with Rhopalopsyllidae fleas (Siphonaptera), Hoplopleuridae lice (Phtiraptera), Laelapidae and Macronyssidae mites, Ixodidae ticks, and Trombiculidae chiggers (Acari), the trematodes Echinostomidae, Microphallidae, and Dicrocoelidae, the flatworm Ciclophyllidea, the nematods Trichuridae, Spiruridae,... |

| Observed and expected richness, capture success, diversity, dominance, evenness and the effect of latitude on the above variables at the regional level were evaluated with regard to the chiropteran fauna of a semideciduous seasonal forest remnant in the state of Rio Grande do Sul, southern Brazil. Sampling occurred between July 2008 and June 2010 using mist nets erected at ground level. So that chiropteran fauna could be described and compared to other studies in the Atlantic Rainforest throughout the 10°-30°S using multivariate regression. One hundred and sixteen specimens were captured, comprising 9 species and 3 families: Phyllostomidae, Vespertilionidae and Molossidae. Capture success was 0.0008 ind/m²h, with a diversity index (H’) of 1.623;... |

| El presente trabajo describe y compara la morfología del báculo de los roedores altoandinos Thomasomys laniger, T. niveipes, T. princeps, Chilomys instans, Microryzomys minutus y Neomicroxus bogotensis distribuidos en la Cordillera Oriental colombiana dentro del Parque Natural Nacional Chingaza. Adicionalmente, describimos y analizamos el báculo de Thomasomys aureus en dos localidades de la Cordillera Central colombiana. Se diafanizaron 16 penes de individuos adultos con alcian-blue y alizarina para un análisis detallado. Nuestros resultados mostraron que las siete especies exhibieron diferencias morfológicas presentando un báculo complejo con tres dígitos. Dentro del género Thomasomys, las especies T. aureus y T. princeps mostraron una gran... |

| Most Brazilian landscapes lie below 600 m above sea level and studies on the rich Brazilian bat fauna at higher altitudes are scarce. In this study, we investigated bat assemblages associated with different habitats in Chapada do Abanador, Minas Gerais, an area with altitudes ranging from 1000 to 1580 m. Forty-five nights of sampling (153 000 m2h) were performed in semideciduous montane forest, cloud forest and campo de altitude. A total of 137 individuals were captured, belonging to 12 species of the families Phyllostomidae and Vespertilionidae, with a large dominance of the former. Species-accumulation curves reached values close to the asymptote for the campo de altitude and cloud forest habitats, but not for montane forest, suggesting that more species... |

| El objetivo de este trabajo es describir la composición de la comunidad de murciélagos en las zonas boscosas de montaña en la región de Serra Negra, sudeste de Brasil, y comparar la diversidad y riqueza de especies entre las laderas sur y norte. Durante noviembre 2007 hasta marzo 2010 se obtuvieron con redes de niebla un total de 608 capturas de 19 especies de murciélagos pertenecientes a las familias Phyllostomidae y Vespertilionidae. Phyllostomidae constituyó el 97.4% de las capturas, lo que representa 15 especies; Vespertilionidae conformó el 3% de las capturas, con 4 especies. Sturnira lilium fue la especie más frecuentemente capturada (n = 207), seguida de Carollia perspicillata (n = 154), Desmodus rotundus (n = 98) y Artibeus lituratus (n = 50). El... |

| Whereas surveys of the bat fauna are available for some localities in the Brazilian Northeast, studies in the caatinga scrublands are still limited. The aim of this study was to survey the bat fauna in an area of caatinga scrublands in the Private Natural Heritage Reserve (RPPN Serra das Almas), which is located on the Ibiapaba Plateau, State of Ceará. The bat assemblage of the reserve was surveyed in July 2012 (rainy season), and January 2013 (dry season), with a total of 19 sampling nights. We captured 347 individuals of 23 species representing six families. The bat fauna was characterized by the predominance of a few abundant species, in particular phyllostomid frugivores, and many rare species, which is frequent in studies based on mist nets at ground... |

| Six species of bats have been previously reported from the Antillean island of Saint Martin/Sint Maarten- Artibeus jamaicensis, Brachyphylla cavernarum, Molossus molossus, Tadarida brasiliensis, Noctilio leporinus, and Myotis nigricans nesopolus. Our field research reported herein documents an additional three species of bats from the island for the first time- Monophyllus plethodon, Ardops nichollsi, and Natalus stramineus. Re-examination of the single voucher of Myotis nigricans nesopolus has led us to exclude this species from the fauna of Saint Martin/Sint Maarten. Based on our field research and the study of specimens housed in museum collections, we present information on the eight species of bats that we have documented as occurring on Saint... |
