Playback of bird songs is a useful technique for species detection; however, this method is usually not standardized. We tested playback efficiency for five Atlantic Forest birds (White-browed Warbler Basileuterus leucoblepharus, Giant Antshrike Batara cinerea, Swallow-tailed Manakin Chiroxiphia caudata, Whiteshouldered Fire-eye Pyriglena leucoptera and Surucua Trogon Trogon surrucura) for different time of the day, season of the year and species abundance at the Morro Grande Forest Reserve (South-eastern Brazil) and at thirteen forest fragments in a nearby landscape. Vocalizations were broadcasted monthly at sunrise, noon and sunset, during one year. For B. leucoblepharus, C. caudata and T. surrucura, sunrise and noon were more efficient than sunset.... |

This is the first systematic survey of bees in the Pantanal wetland, Brazil. We recorded bee species and their floral resources within grassland and natural forest edge habitats in the Pantanal. Surveys were conducted during two to four-days per month, for a total of 12 months. Overall, we recorded 56 bee species visiting a total of 63 flowering plants. Asteraceae and Fabaceae presented the highest number of visited species, however Hyptis suaveolens (Lamiaceae) was the plant most visited by different bee species (18). The most generalist native bee was Trigona fuscipennis visiting a total of 17 flowering plant species. Apis mellifera, an exotic bee, visited 27 species. We also report the overlap (37.5%) in the use of floral resources between the exotic... |

Foi realizado um levantamento fitossociológico em dois fragmentos de floresta higrófila (mata de brejo) no município de Campinas, SP. Em cada fragmento foram alocadas 10 parcelas contíguas de 10 m x 10 m e amostrados todos os indivíduos com PAP (perímetro à altura do peito) <FONT FACE="Symbol">³</FONT> 10 cm. Os dados dos dois fragmentos foram agrupados e analisados em conjunto. Ao todo foram amostrados 955 indivíduos de 55 espécies, 44 gêneros e 29 famílias. Foi observada baixa diversidade em espécies (H = 2,80 nats/indivíduo). As espécies de maior IVI, em ordem decrescente, foram Calophyllum brasiliensis (Clusiaceae), Protium almecega (Burseraceae), Styrax pohlii (Styracaceae), Syagrus romanzoffiana (Arecaceae), Talauma ovata (Magnoliaceae),... |

This study was carried out with the objective of evaluating if the size of forest fragments affects the diversity of bat species. In order to do that, seven fragments were studied in Londrina, Paraná: five small fragments, whose areas varied between 1 and 10 ha; a fragment which is considered medium-sized (Parque Municipal Arthur Thomas - 85,47 ha.); and a large fragment (Parque Estadual Mata dos Godoy - 680 ha.). Thirty three species were collected. Ten species were common to all three types of fragments: Chrotopterus auritus (Peters, 1856), Carollia perspicillata (Linnaeus, 1758), Artibeus fimbriatus Gray, 1838, Artibeus lituratus (Olfers, 1818), Platyrrhinus lineatus (E. Geoffroy, 1810), Pygoderma bilabiatum (Wagner, 1843), Sturnira lilium (E. Geoffroy,... |

The bay of the Tibagi river, a place which goes through quick environmental alterations, has three forest fragments: the "Floresta Nacional do Irati" (3.572 ha), the "Reserva Biológica da Klabin" (11.116 ha) and the "Parque Estadual Mata dos Godoy" (680 ha). Here, Myotis ruber (E. Geoffroy, 1806) and Chiroderma doriae Thomas, 1891 can be found, these are threatened bats, and three species, Pygoderma bilabiatum (Wagner, 1843), Myotis levis (I. Geoffroy, 1824) and Rogheessa tumida H. Allen, 1866, which are presumably threatened. Using the same effort of capture in the three places, it was stated that the "Floresta Nacional do Irati" with low vegetation diversity, showed nine species of bats. The "Parque Estadual Mata dos Godoy", although it's five times... |

The diet, reproduction and activity time of bat species found in Ponta Grossa county, Campos Gerais region, were studied. Collections were conducted in four forest fragments, during 272 hours, on 48 m² of nets and roosting sites; the total capture effort was 1.52.10³ h.m². Eight species (247 individuals) were registered: Artibeuslituratus (Olfers, 1818), Sturniralilium (E. Geoffroy, 1810), Desmodusrotundus (E. Geoffroy, 1810) (Phyllostomidae); Tadaridabrasiliensis (Desmarest, 1819), Eumopsauripendulus (Shaw, 1800) (Molossidae); Eptesicusbrasiliensis (Shaw, 1800), Myotisnigricans (Schinz, 1821), and Histiotusvelatus (I. Geoffroy, 1824) (Vespertilionidae). The Phyllostomidae family was the most frequently captured. Solanaceae, Moraceae, Piperaceae, and... |
