| ABSTRACT Bats are key components of ecological networks, and studies in degraded areas are especially important to understand the impact of the human settlements on bats communities. Here, we surveyed the bat fauna in Guaribas Biological Reserve, a protected area in the Atlantic Forest in Paraiba state, northeastern Brazil, and compared it with the bat fauna that occupies the nearby villages. In the villages, we recorded 650 individuals from 14 species, while 1,127 individuals from 20 species were recorded in the Reserve. Diversity estimation pointed out 19 species for the settlements, and 22 for the Reserve. A Bray-Curtis/Sorensen similarity cluster analysis informed that the Reserve areas and the villages form two distinct groups. Additionally, a Wilcox... |

| ABSTRACT This paper consists on a bibliometric analysis of the international influences of the book "Studies on termites from the Mato Grosso State, Brazil", by AGA Mathews (1977). The number of citations has increased over the years after the first citation. Mathews book was cited in articles, reviews, theses, dissertations, books, book chapters, abstracts in conference proceedings, comments and scientific notes. Most these studies are empirical and descriptive. The studies were conducted in 35 countries of the Neotropical, Palearctic, Afrotropical, Nearctic, Australasia and Indomalaya regions. 55% of the studies were carried out in Brazil. The journals Sociobiology and Insectes Sociaux, have social insect studies within its scope, and the highest number... |

| O objetivo deste estudo é descrever aspectos da biologia reprodutiva de Taraba major tais como período reprodutivo, ninhos, ovos, ninhegos, tamanho de ninhada, período de incubação e permanência dos ninhegos no ninho. Os dados foram coletados durante as estações reprodutivas de 2009 e 2010, na fazenda Retiro Novo, município de Poconé, Pantanal, Mato Grosso, Brasil. A procura dos ninhos ocorreu de forma ativa e através da observação dos adultos transportando material para o ninho ou alimento para o filhote. Os ninhos foram visitados com intervalos de três a quatro dias. Foram monitorados 51 ninhos ativos. O período reprodutivo da espécie estendeu-se de outubro a dezembro. O tempo médio de construção dos ninhos foi de 06 ± 1,6 dias (n = 08). Os ovos são de... |

| Triassic dinosaurs of Brazil are found in Santa Maria and Caturrita formations, Rio Grande do Sul state, Brazil. There are three species known from the Santa Maria Formation (Staurikosaurus pricei, Saturnalia tupiniquim and Pampadromaeus barberenai), and two from Caturrita Formation (Guaibasaurus candelariensis and Unaysaurus tolentinoi). These dinosaur materials are, for the most part, well preserved and allow for descriptions of musculature and biomechanical studies. The lateral rotation of the Saturnalia femur is corroborated through calculations of muscle moment arms. The enhanced supracetabular crest of Saturnalia, Guaibasaurus, Staurikosaurus, Herrerasaurus ischigualastensis, Efraasia minor and Chormogisaurus novasi suggests that basal dinosaurs may... |

| Abstract Coastal lagoons and their surrounding habitats often harbour high biodiversity and some of the most threatened ecosystems in the world. However, in the Neotropics the biodiversity is often poorly described, lacking even inventories of species which therefore limits the assessment of threats and the stablishment of efficient conservation measures. We present here lists of bird species recorded at ten sites along the under-studied coastal lagoons of southern Santa Catarina, Brazil, collected mainly from October 2012 to March 2018. We present quantitative data for endemic and threatened species, identify migratory status and highlight distributional novelties. In total, we recorded 229 species encompassing 63 families, including twelve species of... |

| The Cerrado region still receives relatively little ornithological attention, although it is regarded as the only tropical savanna in the world considered to be a biodiversity hotspot. Cerradão is one of the least known and most deforested Cerrado physiognomies and few recent bird surveys have been conducted in these forests. In order to rescue bird records and complement the few existing inventories of this under-studied forest type in the state of São Paulo, we looked for published papers on birds of cerradão. Additionally we surveyed birds at a 314-ha cerradão remnant located in central São Paulo, Brazil, from September 2005-December 2006 using unlimited distance transect counts. Out of 95 investigations involving cerradão bird studies, only 17 (18%)... |

| In uplands and lowlands of Santa Teresa, central Espírito Santo State, Brazil, 405 bird species were confirmed by field, museum, and literature studies. Of these, 16 seem to have disappeared, while 67 other species seem to have been lost from the lowlands (where no large biological reserves exist). Due to a suggestion that human areas add species to beta-diversity, we verified that up to 79 species now present have perhaps "invaded" with human activity (and 10 others are likely to invade), a total similar to that for lost species. However, lost species are often rare and invading species often widespread, resulting in exchange of "Picassos for Coca-Cola bottles." Furthermore, gains exceed losses only when large biological reserves are present, as in the... |

| Over 70% of threatened birds in the state of Rio Grande do Sul, south Brazil, inhabit forest environments. The creation and maintenance of protected areas is one of the most important measures aiming to mitigate these problems. However, the knowledge of the local biodiversity is essential so that these areas can effectively preserve the natural resources. Between 2004 and 2009 we sampled the avifauna in two conservation units in Rio Grande do Sul: Floresta Nacional de Canela (FNC) and Parque Natural Municipal da Ronda (PMR), both representative of the Mixed Humid Forest (Araucaria Forest). A total of 224 species was recorded, 116 at FNC and 201 at PMR, ten of which threatened regionally: Pseudastur polionotus, Odontophorus capueira, Patagioenas... |

| Bithoracochaeta Stein is a Neotropical genus of Muscidae, Coenosiinae, known from ten species recorded from Argentina, Brazil, Costa Rica, Cuba, Ecuador, Guyana, Jamaica, Mexico, Panama, Paraguay, Peru, Puerto Rico, Surinam, Uruguay and Venezuela. The genus is recorded for the first time from Colombia, with the occurrence of the following species: B. annulata Stein, 1911; B. calopus (Bigot, 1885); B. flavicoxa Malloch, 1934; B. leucoprocta (Wiedemann, 1830); B. maricaensis Couri & Motta, 1995 and B. varicornis (Coquilett, 1900). B. nigricoxa, spec. nov. is described from Mexico and Brazil. A brief diagnosis of the known species and a complete description of the new species are given. |
