| ABSTRACT The first record of Phyllanthus chacoensis for the Brazilian Amazon is presented, based on a specimen from Rondônia state. The species can be recognized by its cauliflorous inflorescence, staminate and pistillate flowers with 4 sepals, devoid of a floral disk, 4 stamens, 2-carpellary ovary, drupaceous, ellipsoidal fruits, with one seed per locule. The species was previously known only from the central-western and northeastern regions of the Caatinga and Pantanal domains in Brazil. We provide a list of synonyms, a detailed description, an updated geographic distribution map in Brazil, data on habitat and conservation status, illustrations of its reproductive characters, and detailed photographs. We also propose a lectotype for the species. |

| The present study acknowledges the diversity of fossil marsupials from the Gruta dos Moura cave, as well as environmental and climatic aspects during the Quaternary. The results show that this is the largest diversity of Pleistocene marsupials recorded in a single cave: Didelphis albiventris, D. aurita, Gracilinanus agilis, G. microtarsus, Marmosa murina, Monodelphis brevicaudata, M. domesticaand Sairadelphys tocantinensis. Furthermore, the described specimens are also part of the only fossil assemblage unequivocally referable to the late Pleistocene. Paleontological studies suggest an intimate association with dry and open environments with high abundance of water sources. Since most of the identified taxa are characteristic of open forests and gallery... |

| Bragança's socioeconomic situation is highly dependent on estuarine and marine biological resources that are influenced by tidal cycles and climatology. Field measurements (hydrological, hydrodynamic and microbiological variables) were taken in the most urbanized zone from Caeté estuary to characterise the quality of the local environment. During the dry period, the estuary was more eutrophic and presented the highest temperature (30.5 °C in Oct./06), salinity (17 psu in Feb./07), pH (8.24 in Feb./07) and fecal coliform (> 1000 MPN/100 ml in Dec./06 and Feb./07) values. The phytoplankton Cyclotella meneghiniana, Coscinodiscus centralis and other r-strategist species were observed. The lack of basic hydric canalization was responsible for the local... |

| Artisanal fishing on the northern coast of Brazil is characterized by a set of different fishery modalities. Using a multidisciplinary approach, 20 fishery production systems were identified, with distinct characteristics regarding technology and purpose. The characteristics of each system were classified into five dimensions (ecological, economic, social, technological and political). Multidimensional scaling revealed that some of these 20 systems have greater similarities. Thus, a total of 10 groups were identified. |

| This study reports on the occurrence of Molossus coibensis J. A. Allen, 1904, in the Brazilian Amazon and the second record of this species from Brazil. It also presents a comparative analysis with other two small-bodied Molossus species that occur in Brazil: M. molossus (Pallas, 1766) and M. aztecus Saussure, 1860. The report is based on 8 females captured in urban areas of the city of Bragança, in the northern Brazilian state of Pará. Morphometric data and the qualitative comparison of morphological features permited the identification of the specimens as M. coibensis, hitherto known only in Tapirapoan, in the southwestern state of Mato Grosso, west-central Brazil. |

| First record of Chrysomya rufifacies (Macquart) (Diptera, Calliphoridae) from Brazil. In addition to its native fauna, the Neotropical region is known to be inhabited by four introduced species of blow flies of the genus Chrysomya. Up until now, only three of these species have been recorded in Brazil - Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabricius), and Chrysomya putoria (Wiedemann). In South America, C. rufifacies (Macquart) has only been reported from Argentina and Colombia. This study records C. rufifacies from Brazil for the first time. The specimens were collected in an area of cerrado (savanna-like vegetation) in the municipality of Caxias in state of Maranhão, and were attracted by pig carcasses. |

| Species of fruit flies (Tephritidae) were surveyed in a transect of the Amazonian Rainforest in the district of Clevelândia do Norte, municipality of Oiapoque, state of Amapá, Brazil. This study describes the diversity of fruit fly species sampled inside this transect (2.2 linear km). Eleven McPhail traps were serviced weekly from June 2002 to June 2003. A total of 55 samples were obtained, totaling 125 specimens of Tephritidae. Anastrepha Schiner, 1868 was the most abundant and diverse genus, with 18 species caught. Two new species, A. oiapoquensis Norrbom & Uchôa, 2011 and A. siculigera Norrbom & Uchôa, 2011, were discovered in this survey. Anastrepha coronilli Carrejo & González, 1993 (n = 40) was the most abundant species. Six... |
