| La habilidad para caminar y la salud de los huesos son importantes en la producción de pollo de engorda. Se realizó un experimento (factorial 2 x 2) de cuatro tratamientos, con cuatro repeticiones (54 pollos cada una) para evaluar los efectos de las distancias (3m u 8m) y la presencia (CR) o no presencia (NR) de rampas (prisma triangular de 132 cm de ancho x 31 cm de altura x 174 cm de largo con inclinación de 38° por cada lado) entre comederos y bebederos en la resistencia a la rotura de la tibia, rendimiento de la canal y rendimiento productivo. 864 pollos machos (Cobb 500) de un día de edad se criaron convencionalmente y se asignaron al azar en corrales de piso idénticos, con libre acceso al alimento (NRC, 1994) y agua. Se evaluó el rendimiento... |

| 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... |

| Improperly installed or poorly maintained culverts can pose a serious threat to fish by disrupting their habitat and endangering spawning success. Road culverts that are not designed for fish passage frequently can become obstacles. This can be especially problematic for migratory species, but can lead to fragmentation of resident populations as well. This study evaluated 40 culverts of 29 sites within a 25-km radius from Toledo city, Paraná State, southern Brazil, with respect to their likely effects on movement of the local ichthyofauna. We collected data on the shape and length of culverts, culvert material, waterfall height, water column depth, slope, and estimated flow velocity. Culverts were categorized by level of barrier risk for upstream... |

| Although Greek wine is a high quality product, it is not well known in the international marketplace and it has not a recognised brand name. The aim of the current research is to examine the barriers to the export of Greek wine. In-depth Personal interviews were undertaken with producers, managers and people involved in the Greek wine industry. Participants provided information about the current situation and their projections about future. This research is based on qualitative methods. According to the results of the research the barriers could be separated into three basic categories, logistic and financial barriers, marketing and promotion barriers and policy barriers. This research offers Greek wine export managers and people involved in wine industry... |

| The World Trade Organization (WTO) Agreement on Agriculture was signed in June 1994. It accomplished two things: it brought agricultural trade under the rules of WTO, and it set schedules for reducing barriers to trade under the three pillars of liberalization--market access, export assistance, and domestic support. Nine years later there has been precious little liberalization. The new Doha Round has ambitious objectives for agricultural trade liberalization. However, given recent behavior by rich developed countries, it seems unlikely that developing countries will get increased access to Northern markets or reduced competition from subsidized exports, despite their now representing a majority of WTO members. |

| Abstract Aedes (Stegomyia) aegypti (A. aegypti) transmits arboviral diseases of high public health importance, including those caused by Zika virus (ZIKV), Dengue virus (DENV), Chikungunya virus (CHIKV) and Yellow fever virus (YFV). Barreiras is a city with 157,638 inhabitants in the West of the State of Bahia, Northeast of Brazil. The climate is dry, with well-determined and concentrated seasons of rains. The city is crossed by a Federal Highway and by the Rio Grande river. In this study, we aimed to understand the dynamics of mosquito vectors and arboviral diseases in Barreiras. We used correlation statistics to investigate a possible relationship among rains, mosquito abundance and transmission of diseases. In addition, as a preliminary population... |
