| Con el fin de conocer la percepción y el uso de la avifauna por parte de las comunidades locales en los ecosistemas de la provincia de Salta, se realizaron relevamientos de campo entre 1997-2007 en el Chaco Semiárido, el Monte, la Prepuna, la Puna y la Selva Tucumano- Boliviana de Salta, Jujuy y sur de Bolivia. En el Chaco Semiárido, por medio de observación participante y entrevistas abiertas a cazadores de 37 localidades se identificaron 13 especies con uso alimenticio, algunas de las cuales se usan también para el comercio de carne, mascotas o plumas. En el resto de los ecosistemas se identificaron las especies usadas mediante una actividad escolar en la cual los alumnos dibujaron todos los animales silvestres que conocían, indicando el uso de cada uno,... |

| En este trabajo se analiza la etno-ornitología de los indígenas qom (tobas) del Gran Chaco argentino con el objetivo de iluminar ciertos aspectos del particular entramado de relaciones que los unen con las aves. Se realizó trabajo etnográfico de campo en comunidades de la provincia de Formosa, Argentina, combinado con la identificación de aves in situ y ex situ en colecciones de museos y con guías de aves. Los resultados se organizaron partiendo de considerar las continuidades que existen entre los humanos y las aves con el fin de discutir la forma en que las mismas se intersecan y definen un universo en el que el límite entre lo humano y lo animal se diluye. Posteriormente se examinó cómo estas continuidades modifican las prácticas indígenas, retomando un... |

| Este trabajo explora las percepciones relacionadas con el Cóndor Andino (Vultur gryphus) a través del conocimiento tradicional, las prácticas del habitante rural y el discurso académico asociado a la especie. El estudio se desarrolló en cuatro áreas de las sierras centrales de Argentina, en las provincias de Catamarca, Córdoba (Parque Nacional Quebrada del Condorito), La Rioja y San Juan. Desde la mirada de estos actores sociales, el Cóndor Andino puede ser valorado como una especie clave, emblemática y digna de conservar, pero también puede ser considerada como conflictiva y que debe ser eliminada por el comportamiento cazador que le adjudican algunos lugareños. Por medio de técnicas etnográficas se obtuvo información que evidenció la existencia de una... |

| ABSTRACT The method used for removal of brilliant blue dye may have an influence in interpreting the results of spraying deposition studies. The aim of this study was to assess the number of washings and water volumes for brilliant blue dye removal from soybean leaflets and glass slides in fungicide sprayings with and without adjuvants. A completely randomized experimental design was used in a 3 × 3 × 2 × 4 factorial scheme. The factors consisted of number of washings (1st, 2nd, and 3rd), water volume (15, 20, and 30 mL), target type (soybean leaflets and glass slides), and spray solutions (fungicide ProdutorBR® 0.5 L ha−1 without and with the adjuvants vegetable oil Agr’óleo® 0.5% v v−1, mineral oil Nimbus® 0.5% v v−1, and surfactant Silwet® 0.04% v v−1).... |

| ABSTRACT This research aimed to assess the climatization configuration in a holding pen for dairy cattle considering physiological responses of animals and thermal comfort indexes. Experimental design consisted of 16 cows in a Latin square design containing four groups of four animals (G1, G2, G3 and G4) and four periods (P1, P2, P3 and P4), in which four environments were used as treatments: EXT – external environment (control); SHA – shading with polypropylene mesh, 80% light interception; S+S – shading and water sprinkling; and S+S+V – shading, sprinkling and ventilation. Dry and wet bulb temperature, black globe temperature, wind speed and humidity were recorded during the climatization process, between October 13 and December 7. Subsequently,... |

| ABSTRACT: Sunflower crops are grown in different regions worldwide. However, the stress caused by water excess in the soil impairs this crop growth and yield. The aim of the present study was to determine the response of sunflower plants to long periods of water excess during initial development stages. Water excess treatments were applied at the initial development of these plants at the sowing day, three days after sowing, at plant emergence, and at V2 and V4 stages. The treatments had different duration periods (0, 48, 96, 144, 192, and 240 hours) and were applied at three sowing dates. The current experiment is factorial and was carried out according to a completely random design. Two plant pots, treated under greenhouse conditions, made up the... |

| ABSTRACT Before choosing the method of the estimate of reference evapotranspiraton (ET0) in a region, it is important to evaluate the degree of precision of the model. The present research aimed to evaluate the performance of 30 methods for daily ET0 estimate in the Cassilândia city, Brazil. The meteorological data had been obtained from the National Institute of Meteorology in the period of four years (from April, 2008 to March, 2012). As standard method it was chosen the Penman-Monteith-FAO56, and the comparison of the results was by means of the estimated standard error (ESE), the determination coefficient (R2), the coefficients “a” and “b” of the linear regressions, Willmott's index of agreement (d), Pearson's correlation coefficient (r) and the... |

| ABSTRACT: Sowing occurs in agricultural areas with irregular relief, influencing the quality of seed and fertilizer distribution. The aim of this study was to analyze the performance of different fertilizer metering mechanisms of planters as a function of longitudinal inclination. The experimental design was a completely randomized design with five treatments and six replications. Treatments consisted of five longitudinal inclinations to the metering mechanism (−10, −5, 0, 5, and 10 degrees). The mass of fertilizer collected per minute was considered as a replication. We worked with two types of fertilizers: a mixture of granules and powder. Metering mechanisms used were a horizontal toothed rotor, helical without flow restrictor, helical with lateral... |

| ABSTRACT: The aim of this study was to identify areas susceptible to drought and under desertification in the Brazilian Northeast, more specifically in the states of Alagoas, Pernambuco, and Sergipe. The study was based on the 2000-2014 time period, relative frequency, Vegetation Condition Index (VCI) dataset derived from MOD13Q1 products (vegetation indices derived from the Moderate Resolution Imaging Spectroradiometer sensor). The areas located within the desertification nucleus of Cabrobó, in the southwestern of Pernambuco and surrounding the Águas Belas municipality were considered susceptible to drought and desertification. Some municipalities in the countryside of Alagoas showed a very low relative frequency of VCI data (45-50%), and occurrence of... |

| ABSTRACT: Wood is a material that for years has been used by man for a variety of purposes, particularly in rural and civil constructions and furniture industry. The possibility of shortages of some wood species, the characterization of other unfamiliar species is an alternative source for use in civil and rural construction. This study aimed to determine, with the aid of Brazilian standard NBR 7190, physical and mechanical properties of Castelo (Calycophyllum multiflorum) wood specie. Twelve determinations were obtained by property, totaling 204 experimental values. In the characterization of wood, regression models were used to estimate the values of timber strength and stiffness as a function of apparent density, being density the physical property more... |
