| A região Centro-Oeste do país se destaca como um pólo produtor de soja e essa produção é escoada, em sua maioria, por meio de rodovias. Pela crise fiscal do Estado, a partir dos anos 80, a malha rodoviária brasileira perde participação nos recursos públicos para investimentos em sua ampliação, conservação e restauração e, essa escassez de investimentos nas rodovias tem reflexos sobre a competitividade internacional da soja dos cerrados, uma vez que o principal modal utilizado para o escoamento dessa produção para os portos das Regiões Sul e Sudeste é o modal rodoviário cujas vias estão em estado precário de conservação, com destaque para trechos das rodovias BR 163 e BR 364 que são vias importantes na região do Centro-Oeste. Por conta disso, 25% da receita... |

| Ryegrass is the main weed in wheat crop, causing yield loss due to competition by environmental resources. The objectives of this study were to estimate the fitness cost of ryegrass biotypes with low-level resistance and susceptible to fluazifop and to investigate the relative competitive ability of these biotypes between themselves and against the crop. Thus, fitness cost and competitive ability experiments were conducted under greenhouse conditions. For the fitness cost experiments, the low-level resistant ryegrass biotypes and those susceptible to fluazifop were used. For competitive ability, the treatments were arranged in a replacement series, with five proportions of the wheat cultivar FUNDACEP Horizonte and the low-level resistant and susceptible... |

| The adsorption of heavy metals in soils affects their behavior in the environment and their bioavailability to plants. The knowledge of the adsorption mechanisms in competitive systems allows a more realistic evaluation of the metals' behavior in the soil than the single metal adsorption. The objectives of this study were (i) to evaluate Cd, Cu, Ni, and Zn adsorption in 14 surface samples (0-0.2 m) of representative soils of the Brazilian humid-tropical region, in competitive and non-competitive systems, and (ii) to establish metal affinity sequences for each soil, based in the maximum adsorption capacity (MAC) estimated by the Langmuir model. The Rhodic Eutrudox, the Kandiudalf Eutrudox, the Arenic Hapludalf, the Arenic Hapludult and the Typic Argiudoll... |

| In anurans, acoustic communication is a major mechanism of pre-zygotic isolation, since it carries information about species recognition. Detailed descriptions of the acoustic properties of anuran advertisement calls provide important data to taxonomist and to the understanding of the evolution of the group. Herein we re-describe the advertisement call of the hylid frog Dendropsophus microps (Peters, 1872) after analyzing a larger sample than that of previous descriptions. We also compare the acoustic properties of the call in two populations and discuss the effect of the presence of the sister species, Dendropsophus giesleri (Mertens, 1950), a potential competitor, in one of the populations. Additionally, we provide information on calling sites and size... |

| In this article, we review allelopathy studies conducted in Brazil or involving plant species that occur in the country. Conceptions and misconceptions associated with allelopathy, as well as some international criteria to be applied in allelopathic research, are presented and discussed. We observed a sharp increase in the number of papers on this subject conducted in Brazil between 1991 and 2010. However, most studies are conducted under laboratory conditions, lack a clear hypothesis or a solid justification, and typically make use of target species that do not co-exist with the donor species under natural conditions. We also found that most studies do not take the additional steps in order to purify and identify the bioactive molecules. We recommend that... |

| El presente trabajo tuvo como objetivo definir las causas que existen en torno al problema de la red de valor del mango Ataulfo en la subcuenca de Atoyac, así como identificar las alternativas de aprovechamiento de las ventajas competitivas propias del territorio y del potencial productivo que permitan generar ingresos a la población. Aunque el mango Ataulfo es líder en rendimiento y representa los mayores ingresos para los productores, presenta bajo nivel competitivo, debido a: altos costos de producción y postcosecha, baja calidad del producto, deficiente organización, escasez de capital de trabajo, escasez de asistencia técnica y capacitación, y poco vínculo entre los agentes: productor, empacador y cliente. Para revertir este fenómeno, es necesario que... |

| The globalisation of processing industry and the consolidation of the international retail trade, together with the increase of imports after the EU access, supported the competition hot up and saturation of domestic food market. Both food processors and food retailers are exposed to increasing competition. In order to maintenance on the market they are increasingly pressed to minimize their costs and/or to accomplish higher prices for products with competitive advantage. Besides of that all participants of the agri-food chain are pressed to intensify marketing support of their goods. Aiming to reduce the costs, some of processors choose the way by the substitution of part of the input material by another, cheaper one. On the other hand, the offer of... |

| In this article we highlight the anticompetitive nature of antidumping (AD) legislation. Antidumping legislation was set up to protect domestic firms from predatory pricing by foreign firms. We argue that protecting highly concentrated industries drastically reduces competition at home. In cases where the industry consists only of one or two firms, import restriction may breed monopolies at the expense of domestic consumers. This article looks at cases filed by the agriculture sector, and at the market concentration of industries in this sector, to illustrate the above possibility. We study the case of fresh tomatoes in detail to further demonstrate the anticompetitive nature of AD legislation. We show the effect of AD legislation on imports, as well as... |

| The Commission's Guidance paper on exclusionary abuse under Article 82 EC is open to three fundamental criticisms. First, it leads to less legal certainty, because the rules suggested are vague and imprecise, because dominant companies will not have the information needed to apply them, and because the Commission is trying to change the law, which it has no power to do. Second, it would lead to some anticompetitive effects, because in practice it discourages price competition, by discouraging individualised price negotiations and retroactive rebates, and by suggesting that the Commission will protect not-yet-as-efficient competitors from price competition. Third, it leads to too many "false positives", i.e., findings of exclusionary abuse that are not... |

| Rhynchosia capitata is a newly emerging threatening weed of summer crops in many Asian countries. We conducted 2-yr experiments to evaluate R. capitata competition with mungbean under irrigated conditions. Rhynchosia capitata was allowed to compete with mungbean for 0, 3, 4, 5, 6, 7 weeks after planting and for full crop season. The competitive ability of R. capitata was assessed by measuring its dry weight, micro and macro nutrient contents and uptake; and its effects on mungbean growth and yield parameters. The results showed that full season weed competition produced highest dry weight of R. capitata and its macro and micronutrient contents and uptake. Yield and yield components of mungbean decreased in a linear fashion with increase in competition... |

| In contrast to single-equation cross-sectional studies of private label share, developing a complete understanding of the nature of the competitive interaction between national brands and private labels requires an understanding of the determinants of both demand and strategic pricing decisions by firms. Consequently, we estimate a simultaneous system of share and price for private labels and national brands. From the empirical results, two measures of market response are derived. The unilateral demand elasticity measures the pure own demand response, while the residual (or total) elasticity also captures the impact of competitive price reaction (Baker and Bresnahan 1985). When taken together, these provide important strategic insights into the pricing... |

| ABSTRACT The biology and ecology of southwestern Atlantic loliginid squids have been intensively researched in the last few decades, mostly off the Brazilian southern coast. However, information gathered by scientific research cruisers, either past or recent, is limited. Three species of loliginid squids - the warm-tempered Doryteuthis sanpaulensis (Brakoniecki, 1984), plus the tropical D. pleii (Blainville, 1823) and Lolliguncula brevis (Blainville, 1823) - were sampled along 16 degrees of latitude on the southwestern Atlantic (22-38°S). The samples were obtained mostly from oceanographic surveys, but also included squids caught by commercial fisheries, and a few specimens from museum collections. Squid response to abiotic variables, morphological... |
