| The objective of this study was to compare different graphical dispersion analysis techniques in two- or three-dimensional planes. In this study, the data from different published works were used in order to determine the best methodology for analyzing the genetic diversity of different species. In this study, efficiency is measured by the amount of original distance absorbed by the projection of distances technique, which in the case of major components is equal to the amount of total variation originally available and retained by the principal components used for dispersion purposes. The projection of dissimilarity measurement technique, principal component analysis (PCA), and principal coordinate analysis (PCoA) were used. Considering the analysis by... |

| ABSTRACT The grains of food-type soybean cultivars, which are characterized by the absence of lipoxygenases and the presence of high levels of proteins and isoflavones, are regarded as functional foods with high acceptance by consumers. However, few cultivars of food-type soybeans are currently available in the Brazilian market. The aim of this work was to study the adaptability and stability of various genotypes of food-type soybeans and to compare the performance of methods, which are based on analysis of variance, non-parametric, regression, multivariate and mixed models. Ten lines of food-type soybeans obtained from the Breeding Program of Soybeans for Human Consumption of the State University of Londrina (UEL/BPSHC) and two commercial varieties, the... |

| The Abra alba community from the Gravelines area has been studied since 1976. During this period, sudden and unpredictable variations of the species composition have been observed. These important changes affect a limited number of species without changing the bionomical structure of the community. The species in question are found to be characteristic of this community, and are the more abundant ones. Multivariate statistical methods were used to study quantitative data on the benthic population collected from 1978 to 1992. This analysis was performed in association with air temperature data. Results showed the existence of a six- or seven-year cycle, and this is confirmed by the observation of two complete periods. This cycle, which is found to be... |

| The term Podencos refers to a group of dog breeds from Spain and classification in Group 5 of dog breeds by the Fédération Cynologique Internationale (FCI). The aim of this study was to compare traits morphometric breeds of Podencos; Canario, Ibecenco, Andaluz (small, medium and large) and Orito. Ten morphometric variables were measured in 385 animals (245 females and 140 males), head length, muzzle length, height at withers, rump height, body length, head width, rump width, chest depth, chest girth and the shin circumference. Morphostructural variables were more homogeneous in the Podenco Ibicenco and the Podengo Canario, because for many years there were gradually distinctive trait standards for each breed. The discriminate analysis indicated... |

| Both governmental and non-governmental organizations are engaged in the promotion of soil and water conservation practices in northern Ghana, but adoption is believed to be low. This study thus examines the determinants of conservation practices by farming households in the area. Data for the study was collected from 445 households located in 15 communities in northern Ghana. Univariate, bivariate and multivariate probit models were used to analyse the decision to adopt six conservation practices in the area. Results show the major determinants of adoption are plot and cropping characteristics such as location; and socio-economic and institutional variables such as number of contacts with extension officers, membership in farmer association and distance to... |

| ABSTRACT The bean is a world-class crop and requires adequate water management for higher yield. The objective of this study was to evaluate the growth and the production and to fit multiple regression models to estimate the production components, total biomass accumulation and grain yield of ‘Rosinha’ bean under levels of replacement of evapotranspired water. The experimental design was randomized blocks with four repetitions. Treatments consisted of fractions of crop evapotranspiration (25, 50, 75, 100, 125 and 150% ETc). Growth variables (plant height, number of leaves, leaf area per plant, leaf area index, stem dry mass and leaf dry mass) and production components (number of pods per plant, pod length, pod diameter, pod dry mass, total biomass, pod... |
