Apis mellifera L., 1758 têm sido alvo de muitos estudos morfométricos principalmente pela sua importancia ecológica, pela sua grande capacidade de adapta o, sua ampla distribui o e por serem capazes de se estabelecer eficientemente em diversas regi es. O presente trabalho teve como objetivo estudar as varia es da forma em asas e corbículas de operárias de Apis mellifera scutellata Lepeletier, 1836 provenientes das cinco regi es biogeográficas do Brasil utilizando análises morfogeométricas, a fim de verificar a existência de padr es de varia o de forma e tamanho das abelhas africanizadas no Brasil após 16 anos do estudo clássico realizado com esta espécie, possibilitando uma análise espa o-temporal comparativa utilizando recursos tecnológicos atuais para a avalia o de dados morfométricos. Foi realizada uma amostragem em 14 localidades no Brasil, abrangendo as cinco regi es geográficas. A partir de análise de forma e análises multivariadas verificou-se que a forma da asa revelou um padr o geográfico entre as popula es de Apis mellifera no Brasil. As varia es geográficas podem ser atribuídas à grande extens o territorial do Brasil, além de poder estar associada à diferen as entre ecorregi es.

Abstract: the spatial distribution of insects is essential to perform control strategies, to improve sample techniques and to estimate economic losses. we aimed to determine the spatial distribution of nests of acromyrmex crassispinus (forel) in pinus taeda plantations. the experiments were carried out in p. taeda plantations with different ages (treatments: recently-planted, three and six-year old plants). the study took place in rio negrinho and in três barras, sc. three plots of one hectare were delimited in each treatment, and plots were divided in 64 sample units. the analysis of the dispersion index [variance/mean relationship (i), index of morisita (iδ) and k exponent of negative binomial distribution] showed that the majority of the samplings presented random distribution. among the three distributions of probabilities studied: poisson, positive binomial and negative binomial, the poisson distribution was the best model to fit the spatial distribution of a. crassispinus nests in all samplings. the result was a random distribution in the plantings of different ages.

Abstract: the objective of this study was to analyze the body composition of seven to 10 year-old children of high socioeconomic status. therefore, 511 children (274 boys and 237 girls) were submitted to body mass, height and triceps (tr) and subscapular (se) skinfolds thickness anthropometric measurement. based on this information, the following topics were determined: relative body fat (% fat), lean body mass (lbm), body fat distribution (bfd) and sum of the thickness of the tr and se skinfolds (£tsf). two-way anova was used for comparisons between gender and the different age groups, followed by the scheffé post hoc test when p < 0.05. for the children classification according to the categories of body adiposity, frequency distribution was used. a test of comparison between ratios was adopted to verify the differences between gender in each category (p < 0.05). significant differences between gender (p < 0.05) were verified in tr skinfold (girls > boys) and in lbm (boys > girls). significant age effect was identified in all analyzed variables, except for dbf, with the highest values having been found in the 10 year-old group. a high percentage both for boys and girls presented high adiposity index, with superiority for boys (28% vs. 14%, p < 0.01). on the other hand, a larger number of girls presented relative body fat concentrations below the desirable cutting points (15% vs. 3%, p < 0.01). the values of body adiposity found in the present study suggest that a high percentage of children from both gender already present important health risk factors at early ages.

Abstract: regular practice of systematized physical activities in childhood and adolescence may strongly favor the development or maintenance of suitable levels of physical fitness, decreasing hence the risk of incidence of several chronic-degenerative dysfunctions in early ages. thus, the aim of this study was to analyze the body adiposity as well as the motor performance in high socio-economical status children, according to an evaluation for health criterion reference. therefore, 511 students (274 boys and 237 girls), age between 7-10 years were submitted to anthropometrical measurements of body weight, height and skinfolds thickness (tricipital and subscapular) as well as the following motor tests: sitting and reaching (sr); modified abdominal (abd) and 9 minute-run/walk (9min). the data were analyzed according to the cutting points suggested by the physical best (1988). concerning body adiposity; a higher number of students were verified above (33% of boys and 15% of girls, p < 0.01) than below the preestablished criteria. the observed behavior in the different motor tests applied was very similar in both sexes, except for the sr in which a higher proportion of girls fulfilled the adopted criteria (76% vs. 58%, p < 0.01). conversely, the weakest motor development was identified in the 9min test where only 27% of the boys and 32% of the girls (p > 0.05) reached the adopted cutting points. when analyzed together, it was observed that only 15% of the boys and 21% of the girls (p > 0.05) presented satisfactory results in the three motor tests used. the high prevalence of children who were above the health criteria for the body fat amount, associated with the low proportion of subjects who fulfilled the established criteria in the used motor tests group, show that the physical fitness level found in the students investigated is fairly below the expectation. the results suggest the need of developing health educational programs which stimulate more effective participation of y

Abstract: the objective of the present study was to evaluate the effect of using microminerals in organic form on the performance and quality of eggs from commercial laying hens at the end of laying. four hundred and eighty hisex strain hens, 72 to 80 weeks of age, were used. a randomized complete design was used, with six replications and 16 birds for each experimental unit. five diets were evaluated: basal feed supplemented with all microminerals in inorganic form (control); basal feed supplemented with 50% microminerals zinc (zn) + manganese (mn) + copper (cu) in organic form and 50% in inorganic form; basal feed supplemented with 50% zinc in organic form and 50% in inorganic form; basal feed supplemented with 50% manganese in organic form and 50% in inorganic form; and basal feed supplemented with 50% copper in organic form and 50% in inorganic form. there was no effect of diets on egg production, feed intake, food conversion and egg shell percentage and thickness. birds fed basal feed supplemented only with zinc or manganese in organic form produced eggs with lower specific weight. the use of basal feed supplemented with copper in organic form has minimized egg loss. however, the best results (lower egg loss, higher specific weight and higher weight of eggs) were obtained with the basal feed supplemented with microminerals zn + mn + cu in organic form and, therefore, it is recommended for feeding of commercial laying at the end of laying.
