Abstract: The objective of this work was to associate the energy digestible level of the diet to ovary development in post larval stage. Twenty-four female fish were used with weight and average initial length of 0.33 ± 0.11 g and 2.94 ± 0.39 cm, respectively. There were four treatments: 2600, 2700, 2800, and 2900 kcal of DE/kg of ration. Digestible energy levels influenced the final weight up to the estimated level of 2757.142kcal/kg. However, there was no significant effect for total length, gonad weight, and gonadossomatic index in females. The level of digestible energy did not provide better initial development of the ovary. This information may guide new experiments, to improve the conditions of cultivation, to value the activity on the economic sense as well as increase the number of fingerlings for aquaculture. Objetivou-se associar o nível de energia digestível da dieta com o desenvolvimento ovariano em estagio pós-larval. Foram usadas 24 fêmeas com peso e comprimento médio inicial de 0,33 ± 0,11g e 2,94 ± 0,39cm, respectivamente. Foram realizados 4 tratamentos: 2600; 2700; 2800 e 2900kcal de ED/Kg de ra o. No presente estudo, o nível de energia digestível influenciou no peso final até o nível estimado de 2757,142kcal/kg. Entretanto, n o apresentou efeito significativo para comprimento total, peso da g nada e índice gonadossomático das fêmeas. O nível de energia digestível n o proporcionou melhor desenvolvimento inicial do ovário. Essas informa es poder o nortear novos experimentos, melhorar as condi es de cultivo, valorizar a atividade no sentido econ mico, assim como aumentar o número de alevinos destinados à aquicultura.

Abstract: Este artigo analisa de que forma a legisla o do município de Fortaleza e as políticas públicas cujo enfoque seja a diversidade sexual, durante a gest o Fortaleza Bela 2005-2008, contribuíram para conferir, do ponto de vista local, prote o jurídica e reconhecimento aos homossexuais como minoria dentro de um cenário de exclus o muito mais amplo. Para tanto, buscou-se tra ar um breve perfil histórico da homossexualidade no Brasil e no mundo para, logo em seguida, situar o grupo heterogêneo formado por gays, lésbicas, bissexuais, transexuais e transgêneros como minoria ou grupo vulnerável, independente da distin o teórica que se queira adotar, no sentido de constatar a viola o dos seus direitos sexuais e demais direitos de liberdade e igualdade, sua rela o de inferioridade aos padr es sociais heteronormativos, resistência contra-hegem nica por meio da cidadania e o delineamento de estratégias discursivas contra o homofobismo. Nesse sentido, a dignidade do igual respeito n o é suficiente para dirimir os conflitos por discrimina o de orienta o sexual, sendo necessário que haja diferencia o quando a igualdade de tratamento os inferiorizar. Dessa feita, o município de Fortaleza, nesse período, teve papel importante na formula o de políticas públicas de visibilidade da cidadania LGBTT e na aplica o de normas jurídicas que sancionassem administrativamente condutas homofóbicas e garantissem os benefícios previdenciários aos parceiros e parceiras de servidores municipais que s o do mesmo gênero do segurado. Porém, a ades o da sociedade civil n o foi unanime e, mediante dois exemplos, foi possível demonstrar a intolerancia com a qual os homossexuais s o tratados. Palavras-chave: Homossexuais. Minorias.

Abstract: in order to avoid no desired crosses to combine four types of barley, the differential effect of spike type and grain on final yield and its components was studied in twelve genotypes at duitama and samacá (boyacá, colombia) in a split-plot design with four replications. an analysis of variance was practiced, locally, for each variable taking the mean genotype groups as a treatment and not an individual genotype. differences among treatments were determined by a least significance difference. two-rowed barley genotypes gave a higher number of effective tillers (samacá) and heavier kernels (duitama, samacá); while, six-rowed barley genotypes had a greater number of kernels/spike (duitama, samacá). additionally, in duitama, hull absent kernel barley genotypes produced a greater number of kernels/spike; but, hulled kernel barley genotypes gave heavier kernels. the row number x hull prevalence interaction only affected the kernels/spike number (duitama). as for the yield of dry grain in duitama, none of the sources of variation presented significant effects. with regard to the row number, this may be due to compensation between the yield components, some higher than others in one or another type, between the two-rowed and six-rowed barleys evaluated.

Abstract: Con el objeto de poder determinar en el futuro los cruzamientos más deseables al combinar cuatro tipos de cebada, se estudió en Duitama y en Samacá (Boyacá, Colombia), el efecto diferencial del tipo de espiga y de grano en el rendimiento final y sus componentes, de doce genotipos, en un dise o de parcelas divididas, con cuatro repeticiones. Se efectuó análisis de varianza para cada una de las localidades y características evaluadas, tomando el promedio del grupo de los genotipos involucrados. La comparación de medias de tratamientos, se realizó por el método de Diferencia Mínima Significativa. Los genotipos con espigas de dos carreras produjeron mayor número de macollas efectivas (Samacá) y granos más pesados (Duitama, Samacá), mientras que los de seis carreras tuvieron un mayor número de granos por espiga (Duitama, Samacá). Adicionalmente, en Duitama, los genotipos con granos desnudos produjeron mayor número de granos, pero los de granos cubiertos dieron granos más pesados. La interacción entre el número de carreras y el tipo de grano solo presentó significancia para el número de granos por espiga, en la localidad de Duitama. En cuanto al rendimiento de grano seco en Duitama, ninguna de las fuentes de variación mostró efectos significativos. Respecto al número de carreras, se pudo deber a compensación entre los componentes del rendimiento, algunos mayores y otros menores en uno u otro tipo, entre las cebadas de dos y seis carreras evaluadas. In order to avoid no desired crosses to combine four types of barley, the differential effect of spike type and grain on final yield and its components was studied in twelve genotypes at Duitama and Samacá (Boyacá, Colombia) in a split-plot design with four replications. An analysis of variance was practiced, locally, for each variable taking the mean genotype groups as a treatment and not an individual genotype. Differences among treatments were determined by a Least Significance Difference. Two-rowed barley genotypes gave a higher number of effective tillers (Samacá) and heavier kernels (Duitama, Samacá); while, six-rowed barley genotypes had a greater number of kernels/spike (Duitama, Samacá). Additionally, in Duitama, hull absent kernel barley genotypes produced a greater number of kernels/spike; but, hulled kernel barley genotypes gave heavier kernels. The row number x hull prevalence interaction only affected the kernels/spike number (Duitama). As for the yield of dry grain in Duitama, none of the sources of variation presented significant effects. With regard to the row number, this may be due to compensatio
Reproductive isolation among three populations of the genus Grammostola from Uruguay (Araneae, Theraphosidae)
Postiglioni, Rodrigo;Costa, Fernando G.;
Iheringia. Série Zoologia , 2006, DOI: 10.1590/S0073-47212006000100013
Abstract: ethological isolation of individuals from three allopatric grammostola populations of uruguay, g. iheringi (keyserling, 1891), g. mollicoma (auserer, 1875) northern population and g. mollicoma southern population, was tested under laboratory conditions. grammostola iheringi behaved as a reproductive isolated species, whereas the two populations of g. mollicoma did not show ethological isolation between them. however, ecological isolating reproductive mechanisms could be acting on g. mollicoma populations. artificial burrows seem to be important for reproductive isolation in these species.

Einstein (S?o Paulo) , 2008,
Abstract: Enhanced pain syndromes have their prevalence increased withold age. Fibromyalgia, among them deserves special attention. Itscauses are still unknown. Fibromyalgia syndrome affects mainlyfemales and is characterized by generalized musculoskeletal pain,fatigue, sleep disturbances, diffuse stiffness and other psychic signsand symptoms. Diagnosis is essentially based on the 1990 AmericanCollege of Rheumatology Classifi cative Criteria. In this chapteraspects related to its treatment and prognosis are also discussed.
Inferring possible population divergence in Espeletia pycnophylla (Asteraceae) through morphometric and paleogeographic approaches

Revista de Biología Tropical , 2010,
Abstract: the phenotypic structure within and between plant populations is generally influenced by their distribution patterns in space and time; therefore, the study of their divergence is a central issue for the understanding of their microevolutive processes. we boarded the hypothesis that three populations of espeletia pycnophylla show phenotypic divergence as one of the possible implications of their geographic isolation in the southern colombian andes. we used the elliptic fourier descriptors (leaf shape) and traditional leaf morphometry (leaf size) of 347 leaves to measure inter and intra-population variation and a comparison between a paleogeographic reconstruction with an actual estimate of the distribution areas of e. pycnophylla in order to identify their main changes during the last 14 000 years. the three populations showed significant differences in leaf morphometry and a positive correlation between the matrices of morphometric and geographic dissimilarities, indicating that the inter-population divergence increases between further populations, so that the morphometric structure reflects their spatial distribution. the geographical and paleogeographical estimates evidenced a conspicuous process of reduction and fragmentation of the distribution area of e. pycnophylla since the late-glacial until the holocene. we suggest that these results support possible scenarios of vicariance events, which allow us to approach the divergence of these populations in terms of their historic biogeographic relations. however, genetic analyses are still needed to support these results. rev. biol. trop. 58 (4): 1261-1270. epub 2010 december 01.
