Metodologia: Trata-se de um estudo qualitativo, de caráter exploratório, realizado em uma comunidade de pescadores localizada em Maceió, capital do estado de Alagoas, região Nordeste do Brasil. A aproximação ao campo de pesquisa se deu através da técnica snowball que resultou em um total de oito participantes. Para produção dos dados usou-se um roteiro de entrevista semiestruturado, elaborado pelos pesquisadores, contemplando questões acerca da organização da vida cotidiana dos participantes antes e após o processo de desocupação.

Methodology:This case-control observational study was conducted in the department of neurology and medicine, DMCH from May 2010 to April 2011 for a duration of 1 year. The study included purposively selected 80 persons. Patients attending the outdoor and admitted in indoor of department of neurology and medicine, DMCH with a clinically suspected CTS and established by electrophysiological parameters selected as cases (group –I) . Healthy volunteers and subjects who were devoid of any features of CTS but having history with isolated injury to the lower limb nerve and isolated facial nerve palsy with normal electrophysiological parameters selected as control (group –II). Data were collected by interview of the patients, clinical examination and laboratory investigations using the research instrument. Result: The mean age was 42.7±9.8 years with range from 24 to 64 years and 41.1±9.1 years with range...

The average number of eggs per sac was 161.5; the average egg diameter was 22 mm. The spiders were monitored in the laboratory to determine the inter-instar rate of growth. Eggs held in parafrin and carboxymethyl-cellulose developed only to gastrula. Under laboratory conditions, spiders did not build complete egg sacs, and the eggs were eaten. Several egg sacs were destroyed by fungus and parasitoids. The time of emergence of the spiderlings after oviposition was between 23 and 27 days. The reproduction period occurred between April and October and was apparently related to rain and relative humidity. The spiders have little parental care of the eggs and spiderlings. RESUMEN. De los 50 ejemplares de Linothele megatheloides (Raven), creciendo bajo condiciones de labo? ratorio, solamente 22 llegaron a la madurez sexual, luego de entre 10 y 11 mudas. Las aranas se monitoriaron en el laboratorio para determinar el incremento entre un instar y el proximo. Los huevos incluidos en parafina liquida y en carboximetil celulosa, solamente llegaron a gastrula. Bajo condiciones de laboratorio, las aranas no construyeron la ooteca completa y sus huevos eran normalmente comidos por ella. Varios sacos de huevos fueron parasitados y destruidos por hongos y parasitoides. El tiempo de emergencia de las aranitas luego de ser puesta la ooteca estuvo entre 23 y 27 dias. El periodo de reproduction estuvo entre abril y octubre, situation aparentemente relacionada con el incremento en humedad relativa. Las aranitas no mostraron inversion parental alta con sus huevos y crias.

O experimento foi conduzido no campo experimental da Universidade Estadual de Mato Grosso do Sul (UEMS), município de Glória de Dourados, em solo classificado como Argissolo Vermelho, textura arenosa. O delineamento experimental utilizado foi de blocos casualizados com seis tratamentos e quatro repetições. Os tratamentos constaram dos seguintes arranjos: monocultivo de milho, milho consorciado com feijão-de-porco (Canavalia ensiformis), milho consorciado com crotalária (Crotalaria juncea), milho consorciado com mucunapreta (Stylozobium aterrimum), milho consorciado com guandu-anão (Cajanus cajan) e milho consorciado com feijão-caupi (Vigna unguiculata). O milho consorciado com crotalária-júncea apresentou maior produtividade em relação ao monocultivo de milho.

However, some occasional hermaphrodites specimens can be found. A histological description of two (among 179) hermaphrodites of the marine mussel Perumytilus purpuratus (Lamarck, 1819) that were collected in San Jorge Bay (24ºS) is given. The low proportion of hermaphrodites suggests that P. purpuratus hermaphroditism could be an accidental phenomenon; nevertheless other causes are also discussed in the present study.

Durante 57 días se comparó el crecimiento y sobreviviencia de pulpos juveniles Octopus mimus del norte de Chile alimentados con tres diferentes dietas: dos dietas húmedas (A y B) aglutinadas con solución de gelatina embutidas en tripa de cordero y una dieta control (C) natural. La dieta (A) fue elaborada en base a una mezcla de filete triturado del pescado Cheilodactylus variegatus con harina de pellet para salmón, la dieta (B) con pasta de almeja (Protothaca thaca) mezclada con filete de Ch. variegatus y la dieta control consistió en el suministro de almejas frescas congeladas (C). Basado en un diseño experimental de medidas repetidas, los pulpos se mantuvieron individualmente en estanques de 70 L con circulación de agua de mar y aireación permanente. Los pulpos que consumieron la dieta B no experimentaron mortalidad y la dieta control C presentó mortalidad del 16,7%, sus crecimiento fueron similares (P > 0,05) con tasas de crecimiento absoluta (AGR) de 7,0 ± 0,91 (g d-1) y 6,6 ± 1,10 (g d-1) respectivamente. Los pulpos alimentados con la dieta A registraron mortalidad de 33,3% y tasa de crecimiento absoluta negativa, AGR=-1,70 ± 0,37 (g d-1). La dieta A que contenía como ingrediente pellet para salmón molido como harina no tuvo una adecuada aceptación y los ejemplares experimentaron disminución de su peso. La dieta B preparada con gelatina de origen animal como aglutinante, no implicó un efecto negativo en la palatabilidad y aceptabilidad en comparación al control basada en almeja fresca congelada, incluso los organismos lograron crecimientos similares. Los resultados permitirán a futuro mejorar la calidad nutricional de dietas artificiales para maximizar el crecimiento de O. mimus en cautiverio. Palabras clave: Octopus mimus, crecimiento, dieta, embutido, cautiverio, norte de Chile. Growth evaluation of octopus (Octopus mimus) from northern Chile fed with formulated diets ABSTRACT. The growth and survival of juvenile octopus, Octopus mimus, from northern Chile, fed three different diets were analyze during 57 days. Two of the diets (A and B) were wet diets stuffed in lamb gut with a gelatin solution, and the third (C) was a natural control. Diet (A) was a mixture of chopped fish meat (Cheilodactylus variegatus) and pellets of salmon meal; diet B was made up of clam (Protothaca thaca) mixed with C. variegatus meat; and diet (C) (control) consisted of fresh frozen clams. The experimental design was based on repetitive measures; the octopuses were supported individually 70-L tanks, with constant sea water circulation and aeration. The octopuses fed diet B did not registred mortality, whereas those fed the control (diet C) presented a mortality of 16.7%. Growth rates were similar (P > 0.05) for these two groups, with absolute growth rates (AGR) of 7.0 ± 0.91 (g d-1) and 6.6 ± 1.10 (g d-1), respectively. The octopuses fed diet A had a mortality of 33.3% and an AGR of-1.70 ± 0.37 (g d-1). Diet A, which contained pellets of ground salmon meal, was not well-accepted, and the weight of the octopuses in this group declined. Diet B, prepared with gelatin from animal origins, was no less palatable or acceptable than the control diet of fresh frozen clams, and the individuals in these two groups showed similar growth. These results will allow us to improve the nutritional quality of artificial diets in order to maximize the growth of O. mimus in captivity.
