Soil organic matter is widely recognized as a strategy used to improve soil quality and reduce carbon emissions to the atmosphere. A field study was carried out to investigate the effects of cover crops in organic no-till vegetables systems on changes in soil organic matter and CO2single bondC emissions, in dry and rainy seasons. We hypothesized that CO2single bondC emissions are higher in conventional till as compared with no-till, and that no-till increases soil C sink. The crop rotation comprised a 3-year cropping sequence involving two crops per year?cabbage (Brassica oleracea L.) in winter and eggplant (Solanum melongena L.) in summer time. Treatments were no-till on dead mulch of grass (Avena strigosa Schreb. and Zea mays L.), leguminous (Lupinus albus L. and Crotalaria juncea L.), intercrop (grass and leguminous) and conventional till (no dead mulch) with rotary hoe arranged in a randomized block design on a clayey Oxisol (Typic Haplustox) at Domingos Martins-ES, Brazil. On 2012 and 2013, disturbed soil samples at three different layers (0?5, 5?15 and 15?30 cm) and undisturbed samples at 0?10, 10?20 and 20?30 cm, for chemical and organic matter characterization were taken. CO2single bondC emissions and soil temperature were measured in situ on March, May, August and October 2012 and February 2013 (after 3 years of experiment). Conventional till site showed the lowest microporosity values and the highest macroporosity, followed by lower soil bulk density at 0?10 cm layer. Total organic C ranged from 34.94 to 50.48 g kg?1 in intercrop and 27.11 to 43.74 g kg?1 in conventional till. Total N ranged from 2.81 to 5.34 g kg?1 in grass and 2.54 to 4.51 g kg?1 in conventional till. Highest C stock was recorded in intercrop. Conventional till showed lower labile C values while recalcitrant C was higher in the intercrop treatment. The annual average of CO2single bondC emissions (?mol CO2 m?2 s?1) followed the order: grass (15.89) > intercrop (13.77) > leguminous (13.09) > conventional till (11.20). Highest annual average of soil temperature was recorded in conventional till (23.95 °C). Lowest annual mean of soil water content, microbial biomass C, and highest metabolic quotient were recorded in conventional till. These results suggest that the use of cover crops and organic compost in pre-planting promote C increments. The contribution of organic residues increases the water holding capacity and reduces soil temperature. No-till reduces soil disturbance and promotes a positive balance of C. Organic no-till vegetable systems is a strategy to increase soil C and should be encouraged in order to increase soil quality in the Atlantic Forest Biome in Brazil.

A produção atual da pesca extrativista mundial é de cerca de 85 milhões de toneladas e apresenta uma queda de cerca de 1% ao ano na última década. O estabelecimento de estratégias que minimizem os impactos sobre os recursos pesqueiros de interesse comercial é fundamental e a piscicultura marinha com espécies autóctones pode contribuir nesta premissa conservacionista. A piscicultura marinha é um ramo pouco desenvolvido no Brasil e estudos com espécies aptas aos cultivos são importantes para promover diversificação. Uma importante ferramenta de pesquisa e extensão é a unidade de observação, que visa desenvolver e adaptar sistemas de produção. Para avaliar a adaptabilidade de espécies de peixes marinhos autóctones e gerar alternativas socioeconômicas e ambientais foi implantada uma Unidade de Observação de Cultivo de Peixes Marinhos ? UOPEM em Lajinha, distrito de Santa Cruz, Aracruz, ES, Brasil, por 18 meses. É composta de três tanques-rede cilíndricos de 8 m de diâmetro, cada um contendo um tanque berçário de 6 m3 com malha de 10 mm, gaiola com malha de 40 mm, profundidade de 4 m e volume de 200m3. Foram realizados esforços de captura de peixes autóctones utilizando-se de tarrafa em batera de madeira a remo no período noturno com lua nova e maré 0,0, porém com pouco êxito, mas peixes não capturados penetraram e cresceram na UOPEM. Foram realizadas biometrias sazonais e a partir dos dados biométricos, foi calculada a Taxa de crescimento específico (TCE). Os sargos-de-dentes Archosargus probatocephalus, os vermelhos Lutjanus jocu e os parus brancos Chaetodipterus faber apresentaram as melhores taxas de crescimento específico e também apresentaram os maiores exemplares capturados (1,4 e 790 g, 1,1 e 800 g e 1,1 e 560 g, respectivamente), o que demonstra serem espécies potenciais para os cultivos.
As carapebas Eugerres brasilianus foram os peixes mais abundantes na comunidade inicial (44%), mas apresentaram menor taxa de crescimento específico (TCE = 0,9) e baixa sobrevivência, provavelmente porque foram predadas pelas outras espécies. The current production of extractive fishing worldwide is around 85 million tons and has fallen by about 1% per year for the past decade. The establishment of strategies that minimize the impacts on fishery resources of commercial interest is essential and marine fish farming with native species can contribute to this conservationist premise. Marine fish farming is a poorly developed in Brazil and studies with species suitable for cultivation are important to promote diversification. An important research and extension tool is the observation unit, which aims to develop and adapt production systems. To evaluate the adaptability of native marine fish species and to generate socioeconomic and environmental alternatives, a Marine Fish Rearing Culture Observation Unit - UOPEM was implemented in Lajinha, Santa Cruz district, Aracruz, ES, Brazil, for 18 months. It consists of three cylindrical jails of 8 m in diameter, each containing a 6 m3 nursery tank with a 10 mm mesh, a 40 mm mesh cage, a depth of 4 m and a volume of 200 m3. Efforts were made to capture native fish using a fishing net in a wooden boat at night with new moon and tide 0.0, but with little success, but uncaught fishes penetrated and have grown at UOPEM. Seasonal biometrics were performed and from the biometric data, the specific growth rate (SGR) was calculated. The sheepshead bream Archosargus probatocephalus, the dog snapper Lutjanus jocu and the angelfish Chaetodipterus faber had the best specific growth rates and also had the largest specimens captured (1.4 and 790 g, 1.1 and 800 g and 1.1 and 560 g, respectively), which shows that they are potential species for rearing culture. Brazilian mojarra Eugerres brasilianus were the most abundant fish in the initial community (44%), but they presented a lower specific growth rate (SGR = 0.9) and a low survival, probably because they were preyed upon by other species.
