Some expected impacts of the Common Fishery Policy on marine food webs
Provedor de dados: 5
Autores: Kopp, Dorothee; Robert, Marianne; Chouvelon, Tiphaine; Mehault, Sonia.
For the ecosystem approach to fisheries management, understanding population dynamics and ecosystem resilience in response to the landing obligation acted by the reform of the European Common Fishery Policy (CFP) is currently an important avenue of research. This study attempts to assess the impact of the new CFP on marine food webs. Total carbon and nitrogen loss induced by a discard ban were estimated for the ecosystem of the Bay of Biscay based on French At-Sea Observer data and carbon and nitrogen content of discarded fish. Changes in predator diets were estimated by comparing two Bayesian mixing models, one mimicking the current situation and the second the application of the new CFP (removing the discarded species that would be landed from the...

ABSTRACT Irrigation is a limiting factor for the development of crops, and all water sources contain salts, which can accumulate in the soil and in the plant, compromising its development. The use of vermicompost is one of the alternatives to mitigate the negative effects of salts on plants. This organic compost is a soil conditioner and a nutrient source for plants. Thus, this study aimed to evaluate the growth and chorophyll of noni (Morinda citrifolia L.) in response to the salinity of irrigation water in substrates with and without vermicompost. A completely randomized design in a 4 × 3 factorial scheme was used, corresponding to four levels of electrical conductivity of the irrigation water (0.5, 1.5, 3.0 and 4.5 dS m-1), in three soil substrates...

ABSTRACT Strawberry is produced and appreciated in different regions of the world, due to its productive and commercial characteristics. Biofertilizer is an organic fertilizer that is easy to prepare and effective to nourish plants. The objective of this work was to assess the effect of different irrigation levels and anaerobically fermented bovine biofertilizer doses, on biomass accumulation and strawberry crop yield. The experiment was carried out in the experimental area of the UFC, in Fortaleza, Ceará, Brazil, from August to December 2012, under a screened environment. The experimental design was randomized blocks designed into subdivided plots, in which irrigation levels were applied via drip irrigation (equivalent to 33.3, 66.6, 100, 133.3 and 166.6%...

The impacts of biofertilizer and mineral fertilization on the growth and production of yellow passion fruit irrigated with moderately saline water
Provedor de dados: 118

Yellow passion fruit, because it is sensitive to the salinity of irrigation water or soil, requires restrictive water management strategies and inputs that mitigate the effects of salts on plants irrigated with harmful saline water levels. As such, an experiment was designed to evaluate the effects of bovine biofertilizer and mineral fertilization with NPK on the growth and production of yellow passion fruit plants irrigated with moderately saline water. Treatments were arranged in a randomized block with three replications and 12 plants per plot using a 4×2 factorial design with four doses of bovine biofertilizer diluted in water at 0, 33.3, 66.6 and 100% proportions in soil with and without NPK. The evaluated variables included the stem diameter, number...
