| A comunidade de plantas visitadas por abelhas foi estudada em um fragmento de 8,2 ha na Área de Proteção Ambiental das Lagoas e Dunas de Abaeté, Salvador, Bahia (12º56 S e 38º21 W). Entre janeiro e dezembro de 1996, três vezes ao mês, as plantas floridas eram amostradas, registrando-se para cada espécie o período de floração, hábito e características florais como: cor, forma, sexualidade, simetria, deiscência das anteras e recurso oferecido ao visitante. O tipo de vegetação local é a restinga, composta principalmente por arbustos e subarbustos. Foram observadas 97 espécies vegetais e a família Fabaceae foi a mais rica em número de espécies. Das espécies observadas, 66 foram visitadas por abelhas, sendo que 12 delas foram predominantemente visitadas... |

| Bivalve haemocytes are essential in defence mechanisms including phagocytosis. They also produce molecules including hydrolytic enzymes and antimicrobial peptides that contribute to pathogen destruction. Although haemocyte activities have been extensively studied, relatively little is known about the intracellular signalling pathways that are evoked during haemocyte activation and especially the role of calcium. Flow cytometry has been used for the first time to define the effect of cell incubation in haemolymph and artificial sea water (ASW) on Pacific oyster, Crassostrea gigas, haemocytes. Cell viability, enzymatic activities (esterases and amino peptidases), phagocytosis and granulocyte percentage were analysed. Viability and some activities were... |

| Two organic systems were studied, the first based on self-sufficiency (SS) and the feeding of high-forage diets, and the second on purchased concentrates (PC) and maximising milk output. The growing of both concentrate and forage feeds in the SS system reduced the stocking density. Feeding high-forage diets increased the proportion of milk produced from forage but decreased the energy concentration of the ration, leading to lower milk persistency, reduced milk protein in early lactation and reduced pregnancy rates. In the PC system importing feed increased the stocking density but also increased the ‘farm-gate’ nutrient surpluses. |

| The framework allows comprehensive and consistent measurement and classification of U.S. domestic support to 2015 under different assumptions. Projections of future U.S. domestic support patterns are made with estimates published in the USDA Agricultural Baseline Projections. We also use information from the OECD, FAPRI, NASS, and our own estimates. We present key elements and an overview of our analytical framework, assumptions of a baseline scenario, and some analytical results and observations arising from our analysis. The baseline scenario extends the classification of programs in WTO notifications to 2015. The framework consists of 65 spreadsheets, which are grouped into 4 analytical stages: calculation of program estimates by commodity; calculation... |

| Nowadays many developing countries focus on economic policies for promoting international tourism and exports expansion as a potential source of economic growth of the country. However, the understanding of the relationship between exports and economic growth is still ongoing. When treating the relationship between tourism and economic growth, considering tourism as a non-traditional export few studies have been published to date. This paper has the objective to assess if exports and tourism have really promoted growth by means of the export-led growth hypothesis (ELGH) and the tourism-led growth hypothesis (TLGH). The cases under analysis are Spain and Italy, two of the most important countries worldwide regarding the expansion of tourism. Cointegration... |

| The Dead Sea basin plays a major role for regional economic development (industry, tourism and agriculture) in the Middle East. This potential is threatened by the steady disappearance of the Dead Sea. Since around 1930 the water level of the Dead Sea has fallen by about 25 m, about half of this alone in the last 20 years. The Dead Sea is a transboundary resource shared by Israel, the Palestinian Authority and Jordan. The Dead Sea is the terminal point of the Jordan River watershed and as such, it serves as a barometer for the health of the overall system. Its rapid decline reflects the present water management strategies of the riparian and upstream countries. This includes the different water cultures of the three countries. Throughout history, the Dead... |

| The regulatory approval of genetically modified crops in the field initially requires small, restricted experimental trials known as confined field trials. These small scale experiments provide researchers with important information on environmental interactions and agronomic performance of the crop in a safe and contained manner. To authorize confined field trials regulatory review is required, with formats for obtaining relevant information differing from country to country. In this paper, a Gap Analysis is used to identify informational gaps and potential for harmonization of confined field trial application processes in three East African countries - Tanzania, Kenya, and Uganda. The basic principle behind gap analysis is a comparison of the status quo... |

| This paper is a work-in-progress account of ideas and propositions about resilience in social-ecological systems. It articulates our understanding of how these complex systems change and what determines their ability to absorb disturbances in either their ecological or their social domains. We call them “propositions” because, although they are useful in helping us understand and compare different social-ecological systems, they are not sufficiently well defined to be considered formal hypotheses. These propositions were developed in two workshops, in 2003 and 2004, in which participants compared the dynamics of 15 case studies in a wide range of regions around the world. The propositions raise many questions, and we present a list of... |
