| Este trabalho tem o objetivo de determinar quais foram as fontes de crescimento da produção agrícola no Estado de São Paulo entre 1990 e 2005. Para essa análise utilizou-se o modelo econométrico denominado “shift-share”, também conhecido como estrutural-diferencial. A análise foi dividida em subperíodos, tendo como objetivo abordar o comportamento da produção agrícola em diversos momentos da economia brasileira. Os fatores que explicam a evolução da produção nos subperíodos determinados foram os efeitos área, rendimento e localização geográfica. As alterações na área cultivada por sua vez foram subdivididas em efeito escala e substituição. A mandioca foi a cultura que apresentou maior crescimento da produção agrícola entre 1990 e 1995, o que se deu em... |

| Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting flat oysters Ostrea edulis. The parasite has been described in different ecosystems from estuaries to open sea and no clear correlations could be demonstrated between the development of the disease and environmental parameters such as temperature or salinity. The parasite life cycle, including its survival outside the host is not completely known. Nevertheless, the infection can be directly transmitted by cohabitation between infected and non infected oysters suggesting that the parasite does not need intermediate host to complete its cycle. In the present study, the impact of temperature and salinity on the survival of purified parasites... |

| Although individual electronic tagging using passive integrated acoustic (PIT) tags is established, it is mainly for fish >60. mm in length and is unsuitable for fish of <30. mm, like zebrafish. We used radio frequency identification (RFID) microtags (1 mm in diameter and 6 mm in length, with a mass of similar to 10 mg) to individually identify juvenile zebrafish (length 16-42 mm, mass 138-776 mg) for the first time, and studied the effects of intracoelomic implantation on fish survival and microtag loss, growth, spawning and exploratory behaviour. After 5.5 months, both high survival (82%) and low microtag loss (11%) were achieved. The smallest surviving fish weighed 178 mg, and success in microtag reading was 73% for the size class 350-450 mg (26... |

| Interactions between distant places are increasingly widespread and influential, often leading to unexpected outcomes with profound implications for sustainability. Numerous sustainability studies have been conducted within a particular place with little attention to the impacts of distant interactions on sustainability in multiple places. Although distant forces have been studied, they are usually treated as exogenous variables and feedbacks have rarely been considered. To understand and integrate various distant interactions better, we propose an integrated framework based on telecoupling, an umbrella concept that refers to socioeconomic and environmental interactions over distances. The concept of telecoupling is a logical extension of research on... |

| Fusarium head blight is an important disease affecting cereal grains. Fusarium graminearum is the major causal agent of this disease around the world, but some researchers have documented the increased importance of F. poae. Moreover, F. poae presence may be accompanied of its mycotoxins production, being able to produce trichothecenes of type A diacetoxyscirpenol, monoacetoxyscirpenol, scirpentriol, HT-2 toxin, T-2 toxin and neosolaniol, as well as the type B nivalenol and fusarenone-X. Outside the trichotecenes group, F. poae has been reported to produce enniatins, beauvericin and moniliformin. Due to F. poae may be present in cereal grains used for food and processed products, the aims of this review is to recognize the importance of the hazard effects... |

| The risk posed by complex chemical mixtures in the environment to wildlife and humans is increasingly debated, but has been rarely tested under environmentally relevant scenarios. To address this issue, two mixtures of 14 or 19 substances of concern (pesticides, pharmaceuticals, heavy metals, polyaromatic hydrocarbons, a surfactant, and a plasticizer), each present at its safety limit concentration imposed by the European legislation, were prepared and tested for their toxic effects. The effects of the mixtures were assessed in 35 bioassays, based on 11 organisms representing different trophic levels. A consortium of 16 laboratories was involved in performing the bioassays. The mixtures elicited quantifiable toxic effects on some of the test systems... |
