The lack of standardization of bioassays for the evaluation of toxic baittoxicity on the South American fruit fly,Anastrepha fraterculus(Weidemann 1830), has led to erroneous interpretations of assay results.The objective of this study was to develop a methodology for the stan-dardization and validation of toxicological tests onA. fraterculustoxic baitusing the Success?0.02CB formulation (80 mg L−1of spinosad).Anastrepha fraterculusadults, obtained from larvae reared on an artificialdiet, showed higher susceptibility (LT50= 48.96 h) than adults from larvaereared on cattley guava (LT50= 53.83 h) and mango fruit (LT50= 53.55 h).Anastrepha fraterculusadults at the age of five (LT50= 65.30 h), 15 (LT50=59.01 h), and 30 (LT50= 55.53 h) days presented... |

The challenge confronting those seeking to understand the institutional dimensions of global environmental change and patterns of land-use and land-cover change is to find effective methods for analyzing the dynamics of socio-ecological systems. Such systems exhibit a number of characteristics that pose problems for the most commonly used statistical techniques and may require additional and innovative analytic tools. This article explores options available to researchers working in this field and recommends a strategy for achieving scientific progress. Statistical procedures developed in other fields of study are often helpful in addressing challenges arising in research into global change. Accordingly, we start with an assessment of some of the enhanced... |

Scholars of comanagement are faced with a difficult methodological challenge. As comanagement has evolved and diversified it has increasingly merged with the field of adaptive management and related concepts that derive from resilience thinking and complex adaptive systems theory. In addition to earlier considerations of power sharing, institution building, and trust, the adaptive turn in comanagement has brought attention to the process of social learning and a focus on concepts such as scale, self-organization, and system trajectory. At the same time, a number of scholars are calling for a more integrated approach to studying (adaptive) comanagement that is able to situate these normative concepts within a critical understanding of how context and power... |

Registros de produção de leite de 19.151 lactações de 8.984 vacas, filhas de 795 touros Gir, foram usados para avaliar geneticamente as vacas. Equação de modelo misto foi usada para predizer o valor genético dos touros que foram incorporados no índice de seleção das vacas. Além do índice de seleção, os modelos animais foram também usados para predizer o valor genético das vacas, usando somente a primeira lactação ou até cinco lactações por vaca. As confiabilidades das predições obtidas dos valores genéticos das vacas usando-se os modelos animais foram maiores, quando foram usadas na avaliação até cinco lactações (0,76) ou somente a primeira lactação (0,73), em relação às confiabilidades das predições obtidas pelos índices de seleção (0,55 a 0,59).... |

Este trabajo se relaciona con los senderos como elementos para transcurrir a través de un paisaje determinado. Al recorrerlos, se aprecia e interpreta lo que se ve, se oye, se huele, se palpa e incluso, lo que se degusta. Este trabajo analiza los senderos de forma integral, por lo que en éste se encuentra información de paisaje, arquitectura de paisaje, escala, y turismo, entre otros aspectos relevantes. Se expone también aquí, una aproximación metodológica para el diseño y construcción de senderos a partir de la disciplina de la arquitectura de paisaje. En este trabajo se parte de los siguientes objetivos: a) conocer, revisar y proponer metodologías aplicables al diseño de senderos desde de la arquitectura de paisaje; b) plantear una aproximación... |

En septembre 1984, MM. HERAL et DESLOUS-PAOLI organisèrent à La Tremblade, une "réunion méthodologie expérimentale mollusques". Cette rencontre faisait suite à un bref état qui s'était engagé au Congrès de Montpellier sur les "Bases biologiques de l'Aquaculture", où il était apparu que la terminologie et la méthodologie concernant le métabolisme des bivalves devaient être clarifiées. Grâce à une large information auprès des spécialistes français de la physiologie des bivalves, la réunion à La Tremblade a réuni un grand nombre de participants très motivés. Pendant 2 jours des discussions très animées ont permis de bien comprendre les échanges entre les bivalves et leur environnement et d'y jeter un regard neuf, ce qui impliquait une analyse critique du... |

The development of appropriate methodologies for bioassays is of paramount importance to study the methodological factors that may interfere in the experimental design. Thus, laboratory bioassays have become increasingly important for the determination of data that are realistic and replicable. The objective of the study was to develop a bioassay methodology with the ready-to-use toxic bait Success ? 0.02CB, 96 mg L−1 of spinosad, in adults of Ceratitis capitata (Wiedemann) as a study model. The insect origin laboratory population, LT 50= 11.16 h), time of toxic bait supply (4 h, LT 50= 16.85 h), food deprivation (12 h, LT 50= 15.55 h), and the adult age (5 days, LT 50= 35.31 h) of C. capitata showed higher susceptibility and a shorter LT 50... |

Los moluscos bivalvos son organismos sedentarios que establecen una relación íntima no sólo entre ellos, sino también con el espacio que ocupan y con sus condiciones fisicoquímicas. Sus poblaciones pueden ser hospedadoras de múltiples organismos patógenos (virus,bacterias, hongos, protistas y metazoos), cuya presencia es regulada eficazmente a niveles infra, meta y suprapoblacionales en ambientes silvestres, no provocando, salvo excepcionalmente, impactos severos. Los cultivos a escala comercial producen concentraciones de individuos, con la consiguiente alteración del medio y del equilibrio natural en la relación parásito-hospedador, generándose condiciones apropiadas para el desarrollo de enfermedades. Entre los años 1995 y 1996 se instala, en la zona... |

Competing claims on natural resources become increasingly acute, with the poor being most vulnerable to adverse outcomes of such competition. A major challenge for science and policy is to progress from facilitating univocal use to guiding stakeholders in dealing with potentially conflicting uses of natural resources. The development of novel, more equitable, management options that reduce rural poverty is key to achieving sustainable use of natural resources and the resolution of conflicts over them. Here, we describe an interdisciplinary and interactive approach for: (i) the understanding of competing claims and stakeholder objectives; (ii) the identification of alternative resource use options, and (iii) the scientific support to negotiation processes... |

Secondary crops are of increasing interest to policymakers and planners in developing countries because of a desire to diversify economic activities and because of their proven potential to raise farm incomes and rural employment. To assess this potential, basic information on the demand characteristics for these crops is required. But, given the large number of possible crops to be studied, policy analysts require an estimation procedure that is less data-intensive and time-intensive than standard econometric estimation procedures. In this paper, a relatively new, low-cost procedure, based on demand for food characteristics, is applied, illustrating its usefulness for analysis of demand for potatoes in Bangladesh and Pakistan. In Asia, the potato should... |
