| Over the past century, regional fisheries for Pacific salmon (Oncorhynchus spp.) have been managed primarily for their provisioning function, not for ecological support and cultural significance. We examine the resilience of the regional salmon fisheries of Japan, the Russian Far East, Alaska, British Columbia, and Washington-Oregon-California (WOC) in terms of their provisioning function. Using the three dimensions of the adaptive cycle—capital, connectedness, and resilience—we infer the resilience of the five fisheries based on a qualitative assessment of capital accumulation and connectedness at the regional scale. In our assessment, we evaluate natural capital and connectedness and constructed capital and connectedness. The Russian... |

| River ecologists are also river-basin planners. However, their role in planning has developed slowly over the decades since the beginning of the 20th century. Three major factors explain this phenomenon. First, ecologists focused on plant and animal communities rather than on broader policy issues related to land settlement and water development. Second, the federal government, and most state and local governments as well, used mainly economic criteria to justify projects. Intangible benefits, including the value of species or an aesthetically pleasing landscape, drew relatively little attention. Third, the public generally favored development, especially during the Great Depression of the 1930s. Only after World War II did the public's position shift in... |

| Apresenta-se neste trabalho um breve histórico dos registros genealógicos, com referencia a sua importância para o melhoramento genético animal. Ênfase especial e dada para o caso das raças zebuínas, criadas no Brasil. Em decorrência do fechamento do livro de registro; ocorrido em 1971 para a maioria das raças, e, em função de problemas conjunturais ocorridos desde então, e grande, atualmente, o contingente de animais que se encontra a margem do controle oficial. Por outro lado, os rebanhos considerados puros não conseguem suprir sequer a metade da demanda anual de reprodutores, necessária para a reposição nos planteis de seleção e nos rebanhos comerciais. Com base na analise e discussão de aspectos práticos, genéticos, econômicos e políticos, apresenta-se... |
