| In 1982 Dominga Cavallo and Yair Mundlak received an award for quality of research discovery from the American Agriculture Economics Association for IFPRI Research Report 36, Agriculture and Economic Growth in an Open Economy: The Case of Argentina. The research was sponsored jointly by IFPRI and the Instituto de Estudios Economicos Sobre la Realidad Argentina y Latinoamericana (IEERAL) of the Fundacion Mediteranea, and it in turn built on earlier prize-winning research by Mundlak, presented in Research Report 6, Intersectoral Factor Mobility and Agricultural Growth. The model developed for the study makes it possible to explore the effects of policies directed at agriculture as well as general macro and trade policies, taking into account interaction... |

| Dentre os jardins criados pelo homem, destaca-se o jardim botânico, que possui diversas funções: científica, educacional, social, estética, histórica e ecológica. O atual Jardim Botânico de São Paulo, fundado oficialmente em 1938, apresenta todas essas funções, mas o registro de sua história carecia de revisão e atualização. A história do Jardim Botânico está repleta de tentativas frustradas de implantação e de mudanças de local de instalação, sendo os dois mais importantes na sua história: o local que abrigou o primeiro Jardim Botânico de São Paulo, entre 1799 e 1838, onde está atualmente o Parque da Luz, e o local onde está desde 1928, no Parque Estadual das Fontes do Ipiranga (PEFI). Outros jardins botânicos de São Paulo no período de 1896 a 1928 foram:... |

| ABSTRACT The yellow-tailed woolly monkey, Lagothrix flavicauda (Humboldt, 1812), is a large atelid endemic to the cloud forests of Peru. The identity of this species was uncertain for at least 150 years, since its original description in 1812 without a voucher specimen. Additionally, the absence of expeditions to the remote Peruvian cloud forests made it impossible to collect material that would help to confirm the true identity of L. flavicauda during the 19th and first half of the 20th century. Until now, the specimens of L. flavicauda collected by H. Watkins, in 1925, in La Lejía (Amazonas, Peru) were thought to be the oldest ones deposited in any scientific collection. Nevertheless, after reviewing the databases of the several international museums and... |

| It has been argued that the study of natural selection and quantitative genetics should have a central role in evolutionary thinking and undergraduate teaching in Chile. Extensive operational use of the concept of natural selection may seem consistent with this argument. However, advances of evolutionary knowledge in independent fields such as phylogenetic analysis, developmental evolution, and paleontology cannot be ignored. I argue here that the role of natural selection in contemporary evolutionary biology can be compared to that of Newtonian mechanics in contemporary physics: it can describe a given domain of observations, but it is insufficient to handle the different sources of evolutionary knowledge. Overemphasis on natural selection as the... |

| The expression "Integrated Pest Management" (IPM or MIP in Portuguese) is completing 28 years since it first appeared in press. Since then integrated pest management or integrated pest control has become the paradigm of choice for activities that aim at attenuating the impact of all pests - plant diseases, weeds, and invertebrate or vertebrate animals - in agricultural production, in human and animal health, and in urban or rural structures. Despite the nearly universal acceptance of the concept, its practical application still is rather restricted, varying considerably among geopolitical regions, the nature of the crop, and, mainly, with the commitment and support of responsible governmental entities for programs dedicated to promote adoption of IPM. An... |
