Results show that the development of land use is strongly related to land distribution structure. While large farms have increased their share of annual and perennial crops, small and medium size farms have strongly contributed to the development of beef and milk market chains in both Rondônia and Mato Grosso. Land use intensification has occurred in the form of increased use of machinery, labor in agriculture and stocking rates of cattle herds.

    Epidemiological Update Yellow Fever 10 July 2017 Situation summary in the Americas From epidemiological week (EW) 1 to EW 26 of 2017, Brazil, Colombia, Ecuador, Peru, the Plurinational State of Bolivia, and Suriname have reported suspected and confirmed yellow fever cases. The following is an update on the situation in Brazil, the Plurinational State of Bolivia, Ecuador, and Peru. No changes in the number of reported cases have been reported in the other countries. In Brazil, since the beginning of the outbreak in December 2016 up to 31 May 2017, there were 3,240 suspected cases of yellow fever reported (792 confirmed, 1,929 discarded, and 519 under investigation), including 435 deaths (274 confirmed, 124 discarded, and 37 under investigation). The case fatality rate (CFR) among confirmed cases is 35%. According to the probable site of infection,1 suspected cases correspond to 407 municipalities, while the confirmed cases were distributed among 130 municipalities in 8 states (Espírito Santo, Goiás, Mato Grosso, Minas Gerais, Pará, Rio de Janeiro, São Paulo, and Tocantins) and the Federal District. With regard to the confirmed fatal cases and their probable site of infection, one corresponds to the Federal District, 85 to Espírito Santo, one to Goiás, one to Matto Grosso, 165 to Minas Gerais, four to Pará, 7 to Rio de Janeiro, and 10 to São Paulo. In the states with more than 5 confirmed deaths, the CFR among confirmed cases is 50% in São Paulo, 41% in Rio de Janeiro, 34% in Minas Gerais, and 33% in Espírito Santo. No cases were confirmed in new municipalities in Espírito Santo (ES), Minas Gerais (MG), São Paulo (SP), and Rio de Janeiro (RJ) in the last month.

  • Convergent Agrarian Frontiers in the Settlement of Mato Grosso, Brazil
    Convergent Agrarian Frontiers in the Settlement of Mato Grosso, Brazil Lisa Rausch University of Wisconsin-Madison Nelson Institute for Environmental Studies Abstract: The heterogeneity of development in the contemporary southern Amazon may be linked to different settlement experiences on the frontier. Three main types of productive settlement have been identified, including official colonization, private colonization, and spontaneous settlement, based on the differentiated motivations and resources of participants in these settlements. Not only did these different types of frontiers advance concurrently in the Amazon, but these frontiers sometimes converged in one location. The interaction of settlers from different groups sometimes created conflict, but also advanced the process of territorialization of the Amazon. This position is illustrated via a case study of one municipality at which three groups of settlers converged. Ultimately, though local popular history privileges the role of one of the three groups in bringing about the founding of the municipality and the development of a successful local economy, these achievements were only possible due to the different resources that each group brought to the settlement. Introduction he heterogeneity of the Brazilian Amazon frontier experience is just beginning to be understood. Early researchers set out structuralist expectations of accelerating resource Texploitation, capital accumulation by a relative few as land holdings were systematically consolidated, and the enlistment of the peasantry into wage labor as the agricultural frontier advanced into the Amazon.1 A linear progression toward the homogenization of Amazonian places has not occurred, however, even as highly capitalized industrial agriculture has continued to advance in the region.2 Today, the Amazon is a tapestry of highly globalized and globalizing cities, relic frontier towns, marginal extractive landscapes, and panoramas of modern, industrial- scale agricultural production with a range of landholding sizes.

  • Digit Evolution in Gymnophthalmid Lizards JULIANA G
    Int. J. Dev. Biol. 58: 895-908 (2014) doi: 10.1387/ijdb.140255jg www.intjdevbiol.com Digit evolution in gymnophthalmid lizards JULIANA G. ROSCITO*,1, PEDRO M.S. NUNES2 and MIGUEL T. RODRIGUES1 1Departamento de Zoologia, Instituto de Biociências, Universidade de São Paulo-SP and 2Departamento de Zoologia, Centro de Ciências Biológicas, Universidade Federal de Pernambuco, Brazil ABSTRACT The tetrapod limb is a highly diverse structure, and reduction or loss of this structure accounts for many of the limb phenotypes observed within species. Squamate reptiles are one of the many tetrapod lineages in which the limbs have been greatly modified from the pentadactyl generalized pattern, including different degrees of reduction in the number of limb elements to complete limblessness. Even though limb reduction is widespread, the evolutionary and develop- mental mechanisms involved in the formation of reduced limb morphologies remains unclear. In this study, we present an overview of limb morphology within the microteiid lizard group Gymn- ophthalmidae, focusing on digit arrangement. We show that there are two major groups of limb- reduced gymnophthalmids. The first group is formed by lizard-like (and frequently pentadactyl) species, in which minor reductions (such as the loss of 1-2 phalanges mainly in digits I and V) are the rule; these morphologies generally correspond to those seen in other squamates. The second group is formed by species showing more drastic losses, which can include the absence of an ex- ternally distinct limb in adults. We also present the expression patterns of Sonic Hedgehog (Shh) in the greatly reduced fore and hindlimb of a serpentiform gymnophthalmid.

  • From Four Sites in Southern Amazonia, with A
    Bol. Mus. Para. Emílio Goeldi. Cienc. Nat., Belém, v. 4, n. 2, p. 99-118, maio-ago. 2009 Squamata (Reptilia) from four sites in southern Amazonia, with a biogeographic analysis of Amazonian lizards Squamata (Reptilia) de quatro localidades da Amazônia meridional, com uma análise biogeográfica dos lagartos amazônicos Teresa Cristina Sauer Avila-PiresI Laurie Joseph VittII Shawn Scott SartoriusIII Peter Andrew ZaniIV Abstract: We studied the squamate fauna from four sites in southern Amazonia of Brazil. We also summarized data on lizard faunas for nine other well-studied areas in Amazonia to make pairwise comparisons among sites. The Biogeographic Similarity Coefficient for each pair of sites was calculated and plotted against the geographic distance between the sites. A Parsimony Analysis of Endemicity was performed comparing all sites. A total of 114 species has been recorded in the four studied sites, of which 45 are lizards, three amphisbaenians, and 66 snakes. The two sites between the Xingu and Madeira rivers were the poorest in number of species, those in western Amazonia, between the Madeira and Juruá Rivers, were the richest. Biogeographic analyses corroborated the existence of a well-defined separation between a western and an eastern lizard fauna. The western fauna contains two groups, which occupy respectively the areas of endemism known as Napo (west) and Inambari (southwest). Relationships among these western localities varied, except between the two northernmost localities, Iquitos and Santa Cecilia, which grouped together in all five area cladograms obtained. No variation existed in the area cladogram between eastern Amazonia sites. The easternmost localities grouped with Guianan localities, and they all grouped with localities more to the west, south of the Amazon River.

  • Population Distribution and Environmental Change in Brazil's
    Population Distribution and Environmental Change in Brazil’s Center-West Region. Daniel Joseph Hogan, José Marcos Pinto da Cunha and Roberto Luiz do Carmo Population Studies Center – NEPO, State University of Campinas, 13081-970 Campinas, São Paulo, Brazil, [email protected] Introduction The major land use change underway in Brazil’s Center-West1 (2,129,010.7 km2, representing 24.9% of the country’s area – somewhat less than half the Amazon region), is the substitution of tropical humid forest on the region’s northern reaches (Amazon) and (especially) of the savanna-like cerrado. With a 2000 population of 14,144,534, the region has undergone rapid development over the last three decades. In this period, the region has moved from (1) a sparsely populated area of subsistence agriculture to (2) a major migration destination for land- seeking migrants from other regions to (3) dynamic export-oriented monoculture. This has been a rapid process, coinciding with the modernization of Brazilian agriculture; increasing mechanization and government incentives have contributed to the transformation of vast extensions of land to the production of grains (especially soybeans, but also cotton, corn and rice) and cattle-raising. Great expectations have been placed on an expanding world market for soybeans and Brazil’s comparative advantage in this field. While the Amazon forest has been recognized as an important resource to be conserved and sustainably managed2,thecerrado’s rich biodiversity and carbon storage (principally in root systems) have, until recently, been largely ignored. The transformation of the region into productive, high-tech agriculture has been seen as a victory of technology over nature.
