Mistletoes constitute an important food resource for animals in many ecosystems. However, these plants are considered pests in urban areas because of deleterious effects they have on the host trees. Studies in urban areas were mostly focused on listing host species or procedures to control the "pest". In this sense, broader studies including several aspects of mistletoes ecology in urban ecosystems are still missing. We studied the interaction of the mistletoe, Phoradendron affine, with its dispersers and hosts in two urban sites in Uberlandia, Brazil. Phoradendron affine fruits were consumed almost exclusively by Euphonia chlorotica, which was crucial for seed germination. Parasitism was recorded in five hosts, two native (Handroanthus chrysotrichus and Tabebuia roseoalba) and three exotic species (Spathodea campanulata, Ligustrum lucidum and Melia azedarach). Mistletoes were found parasitizing larger host trees, a trend commonly reported for mistletoe-host interaction. Mistletoe seed germination was not affected by the trees species, whether host or non-host, but the radicle of germinated seeds could not penetrate the bark and seedlings invariably died in non-host species. We found a high prevalence of parasitism in our study, in comparison to what previous studies reported for natural areas. The spatial distribution of the hosts and high light incidence on isolated host trees may lead to this high prevalence in urban areas. Rather than eradicated...

A histoplasmose, uma micose sistêmica, é um importante problema de saúde pública, de distribuição mundial e uma infecção muito comum em regiões endêmicas. A infecção é causada pelo fungo dimórfico Histoplasma capsulatum varo capsulatum, que cresce como fungo filamentoso em solo, guano de morcegos e aves, ou como uma levedura parasitária intracelular. A ocorrência de morcegos é relatada em quase todo o mundo e estes contribuem para manutenção deste fungo na natureza. Na cidade de São Paulo, Brasil, morcegos ocorrem em todas as regiões e em várias situações: usando sótãos e forro de telhado como abrigos ou adentrando residências, entre outras. Entre agosto de 2003 a dezembro de 2008, foram encaminhados ao Setor de Micologia do Centro de Controle de Zoonoses da cidade de São Paulo 2427 morcegos. Amostras de fígado e baço desses morcegos foram removidos em condições estéreis e inoculados, ambos, em Agar infusão de cérebro e coração (BHI) e em Agar Sabouraud Dextrose, incubados a 25°C e 37°C. As colônias suspeitas foram reincubadas em Agar Mycosel e identificadas pela morfologia e pela reversão em ML-gema (Mueller Hinton Broth com L-cisteína e gema de ovo) a 37°C. O objetivo deste estudo foi estabelecer a prevalência do H. capsulatum em morcegos presentes na cidade de São Paulo e em outras cidades do Estado. Os 87 isolados de H. capsulatum (3...

O objeto da presente tese é o desenvolvimento de uma proposta metodológica para planejamento energético no desenvolvimento de áreas urbanas, na escala de distritos, bairros e unidades de vizinhança. A metodologia proposta é aplicável a estudos de desenvolvimento de novas áreas urbanas, distritos ou bairros e estudos para requalificação de áreas urbanas já ocupadas, como ferramenta de suporte ao planejamento e ao processo decisório. Inicialmente, foi produzida uma base referencial dos principais condicionantes para o planejamento energético urbano, segundo o escopo considerado nesse trabalho de pesquisa. Nessa etapa foram identificadas e analisadas as interdependências entre esses fatores e sua participação no consumo energético e nas emissões de poluentes. A proposta metodológica está estruturada em dois módulos principais: Módulo 1 - Gerenciamento da Demanda de Energia, envolvendo aspectos relacionados à Morfologia Urbana, Mobilidade Urbana e Edificações, tais como densidade populacional e construída, uso e ocupação do solo, geometria de quadras e cânion urbano, sistema de transporte urbano de passageiros, sistema viário, tecnologias veiculares e combustíveis, soluções passivas em conforto ambiental e substituição tecnológica de equipamentos em edificações; e Módulo 2 - Gerenciamento da Oferta de Energia...

Airborne Laser Scanning is an established technique to produce Digital Terrain Models (DTM). In spite of its widespread use, the extraction of a DTM in urban areas still poses problems because the filtering process often fails to separate some of the objects on the terrain surface from the terrain itself. This happens because only one kind of information – geometric information – is used in the process. To overcome this problem a methodology is proposed that integrates aerial laser scanning data with high-resolution orto-rectified CIR images to extract reliable information of the terrain and of the objects on it (like buildings and trees). The methodology was tested in an urban area located in north Portugal. The obtained results show that in complex urban areas the proposed methodology has a superior performance than the conventional one.

The Brazilian Regulation NBR 9653 is a guide intended to evaluate mine and quarry blasting effects in urban areas. The first version, written in 1986 by the Committee of the Brazilian Associate of Technical Norms, is currently being revised. Cmrent regulations specify a maximmn PPV limit of 15 mmls (0.59 in/s) without consideration of frequency or type of structures being protected. The present regulation is still a draft and it is not validated. Several different agencies and institutions have participated in the Committee such as the Environrnental Agency from the State of São Paulo (CETESB), University of São Paulo (pOLI-USP), University of Rio Grande do Sul (UFRGS), ational Department of Mineral Resources (DNPM), Aggregate Industry (ANEPAC and SINDIPEDRAS), besides a number of industry representatives, explosives manufactures and independent consultants. The present regulation proposes to modify the lirnits of partiele velocity and introduces new definitions and criteria for evaluation of vibrations, as well recommendations to address blast vibration complaints.; 2005

No Brasil, a maioria das pesquisas com aves no ambiente urbano se restringe a parques urbanos, campi universitários e praças arborizadas. Com exceção dos estudos realizados em áreas verdes de Uberlândia, pouco se conhece sobre a avifauna nas cidades na região do Triângulo Mineiro/Alto Paranaíba. Os objetivos desta tese foram determinar a avifauna em cidades brasileiras por meio de dados secundários; comparar a distribuição dessas aves no ambiente urbano do país; determinar a riqueza e composição da avifauna em áreas urbanas na região do Triângulo Mineiro/Alto Paranaíba e comparar a avifauna encontrada no ambiente urbano com as aves de áreas naturais do Cerrado da região. Foi conduzida uma revisão bibliográfica e compilada uma lista de aves que foram registradas em áreas verdes urbanas no Brasil. A maioria dos trabalhos utilizados foi desenvolvida após 1995. Também foram realizados levantamentos em nove cidades da região do Triângulo Mineiro/Alto Paranaíba e em uma área natural da região. Além disso, foram utilizadas informações da ocorrência de espécies de aves na cidade de Uberlândia e em outras duas áreas naturais, por meio de dados secundários. As observações em todas as áreas foram realizadas de setembro de 2005 a janeiro de 2009...

As modificações ambientais de origem antrópica beneficiaram acidentalmente alguns animais que se adaptaram a áreas modificadas. Contudo, a biodiversidade de parasitos também foi afetada com o favorecimento de algumas espécies em detrimento de outras. No caso de carrapatos foram beneficiadas aquelas espécies que encontraram hospedeiros e ambientes propícios. No Brasil capivaras (Hydrochaeris hydrochaeris Linnaeus 1766) e os carrapatos Amblyomma cajennense Fabricius 1787 e Amblyomma dubitatum Neumann 1899, se expandiram em muitas áreas urbanas onde ameaçam o bem estar humano e de animais domésticos pelas lesões cutâneas infligidas e espoliação. Além disso, estão associados, em alguns locais, á transmissão da febre maculosa, doença de elevada letalidade ao homem. Este trabalho teve por objetivo analisar os fatores que determinam o estabelecimento e expansão de capivaras e carrapatos em áreas urbanas na cidade de Uberlândia. Em 2008 realizou-se mensalmente em quatro áreas urbanas e uma reserva ecológica a contagem direta de capivaras por transectos lineares calculando-se o índice de abundância e densidade. Coletou-se carrapatos do ambiente no verão de 2008 utilizando-se armadilhas de gelo seco e arraste de flanela nos mesmos transectos. Observou-se que populações de capivara em grupos com número de indivíduos superior ao encontrado em áreas naturais se estabeleciam em locais que...

This document builds upon several recent studies and reports carried out in the 2006-2007 period. The first note, entitled analysis of housing supply mechanisms (World Bank), analyzes the situation of housing supply in urban areas in Egypt, including the study of existing formal and informal mechanisms for the delivery of urban housing, the institutions responsible for supply and regulation, the characteristics of the formal and informal stock, and the institutional and regulatory framework governing land use planning and development. The second is a housing demand study in Greater Cairo (USAID TAPRII), which uses household data surveyed in December 2006 and yields results on the housing demand and household characteristics in the Greater Cairo Region. The third is an analysis of subsidized housing programs (USAID TAPRII), which assesses past, existing and pipeline subsidy programs in Egypt. International Best Practices were presented at a high-level workshop held in April 2007 with the intent of assessing different schemes of housing subsidies and reforms used in other emerging markets...

This newsletter concerns the relevance for social funds in Urban Areas. Social funds face a common challenge of sustaining the community capacities that are built and investments that are supported beyond the relatively short lifespan of external funding. For long-term sustainability, external funding needs to be replaced by a steady flow of domestic revenue. The Community foundation (CF) approach offers a number of advantages for urban work. Community foundations are independent organizations that provide grants to support a variety of projects identified and implemented by local residents. A CF does not replace the scale of resources and national reach achieved by social funds. But it can provide a partial answer to the sustainability challenge in some large and medium-size urban areas, where it can mobilize local resources and sustain social dynamism and participation in broad areas of development work.

Previous analyses of crash statistics have indicated that older drivers (aged 65 years and older) have fewer crashes than other age groups. However, they have an elevated crash risk on a per kilometre driven basis and are at an increased risk of death and serious injury from crashes. Rural older drivers may be particularly at risk due to a greater dependence on driving, which may create a reluctance to cease driving. It is often dem onstrated that motor vehicle crash fatality rates are higher in rural areas than urban areas. However, more research that compares the crash, serious injury, and fatality rates of rural and urban older drivers is required. A database of police-reported road crashes in South Australia, the Traffic Accident Reporting System, was used to obtain crash, serious injury, and fatality data for 2004 to 2008. The crash involvement of drivers of various age groups from both rural and urban areas was adjusted for population and licensure exposure measures. Crashes involving rural drivers aged 75 and over were more likely to have resulted in a serious or fat al injury than crashes involving their urban counterparts. The results indicate that rural older drivers present a unique road safety problem.; http://www.roadsafetyconference2010.com.au/program_new.html; Thompson...

This note is part of a series that examines the factors that facilitate the scaling up of Community Driven Development (CDD) programs. The note highlights the experience of CARE Zambia's Program of Support for Poverty Elimination and Community Transformation (PROSPECT) initiative, which applies a community based approach to reduce poverty in peri-urban areas of Lusaka, and discusses the importance of linking CDD with structures, and processes outside community boundaries, to ensure that they are able to scale up in more dynamic and sustainable ways than simple replication. It also examines the difficulties of doing so in the face of opposition by entrenched political interests.

The report is organized into three chapters: chapter two looks at the pace and patterns of India's urbanization, providing a 100-year perspective on demographic shifts and a 20-year perspective on the spatial distribution of jobs across India's portfolio of settlements. The review is based on a careful, spatially detailed analysis of data from economic and demographic censuses, annual surveys of industry, national sample surveys, and special surveys of freight transport. This chapter provides diagnostics on whether Indian industry is adequately exploiting agglomeration economies and whether there are hints of specific barriers to the natural tendency of standardized industry to reshuffle from large metropolitan areas to smaller urban areas. Chapter three examines specific policy issues and investment bottlenecks that are curbing the pace and benefits of urbanization in India. The policy issues relate to land markets and housing, connectivity (within and between cities), and access to basic services. The purpose of this analysis is to unravel the specific distortions that may be preventing India from reaping the entire range of benefits of urbanization. Chapter four provides some options for policy reform...

Evidence is mounting that secure property rights have positive effects for poor people in general and women in particular. The aim of this report is to review what is known about women s access to and control over land and real property in urban settings, identifying approaches to strengthening property rights that enhance women s agency, and sharing key lessons. Section two synthesizes the evidence on urban women s priorities with respect to land and housing; the factors that influence women s access to and control over land and secure tenure, including legal and institutional frameworks and social relationships, especially within the family; and what is known about the extent to which women have access to, control over and use of urban land and housing, and through what forms of tenure. In section three, recent reform of laws, policies and practices to meet the needs of poor people in urban areas, especially women, will be assessed. Section four provides a short discussion of some of the strategies, tactics and alliances that are being adopted to bring about legal reforms and to influence the content...

The Local Health Commission (LHC) was established in 1940. Its significance lies in the fact that it adopted a public health-based approach to local governance and that it delivered health and welfare services to residents of the neglected black and multi-racial urban areas. Even though its mandate was the antithesis of the goals of urban apartheid, the LHC expanded its scope after the National Party came into power in 1948. This dissertation is firstly, an institutional history of the LHC. Secondly, it examines the ways in which black urban residents practiced in municipal institutions by demanding that the LHC not only fulfill its mandate but, that it also amend its programs in order to meet their needs. A third and final theme of this dissertation is the role of Advisory Boards in addressing the public health crises specifically, ways in which the ABs held the LHC accountable. By exploring the LHC through these three themes, this dissertation addressed larger historical questions: firstly, the role of white liberal bureaucrats in the development of public health and urban governance in South Africa and secondly, the nature of black people’s participation in state institutions before 1994.; Thesis (Ph.D, History) -- Queen's University...

Research indicates that older drivers have an increased risk of being seriously or fatally injured if they crash. However, it is important that older drivers do not cease driving prematurely because driving enables them to remain mobile, which is important for their independence, health and well-being. Older drivers who live in rural or remote areas are of particular interest because the nature of their driving environments may further increase their risk on the road and restrict their mobility. In terms of risk, certain factors that are more common in rural driving environments, such as roads with high speed limits, may contribute to an increased likelihood that older rural drivers will be seriously or fatally injured if they crash, compared to older urban drivers. With respect to mobility, the longer distances that older rural drivers have to travel to reach their destinations, compared to older urban drivers, may restrict their ability to undertake everyday lifestyle activities, particularly those activities that are discretionary in nature (e.g. social activities). The aim of this thesis was to examine the safety and mobility of older drivers who live in rural areas of South Australia, compared to their urban counterparts. This was achieved through five independent studies. Studies 1 and 2 involved the analysis of crash...

Good agricultural soils are a scarce and exhaustible resource, essential for providing regular food production to societies and to the idea of sustainability. The protection of these soils is particularly important in Mediterranean landscapes, where there are strong natural and cultural contrasts and the fertility of land is based mostly on human activity. In Portugal, law protects soils since the early 1970s and in 1982 good agricultural soils were classified and safeguarded by law as National Agriculture Reserves (RAN) – non aedificandi – areas particularly suitable for agriculture. Even private land is considered of collective importance, protected by heavy restrictions in use and management. Nevertheless, once land is required for urban development, it is reclassified as urban soil and included in urban areas. The reflection on Common Goods from a Landscape Perspective, leads us to the idea of a functional conversion of agricultural soils in urban areas, sustained in the valorisation of these exceptional resources as productive functions in urban areas. This implies the maintenance of these soils as RAN in urban areas and the development of an evolutionary dynamic, reinforcing the idea of a common good – the return of the best soils to agriculture in urban areas – expressing the ecological...

La gran mayoría de la población europea habita en ciudades y el mejoramiento de la calidad de vida en zonas urbanas constituye un objectivo primordial de las políticas gubernamentales. Las ciudades se ven típicamente afectadas por apiñamientos, tráfico intenso, contaminación atmosférica y acústica, y factores que aumentan su vulnerabilidad con respecto a riesgos naturales. Esta Tesis explica cómo los ecosistemas contribuyen a mejorar la habitabilidad de las ciudades, con foco en zonas urbanas europeas medianas, sirviéndose para ello de estudios empíricos integrados (por ejemplo cualitativos y cuantitativos o socio-ecológicos), así como estudios relevantes con respecto a las medidas a tomar por las autoridades gubernamentales. Explora cómo y porqué las zonas urbanas pueden beneficiarse, en términos del bienestar de sus habitantes y de la reducción de las vulnerabilidad frente a riesgos naturales, de una más amplia gama de medidas y soluciones cuando se tienen en cuenta en forma apropriada los aspectos ecológicos utilizando diferentes escalas geográficas. La revisión de la literatura consultada para esta Tesis comprueba que las funciones reguladoras de los sistemas ecológicos a menudo proveen alternativas eficientes y rentables o soluciones complementarias para las infraestructuras que contribuyen a asegurar el bienestar de la población urbanas y reducir el riesgo de desastres. La investigación empírica en la ciudad de Colonia (Alemania) demuestra que las variables medioambientales juegan un rol central y decisivo...
