Recent studies have intended to quantify urban consumption and trade in Amazonian towns. However, little is still known about the different ways in which bushmeat is made available in urban areas, including commercial and noncommercial flows, and how those flows contribute to link forests to urban livelihoods. In this study we qualitatively describe the structure and functioning of bushmeat flows in terms of species, catchment area, stakeholders involved, and the motivations for their activity in the main towns of the Amazon trifrontier region between Brazil, Colombia, and Peru.  We show that bushmeat trade to urban areas exists under an organized but invisible commodity chain providing a source of income to about 195 persons. Bushmeat is made available...

Nature-based solutions promoting green and blue urban areas have significant potential to decrease the vulnerability and enhance the resilience of cities in light of climatic change. They can thereby help to mitigate climate change-induced impacts and serve as proactive adaptation options for municipalities. We explore the various contexts in which nature-based solutions are relevant for climate mitigation and adaptation in urban areas, identify indicators for assessing the effectiveness of nature-based solutions and related knowledge gaps. In addition, we explore existing barriers and potential opportunities for increasing the scale and effectiveness of nature-based solution implementation. The results were derived from an inter- and transdisciplinary...

The population ecology of Securidaca longepedunculata Fresen. in the Nylsvley Nature Reserve, Limpopo Province, South Africa
Provedor de dados: 85
Autores: Tshisikhawe,MP; Baloyi,O; Ligavha-Mbelengwa,MH; Bhat,RB.
Securidaca longepedunculata Fresen., commonly known as the violet tree, belongs to the family Polygalaceae. It is widely distributed in tropical Africa, Mozambique, as well as in the North- West and Limpopo provinces of South Africa. The Vhavenda people use the roots of this species as an aphrodisiac. The species is co-dominant in the savanna vegetation of the Nylsvley Nature Reserve. This research looked at the ecology of the study species within the Nylsvley Nature Reserve because of its importance there. Understanding the population structure and environmental factors that impact on the species might help in assessing the population in urban areas. The population of the study species in the reserve displayed an adequate growth curve, when looking at its...

Morbilidad autoreportada y los retornos a la salud para los varones urbanos en el Perú: enfermedad vs. incapacidad
Provedor de dados: 31
Autores: Murrugara,   Edmundo; Valdivia,   Martin.
El efecto del nivel de salud de los individuos sobre su productividad y sus ingresos es incuestionable desde varios puntos de vista. Sin embargo, la medición de ese efecto ha sido bastante más complicada que, por ejemplo, la correspondiente al efecto de la educación. Las razones de esta complejidad son de carácter conceptual, técnico y de calidad de la información. Esta medición se complica aún más en países en desarrollo debido a las limitaciones de los indicadores de salud disponibles, en su mayoría afectados por la propia percepción del individuo.  En este sentido, el presente reporte muestra evidencia acerca de los determinantes de salud para los varones adultos de zonas urbanas y sus efectos en la productividad, usando dos medidas de morbilidad...

DESIGUALDADE ENTRE RICOS E POBRES NO ACESSO À EDUCAÇÃO NO BRASIL RURAL E URBANO
Provedor de dados: 31
Autores: Ney,   Marlon Gomes; Carvalho,   Ailton Mota De; Souza,   Paulo Marcelo de.
Estudos destacam a existência de um forte efeito da desigualdade de oportunidade educacional na reprodução do elevado nível de desigualdade de renda no Brasil. Neste artigo, é analisada a desigualdade de oportunidade educacional no meio rural e urbano, utilizando um modelo de aquisição de educação que define graficamente a proporção de jovens em domicílios pobres, intermediários e ricos que completou cada nível de escolaridade. Os resultados revelam que as dificuldades para a democratização do acesso ao ensino são bem maiores no meio rural, onde a evasão escolar dos jovens pobres é muito mais rápida no ensino fundamental do que nas áreas urbanas.---------------------------------------------Several studies in Brazil show a strong effect of educational...

Aphididae (Hemiptera) on ornamental plants in Córdoba (Argentina)
Provedor de dados: 99
Autores: Szpeiner,Alfonsina.
In 30 surveys across Cordoba city and surroundings (Argentina) I recorded, from November 2001 to May 2002, a total of 109 ornamental plants infested with aphid colonies. Surveys were conducted in the local botanical garden as well as homestead gardens and nurseries. Seventeen species of aphids were identified, 4 of which are new species in the area, from 47 ornamental plants. In a total of 59 plant/aphid associations, 38 new associations were found. I present the first record of aphids colonizing Cactaceae in Argentina. Most aphid colonies were medium and a high proportion (more than 40%) showed alate individuals. The most frequent aphid species, Aphis gossypii Glover and Aphis craccivora Koch were especially associated with the most frequent damages:...
