“…In addition, there were seven studies that took place in various countries or that were not linked to a particular geographical area. The prevalence of studies in Brazil and Mexico may be due to the combination of three different issues: the great extension of these two countries, their high biodiversity (Brazil and Mexico are megadiverse countries), and their economic growth (Sarukhan 2012;Scarano et al 2012). In particular, Brazil invests intensively in science and has a high scientific production at the international level (Regalado 2010;Scarano 2007).…”

Literature review of the use of birds as pets in Latin-America, with a detailed perspective on Mexico

et al. 2014

A large amount of birds are harvested from the natural environment for the pet market. This trade is a conservation issue and an economic income for many people, two aspects not analyzed yet as a complex system of causes and effects. Though bird trade is common in Latin-America there are few published studies. Therefore, we reviewed available literature to understand the background of this topic and to identify future relevant research topics. We collected, summarized and discussed literature about bird use as pets in Latin-America, with a detailed approach in México. We searched by keywords in search engines. We got a database of 128 documents. Brazil was identified as one of the main countries of bird use research. Most of the papers focused on parrots (27%) and were conducted at a local geographical level (47%). Half of the papers are focused on the general use of birds, 44% on the use as pets and 5% on other uses. The most common techniques employed for gaining information belong to the social sciences. In Mexico, 82% of the information is “gray literature”, mainly congress abstracts. This literature review shows that wildlife use in general and wild birds use as pets in particular are common in Latin-America. We bring to light that most information is not found in peer review journals and contains only useful bird lists. Finally, we found that social organization and actor’s perception research is scarce so we suggest more research in this direction in order to implement better management policies

“…Recently, in RIO + 20, once again this aspect was addressed, now emphasizing the idea of "green economy" (Scarano et al, 2012). In fact, many farmers do not take advantage of the area's full potential (Silva et al, 2006;Brannstrom et Valipour, 2012Valipour, , 2013Sá et al, 2013).…”

Optimization of land use can be attained by incorporating technologies to crop production, such as the use of diazotrophic bacteria, fertilizers, and pesticides. Seed inoculation with Azospirillum is an alternative that favors the incorporation of green agriculture in regions of conventional farming, such as the Brazilian savannah (Cerrado). However, limited information is available about this bacterium's contribution to agriculture when other technologies are also incorporated. This study evaluated the performance of maize hybrids inoculated, or not, with Azospirillum brasilense, with or without fungicide applications, and subjected to different nitrogen rates under Cerrado field conditions. Each factor analyzed contributes to the increased maize grain yield. The use of inoculants containing plant growth promoting bacteria is a good option to ensure high yield of maize. Still, nitrogen should not be replaced, neither totally nor partially, by seed inoculation with Azospirillum. Fungicide applications should be done, as required, during maize cycle. Moreover, specific maize breeding programs should consider the affinity between Azospirillum strains and maize hybrids, mainly for regions with nitrogen deficient soils, like Cerrado. Thus, by incorporating additional technologies, maize crop farmers can optimize land use and, consequently, reduce the expansion into new agricultural areas.

“…Uso de séries temporais NDVI do MODIS para mapeamento da cobertura vegetal natural e exótica em uma região de transição Cerrado-Caatinga, 70 p., (UnB-IH-GEA, Mestre, Gestão Ambiental e Territorial, 2015 2 (FERREIRA et al, 2008LIMA et al, 2012). Em períodos mais recentes, as políticas públicas e as obrigações que vem sendo assumidas pelo governo brasileiro perante a comunidade internacional levam a crer que o conhecimento e a preservação da vegetação nativa brasileira passam a ter ainda mais relevância (SCARANO et al, 2012a). Um fato que retratou isso foi a reafirmação, durante a realização da Conferência das Nações Unidas sobre o Desenvolvimento Sustentável na cidade do Rio de Janeiro, em 2012 (MINAYO, 2012), do compromisso de cumprir as ações prioritárias da Agenda 21, dentre elas a preservação dos recursos naturais, a redução das emissões de gases do efeito estufa e a redução dos desmatamentos (BARBIER, 2012;SCARANO et al, 2012b).…”
