For ecotourism to bring the expected benefits it is necessary that its assumptions are followed, including environmental education. The advance of the activity, however, has not been accompanied by the development of educational practice, showing up more studies that analyze local situations of environmental education in ecotourism. Thus, this study was conducted... tde@sc.usp.br (Bacchi, Renato) Mémoires de Maîtrise Mon, 22 Apr 2013 00:00:00 -0300 http://www.teses.usp.br/teses/disponiveis/91/91131/tde-08042013-104056/?&lang=fr http://www.teses.usp.br/teses/disponiveis/91/91131/tde-08042013-104056/?&lang=fr Dioscorea is the largest genus of Dioscoreaceae family and has a wide variety of species of economic interesting, for their edible and medicinal properties. This study aimed to characterize, by microsatellite markers, the genetic diversity of 42 local varieties obtained from the ex situ germplasm collection belonging do ESALQ/USP, originating from São Paulo, Minas Gerais, Pernambuco, Piauí, Mato Grosso and Goiás.

One of the subjects widely covered by the media is the environment. In Brazil, television is the reference for ordinary citizens to obtain information about environmental issues. The "Globo Reporter" is in the air for many years on Brazilian television. It can be considered as one of main means to popularize discourses on environment.

The production had various purposes and is still rising; therefore, currently eucalyptus plantation occupies more than four million hectares in Brazil. Its progress, however, highlights some concerns about the effects of cultivation on the native fauna because eucalyptus plantation is a monoculture although it has forestry profile.... tde@sc.usp.br (Calaboni, Adriane) Mémoires de Maîtrise Mon, 08 Apr 2013 00:00:00 -0300 http://www.teses.usp.br/teses/disponiveis/91/91131/tde-28032013-094611/?&lang=fr http://www.teses.usp.br/teses/disponiveis/91/91131/tde-28032013-094611/?&lang=fr The land use conversion is a major threat to wildlife because the landscape becomes fragmented and the areas occupied by native vegetation are reduced, altering the structure of animal communities. In this study, the medium to large-sized mammal community (> 1 kg) was evaluated in a fragmented landscape in eucalyptus matrix, in the southern São Paulo State, Buri and Capão Bonito municipalities (23°52'47" S, 48°23'24" W), using three different methods installed together (sand plots, camera-trap... tde@sc.usp.br (Lima, Elson Fernandes de) Mémoires de Maîtrise Fri, 05 Apr 2013 00:00:00 -0300 http://www.teses.usp.br/teses/disponiveis/91/91131/tde-28032013-095321/?&lang=fr http://www.teses.usp.br/teses/disponiveis/91/91131/tde-28032013-095321/?&lang=fr The expansion of market economy has changed the motivations in production and consumption among large and small farmers alike. One result of these changes is the disconnection between small farmers' livelihoods and the performing of agricultural activities. To small farmer populations, it has representing a diminishing importance of agricultural income and an increasing importance of other activities, such as part-time jobs, off-farm employment, and social benefits.

In the country the main problems faced by the planters are related to phytopathologies and phytophagous attacks that reduce productivity and can affect the prices of the product in the market. In this scenario, the control of phytophagous is necessary to avoid economic and productivity losses. Thus, spiders populations emerge as a potential control agent, due to the trophic strategy, completely dependent upon predation,... tde@sc.usp.br (Santi Júnior, Adelino de) Mémoires de Maîtrise Wed, 27 Mar 2013 00:00:00 -0300 http://www.teses.usp.br/teses/disponiveis/91/91131/tde-05032013-110229/?&lang=fr http://www.teses.usp.br/teses/disponiveis/91/91131/tde-05032013-110229/?&lang=fr With the global increasing concern around the environmental issue, the society starts to demand environmental responsible practices to the different sectors.
