The issue of water scarcity, besides being a relevant and contemporary environmental problem, can be characterized as a social phenomenon, the result of inadequate cultural practices. As such it can be studied by Behavior Analysis, more specifically, from the point of view of selection by consequences. In this context, our objective was to identify if campaigns and programs of water conservation are consonant with Behavior Analysis’ principles on how to change and control individual behavior in the cultural dimension. Overall, data indicate the absence of contingent reinforcement on behavior of water waste and conservation and the presence of mentalistic practices, in contrast with the foundations of Behavior Analysis, especially with regard to the logic of selection by consequences.

The Atlantic Forest biome, reduced to 12% of its original coverage, holds a significant portion of brazilian biodiversity, with high levels of endemism. Among the few remaining areas of the Atlantic, there is the region between the Complex of Cantareira and the municipality of Nazaré Paulista, which will be the object of study of this work. Using the concepts of Landscape Ecology, and analysis of thematic maps, this study aims to characterize the region in a ecologically scaled perspective, identifying two types of hotspots: i) for conservation and ii) for maintain habitat connectivity. Concepts of Landscape Ecology as landscape structure, patches, matrix, corridors (structural and functional) and connectivity, as well as their effects on local biodiversity was adopted and applied in the study region. We also analyzed the effects of roads, hydrographic system, Permanent Protection Areas (PPAs), and Conservation Units for flora and fauna maintenance at regional scale. This allowed us to define strategies and priority areas for the conservation and restoration of forest fragments of Atlantic Forest remnants within the study region. This study generated relevant knowledge for a better planning the region in order to create best conditions for the maintenance of regional biodiversity, and consequently, allowing to improve the quality of life for local population

In the present work we performed molecular cytogenetic studies in two different populations of Astyanax bockmanni from streams of Botucatu, SP: one from Capivara river, on Tietê river basin and one from Água da Madalena river, on Paranapanema river basin. The results showed that the population of Astyanax bockmanni from Capivara river have a diploid number of 50 chromosomes, with karyotype consisting of 8 methacentric, 14 submethacentric, 12 subtelocentric and 16 acrocentric, while the individuals of the population from Água da Madalena river have 50 diploid chromosomes but with karyotype organized in 8 metacentric, 14 submetacentric, 16 subtelocentric and 12 acrocentric. Also, the rDNA 18s sequences are widely dispersed throughout the genome of two populations, with intra and interindividual variations. On the other hand, the sequences for rDNA 5S and Histone H1 remained chromosomally conserved in these two samples and sites located in pairs 2 and 19 (rDNA 5S) and the pairs 2 and 15 (Histone H1). The low dispersion of structural genes and a functional dynamic independence between sequences of rDNA 5S and rDNA 18S may be related to the process of karyotype maintenance and differentiation in these populations of Astyanax bockmanni

Habitat loss and fragmentation of landscapes endanger the planet’s biodiversity. Strategies for identify priority areas for conservation and restoration of biodiversity rich areas becomes essential for the planning of the management of these landscape become successful. This study aims to propose a novel, transparent and replicable method for choosing priority areas for restoration, and includes the following steps: (a) identification of regional biodiversity hotspots for conservation; (b) identification of priority areas for restoration with the greatest potential to increase the connectivity of the fragments already existing; (c) estimate the potential richness of understory birds before and after restoration, analyzing the gain of species for the future scenario. In order to identify the corridors to be restored in a future scenario we considered the approach of multiple corridors, which aimed to connect the main fragments within the region through analysis of multi-paths. Already existing regression models were applied to estimate the richness of the landscape considering three models: a) species richness as a function of patch area of the fragment selected as hotspots; b) richness as a function of areas connected by structural corridors and c) connected area for species which are able to access nearby fragments within 20m. The gain of species for future scenario which consider the potential restoration of selected areas was estimated. Based on our results we observed that species that use corridors showed the highest increment of species richness of understory birds. As a result it had to restore corridors to model species with the ability to use forest corridors was the highest gain potential species richness of understory birds. The methods proposed method in this study appears provide new ways to ensures a better cost / benefit relationship for restoration projects by increasing the chances of better reach high levels of...

Living organisms are constantly subjected to the action of free radicals, which are one of the causes of oxidation reactions, because they have on free electron, what makes it very reactive. They are products of organism reactions or they are produced by exogenous factors, such as tobacco. Fatty acids are the most vulnerable target, and may suffer lipid peroxidation, what affects the cell structure. Cardiovascular diseases, cancer and diseases of aging are occurrence of these reactions in the organism related. The aliments are also subjected to suffer oxidation reactions, what make them unfit for consumption and decreasing the useful life. Synthetics antioxidants are used as aliments preservatives, but they present some toxicity for the organism. Studies for the utilization of natural antioxidants have gained more importance in recent decades, due to the conservation potential and low toxicity. Phenolics compounds are largely present at the vegetable kingdom and they present high antioxidant potential due to the neutralization and kidnapping of free radicals capacity. These compounds are used by the industry at the aliments conservation, specially the phenolics acids. The consumption of aliments rich in phenolic compounds, such as teas, wines and fruits are low incidence of degenerative diseases related. This study consists in a bibliographic revision that covers these compounds importance in diet and at the food conservation, and the methodologies and difficulties in the extraction process due to variety of molecules of this group.

Cerrado is the second biggest biome of Brazil. The broadest floristic diversity includes many species with medicinal properties. First, in this study was highlighted some important aspects that known Cerrado at Brazilian environmental sitting and main problems of impacts at the biome by the inside of our country. Second, a bibliographic search was presented to point uses and importance of plants at treatments, setting some examples of Cerrado’s species that has medicinal properties. Then, a reflection about the relation of use, popular knowledge and the local communities participation at the construction of conservationist and sustainable thoughts. Finally, a real example of conservation based on traditional knowledge in a riverain population.
