The content of this article addresses two complex issues that concern contemporary society: Science of Human Functioning and Environmental Sustainability. On the one hand, the Science of Human Functioning, meeting the principles of the International Classification of Functioning (ICF) and Universal Design, aim the development of accessible projects, products and environments, used by everyone, at the greatest extent possible, free from adaptation or plans to remove architectural barriers. The Universal Design is a process for creating products that are accessible to everyone, regardless their personal characteristics, age, skills and needs. On the other hand, Environmental Sustainability, with principles already imbricated in the Science of Human Functioning, traverses towards the acquisition of realistic measures for the segments of human activities. Based on the emphasis of the sustainable development, it aims to meet current needs not compromising the possibility of future generations to meet their own needs. Thus, it seeks the balance in coexistence between men and the environment by taking care of environmental, social and economic aspects and seeking for alternatives to support life on Earth with no harm to the quality of the planet in the future. It is argued that the combination of the issues contains relevant potential for interdisciplinary action, bringing together professionals from several fields of knowledge that, by socializing their experiences aiming at improving the human functioning and quality of life of people and environment, will be able to innovate and reinvent the knowledge for benefiting welfare, thus contributing effectively to society.

The belief in the existence of an ecological crisis that would affect the future of the planet, is one of the factors that causes the appearance of ecological concern, resulting in the adoption of non-predatory consumer practices and more respectful relationships with non-humans beings. This study starts from the assumption of the existence of an environmental question, and aims to investigate some of the cultural causes of human predation and identify possible ways in which environmental question can be treated critically to search overcomes. Follows the reasoning that western society as a complex of social relations, the capitalism, as a mode of production utilities and rational right, are all consequences of the modern rationality, cognitive and moral logic that transforms people and nature in satisfaction instruments of individual interests. However, despite being identified as the causative root of environmental question, modern rationality takes with it enough to promote the development of ecological respect, necessary in confronting and overcoming the environmental question, as it will be applied as a principle in redefinition of the relationship of human beings with themselves and with nature. And modern rationality can also make capitalism more efficient in the use and reuse of materials so as to consume fewer resources on the planet to satisfy human needs.

The ecology and sustainability have never been in question as they are today, this is because the planet has reached a situation in which problems related to consumption and waste production can not be ignored. Cities have become unhealthy and quality of life of urban man is increasingly impaired. As a form of escapism from the major centers, a significant number of people are looking for isolated communities and ecological order that there, in those isolated places, they are able to rescue the idea of community. The journalistic product The Village of the Mountain shows the daily life in an ecovillage and describes the challenges and ideologies of these people trying to build a more suitable place to live

The relationship between humans and the world around is getting less symbiotic and harmonic, so as with the other animals we share the planet with, mostly about domination of plagues, domination for food, company, work or fun. This last both are responsible for the beginning of the Circus as we know, with the exhibition of wild animals and horses, and have been increased with clowns, acrobats, and jugglers, street artists, getting to be one unified show all around the world, which most of them don´t have animals. Following this tendency, the PL 7291/06 is on process on the plenary assembly to forbidden the animals inside Circus. In that matter, this work is a Phenomenological perspective of the phenomenon Circus’s animals sited beyond the animal rights activists perspective. The Ideographic and Nomotetic analysis of the activist’s speech realize that is no discordance between then. All the speeches agrees that the animal must be out of the circus, and most of them agrees about the cruelty involving the animal´s domination, about that ONGs should be the better destination for this animals, and they shows lack of knowledge about the Brazilian Circus, with or without animals, their traditions and characteristics, so as the lack of knowledge about de ecology and biology of the animals involved.

The family Chironomidae is one of the most important groups within the macroinvertebrate communities, both in density and in richness, and because of its high adaptive value, has a wide distribution on the planet. These and other more specific features of each genus allow the use of this group of biomonitoring studies in the aquatic ecosystem, however, primarily, it is necessary to inventory the aquatic fauna. Thus, this study aimed to evaluate the taxonomic composition of Chironomidae associated with Eichhornia azurea in six lateral lagoons of Paranapanema River, where only five of them have very little information about the aquatic fauna associated with floating macrophytes. Furthermore, we analyzed the influence of environmental conditions on the richness and density of this community. Samples (biotic and abiotic) were held in March and August 2009 on the Ivo, Carmo, Sete Ilhas, Barbosa, Poço da Pedra and Coqueiral lagoons, which are upstream of the Jurumirim Reservoir. Samples with an area of 0.1976 m2 were collected at three banks of E. azurea of each lagoon. Then, they were washed in formaldehyde and water and fixed in 70% alcohol. The identification of morphospecies recorded 38 taxa (32 in March and 37 in August), where the Ivo lagoon is the richest (27 taxa). The density of each group varied according to each pond and is generally Asheum sp., Chironomus sp., Beardius sp., Parachironomus sp., Labrundinia sp., Tanytarsus sp., Ablabesmyia sp. and Polypedilum sp. the most representative. Limnophyes sp., Denopelopia sp., Paratanytarsus sp. and Parametriocnemus sp. were genders in lower density. The Dominance index ranged between 0.1490 (Barbosa Lagoon in March) and 0.4114 (Poço da Pedra Lagoon in March), and the Diversity Index ranged from 2.08 (Coqueiral Lagoon in March) and 3.58 (Barbosa Lagoon in August). The concentration of dissolved oxygen and pH were the environmental variables most correlated with the groups ...

The Brazil´s Atlantic coastal forest biome is considered one of the richest and most exuberant biodiversity of the whole planet. Still, other data shows the reality of this Brazilian forest: more than 93% of its original formation has been already devastated, being the human actions the greatest threat to the perpetuation of the balance and diversity of this ecosystem. This destruction affects all the fauna and flora, with even greater impact on medium and large mammals, due to its high demand on the availability of resources, living area and sensitivity to disturbances. However, today it is known the vital importance of these mammals in the preservation and maintenance of biological systems. Thus, the purpose of this study was to survey the species richness of medium and large mammals in a remnant neotropical forest located in Itatinga, SP,Brazil, using the indirect method of recording (traces on sand-plots, marking territorial, faeces, carcasses, scratches on tree trunks and vocalizations) and camera trapping. Data were collected during ten (10) consecutive months in the year 2008, from February to November. Within twenty-five plots of sand installed and monitored during the ten months were found fifteen (15) species of terrestrial mammals of medium and large, five (5) orders and twelve (12) families. Among them, we highlight the presence of threated species like the puma (Puma concolor), the deer (Mazama gouazoubira) and the giant anteaters (Myrmecophaga tridactyla). The chosen method showed up effective in raising terrestrial mammalian species of medium and large neotropical forest area, having a good applicability and advantages over other existing methods. The study area presents a huge diversity of species and, therefore, this work it is recommended to be only the beginning of new researches in the area in order to enrich...

Brazil has about 12 % of a life´s essential resource: the superficial fresh water of the planet. However, today it is possible to observe the bad management of this resource, generating serious consequences on the quality that results in the loss of the use´s availability. In this scenario, the catchment of rainwater for undrinkable use is an alternative that has been broadly studied for the scientific community. When planning a system of rainwater catchment, the sizing of the required volume of the tank that will keep the water has a fundamental importance for the project, seeing that the supersizing of the tank can bring high costs and the undersizing can bring shortage in the water supply. This paper used a methodology based on two concepts: the harvesting efficiencies and the attending efficiencies of the system. This method takes as principle that exist a perfect demand that minimize the repayment time, condition that happened when the efficiencies are equal. Brazilian’s cities with different weathers and different rainfalls where chosen to simulate the attending for different demands for a typical residence. The data where parameterized according to the roof area and the number of residents, that way is possible that a future conference can be easily done and it also ensure results closer to the reality. The results showed that cities with a lower period of drought, even those with high level of rainfall on the raining mouths, have lower potential of water supply. The cities where the rainfall is more constant and also more high, even small roofs areas and small tank´s volumes – about half of the size compare to the cities with less propitious conditions – can generate high levels of water saving. With an eye to promote the environmental sustainability, the investment on projects for the catchment of rainwater is a good alternative

The interspecific competition tends to favor the selection of divergent phenotypes minimizing the effect of this interaction. This process is termed character displacement and it is considered one of the main mechanisms promoting adaptive diversification. Brazil has the greatest diversity of amphibians on the planet and despite this great diversity; the role of character displacement in the process of Brazilian amphibian fauna diversification has not been studied. In the present study we tested the hypothesis of character displacement in four congeneric species pairs of frogs from the family Hylidae, occurring in the Atlantic Forest and Cerrado. We find evidence of character displacement for two pairs and parallel evolution for the remaining. Interestingly, the trend of character displacement was in species whose range covers less stable habitats. Since this is a pioneering study with neotropical hylid, we discussed issues considered relevant to elucidate mechanisms related to the maintenance of diversity

The issue of waste, historically, has been getting worse as a result of the world´s population increase and in order to meet their needs the consumption of natural resources and the generation has been constantly increasing, especially in large urban centers. The people involved in the collection of recyclable solid waste, called from now on as collectors, are responsible for about 90% of the waste sent to recycling industry in Brazil. Apart from having a role in the economy, the collectors have specific knowledge and skills necessary to identify, collect, sort and sell these wastes. This study aims to examine the possibilities and limits of COOPERVIVA – Cooperativa de Trabalho dos Catadores de Material Reaproveitável de Rio Claro - as an instrument of the municipal solid waste management system, and its experience as a recyclable waste collectors cooperative. The methodological procedures of this study rely on the literature research on the experiences of cooperative and the management of municipal solid waste. In addition to this review of the literature, fortnightly visits to the cooperative were held in order to experience their daily activities, and testimonies of the cooperative members were collected as well as documents and reports produced by COOPERVIVA. The results of this analysis are considerations of the limitations of the cooperative and recommendations aimed at maximizing their potential as a tool of the domestic solid waste management system of and as a recyclable waste collectors cooperative. Among other things it can be concluded that the urban selective collection of waste challenges the community to the reinvention of life and the relationships each individual with the planet.

The development of human societies and their activities generate many impacts on the environment and natural resources. The consequence of these problems is a disturbance of the systemic dynamics of Planet Earth. Study these impacts are a way to understand the workings of this system and undertake efforts to prevent minimize and anticipate scenarios caused by environmental impacts. In this sense, from a systemic approach seeks to understand the way how is the interaction of the components of the ecosystems, adopting for this task the hydrographic basin as a natural unit of planning and management in view of the fact all landscape elements (atmosphere, hydrosphere, biosphere and geosphere) interact so that the reflections of human activities can be represented in this unit. Thus, this study aims to quantify chemical erosion rates in the hydrographic basin of Ribeirao Monjolo Grande, Ipeúna (SP), which is relevant to analyze the geomorphological characteristics of the area, which may serve to better exploitation of natural resources

The dairy sector has undergone considerable economic losses due to low fertility rates due to adverse effects of heat stress on reproduction of cows. Genetic selection for increased production, coupled with the expanding dairy to tropical areas of the planet, and global warming has further aggravated the problem of heat stress. The effects of heat stress are multifactorial and act directly or indirectly at various levels of reproductive tissues, resulting in low fertility of cows, which in practice, results in reduced reproductive efficiency in the property, reducing the producers’ profit. Some strategies related to breeding biotechnology such as fixed-time artificial insemination, embryo transfer and use of BST, can minimize these effects and improve the reproductive efficiency of the herd
