The invasion of five alien species in the Delta do Parnaiba Environmental Protection Area, Northeastern Brazil

Marine biological invasions have been regarded as one of the major causes of native biodiversity loss, with shipping and aquaculture being the leading contributors for the introductions of alien species in aquatic ecosystems. In the present study, five aquatic alien species (one mollusk, three crustaceans and one fish species) were detected during dives, shore searches and from the fisheries on the coast of the Delta do Parnaiba Environmental Protection Area, in the States of Piaui and Maranhao, Northeastern Brazil. The species were the bicolor purse-oyster Isognomon bicolor, the whiteleg shrimp Litopenaeus vannamei, the giant river prawn Macrobrachium rosenbergii, the Indo-Pacific swimming crab Charybdis hellerii and, the muzzled blenny Omobranchus punctatus. Ballast water (I. bicolor, C. hellerii, and O. punctatus) and aquaculture activities (L. vannamei and M. rosenbergii) in adjacent areas are the most likely vectors of introduction. All exotic species found have potential impact risks to the environment because they are able to compete against native species for resources (food and habitat). Isognomon bicolor share the same habitat and food items with the native bivalve species of mussels and barnacles. Litopenaeus vannamei share the same habitat and food items with the native penaeids such as the pinkspot shrimp Farfantepenaeus brasiliensis, the Southern brown shrimp Farfantepenaeus subtilis, and the Southern white shrimp Litopenaeus schmitti, and in the past few years L. vannamei was responsible for a viral epidemics in the cultivation tanks that could be transmitted to native penaeid shrimps. Charybdis hellerii is also able to cause impacts on the local fisheries as the species can decrease the populations of native portunid crabs which are commercialized in the studied region. Macrobrachium rosenbergii may be sharing natural resources with the Amazon River prawn Macrobrachium amazonicum. Omobranchus punctatus shares habit with the native redlip blenny Ophioblennius atlanticus and other fishes, such as the frillfin goby Bathigobius soporator. Some immediate remedial measures to prevent further introductions from ballast water and shrimp farm ponds should be: (i) to prevent the release of ballast water by ship/vessels in the region; (ii) to reroute all effluent waters from shrimp rearing facilities through an underground or above-ground dry well; (iii) to install adequate sand and gravel filter which will allow passage of water but not livestock; (iv) outdoor shrimp pounds located on floodable land should be diked, and; (v) to promote environmental awareness of those directly involved with ballast water (crews of ship/vessels) and shrimp farms in the region.

Análise da implantação das certificações ambientais LEED e AQUA: estudo de caso em alguns empreendimentos

Given the large potential impact that the construction industry has on the environment and the need to reduce environmental degradation , environmental certifications are important tools of environmental management. This work deals with the environmental certifications of sustainable buildings LEED and AQUA . This project employed the method of exploratory research to identify the requirements that impose the greatest difficulties in the implementation of LEED and AQUA , surveying the reasons for the choice of certification to be deployed and to analyzing the main benefits perceived by certified organizations. Concepts related to the topic were obtained from the literature, leading to the development of a questionnaire that was applied in organizations that have gone through the above certifications . From the analysis of questionnaires, it was possible to highlight that the main reasons for the adoption of an environmental certificate in the construction industry are linked to economic issues such as greater market recognition and appreciation of the project and what is still needed to invest in environmental awareness industry and the whole society

Proposta para a implantação de uma trilha interpretativa com bases na Pedagogia Waldorf na Floresta Estadual Edmundo Navarro de Andrade - Rio Claro, SP

At a time when people turn increasingly to technological innovations and virtual networks, a closer interaction with the environment can provide sensitizing experiences. One tool that facilitates this approach is the interpretative trail: its use in a Unit of Conservation (UC) allows more contact between the visitor and the nature elements. This research aimed to propose the establishment of an interpretative trail at the State Florest “Edmundo Navarro de Andrade” (FEENA) in Rio Claro (SP) with theoretical bases from Waldorf Pedagogy. The proposed trail is destined for students with 07-14 years-old, a period that the awareness is more accurate in a person, according to Waldorf tenets. On the path of the trail, we propose some educational activities at the points of interpretation: storytelling about environment; “photograph” the place with a drawing; create a song with sounds produced by the body and by nature elements; blindfold guide and a circle of people to share experiences. The activities aim to provide in the student a close and harmonious contact with oneself, with other people and with the natural world, and also serve as a support for programs of public use and environmental education at UC. The environmental awareness process in the context of FEENA - which has a significant landscape valuation - develops through the sensibilities of exterior and interior world. And also develops with the creation if images, thoughts, feelings and interdependencies relationships. Therefore, the ecologic education allows changes and formation of values and sensitive attitudes to students about the environment

Desidratação de lodo proveniente de ETA através de tubos geotexteis

Currently exists a growing concern for the preservation of the environment Around the world, the environmental awareness in Brazil has strengthened during the past two decades. This concern in Brazil arises from the creation of mechanisms of supervision and punishment on the part of the environmental agencies. In order to meet the pertinent legislation many public and private companies have performed dehydration of waste generated in the process of treatment of industrial effluents, waste water and water treatment in order to reduce transport and disposal costs. The use of geotextile tubes has proven technically and economically feasible to be applied in various situations from water treatment to mining tailings. This work presents the solution adopted for an environmental liability in water treatment plant through the use of geotextile tubes to reduce the water content of the disposal. We evaluated the size distribution curves, Atterberg limits, and chemical composition of the residue. Found high concentrations of aluminum in the waste which would characterize environmental pollution if disposed off directly in nature with no treatment

Diagnóstico dos riscos e impactos ambientais da suinocultura no Ribeirão dos Pinheirinhos, município de Torrinha, (SP)

The porcine activity is characterized by its great pollution capacity, generally produce loads of waste that usually are released in superficial water or soil without concern for the consequences to the environment. With this in mind, this study aimed to adjust the porcine production to the protection of water resources, in particular, Ribeirão dos Pinheirinhos in the town of Torrinha (SP), through inventory and diagnosis of the environmental impacts already present and environmental hazards linked to the activity in question. To achieve the proposed objectives, the productions of porcine on the studied area were raised and georeferenced, viewed and analyzed according to the technical and scientific literature. The production visited showed to be at odds with the protection of water resources due to lack of technical criteria in the development of treatment systems and waste handling, indiscriminate use of effluent and waste in the fertilization of crops and the lack of knowledge of producers on the influence of porcine waste into the environment. Based on these results, were set guidelines for action in the environmental awareness of farmers, to stimulate voluntary and conscious initiatives of environmental conservation in the direction of settlement of the activity.

A necessidade da formação da consciência ambiental na sociedade contemporânea: um estudo sobre as relações dialéticas entre o ser humano, a natureza e a cultura na obra de Ítalo Calvino

The present work has for objective to analyze the issue of training environmental awareness and its role in contemporary society. With the alarming scenario of degradation and environmental imbalance , political, social and non-governmental institutions have established the urgent need for an education that make changes in social behavior in relation to the environment. With this design is establishing environmental education, however the economic , financial and social scenario in which is inserted dismantles its effectiveness , since the transformations of modernity incited alienation, reification , individualization , indifference and consumerism . In this juncture it is noticed that environmental education needs to be analyzed by the perspective of a man in critical reflection of the capitalist structure. Given this need , it is proposed to reading Italo Calvino's work , since it approach the whole context of modern man , with his ailments , anxiety, exploitation , selfishness and destructive action of itself, others and the environment in living

How to progress from discourse to practice? a new agenda for change in medical schools into the next decade

In the context of medical school instruction, the segmented approach of a focus on specialties and excessive use of technology seem to hamper the development of the professional-patient relationship and an understanding of the ethics of this relationship. The real world presents complexities that require multiple approaches. Engagement in the community where health competence is developed allows extending the usefulness of what is learned. Health services are spaces where the relationship between theory and practice in health care are real and where the social role of the university can be revealed. Yet some competencies are still lacking and may require an explicit agenda to enact. Ten topics are presented for focus here: environmental awareness, involvement of students in medical school, social networks, interprofessional learning, new technologies for the management of care, virtual reality, working with errors, training in management for results, concept of leadership, and internationalization of schools. Potential barriers to this agenda are an underinvestment in ambulatory care infrastructure and community-based health care facilities, as well as in information technology offered at these facilities; an inflexible departmental culture; and an environment centered on a discipline-based medical curriculum.
