13. Padrões bioenergéticos das aranhas de teia: considerações sobre a unidade e a diversidade do fenômeno / Patterns of bioenergetic of web spiders: considerations about the unity and diversity of the phenomenon
The physiological mechanisms are often applied to explain important evolutionary adaptations (e.g. endothermy) and ecology (e.g. physiological limitations to occupy a particular microhabitat) of vertebrates. Despite the fact that it improves vertebrates ecological and evolutionary hypotheses with possible processes and mechanisms, it is scarcely used to unde

14. COMPORTAMENTO DE TALUDE DA MARGEM DO RIO SÃO FRANCISCO SUBMETIDO À TECNICA DE BIOENGENHARIA DE SOLOS. / BEHAVIOR OF THE SLOPE OF THE SÃO FRANCISCO RIVER SUBJECTED TO THE SOIL BIOENGINEERING TECHNIQUE.
The lower San Francisco river had changed their hidrossedimentological behavior by changes in river channel through the impoundment of water reservoirs for the implementation of large hydropower projects. These direct impact on the stability of river banks, demands actions to mitigate the erosion resulting from soil mass movements. Soil bioengineering, which

15. Optimization of end milling parameters under minimum quantity lubrication using principal component analysis and grey relational analysis
Machining is the major reliable practice in accomplishment of metal cutting industries. The accelerated growing competition demands top superior and large quantity with low cost products. Metal working fluids have significant fragment of manufacturing cost and causes ecological impacts and health problems. This work attempts to advance a competent machining

16. Estructura de la comunidad de macroinvertebrados del arroyo Achiras (Córdoba, Argentina): análisis previo a la construcción de una presa
Regulation of rivers and streams modifies parameters that directly influence on the biota. In Achiras-del Gato endorheic basin has completed the construction of a midsize dam that will alter the limnological characteristics of the system and the structure of benthic communities. This study provides the first taxonomic records of macrobenthos of this lotic sy

17. As Novas ruralidades e as recentes alternativas da agricultura familiar no município de Itapiranga (SC)
The new rurality is creating job opportunities and income in family farming in the municipality of Itapiranga/SC, which must be analyzed. Have been numerous initiatives in this direction, such as recreation sites, agro-ecological gardening, farming, forestry, fish and small agro-industries derived from cane sugar (molasses, brown sugar and "Schmier"), rural

18. Modelagem ecohidrológica usando o PHABSIM como suporte para a gestão de recursos hídricos, com foco na outorga de uso de água / Hydrological Modeling Using the PHABSIM as a Decision Support for Water Management And Water Right as a Focus
Apesar de a água cobrir quase dois terços da superfície do planeta, a escassez de recursos hídricos tem sido apontada como um dos mais preocupantes problemas atuais e futuros. Neste contexto surgiu a ecohidrologia, que pode ser considerada uma nova área interdisciplinar que associa os processos hidrológicos e ecológicos envolvidos com o ciclo da água

19. Mapeamento geomorfológico aplicado na análise de impactos ambientais urbanos: contribuições ao (re)conhecimento de morfologias, morfocronogêneses e morfodinâmicas do relevo da bacia hidrográfica do Arroio Feijó - RS / Geomorphologic mapping applied to the analysis of urban environmental impacts: contributions to the (re) cognition of morphology, morphochronogenesis, and morphodynamics of the Feijó/ RS stream basin relief
Urban environmental impacts generate various social disorders. In many cases, the analysis of environmental impacts should be the agenda for everyday discussion, included in urban planning policies. As support to these policies of urban planning in a perspective of applicability of geomorphologic knowledge we highlight the thematic mappings in geomorphology.

20. Diversidade, diferenciação e biogeografia de pequenos mamíferos não-voadores na Mata Atlântica ao norte do rio São Francisco Centro de Endemismo Pernambuco / Diversity, differentiation and biogeography of non-volant small mammals of the Atlantic Forest north of São Francisco river - Pernambuco Endemism Center
The Brazilian tropical rainforests (Amazon and Atlantic Forest) present high species diversity and are currently separated by a belt of open and dry vegetation. Part of this belt is occupied by the Caatinga, where are found the Brejos de Altitude, evidence of the historical connections between the Atlantic Forest and the Amazon. The Pernambuco Endemism Cente

21. CitogenÃtica em peixes de cabeceiras de dois riachos pertencentes à bacia do Alto rio ParanÃ, regiÃo de Toledo (PR) / Cytogenetic in fishes from two headwaters streams belonging to the Upper Paranà river basin, Toledo (PR)
Cytogenetics studies were carried out in two genera of fishes from Pindorama and Lopei streams, Upper Paranà River basin, with cytossistematic and ecologic-evolutionary approaches. In Heptapterus mustelinus, the first cytogenetics characterization in the genus was carried out, verifying 54 chromosomes (26m+18sm+4st+6a), which is a diploid number not observe

22. Uma nova vida na mesma vida : um estudo de caso de reinserção familiar / A new life in the same life: a case study of family reintegration
The family environment is widely seen as the main context for the development of children. However, for various reasons, some families may put the welfare of their children into risk. According to the ECA-Children and Adolescents Laws (Brazil, 1990) it is necessary to apply protective measures in the case of threats or violation of children and adolescents r

24. O papel ecológico da neblina e a absorção foliar de água em três espécies lenhosas de Matas Nebulares, SP - Brasil / The ecological role of fog and foliar water uptake in three woody species from Southeastern Brazilian Cloud Forest
Fog deposition is an important water source in several terrestrial ecosystems. Fog water intercepted by the plants can run off to the soil or be absorbed by the leaves. However, very little is known about the ecological role of fog and the mechanisms and structures involved in foliar water uptake by woody species in tropical environments. In this context, we
