Description
An account of the resource
La urbanización global de los territorios, que es un fenómeno ecológico humano importante en curso, y cuyos impactos ambientales poseen niveles local, regional y mundial, presenta la característica notable de un crecimiento pronunciado de las ciudades pequeñas e intermedias, en las cuales la capacidad de planificación y gestión es usualmente ínfima, en comparación a las ciudades grandes. Es lo que se verifica en Brasil, donde las ciudades de tamaño medio, es decir, las que tienen poblaciones entre 100.000 y 500.000 habitantes están creciendo más rápidamente que las grandes ciudades, desde mediados de la década de 1990. El artículo tiene como objetivo trazar una tipología de las ciudades medias brasileñas por medio de análisis estadísticos multivariados. La tipología resultante señala dos tipos de ciudades, con demandas sociales, ambientales y de gestión diferentes. Algunas de estas ciudades se encuentran en hotspots de biodiversidad. En paralelo, hemos recopilado estadísticas sobre la gestión ambiental en marcha en estas ciudades. Nuestros resultados demuestran una baja efectividad de las acciones de gestión ambiental en estos municipios.

Description
An account of the resource
El presente artículo nos presenta el panorama del agro sinaloense desde finales del siglo XIX hasta los años treinta, en que el gobierno federal realizó el reparto agrario. Los extranjeros tenían el control económico tanto sobre las tierras, como sobre la producción de cultivos, los ingenios azucareros, las concesiones sobre las redes ferroviarias, etc. En reacción contra la política porfirista de dar facilidades a la inversión extranjera en el país, en particular a la agricultura, los gobiernos pos-revolucionarios se vieron en la necesidad de limitar la influencia y el poder de los extranjeros, especialmente de los norteamericanos en la economía nacional. Después del reparto cardenista se prosiguió al reparto agrario con la apertura de los distritos de riego y la aplicación de la Ley Federal de Aguas. A lo largo de estos años, las compañías norteamericanas salieron poco a poco del sector de la producción agrícola. Sin embargo, al cabo del tiempo, a partir de los sesenta las agroindustrias internacionales volvieron a penetrar con tal fuerza que ahora en gran medida la agricultura mexicana está dominada por el capital agroindustrial extranjero, esencialmente norteamericano.

El artículo analiza el déficit histórico en materia de políticas de gestión hídrica en Buenos Aires buscando identificar el modo en que este último condiciona las estrategias de adaptación al cambio climático. Se trata de un asunto alta complejidad en una metrópolis que se ha desarrollado en presencia de fuertes desigualdades sociales y ambientales. Se adopta un enfoque centrado en la perspectiva de la justicia ambiental, buscando mostrar cambios institucionales recientes a partir de la intervención de la Corte Suprema de Justicia de la Nación en una causa judicial donde los ciudadanos han exigido la recuperación ambiental de la cuenca Matanza-Riachuelo ejerciendo el derecho constitucional al ambiente sano.Consideramos el valor heurístico que tiene este conflicto para identificar los desafíos que enfrenta la gestión ambiental metropolitana y hacer un balance de las oportunidades y barreras en materia de políticas de adaptación al cambio climático en el mediano plazo.

Description
An account of the resource
Contexto: El presente trabajo tiene como objetivo diseñar y construir un sistema capaz de realizar el control de nivel de líquidos que se encuentren almacenados en grandes depósitos, también está orientado a su utilización en prácticas de control automático y a la transmisión de la información a distancia. Una energía renovable, sostenible y amigable con el medio ambiente, usada como alternativa para mitigar el cambio climático causado por uso de energías provenientes de los combustibles fósiles; pensando en ello, es muy importante estudiar el comportamiento de los módulos fotovoltaicos en condiciones realesnde funcionamiento. Método: Consta de diferentes etapas que satisfacen el cumplimiento del objetivo propuesto, está compuesto por alarmas sonora y lumínica en caso de derrames en los depósitos o por falta de comunicación entre sus componentes. La realización del control digital dentro del sistema requirió de un procedimiento de adquisición de datos implementado por Arduino con módulos XBee para la comunicación, además de una computadora personal. Resultados: Este tipo de procedimiento para implementar el control se escogió debido a la facilidad de ejecución, los beneficios y los bajos costos del sistema respecto a los existentes en el mercado; otra de las tareas realizadas fue el estudio práctico de las diferentes técnicas de control aplicadas a un sistema real para el monitoreo de nivel de líquidos en depósitos de gran capacidad. Conclusiones: La validación del sistema de medición fue realizada a través de una comparación entre los valores reales obtenidos con los instrumentos de medición y los valores mostrados por el sistema a través de la aplicación web que fue diseñada; el correcto funcionamiento de dicho sistema permitió su posterior instalación en depósitos reales.

En las últimas décadas, al hacerse más evidentes los efectos del calentamiento global, es indiscutible no pensar en el empleo de energías renovables y alternativas, de esta manera la idea de vivir en un mundo más limpio motiva cada día a más países y con ello a sus empresas y gobiernos a la búsqueda de medios que se sustenten solo de energías renovables. Este documento, procura analizar, el impacto que tiene el diseño industrial como un factor indispensable en el uso de energías renovables, mediante proyectos innovadores que parten de la idea de reducir el impacto ambiental, disminuyendo el consumo de energías no renovables que incrementan este factor. Se evalúa la evolución del uso de energías renovables en países sudamericanos, y su desempeño mediante la aplicación de esta poderosa herramienta. Finalmente se concluye haciendo hincapié en la importancia de crear productos o servicios para incrementar el uso de energías renovables a través del Diseño Industrial.

O Centro de Pesquisas da Mata do Paraíso (CPMP) é parte integrante do maior fragmento de Floresta Semidecidual Altimontana das imediações do município de Viçosa, sudeste de Minas Gerais. Como centro de pesquisas da Universidade Federal de Viçosa, ele tem servido para a coleta de dados de monografias de graduação, dissertações, teses e pesquisas de professores, principalmente dos Departamentos de Biologia Animal, Biologia Vegetal e Engenharia Florestal. Essas pesquisas têm sido conduzidas em trilhas preexistentes, aleatoriamente distribuídas pela mata, ou em novas trilhas abertas conforme a conveniência dos pesquisadores ou a exigência de suas pesquisas. Essa prática impede ou dificulta o mapeamento adequado de locais de amostragem e os monitoramentos temporal e espacial de comunidades animais e vegetais, bem como a repetibilidade de experimentos. No presente trabalho, descreve-se a implantação de um sistema de trilhas em 40 ha do CPMP, formado por um conjunto de cinco trilhas paralelas de 1.000 m e 11 de 400 m, formando 40 quadrados contíguos de 1 ha. O CPMP passou a ser uma das poucas reservas florestais no país a contar com um sistema ordenado e medido de trilhas, abrindo um novo leque de oportunidades para a realização de pesquisas de importância internacional. Destacam-se a urgência de manutenção das trilhas, a necessidade de seu georreferenciamento e a expansão da grade para 100 ha, a fim de que alcance padrões internacionais entre estações de pesquisa de comunidades florestais na região neotropical.Mata do Paraíso Research Center (CPMP) is the core area of the largest Lower Montane Semideciduous Atlantic Forest fragment in Viçosa region, southeastern State of Minas Gerais, Brazil. As a research center belonging to the Universidade Federal de Viçosa (UFV), it has been an important site for the fieldwork of undergraduate monographs, Master and Doctorate Thesis, and research conducted by professors, mostly from the Animal Biology, Forestry and Plant Biology Departments. Those researches have been conducted along the existent trails randomly distributed in the forest or along new trails opened according to the research needs or the scientists' convenience. This management system imposes difficulties or even prevents the proper mapping of sampling locations, the temporal and spatial monitoring of animal and plant communities, and the repeatability of experiments. This paper describes a recently opened 40 ha trail grid system at the CPMP. The grid is composed by five parallel 1,000 m trails and eleven 400 m trails encompassing 40 squares of one hectare. The CPMP is now one of the few Brazilian forest research stations with a trail grid system, which allows scientists to conduct research in many different areas. This work highlights the urgency of trail maintenance and its proper, permanent marking, as well as its georeferencing and its expansion to encompass 100 hectares in order to meet international standard among other research stations in the Neotropics.

Description
An account of the resource
La costra biológica del suelo (CBS) es una comunidad biótica formada por la íntima asociación entre partículas de suelo, cianobacterias, algas, hongos, líquenes, hepáticas y briófitos. La CBS está ampliamente distribuida en muchos tipos de suelo y en casi todas las comunidades vegetales donde la luz alcanza la superficie del suelo, si bien predomina en zonas áridas, semiáridas, alpinas y polares. Este conjunto de organismos proporciona un aporte importante de carbono y nitrógeno al suelo, incrementa su estabilidad y lo protege frente a la acción erosiva de la lluvia y el viento. También modula la infiltración y afecta de manera directa a las plantas vasculares y otros organismos. El conocimiento de la biología, ecología y fisiología de la CBS ha aumentado ampliamente en los últimos años. No obstante, existe un vacío de información importante respecto a la influencia de la CBS en los ciclos biogeoquímicos, especialmente del fósforo y carbono, así como a todo lo referente a las interacciones bióticas, tanto entre los componentes de la CBS entre sí como entre la CBS y los microorganismos, plantas vasculares e invertebrados. Es necesario descentralizar la información y extenderla a otras áreas del mundo, ya que la mayoría de los estudios se han realizado en zonas áridas y semiáridas de los Estados Unidos de América, Australia, Israel y China. Es especialmente preocupante la falta de estudios en toda América Central y del Sur, pese a que la CBS debe ser un componente biótico de primera magnitud en países como Chile, Argentina, Perú y México, por citar solo unos ejemplos. Con el fin de despertar el interés de la comunidad científica de habla hispana sobre este importante conjunto de organismos, y de identificar los principales avances y lagunas existentes en nuestro conocimiento sobre su ecología, en el presente trabajo revisamos las características y distribución de la CBS, así como sus efectos en la estructura y funcionamiento de los ecosistemas en los que se encuentran.Biological soil crusts (BSCs) result from an intimate association between soil particles and cyanobacteria, algae, microfungi, lichens, and bryophytes. These crusts are widespread in many type of soils and in almost all plant communities where sunlight can reach the soil surface. However, BSCs are particulary dominant in environments with low productivity such as arid, semi-arid, alpine and polar areas. Biological soil crusts affect soil nutrient cycling, influence the local hidrological cycle, increase soil stability, and affect the establisment and performance of vascular plants. The knowledge on the biology, ecology and physiology of BSCs has substantially increased in recent years. However, there are important gaps in our knowledge concerning the influence of BSCs on biogeochemical cycles, particularly of phosphorus and carbon, as well as on many aspects related to biotic interactions among BSC components, and between these components and microorganisms, vascular plants and invertebrates. It is necessary to expand current research efforts to other parts of the world, as most studies have been conducted mainly in arid and semi-arid areas of USA, Israel, Australia and China. Of particular concern is the lack of studies from Central and South America, despite BSCs must be a key biotic component in countries such as Chile, Argentina, Peru and Mexico. With the aim of increasing the interest of the scientific community of Spanish-speaking countries about this important group of organisms, in this review we illustrate recent advances on the importance of BSCs to maintain the structure and functioning of those ecosystems in which they are present. We also highlight the main gaps in our knowledge on the ecology of these organisms, and discuss key areas for future research.

INTRODUCCIÓN: La Nanotecnología es un campo de las Ciencias Aplicadas enfocado al diseño, síntesis, caracterización y aplicación de materiales y dispositivos en una escala nanométrica (1 y 100 nm). Es una ciencia muy joven, su desarrollo como disciplina comenzó a finales de la década de los 90 del pasado siglo. Por definición es transdisciplinaria, se aplica en la industria, agricultura, biología, física, química, farmacia, ecología, informática, entre otras A pesar de que solo se viene trabajando en ella hace poco más de 10 años, promete revolucionar el mundo que conocemos. OBJETIVO: Describir los aspectos generales de la Nanotecnología y algunas de sus aplicaciones en la medicina. MÉTODO: Se realizó una revisión de la literatura científica, en idioma inglés, fundamentalmente. Se consultaron las bases de datos de Scielo, Pubmed central, Lilacs y Medline. Escogiéndose los trabajos a texto completo de las revistas de reconocido prestigio. RESULTADOS: Se brindan los aspectos más generales de la Nanotecnología, los nanomateriales y las aplicaciones más importantes del campo de la Medicina. CONCLUSIONES: la Nanotecnología tiene importantes aplicaciones en diagnóstico y tratamiento de enfermedades que constituyen un verdadero reto a la comunidad médica como lo es el cáncer, con la prometedora ventaja de tratar directamente el tejido dañado y no tejido sano, con escasos o pocos efectos colaterales.INTRODUCTION: The nanotechnology is a field of the applied sciences focused to the design, synthesis, characterization and application of materials and devices in a nanometric scale (1 to 100 nm). it is a very young science, its development as discipline it began at the end of the decade of 90 in last century. By definition it is transdisciplinary, it is applied in the industry, agriculture, biology, physics, chemistry, pharmacy, ecology, computer science, between other although alone one comes having worked more thanfor ten years in the same one this science promises to revolutionize the world that we know. OBJECTIVE: To describe the general aspects of the nanotechnology and some of their applications in the medicine. METHOD: Our study consists on an exhaustive bibliographical revision between the months of January of 2010 and March of 2011 of the modernized literature so much printed as digital of the topic in question. RESULTS: The most general aspects in the nanotechnology, the nanomaterial and the most important applications in the field of the medicine are offered. CONCLUSIONS: We have been able to see their important applications in diagnosis and treatment of illnesses that constitute a true challenge to the medical community as it is it the cancer, with the promising advantage of treating the damaged fabric directly and not healthy fabric, with scarce or few colateral effects.

Description
An account of the resource
The seasonal variation of diatoms in the inshore waters off Paraná State, Southern Brazil was investigated to analyse their temporal dynamics and to detect the main environmental constraints of the planktonic community. Biomass peaks occurred from May to August and from December to March. Among the microplanktonic diatoms, Cerataulina pelagica, Chaetoceros spp., Dactyliosolen fragilissimus, Guinardia striata, Lauderia annulata, Leptocylindrus spp., Pseudo-nitzschia cf. delicatissima, P. australis, Rhizosolenia spp., Skeletonema costatum and Thalassionema nitzschioides were dominant species. Nanoplanktonic diatoms were dominated by Naviculaceae, Nitzschia spp., Thalassiosira spp. and Chaetoceros cf. tenuissimus. Concentrations of most of the species decreased during and just after the blooms of Phaeocystis pouchetii in September and of Coscinodiscus wailesii in April. Based on cluster analysis and interpretations of the environmental parameters monitored, six diatom associations were discerned. Four main environmental factors were attributed as the determinants for the grouping: (a) the stronger influence of the tropical oligotrophic waters of the Brazil Current in spring/summer, (b) the alternation between dry and rainy (nutrient-richer) seasons, (c) the influence of subantarctic waters mixed with coastal ones in fall/winter, bringing cold species and promoting the growth of autochthonous species, and (d) the blooms of nanoplanktonic (Phaeocystis) and microplanktonic (C. wailesii) species.A variação sazonal das diatomáceas em águas neríticas do estado do Paraná, Sul do Brasil, foi investigada para analisar sua dinâmica temporal e detectar as principais forçantes ambientais da comunidade planctônica. Picos de biomassa ocorreram de Maio a Agosto e de Dezembro a Março. As espécies dominantes foram Cerataulina pelagica, Chaetoceros spp., Dactyliosolen fragilissimus, Guinardia striata, Lauderia annulata, Leptocylindrus spp., Pseudo-nitzschia cf. delicatissima, P. australis, Rhizosolenia spp., Skeletonema costatum e Thalassionema nitzschioides. Representantes de Naviculaceae, Nitzschia spp., Thalassiosira spp. e Chaetoceros cf. tenuissimus dominaram as diatomáceas nanoplanctônicas. As concentrações da maioria das espécies decresceram durante e logo após as florações de Phaeocystis pouchetii em Setembro, e de Coscinodiscus wailesii em Abril. Com base na análise de cluster e interpretações dos parâmetros ambientais monitorados, seis associações de diatomáceas foram discernidas. Quatro fatores ambientais principais foram atribuídos como determinantes para o grupamento: (a) influência mais forte de águas oligotróficas da Corrente do Brasil na Primavera/Verão, (b) alternância entre as estações chuvosa (rica em nutrientes) e seca, (c) influência de águas subantárticas enriquecidas misturadas às costeiras no Outono e Inverno, trazendo espécies de águas frias, além de promover o crescimento de autóctones, e (d) florações de espécies nanoplanctônicas (Phaeocystis) e microplanctônicas (C. wailesii).

Description
An account of the resource
In this work the infestation with I. luciae on Didelphimorphia and Rodentia in different environments of Peruvian Amazon was studied. Didelphimorphia was represented by the family Didelphidae. Specimens belonging to Caluromys lanatus, Didelphis marsupialis, Marmosops sp.2, Metachirus nudicaudatus, Philander andersoni and Philander opossum were infested with adults I. luciae and one Micoureus sp. was infested with larvae. In Rodentia, the infestation with I. luciae nymphs was restricted to Hylaeamys perenensis, Hylaeamys yunganus and Oligoryzomys microtis, while one Oecomys bicolor (all Cricetidae) was infested with larvae of this species. The few larvae were found on rodents captured in primary forest. The only significant difference (P < 0.05) in prevalence of adult ticks on Didelphimorphia was between P. andersoni and M. nudicaudatus (chi-square distribution). Adult tick distribution was significant different in P. andersoni in comparison with M. nudicaudatus, P. opossum and D. marsupialis (Kruskal-Wallis test). No significant effect of month or environment was detected in relation to adult tick infestation on Didelphimorphia. The prevalence of nymphal infestation as well as tick distribution showed that H. perenensis and H. yunganus were significantly more prone to be infested with nymphs of I. luciae than O. microtis. Prevalence of nymph infestation was higher in primary and secondary forest than rural areas while abundance was higher in secondary forest when compared with rural areas (P < 0.05). Kruskal-Wallis test showed differences (P < 0.05) for nymphal infestation during December in relation to January, March, April and June. The natural cycle of I. luciae appeared to be continuous, bound to adult tick infestation on Philander and nymphal infestation on Hylaeamys in forested environs.No presente trabalho, infestações por Ixodes luciae em Didelphimorphia e Rodentia em diferentes ambientes da Amazônia peruana foram estudadas. Didelphimorphia foi representada pela família Didelphidae. Espécimes pertencentes a Caluromys lanatus, Didelphis marsupialis, Marmosops sp., Metachirus nudicaudatus, Philander andersoni e Philander opossum foram encontrados infestadas por adultos de I. luciae; um Micoureus sp. foi encontrado infestado por larvas. Em Rodentia, a infestação por ninfas de I. luciae estiveram restritas a Hylaeamys perenensis, Hylaeamys yunganus e Oligoryzomys microtis, enquanto que um Oecomys bicolor (todos Cricetidae) esteve infestado por larvas de I. luciae. As poucas larvas foram encontradas em roedores capturados na floresta primária. A única diferença significante (P < 0.05) na prevalência de carrapatos adultos em Didelphimorphia foi entre P. andersoni e M. nudicaudatus (distribuição chi-quadrado). A distribuição de carrapatos adultos foi significativamente diferente em P. andersoni quando comparado com M. nudicaudatus, P. opossum e D. marsupialis (teste Kruskal-Wallis). Nenhum efeito significante do mês ou ambiente foi observado em relação à infestação por carrapato adulto em Didelphimorphia. Tanto a prevalência de infestações por ninfas, como a distribuição do carrapato indicaram que H. perenensis e H. yunganus estiveram mais propensos a estarem infestados por ninfas de I. luciae do que O. microtis. A prevalência de infestações por ninfas foi maior em florestas primária e secundária do que em áreas rurais, enquanto que a abundância foi maior em floresta secundária, quando comparada com áreas rurais (P < 0.05). O teste Kruskal-Wallis indicou diferenças (P < 0.05) para infestações por ninfas durante Dezembro, em relação a Janeiro, Março, Abril e Junho. O ciclo natural de I. luciae parece ser continuo, destacado por adultos parasitando Philander e ninfas parasitando Hylaeamys em ambientes florestais.
