    The composition, diversity, and phytogeographic affinities of the vascular flora of Bolivia\u27s wetlands were examined and compared with wetland floras from the other Neotropical countries and the New World Temperate region. Forty-six wetlands distributed throughout Bolivia and ranging in elevation from 90 in to \u3e4400 m were established as study sites. Regional and national wetland floras were compiled from field research, the literature, herbarium specimens, and available databases. Two thousand and sixty species in 149 families and 666 genera were identified as associated with wetlands in Mesoamerica and tropical and subtropical South America. Of these, 1026 species in 126 families and 450 genera were noted for Bolivian wetlands. When considered both in terms of number of species per system and in comparisons of species-area curves, Bolivia\u27s wetlands were found to be less diverse than wetlands of the New World Temperate region. At the macroregional level, both South and Central America were less diverse than the New World Temperate region. Thus, at both the system and regional scales, it appeared that phytodiversity in New World wetlands constituted an exception to the widely recognized latitudinal gradient in species richness. Additionally, phytodiversity in Neotropical wetlands was generally not well-correlated with diversity in terrestrial habitats. A large portion of the Neotropical wetland species possessed very broad ranges, and few endemic species were noted relative to the Neotropical terrestrial habitats. Similarity Indices were generally unsatisfactory for analyzing floristic similarities at the system level. Both Detrended Correspondence Analysis (DCA) and Frequency Analysis produced more satisfactory results. Species that typically tended towards dominance in Bolivian wetlands most often were extremely widely distributed, precluding the identification of regional wetland associations based on dominant species. Nevertheless, ordination of the study sites by DCA generally grouped wetlands from within the same Bolivian region. At the macroregional level, an ordination by DCA ordered the countries of the Neotropics into three groups: (1) Bolivia, Brazil and Peru; (2) Colombia, The Guianas, and Venezuela; and, (3) all Central American countries. Two countries, Mexico and Ecuador, were not clearly associated with any group

    XVI Colóquio de Outono: conflito e trauma

    It has been the main concern of CEHUM, as a Research Centre within the Humanities which operates in an inter and transdisciplinary structure to listen attentively to the “noise of the world” and attempt a global interpretation of the signs of the times issuing from the world around us, as vibrant echoes of many social and cultural pressing issues. Every year each new Colóquio de Outono attempts to give evidence of that concern through the topic chosen for debate, ample enough and challenging enough to trigger a lively multidisciplinary dialogue amongst the diff erent research groups that compose this centre, the participants and our invited guest speakers. Throughout the three days of this 16th Colóquio de Outono we had the privilege to debate the propositions of a vast number of national and international specialists in the manifold fi elds of inquiry here represented, engaging keynote speakers, project advisors, members of research teams and external researchers attached to the various research projects currently running in CEHUM, in the fi elds of literature, linguistics, philosophy, ethics, visual arts, cultural studies, music and performance. Each specifi c fi eld of studies was however never seen isolated, but always embodied in a geo-cultural context and within the scope of a wide variety of critical debates and current theories of knowledge, as a signal of our understanding of the Humanities as a rich and plural territory which engages us all, scholars, researchers, students.FCT, QREN, COMPETE, U

    Programa de Doctorado en Recursos y Tecnologías Agrarias, Agroambientales y AlimentariasEl binomio agua-energía es uno de los motores de la agricultura y del desarrollo de la civilización. En el levante español, la agricultura sostenible se remonta al pueblo musulmán, los cuáles transmitieron los conocimientos provenientes de Oriente aprovechando la energía del agua para elevarla a las tierras de mayor altitud, mediante el uso de norias y otros ingenios similares. De este modo transformaban las tierras de secano en productivas tierras de regadío. Toda la cuenca del Segura, en particular los agricultores del Sureste Español han conservado y mejorado las instalaciones hidráulicas que heredaron. Estos agricultores, no se conforman con producir las mejores frutas y verduras de Europa. Mediante modernas tecnologías, como el Internet de las Cosas (IoT) y la innovación mediante el uso de sensores, están desarrollando una agricultura de primer nivel. En esta tesis se muestran diversos casos de estudio relacionados con recientes avances en aplicación de Tecnologías de la Información y la Comunicación (TIC). Estos avances son aplicados a la agricultura de precisión de manera eficiente, mediante la implementación de un sistema Smart-Agri. Asimismo, este sistema es capaz de utilizar la energía fotovoltaica para la extracción de aguas subterráneas. Adicionalmente, el sistema permite transportar aguas regeneradas de las EDAR de las zonas urbanas a los embalses de cabecera, con el fin de proporcionarle una energía suficiente para su empleo en riego de precisión. Simultáneamente este sistema incluye un análisis de la calidad del agua suministrada en tiempo real. Todo ello garantiza cultivos de calidad sostenible y es respetuoso con el medio ambiente. Esta tecnología se basa en sistemas de comunicación de bajo coste con radio de baja frecuencia (LowRa). En estos sistemas se aplica una gobernanza enmarcada dentro de los objetivos de desarrollo sostenible (ODS). El fin es reducir la desertificación de estas tierras cultivables que están en peligro de abandono por su baja producción. Como consecuencia se reduce la huella hídrica y de los Gases de Efecto Invernadero (GEI), de la Agenda 2030 de las Naciones Unidas. Estos pulmones verdes artificiales proporcionan, no sólo alimentos para la Unión Europea, sino que también son un sumidero de CO2 que contribuye a la protección de la capa de ozonoThe water-energy binomial is one of the engines of agriculture and the development of civilization. In the Easter Spain, sustainable agriculture dates back to the Muslim culture, who transmitted the knowledge from the East taking advantage of the energy of the water to raise it to the higher lands, using waterwheels and other similar devices. In this way, they transformed rainfed lands into productive irrigated lands. The entire Segura basin, particularly the farmers of the Spanish Southeast, have conserved and improved the hydraulic installations they inherited. These farmers are not satisfied with producing the best fruits and vegetables in Europe. Using modern technologies, such as the Internet of Things (IoT) and innovation through the use of sensors, they are developing firstrate agriculture. This thesis shows various case studies related to recent advances in the application of Information and Communication Technologies (ICT). These advances are applied to precisión agriculture in an efficient way, through the implementation of a Smart-Agri system. Also, this system is capable of using photovoltaic energy to extract groundwater. Additionally, the system allows the transport of reclaimed water from the WWTP in urban areas to the headwater reservoirs, in order to provide it with sufficient energy for its use in precision irrigation. Simultaneously this system includes an analysis of the quality of the water supplied in real time. All this guarantees crops of sustainable quality and it is respectful with the environment. This technology is based on low-cost communication systems with low frequency radio (LowRa). In these systems a governance framed within the Sustainable Development Goals (SDG) is applied. The aim is to reduce the desertification of these arable lands that are in danger of abandonment due to their low production. As a consequence, the water footprint and Greenhouse Gases (GHG) footprint of the United Nations 2030 Agenda is reduced. These artificial green lungs provide, they are not only food for the European Union, but they are also a CO2 sink that contributes to the protection of the ozone laye

    Proceedings of the International Congress on Interdisciplinarity in Social and Human Sciences

    Get PDF
    Interdisciplinarity is the main topic and the main goal of this conference. Since the sixteen century with the creation of the first Academy of Sciences, in Napoles (Italy) (1568), and before that with the creation of the Fine Arts Academies, the world of science and arts began to work independently, on the contrary of the Academy of Plato, in Classical Antiquity, where science, art and sport went interconnected. Over time, specific sciences began to be independent, and the specificity of sciences caused an increased difficulty in mutual understanding. The same trend has affected the Human and Social Sciences. Each of the specific sciences gave rise to a wide range of particular fields. This has the advantage of allowing the deepening of specialised knowledge, but it means that there is often only a piecemeal approach of the research object, not taking into account the its overall complexity. So, it is important to work for a better understanding of the scientific phenomena with the complementarity of the different sciences, in an interdisciplinary perspective. With this growing specialisation of sciences, Interdisciplinarity acquired more relevance for scientists to find moreencompassing and useful answers for their research questions.info:eu-repo/semantics/publishedVersio

    The Janus-Faces of Cross-Border Crime in Europe

    Get PDF
    Europe is changing rapidly, which may also have a bearing on its criminal landscape. This does not mean that all sorts of new crime are emerging: a large part of the crimes remains profit-oriented and is committed by known modus operandi. That is the old face of crime. Amidst the traditional landscape new faces of crime can be identified. The internet is such a new face which emerges among others in the sex industry. This is as old as the human race, with all the related abuses and exploitation. But the internet gives it also a new face because of its broad reach and related opportunities, negative as well as positive. This volume provides other examples of this two-faced Janus head of crime. Old criminal trades, such as the illegal cigarette market, synthetic drugs and criminal exploitation of human labour, but also new criminal specialisations, new professional and industrial skills developed by ‘old’ ethnic minorities on various crime markets in central Europe. Meanwhile, the on-going illegal migrations continue to exert their influence on the perception of crime: while the actual prevalence of most types of crime decreases, fear of crime continues to increase. The flow of migrants is unrelated to this outcome but it impacts nevertheless on the perception of crime. This volume of the 18th Cross-border Crime Colloquium, held in Bratislava in the spring of 2017, contains the peer-reviewed contributions of 22 European experts and up-and-coming researchers. Their chapters cover a broad field of crime in which the double faced Janus head can be discerned: illegal migrants, criminal markets, corruption, money laundering and organised crime, highlighting many new aspects

    This paper investigates transitional states of spaces between images, moving images, and the use of sketchbook/page works through a questioning and auto-ethnographic approach to research and practice. Viewing illustration as a refexive space, the investigations demonstrate exchangesbetween authorship, interaction, narrative, time, and space. Valuing the ‘in-between’ states that exist between the unfnished and fnished, the research questions notions of in-fux, moving, nebulous states. Through alternative publishing forms, the research concerns dissemination through emerging digital platforms
