Tendencias espacio-temporales en las capturas accidentales de tortuga boba (Caretta caretta) en la costa catalana entre los años 2000 y 2009

Se describen las tendencias en las capturas accidentales de tortuga boba (Caretta caretta) a lo largo de la costa catalana (Mediterráneo occidental) a partir de los datos del Centro de Recuperación de Animales Marinos de Cataluña. En Girona, la provincia más septentrional y base de la fracción mayor de la flota pesquera de Cataluña, es donde se produce un mayor número de capturas accidentales de esta especie. La mayoría de estas capturas se dan en los meses de verano, coincidiendo con el mayor esfuerzo pesquero del año. La gran mayoría de los individuos son capturados vivos, siendo el palangre el aparejo que provoca más de la mitad de las capturas incidentales en esta región. ABSTRACT: Trends in the loggerhead turtle (Caretta caretta) captured along the Catalonian coasts (Western Mediterranean) are described using data collected by the Marine Animal Rescue Centre of Catalonia. Girona, the most northerly province and base of the greater fraction of the fishing fleet of Catalonia, is the area where the greater part of loggerhead turtle was captured, particularly during the summer, coinciding with the higher fishing effort season. The majority of individuals were caught alive, and the longline appeared to be the fishing gear that causes more than half of the incidental captures in this region

Contaminación por pesticidas en la población canaria: efectos sobre la salud

[ES]El modelo de producción de alimentos desarrollado en la segunda mitad del siglo XX en Canarias (y el resto del mundo) y mantenido en la actualidad ha ido encaminado a incrementar la producción y reducir las pérdidas de producción mediante el uso de plaguicidas. Sin embargo, este tipo de producción intensiva no ha tenido en cuenta el impacto de estas prácticas agrícolas sobre el medio ambiente y la población. El uso y abuso de los plaguicidasha tenido como consecuencia frecuente la contaminación de suelos y acuíferos, y más tarde, la introducción de estos contaminantes en la cadena alimentaria, incorporándose a todos los seres vivos (incluida la especie humana) a través de los alimentos. Estudios de nuestro Grupo de Investigación han confirmado la presencia de residuos de plaguicidas en suelos, aguas, alimentos de nuestras Islas y, lo que es más grave, en sangre y tejidos de la población canaria. Así, se ha demostrado que el 99% de la población delarchipiélago canario presenta residuos de plaguicidas en sangre y, lo que es más llamativo, que las mujeres embarazadas de estas islas presenta residuos de plaguicidas en el líquido amniótico. Por tanto, nuestra exposición a estos contaminantes tóxicos comienza antesdel nacimiento y es continuada a lo largo de toda nuestra vida. Esta situación es extensiva al resto de la población del mundo occidental (incluyendo la española). A día de hoy sabemos que esta exposición continua e ininterrumpida a plaguicidas da lugar a efectos tóxicos a largo plazo (crónicos) pudiendo afectar la salud de la población y sus descendientes. Los mecanismos por lo que pueden afectar a la salud son múltiples, bien sea porque alteran, a) el sistema hormonal (se relacionan con alteraciones reproductivas en el hombre y la mujer, con el incremento de incidencia de diabetes, tumores hormonodependientes como mama o testículo, y con alteraciones en la función tiroidea); b) el sistema cardiovascular (alterando la tensión arterial y el funcionalismo cardiaco); c) el metabolismo (algunos favorecen el desarrollo obesidad, esto es, son obesogénicos), o d) el sistema Nervioso Central (relacionándose la exposición crónica a plaguicidas con alteraciones neurocognitivas o retraso en el desarrollo en niños, o con enfermedades neurodegenerativas como Parkinson y Alzheimer en el adulto). En resumen, la contaminación de nuestro medio ambiente, y, por tanto de nuestra población, por plaguicidas no nos sale gratis y nos pasa o pasará factura en salud.

Quimeras de oriente: Edith Wharton en Marruecos

[ES]En In Morocco (1919), Edith Wharton relata la crónica de un viaje realizado por el Marruecos colonial de finales de la Primera Guerra Mundial. Con el sentido del tiempo que le inspira el paisaje magrebí, Wharton reinterpreta la historia de Marruecos acercándonos un país con un pasado que parece estar vivo. Su recorrido presenta una doble vertiente: por un lado, Wharton no pierde detalle de las imágenes de miseria y sordidez que forman parte de los estereotipos coloniales del viajero occidental; por otro, el romance que encierra In Morocco, el crisol orientalista y la visión de Las mil y una noches que se percibe en su impresiones, revisten el relato de una mirada mágica y fantasiosa que difiere de la realidad del país.

Altinópolis, una utopia brasiliana. Analisi di una esperienza di educazione alla pace e non violenza come pratica alternativa dell'educazione popolare

The present thesis has as its object of study a project called “Education towards Peace and No Violence”, developed in the town of Altinópolis, in the inner part of the state of São Paulo, Brazil. Based on the analysis and the studies that were carried out, it was possible to identify the difficulties in the implementation of the project, as well as the positive results evidenced by the reduction of the reports of violence in the town. Through a careful research of the historical facts, it shall be demonstrated the progress of education, particularly in Brazil, throughout the years. In addition, a panoramic view of the studies and programs for peace developed in North America and Occidental Europe will be presented. The education for peace based in the holistic concept of human development appeared as a new educational paradigm that works as a crucial instrument in the construction process towards a peaceful and more human society based in social justice.

Catálogo comentado de los pelecípodos canarios del Museo

[ES] Son unas doscientas las especies de Pelecípodos que, o bien han sido citados alguna vez de las islas Canarias o bien el archipiélago queda incluido en su área biogeográfica, aunque de hecho su existencia no se haya comprobado nunca en las islas. El número es algo bajo, pues tanto de la Costa occidental de África (Cabo Verde) como de Portugal, llega a trescientas el número de especies conocidas. Además se observa en Canarias una marcada falta de personalidad de su fauna de Pelecípodos pues aproximadamente un 88% es común al Mediterráneo, un 45% es común a la región de Guinea, un 34% son comunes con el Mediterráneo y con Guinea, y sólo un dos por ciento es propio de las aguas de Canarias faltando en el Mediterráneo y en la costa africana al sur de Mauritania.

Los niveles con strombus de Jandia (Fuerteventura, Islas Canarias)

[ES] En 1890 (pág. 714), Rothpletz y Sirnonelli, al estudiar la fauna del Mioceno de Las Palmas, citan el Strombus coronatus de las localidades siguientes Fuerteventura-Lomo Blanco, La Vista, Ba- rrancos (Gran Canaria). En 1956, Hausen (pkg. 35), en una nota infrapaginal, da cuenta del hallazgo de un Strombus coronatus realizado por don Simón Benítez Padilla en Morro Jable (Jandía), a 55 metros de altura. Crofts, en 1965, es el primero en realizar un estudio más detenido de los niveles marinos de Fuerteventura, pero se limita a un tramo de 40 kilómetros de la costa noroccidental. Describe niveles marinos a 55, 35, 23, 16, 7 y 2 metros, los compara con los datos de la costa occidental de África y deduce una estabilidad total de Fuerteventura durante el Cuaternario.

La governance della società di capitale a base familiare: "Protocolo Familiar" e Patti di Famiglia

Family businesses have acquired a very specific gravity in the economy of occidental countries, generating most of the employment and the richness for the last ages. In Spain Family Businesses represent the 65% about the total of enterprises with 1,5 million companies. They give employment to 8 million people, the 80% of the private employment and develop the 65% of the Spanish GNP (Gross National Product). Otherwise, the family business needs a complete law regulation that gives satisfaction to their own necessities and challenges. These companies have to deal with national or international economic scene to assure their permanency and competitiveness. In fact, the statistics about family companies have a medium life of 35 years. European family businesses success their successor process between a 10 and 25%. It’s said: first generation makes, second generation stays, third generation distributes. In that sense, the Recommendation of the European Commission of December 7º 1994 about the succession of the small and medium companies has reformed European internal orders according to make easier successor process and to introduce practices of family companies’ good government. So, the Italian law, under the 14th Law, February 2006, has reformed its Covil Code, appearing a new concept, called “Patto di famiglia”, wich abolish the prohibition as laid dwon in the 458 article about successors’ agreements, admitting the possibility that testator guarantees the continuity of the company or of the family society, giving it, totally or in part, to one or various of its descendents. On other hand, Spain has promulgated the 17th Royal Decree (9th February 2007), that governs the publicity of family agreements (Protocolos familiars). These “protocolo familiar” (Family Agreement) are known as accord of wills, consented and accepted unanimously of all the family members and the company, taking into account recommendations and practices of family company’s good government.

Spatio-temporal variation of macrofaunal assemblages in the deep Blanes submarine canyon

The spatio-temporal variations in diversity and abundance of deep-sea macrofaunal assemblages (excluding meiofaunal taxa, as Nematoda, Copepoda and Ostracoda) from the Blanes Canyon (BC) and adjacent open slope are described. The Catalan Sea basin is characterized by the presence of numerous submarine canyons, which are globally acknowledged as biodiversity hot-spots, due to their disturbance regime and incremented conveying of organic matter. This area is subjected to local deep-sea fisheries activities, and to recurrent cold water cascading events from the shelf. The upper canyon (~900 m), middle slope (~1200 m) and lower slope (~1500 m) habitats were investigated during three different months (October 2008, May 2009 and September 2009). A total of 624 specimens belonging to 16 different taxa were found into 67 analyzed samples, which had been collected from the two study areas. Of these, Polychaeta, Mollusca and Crustacea were always the most abundant groups. As expected, the patterns of species diversity and evenness were different in time and space. Both in BC and open slope, taxa diversity and abundance are higher in the shallowest depth and lowest at -1500 m depth. This is probably due to different trophic regimes at these depths. The abundance of filter-feeders is higher inside BC than in the adjacent open slope, which is also related with an increment of predator polychaetes. Surface deposit-feeders are more abundant in the open slope than in BC, along with a decrement of filter-feeders and their predators. Probably these differences are due to higher quantities of suspended organic matter reaching the canyon. The multivariate analyses conducted on major taxa point out major differences effective taxa richness between depths and stations. In September 2009 the analyzed communities double their abundances, with a corresponding increase in richness of taxa. This could be related to a mobilizing event, like the release of accumulated food-supply in a nepheloid layer associated to the arrival of autumn. The highest abundance in BC is detected in the shallowest depth and in late summer (September), probably due to higher food availability caused by stronger flood events coming from Tordera River. The effects of such events seemed to involve adjacent open slope too. The nMDS conducted on major taxa abundance shows a slight temporal difference between the three campaigns samples, with a clear clustering between samples of Sept 09. All depth and all months were dominated by Polychaeta, which have been identified to family level and submitted to further analysis. Family richness have clearly minimum at the -1200 m depth of BC, highlighting the presence of a general impact affecting the populations in the middle slope. Three different matrices have been created, each with a different taxonomic level (All Taxa “AT”, Phylum Level “PL” and Polychaeta Families “PF”). Multivariate analysis (MDS, SIMPER) conducted on PL matrix showed a clear spatial differences between stations (BC and open slope) and depths. MDSs conducted on other two matrices (AT and PF) showed similar patterns, but different from PL analysis. A 2 nd stage analysis have been conducted to understand differences between different taxonomic levels, and PL level has been chosen as the most representative of variation. The faunal differences observed were explained by depth, station and season. All work has been accomplished in the Centre d’estudis avançats de Blanes (CEAB-CSIC), within the framework of Spanish PROMETEO project "Estudio Integrado de Cañones y Taludes PROfundos del MEdiTErráneo Occidental: un hábitat esencial", Ref. CTM2007-66316-C02- 01/MAR.

External drivers of biogeochemical cycles in a tropical montane forest in Ecuador

Successful conservation of tropical montane forest, one of the most threatened ecosystems on earth, requires detailed knowledge of its biogeochemistry. Of particular interest is the response of the biogeochemical element cycles to external influences such as element deposition or climate change. Therefore the overall objective of my study was to contribute to improved understanding of role and functioning of the Andean tropical montane forest. In detail, my objectives were to determine (1) the role of long-range transported aerosols and their transport mechanisms, and (2) the role of short-term extreme climatic events for the element budget of Andean tropical forest. In a whole-catchment approach including three 8-13 ha microcatchments under tropical montane forest on the east-exposed slope of the eastern cordillera in the south Ecuadorian Andes at 1850-2200 m above sea level I monitored at least in weekly resolution the concentrations and fluxes of Ca, Mg, Na, K, NO3-N, NH4-N, DON, P, S, TOC, Mn, and Al in bulk deposition, throughfall, litter leachate, soil solution at the 0.15 and 0.3 m depths, and runoff between May 1998 and April 2003. I also used meteorological data from my study area collected by cooperating researchers and the Brazilian meteorological service (INPE), as well as remote sensing products of the North American and European space agencies NASA and ESA. My results show that (1) there was a strong interannual variation in deposition of Ca [4.4-29 kg ha-1 a-1], Mg [1.6-12], and K [9.8-30]) between 1998 and 2003. High deposition changed the Ca and Mg budgets of the catchments from loss to retention, suggesting that the additionally available Ca and Mg was used by the ecosystem. Increased base metal deposition was related to dust outbursts of the Sahara and an Amazonian precipitation pattern with trans-regional dry spells allowing for dust transport to the Andes. The increased base metal deposition coincided with a strong La Niña event in 1999/2000. There were also significantly elevated H+, N, and Mn depositions during the annual biomass burning period in the Amazon basin. Elevated H+ deposition during the biomass burning period caused elevated base metal loss from the canopy and the organic horizon and deteriorated already low base metal supply of the vegetation. Nitrogen was only retained during biomass burning but not during non-fire conditions when deposition was much smaller. Therefore biomass burning-related aerosol emissions in Amazonia seem large enough to substantially increase element deposition at the western rim of Amazonia. Particularly the related increase of acid deposition impoverishes already base-metal scarce ecosystems. As biomass burning is most intense during El Niño situations, a shortened ENSO cycle because of global warming likely enhances the acid deposition at my study forest. (2) Storm events causing near-surface water flow through C- and nutrient-rich topsoil during rainstorms were the major export pathway for C, N, Al, and Mn (contributing >50% to the total export of these elements). Near-surface flow also accounted for one third of total base metal export. This demonstrates that storm-event related near-surface flow markedly affects the cycling of many nutrients in steep tropical montane forests. Changes in the rainfall regime possibly associated with global climate change will therefore also change element export from the study forest. Element budgets of Andean tropical montane rain forest proved to be markedly affected by long-range transport of Saharan dust, biomass burning-related aerosols, or strong rainfalls during storm events. Thus, increased acid and nutrient deposition and the global climate change probably drive the tropical montane forest to another state with unknown consequences for its functions and biological diversity.

History of Restoration in Iran: Origins and Developments from 1900 to 1978

This thesis tends to study the origins and developments of the restoration in Iran from its very first moments till the Islamic revolution of 1978. The thesis is its first study of its kind. While almost all recent occidental ideologies regarding the thematic of restoration and conservation of historic monuments are translated and published in Iran, very little efforts have been done regarding the study of the origins of the formation of restoration in the country. The diversity of Iranian contexts, multiplicity of the intervening factors and other factors characterized a different background for the raise and developments of restoration in the country; in the thesis the influencing and characterizing factors in the formation and development of restoration in Iran will be defined and studied in detail with relative examples; due to the complexity of the Iranian context and in order to consider all influencing and characterizing factors the thesis, parallel to have formation and development of restoration, as the main scope of the research, the developments influencing factors will be confronted with necessary flashbacks to the main theme, when and where necessary. A great care will be given to the period of the activity of the restoration experts of IsMEO which is thesis will be called as the period of the introduction of the modern principles of restoration into Iranian context; the fundamental ideologies, practical and theoretical principles of IsMEO will be identified and studied in details; important case of studies of the restoration of IsMEO will be analyzed in details and the innovative aspect of the presence of Italian experts of IsMEO will be revealed.

Le désert et la littérature de voyage européenne du XIXe siècle

L'Europe commence à découvrir le désert à la fin du XVIIIe siècle. Ce milieu présente des aspects multiples aux premiers explorateurs, qui le décrivent comme un lieu vivant et varié. La géopolitique constitue le premier approche d'analyse : le désert peut être rendu plus viable si mieux administré, donc libre de la domination ottomane. Au cours du siècle, le tourisme se développe, aussi en raison de la colonisation ; l'expérience du désert devient commune, et les voyageurs partent en quête d'une expérience spirituelle aussi bien que d'une aventure. Le désert devient un écran de projection pour la rêverie et les souvenirs des Européens (la Bible et les topos traditionnels demeurent actifs dans l'imaginaire occidental) ; seules certaines caractéristiques de ce milieu sont dès lors appréciées par les voyageurs. Ensuite, avec l'âge du Réalisme, devient objet d'appréciation de la part des peintres. Grâce à la médiation de l'art, la littérature commence à regarder au désert d'un point de vue esthétique, et elle lui reconnaît un charme de la nudité et du dépouillement. La mort et le minéral caractérisent ce milieu vers la fin du siècle ; le désert se vide, et devient le "désert de sable" que nous tous connaissons aujourd'hui.
