New insights into the daily and symbolic use of plants during initial occupations of Formentera (Balearic Islands, Spain)
2021
The island of Formentera, with its small extension and flat orography, was settled relatively late in Mediterranean prehistory between the third and second millennium BC. The sites presented in thi...
Testing Taxonomic and Biogeographical Relationships in a Narrow Mediterranean Endemic Complex (Hippocrepis balearica) using RAPD Markers
2002
Analyses of RAPD profiles from 17 populations of the Hippocrepis balearica complex revealed a highly structured geographic pattern, not only among continental–insular areas but also within the eastern Balearic islands. In marked contrast to previous morphometric results, a clear separation between continental and insular samples was found, and intermediates between H. balearica and H. valentina samples were not detected. Molecular data indicated that western and eastern Balearic populations of the complex (H. grosii and H. balearica) were more closely related to each other than to continental populations (H. valentina). Multivariate analyses of the RAPD data clearly indicated that the simil…
The Balearic toad (Bufo viridis balearicus (BOETTGER, 1881)), human bronze age culture, and Mediterranean biogeography
1981
Abstract Microcomplement fixation analysis of albumin relationship shows that the Balearic green toad (Bufo viridis balearicus) is not an original, autochthonous member of the basically Miocene fauna of these western Mediterranean islands, but a quite recent newcomer. The plasma protein pattern clearly points to its close populational relationship to the Tyrrhenian islands' conspecifics. The male and female release vocalization shows the same, and this is in accordance with the external morphology too. There has been no possibility for toads to reach the Balearic Islands in Pleistocene or Holocene via land bridges, nor are they candidates for any sea drifting. Anthropogenic introduction mu…
Typification of the Linnaean name Centaurea seridis (Asteraceae)
2014
The genus Centaurea Linnaeus (1753: 909) (Asteraceae) comprises a large number of taxa mainly occurring in the Mediterranean region and southwest Asia (Susanna & Garcia-Jacas 2007). Centaurea seridis Linnaeus (1753: 915) is distributed from south Europe (Spain incl. Balearic Islands, Italy incl. Sicily, France, Albania and Greece) to northwest Africa (Algeria, Morocco and Tunisia). From a nomenclatural standpoint, Centaurea seridis has not been typified (Jarvis 2007: 402). This paper proposes the designation of a lectotype for this Linnaean name, based on the analysis of the protologue and original material.
Nuclear and chloroplast DNA variation in Cephalaria squamiflora (Dipsacaceae), a disjunct Mediterranean species
2009
Cephalaria squamiflora is a chamaephyte restricted to rupicolous habitats in islands of the Western (Balearic Islands, Sardinia) and Eastern Mediterranean (Crete and few Aegean islands). Four narrowly distributed races (subspp. squamiflora, mediterranea, ebusitana, balearica) have been described to encompass the morphological variation within the species. We have used nuclear ribosomal ITS and cpDNA sequences to assess how the patterns of molecular differentiation are related to taxonomic and geographic boundaries. Extensive intragenomic ITS variation was detected in samples from all territories, the average sequence divergence among cloned ribotypes was 1.339%. The parsimony network of clo…
Short and medium effects on the environment of Valencia, Spain, of the Chernobyl nuclear plant accident.
1991
As a consequence of the 26 April 1986 accident at the Chernobyl nuclear plant, a large amount of radioactivity was released into the atmosphere. The radioactive plume formed could be detected in practically the whole of the Northern Hemisphere a few days later. The zone most affected by the radioactive cloud over Spain was that of the Mediterranean coast and the Balearic Islands. In this paper, the authors examine the level of the radioactive contamination reached in various receptive media in Valencia, such as air, dry-fallout, water, soil, grass and milk samples collected in Valencia immediately after the accident. The activity levels are compared with those found during 1964 and 1965 due…
La expansión geográfica de la renta del tabaco
2007
El monopolio real del tabaco fue decretado sólo para la Corona de Castilla en 1636. Debido a su reconocida eficacia, los gobernantes españoles intentaron implantarlo allá donde fuese políticamente posible. Después de la guerra de Sucesión, fue establecido en la Corona de Aragón, ya que estos territorios perdieron entonces su régimen foral de autonomía. Como las provincias vascas y Navarra consiguieron conservar su régimen foral, el Gobierno español no pudo someter allí el régimen general del estanco tabaquero y tuvo que contentarse con negociar soluciones que no perjudicasen al estanco general. Finalmente, en el contexto de las reformas borbónicas en América, la Renta del Tabaco fue gradual…
A renewable energy mix to supply small islands. A comparative study applied to Balearic Islands and Fiji
2019
Abstract Power plants supplied by renewables are expanding around the world, increasing the sustainability of the energy sector. In this context, small islands are heavily reliant on fossil fuels. However, this paper shows that the same problem can be found also in small islands belonging to developed countries. To increase the energy sustainability of small islands, the authors assembled a simplified mathematical approach to evaluate the potential electricity production, exploiting the local available energy sources: solar, wind and sea wave. The mathematical model requires few information in input, such as climatic data about the local energy sources and technical features on the selected…
Greening and sustainable energy approach applied for Balearic Islands and Fiji Islands: a comparative study
2018
Renewable energy sources are expanding around the world, with significative results in the electricity generation sector. Despite this, the share of renewable energy sources in small islands is very low, except in rare cases. In this context, the paper analyses the energy mix currently used to produce electricity in the Balearic Islands and the Fiji Islands. These two archipelagos show several differences but have in common the strong energy dependence from fossil fuels. In order to increase the energy sustainability of small islands, a preliminary energy assessment is realized, using climate data collected from GIS-tools and introducing a numerical approach. As target, the Authors consider…
De l'Estudi General a la Universitat de les Illes Balears
2020
Resum: L’Estudi General de la Ciutat de Mallorca, creat el 1483, concedia graus en teologia, filosofia i arts, vàlids únicament en el territori de la monarquia hispànica. Des de mitjan segle xvi va haver d’afrontar la competència del col·legi dels jesuïtes. Per superar aquesta pugna sol·licità i obtingué (1673) que el papat reconegués las validesa dels seus títols a tota la cristiandat. Les dificultats econòmiques retardaren el funcionament d’aquesta universitat fins el 1691. Rebé el nom de Universitat Lul·liana de Mallorca. El 1772 passà a denominar-se Universitat Literària de Mallorca. El 1842 se suprimí definitivament. A Mallorca no hi tornà haver estudis universitaris fins a 1967, i el …
