Hotspots of species richness, threat and endemism for terrestrial vertebrates in SW Europe
2011
The Mediterranean basin, and the Iberian Peninsula in particular, represent an outstanding “hotspot” of biological diversity with a long history of integration between natural ecosystems and human activities. Using deductive distribution models, and considering both Spain and Portugal, we downscaled traditional range maps for terrestrial vertebrates (amphibians, breeding birds, mammals and reptiles) to the finest possible resolution with the data at hand, and we identified hotspots based on three criteria: i) species richness; ii) vulnerability, and iii) endemism. We also provided a first evaluation of the conservation status of biodiversity hotspots based on these three criteria considerin…
Climate change and human impact in central Spain during Roman times: High-resolution multi-proxy analysis of a tufa lake record (Somolinos, 1280m asl)
2012
The Roman Period is considered a crucial phase in the evolution of Holocene landscapes, due to the coincidence of major climatic, environmental, economic and cultural changes. However, there is still debate as to the regional expression of these changes, and to the mechanisms involved, particularly in the topographically and climatically complex region of the Mediterranean. In order to improve our understanding of the synergies between societal and environmental change during this period in central Spain, we present a comprehensive case study based on the integration of multi-proxy palaeoenvironmental, archaeological and historical data. High-resolution, interdisciplinary research has been …
Middle Miocene foraminifera from Canals (Valencia, western Mediterranean). Biostratigraphic and palaeoenvironmental aspects
2020
The age and the palaeoenvironmental conditions of the tap marls outcroppings near the locality of Canals in the south of the Valencia Province (E Spain) are discussed. Based on the planktonic foraminifera assemblages, mainly the species Globorotalia praemenardii , these tap marls are dated as Serravallian in age (middle Miocene). The analysis of the foraminiferal assemblages suggests a relatively well-ventilated uppermiddle bathyal environment, with only a moderate oxygen deficiency throughout most of the studied section. The rather cool waters indicated by the planktonic foraminifera (e.g. Globigerina bulloides ) are compatible with the decreasing temperatures trend during the middle Mioce…
Anisakid Nematodes and Potential Risk of Human Anisakiasis through the Consumption of Hake, Merluccius spp., Sold Fresh in Spanish Supermarkets
2022
Nematode parasite species belonging to the Anisakis simplex complex are the most important cause of human anisakiasis through the consumption of (mainly) undercooked, previously not frozen, or conveniently treated fish. In Spain, the consumption of hake has been recognized as an important source of this parasitosis. With the aim of shedding light on the risk factors that can influence the potential risk of human anisakiasis in Spain through the consumption of fresh hake sold by nationwide supermarket chains, a total of 536 small hake specimens belonging to the species Merluccius bilinearis caught off the Northeast American coasts and Merluccius merluccius caught in the Northeast Atlantic an…
Gracia y gobierno en la administración valenciana del seiscientos. Hacia nuevos consensos
2015
Desde 1645 dos miembros de la nobleza local entraron a formar parte de la sala criminal de la Audiencia valenciana. Como consejeros de capa y espada asumieron competencias en materias de gracia y gobierno. Con esta medida se introdujo una moderación del arbitrio virreinal en tales ejercicios. Pero, sobre todo, la corona convirtió a la pequeña y mediana nobleza del reino en nueva colaboradora de su política de control estamental. From 1645 two members of the local nobility came to form part of the Criminal Chamber of the Valencian audience. As Ministers of «capa y espada» took powers in matters of Grace and Government. This measure was introduced a moderation of the Viceregal discretion in s…
Characterization of the land snail Ganula lanuginosa (Boissy, 1835) (Mollusca: Hygromiidae): new invader of the Iberian Peninsula.
2021
Recently, a well-established population of the hygromiid Ganula lanuginosa has been discovered in the Iberian Peninsula, specifically in Xàtiva (Province of Valencia, Spain), corresponding to the first record for the Iberian Peninsula and the Continental Europe. It is a land snail native to North Africa and also known from the European Mediterranean islands, namely the Balearic Islands (Spain), Sardinia (Italy) and Corsica (France). Morpho-anatomical studies of the shell and the reproductive system have been carried out, and these features have been compared with those of the most similar hygromiids, which has allowed us to correctly identify them. In addition, parasitological and ec…
Una nación descamisada : Ortega y Gasset y su idea de España durante la Primera Guerra Mundial (1914-1918)
2015
Ortega dedicó una atención algo escasa a la Primera Guerra Mundial en sus escritos. Pero para él la guerra fue una posibilidad de pensar la posibilidad de regeneración de la nación española . Estuvo menos interesado en escoger campos entre los aliados o Alemania que en lamentar los efectos de la neutralidad para España (en 1914 como en 1918). Esta equidistancia revisable fue, además, su manera de crearse un lugar en el campo de fuerzas intelectual y en la esfera política.Ortega insistió siempre en que la neutralidad, si era fruto de la debilidad, era la peor cosa que podía sucederle a España, pues la condenaba a la periferia de la toma de decisiones internacionales. Era causa y a la vez efe…

2005
Miguel.Gomez@uv.es Olga.Mayoral@uv.es Se aportan los primeros datos sobre la presencia de Euonymus latifolius en la Comunidad Autónoma de Castilla-La Mancha (España). La población hallada se encuentra próxima a las hoces del río Tajo en Cuenca y está compuesta por 32 ejemplares, de los cuales sólo 2 son adultos. We found the first population of Euonymus latifolius in Castilla-La Mancha region (Spain) near the river Tajo in Cuenca province with only 32 plants, 2 of which are adults.
LOCHKOVIAN TO PRAGIAN (LOWER DEVONIAN) NERITIC OSTRACODES FROM NIGÜELLA (ZARAGOZA, IBERIAN CHAINS, NE SPAIN)
2021
Lochkovian and Pragian ostracodes from the area of Niguella (Iberian Chains), which is a key area for supra-regional correlation in the Early Devonian, are described for the first time. 12 ostracode taxa from the sections Ni4 and Ni2 could be identified. The silicified ostracodes of Eifelian Ecotype are low in biodiversity, have few individuals, and are comparatively poorly preserved. Characteristic taxa of the Devonian occur. Thus, the faunas show general relations to most European Early Devonian ostracode faunas. Closer relations exist to the Eastern Guadarrama. Polyzygia kroemmelbeini LeFevre & Weyant, 1967 and P. grekoffi Weyant, 1980 are found in the basal Pragian for the first time. B…
Prehistoric land use at an archaeological hot-spot (the rock art park of Campo Lameiro, NW Spain) inferred from charcoal, synanthropic pollen and non…
2013
Pollen, non-pollen palynomorphs and charcoal from a colluvial soil surrounded by prehistoric petroglyphs (Campo Lameiro, NW Spain) were studied in order to assess the nature of human activities and their impact on Holocene vegetation patterns. Several phases of anthropogenic impact were observed. (i) Between 7.6 and 6.5 ka cal BP, synanthropic taxa (Urtica dioica type, Plantago lanceolata type) and coprophilous fungi (e.g. Sporormiella-type) are indicative of early (pre-agricultural) creation of small patches of pasture using fire, possibly for incipient animal husbandry or as part of a deliberate strategy to improve game availability. Such activities only had a minor effect on the deciduou…
