The Emergence of Arboriculture in the 1st Millennium BC along the Mediterranean’s “Far West”
2021
This paper presents the history of the introduction and expansion of arboriculture during the 1st millennium BC from the South of the Iberian Peninsula to the South of France. The earliest evidence of arboriculture at the beginning of the 1st millennium hails from the south of the Iberia from where it spread northward along the peninsula’s eastern edge. The different fruits (grape, olive, fig, almond, pomegranate and apple/pear) arrived together in certain areas in spite of uneven distribution and acceptance by local communities. Grape was the crop with the greatest diffusion. The greater diversity of crops in the southern half of the peninsula is also noteworthy. Their development paved th…
Cordage, basketry and containers at the Pleistocene-Holocene boundary in southwest Europe. Evidence from Coves de Santa Maira (Valencian region, Spai…
2019
In this study we present evidence of braided plant fibres and basketry imprints on clay recovered from Coves de Santa Maira, a Palaeolithic-Mesolithic cave site located in the Mediterranean region of Spain. The anatomical features of these organic fibre remains were identified in the archaeological material and compared with modern Stipa tenacissima (esparto grass). Based on direct dating, the fragments of esparto cord from our site are the oldest worked plant fibres in Europe. Sixty fragments of fired clay are described. The clay impressions have allowed us to discuss the making of baskets and containers. According to their attributes and their functional interpretation, we have grouped th…
Factores predictivos de desarrollo y evolución de infección activa por citomegalovirus en el transplante alogénico de precursores hematopoyéticos
2021
Citomegalovirus (CMV) es una causa elevada de morbimortalidad en el receptor de trasplante alogénico de precursores hematopoyéticos (alo-TPH). Con la introducción de fármacos específicos frente al virus el riesgo de sufrir enfermedad orgánica por CMV de estos pacientes se ha reducido notablemente; siendo el tratamiento anticipado la estrategia terapéutica más extendida en el manejo de la infección por CMV en el alo-TPH. Sin embargo, esta estrategia es mejorable. En este sentido, nos propusimos analizar una serie de factores que influyen en la monitorización virológica, la cual es inherente a la estrategia de tratamiento anticipado. Dada la elevada variación inter-ensayo e intercentro de las…
Local response of bacterial densities and enzyme activities to elevated atmospheric CO2 and different N supply in the rhizosphere of Phaseolus vulgar…

Publication Inra prise en compte dans l'analyse bibliométrique des publications scientifiques mondiales sur les Fruits, les Légumes et la Pomme de terre. Période 2000-2012. http://prodinra.inra.fr/record/256699; Altered flux of labile C from plant roots into soil is thought to influence growth and maintenance of microbial communities under elevated atmospheric CO2 concentrations. We studied the abundance and function of the soil microbial community at two levels of spatial resolution to assess the response of microorganisms in the rhizosphere of the whole root system and of apical root zones of Phaseolus vulgaris L. to elevated CO2 and high or low N supply. At the coarser resolution, microb…
Specific adduction of plant lipid transfer protein by an allene oxide generated by 9-lipoxygenase and allene oxide synthase
2006
International audience; Lipid transfer proteins (LTPs) are ubiquitous plant lipid-binding proteins that have been associated with multiple developmental and stress responses. Although LTPs typically bind fatty acids and fatty acid derivatives in a non-covalent way, studies on the LTPs of barley seeds have identified an abundantly occurring covalently modified form, LTP1b, the lipid ligand of which has resisted clarification. In the present study, this adduct was identified as the {alpha}-ketol 9-hydroxy-10-oxo-12(Z)-octadecenoic acid. Further studies on the formation of LTP1b demonstrated that the ligand was introduced by nucleophilic attack of the free carboxylate group of the Asp-7 residu…
Behavioral and hippocampal evoked responses in an auditory oddball situation when an unconditioned stimulus is paired with deviant tones in the cat: …
1995
Event-related potentials (ERP) in the areas CA1, CA3 and dentate fascia (Df) of the hippocampal formation were recorded during an oddball situation in the cat. A rewarding electrical stimulation of the lateral hypothalamus (US) was paired with deviant tones (2500 Hz) that occurred randomly in a series of the standard tones (2000 Hz) given to the left ear. In addition to developing orienting head movements to the side of the deviant tones, an increase in the amplitude of parallel hippocampal ERPs was observed. Both the behavioral and neural responses appeared not until a 50 ms latency range. Furthermore, time-amplitude characteristics of the ERPs corresponded to time-acceleration characteris…
Plantas del herbario del Hermano Bianor en el Museo La Salle Colegio Paterna (Valencia, España). Plants of the Brother Bianor herbarium in the La Sal…
2018
Resumen. El presente estudio muestra la documentación, digitalización e informatización de la obra completa del Hermano Bianor contenida en el Museo La Salle de Paterna (Valencia, España). Esta colección clásica recoge parte de las recolecciones que el propio Bianor llevó a cabo durante su estancia en las Islas Baleares a principios del siglo XX. La colección consta de 1214 pliegos de herbario recolectados entre los años 1905 y 1916 por diferentes localidades de la isla de Mallorca, especialmente en los municipios de Sóller y Palma de Mallorca. Además de una breve biografía del autor, se incluyen detalles sobre el origen de la colección, datos sobre los municipios donde se recolectaron las …
A method for rapid implantation of multielectrode systems.
1991
The implantation of several chronic electrodes at the same time was needed for the studies in which both evoked slow potential and multiple unit neural activity of different brain sites were recorded during classical conditioning in freely moving cats. The recording electrodes were made of 25-75 microns insulated stainless steel or nichrome wires which were inserted into a thin hypodermic needle of a fixed, calibrated length. The fast implantation system described here is based on the use of a stereotaxic frame as a stand for a drill and as a support for an electrode holder with which the electrodes were implanted through precision holes drilled directly according to the coordinates of the …
Effects of plant density on Rosmarinus officinalis L. and first tests of mechanical transplanting
2004
Tests for evaluating the agronomical response of Rosmarinus to four plant densities were carried out from 1998 to 2001, on a local ecotype of Rosmarinus, in an area having the typical soil and climatic conditions of the Sicilian inland hilly environment. Data about biometric characteristics (plant height, number of stems per plant, fresh and dry yield), the ratio between leaf weight and dry weight and the ratio between stem weight and dry weight, both expressed as percent, were monitored. Moreover, essential oil analyses were carried out for each plant density. The results showed that the plant density positively influenced the fresh and dry yield, while it negatively affects the number of …
Estudio de la actividad biocida de aceites procedentes de plantas aromáticas sobre Tetranychus urticae y Ceratitis capitata
2014
Se ha estudiado la actividad biocida de aceites esenciales extraídos de plantas aromáticas como el romero (Rosmarinus officinalis L.) y la salvia (Salvia officinalis L.) sobre la araña roja (Tetranychus urticae Koch) y la mosca de la fruta (Ceratitis capitata Wiedemann). El aceite esencial de salvia a la concentración del 1% se mostró capaz de atraer adultos de C. capitata. La mayor actividad frente a la araña roja se observó por parte del aceite esencial de salvia, provocando, con gran rapidez, una alta tasa de mortalidad. El aceite de salvia al 0,25% consiguió reducir el nivel de puesta de T. urticae, llegando incluso a tasas de reducción de un 50%.
