Trophic niche features influence microplastic ingestion in Mediterranean fish species
2022
Widespread microplastic (MP) contamination in the marine environment has raised global concern in the last decade. Scientific evidence of the adverse effects of MP on organisms is growing fast and there is urgent need to fulfil the knowledge gaps about the trophic drivers that lead to such contamination processes and resulting impacts. Fish are considered good bioindicators of MP contamination due to their easy availability, high ecological and commercial value, however our understanding of how trophic niche influences MP ingestion is limited. Here, we investigated the occurrence and abundance of MP in the gastrointestinal tract of 8 commercial fish species (Boops boops, Engraulis encrasico…
Estrategias artísticas micropolíticas en el espacio urbano del siglo XXI. Análisis de casos del contexto artístico español y una propuesta expositiva…
2017
Las prácticas artísticas vinculadas a la ciudad y al espacio urbano se han convertido en un proceso artístico de importancia relevante dentro del contexto español sobre todo en estas últimas décadas. Uno de los motivos es el ensalzamiento de la ciudad como el espacio por excelencia de la contemporaneidad, el cual se empezó a definir a partir de la Revolución Industrial y se ha ido redefiniendo con los cambios que han surgido a partir de los nuevos sistemas de producción. La ciudad se ha convertido en el lugar donde artistas y proyectos artísticos crean nuevas relaciones con el espacio urbano conectando con la realidad que conforma un contexto determinado. Esta investigación toma como nexo c…
THE EFFECTS OF GROWTH REGULATORS ON IN VITRO AXILLARY SHOOT PROLIFERATION AND ROOTING OF ERICA MULTIFLORA
2012
Multiple shoots were induced on nodal segments of a mature plant of Erica multiflora L. Axillary shoots produced on uncontaminated explants were excised, segmented, and recultured on the same medium. The effect of Anderson medium, augmented with different concentrations of 2iP either singly or in combination with NAA, as potential medium for shoot multiplication by nodal segments was investigated. In the following experiment equal molar concentrations of four cytokinins (2iP, kinetin, zeatin, and BA) were studied for ability to induce axillary shoot development from single node stem segments. The highest rate of axillary shoot proliferation was induced on Anderson medium supplemented with 1…
Is It Possible to Produce Certified Hazelnut Plant Material in Sicily? Identification and Recovery of Nebrodi Genetic Resources, in vitro Establishme…
2021
Eight Sicilian cultivars of hazelnut (Corylus avellanaL.), namely-Curcia, Nociara Collica, Panottara Collica, Panottara Galati Grande, Parrinara, Panottara Baratta Piccola, Enzo, and Rossa Galvagno, registered into the Italian Cultivar Register of fruit tree species in 2017 were selected from Nebrodi area and establishedin vitro. The aim of the work was to carry out the sanitation of the cultivars and get virus-free plants from the most important viral pathogen threat, theapple mosaic virus. Virus-free plant material is essential for the production of certified plants from Sicilian hazelnut cultivars, complying the CE (cat. CAC) quality and the technical standards established in 2017 for vo…
In Vitro Regeneration of
2019
Three caper (Capparis spinosa L.) biotypes grown on the Sicilian island of Salina (38°33′49″ N) were micropropagated to evaluate two different in vitro culture systems: one using the traditional solid medium, and the other based on liquid culture in a PlantForm bioreactor. PlantForm is a temporary immersion system (TIS), a new propagation method in which the shoots undergo temporary immersion in a liquid medium in order to avoid the accumulation of gas through forced ventilation. This study proposes a protocol to improve the efficiency of in vitro propagation of caper plants, while also reducing production costs, because of the elimination of the gelling agent, and manual labor, requiring l…

Microbial bioresources for rehabilitation of natural and anthropogenic deserts
2012
Arid lands and deserts cover one fifth of the earth’s land surface and they are currently increasing due to the global warming. Besides the natural desert settings, human activities lead to the desertification of certain areas: municipal landfills and caves are the most common examples of such anthropogenic deserts. Massive pollution and lack of natural soil profiles create harsh conditions and hinder the spontaneous rehabilitation of such areas. Phytoremediation is often used for renaturalization of such degraded soils. Two case studies are presented aiming at demonstrating that the plant-microbe interactions are essential for improving the soil quality and allowing the formation of crops.…

INTRODUCCIÓN El embarazo ectópico (EE) es una complicación precoz de la gestación en la cual un óvulo fecundado se implanta en un sitio distinto al endometrio de la cavidad uterina. siendo el lugar más frecuente la trompa de Falopio (95-98%). Su incidencia resulta variable en la literatura médica, oscilando entre el 0,6 y el 2% de los embarazos documentados, presentándose con picos más altos en la adolescencia. Este continúa siendo la principal causa de muerte materna en las primeras etapas de la gestación (4-10% de las muertes relacionadas con el embarazo en países desarrollados) y una de las urgencias quirúrgicas más frecuentes del primer trimestre. El EE no es solo una causa importante d…

Isolation and characterization of nuclear microsatellite loci in the northern shrimp, Pandalus borealis
2012
Published version of an article published in the journal: Conservation Genetics Resources. Also available from the publisher at: http://dx.doi.org/10.1007/s12686-011-9486-4 We developed and characterized 20 microsatellite primer loci for the northern shrimp Pandalus borealis. All 20 loci were polymorphic with number of alleles ranging from 3 to 36 and with observed heterozygosity between 0.04 and 0.93. In addition, we tested the utility of these markers in three related shrimp species, P. montagui, Atlantopandalus propinqvus and Dichelopandalus bonnieri. These new markers will prove useful in the identification of stock structure and hence, assessment of the commercially important species P…
