Full text linkAssessing the bioeconomy’s contribution to evidence-based policy: A comparative analysis of value added measurements
Full text linkThis paper reviews the main approaches found in the literature to measure the size of the European bioeconomy. The various estimations published might be confusing at first sight, reporting a value added of the European bioeconomy within the large range of EUR 881 billion to EUR 2.3 trillion. However, each approach is best suited to measuring a different aspect of the bioeconomy. Using the different approaches, we estimate that markets of bio-based products and energy generate EUR 730-790 billion of value added, the use of biomass within the European economy generates EUR 670 billion of value added, and the sourcing of core bioeconomy industries with goods and services generates EUR 270 billion of value added. There is no evidence of an increased use of biomass inputs in EU industries in substitution of fossil resources, nor of a decreasing dependence of traditional bioeconomy industries towards fossil resources over the period 2005-2015.Bioeconomymethodologiesbio-based industriesvalue addedEuropeinput-output tablesPublishe

Impacto inmediato del laboreo sobre la calidad del suelo en un viñedo en la D.O.P. Somontano (Huesca, Aragón) manejado con cubierta espontánea
Full text linkEn viñedos, el manejo del suelo con cubiertas vegetales puede generar una competencia por agua y nutrientes, lo que podría disminuir el rendimiento. A medio–largo plazo, la implantación de una cubierta vegetal en el viñedo puede mejorar las propiedades del suelo, pero dicho impacto es muy dependiente de las condiciones edafoclimáticas de cada parcela. Por ello, este trabajo tiene como objetivo determinar el efecto de un laboreo superficial sobre diversos indicadores de salud del suelo y el estado hídrico en un viñedo del Somontano (Huesca) gestionado con una cubierta espontánea durante los cinco años previos. Las propiedades físico–químicas del suelo apenas se alteraron con el laboreo, mientras que las biológicas (actividad microbiana y diversidad de artrópodos) se redujeron drásticamente. Además, la cubierta vegetal no tuvo un impacto negativo sobre el estado hídrico de la vid. Esto sugiere que la cubierta vegetal puede ser una alternativa sostenible frente al laboreo en la zona de estudio.Immediate impact of tillage on soil health in a D.O.P. Somontano (Huesca, Aragón) vineyard previously managed with spontaneous vegetation. In vineyards, soil management using plant covers might cause a competition
for water and nutrients, which could lead to reductions in yield. In the medium to long term, establishing a vegetal ground cover in the vineyard may enhance soil properties, but this impact strongly depends on the edaphoclimatic conditions of each plot. Consequently, this work
aims at determining the effect of a surface tillage on several soil health indicators and the water status in a vineyard located in Somontano
(Huesca) that has been managed with spontaneous vegetation during the previous five years. Soil physical and chemical properties were not
altered by tillage; however, biological properties (microbial biomass, diversity of arthropods) were considerably reduced. Moreover, spontaneous vegetation did not affect grapevine water status. This suggests that establishing a
plant cover is a sustainable alternative to tillage under the conditions of this studyEste estudio forma parte del programa AGROALNEXT y ha sido financiado por MCIN con fondos de la Unión Europea NextGenerationEU

The efficiency of in vitro ovine embryo production using an undefined or a defined maturation medium is determined by the source of the oocyte
Full text linkIn vitro oocyte maturation can be influenced by oocyte source and maturation media composition. The aim of the present study was to compare the efficiency of a defined in vitro maturation medium (TCM199 supplemented with cysteamine and epidermal growth factor; Cys + EGF) with an undefined medium (TCM199 supplemented with follicle-stimulating hormone and follicular fluid; FSH + FF) for in vitro production (IVP) of ovine embryos, using oocytes obtained by laparoscopic ovum pick-up from FSH-stimulated [n=11; 158 cumulus-oocyte complexes (COCs)] and non-stimulated (n=16; 120 COCs) live ewes, as well as abattoir-derived oocytes (170 COCs). The produced blastocysts were vitrified and some of them were transferred to synchronized recipients. The best and the worst final yields of embryo IVP observed in this study were obtained using oocytes from FSH-stimulated ewes matured in FSH + FF (41.3%; 33/80) and in Cys + EGF (19.2%; 15/78) medium, respectively (p<0.01). No significant differences between both media were attained in the blastocyst development rate or in the final yield of embryo IVP using oocytes from non-stimulated ewes or abattoir-derived oocytes. The overall in vivo survival rate of the transferred vitrified blastocysts was 13.1% (8/61), without significant differences between oocyte sources or maturation media. In conclusion, under the experimental conditions of the present study, TCM199 supplemented with cysteamine and EGF is a convenient defined maturation medium for IVP of embryos from oocytes of live non-stimulated ewes or from oocytes of abattoir-derived ovaries. However, the best final yield of embryo IVP observed in this study was attained when oocytes came from FSH-stimulated donors and TCM199 was supplemented with FSH and follicular fluid.© 2010 Blackwell Verlag GmbH.This work was supported by M de Educacio´n y Ciencia (Project

Dynamics of Leiodes cinnamomeus (Coleoptera: Leiodidae) Populations in a Black Truffle Orchard From Northeast Spain
No full textBlack truffle, Tuber melanosporum Vittad., production is increasing due to an improvement in cultivation management and to the demand for this highly appreciated fungus. However, this intensification of truffle cultivation has led to the appearance of problems related to pest incidence. Specifically, the truffle beetle, Leiodes cinnamomeus (Panzer, 1793) (Coleoptera: Leiodidae), causes significant losses in black truffle marketability. However, its biology is still poorly known, and no effective agro-ecological methods exist to mitigate its damage to the truffles. This study aimed at assessing the population dynamics of L. cinnamomeus over four seasons (2019–2023) in an orchard located in NE Spain and relating these dynamics to weather variables and damage to truffle fruit bodies. Moreover, we described the diversity of arthropods captured in the traps in search of potential natural enemies of this beetle. The maximum population peak was observed in November, except for a single season in which it occurred in December. Moreover, the sex ratio was balanced (0.54 on average), but it varied over the growing season and among years. Significant and positive relationships of the population density of truffle beetles with air temperature and relative humidity were observed. The number of beetles per trap and day was strongly linked to heat accumulation. Finally, the Carabid Percus (Pseudopercus) patruelis (L. Daufour, 1820) was identified as a natural enemy of L. cinnamomeus. These results could be used in the future for monitoring and predicting truffle beetle populations.BiodiversityEuropean truffle beetlemycophagous insectsnatural enemiesTuber melanosporum Vittadsoil faunaIn pres
