Fitting the Stocking Rate with Pastoral Resources to Manage and Preserve Mediterranean Forestlands: A Case Study
2015
Pasture practices have affected Mediterranean forest ecosystems for millennia, and they are still quite widespread in mountainous areas. Nevertheless, in the last decades, the stability of forest ecosystems has been jeopardized due to the abandonment of traditional agro-pastoral practices, so that the gradual reduction of open areas due to progressive succession processes has caused a high increase of grazing pressure by livestock and wild ungulates feeding on forest areas. This paper aims at showing a methodological approach for evaluating the effect of applying measures in order to improve the grazing value of grasslands and ecotonal patches and lower the grazing impact on native woodland…
Past cover modulates the intense and spatially structured natural regeneration of woody vegetation in a pastureland
2020
Made available in DSpace on 2020-12-12T02:34:44Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-03-01 Università degli Studi di Palermo Ministero dell’Istruzione, dell’Università e della Ricerca Vegetation natural regeneration after agricultural abandonment is changing the landscape patterns in many areas worldwide. However, the expansion rate, spatio-temporal dynamics, and the role of past vegetation cover in shaping such patterns are still barely quantified in fine and meso scales. Here, we aim to quantify the expansion rate and assess the spatio-temporal patterns and the effects of past cover on natural woody vegetation cover increase. We sampled woodland and shrubland cover from …
Trophic and spatial complementarity on seed dispersal services by birds, wild mammals, and cattle in a Mediterranean woodland pasture
2021
Made available in DSpace on 2022-05-01T09:47:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-11-01 Università degli Studi di Palermo CYTED Ciencia y Tecnología para el Desarrollo Federación Española de Enfermedades Raras Most earth surfaces have undergone intensive land-use changes, creating habitat mosaics. Seed dispersal by animals is a crucial process in such mosaics, but community-wide studies comparing the functional complementarity and response to man-imposed habitat heterogeneity are rare. Here, we investigate the trophic and spatial seed dispersal networks underpinning a strong, woody vegetation expansion over a pastureland inside the largest forest remnant in western Sici…
Bird abundance and richness in ten Mediterranean agroforestry systems
2019
Since the last century agriculture is strongly promoting the simplification of the landscape. The LIFE Desert Adapt project is been developed across 1000 hectares in Italy, Spain, Portu-gal and has the objective of implementing integrative agroforestry-based land use planning and management, and one of the indicators to evaluate the project effectiveness is birds richness and abundance. Here we present the results of the first assessment and explore the relationships with the main vegetation cover types. We established 68 sampling points where we recorded bird abundance and richness. In total we registered 57 bird species, sampling points surrounded by woodlands presented 50 species, while …
Effect of Vibration on the Quality of Strawberry Fruits Caused by Simulated Transport
2016
Mechanical damage of agricultural products is one of the main problems in the harvest and postharvest chain due to the large economic loss that the shelf life reduction could generate. Measurements of change in the chemical components of highly perishable products and microbial growth under different static and dynamic loads is the first step in the development of intelligent logistic units that could help in predicting the residual shelf life in order to minimize losses along the supply chain. In our research, the effects of vibration along the supply chain of a case study were analyzed on strawberry (Fragaria x ananassa) and woodland strawberry (Fragaria vesca) in terms of microbiological…
«Il sunt si biaus que c'en est une mervoie a voir». Zoologie e teratologie nel Devisement dou monde
2016
L’articolo ha come oggetto le descrizioni animali e teratologiche del Devisement dou monde. In particolare, la fauna poliana con le sue estremizzazioni mostruose e meravigliose viene indagata sul doppio filo del testo franco-italiano del Devisement (accompagnato, laddove necessario, dall’ausilio delle redazioni toscana e latina) e dell’iconografia rappresentata dalle miniature contenute in quattro codici del Devisement/Milione (mss. Royal 19 D I, Bodley 264, BNF fr. 2810, Arsenal 5219). The present article investigates animal and teratological descriptions of theDevisement dou monde. Particularly, Marco Polo’s fauna and its monstrous and marvelous extremes are explored both in the Franco-It…
Kulebele, śląski dog i gumiklejzy w pudełku, czyli o kuchni śląskiej w nowych odsłonach
2021
The article is devoted to Silesian cuisine which has recently become the subject of various activities focused on new ways of presenting it and reflecting directly the current global trends in gastronomy. Using two characteristic phenomena of street food and fusion cuisine, the author shows that specific dishes of Silesian cuisine have been reinvented thanks to the individual chefs’ visions. The transformation processes that have been taking place recently in the field of regional cuisines are most clearly visible in gastronomic establishments, where you can taste “old” dishes with new flavours and in new arrangements, often very surprising, such as hajer (rye flour tortilla with beef roula…
Effect of soil and canopy factors on vegetation of Quercus robur woodland in the boreo-nemoral zone: A plant-trait based approach
2013
Abstract The aim of the study was to determine the effect of soil and canopy on the understory vegetation of Quercus robur stands in Latvia, located in the boreo-nemoral zone. To determine the main processes regulating formation of the plant communities, the understory vegetation of Q. robur stands was described using plant traits. Vegetation and soils were described in 24 plots representing contrasting soil types and tree species composition. Redundancy analysis was used to determine the relation between vegetation, described using plant traits (proportion of species with each trait), and soil and canopy factors. About 50% of the variation in vegetation described by plant traits was explai…
Convergencia digital y software libre en el EEES. Algunas experiencias con Gretl
2012
Resumen La utilizacion de software libre y abierto (Free Open Source Software: FOSS) aporta numerosas ventajas en el ambito universitario, que resultan au n mas patentes en el marco del Espacio Europeo de Educacion Superior (EEES). Las principales caracteristicas del FOSS (libertad de uso de programas, acceso al codigo fuente, estudio y adaptacion, distribucion de copias e implementacion de mejoras que beneficien a toda la comunidad) aparecen relacionadas con competencias como creatividad, trabajo en equipo o adap tacion a nuevas situaciones. Este trabajo examina el papel del software libre en el ambito universitario y su potencial para reducir la brecha digital, presentando tambien algunas…
Controversies in the transition from paper and electronic textbooks to digital content
2018
Cabe pensar, dada la magnitud económica y cultural que representa el libro en nuestra sociedad, ya sea en soporte papel como electrónico, que los dos van a convivir largo tiempo. Los libros de texto, en consecuencia, correrán una suerte muy semejante. El cambio actual lo focalizamos en la transformación de los libros de texto en contenidos digitales con distintos formatos y vías de acceso. De este proceso estudiamos las controversias que suscitan estos cambios, en tanto que son reflejo del grado de asimilación por parte de la ciudadanía de las referidas innovaciones tecnológicas. Mediante estrategias etnográficas, nos acercamos a distintos agentes escolares para tratar de comprender inducti…
